Foundry Txheej Binderyuav tsum tsis txhob randomly tov nrog non{0}}foundry coatings. Txawm hais tias ntawm cov txheej txheem kev lag luam, cov pawg sib txawv thiab cov tshuab yuav tsum tsis txhob sib xyaw ua ke. Tsuas yog matched tshwj xeeb foundry coatings los ntawm tib lub chaw tsim tshuaj paus yog tsim rau nws. Kev sib xyaw tsis raug yuav ua rau muaj ntau yam txheej txheem tsis xws luag thiab cov teeb meem zoo ntawm castings. Customized rau kev ua hauj lwm hauv kev ua haujlwm, Foundry Txheej Binder pab txhim kho adhesion ntawm refractory coatings thiab pwm los yog cores, adapting rau hnyav ua hauj lwm tej yam kev mob nrog rau siab - kub pouring, thermal rwb thaiv tsev thiab xuab zeb adhesion tiv thaiv. Nws cov qauv txheej txheem yog hom phiaj heev.
Hais txog cov khoom siv mis, Foundry Coating Binder poob rau hauv ntau lub tshuab xws li dej -raws li acrylic, dej iav thiab phenolic resin. Txhua qhov system nta qhov tseeb hloov pH qhov tseem ceeb, kho mechanisms thiab compatibilizers. Cov txheej txheem ntawm phab ntsa, hlau tiv thaiv-corrosion coatings, wood coatings thiab lwm yam khoom siv sib txawv resin substrates, pH qhov tseem ceeb, curing additives thiab zaj duab xis- tsim mechanisms. Kev sib xyaw nrog Foundry Txheej Binder ua rau muaj tshuaj lom neeg ntawm cov khoom sib txawv, tam sim ntawd ua rau flocculation, agglomeration, caking thiab gelation, uas ua rau tag nrho cov txheej txheem siv tsis tau.
Txawm tias tsis muaj caking tam sim ntawd, kev ruaj ntseg ntawm cov txheej txheem sib xyaw yuav raug cuam tshuam tag nrho. Tom qab txhuam rau ntawm qhov chaw pwm, qhov teeb meem xws li kev tsim cov yeeb yaj kiab tsis sib xws, cov kab noj hniav shrinkage, pinholes thiab sagging yuav tshwm sim. Thaum lub sij hawm siab - kub molten hlau pouring, cov txheej txheem sib xyaw ua rau muaj kev kub ntxhov thiab kev sib txuas ntawm lub zog. Txheej txheej tev thiab tawg nquag tshwm sim, ua rau muaj qhov tsis xws luag xws li xuab zeb adhesion, burrs, ntxhib qhov chaw thiab qhov hws, zoo heev tsa tus nqi tsis lees paub. Ntxiv mus, mismatched ziab thiab curing ceev ntawm cov txheej txheej sib txawv ua rau cov txheej txheem tsis sib xws ntawm cov dej noo thiab cov seem sab hauv kev ntxhov siab, ntxiv rau cov txheej txheem kev ruaj ntseg.
Hauv kev tsim tawm, tsuas yog qhov kev sib xyaw ua ke uas muaj feem cuam tshuam nrog Foundry Txheej Binder thiab sib phim cov txheej txheej ntawm tib lub koob los ntawm ib lub chaw tsim khoom. Cov khoom lag luam hauv cov txheej txheem no muaj cov qauv tsis sib xws, thiab kev sib xyaw ua ke tuaj yeem txhim kho cov txheej txheem kev ua tau zoo. Tsis tas li ntawd, kev sib xyaw cov txheej txheem los ntawm cov npe sib txawv lossis cov npe sib txawv yog txwv tsis pub, cia nyob ib leeg ua cov txheej txheem kev lag luam lossis kev lag luam. Yog tias cov ntaub ntawv pabcuam yuav tsum tau muab sib xyaw ua ke thaum lub sijhawm tsim khoom, ua kom muaj kev sib raug zoo ntawm cov khoom me me ua ntej. Saib seb puas muaj delamination, caking lossis discoloration tshwm sim. Paub meej tias qhov system ruaj khov ua ntej sib xyaw ua ke kom tsis txhob muaj kev pheej hmoo ntau lawm.
