Kwikota ephelileyo umthengi undithumelele umntu okhuphisana nayeuvavanyo lokutshiza ityuwa yentonga yomhlabaingxelo kwaye ndabuza umbuzo omnye: “Ingaba iiyure ezingama-96 zilungile?” Impendulo yam yammangalisa: inombolo yayiyeyona ingundoqo kwiphepha. I-ASTM B117 yindlela yokusebenza kwegumbi - ixelela ilabhoratri indlela yokusebenzisa inkungu, kwaye iyala ngokucacileyo ukukuxelela ukuba isiphumo sithetha ukuthini ubomi benkonzo. Okugqiba ngokwenene ukuba loo ngxelo iyayikhusela na iprojekthi yakho yinto yonke ejikeleze inani leeyure: iiparameter ezintlanu zegumbi, ukulungiswa kwesampuli, indlela yovavanyo, inani eliphindaphindwayo, kunye nokuqinisekiswa kwelabhoratri. Ndiyayamkela okanye ndiyayigatya ubungqina bokugqwala kwababoneleli inyanga nenyanga, kwaye esi sikhokelo sisikhokelo sokufunda esichanekileyo endisisebenzisayo - ngamanani afanele avele kwingxelo ethembekileyo, ubungqina obubhaliweyo bokuba iiyure zokutshiza ityuwa azihambelani neminyaka, kunye nesixhobo sokujonga iflegi ebomvu esisebenzisanayo onokusisebenzisa kuyo nayiphi na iPDF umthengisi akuthumelela yona.
TL;DR — Funda Ingxelo kule Nkqubo
- I-ASTM B117 ichaza kuphela imeko-bume yovavanyo, ayiphumeleli/ingaphumeleli: umgangatho ngokwawo uthi “awuchazi uhlobo lwesampuli yovavanyo okanye amaxesha okuvezwa… okanye ingcaciso emele inikwe iziphumo” — ngoko ke nayiphi na ingxelo engenazo iikhrayitheriya zokwamkelwa ezivunyiweyo ngumthengi ayiphelelanga ngoyilo.
- Ingxelo ethembekileyo ithi iiparameter ezintlanu zegumbi: isisombululo se-5% se-NaCl, 35°C ± 2°C, i-pH 6.5–7.2, izinga lokuhlala kwenkungu eliyi-1.0–2.0 mL/h kwi-80 cm² nganye, kunye neesampuli kwi-15–30° ukusuka phezulu; iparameter engekhoyo ithetha ukuba ukubaleka akunakuphinda kuphindwe.
- Amaxesha okutshiza ityuwa awaguquki abe yiminyaka yenkonzo: iseti yedatha yendawo ebhaliweyo ibonisa isampuli yeeyure ezingama-200 ehlala iminyaka engama-20 eMumbai ngelixa isampuli yeeyure ezili-144 yasilela kwiminyaka emi-2 eNew Delhi - ulwalamano lwePearson lwe-+0.66 kuphela naphakathi kwamacandelo esinyithi afanayo.
- Kwintonga yomhlaba ebotshelelwe ngobhedu, umhlwa obomvu unokuvela kuphela kwintsimbi eveziweyo, ngoko ke apho umhlwa uvela khona — iziphelo ezisikiweyo, imisonto, imigca yokubhala — ikuxelela ngqo apho umaleko wobhedu usilele khona, yiyo loo nto amanqaku okulungiselela isampuli ebaluleke ngaphezu kweeyure zentloko.
- Isixhobo sethu esinamanqaku asi-8 esingezantsi sifumana amanqaku kwingxelo yomthengisi ngemizuzu emibini; nantoni na engekhoyo kwiiparameter zegumbi, indlela yovavanyo, okanye ukuqinisekiswa kwelebhu kubuyela emva ngemibuzo ngaphambi kokuba kuvunywe.
Oko i-ASTM B117 iyiyo ngokwenene - iCandelo leMicimbi, kungekhona isigwebo
Into yokuqala endiyijongayo kuyo nayiphi naIntonga yomhlaba ye-ASTM B117Ingxelo kukuba ingaba umthengisi uyayiqonda na into ayiphetheyo. Isihloko esipheleleyo se-B117 yi-Standard Practice for Operating Salt Spray (Fog) Apparatus, kwaye igama elisetyenziswayo lithetha “ukusebenza.”Isishwankathelo se-ASTM International se-B117-19ICandelo 1.2 lithi kwiCandelo 1.2 le ndlela yokusebenza “ayichazi uhlobo lwesampuli yovavanyo okanye amaxesha okuvezwa ekufuneka asetyenziswe kwimveliso ethile, okanye ingcaciso ekufuneka inikwe iziphumo.” Icandelo 3.2 liqhubeka lithi: “Ukuqikelelwa kokusebenza kwiindawo zendalo akusoloko kunxulunyaniswa neziphumo zokutshizwa ngetyuwa xa zisetyenziswa njengedatha ezimeleyo.”Ngenxa yokuba umgangatho uchaza kuphela inkungu kwaye uyala ukuchaza umgca wokugqibela, ingxelo ebonisa iiyure ezingenazo iikhrayitheriya zokwamkelwa ezivunyiweyo ngumthengi ayisiyo siphumo sovavanyo - yingxelo yemozulu evela ngaphakathi ebhokisini.
Oku akusiyonto ingaqhelekanga, kwaye andingomntu ndedwa okutshoyo.Iphephandaba lobuchwephesha likaSherwin-Williams malunga nemida ye-B117icaphula iphepha le-SSPC lika-1995 eligqiba ngelithi le ndlela inika "indlela ekhawulezayo kodwa engathembekanga yokuqikelela indlela yokugquma," kwaye iphawula ukuba le ndlela ayizange yenzelwe ukuthelekisa iisampulu eziqhutywa kumagumbi ahlukeneyo phantsi kweemeko ezifanayo. Kodwa ndisabona ii-RFQ ezithi kuphela "kufuneka uvavanyo lokutshiza ityuwa," ezinika umthengisi itshekhi engenanto: bakhetha iiyure, bakhetha uvavanyo, babhengeza ipasi. Ukulungiswa akubizi mali, kwaye ndiyibhala kuyo yonke i-RFQ endiyiphononongayo: umthengi ubeka umgca wokwamkelwa, kwaye ilebhu ibaleka kuyo.
IiParameters zeChamber ezintlanu ezimele zivele kwiphepha
Xa ndivula iingxelo yovavanyo lokugqwala, Ndiya ngqo kwibhloko yemeko yovavanyo, kuba ukubaleka kwenkungu kunokuphinda kuvele kuphela ukuba amanani amahlanu abhalwe phantsi. Ngokweeparamitha zokusebenza ezibhalwe nguIsishwankathelo sendlela ye-ASTM B117 yeCotec Labs, i-spray yetyuwa engathathi hlangothi ehambelanayo ibamba isisombululo se-sodium chloride se-5% kwi-pH 6.5–7.2, ubushushu begumbi obuyi-35°C ± 2°C, umswakama ojikeleze i-95% ± 5%, kunye nesantya sokulungiswa kwenkungu esiyi-1.0–2.0 mL ngeyure kwi-80 cm² yendawo yokuqokelela, kunye neesampuli ezithambekele kwi-15–30° ukusuka phezulu. Ukuba ingxelo ibonisa ubude kunye nefoto kuphela, andinakwazi ukubona i-run ehambelanayo evela kwi-hairdryer ekhombe kwibhakethi.
| Ipharamitha | Ixabiso elihambelanayo | Oko ndikuphawuleyo ukuba akukho |
|---|---|---|
| Uxinzelelo lwetyuwa | I-5% yeNaCl ngokobunzima (udidi lwe-50 g/L) | Uxinzelelo olungalunganga lutshintsha i-corrosion kinetics; iziphumo azinakuthelekiswa |
| Isisombululo se-pH | 6.5–7.2 xa i-atomized kwi-35°C | Inkungu ene-asidi (pH < 6.5) luvavanyo olwahlukileyo nolunzima oluthi luthathwe njengolungathathi cala |
| Ubushushu begumbi | 35°C ± 2°C | Ubushushu obuphezulu bukhawulezisa uhlaselo; "ukusebenza" okuphezulu ngeendleko zomthengi |
| Izinga lokuhlaliswa kwenkungu | 1.0–2.0 mL/h kwi-80 cm² nganye | Ukugquma ngaphantsi kwenkungu yeyona ndlela ilula yokwenza ngathi usebenza iiyure ezininzi |
| Ukujongwa kwemizekelo | 15–30° ukusuka phezulu, akukho kudibana, akukho drip-over | Iisampuli ezilele phantsi okanye ezichukumisayo ziqokelela i-electrolyte kunye nomhlwa kwangethuba — okanye kade, ukuba zikhuselekile |
Ngenxa yokuba nganye kwezi parameter zintlanu ishukumisa izinga lokugqwala, ingxelo eshiya nenye yazo ayinakuphindwa kwakhona yilabhoratri yesibini - kwaye isiphumo esingenakuphindwa asinakuqinisekiswa.I-ASTM ngokwayo ilumkisa kwiCandelo 3.3 ukuba umahluko uyabonakala phakathi kwamagumbi ahlukeneyo enkungu naphantsi kweemeko ezifanayo, yiyo loo nto eli candelo linye lifuna iikopi ezaneleyo. Umgangatho wam ziisampuli ezintathu ngomdyarho ngamnye; isampuli enye ecociweyo efotwe kwiyure yama-96 indixelela ngemifanekiso, hayi imveliso.
Iiyure Azingominyaka — Ukufunda Umgca Wobude Ngokunyaniseka
Eyona nto ibiza kakhulu ekufundeni kakubi kwiziqinisekiso zomthengisi kukuguqula iiyure zokutshiza ityuwa zibe yiminyaka yenkonzo. Akukho nto ibangela ukuguqulwa, kwaye ekufundeni kwam idatha kuya kuba kubi ngakumbi xa ujongeka unzima. Uphononongo lokunxibelelana kwentsimi olupapashwe nguIcandelo lophando lePresto Groupulandelise iindawo ezine zoshishino ukusuka kwigumbi ukuya ekufakweni waza wafumanisa oku: indibano yecompressor efikelela kwiiyure ezingama-216 kwinkungu ibonise ukubola kokuqala kwentsimi kwiminyaka emi-5 eChennai eselunxwemeni; ibholthi ye-anchor eshushu efikelela kwiiyure ezingama-200 yahlala iminyaka engama-20 eMumbai; kwaye ibracket yentsimbi ethambileyo elawula iiyure ezili-144 kuphela isahlala iminyaka emi-2 emoyeni ongcolileyo waseNew Delhi. Ndiyifundile loo tafile ngendlela wonke umthengi afanele ayenze ngayo: iiyure ezingama-200 zithenge iminyaka engamashumi amabini kwisixeko esinye, ngelixa iiyure ezingama-216 zithenge ezintlanu kwesinye. I-Pearson coefficient kuzo zonke iisampuli zesinyithi iphume kwi-+0.66 - uphawu oluluncedo lokubeka, akukho ndawo ikufutshane nesandulela sobomi - kwaye yawa yaya kwi-−0.16 ngomzuzu wokongezwa kwenxalenye epeyintiweyo.
| Isampuli | Isiphumo se-ASTM B117 | Ukubola kwentsimi yokuqala | Indawo engqongileyo yasentsimini |
|---|---|---|---|
| Indibano yesiguquli (i-MoS₂ egqunywe nge-camera) | Iiyure ezingama-216 ukuya kumhlwa obomvu omkhulu | Iminyaka emi-5 | I-Coastal Chennai, 25–35°C, 65–85% RH |
| I-hot-dip galvanized anchor bolt | Iiyure ezingama-200 ukuya kumhlwa omhlophe omkhulu | Iminyaka engama-20 | Mumbai, 25-33 ° C, 80-90% RH |
| Isibiyeli sesinyithi esithambileyo esigqunywe ngumgubo | Iiyure ezili-144 ukuya kumhlwa obomvu omkhulu | iminyaka eyi-2 | INew Delhi, ungcoliseko oluphezulu lwe-PM2.5/PM10 |
| Iphaneli emnyama epeyintwe nguMatt | Idlule iiyure ezingama-432 | Iminyaka emi-5 (ukuqhekeka) | IPune yasezidolophini, 40–65% RH |
Eli shishini lithethe oku ngokucacileyo kangangeminyaka emininzi.Imagazini iCoatingsTech ye-American Coatings Associationibiza i-B117 "njengomlinganiselo osisiseko" oneminyaka engama-86 ubudala wokulinganisa udidi - kwaye ilumkisa ukuba abathengi "abazidibanisa iiyure zabo kunye nokusilela kwe-salt spray nobomi bemveliso" bayisebenzisa gwenxa, kuba ukuvezwa kokwenyani kongeza i-UV, ukujikeleza okumanzi-omileyo, utshintsho lobushushu, kunye nokungcola okungaveliyo inkungu eqhubekayo. Kuzo zonke iingxelo ezidlula edesikeni yam, iifestile zokuvezwa zisebenza ukusuka kwiiyure ezingama-24 ukuya kwiiyure ezingaphezu kwe-1,500 kuxhomekeke kwinkcazo - ekuxelela ukuba inani lithambile kangakanani.Ngenxa yokuba ukugqwala komhlaba kubangelwa kukunganyamezelani komhlaba, imibhangqwana ye-galvanic, kunye nemisinga elahlekileyo endaweni yenkungu ye-chloride, imbasa yegumbi leeyure ezingama-500 ayithethi nto malunga neminyaka engama-30-50 oyifunayo kwi-electrode yomhlaba.
Ukulungiswa kweMifanekiso: Apho Iingxelo Ezibuthathaka Zifihla Umzimba
Kwintonga ebotshelelwe ngobhedu, i-corrosion forensics inobubele obungaqhelekanga kumthengi — nditsho oko kwiminyaka yokufunda iisampuli ezingaphumelelanga.Ngenxa yokuba ubhedu luyinto ebalulekileyo kwesi sibini, umhlwa obomvu unokubonakala kuphela apho intsimbi ivezwe khona - ngoko ke imaphu yomhlwa kwisampuli evavanyiweyo yi-X-ray ethe ngqo apho umaleko wobhedu waphukile khona, unemingxuma, okanye waxotyulwa khona.Yiyo loo nto ndithatha amanqaku okulungiselela njengesiqendu esiphambili sokuxilongwa kuyo yonke ingxelo. Ngaba intonga ivavanyiwe njengoko injalo, iziphelo ezisikiweyo zityhilekile? Ngaba imisonto kunye nesiphelo sokuqhuba zitywinwe ngewax okanye ngeteyipu? Ngaba umbhali unqumle ijakethi ukuya embilinini? Ukhetho ngalunye lutshintsha oko kuboniswa ziiyure.
Nantsi indlela endifunda ngayo amalungiselelo amathathu endiwabona rhoqo. Intonga esikiweyo eneziphelo eziveziweyo ivavanya imeko embi kakhulu edalwa ngumfaki wakho kuyo yonke indawo esikiweyo - umhlwa obomvu ekuqaleni eziphelweni kulindeleke kwaye ayikuthinteli ukuba umphezulu osicaba uhlala ucocekile. Intonga eneziphelo ezivaliweyo kunye nemisonto ivavanya ijakethi ngokwayo; naluphi na umhlwa obomvu kwibhareli ngoku uthetha imingxunya okanye ukubola kwi-electroplated copper, oku kukusilela kwenkqubo yokwenyani. Kwaye isampuli ebhalwe phantsi kwe-ISO 10289 - apho inkcazo yeCotec Labs iphawula iziphumo zixelwa njengenani le-Rp lokukhusela umhlwa obomvu kunye nenani le-A lokubonakala - ivavanya ukuqhekeka kwefilimu engaphantsi, ikuxelela ukuba ingaba umkrwelo osebenzayo uba libala okanye inxeba lesakhiwo. Inkcazo yemveliso yethu ifuna ukuba i-copper cladding iqhubeke ngokupheleleyo "ngaphandle kwemikrwelo, imingxunya, imingxunya," kunye nokugoba kwe-90° kwi-radius ye-100 mm ngaphandle kokuqhekeka - kuba kanye ijakethi kufuneka iphile kwigumbi nakwisando sokuqhuba.
Sebenzisa nayiphi na ingxelo yomthengisi ngale 8-Point Checker
Le yisikrini endisisebenzisayo ngaphambi kokubaukuqinisekiswa komgangatho wentonga yomhlabaIfayile ifikelela kubathengi bethu. Phawula ukuba ingxelo ephambi kwakho iqulethe ntoni na ngokwenene — umhloli uyinika amanqaku ngendlela endiya kwenza ngayo.
Ingxelo yeSpray yeTyuwa, isiHloli seFlagi eBomvu
Oko Ndibeka Igama Lethu Kuyo Endaweni Yefoto Yegumbi
I-salty spray ifumana indawo yayo kwifayile yam yokuvunywa ngumthengisi njengesikrini sokuthelekisa, kungekhona njengesiseko. Isiseko yiloo nto ndinokuyilinganisa yonke imihla yemveliso kwisityalo sethu saseXinchang.iintonga zomhlaba ezigqunywe ngobhedu, impikiswano yokubola iqala ngejakethi eqhubekekayo ene-electroplated ubuncinane eyi-0.254 mm kwi-≥99.95% yobumsulwa bobhedu phezu kwesiseko sentsimbi esinekhabhoni ephantsi — udidi lobukhulu bethuintonga yomhlaba eyi-0.254 mm egqunywe ngobheduUmgca wakhiwe ngeenxa zonke. Ubukhulu bumepulwe ngokulinganisa i-micrometer kwiziqwenga ezithathwe kwisampuli nganye, ukuthe tye kubanjwa ngaphakathi kwe-1 mm ngemitha nganye, amandla okutsalwa kwi-≥580 N/mm², kwaye intonga nganye kufuneka isinde ekugobeni kwe-90° kwi-radius ye-100 mm ngaphandle kokuqhekeka kobhedu okanye umonakalo webhondi - uvavanyo olubamba iziphene zejakethi olufunyanwa luludala kakhulu.
Kuyo yonke indawoiintonga ezibotshelelweyo zobheduuluhlu — ububanzi obuyi-14.2–25 mm, ubude obuyi-1.2–3.0 m, iziqwenga ezingama-50,000 ngenyanga — iirekhodi zebhetshi zigubungela ubukhulu bomaleko wobhedu, ukunamathela, iziphumo zokugoba, kunye nokuqhubeka kweplati, kunye nayo yonke intoudidi lwentonga yomhlabaithunyelwa nge-ISO 9001 system documentation ngasemva kwayo. Xa umthengi ecela ubungqina bokutshiza ityuwa phezulu, ndiyakwamkela — kodwa ndiyicaphula ngokunyaniseka: i-datapoint ethelekisayo evela kuluhlu oluchaziweyo, oludibene ne-batch metrology eqikelela ubomi boyilo beminyaka engama-50 phantsi komhlaba. Ukuba indawo yakho ilunxwemeni okanye inamandla ekhemikhali, sicele indlela yovavanyo olujikelezayo; singathanda ukuqhuba uvavanyo olunzima kunokuba sikubone uvuma olulula.
Imibuzo ebuzwa qho
Zingaphi iiyure ekufuneka intonga yokugalela ebotshelelwe ngobhedu idlule kuzo?
Akukho phawu lokupasa oluqhelekileyo, kuba i-ASTM B117 ayibeki ngabom - ubude bexesha lokuvezwa kunye nemigangatho yokwamkelwa zezomthengi. Enyanisweni ndibona iiyure ezingama-48-96 eziceliweyo zokuhlolwa ngokubanzi kwemizi-mveliso kunye neeyure ezingamakhulu apho abathengi bafuna isango eliqatha lokuthelekisa. Indlela enyanisekileyo kukulungisa umlinganiselo kuqala - umzekelo, akukho mhlwa obomvu kumphezulu osilinda kwiiyure ezingama-96 ezineziphelo ezivaliweyo - emva koko ubambe wonke umthengisi ngendlela efanayo. Iiyure zibeka ababoneleli kuphela; abaze baqinisekise iminyaka.
Ngaba iziphumo ze-ASTM B117 zixela kwangaphambili ukuba intonga ihlala ixesha elingakanani phantsi komhlaba?
Hayi, kwaye umgangatho utsho njalo: Icandelo 3.2 lithi ukuqikelela ukusebenza kwiindawo zendalo akuqhelekanga ukuba kudityaniswe neziphumo zokutshizwa ngetyuwa ezisetyenziswa njengedatha ezimeleyo. Ii-electrode ezingcwatyiweyo zijongene nokuchasana nomhlaba, ukudibana kwe-galvanic, i-moisture gradients, kunye ne-stray currents - akukho nanye kuzo evelisa inkungu ye-chloride engama-35°C. Idatha yasentsimini ixhasa esi silumkiso: iimeko ezibhaliweyo zibonisa iiyure ezingama-200 zegumbi ezihambelana neminyaka engama-20 yasentsimini kwisixeko esinye kunye neeyure ezingama-216 ukuya kwiminyaka emi-5 kuphela kwesinye. Ubomi obungaphantsi komhlaba buphikisana ukusuka kubukhulu bomaleko wobhedu, ukuqhubeka, kunye neemeko zomhlaba, kungekhona iiyure zenkungu.
Yintoni umahluko phakathi kwe-ASTM B117 kunye ne-ISO 9227 kwi-earth rods?
Ngokwahlukileyo, bangamawele: bobabini bachaza i-5% ye-NaCl inkungu engathathi cala kwi-35°C ene-pH 6.5–7.2, kwaye ingxelo ebhalelwe enye iqhele ukufundeka ngokuchasene nenye. I-ASTM B117 ilawula iinkcukacha zaseMntla Melika; i-ISO 9227 ilawula ezaseYurophu nezamazwe ngamazwe, apho i-ISO 10289 inika ulwimi lokulinganisa lwe-Rp/A kwiziphumo. Endikufunayo yingxelo echaza umgangatho omnye, iwulandele ngokupheleleyo, kwaye ichaza indlela yovavanyo - umgca oxutyiweyo "ovavanyiweyo nge-ASTM/ISO" ongenazo iiparameters yiflegi ebomvu, ayisiyonto yokuvumelana.
Ingxelo yomthengisi ithi “akukho mhlwa obomvu kwiiyure ezingama-96.” Oko kuye kwabonisa ntoni ngokwenene?
Kuphela koko ukulungiswa okuvumele ukuba kungqine. Ukuba iziphelo ezisikiweyo kunye nemisonto zivaliwe, kubonisa ukuba ijakethi ibiqhubeka kuloo mizekelo iiyure ezingama-96 - isiphumo sokwenyani kodwa esincinci, kuba iiyure ezingama-96 sisikrini esilula semizi-mveliso. Ukuba iziphelo zivele, lindela ukugqwala kokuphela nokuba kwiintonga ezilungileyo, kwaye ukungabikho kwayo kuya kukrokrela. Nokuba yeyiphi na indlela, ibango liyathelekiswa: likuvumela ukuba ubeke lo mthengisi kwelinye icala ngexesha elifanayo. Into engakhange ibonakalise bubomi benkonzo phantsi komhlaba, ukuhambelana kwebhetshi ukuya kwelinye, okanye ukusebenza emhlabeni wakho - ezo zifuna iirekhodi zobukhulu kwaye, kwiindawo ezinzima, uvavanyo olujikelezayo.
Ngaba kufuneka ndifune uvavanyo lokutshiza ityuwa kwibhetshi nganye yemveliso?
Andiyi kuyenza loo nto — kwaye ndiqhuba umzi-mveliso. Ukuqhuba kwegumbi kuhamba kancinci, kwaye uvavanyo lwenkungu ngeqela ngalinye lunokongeza iiveki ngaphandle kokongeza isiqinisekiso esifanelekileyo, kuba icandelo lokuguquguquka kwe-B117 lilumkisa ukuba kwanegumbi elifanayo ngokwalo alivumelani. Ubungqina beqela ngalinye obubamba ukushukuma kwemveliso yokwenyani bukhawuleza kwaye buthe ngqo ngakumbi: imaphu ye-micrometer yobukhulu bekopolo, uvavanyo lokunamathela kunye nokugoba kwi-radius ye-100 mm, kunye nokuhlolwa kokuqhubeka kokubona. Gcina i-salt spray ukuze ufumane isiqinisekiso kunye nokuqinisekiswa kwakhona rhoqo — minyaka le, okanye emva kwayo nayiphi na inguqu yenkqubo — kwaye vumela i-metrology yemihla ngemihla ikhusele iibhetshi eziphakathi.
Yeyiphi imvume ekufuneka ilabhoratri yovavanyo ibe nayo?
Khangela uqinisekiso lwe-ISO/IEC 17025 ngetyuwa etshizwayo ngaphakathi kwecandelo elipapashwe yilebhu — eTshayina idla ngokuqinisekiswa yi-CNAS, kwihlabathi liphela naliphi na iqumrhu elisayine i-ILAC. Emva koko yenza uqinisekiso lwemizuzu emibini endifumana uninzi lwabathengi lungalufumani: nxibelelana nelebhu ngokuthe ngqo ngenombolo yengxelo kwaye uqinisekise ukuba ikhuphe olo xwebhu lwenkcazo yesampuli. Inombolo yengxelo eqinisekisiweyo evela kwilebhu eqinisekisiweyo ixabisa ngaphezu kwePDF entle, kwaye nawuphi na umthengisi oqinisekileyo ngovavanyo lwakhe uya kukunceda uyijonge.
Ingaba ingxelo ye-B117 yanele na kwisitishi esingaphantsi konxweme okanye kwindawo yokuhluza?
Hayi zodwa. Imozulu eselunxwemeni nakwimizi-mveliso yongeza ukujikeleza okumanzi-omileyo, i-UV, kunye nekhemistri yongcoliseko engenakuchukunyiswa yinkungu eqhubekayo, yiyo loo nto uphononongo lwe-American Coatings Association lucebisa ukongeza i-neutral salt spray ngeendlela ze-cyclic - i-ASTM G85 variants, i-SWAAT, okanye i-prohesion - kunye ne-ISO 12944-9 yokuvezwa emoyeni. Kwindawo efihliweyo, dibanisa uvavanyo lomoya kunye nedatha yokumelana nomhlaba kunye noxwebhu lobukhulu bomaleko wobhedu wentonga. Ukuba indawo yakho ikwindawo enomoya ogcwele ityuwa elunxwemeni, sixelele okusingqongileyo kwi-RFQ kwaye siya kukucebisa indlela enzima yovavanyo nawe.
Uphonononga ifayile yomthengisi yokugqwala ngoku?
Ndithumelele ingxelo — ndiza kusebenzisa isikrini esifanayo seenqaku ezisi-8 kuyo ndize ndikuxelele kungekapheli usuku olunye lokusebenza ukuba ingqina ntoni, ifihla ntoni, kwaye ucele ntoni ngokulandelayo.
