Ikota edlule umthengi ungithumelele umncintiswanoukuhlolwa kwesifutho sikasawoti wenduku yomhlabathiumbiko futhi wabuza umbuzo owodwa: “Ingabe amahora angu-96 alungile?” Impendulo yami yammangaza: inombolo yayiyiyona ebaluleke kakhulu ekhasini. I-ASTM B117 iyindlela yokusebenza kwegumbi - itshela ilabhorethri ukuthi iqhutshwa kanjani inkungu, futhi yenqaba ngokusobala ukukutshela ukuthi umphumela usho ukuthini empilweni yesevisi. Okunquma ngempela ukuthi lowo mbiko uvikela iphrojekthi yakho yikho konke okuphathelene nokubalwa kwamahora: amapharamitha amahlanu egumbi, ukulungiswa kwesampula, indlela yokuhlola, inani eliphindaphindwayo, kanye nokugunyazwa kwelabhorethri. Ngiyamukela noma ngiyawenqaba ubufakazi bokugqwala kwabaphakeli njalo ngenyanga, futhi lo mhlahlandlela uwuhlelo lokufunda oluqondile engilusebenzisayo - ngezinombolo okufanele zivele embikweni othembekile, ubufakazi obubhalwe phansi bokuthi amahora okufafaza usawoti awahambelani neminyaka, kanye nokuhlola okubomvu okusebenzisanayo ongakusebenzisa kunoma iyiphi i-PDF umhlinzeki akuthumelela yona.
TL;DR — Funda Umbiko Kulolu Hlobo
- I-ASTM B117 ichaza kuphela indawo yokuhlola, hhayi ukudlula/ukwehluleka: indinganiso ngokwayo ithi “ayichazi uhlobo lwesampula yokuhlola noma izikhathi zokudalulwa… noma incazelo okufanele inikezwe emiphumeleni” — ngakho-ke noma yimuphi umbiko ongenazo izindlela zokwamukelwa ezivunyelwene nomthengi awuphelele ngomklamo.
- Umbiko othembekile usho amapharamitha amahlanu egumbi: isixazululo se-NaCl esingu-5%, 35°C ± 2°C, i-pH 6.5–7.2, izinga lokuhlala kwenkungu elingu-1.0–2.0 mL/h ngamasentimitha angu-80², kanye namasampula angu-15–30° ukusuka phezulu; ipharamitha engekho isho ukuthi ukugijima akukwazi ukukhiqizwa kabusha.
- Amahora okufafaza usawoti awaguquki abe iminyaka yesevisi: isethi yedatha yasensimini eyodwa ebhaliwe ikhombisa isampula yamahora angu-200 ehlala iminyaka engu-20 eMumbai kanti isampula yamahora angu-144 yehluleka eminyakeni emibili eNew Delhi - ukuhlangana kwePearson okungu-+0.66 kuphela ngisho naphakathi kwezingxenye zensimbi ezifanayo.
- Endukwini yomhlaba eboshwe ngethusi, ukugqwala okubomvu kungavela kuphela ensimbini eveziwe, ngakho-ke lapho kuvela khona ukugqwala — iziphetho ezisikiwe, imicu, imigqa yokubhala — kukutshela ngqo ukuthi ungqimba lwethusi luhlulekile kuphi, yingakho amanothi okulungiselela isampula ebaluleke kakhulu kunezinhloko zamahora.
- Isihloli sethu samaphuzu angu-8 ngezansi sithola amaphuzu kunoma yimuphi umbiko womhlinzeki ngemizuzu emibili; noma yini engekho emapharamitha egumbi, indlela yokuhlola, noma ukugunyazwa kwelebhu kubuyela emuva nemibuzo ngaphambi kokuvunyelwa.
Lokho I-ASTM B117 Eyikho Ngempela — Umkhuba Wegumbi, Hhayi Isinqumo
Into yokuqala engiyihlolayo kunoma iyiphiInduku yomhlaba ye-ASTM B117Umbiko uwukuthi ngabe umhlinzeki uyaqonda yini ukuthi baphethe ini. Isihloko esigcwele se-B117 yi-Standard Practice for Operating Salt Spray (Fog) Apparatus, kanti igama elisebenzayo lithi “operating.”Isifinyezo se-ASTM International sika-B117-19KuSigaba 1.2 sithi lo mkhuba “awuchazi uhlobo lwesampula yokuhlola noma izikhathi zokuchayeka okufanele zisetshenziswe kumkhiqizo othize, noma incazelo okufanele inikezwe emiphumeleni.” Isigaba 3.2 siyaqhubeka: “Ukubikezela ukusebenza ezindaweni zemvelo akuvamile ukuhlotshaniswa nemiphumela yokufuthwa ngosawoti lapho kusetshenziswa njengedatha yodwa.”Ngenxa yokuthi indinganiso ichaza inkungu kuphela futhi yenqaba ukuchaza umugqa wokugcina, umbiko okhombisa amahora angenazo izindlela zokwamukelwa ezivunyelwene ngazo nomthengi awuwona umphumela wokuhlolwa - umbiko wesimo sezulu ovela ngaphakathi ebhokisini.
Lokhu akusikho ukufunda okufushane, futhi angisiye mina ngedwa engikushoyo.Iphephandaba lobuchwepheshe likaSherwin-Williams mayelana nemikhawulo ye-B117icaphuna iphepha le-SSPC lika-1995 eliphetha ngokuthi le ndlela inikeza "indlela esheshayo kodwa engathembekile yokubikezela ukuziphatha kokumboza," futhi iphawula ukuthi lo mkhuba awukaze wenzelwe ukuqhathanisa amasampula aqhutshwa emakamelweni ahlukene ngaphansi kwezimo ezifanayo. Kodwa ngisabona ama-RFQ athi kuphela "kudingeka ukuhlolwa kwe-salt spray," okunikeza umhlinzeki isheke elingenalutho: bakhetha amahora, bakhetha ukuhlolwa, bamemezela iphasi. Ukulungiswa akubizi lutho, futhi ngikubhala kuyo yonke i-RFQ engiyibuyekezayo: umthengi usetha umugqa wokwamukela, bese ilebhu igijimela kuwo.
Amapharamitha Egumbi Elihlanu Okumele Avele Ekhasini
Uma ngivula i-umbiko wokuhlolwa kokugqwala, Ngiya ngqo ebhulokini lesimo sokuhlola, ngoba ukugeleza kwenkungu kungaphindeka kuphela uma izinombolo ezinhlanu zibhalwe phansi. Ngokwemingcele yokusebenza ebhalwe yi-Isifinyezo sendlela ye-ASTM B117 ye-Cotec Labs, i-spray kasawoti engathathi hlangothi ehambisanayo ibamba isisombululo se-sodium chloride esingu-5% ku-pH 6.5–7.2, izinga lokushisa legumbi elingu-35°C ± 2°C, umswakama ongaba ngu-95% ± 5%, kanye nesilinganiso sokuxazulula inkungu esingu-1.0–2.0 mL ngehora endaweni engama-80 cm² yendawo yokuqoqwa, kanye nezibonelo ezithambekele ku-15–30° ukusuka phezulu. Uma umbiko ubonisa ubude besikhathi kanye nesithombe kuphela, angikwazi ukubona ukuthi i-spray ehambisanayo ivela kumshini wokomisa izinwele okhonjwe ebhakedeni.
| Ipharamitha | Inani elihambisanayo | Lokho engikumaka uma kulahlekile |
|---|---|---|
| Ukuhlushwa kukasawoti | 5% NaCl ngesisindo (isigaba sama-50 g/L) | Ukugxila okungalungile kushintsha i-kinetics yokugqwala; imiphumela ayifani |
| Isixazululo se-pH | 6.5–7.2 uma i-atomized ku-35°C | Inkungu ene-asidi (pH < 6.5) iwukuhlolwa okuhlukile, okunzima okuthathwa njengokungathathi hlangothi |
| Izinga lokushisa legumbi | 35°C ± 2°C | Izinga lokushisa eliphakeme lisheshisa ukuhlasela; "ukusebenza" okukhuphukile ngezindleko zomthengi |
| Izinga lokuxazululwa kwenkungu | 1.0–2.0 mL/ihora ngalinye ngama-80 cm² | Ukungagcwali kahle kuyindlela elula yokwenza sengathi usebenza amahora amaningi |
| Ukuqondiswa kwesampula | 15–30° ukusuka phezulu, akukho ukuthintana, akukho ukuvuza | Izibonelo ezilele phansi noma ezithintayo ziqoqa i-electrolyte kanye nokugqwala kusenesikhathi — noma sekwephuzile, uma zivikelwe |
Ngenxa yokuthi yonke yalezi zinhlaka ezinhlanu ishukumisa izinga lokugqwala, umbiko oshiya ngisho neyodwa yazo awukwazi ukuphinda ukhiqizwe ilebhu yesibili - futhi umphumela ongeke uphinde ukhiqizwe awukwazi ukuqinisekiswa.I-ASTM ngokwayo ixwayisa kuSigaba 3.3 ukuthi ukuguquguquka kuvela phakathi kwamakamelo enkungu ahlukene ngisho nangaphansi kwezimo ezifanayo, yingakho ingxenye efanayo idinga ukukopishwa okwanele. Iphansi lami lingamasampula amathathu ngokugijima ngakunye; isampula eyodwa ecwebezelisiwe ethathwe ngehora lama-96 ingitshela ngezithombe, hhayi ukukhiqizwa.
Amahora Akuwona Iminyaka — Ukufunda Umugqa Wesikhathi Ngokwethembeka
Ukufundwa kabi okubizayo kakhulu ekuqeqeshweni komhlinzeki ukuguqula amahora okufafaza usawoti abe iminyaka yesevisi. Akukho sici sokuguqulwa, futhi ekufundeni kwami idatha kuba kubi kakhulu uma ubheka kakhulu. Ucwaningo lokuxhumana kwensimu olushicilelwe yi-Uphiko locwaningo lwePresto GroupUlandele izingxenye ezine zezimboni kusukela ekamelweni kuya ekufakweni futhi wathola lokhu: i-compressor assembly efinyelela emahoreni angu-216 enkungwini ibonise ukugqwala kokuqala ensimini eminyakeni emi-5 eChennai egudle ugu; i-hot-dip galvanized anchor bolt efinyelela emahoreni angu-200 yahlala iminyaka engu-20 eMumbai; kanye ne-mild-steel bracket ephethe amahora angu-144 kuphela yahlala iminyaka emi-2 emoyeni ongcolile waseNew Delhi. Ngifunde lelo thebula ngendlela umthengi ngamunye okufanele athathe ngayo: amahora angu-200 athenge iminyaka engamashumi amabili edolobheni elilodwa, kuyilapho amahora angu-216 ethenge amahlanu kwelinye. I-Pearson coefficient kuwo wonke amasampula ensimbi yaphuma ku-+0.66 - isignali ewusizo yokukala, engekho eduze kwesibikezeli sokuphila - futhi yawa yaya ku-−0.16 ngesikhathi ingxenye edwetshiwe ingezwa.
| Isibonelo | Umphumela we-ASTM B117 | Ukugqwala kwensimu yokuqala | Indawo yasensimini |
|---|---|---|---|
| Ukuhlanganiswa kwe-compressor (i-MoS₂ embozwe) | Amahora angu-216 kuya ekugqwaleni okukhulu okubomvu | Iminyaka emi-5 | I-Coastal Chennai, 25–35°C, 65–85% RH |
| Ibhawodi ye-anchor efakwe ngogesi eshisayo | Amahora angu-200 kuya ekugqwaleni okukhulu okumhlophe | Iminyaka engama-20 | I-Mumbai, 25–33°C, 80–90% RH |
| Ibhulakhethi yensimbi ethambile embozwe ngophuphu | Amahora angu-144 kuya ekugqwaleni okukhulu okubomvu | iminyaka engu-2 | INew Delhi, ukungcola okuphezulu kwe-PM2.5/PM10 |
| Iphaneli elipendwe ngombala omnyama kaMatt | Kudlule amahora angu-432 | Iminyaka emi-5 (ukuqhekeka) | I-Pune yasemadolobheni, 40–65% RH |
Imboni ibilokhu ikusho lokhu ngokusobala amashumi eminyaka.Umagazini i-CoatingsTech we-American Coatings Associationibiza i-B117 ngokuthi “uphawu oluyisisekelo” oluneminyaka engu-86 ubudala lokulinganisa izinga — futhi ixwayisa ngokuthi abathengi “abazihlobanisa amahora nokwehluleka kwe-salt spray nokuphila komkhiqizo” bayakusebenzisa kabi, ngoba ukuvezwa kwangempela kwenezela i-UV, ukujikeleza okumanzi-komile, ukushintshashintsha kwezinga lokushisa, kanye nokungcola okungaveli nkungu eqhubekayo. Kuyo yonke imibiko edlula edeskini lami, amafasitela okuvezwa aqala emahoreni angu-24 kuya emahoreni angaphezu kuka-1,500 kuye ngokuthi kuchazwe kanjani — okukutshela ukuthi inombolo ithambile kangakanani.Ngenxa yokuthi ukugqwala komhlaba kubangelwa ukumelana nenhlabathi, imibhangqwana ye-galvanic, kanye nemisinga elahlekile kunenkungu ye-chloride, indondo yegumbi yamahora angu-500 ayisho lutho ngeminyaka engama-30-50 oyidingayo ku-electrode yomhlaba.
Ukulungiswa Kwesifanekiso: Lapho Imibiko Ebuthakathaka Ifihla Umzimba
Entongeni eboshwe ngethusi, ukuhlolwa kwe-corrosion forensics kunomusa ongavamile kumthengi — ngisho lokho kusukela eminyakeni yokufunda amasampula ahlulekile.Ngenxa yokuthi ithusi liyinsimbi enhle kakhulu kulokhu kubhangqa, ukugqwala okubomvu kungavela kuphela lapho insimbi ivezwe khona - ngakho imephu yokugqwala kusampula evivinyiwe iyi-X-ray eqondile lapho ungqimba lwethusi luphukile khona, lunezimbobo, noma luhlutshiwe.Yingakho ngiphatha amanothi okulungiselela njengesigaba sokuxilonga kakhulu kulo lonke umbiko. Ingabe induku ihlolwe njengoba injalo, iziphetho ezisikiwe zivele obala? Ingabe imicu kanye nengxenye yokushayela ivalwe nge-wax noma ngeteyipu? Ingabe umbhali wasika ijazi waze wafika enkabeni? Ukukhetha ngakunye kushintsha lokho okushiwo amahora.
Nansi indlela engifunda ngayo amalungiselelo amathathu engiwabona njalo. Induku esikiwe eneziphetho eziveziwe ihlola icala elibi kakhulu elidalwa yisifaki sakho kuyo yonke insimu esikiwe - ukugqwala okubomvu kwasekuqaleni emaphethelweni kulindeleke futhi akukuvimbeli uma ubuso obuyindilinga buhlala buhlanzekile. Induku eneziphetho ezivaliwe kanye nezintambo ihlola ijakethi uqobo; noma yikuphi ukugqwala okubomvu emgqonyeni manje kusho imigodi noma ukugoba ethusi elifakwe ngogesi, okuwukwehluleka kwenqubo yangempela. Futhi isampula ebhalwe phansi elinganiswe ngaphansi kwe-ISO 10289 - lapho isichazi se-Cotec Labs siphawula khona imiphumela ibikwa njengenombolo ye-Rp yokuvikela ukugqwala okubomvu kanye nenombolo ye-A yokubukeka - ihlola ukuqhekeka kwefilimu engaphansi kwefilimu, ikutshela ukuthi ukuklwebheka okusebenzayo kuba yibala noma isilonda sesakhiwo. Imininingwane yethu yomkhiqizo idinga ukuthi ukugoba kwethusi kuqhubeke ngokugcwele "ngaphandle kwemifantu, imigodi, imigodi," kanye nokugoba okungu-90° ku-radius engu-100 mm ngaphandle kokuphuka - ngoba ijakethi kumele iphile kokubili ekamelweni kanye nesando sokushayela.
Sebenzisa Noma Yimuphi Umbiko Womhlinzeki Ngalesi Sihloli Samaphuzu Ayisishiyagalombili
Lesi yisikrini ngqo engisisebenzisayo ngaphambi kokuthiukuqinisekiswa kwekhwalithi yenduku yomhlabathiIfayela lifinyelela kumakhasimende ethu. Maka ukuthi umbiko ophambi kwakho uquketheni ngempela — umhloli uwubeka ngendlela engingayenza.
Umbiko Wokuchela Ifulegi Elibomvu Wokubika Isifutho Sikasawoti
Lokho Engikubeka Igama Lethu Kuye Esikhundleni Sesithombe Segumbi
Isifutho sikasawoti sithola indawo yaso efayeleni lami lokuvunyelwa ngumhlinzeki njengesibuko sokuqhathanisa, hhayi njengesisekelo. Isisekelo yilokho engingakukala nsuku zonke zokukhiqiza esitshalweni sethu saseXinchang.izinduku zomhlaba ezimbozwe ngethusi, impikiswano yokugqwala iqala ngejakethi eqhubekayo eboshwe ngogesi okungenani engu-0.254 mm ku-≥99.95% ubumsulwa bethusi phezu kwensimbi engaphansi kwekhabhoni — isigaba sobukhulu bethuinduku yomhlaba engu-0.254 mm embozwe ngethusiUmugqa wakhiwe nxazonke. Ubukhulu buhlelwe ngokulinganisa i-micrometer ezingcezwini ezithathwe isampula kusuka kubhetshi ngayinye, ukunemba kubanjwa ngaphakathi kwe-1 mm ngemitha, amandla okudonsa ku-≥580 N/mm², futhi yonke intonga kumele isinde ekugobeni okungu-90° ku-radius engu-100 mm ngaphandle kokuphuka kwethusi noma ukulimala kwesibopho - ukuhlolwa okubamba amaphutha ejakethi igumbi lenkungu elikuthola sekwephuze kakhulu.
Kuyo yonke indawoizinduku zethusi eziboshiweububanzi — ububanzi obungu-14.2–25 mm, ubude obungu-1.2–3.0 m, izingcezu ezingu-50,000 ngenyanga — amarekhodi ebhetshi amboza ukujiya kwesendlalelo sethusi, ukunamathela, imiphumela yokugoba, kanye nokuqhubeka kweplati, kanye nakho konkeisigaba senduku yomhlabathiithunyelwa ngemibhalo yesistimu ye-ISO 9001 ngemuva kwayo. Uma ikhasimende licela ubufakazi bokufafazwa ngosawoti phezulu, ngiyakwamukela — kodwa ngiyakucaphuna ngokwethembeka: i-datapoint eqhathanisayo evela ku-defined run, ehambisana ne-batch metrology ebikezela impilo yokuklama yeminyaka engu-50 ngaphansi komhlaba. Uma indawo yakho igudle ugu noma inolaka lwamakhemikhali, sicele nomzila wokuhlola nge-cyclic; singathanda ukwenza isivivinyo esinzima kunokukubona uvuma esilula.
imibuzo ejwayelekile ukubuzwa
Induku yomhlabathi eboshwe ngethusi kufanele idlule amahora amangaki okufutha usawoti?
Akukho uphawu lokudlula olujwayelekile, ngoba i-ASTM B117 ayibeki lutho ngamabomu — isikhathi sokuchayeka kanye nemibandela yokwamukelwa kungokwencazelo yomthengi. Empeleni ngibona amahora angu-48-96 eceliwe ukuze kuhlolwe izimboni ezijwayelekile kanye namahora angamakhulu amaningana lapho abathengi befuna khona isango eliqhathaniswayo eliqinile. Indlela eqotho ukulungisa inqubo kuqala — isibonelo, akukho ukugqwala okubomvu ebusweni obuyindilinga emahoreni angu-96 aneziphetho ezivaliwe — bese ubamba wonke umhlinzeki ngendlela efanayo. Amahora abeka abahlinzeki kuphela; abakaze baqinisekise iminyaka.
Ingabe umphumela we-ASTM B117 ubikezela ukuthi induku izohlala isikhathi esingakanani ngaphansi komhlaba?
Cha, futhi indinganiso isho kanjalo ngokwayo: Isigaba 3.2 sithi ukubikezela ukusebenza ezindaweni zemvelo akuvamile ukuhlotshaniswa nemiphumela yokufuthwa kukasawoti esetshenziswa njengedatha ezimele. Ama-electrode angcwatshwe abhekene nokumelana nenhlabathi, ukuhlanganiswa kwe-galvanic, i-gradient yomswakama, kanye nemisinga elahlekile — okungekho kuyo inkungu ye-chloride engu-35°C ephindaphindayo. Idatha yasensimini isekela lesi sixwayiso: amacala aqoshiwe abonisa amahora angama-200 egumbi ahambisana neminyaka engama-20 yasensimini edolobheni elilodwa kanye namahora angama-216 kuya eminyakeni emi-5 kuphela kwelinye. Impilo yangaphansi komhlaba iphikiswana kusukela ekujiyeni kwengqimba yethusi, ukuqhubeka, kanye nezimo zenhlabathi, hhayi amahora enkungu.
Uyini umehluko phakathi kwe-ASTM B117 ne-ISO 9227 ngezinduku zomhlaba?
Ngokusebenza kahle bangamawele: bobabili bachaza inkungu ye-NaCl engu-5% engathathi hlangothi ku-35°C ene-pH engu-6.5–7.2, kanti umbiko obhalelwe omunye ngokuvamile ungafundeka komunye. I-ASTM B117 ibusa imininingwane yaseNyakatho Melika; i-ISO 9227 ibusa eyaseYurophu neyamazwe ngamazwe, kanti i-ISO 10289 inikeza ulimi lwesilinganiso se-Rp/A lwemiphumela. Engikufunayo umbiko oqamba indinganiso eyodwa, uyilandele ngokuphelele, futhi uthi indlela yokuhlola - i-hybrid "ehlolwe ngomugqa ngamunye we-ASTM/ISO" engenazo izilinganiso iyifulegi elibomvu, hhayi ukuvumelana.
Umbiko womhlinzeki uthi “akukho ukugqwala okubomvu emahoreni angama-96.” Lokho kuye kwafakazelani ngempela?
Kuphela lokho okulungiselelwe okuvumele ukuthi kukufakazele. Uma iziphetho ezisikiwe kanye nezintambo zivaliwe, kukhombisa ukuthi ijazi beliqhubeka kulezo zibonelo amahora angama-96 - umphumela wangempela kodwa ophansi, njengoba amahora angama-96 kuyisikrini esincane sezimboni. Uma iziphetho zivezwe, lindela ukugqwala kokuphela ngisho nasezindongeni ezinhle, futhi ukungabikho kwayo kungaba okusolisayo. Noma ngabe yikuphi, isimangalo siyaqhathaniswa: sikuvumela ukuthi ulinganise lo mhlinzeki nomunye ngesikhathi esifanayo. Lokho okungakufakazanga impilo yenkonzo engaphansi komhlaba, ukuqina kwe-batch-to-batch, noma ukusebenza enhlabathini yakho - lokho kudinga amarekhodi okujiya futhi, ezindaweni ezinzima, ukuhlolwa okujikelezayo.
Ingabe kufanele ngifune ukuhlolwa kokufuthwa kukasawoti kuwo wonke amaqoqo okukhiqiza?
Ngeke ngikwenze — futhi ngiqhuba ifektri. Ukugijima kwegumbi kuhamba kancane, futhi ukuhlolwa kwenkungu ngeqembu ngalinye kungangeza amasonto ngaphandle kokwengeza isiqinisekiso esifanele, ngoba isigaba sokuguquguquka se-B117 sixwayisa ukuthi ngisho namakamelo afanayo ngokwegama elilodwa awavumelani. Ubufakazi beqembu ngalinye obubamba ukugeleza kokukhiqiza kwangempela bushesha futhi buqondile: imephu ye-micrometer yobukhulu bethusi, ukunamathela kanye nokuhlolwa kokugoba endaweni engama-100 mm radius, kanye nokuhlolwa kokuqhubeka kokubona. Bhukha i-salt spray ukuze uthole iziqu kanye nokuqinisekiswa kabusha njalo - minyaka yonke, noma ngemva kwanoma yiluphi ushintsho lwenqubo - futhi uvumele i-metrology yansuku zonke ivikele amaqoqo aphakathi.
Yisiphi isitifiketi okufanele sibe naso ilabhorethri yokuhlola?
Funa ukugunyazwa kwe-ISO/IEC 17025 nge-salt spray ngaphakathi kobubanzi obushicilelwe belebhu — eShayina ngokuvamile kugunyazwe yi-CNAS, emhlabeni wonke noma yimuphi umkhandlu osayina i-ILAC. Bese wenza ukuqinisekiswa kwemizuzu emibili engikutholayo ukuthi abathengi abaningi bayakweqa: xhumana nelebhu ngqo nenombolo yombiko bese uqinisekisa ukuthi ikhiphe lowo mbhalo waleyo ncazelo yesampula. Inombolo yombiko eqinisekisiwe evela elebhu egunyaziwe ibaluleke kakhulu kune-PDF enhle, futhi noma yimuphi umhlinzeki oqiniseka ngokuhlolwa kwakhe uzokusiza ukuthi uyihlole.
Ingabe umbiko we-B117 wanele esiteshini esincane esisogwini noma endaweni yokucwenga?
Hhayi zodwa. Izimo zasogwini nezezimboni zengeza ukujikeleza okumanzi okomile, i-UV, kanye nekhemikhali yokungcola engathintwa yinkungu eqhubekayo, yingakho isibuyekezo se-American Coatings Association sincoma ukwandisa ukufuthwa kukasawoti ongathathi hlangothi ngezindlela ezijikelezayo — izinhlobo ze-ASTM G85, i-SWAAT, noma i-prohesion — kanye ne-ISO 12944-9 ukuze kuvezwe emoyeni. Ngengxenye efihliwe, hlanganisa ukuhlolwa komoya nedatha yokumelana nenhlabathi kanye nemibhalo yobukhulu bensimbi yethusi. Uma indawo yakho ingaphakathi komoya ogcwele usawoti ogwini lolwandle, sitshele imvelo ku-RFQ futhi sizophakamisa indlela enzima yokuhlola nawe.
Ubuyekeza ifayela lokugqwala lomhlinzeki njengamanje?
