Cov lus qhia siv PPGI / PPGL xim coated steel kauj

1. Kev ceev faj rau kev xaiv cov khoom siv xim coated steel kauj:
Xim coated steel kaujraug xaiv raws li lawv lub hom phiaj siv, kom ntseeg tau tias lawv yog ob qho tib si haum rau kev siv thiab raug nqi. Lub ntsiab kev txiav txim siab yog qhov chaw nyob sab nraud uas cov xim coated steel coil tuaj yeem cuam tshuam nrog, nrog rau cov chaw nyob hauv ib puag ncig, xws li cov chaw nyob deb nroog, thaj chaw hauv nroog, chaw ua lag luam, thiab huab cua hauv hiav txwv. Nyob rau tib lub sijhawm, xav txog qhov tshwj xeeb ntawm cov kua qaub, alkali, ntsev, av noo, teeb pom kev zoo, qhov cua, thiab lwm yam rau kev siv tiag tiag, kev xaiv cov ntaub ntawv tuaj yeem txiav txim siab cais.

2.Kev ceev faj rau kev khaws cia, kev thauj mus los, thiab kev thauj khoom / tshem tawm cov xim coated coil:
1. PPGI / PPGLcov khoom siv xim coated yuav tsum tau muab khaws cia rau hauv qhov chaw qhuav thiab qhov cua, kom deb ntawm cov kuab tshuaj organic xws li acids, alkalis, ntsev, thiab corrosive media;
2. Thaum lub sij hawm kev thauj mus los thiab kev thauj khoom thiab kev thauj mus los, cov xim coated steel coil yuav tsum tau tiv thaiv los ntawm xeb los ntawm nag, daus, pos huab nkag, xim zaj duab xis puas, muaj kuab paug, sib tsoo, squeezing, thiab lwm yam;
3. Cov khoom yob yuav tsum raug thauj mus rau hauv nws lub xeev qub ntawm lub Hoobkas thiab cov khoom ntim khoom qub tsis tuaj yeem muab tshem tawm ntawm qhov xav tau.

3. Kev ceev faj rau kev ua thiab kev teeb tsa ntawm cov xim coated steel kauj:
1. Raws li cov qauv tsim, ua raws li lub hauv paus ntsiab lus ntawm kev xaiv cov khoom lag luam los ntawm tib lub chaw tsim khoom thiab batch rau tib qhov project kom tsis txhob muaj kev cuam tshuam ntawm cov xim sib txawv ntawm qhov zoo nkauj;
2. Yog tias muaj qhov tshwm sim lossis qhov txawv txav tsis zoo tom qab tau txais cov khoom, nws yuav tsum raug txiav tawm thiab yuav tsum hu rau tus neeg muag khoom.
3. Xim coated steel kauj yuav tsum tsis txhob muaj qhov kub thiab txias (yuav tsum siab tshaj 7 degree), xaiv cov khoom siv kho kom haum xim coated steel kauj, thiab xyuas cov ntsuas zoo xws li qhov chaw thiab adhesion ntawm cov khoom thaum ua thiab siv. Yog tias muaj teeb meem zoo, qhov laj thawj yuav tsum raug txheeb xyuas thiab ntsuas yuav tsum tau ua ua ntej txuas ntxiv ua thiab siv;
4. Thaum lub sij hawm ua, kev teeb tsa thiab kev siv cov xim coated steel coil, nws yog ib qho tsim nyog kom tsis txhob txiav cov khoom kub kub hlau hmoov adhesion, zawv zawg thiab kev sib tsoo ntawm cov khaubncaws sab nraud povtseg ntawm cov xim pobzeb profiles, daim ntawv thov ntawm cov cuab yeej siv tshuab, stepping ntawm cov tawv nqaij tawv, thiab lwm yam. kev puas tsuaj rau cov khoom tiv thaiv txheej. Cov bolts kho yog kaw nrog cov ntaub ntawv tsis muaj dej thiab tiv thaiv corrosion; Yog tias qhov kev puas tsuaj tshwm sim thaum lub sijhawm ua haujlwm thiab kev teeb tsa, cov txheej txheem kho tshwj xeeb yuav tsum tau siv raws sijhawm kom ntseeg tau tias lub neej kev pabcuam ntawm cov xim coated steel coil;
5. Tom qab kev teeb tsa cov vuas xim, daim ntawv saum npoo thiab txiav yuav tsum tau ceev kom huv si thiab deb ntawm corrosive media xws li cement, acid, alkali, ntsev, thiab lwm yam;
6. Lub sij hawm ntev ncaj qha tshav ntuj thiab lwm yam ultraviolet lub teeb raug txwv tsis pub thaum lub sij hawm thauj mus los, cia, ua, thiab installation ntawm epoxy backing xim rau xim coated phaj;
7. Raws li daim ntawv xim coated rau vov tsev, nws raug nquahu tias txoj kab nqes nruab nrab yuav tsum tsis pub tsawg tshaj 10 degrees. Tom qab kev teeb tsa ntawm daim ntawv xim coated, qhov saum npoo yuav tsum tau ua kom huv si kom ntseeg tau tias lub neej ua haujlwm ntawm cov xim coated board.
