Uma umthengi wephrojekthi engithumelela ibhili lamanani anemigodi yomhlaba engu-200 kuyo, into ayiqhathanisayo cishe njalo intengo yeyunithi. Ngiyaqonda ukuthi kungani - yinombolo kuphela ekhasini. Kodwa ngemva kweminyaka engu-12 yokuhlola imigodi yokuthumela kumaphrojekthi okufaka umhlabathi emazwenikazi amane, ngingakutshela ukuthi intengo yeyunithi iyinombolo encane kakhulu ethembekile kulokhu kuqhathanisa. Izindleko ezifakiwe zemigodi yomhlaba ziyinqwaba yabashayeli abahlanu - umkhiqizo, imithwalo, umsebenzi wokufaka, ukulingana komthwalo, kanye nempilo yesevisi - futhi ukhonkolo uwina eyodwa yazo kuhlelo lokusebenza olujwayelekile lokufaka umhlabathi. Ngizobeka izinombolo zangempela zesigaba somthwalo etafuleni (kusukela emithonjeni ye-EN 124 kanye ne-AASHTO), ngigcine uhlangothi lwemali luthembekile ngaphandle kokusungula uhlu lwamanani, futhi ngikunike ithuluzi lesinqumo engilisebenzisa ekucaphuneni kwami.
TL;DR — Abashayeli Bezindleko Abahlanu, Ababekwe Ezingeni Lokuthi Abathengi Babaphuthelwa Kangaki
- Impahla iyindlela engabizi kakhulu yokukhokha.Ngibuka igebe lokuthutha impahla lisusa inzuzo yentengo yekhonkrithi cishe kuwo wonke ama-oda okuthumela ngaphandle: umgodi wekhonkrithi owenziwe kusengaphambili unesisindo esiphindwe kaningi kune-polymer, ngakho-ke ekuthunyelweni kwe-oda lemigodi engu-200 ukuthunyelwa nokuphathwa kwayo kuvame ukwedlula igebe lentengo yeyunithi.
- Umsebenzi wokufaka uthanda i-polymer ngokuklama.Ngifaka umgodi we-polymer onomuntu oyedwa, akukho crane, futhi akukho ukupholisa; umgodi wekhonkrithi udinga imishini yokuphakamisa, izingubo zokulala, futhi ngokuvamile isikhathi sokusebenza endaweni.
- Ukushaya kwe-Load class fit, ukuqhosha kwe-Load class.Ngiphawula ukuthi i-EN 124 class A15 (15 kN test load) ihlanganisa izindawo zabahamba ngezinyawo kanti i-B125 (125 kN) ihlanganisa izindlela zabahamba ngezinyawo kanye nezindawo zokupaka izimoto — yilapho kuhlala khona imigodi yokuhlola umhlaba; Ngibiza ikhono le-D400 endaweni yokuhlola ngokuthi imali echithiwe.
- Impilo yenkonzo iyincazelo, hhayi ithemba.I-EN 124-6:2015 idinga ukuthi izembozo ze-PP/PE/PVC-U ziqiniswe nge-UV, futhi imigodi yethu ye-polymer iphila iminyaka engaphezu kwengu-50 - imifantu yekhonkrithi, ama-spall, futhi igqwala ukuqina kwayo enhlabathini enolaka.
- Ukhonkolo usanqoba ndawana thize.Ngishiya ithrafikhi yezimoto ezisindayo ngamabomu (i-AASHTO H-20: umthwalo wamasondo angu-16,000 lb, ubufakazi obungu-40,000 lb) kukhonkrithi elungisiwe kusengaphambili — futhi ngiyakufakazela lokhu ngemininingwane engezansi.
Lokho Okwenziwa Yi-Earth Pit Empeleni (Futhi Kungani Lokho Kunquma Izibalo Zezindleko)
Umgodi womhlaba — obizwa nangokuthi umgodi wokuhlola noma igumbi lokumba umhlaba — yindawo yokufinyelela phezu kwenduku yomhlaba noma uxhumano lwegridi: ivikela ijoyinti, igcina indawo yokuhlola yomile ngokwanele ukuthi ivuleke, futhi ivumela ithimba lakho lokulungisa ukuthi libambe umhloli ku-electrode minyaka yonke. Imigodi yethu ihlinzeka ngokufakwa komhlaba, ukuvikelwa kombani, ukuvimbela ukuphazamiseka, kanye nokufakwa komhlaba okuphikisana nokuqina ezindaweni zamandla, ujantshi, ukwakhiwa, izimayini, amakhemikhali, kanye nezimboni — noma kuphi lapho uxhumano lomhlaba ludinga ukuqashwa ngesikhathi sangempela. Ngigcizelela umsebenzi ngoba ulungisa isidingo somthwalo: indawo yokuhlola umhlabathi isendaweni eseduze, endleleni yabahamba ngezinyawo, ekhoneni legceke, noma endaweni ehlotshiswe kahle — indawo yabahamba ngezinyawo. Angikaze ngibone muntu ehleli emzileni weloli.Ngenxa yokuthi umsebenzi womgodi ukufinyelela nokuvikela kunokuthwala umthwalo wesakhiwo, isigaba somthwalo osidingayo ngempela ngokuvamile yi-A15 noma i-B125 — futhi lelo qiniso elilodwa libumba kabusha lonke ukuqhathaniswa kwezindleko ze-polymer-versus-concrete.
Izinombolo zomthwalo, kusukela ezindinganisweni ngokwazo
Ngicaphuna amakilasi omthwalo emithonjeni eyinhloko ngoba “umthwalo osindayo” awusho lutho ngaphandle kwenombolo. Ngithatha la makilasi ngqo kusuka kuhlaka lwaseYurophu, i-EN 124-1:2015, oluwachaza ngomthwalo wokuhlola: A15 ku-15 kN ezindaweni ezisetshenziswa kuphela ngabahamba ngezinyawo nabahamba ngamabhayisikili, i-B125 ku-125 kN yezindlela zokuhamba ngezinyawo kanye nezindawo zokupaka izimoto, i-C250 ku-250 kN yeziteshi eziseceleni komgwaqo, kanye ne-D400 ku-400 kN yezindlela zokuhamba. Ingxenye eqondene nezinto ze-thermoplastics,I-EN 124-6:2015 yezimbozo ze-PP, PE, kanye ne-PVC-U, isebenza ekufakweni kwekilasi A15 kanye ne-B125 futhi idinga ukuthi yonke ingxenye yenziwe ngento eyodwa, eqiniswe yi-UV. Ngishintsha amagama eNyakatho Melika: ngayinyeumhlahlandlela wokulinganisa umthwalo womkhiqizi we-EJ, ama-castings angewona awethrafikhi aphatha kufika ku-2,500 lb, umthwalo olula umboza i-2,500–16,000 lb, kanti isilinganiso se-AASHTO H-20 esaziwayo sisho umthwalo wesondo ongu-16,000 lb onesilingo esingavinjelwa i-40,000 lb ku-pad engu-9×9 intshi. Ngihlela umkhuba wokukhetha nenhlangano yezohwebo yase-UK.Umhlahlandlela we-BPF Pipes Group wamakamelo okuhlola epulasitikiIzindawo zabahamba ngezinyawo zeqembu 1 zidinga i-A15 (ukuhlolwa kwe-15 kN), izindlela zabahamba ngezinyawo zeqembu 2 kanye nezindawo zokupaka izimoto zidinga i-B125 (ukuhlolwa kwe-125 kN), kanye neklasi yokungena ngemoto ye-A35 phakathi kwezindlela zokungena zangasese.
Lapho ukhonkolo udingeka khona ngempela
Ngingumphathi wokuthengisa womkhiqizi wemigodi ye-polymer okutshela ukuthi kufanele uthenge nini ukhonkolo, ngakho funda lokhu ngokweqiniso. Imininingwane yebhidi likamasipala ka-2024 ephethwe yi-Ukwakhiwa kwe-LCS kwephrojekthi yaseBerkeleyikhombisa ukuthi onjiniyela babela kanjani izinto zokwakha: imigodi yama-handhole namabhokisi emigwaqweni kanye nezindlela zomgwaqo ezihlosiwe kumele zibe ukhonkolo oqoshiwe kusengaphambili ku-AASHTO H-20; izindawo zokungena kanye nezindawo zokupaka ezinezimoto ezisindayo ezingahlosiwe ngezikhathi ezithile zingaba ukhonkolo oqoshiwe kusengaphambili ku-SCTE 77 Tier 15; izindawo zabahamba ngezinyawo zithatha iTier 8; kanti izindawo zabahamba ngezinyawo kuphela zingasebenzisa amayunithi e-fiberglass ahlolwe ku-3,000 lbf (13,345 N). Ngifuna uqaphele iphethini: izinto zilandela ikesi lomthwalo, kanti ikesi lomthwalo lilandela ithrafikhi. Uma umgodi wakho womhlaba uhleli lapho amaloli ashayela khona ngamabomu, ngizokutshela ukuthi uthenge ukhonkolo oqoshiwe oqoshiwe kusengaphambili - owethu awuwona umkhiqizo ofanele futhi neyunithi ye-polymer yomunye umuntu ayifanele.
Umshayeli 1 — Intengo Yeyunithi: Inombolo Eyodwa Eqhathaniswa Yiwo Wonke Umuntu
Nansi ingxenye lapho ngigcina khona isithembiso sami sokungaqambi uhlu lwamanani: amanani emigodi ahamba ngezimakethe ze-resin, izimakethe zesimende, ivolumu yama-oda, kanye nendawo okuya kuyo, ngakho-ke noma yiliphi inani ledola engiliphrintile lizophelelwa yisikhathi phakathi nekota. Ngitshela abathengi ukuthi yini engahambi: isakhiwo. Ngibona i-polymer ebunjiwe kanye nemigodi emincane yekhonkrithi ebekwe kusengaphambili isendaweni efanayo ebanzi yentengo yefektri - i-concrete ngezinye izikhathi iphansi ngevolumu yezimpahla, i-polymer ngezinye izikhathi iphansi nge-molded consistency. Ngicaphune kokubili embonini efanayo (umugqa wethu we-AF-N0658 usebenzisa izinhlobo ze-PVC kanye nekhonkrithi), futhi ngitshela abathengi into efanayo njalo: intengo yefektri yesango ingumzuliswano wokuqala kwezinhlanu, futhi umzuliswano obaluleke kakhulu kuma-oda okuthumela ngaphandle.
Umshayeli 2 — Impahla: Lapho Ikhonkrithi Ilahlekelwa Yi-oda Lokuthumela Ngaphandle
Ngiphatha isisindo njengesiphetho kwezokuthutha. Umgodi wekhonkrithi owenziwe kusengaphambili onamandla afanayo unesisindo esiphindwe kaningana kunesisindo somgodi we-polymer obunjiwe - okungukuthi i-physics, hhayi ukumaketha, futhi udlula kuzo zonke izinyathelo zokuthutha: amayunithi ambalwa ngephalethi ngayinye, amaphalethi ambalwa ngesitsha ngasinye, umthwalo ophezulu wolwandle ngeyunithi ngayinye, amaloli anzima angaphakathi ezweni, kanye nemikhawulo yokuphatha ngesandla kuzo zombili izinhlangothi. Imikhumbi yethu ye-polymer ifakwa epaketheni langaphakathi, amabhokisi, kanye namaphalethi avela echwebeni laseNingbo noma eShanghai - uhlelo lokupakisha oluklanyelwe isisindo esincane - futhi ku-oda lephrojekthi evamile ye-200-kuya-500-pit, ukonga imithwalo kuphela kuvame ukwedlula noma yimuphi umehluko wentengo yefektri nesango.Ngenxa yokuthi imithwalo yolwandle ikhokhiswa ngobuningi kanye nama-bracket esisindo kunokuba ikhokhiswe ngenani lomkhiqizo, ukuthumela umkhiqizo wempahla esindayo emhlabeni wonke kuyindlela esheshayo yokubhubhisa inzuzo yawo yentengo.Ngisebenzisa lezi zibalo njalo ngezingcaphuno zangempela, yingakho umbuzo wami wokuqala kumthengi oqhathanisa izindleko ungabi “yinani abalicaphunisile” kodwa “yinani elilinganisiwe.”
Umshayeli 3 — Ukufakwa: Umuntu Oyedwa Uma kuqhathaniswa Neqembu
Ngiyayeka ukuba mnene endaweni: ukuqhathanisa akusondele. Ngichaza ukufakwa kwe-polymer njengokuthi: mba iphakethe, beka umgodi phezu kwe-electrode, yenza uxhumano, gcwalisa emuva, qedile — isisebenzi esisodwa, amathuluzi esandla, akukho ukulinda. Ngibuka ukufakwa kwekhonkrithi kwengeza ukuphakamisa (izandla ezimbili okungenani, usizo lomshini okubi kakhulu), ungqimba lwemibhede olulungisiwe, izihlalo eziqaphile ukuze kugwenywe imithwalo ekhombayo ephula umngcele, kanye nokungaxoleli uma umgodi uwela ugobile. Ngiphinda umehluko wabasebenzi ekusakazweni kwemigodi engu-200 futhi ukufakwa kuba yindleko enkulu kakhulu engalawuleka kuphrojekthi.Ngenxa yokuthi umsebenzi wokufaka ulinganiswa ngokuhambisana nenani lemigodi kuyilapho izindleko zobunjiniyela zingalingani, inzuzo yokufaka i-polymer ngeyunithi ngayinye ikhula kakhulu njengoba iphrojekthi ikhula.Isisho sethu sedatha salokhu silula ngamabomu — “ukufakwa okulula, kushibhile” — futhi siyasinda ekuxhumekeni nezindawo zomsebenzi zangempela.
Umshayeli 4 — Ukulingana Kwesilinganiso Somthwalo: Yeka Ukukhokhela Amandla Ongakwazi Ukuwasebenzisa
Ngibona lo mshayeli ekhetha i-polymer ngendlela abathengi abangayinaki kakhulu. Uma indawo yakho yokuhlola isendaweni yabahamba ngezinyawo, incazelo efanele yi-A15; indawo yokupaka izimoto, i-B125. I-EN 124-6 ikhona ngqo ukuqinisekisa izembozo ze-thermoplastic zalezo zigaba ezimbili, kanye nokuqiniswa kwe-UV okuphoqelekile. Ngibiza inzuzo yekhonkrithi — amandla e-D400 carriage uma iqiniswa ngensimbi — amandla ongeke uwasebenzise endaweni yokuhlola umhlabathi, futhi ngiyenqaba ukuvumela abathengi ukuthi bakhokhele. Isiyalo sisebenza ngazo zombili izindlela: uma umgodi owodwa endaweni yakho uhlala emzileni wokulethwa, lowo mgodi — futhi lowo mgodi kuphela — uthola isembozo esilinganiselwe. Ngisindise abathengi imali yangempela ngokuhlukanisa i-oda lemigodi engu-200 libe amayunithi e-polymer angu-195 kanye namayunithi alinganiselwe angu-5 ngemva kokubuka uhlelo lwabo lomgwaqo kanye.
Umshayeli 5 — Impilo Yesevisi: Izindleko Ezifika Kunyaka We-12
Ngifunde ukuthi ingqalasizinda egqitshwe phansi iyahluleka buthule. Ngibona imigodi yekhonkrithi iqhekeka ngaphansi kwemijikelezo yokuncibilika kweqhwa, i-spall lapho ama-chloride efika khona ekuqiniseni, futhi alahlekelwe yizivalo zawo zensimbi noma zensimbi ukuze zigqwale enhlabathini emanzi, enolaka lwamakhemikhali lapho izinhlelo zokufaka umhlabathi zigxila khona. Umgodi we-PP, PE, noma we-PVC-U oqiniswe yi-UV awunawo amandla okugqwala, awunawo ungqimba lwekhonkrithi lokugqwala, futhi - ngokwemithetho yezinto ze-EN 124-6 - iphakheji ye-UV egunyaziwe yengxenye eveziwe. Silinganisa umugqa wethu womgodi womhlaba we-polymer eminyakeni engaphezu kwengu-50 yokuphila kwenkonzo, futhi ngibona lokho njengokugcina indawo efanele yeyunithi.Ngenxa yokuthi umgodi womhlaba uvikela ingxenye eyodwa kumele uyifinyelele impilo yonke yesistimu - uxhumano lwe-electrode - umgodi ohluleka intela yonyaka we-12 njalo ngonyaka osele wesistimu yokumisa ngomshini onomsebenzi wokuwushintsha.
Ngibheka ukufakelwa esikhundleni njengokwemba, umgodi omusha, ukuhlolwa kokuxhuma kabusha, kanye nokuvakashela abasebenzi; ukugwema umjikelezo owodwa wokufakelwa esikhundleni kubaluleke kakhulu kunanoma iyiphi impikiswano mayelana namanani esango lefektri.

Ithuluzi Lokwenza Isinqumo Engilisebenzisa Ekucaphuneni Kwami
Phendula imibuzo emine mayelana nephrojekthi yakho bese i-logic iziqhuba ngokwayo. Ngikwakhile lokhu kwaba yi-interactive checker ngezansi — ukulandelana okufanayo engidlula kukho ezingcingweni zekhotheshini.
Isikhethi Sezinto Zomgodi Womhlaba (I-Cost-Driver Logic)
Lokho Esikwakhayo Nendlela Esikuthumela Ngayo
Okwethuumgodi wokuhlola izinto zepulasitikiumugqa (imodeli ye-AF-N0658) ubunjwe ngezinhlobo ze-PVC noma zekhonkrithi — ngizigcina zombili ngoba ukunikezwa okuthembekile kusho ukunikeza izinto ezifanele ngendawo ngayinye — okulinganiselwe iminyaka engaphezu kwengu-50 ngaphansi komhlaba, ngensizakalo ye-OEM ne-ODM yobukhulu obuthile bephrojekthi kanye nophawu. Kubathengi abakha izinhlelo zokufinyelela okugcwele, ukufanisaizembozo zomhlaba zegumbi lepulasitiki eliningisithwale umklamo wegridi olinganiselwe umthwalo, kanye neyethuIsembozo somgodi oyisikwele we-PVCivala izikhala ezinkulu zokuhlola; umndeni ophelele uhlala ngaphansi kwethuisigaba somgodi womhlaba. Sikhiqiza izingcezu ezingu-50,000 ngenyanga ngaphansi kwe-ISO 9001 ngohlelo lwethu lwe-QC olunesango eliyisithupha — i-IQC, i-IPQC, ukuhlolwa kwengxenye yokuqala, ukukhiqiza ngobuningi, i-OQC, kanye ne-FQC — futhi yonke iyunithi ishiya ukupakisha kwangaphakathi kanye namabhokisi kanye nama-pallet, alayishwe esitsheni eShanghai noma eNingbo. Sibamba isikhathi sokuhola esijwayelekile ezinsukwini eziyi-10 zezingcezu zokuqala eziyi-100, futhi ngixoxisana ngama-oda evolumu ngokumelene nohlelo lwephrojekthi.
Amanothi Ensimu: Amaphutha Okuthenga Engiwabuka Abathengi Bewaphinda
Ngivula amaphethini amathathu ngemuva kwezinqumo ezibiza kakhulu zemigodi yomhlaba. Iphethini yami yokuqala iwukucacisa ngokweqile: lonke inani libhalwa endaweni embi kakhulu yethrafikhi, ngakho-ke ama-pits angu-200 anesilinganiso somthwalo esidingwa yisihlanu sawo. Iphethini yami yesibili ubumpumputhe bokuthutha: ispredishithi yokuqhathanisa ima esangweni lefektri, futhi ibhili yesitsha ifika njengesimanga. Iphethini yami yesithathu i-lifetime amnesia: inketho eshibhile ukuyithenga ithola udumo ngokuqina okungenakho enhlabathini enolaka, futhi umjikelezo wokufaka esikhundleni ufika emgqeni wesabelomali somunye umuntu eminyakeni eyishumi kamuva.Ngenxa yokuthi imigodi yomhlaba iyinto encane yomugqa ene-multiplier enkulu — ukuhlolwa ngakunye komhlaba kuncike kuyo amashumi eminyaka — imizuzu emihlanu echithwayo ukuklanywa kohlelo lwendawo iyisinyathelo esibaluleke kakhulu kukho konke ukuthengwa.
Imibuzo Evame Ukubuzwa: Imibuzo Yokuthengwa Kwe-Earth Pit Evela Kubathengi Bephrojekthi
Iyini imbobo yomhlaba esetshenziswa ohlelweni lokumisa umhlabathi?
Ngikuchaza njengesici sokusebenza kwesistimu yakho yokumba umhlaba: umgodi uhlala phezu kwenduku yomhlaba noma uxhumano lwegridi, uvikela ilunga enhlabathini, ekugcwaleni kwamanzi, kanye nomonakalo ongengozi, futhi unikeza abasebenzi bakho indawo yokufinyelela ehlanzekile yokuhlola ukumelana ngezikhathi ezithile kanye nomsebenzi wokuxhuma kabusha. Ngaphandle kwakho, ukuhlolwa kwaminyaka yonke kuqala ngefosholo. Imigodi yethu ihlinzeka ngokufakwa komhlaba, ukuvikelwa kombani, ukuvimbela ukuphazamiseka, kanye nokufakwa okulwa nokungaguquki kuzo zonke izindawo zikagesi, zesitimela, zokwakha, zezimayini, kanye nezezimboni.
Ingabe umgodi womhlaba we-polymer uqine ngokwanele ukuze kube nesango lokungena?
Kwezimoto, yebo — amazinga ohlaka lwe-EN 124 i-B125 amboza umthwalo wokuhlolwa ongu-125 kN wezindlela zabahamba ngezinyawo kanye nezindawo zokupaka izimoto, kanti i-BS ISO 15398 ingeza ikilasi le-A35 lezindlela zokungena zangasese. Kwethrafikhi yamaloli ehlosiwe, ephindaphindwayo, cha — lowo msebenzi ungowekhonkrithi elungisiwe kusengaphambili ku-AASHTO H-20 (umthwalo wesondo ongu-16,000 lb kanye nokuhlolwa kobufakazi obungu-40,000 lb). Ngiqala ngihlole icala lomgwaqo, bese ezindaweni ezixubile ngihlukanisa i-oda ukuze umgodi ngamunye uthwale isilinganiso esidingwa yindawo yawo.
Yikuphi okushibhile kakhulu - imigodi yomhlaba eyenziwe nge-polymer noma nge-concrete?
Uma kukhulunywa ngezindleko ezifakiwe, i-polymer iwina uhlelo lokusebenza olujwayelekile lokumba umhlaba, futhi ngeke ngiqambe ngokunemba ngamanani eyunithi asunguliwe. Isakhiwo esithembekile: amanani esango lasefektri ahlala endaweni efanayo; i-polymer iwina imithwalo (ingxenye encane yesisindo), ukufakwa (umfakisi oyedwa esikhundleni seqembu), kanye nokuphila kwesevisi (iminyaka engaphezu kwengu-50, akukho ukugqwala noma ukuchithwa). Ikhonkrithi iwina kuphela lapho amandla ayo okulayisha edingeka ngempela - imizila yethrafikhi ehlosiwe - noma lapho umhlinzeki wendawo olungiselelwe kusengaphambili esusa khona imithwalo ngokuphelele kulesi sibalo.
Umgodi womhlaba we-polymer uhlala isikhathi esingakanani ngaphansi komhlaba?
Silinganisa umugqa wethu ngeminyaka engaphezu kwengu-50 yempilo yenkonzo. I-logic yezinto ezibonakalayo iyakusekela: Imigodi ye-PP, PE, kanye ne-PVC-U ayinazo iziqiniseko zensimbi zokugqwala futhi ayinayo i-matrix yesimende yokuqhekeka noma yokuqhekeka, kanti i-EN 124-6 iyalela izinto eziqiniswe yi-UV ezingxenyeni eziveziwe. Enhlabathini emanzi, enosawoti, noma eqandisayo - izindawo eziqondile ezigugisa ukhonkolo ngokushesha - iyunithi ye-polymer yileyo ehlala idina, futhi okudingayo yikudina yilokho okufunayo engqalasizinda egqitshiwe.
Yisiphi isilinganiso somthwalo okufanele ngisichaze emgodini wokuhlola umhlaba?
Ngiyidweba kusukela ku-traffic case: I-A15 (ukuhlolwa kwe-15 kN) kwezindawo zabahamba ngezinyawo kuphela, i-B125 (125 kN) yezindlela zabahamba ngezinyawo kanye nezindawo zokupaka izimoto, i-A35 yezindlela zokungena ezizimele, kanye nokhonkolo olulinganiswe kusengaphambili ku-H-20 kuphela lapho amaloli edlula khona ngamabomu. Umhlahlandlela wokukhetha we-BPF Pipes Group usebenzisa ukuqoqa okufanayo. Izindawo eziningi zokuhlola phansi zise-A15 noma endaweni ye-B125 - hlola uhlelo lwakho lwendawo ngaphambi kokuvumela noma ubani ukuthi akuthengisele amandla endlela endaweni yokuhlolwa.
Ingabe imigodi yomhlaba ye-polymer ingasetshenziswa enhlabathini yasogwini noma enhlabathini enamandla amakhemikhali?
Yebo — ngizincoma ngenkuthalo lapho. Umoya wasogwini kanye nenhlabathi enosawoti noma ene-acidic kuhlasela imigodi yekhonkrithi kabili: ama-matrix spalls kanye nensimbi ehlanganisiwe iyabola. Umgodi we-polymer ozinzile we-UV awunabo ubuthakathaka, yingakho ubudlelwano bethu bokuthumela ngaphandle obusebenza isikhathi eside bungamaphrojekthi asogwini kanye nezimayini lapho imigodi yekhonkrithi yayihluleka khona kusenesikhathi. Qondanisa isilinganiso sekhava necala lomgwaqo futhi umgodi uzohlala isikhathi eside kunesheduli yokulungisa ebhalwe kuwo.
Imigodi yomhlaba ipakishwa futhi ithunyelwa kanjani ukuze ithunyelwe kwamanye amazwe?
Ukupakisha kwethu okuvamile kokuthumela ngaphandle ukupakisha kwangaphakathi kanye namabhokisi kanye nama-pallet, alayishwe esitsheni eShanghai noma echwebeni laseNingbo — isisindo esincane seyunithi yomugqa we-polymer yisona esenza uhlelo lokupakisha lusebenze kahle, futhi luyintambo yezindleko zangempela ohlangothini lwakho lolwandle. Isikhathi sokuhola sithatha izinsuku eziyi-10 ngobuningi obufika ezingcezu eziyi-100, kanye nomthamo omkhulu wephrojekthi ohleliwe ngokumelene nohlelo lwakho lokufaka.
