Tam sim no, ntau qhov kev txhaj tshuaj pwm ua cov tuam txhab tsim khoom sivBakelite txhaj tshuajmolding tshuab thiabyas txhaj tshuajmolding tshuab.Muaj qhov sib txawv ntawm Dewei casting bakelite txhaj tshuaj molding tshuab thiab yas txhaj tshuaj molding tshuab.Bakelite yog PF (phenolic cob).Bakelite yog ib qho kev lag luam yas thaum ntxov, uas paub txog kev tsim khoom hauv Tebchaws Meskas hauv xyoo 1910. Cia peb saib seb qhov txawv yog dab tsi?
Cov khoom siv raw rau kev tsim bakelite feem ntau yog phenols thiab aldehydes, thiab phenol thiab formaldehyde feem ntau yog siv.Lawv tau txais los ntawm polycondensation nyob rau hauv catalysis ntawm acid, alkali thiab lwm yam catalysts.Kev tsim khoom lag luam feem ntau suav nrog cov txheej txheem qhuav thiab txheej txheem ntub.
Phenol thiab aldehyde tuaj yeem tsim tau ob hom PF raws li kev ua ntawm cov catalysts sib txawv: ib qho yog thermoplastic PF thiab lwm yam yog thermosetting PF.Cov qub tuaj yeem kho tau rau hauv lub cev qauv nkaus xwb los ntawm kev ntxiv tus neeg saib xyuas thiab cua sov, thaum lub sijhawm tom kawg tuaj yeem ua lub cev qauv ntev npaum li qhov cua sov yam tsis muaj tus neeg sawv cev kho.
Txawm hais tias thermoplastic pf lossis thermosetting PF, tsuas yog kev sib pauv network tsim los ntawm kev kho tuaj yeem siv tau.Cov txheej txheem kho yog qhov txuas ntxiv ntawm cov tshuaj tiv thaiv polycondensation thiab tsim cov khoom loj kawg.Cov txheej txheem no txawv ntawm qhov melting thiab curing ntawm cov thermoplastic.Nws yog irreversible, nrog rau ob qho tib si lub cev thiab tshuaj txheej txheem.
PF tuaj yeem txhaj tshuaj molded los ntawm txoj kev zoo ib yam li cov thermoplastic.Pf siv rau kev txhaj tshuaj molding yuav tsum zoo fluidity, molding nyob rau hauv qis txhaj tshuaj, siab thermal rigidity thiab ceev ceev hardening ceev, zoo gloss ntawm cov yas qhov chaw, yooj yim demoulding thiab tsis muaj kuab paug rau pwm.Txawm li cas los xij, kev txhaj tshuaj molding kuj muaj nws qhov tsis zoo.Piv txwv li, cov yaj yog txwv los ntawm hom muab tub lim, nws tsis haum rau molding yas qhov chaw nrog ntau cov ntxig, thiab ntau lub rooj vag thiab ntws raws tom qab kho tsis tuaj yeem rov ua dua thiab tsuas yog muab pov tseg.
Hauv luv luv, thermoplastic PF tuaj yeem tsim los ntawm lub tshuab txhaj tshuaj zoo tib yam, tab sis cov txheej txheem yuav tsum nruj me ntsis tswj.Thermosetting pf yuav tsum tau tsim los ntawm PF tshwj xeeb txhaj tshuaj molding tshuab (chim thiab ntsia hlau txawv ntawm cov tshuab txhaj tshuaj molding tshuab), thiab pwm kuj yuav tsum siv cov qauv tsim tshwj xeeb!
Sino Vision Tsheb & Service Co., txwv, nyob rau hauv Huangyan Town, Taizhou, tsom rau kev txhaj tshuaj molding ua xws li bakelite, BMC txhaj molding thiab precision yas txhaj molding.Bakelite thiab BMC txhaj tshuaj molding khoom yog dav siv nyob rau hauv txhua yam khoom siv hauv chav ua noj, electromechanical thiab khoom siv hauv tsev.Lub tuam txhab muaj ib tug muaj zog engineering thiab technical team, uas tau cog lus los tsim cov khoom zoo thiab zoo nkauj tus nqi rau cov neeg muas zaub, uas muaj peev xwm ua tau raws li ntau yam kev xav tau ntawm cov neeg muas zaub.
