1.Dab tsi yog tus yam ntxwv ntawm tus neeg saib xyuas nruab nrab tshwj xeeb rau xim -coated steel ntawv?
Cov mis mos: nruab nrab lossis me ntsis alkaline pH (feem ntau ntawm 7-10), nws yuav tsis corrode lossis yaj txheej.
Muaj zog detergency: muaj cov surfactants thiab emulsifiers kom zoo zom cov roj thiab av.
Yooj yim rau yaug: Tawm tsis muaj qhov seem tom qab ntxuav, tsis tso dej los yog cuam tshuam rau txheej txheej.
Kev tiv thaiv zoo heev: Qee cov khoom siv siab- kawg kuj muaj cov khoom siv tiv thaiv uas tsim cov yeeb yaj kiab tiv thaiv zoo heev tom qab ntxuav, txhim kho hydrophobicity.
2.Yuav siv nws li cas?
Dilute raws li cov khoom qhia.
Siv daim txhuam cev mos mos, tsis yog- ntaub npuag, lossis mos- txhuam txhuam txhuam hauv cov tshuaj ntxuav kom txhuam.
Yaug kom huv si nrog dej kom ntau (zoo dua yog siv lub tshuab nqus dej siab lossis lub hose qis).
Thaum kawg, so qhuav nrog ib daim ntaub huv, mos los yog cia cua qhuav.
3.Yog tsis muaj ib tug tshwj xeeb tu tus neeg saib xyuas, yuav ua li cas xaiv ib tug?
Cov khoom siv me me- lub hom phiaj ntxuav: xws li diluted neutral phaj xab npum lossis dej xab npum me me. Qhov no yog lwm txoj hauv kev nyab xeeb tshaj plaws hauv tsev. Ib txwm yaug kom huv si.
Muaj ntau txoj kev xaiv:
Cov tshuaj ntxuav hlau tshwj xeeb: xyuas kom meej cov lus qhia yog rau "cov xim pleev xim" lossis "prefabricated steel sheets".
Fat alcohol polyoxyethylene ether cleaners: ib qho nonnionic surfactant, zoo ntawm kev tshem cov roj thaum ua tau zoo.
4.Dab tsi yog txwv tsis pub los yog yuav tsum tau ceev faj heev?
Cov kua qaub muaj zog thiab alkalis: xws li hydrochloric acid, sulfuric acid, sodium hydroxide (caustic soda), thiab lwm yam. Cov no yuav ua rau cov txheej txheem sai sai rau saponify, hmoov, thiab tev.
Cov kuab tshuaj organic muaj zog: xws li thinner (txiv tsawb roj), acetone, xylene, roj av, thiab lwm yam. Cov kuab tshuaj no yuav yaj lossis ua kom cov organic coatings hnyav, ua rau tsis muaj qhov tsis zoo ntawm gloss, bubbling, thiab tev tawm.
Abrasive Cleaners: xws li cov hmoov txhuam hniav, hlau txhuam, thiab txhuam txhuam. Cov no yuav khawb qhov txheej txheej.
Cov roj stain muaj zog nrog cov khoom siv tsis paub: tshwj xeeb tshaj yog siv rau cov roj hauv chav ua noj hnyav, feem ntau tsis tshua muaj alkaline.
5.Dab tsi yog qee yam uas yuav tsum nco ntsoov?
Kuaj ua ntej daim ntawv thov: Ua ntej ib daim ntawv loj - nplai, ib txwm ua ib qho me me - ntsuas qhov ntsuas ntawm lub kaum sab xis lossis cov khoom seem kom paub meej tias nws yuav tsis cuam tshuam rau txheej txheej (tsis muaj npuas, tsis muaj gloss, tsis muaj xim).
Ntxuav tam sim ntawd: Cov roj stains ntev dua, lawv nyuaj dua los ntxuav thiab lawv tuaj yeem nkag mus rau txheej txheej.
Hu rau cov chaw tsim khoom: Txoj hauv kev nyab xeeb tshaj plaws yog sab laj nrog koj ua ntej -coated coil chaw tsim khoom lossis tus neeg muag khoom. Lawv muaj kev nkag siab zoo tshaj plaws ntawm cov yam ntxwv ntawm cov txheej txheem ntawm lawv cov khoom thiab tuaj yeem muab cov lus qhia zoo tshaj plaws los ntxuav, thiab tseem tuaj yeem pom zoo lossis muab cov tshuaj ntxuav kom zoo.
