Qeb: Powder Coat Guide
Koj puas muaj cov lus nug txog cov khoom siv hmoov txheej, daim ntawv thov hmoov, cov khoom siv hmoov?Koj puas muaj kev tsis ntseeg txog koj cov hmoov txheej txheej, ntawm no ib daim ntawv qhia ua tiav hmoov txheej yuav pab koj nrhiav tau cov lus teb txaus los yog kev daws teeb meem.
Cov teeb meem nrog hmoov txheej daim ntawv thov tshaj galvanized nto
Polyester hmoov txheej tshaj kub dip galvanized steel muab qib siab architectural ua kom tiav rau cov khoom hlau nrog cov yam ntxwv zoo ntawm huab cua huab cua.Cov khoom siv hmoov coated ua kom lub zog siab tshaj plaws rau cov khoom siv hlau, uas yuav ua rau cov noobrally muab 50 xyoo + xeb dawb lub neej spans nyob rau hauv feem ntau architectural daim ntawv thov. Txawm li ntawd los tseem muaj qee qhov teeb meem thaum lub sijhawm thov no. Kub dip galvanized nto tau lees paub tias nyuaj rau hmoov txheej txij li lub tshuab tau tsim thawj zaug hauv xyoo 1960. Muaj Galvanizers pib tshawb fawb hauvNyeem ntxiv…
Yuav tiv thaiv hmoov av tawg li cas
Kev tawg tuaj yeem tiv thaiv tau yog tias ob qho tib si lossis ob qho tib si ntawm cov xwm txheej Explosive Limit thiab qhov chaw ntawm qhov hluav taws xob raug zam. Hmoov txheej txheej txheej txheem yuav tsum tau tsim los tiv thaiv ob qho xwm txheej tshwm sim, tab sis vim yog qhov nyuaj ntawm kev tshem tawm tag nrho cov khoom siv hluav taws xob, kev cia siab ntau dua yuav tsum tau muab tso rau ntawm kev tiv thaiv cov hmoov tawg ntau. Qhov no tuaj yeem ua tiav los ntawm kev ua kom ntseeg tau tias cov hmoov hauv huab cua yog khaws cia qis dua 50% ntawm Lower Explosive Limit (LEL). Txiav txim siab LELs ntawm qhov ntauNyeem ntxiv…
Qhov ua rau muaj plua plav tawg thiab hluav taws kub nyhiab thaum tsim cov hmoov txheej
Cov hmoov coatings yog cov khoom siv organic zoo, lawv tuaj yeem ua rau muaj plua plav tawg. Cov plua plav tawg tuaj yeem tawg thaum cov xwm txheej hauv qab no tshwm sim tib lub sijhawm. Muaj cov khoom siv hluav taws xob tam sim no, suav nrog: (a) qhov chaw kub lossis hluav taws kub; (b) hluav taws xob tawm lossis hluav taws xob; (c) hluav taws xob hluav taws xob. Qhov concentration ntawm plua plav hauv huab cua yog nyob nruab nrab ntawm Lower Explosive Limit (LEL) thiab Upper Explosion Limit (UEL). thaum ib txheej ntawm deposited hmoov txheej los yog ib tug huab los rau hauv kev sib cuag nrog ib tugNyeem ntxiv…

Phosphating conversion txheej
Kev lees paub ua ntej kev kho mob rau steel substrates ua ntej siv cov hmoov txheej yog phosphating uas tuaj yeem sib txawv hauv qhov hnyav. Qhov ntau dua qhov hloov dua siab tshiab txheej hnyav qhov ntau dua qhov kev tiv thaiv corrosion ua tiav; qhov qis txheej txheej hnyav qhov zoo dua cov khoom siv kho tshuab. Yog li ntawd, nws yog ib qho tsim nyog los xaiv ib qho kev sib haum xeeb ntawm cov khoom siv kho tshuab thiab kev tiv thaiv corrosion. High phosphate txheej hnyav tuaj yeem ua rau muaj teeb meem nrog cov hmoov txheej hauv cov khoom siv lead ua tawg tuaj yeem tshwm sim thaum txheej txheej raug.Nyeem ntxiv…
