Dab tsi yog qhov tsim nyog ntsuas rau tshuab pwm pwm

Qhov ntsuas kub haum rauTshuab Cov Khoom Mouldfeem ntau ntawm 180 ℃ thiab 220 ℃. Nyob rau hauv qhov ntsuas kub no, cov yas muaj peev xwm tag nrho cov yas kom tsim cov npuas, yog li ua kom muaj zog thiab lub zog ntawm cov khoom. ‌

Qhov kub thiab txias yuav tsum muaj rau cov khoom sib txawv thiab cov khoom lag luam

HDPE: qhov ntsuas kub ntawm lubtshuab moulding tshuabFeem ntau tau teeb tsa ntawm 170-210 ℃, thiab cov tshwj xeeb kub uas yuav tsum tau hloov kho raws li qhov loj me ntawm cov khoom. Cov khoom me me muaj qis dua kub, thaum cov khoom loj yuav tsum muaj qhov kub siab dua. Tsawg kub tuaj yeem ua rau embryo rupture, thaum lub sij hawm siab kub yuav ua rau cov phab ntsa tsis sib xws ntawm cov khoom.

Cov Khoom Siv TPV: Qhov pom zoo ziab qhov kub ua ntej tshuab moulding yog 170 ±, thiab cov pwm kub feem ntau pom zoo kom tsawg dua 40 ℃. Txo cov pwm kub pab nrog cov khoom lag luam thiab kev sib tw ceev, tab sis tuaj yeem cuam tshuam rau cov tsos thiab lub zog ntawm cov khoom.

Tus cawv ntawm qhov kub ntawm lub tshuab moulding

Tsis tshua muaj kub: nws tuaj yeem ua rau cov yas kom tsis yaj ua kom tiav, cuam tshuam rau qhov zoo ntawm tshuab moulding, ua rau nyob rau hauv cov tsis xws luag thiab txo qis ncos thiab kev ua tau zoo.

Kev kub siab: nws tuaj yeem ua rau muaj kev sib tw ntau dhau ntawm cov yas, uas tuaj yeem yooj yim tsim npuas hauv cov khoom, cuam tshuam nws cov khoom siv tshuab thiab kav ntev. Tsis tas li ntawd, cov kub tau ua rau cov roj hmab kom zoo nkauj, tsim cov roj teeb meem uas ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv thiab ib puag ncig.

Kev ntsuas tshwj xeeb rau kev tswj qhov kub

Cov Khoom Siv Kom Qhuav: Ua ntej tshuab moulding, xyuas kom cov khoom tau qhuav kom tsis txhob muaj huab cua qhov uas tuaj yeem cuam tshuam rau cov khoom lag luam ntawm qhov kawg pwm.

Cua sov kub ntawm lub billet: cov cua sov ntawm cov billet yuav tsum tau nruj me ntsis tswj tau. Yog tias nws tseem siab dhau, lub viscosity ntawm molten cov khoom yuav tsawg zuj zus thiab nws yooj yim rau deform. Yog tias nws qis dhau lawm, nws yuav nthuav dav ntxiv sab hauv kev ntxhov siab hauv cov khoom, uas yog nquag rau kev ntxhov siab thaum siv.
