Thaum lub sij hawm kev tsim kho tshwj xeeb, txheej txheej txheej txheem txheej txheem thiab kev ntsuas los xyuas kom meej qhov zoo ntawm cov txheej txheem tiv thaiv corrosion yuav tsum tau npaj raws li cov qauv ntawm cov kab lus tiv thaiv corrosion.
Cov xwm txheej ib puag ncig thaum lub sijhawm thov yuav tsum ua raws li cov lus qhia. Nyob rau hauv cov ntaub ntawv ntawm nag, daus, pos huab, cua thiab xuab zeb thiab lwm yam kev nyab xeeb, lub qhib-cua kev tsim kho ntawm lub anti-corrosion txheej yuav tsum tau nres. Thaum qhov kev tsim kho ib puag ncig kub qis dua -5 degree lossis siab dua 40 degree, lossis qhov txheeb ze av noo siab dua 80 feem pua, nws tsis haum rau kev tsim kho. Cov txheej txheem tiv thaiv tsis zoo yuav tsum tau tiv thaiv los ntawm nag.
Yog hais tias xeb tshwm sim ntawm qhov chaw pretreatment thiab thawj primer, lub nto pretreatment yuav tsum tau rov kho dua ua ntej txheej. Rau cov thawv loj uas tsis tuaj yeem sandblasted nyob rau hauv ib hnub, lawv yuav tsum tau muab kaw kom tiv thaiv convection nrog cov pa sab nraud thiab ncua sij hawm rov qab xeb.
Chlorosulfonated polyethylene anticorrosive xim txheej tuaj yeem siv los ntawm airless spraying, airless spraying, txhuam los yog dov txheej thiab lwm yam kev tsim kho, nyob rau hauv kev txiav txim ntawm sab saum toj mus rau hauv qab txheej, lub txheej yuav tsum yog uniform, tsis muaj to, uas txheej txheej yuav tsum tau txiav txim siab. raws li txoj kev npaj tsim kho los tiv thaiv corrosion. Kev ua haujlwm txheej txheej yuav tsum ua raws li cov cai hauv qab no:
A. Thaum siv txoj kev txhuam hniav, daim ntawv thov quab yuam yog sib xws, thiab cov txhuam hniav yog pleev xim rau hauv tib qho kev taw qhia kom tsis txhob nto fluffing.
B. Thaum txau, rab phom txau yuav tsum txav mus rau ntawm qhov sib txawv ntawm qhov nrawm thiab ua kom lub nozzle perpendicular mus rau qhov chaw txau.
C. Thaum siv cov txheej txheem txheej txheej, lub nruas dipping cov ntaub ntawv yuav tsum tsis sib xws, tsis ntau dhau, lub zog yuav tsum tsis sib xws thaum dov, thiab yuav tsum tsis txhob loj dhau, thiab yuav tsum tswj kom muaj kev sib hloov ceev; Lub nruas yuav tsum tau dov nyob rau hauv tib txoj kev, thiab cov kev taw qhia yuav txawv rau txhua pass. Lub kaum sab xis, cov khoom siv thiab lwm qhov chaw uas tsis tuaj yeem coated los ntawm cov menyuam yuav tsum tau pleev xim nrog cov cuab yeej txhuam hniav.
Welds, fab thiab qhov tsis sib xws yuav tsum tau dipped nyob rau hauv cov xim los yog tus naj npawb ntawm daim ntawv thov hla yuav tsum tau nce.
Daim ntawv thov ncua sij hawm ntawm txhua cov xim yuav tsum tsis txhob ntau tshaj 24 teev, thiab cov xim tom ntej yuav tsum tau siv tom qab cov xim pleev xim rau saum npoo dries. Yog tias yav dhau los lacquer tau kho, tom qab lacquer tuaj yeem siv tau tsuas yog tom qab woolened. Tom qab siv cov topcoat zaum kawg, nws yuav tsum tau kho ntawm chav tsev kub 25 degree rau ntau tshaj 7 hnub ua ntej nws tuaj yeem siv tau. Yog tias qhov ntsuas kub qis dua 10 degree, nws yuav tsum tau kho ntau dua 10 hnub ua ntej nws tuaj yeem siv tau.
Thaum lub sij hawm tsim kho, cov yeeb yaj kiab ntub dej ntawm cov txheej yuav tsum tau ntsuas nyob rau hauv ntau qhov sib txawv, thiab cov viscosity ntawm txheej thiab txheej txheej txheej txheej yuav tsum tau hloov kho raws sij hawm kom ntseeg tau tias qhov kawg thickness ntawm cov txheej txheem tiv thaiv corrosion raws li tus qauv tsim. kev xav tau.
