Guangdong Zhonglian Aluminium tau dhau lub teb chaws zoo ntawm Fangyuan ntawv pov thawj, ISO9001 ntawv pov thawj, Tuam Tshoj Fangyuan Committee certification. Aluminium profile zoo ntawm "Yalian Hom" raws li lub teb chaws GB5237-2008, GB / 8013-87 qauv, thoob ntiaj teb JISH8602: 1992 tus qauv. Los ntawm kev tswj cov txheej txheem nruj thiab kev soj ntsuam cov txheej txheem, kom ntseeg tau cov khoom zoo.
Oxidation Ntau Lawm Txheej Txheem Thiab Kev Tswj Xyuas Zoo

2. Los ntawm kev tshawb pom txhais tau tias kom paub meej:
(1) Tshawb xyuas qhov kev sib khi zoo ntawm txhua pawg;
(2) Ntsuas cov tshuaj ntsev ntsev ntawm txhua pawg;
(3) Random check ntawm zaj duab xis thickness thiab profile loj raws li 10 feem pua kom muaj nuj nqis;
(4) Ntsuas cov khoom siv kho tshuab ntawm txhua pawg;
(5) Ua kom cov khoom zoo los ntawm kev tswj cov txheej txheem nruj.
3. Cov txheej txheem oxidation flow chart
Degreasing - alkali etching - neutralization - oxidation (electrolysis) - xim - sealing - (los yog electrophoresis) - sealing - ziab - tawm rhawv - ntim - warehousing
4. Kev ntsuas cov txheej txheem ntau lawm zoo
(1) Tshawb xyuas cov kua tank ob zaug ib hnub;
(2) Raws li kev xeem, kev tsim khoom yog qhov muaj pes tsawg leeg ntawm cov kua tank thiab PH tus nqi ntawm cov kua tank;
(3) Tsis siv neeg tswj lub sijhawm ua haujlwm ntawm cov ntawv hauv txhua qhov;
(4) nruj me ntsis tswj qhov kub ntawm txhua qhov zawj;
(5) Cov kws tshaj lij puv sijhawm yuav tsum saib xyuas cov txheej txheem thiab taug qab thiab kuaj lub cev thiab tshuaj lom neeg ntawm txhua txoj haujlwm.
