Raws li peb txhua tus paub, cov hlau zoo tib yam yooj yim tsim ib hom xoob xeb hauv cov cua vim tias nws muaj ntau yam impurities, uas ua rau aggravates corrosion ntawm substrate. Txhawm rau tiv thaiv xeb thiab txhim kho qhov adhesion ntawm topcoat lossis tshuaj tsuag xim, cov hlau yog txau los yog pleev xim rau ntawm qhov chaw. Ua ntej, nws yog chemically los yog electrochemically kho los tsim ib tug ntom thiab nruam phosphating zaj duab xis ntawm cov hlau nto, uas lays lub hauv paus zoo rau ntxiv painting thiab lwm yam kev kho mob ntawm cov hlau.
Qhov ntsuas kub ib txwm muaj hlau phosphating tus neeg sawv cev yog True Room-Temperature Detergent Iron Phosphate rau Aluminium thiab Ferrous Metals. Mixed hlau, chav tsev kub tshuaj ntxuav thiab hlau phosphate. Non-foaming formulation ntawm 70 mus rau 140F.
Qhov kub ntawm cov hlau phosphating tus neeg sawv cev no yog ib qho kev sib xyaw ntawm buffered phosphates, cov dej txias, thiab cov txheej txheem tsis yog hlau ua ke nrog cov qib siab ntawm cov tshuaj detergents tsawg hauv cov kua dej yooj yim.
pH sib npaug thiaj li yuav tsum tau hloov pH me me los yog tsis muaj.
Tsim los siv rau hauv recirculating tshuaj tsuag phosphatizing tshuab.
Ua ib qho iridescent phosphate txheej ntawm ferrous Cheebtsam uas muab kev txhim kho xim adhesion thiab corrosion kuj rau qhov tiav.
Ua ib qho etch thiab lub teeb txheej ntawm aluminium, zinc, thiab galvanized nto.
Raws li lossis tshaj TTC-490D, Hom II tub rog specification los ntawm kev muab cov hlau phosphate txheej hauv thaj tsam ntawm 35 txog 50 mgs / ft2.
Tsis muaj cov hlau thiab muaj qhov ruaj khov heev ntawm qhov kub thiab txias thiab ntau qib pH, nqe qauv HAS (qhov siab tshaj 120 degree F) lossis chlorate (tsis tshua muaj kev ua haujlwm nqaim pH) accelerators. Qhov no tuaj yeem muaj tseeb tshwj xeeb nyob ib puag ncig thaj chaw sib pauv cua sov uas qhov kub tuaj yeem ncav cuag kub.
Ntxiv kev lag luam zoo heev rau kev ua haujlwm phosphate los ntawm kev txuag nyiaj ntau txhiab daus las txhua xyoo hauv cov nqi hluav taws xob.
Siv cov ntaub ntawv:
Concentration: 2-3% los ntawm ntim
Lub hom phiaj ua haujlwm pH: 4.4 - 4.9
Kub: 70-212 degree F (qhov pom zoo kub yog 80 - 160F)
Cim npe nrov: Tuam Tshoj kub kub hlau phosphating tus neeg saib xyuas, Tuam Tshoj ib txwm kub hlau phosphating tus neeg saib xyuas manufacturers, lwm tus neeg, Hoobkas
