Tig qhov kev cia ntawm cov kav dej los tiv thaiv corrosion, Kuv ntseeg tias ntau tus neeg muaj kev tsis ntseeg hauv thaj chaw no. Cia peb saib ntawm qhov khaws cia ntawm cov kav dej tiv thaiv corrosion.
1. Kev nkag mus thiab sab nrauv ntawm cov kav dej tiv thaiv corrosion yuav tsum tau kuaj xyuas zoo li no:
①Ib lub hauv paus tshuaj xyuas kom ntseeg tau tias qhov chaw ntawm cov txheej polyethylene yog du thiab du. Tsis muaj npuas tsaus, tshuaj loog, folds, thiab tawg tag nrho. Cov xim tag nrho xav tau sib npaug. Qhov saum npoo ntawm cov yeeb nkab yuav tsum tsis txhob muaj xeb ntau dhau.
② Lub curvature ntawm cov yeeb nkab steel yuav tsum yog<0.2 % of the length of the steel pipe, and the ellipse degree ≤ 0.2 % of the outer diameter of the steel pipe. The surface of the entire pipe is <2mm.
2. Ua tib zoo saib xyuas kev thauj mus los ntawm cov kav dej tiv thaiv corrosion:
① Chaw thau khoom thiab tshem tawm: Cov kav dej uas tsis ua rau cov yeeb nkab chaw nres nkoj yuav tsum tsis txhob siv los ua kom cov txheej txheem tiv thaiv corrosion. Tag nrho cov tshuab tsim kho thiab cov khoom siv yuav tsum ua kom tau raws li qhov yuav tsum tau ua thaum lub sijhawm thauj khoom thiab tshem tawm cov txheej txheem. Ua ntej kev thauj khoom, qib pretreatment, cov khoom siv, thiab thickness ntawm lub raj zoo yuav tsum tau kuaj ua ntej, thiab nws yuav tsum tsis txhob sib xyaw.
② Kev thauj mus los: Lub laub lub rooj tsavxwm yuav tsum tau teeb tsa ntawm lub tsheb thauj khoom thiab lub tsheb tavxij. Thaum thauj cov kav dej los tiv thaiv corrosion, nws yog ib qho tsim nyog yuav tsum tau ntim nws ruaj khov thiab ua kev tiv thaiv kev tiv thaiv ntawm cov txheej txheem tiv thaiv corrosion raws sijhawm. Ib daim hlau roj hmab los yog qee cov ntaub ntawv mos yuav tsum tau teeb tsa ntawm cov yeeb nkab anticorrosive thiab cov thav duab los yog kem, thiab cov yeeb nkab anticorrosive yuav tsum tau teeb tsa.
3. Cov qauv kev cia khoom yog dab tsi:
① Cov kav dej, cov kav dej, thiab cov kav dej yuav tsum tau khaws cia kom zoo raws li cov lus qhia. Thaum lub sijhawm khaws cia, ua tib zoo saib xyuas kom tsis txhob xeb, deformation, thiab kev laus.
② Kuj tseem muaj cov khoom siv xws li qee cov iav ntaub, cov hlua khi, thiab lub tes tsho kub-shrinking uas yuav tsum tau muab khaws cia rau hauv qhov chaw qhuav thiab qhov cua.
③ Cov khoom siv xws li cov kav dej, cov kav dej, thiab cov li qub tuaj yeem muab faib ua qhov qhib-air cia. Tau kawg, qhov chaw cia khoom xaiv yuav tsum ua kom lub pob zeb tiaj tus thiab tsis muaj pob zeb, thiab yuav tsum tsis txhob muaj dej nyob hauv av. Txoj kev nqes hav yog lav ntawm 1% mus rau 2%, thiab muaj cov kwj deg.
④ Cov kav dej tiv thaiv kab mob hauv lub tsev yuav tsum tau muab tso rau hauv cov txheej txheem palletizing, thiab qhov siab xav tau los xyuas kom meej tias cov yeeb nkab tsis ruaj khov. Packing cais raws li qhov sib txawv specifications thiab cov ntaub ntawv. Muab lub cushion nruab nrab ntawm txhua txheej ntawm cov kav dej tiv thaiv corrosion, thiab nteg ob kab hauv ncoo ntoo hauv qab lub raj.
⑤ Yog tias nws yog nyob rau ntawm kev tsim kho, qee qhov yuav tsum tau khaws cia ntawm cov kav dej: ob ceg ntawm cov ntaub qhwv yuav tsum tau siv rau hauv qab. Qhov kev ncua deb ntawm qhov nruab nrab yog li 4m mus rau 8m. Lub raj thiab cov yeeb nkab anticorrosive yuav tsum tau padded nrog kev sib cais yooj yim.
