40Tyog ib qho -coat deg kho mob uas tshwj xeeb tsim los rau daim ntawv cog lus elastomers, xws li castable polyurethane, millable polyurethane, epoxy resin, phenolic resin thiab ob peb tshwj xeeb roj hmab nrog hlau thiab lwm yam rigid substrates. Hauv daim ntawv thov tshwj xeeb, kuj tuaj yeem tsim nyog rau kev sib txuas ntawm cov thermoplastic urethane thiab rigid substrates.
Nta thiab Cov txiaj ntsig
Ntau yam -haum rau ntau yam hlau thiab tsis yog - hlau substrate. Casting thiab molding txheej txheem.
Kev ziab sai sai - Dries sai kom tso cai rau lub sijhawm hloov pauv sai los ntawm kev siv cov kuab tshuaj tshwj xeeb.
Yooj yim rau Siv - Yuav siv tau los ntawm tshuaj tsuag, dipping, polyester roller thiab txhuam daim ntawv thov.
Environmental Resistance -Ntxiv durability rau hnyav ib puag ncig raug, nrog rau kub kub, ntsev tsuag, hnyav ambient thiab lwm yam ib puag ncig raug.

Tshuaj muaj pes tsawg leeg
Ntau cov polymer resins tau ruaj khov nyob hauv cov kuab tshuaj organic.
Daim ntawv thov
Kev npaj nto- Ua kom huv si ntawm cov hlau ua ntej 40T daim ntawv thov. Tshem cov roj thiab hmoov av los ntawm cov hlau nto, sandblast lub hlau nto kom nws
nto roughness ntau dua 15 microns. Rau txhuas nto, peb pom zoo kom siv alumina ua tus neeg sawv cev los ntxuav cov plua plav seem ntawm cov xuab zeb nto dua.
Cov txheej txheem tshuaj kuj tseem siv tau, xws li phosphating, passivation, electrophoresis, thiab lwm yam.Sib tov- Tsis muaj kev ntxhov siab ua ntej thov, thiab diluted 40T raws li
cov cai thov. Siv tshwj xeeb thinner los ntawm usas diluent. Lub diluent yuav tsum tau ntxiv maj mam nyob rau hauv thaum agitation kom tsis txhob muaj theem sib cais.
Txhuam- Siv tag nrho lub zog, rau qhov loj me lossis cov duab zoo ntawm cov khoom pom zoo me ntsis dilution, dilution ratio ntawm 100/30 txog 80.
Txau- Txhawm rau kom tsis txhob co-web (cov tshuaj tsuag qhuav), nws yuav tsum tau diluted nyob rau hauv daim ntawv thov tshuaj tsuag, pom zoo dilution ratio yog hais txog 100/60 rau 150.
Dip- Dilution ratio ntawm 100/150 rau 300 yog pom zoo rau dipping daim ntawv thov.
Adhesive Zaj duab xis- Zaj duab xis qhuav ntawm 15-30 microns raug pom zoo rau 40T.
Mus txog lub hom phiaj qhuav zaj duab xis thickness yuav pom tseeb gloss.
Qhuav- Cov zaj duab xis ntub dej yuav tsum tau qhuav kom huv si kom huv si ua ntej kho, qhov no yuav siv sij hawm 60 feeb lossis ntau dua ntawm chav tsev kub. Zaj duab xis yuav raug yuam kom qhuav ntawm siab dua
kub rau lub sij hawm luv luv. Cov huab cua siab tshaj plaws ntawm qhov ntsuas kub tsawg kawg nkaus (15-20 mins @ 50-60C qhov cub zoo ventilated) kuj tuaj yeem muab cov txiaj ntsig xav tau.
Ua ntej- Cov khoom uas coated nrog 40T yuav vulcanized tam sim ntawd tom qab huab cua- ziab, thaum prebake tuaj yeem txhim kho lub zog cohesive. Prebake txheej txheem: 1-2 teev @ 110-120℃yog rau qhov qub, qhov loj yuav tsum tau nce lub sijhawm ci rau 2-4 teev.
Kho / Vulcanization- Coated qhov chaw yuav tsum tau ua tiav cov txheej txheem molding raws sij hawm tom qab prebaking, lub sij hawm kho thiab kub yog tib yam li cov txheej txheem txheej txheem yuav tsum tau vulcanize
lub urethane compound yog molded.
