Kev txhaj tshuaj molding yog ib hom kev txhaj tshuaj molding. Qhov zoo ntawm txoj kev txhaj tshuaj molding yog ceev ceev, kev ua haujlwm siab, kev ua haujlwm tsis siv neeg, ntau yam xim, cov duab yooj yim mus rau complex, loj loj mus rau me me, cov khoom lag luam raug, hloov kho yooj yim, thiab tuaj yeem tsim cov duab zoo. Kev txhaj tshuaj molding yog tsim rau kev tsim khoom loj thiab cov khoom lag luam nyuaj.
Ntawm qhov kub thiab txias, cov khoom siv yas uas yog yaj tag yog nplawm los ntawm cov ntsia hlau thiab txhaj rau hauv pwm kab noj hniav nrog kev kub siab. Tom qab txias thiab kho, cov khoom molding tau txais. Cov txheej txheem no yog tsim rau cov khoom loj ntawm cov khoom sib xws, thiab yog ib qho ntawm cov txheej txheem tseem ceeb.
Niaj hnub no, Qingdao sainuo pe ciab chaw tsim tshuaj paus coj koj kom paub txog peb qhov kub thiab txias ntawm kev txhaj tshuaj molding.

1. chim kub
Txhua yam khoom muaj nws tus kheej melting kub ntau yam. Yog tias qhov kub thiab txias qis, cov khoom yuav tsis yaj zoo. Yog tias qhov kub thiab txias, nws yuav decompose, yog li peb yuav tsum xaiv qhov kub thiab txias. Txawm li cas los xij, muaj qee qhov sib txawv ntawm kev tswj qhov kub thiab txias ntawm lub tshuab txhaj tshuaj molding, yog li peb yuav tsum tau kawm saib lub taub hau roj hmab los tshuaj xyuas seb qhov ntsuas kub puas tsim nyog.
Muaj lub suab txawv txav hauv gluing, pom tseeb tsis tiav melting granular hais rau ntawm cov khoom, thiab cov fluidity tsis zoo heev, uas qhia tau hais tias qhov kub thiab txias yog tsawg heev thiab yuav tsum tau nce.
Lub gluing yog du heev, cov khoom zoo li dej, thiab cov fluidity zoo heev, uas qhia tau hais tias qhov kub thiab txias yuav tsum tau txo.
Cov khoom kub yog qhov tseem ceeb heev. Yog tias nws siab dhau thiab me ntsis decomposed, nws yuav cuam tshuam rau lub zog thiab qhov zoo ntawm cov khoom. Yog li ntawd, qhov kev hloov ntawm cov khoom siv kub yog feem ntau tsis xav txog hauv kev tsim khoom.
2. Pwm kub
Pwm kub ncaj qha cuam tshuam qhov loj ntawm cov khoom. Feem ntau, nws yog qhov zoo dua los teem nws raws li cov khoom siv hauv cov pwm kuaj theem, thiab kho nws me ntsis raws li cov khoom lag luam zoo, yam tsis xav txog qhov kev hloov pauv hauv huab hwm coj ntau lawm.
Thaum cov pwm kub siab, cov yaj fluidity yog qhov zoo, uas yog qhov tsim nyog rau kev tsim, tab sis cov khoom shrinkage nce, thiab qhov loj yuav me dua.
Thaum cov pwm kub tsis tshua muaj, cov yaj fluidity tsis zoo, uas tsis zoo rau kev sib sau, tab sis cov khoom shrinkage txo qis thiab qhov loj me me.
Pwm kub tsis tsuas yog cuam tshuam qhov loj ntawm cov khoom, tab sis kuj txiav txim siab crystallinity. Thaum pwm kub yog siab, lub crystallinity yog loj, thiab thaum pwm kub yog tsawg, lub crystallinity yog me me.
Pwm kub kuj muaj qee yam cuam tshuam rau lub zog ntawm cov khoom. Thaum cov pwm kub tsis tshua muaj, qhov fluidity ntawm cov khoom ua tsis zoo, tom qab ntawd qhov kev sib txuas ntawm cov kab sib txuas yuav raug cuam tshuam, thiab lub zog ntawm cov khoom sib txuas yuav raug txo kom tsawg. Ntxiv mus, thaum pwm kub yog tsawg, lub crystallinity yog tsawg, thiab lub zog yog correspondingly tsawg.
3. ziab kub
Qee cov ntaub ntawv uas muaj cov kab dej lwg me me yuav ua rau kom cov khoom puas ntawm cov polymers, xws li PC, PBT, thiab lwm yam, yog li lawv yuav tsum tau qhuav tag ua ntej molding.
Yog hais tias ib tug tej yam dryness tsis nyob rau hauv qhov chaw, nws yuav tsis tsuas yog accelerate lub decomposition ntawm cov khoom, tab sis kuj tsim ib tug loj tus naj npawb ntawm npuas. Lub fluidity kuj yuav ua tau zoo heev, thiab nws yog ib qho yooj yim los tsim cov teebmeem phem xws li drape pem hauv ntej. Yog li nws yuav tsum tau qhuav ua ntej molding.
Qingdao Sainuo Tshuaj Co., Ltd. Peb yog cov chaw tsim khoom rau PE ciab, PP ciab, OPE ciab, EVA ciab, PEMA, EBS, Zinc / Calcium Stearate …. Peb cov khoom tau dhau los ntawm REACH, ROHS, PAHS, FDA kuaj.
Sainuo so assured ciab, zoo siab txais tos koj nug!
