Qhov kub hloov pauv thaum lub sijhawm molding ntawm FRP nyuaj dua. Vim tias yas yog tus neeg coj cua sov tsis zoo, qhov sib txawv ntawm qhov kub thiab txias ntawm qhov chaw thiab ntug ntawm cov khoom siv yog loj thaum pib molding, uas yuav ua rau kev kho thiab kev sib txuas lus tsis pib tib lub sijhawm hauv cov txheej sab hauv thiab sab nraud ntawm cov khoom siv.
Ntawm lub hauv paus ntawm kev tsis ua rau lub zog thiab lwm yam kev ua tau zoo ntawm cov khoom puas tsuaj, kev nce qhov kub ntawm cov pwm kom raug yog qhov zoo rau kev luv lub voj voog molding thiab txhim kho qhov zoo ntawm cov khoom.
Yog tias qhov kub ntawm cov pwm qis dhau, tsis yog tsuas yog cov khoom yaj muaj viscosity siab thiab tsis muaj fluidity xwb, tab sis kuj vim tias qhov kev sib txuas ntawm cov khoom sib txuas nyuaj rau kev ua tiav tag nrho, lub zog ntawm cov khoom tsis siab, qhov tsos tsis zoo, thiab pwm lo thiab ejection deformation tshwm sim thaum lub sijhawm demolding.
Qhov kub ntawm pwm yog qhov kub ntawm pwm uas tau teev tseg thaum lub sijhawm pwm. Cov txheej txheem no txiav txim siab qhov xwm txheej hloov pauv cua sov ntawm pwm mus rau cov khoom hauv qhov, thiab muaj kev cuam tshuam loj rau kev yaj, ntws thiab khov ntawm cov khoom.
Cov khoom siv txheej saum npoo av raug kho ua ntej los ntawm cua sov los tsim cov txheej tawv tawv, thaum qhov kev kho tom qab ntawm cov khoom siv txheej sab hauv raug txwv los ntawm cov txheej tawv tawv sab nraud, ua rau muaj kev ntxhov siab ntawm cov khoom seem hauv cov txheej saum npoo av ntawm cov khoom pwm, thiab cov txheej sab hauv muaj kev ntxhov siab tensile seem, qhov muaj kev ntxhov siab seem yuav ua rau cov khoom tawg, tawg thiab txo qhov muaj zog.
Yog li ntawd, kev ntsuas los txo qhov sib txawv ntawm qhov kub thiab txias ntawm sab hauv thiab sab nraud ntawm cov khoom hauv qhov pwm thiab tshem tawm qhov kho tsis sib xws yog ib qho ntawm cov xwm txheej tseem ceeb rau kev tau txais cov khoom zoo.
Qhov kub ntawm SMC molding nyob ntawm qhov kub siab tshaj plaws thiab qhov ceev ntawm kev kho ntawm lub kaw lus kho. Feem ntau qhov kub thiab txias uas qhov kub siab tshaj plaws qis dua me ntsis yog qhov kub kho, uas feem ntau yog li 135 ~ 170 ℃ thiab txiav txim siab los ntawm kev sim; qhov ceev kho yog ceev Qhov kub ntawm lub kaw lus qis dua, thiab qhov kub ntawm lub kaw lus nrog qhov ceev kho qeeb yog siab dua.
Thaum tsim cov khoom uas muaj phab ntsa nyias, siv qhov txwv siab tshaj plaws ntawm qhov kub thiab txias, thiab kev tsim cov khoom uas muaj phab ntsa tuab tuaj yeem siv qhov txwv qis tshaj plaws ntawm qhov kub thiab txias. Txawm li cas los xij, thaum tsim cov khoom uas muaj phab ntsa nyias nrog qhov tob loj, yuav tsum siv qhov txwv qis tshaj plaws ntawm qhov kub thiab txias vim yog cov txheej txheem ntev kom tiv thaiv cov khoom khov thaum lub sijhawm ntws.
