Tsis tshua muaj siab txhaj tshuaj molding

Kev txhaj tshuaj qis-moulding yog ib hom zoo kawg cov txheej txheem uas siv kev txhaj tshuaj tsis tshua muaj siab ({} mpa mult khoom rau hauv pwm thiab kho nws sai. Daim tawv nqaij tau muab tso rau hauv cov pwm ua ntej, thiab tom qab ntawd Molten cov yas tau txhaj rau kab noj hniav los ntawm kev kaw cov ntsia hlau, thiab tom qab ntawd cov khoom yog tau tom qab kho thiab puab. Cov khoom siv rau cov tawv nqaij qis tuaj yeem yog cov ntaub qhwv lossis pvc npuag.

Cov khoom siv lub cev thiab tshuaj lom neeg ntawm cov khoom siv kub yaj yog siv los ua kom distulation, cov hmoov av tsis kam thiab lwm yam kev cuam tshuam, uas ua lub luag haujlwm zoo hauv kev tiv thaiv hluav taws xob Cheebtsam.

Ntawm tam sim no, tus txheej txheem no tau siv dav hauv kev tsim cov tsheb tiv thaiv tsheb, KOOM Cov zov thiab cov tub ceev xwm parcel.

(1) Kev txhaj tshuaj tiv thaiv qis dua molding yog kom fuse cov khoom siv tawv nqaij nrog cov ntaub ntawv yas, yog li tsis muaj qhov ua tau ntawm tatting tawm.

(2) Cov txheej txheem ntawm kev txhaj tshuaj tsis tshua muaj hluav taws xob muaj ntau txoj kev phooj ywg vim tias tsis muaj cov txheej txheem lo kua nplaum uas tsim nyog rau cov txheej txheem molding.

(3) Tus qauv sab hauv ntawm cov siab siv hluav taws xob ob chav ua qauv moulded, thiab kev ywj pheej ntawm cov txheej txheem qub, thiab cov qauv ua qauv yog qhov pom tseeb thiab nruj dua.

(4) Kev txhaj tshuaj tiv thaiv qis tsis xav tau cov cladding ntxiv, uas txhim kho kev ua tau zoo.

(5) Kev txhaj tshuaj hluav taws xob qis cov khoom muaj cov tes ua tau zoo thiab cov tsos.

(6) Cov khoom lag luam qis dua molding cov khoom muaj cov tshuaj tiv thaiv qis, uas tuaj yeem tiv thaiv cov khoom sab hauv ntawm cov khoom lag luam thiab tus lej seem.

1) Npuag Ductility thiab Kev Ntshaum

Tam sim no, cov ntaub siv hauv kev txhaj tshuaj tsawg Vim tias lub compression ntawm cov pwm thiab qhov extrusion ntawm molten yas, lub sijhawm ntev thiab tom qab txuas ntxiv ntawm cov khoom kuj sib txawv. Ib qho teeb meem tseem ceeb tshaj plaws yog: SUPPAGE ntawm cov khoom siv, tawg, tawg paj. Ntawd yog, nyob rau hauv cov ntaub ntawv ntawm tas li kev tuag lub xeev thiab cov txheej txheem tas li, cov yam ntxwv ntawm cov ntaub muaj kev cuam tshuam zoo rau qhov zoo ntawm cov khoom. Tib Elongation ntev ntev thiab hloov pauv cov pwm sib txawv kuj muaj qhov sib txawv ntawm cov qauv siv tau vim muaj cov qauv kev txwv, thiab qee cov pwm yuav muaj cov kev xav tau siab rau transverse elongation. Yog li nyob rau hauv qhov kev sim ntau lawm ntawm cov khoom tshiab, pwm pwm yuav tsum xav txog qhov teeb meem no.

2) flowability cov yas

Qhov ntsuas kom ntsuas cov felliticly ntawm yas yog: Melt Index Mi tus nqi. Peb txhua tus paub tias kev ntws ntawm cov yas ntawm cov ntaub yog ntau dua li ntawm cov pwm du dua ntawm cov ntaub puab du Tus nqi qeeb qeeb yuav zam lwm cov teeb meem zoo li cov teeb meem ntawm cov khoom lag luam, xws li cov khoom sib khi, cov khoom ploj, thiab lwm yam.
