Cov yas pob tshab yog ntau heev, tab sis feem ntau muaj teeb meem nrog nws cov molding. Tus editor tau sau qee cov ntawv thiab sau cov ntsiab lus rau kev siv. Yog tias muaj qhov yuam kev lossis ntxiv, koj tuaj yeem sib tham thiab sib tham hauv cheeb tsam saib.
Nyiaj streaks: cuam tshuam los ntawm anisotropy ntawm kev ntxhov siab sab hauv thaum lub sij hawm sau thiab condensation txheej txheem, qhov kev ntxhov siab tsim nyob rau hauv txoj kab ntsug ua rau cov resin ntws mus rau pem hauv ntej, thiab qhov ntsuas qhov ntsuas ntawm qhov tsis ntws tawm txawv ntawm qhov tsis ntws. kev taw qhia. , tej zaum yuav ua rau tawg ntawm cov khoom. Ntxiv rau kev them nyiaj rau cov txheej txheem txhaj tshuaj molding thiab pwm (saib lub rooj, nws yog qhov zoo tshaj plaws rau anneal cov khoom. Piv txwv li, cov ntaub ntawv PC tuaj yeem ua kom sov siab tshaj 160 degree C rau 3 mus rau 5 feeb, thiab tom qab ntawd txias txias.
Npuas: Feem ntau yog vim cov dej vapor thiab lwm yam roj hauv cov resin tsis tuaj yeem tawm, (thaum lub sij hawm pwm condensation txheej txheem) los yog vim pwm tsis txaus, qhov condensation nto condenses sai heev los tsim "nqus npuas". Nws txoj kev kov yeej yog qhia nyob rau hauv lub rooj.
Lub ntsej muag tsis zoo: Feem ntau yog vim qhov loj roughness ntawm pwm, ntawm qhov tod tes, lub condensation yog ntxov dhau, yog li cov resin tsis tuaj yeem luam lub xeev ntawm pwm nto, tag nrho cov uas ua rau saum npoo tsim me me unevenness, thiab ua cov khoom poob nws cov luster. Nws txoj kev kov yeej yog qhia nyob rau hauv lub rooj.
Vibration kab: yog hais txog cov tuab corrugations tsim los ntawm sprue ua qhov chaw. Yog vim li cas yog tias cov khoom siv pem hauv ntej kawg tau condensed nyob rau hauv cov kab noj hniav vim yog cov viscosity ntau dhau ntawm cov yaj, thiab cov khoom tom qab tawg los ntawm qhov chaw condensation, ua rau cov kab vibration ntawm qhov chaw. Nws txoj kev kov yeej yog qhia nyob rau hauv lub rooj.
Whitening thiab halo: Feem ntau tshwm sim los ntawm cov hmoov av poob rau hauv cov khoom siv raw hauv huab cua lossis cov khoom siv raw muaj dej ntau dhau. Nws txoj kev kov yeej yog qhia nyob rau hauv lub rooj.
Cov pa luam yeeb dawb thiab xim dub: feem ntau yog vim qhov decomposition lossis deterioration ntawm cov resin nyob rau hauv lub thoob vim lub zos overheating ntawm cov yas nyob rau hauv lub thoob. Nws txoj kev kov yeej yog qhia nyob rau hauv lub rooj. Txhawm rau kom meej meej qhia txog cov kev ntsuas los daws cov teeb meem no, cov lus tau teev tseg rau koj siv.
