Cationic Epoxy Electrocoat

Peb yog Quzhou Chengji Txheej los ntawm Zhejiang, Suav. Rau cov khoom no, peb muab ob txoj kev paub tab. Peb sivepoxy cobthiab covtxheej txheem cationic. Qhov no yog txoj hauv kev zoo tshaj plaws thiab ua pov thawj rau cathodic electrocoat. Epoxy muab cov ntoo khaub lig ntom ntom - txuas cov qauv thiab cov tshuaj lom neeg zoo. Cov txheej txheem cationic muab txawm tias deposition thiab muaj zog daim ntawv cog lus rau cov hlau. Ua ke, lawv tsim ib qho kev tiv thaiv xeb uas nyuaj rau tuav. Rau hnyav-lub luag haujlwm siv zoo litsheb lub cev, chassis qhov chaw, thiab cov khoom siv, qhov no yog tus qauv uas lwm tus ua raws.

Lub hauv paus ntawm cov khoom no yog kev hloov kho amine ntawm epoxy resin. Peb ntxiv amine pawg rau cov saw hlau epoxy. Cov pab pawg amine no tau hloov mus ua dej -soluble ntsev nrog cov organic acid. Qhov no muab cov resin particles lawv tus nqi zoo. Lub hardener yog blocked aromatic isocyanate. Nws qhib thaum kub kub thiab reacts nrog cov resin los tsim ib lub network nruj. Thaum lub sijhawm tsim khoom, peb sivGPCtswj cov resin qhov hnyav molecular. Peb khaws nws zoo ib yam. Koj tsis tas yuav nco ntsoov cov ntsiab lus no. Tsuas paub tiaspeb siv cov cuab yeej siv siab - thev naus laus zis kom paub tseeb tias txhua pawg ntawm cov resin zoo ib yam. Qhov no muab koj cov xim ruaj khov, txhim khu kev qha.

Kev tiv thaiv xeb ntawm qhov system no yog qhov zoo tshaj plaws hauv kev lag luam. Nrog ib tug zoo phosphate txheej thiab a25 micronzaj duab xis, nws yooj yim dhau1000 teevhauvASTM B117ntsev tsuag test. Nyob rau hauv lub tougher cycle test, lub creep los ntawm kos yog nyob rau hauv2 hlitom qab 10 lub lis piam. Ib tug neeg ua chassis qhov chaw rau cov khoom siv mining. Cov khoom siv yog siv rau hauv cov xwm txheej hnyav. Lawv xav tau1500 teevntawm ntsev tsuag. Peb cov khoom dhau los. Tam sim no lawv muab rau lub lag luam mining loj. Cov txheej kuj tiv cov tshuaj muaj zog. Nws tuaj yeem ua tau10% hydrochloric acid, 10% sulfuric acid, thiab 10% sodium hydroxiderau tshaj48 hnu. Qhov no yog qhov zoo tshaj plaws hauv kev tiv thaiv xeb.

Thaum muab kev tiv thaiv xeb zoo tshaj plaws, nws kuj muaj lub zog zoo heev. Cov cwj mem hardness yog3 H rau 4 H. Nws tiv taus khawb thiab hnav. Tab sis nws kuj hloov tau. Nws hla tus50 kg cmcuam ​​tshuam kuaj. Nws muaj ib tug yooj ntawm1 hli. Hauv T-kev sim khoov, nws tuaj yeem dhau ntawm0 rau 1t. Qhov no txhais tau tias koj tuaj yeem khoov lub steel tiaj tus, thiab cov txheej yuav tsis tawg. Ib tus neeg siv khoom stamped qhov chaw. Lawv ua qhov tob tob. Lawv cov txheej qub ib txwm tawg. Nrog peb cov khoom, lawv cov khoom zoo tau mus los ntawm 70% mus rau ntau dua 95%. Qhov no yog tus nqi ntawm txheej txheej uas nyuaj tab sis tsis nkig. Nws yogzoo meej rau qhov chaw uas xav tau kev ua haujlwm sib sib zog nqus.

Cov tshuab no tau siv rau ze li 50 xyoo. Nws yog tus qauv kub rau tsheb lub cev xeb tiv thaiv. Peb cov khoom ua tau raws li cov qauv ntawm lub ntiaj teb cov neeg tsim tsheb sab saum toj. Nws ntsibGMAW 14867, VW 1210 TSI, thiabFord's WSS-M2P190-D. Nws yog siv nyob rau hauv cov khoom chains ntawm BMW, Mercedes, VW, thiab GM. Ib tug neeg muab khoom rau VW. Ntawm qhov chaw muag khoom, tus kws tshuaj xyuas pom tias peb cov khoom muaj VW PV 1210 daim ntawv qhia. Lawv dhau qhov kev tshuaj xyuas cov khoom ntawm qhov chaw. Qhov no yog lub zog ntawm cov khoom uas tau uakuaj los ntawm cov neeg xav tau tshaj plaws hauv ntiaj teb. Nws yog qhov txiaj ntsig tseem ceeb uas lwm cov thev naus laus zis tsis tuaj yeem sib xws.
