Qhov kub hloov thaum lub sij hawm molding txheej txheem ntawm FRP yog ntau nyuaj.Vim tias cov yas yog cov khoom siv hluav taws xob tsis zoo, qhov kub ntawm qhov sib txawv ntawm qhov nruab nrab thiab cov ntug ntawm cov khoom yog qhov loj thaum pib molding, uas yuav ua rau kev kho thiab kev sib txuas ntawm cov tshuaj tiv thaiv tsis tau pib tib lub sijhawm nyob rau hauv lub puab thiab txheej txheej ntawm cov khoom.
Nyob rau ntawm qhov chaw tsis ua rau lub zog thiab lwm yam kev ua tau zoo ntawm cov khoom, qhov tsim nyog nce qhov kub ntawm molding yog qhov zoo los ua kom luv lub voj voog molding thiab txhim kho cov khoom zoo.
Yog hais tias lub molding kub tsawg dhau lawm, tsis yog tsuas yog cov khoom melted muaj viscosity siab thiab tsis zoo fluidity, tab sis kuj vim hais tias cov crosslinking cov tshuaj tiv thaiv yog ib qho nyuaj rau mus tas li, cov khoom muaj zog tsis siab, qhov tsos yog dull, thiab pwm sticking thiab ejection deformation. tshwm sim thaum demolding.
Lub molding kub yog pwm kub teev thaum lub sij hawm molding.Cov txheej txheem no txiav txim siab qhov hloov pauv cua sov ntawm cov pwm mus rau cov khoom siv hauv cov kab noj hniav, thiab muaj kev txiav txim siab ntawm cov melting, ntws thiab solidification ntawm cov khoom.
Cov txheej txheej txheej txheej txheej yog kho ua ntej los ntawm tshav kub los tsim ib lub plhaub tawv txheej, thaum tom qab curing shrinkage ntawm cov khoom txheej sab hauv yog txwv los ntawm cov txheej txheej tawv tawv, uas ua rau muaj kev ntxhov siab nyob rau hauv cov txheej txheem ntawm cov khoom molded, thiab cov txheej sab hauv yog muaj qhov seem tensile kev nyuaj siab, lub hav zoov ntawm residual kev nyuaj siab yuav ua rau cov khoom warp, tawg thiab txo lub zog.
Yog li ntawd, kev ntsuas los txo qhov kub ntawm qhov sib txawv ntawm sab hauv thiab sab nraud ntawm cov khoom siv hauv pwm kab noj hniav thiab tshem tawm qhov kev kho tsis sib xws yog ib qho tseem ceeb rau kev tau txais cov khoom zoo.
SMC molding kub nyob ntawm qhov kub thiab txias ntawm qhov kub thiab txias ntawm qhov txheej txheem kho.Feem ntau qhov kub ntawm qhov kub thiab txias me ntsis yog qhov kub ntawm qhov kub thiab txias, uas feem ntau yog 135 ~ 170 ℃ thiab txiav txim siab los ntawm kev sim;qhov curing tus nqi yog ceev Qhov kub ntawm qhov system yog qis dua, thiab qhov kub ntawm qhov system nrog qeeb curing tus nqi siab dua.
Thaum tsim cov khoom siv phab ntsa nyias nyias, siv qhov kev txwv sab saud ntawm qhov kub thiab txias, thiab tsim cov khoom tuab-walled tuaj yeem ua rau qis qis ntawm qhov kub thiab txias.Txawm li cas los xij, thaum tsim cov khoom nyias nyias nrog qhov tob loj, qhov qis qis ntawm qhov kub thiab txias yuav tsum tau coj mus rau qhov ntev ntawm cov txheej txheem los tiv thaiv cov khoom solidification thaum lub sij hawm ntws.
