Plaub txoj kev los pab txo cov ntsia hlau hnav ntawm kev txhaj tshuaj molding tshuab

Ua rau cov ntsia hlau hnav thiab cov hau kev los txo hnav:
Txhua hom yas muaj qhov zoo tagnrho plasticizing ua qhov kub thiab txias. Lub chim ua qhov kub thiab txias yuav tsum tau tswj kom nws nyob ze rau qhov ntsuas kub no. Thaum cov yas granular nkag mus rau hauv lub thoob los ntawm lub hopper, nws yuav xub mus txog qhov chaw pub mis, thiab kev sib txhuam qhuav yuav inevitably tshwm sim nyob rau hauv seem pub. Thaum cov plastics tsis tau rhuab txaus thiab melting yog tsis sib xws, nws yog ib qho yooj yim mus ua kom muaj zog hnav ntawm lub puab phab ntsa ntawm lub chim thiab nto ntawm cov ntsia hlau. Ib yam li ntawd, nyob rau hauv seem compression thiab homogenization seem, yog hais tias lub melting lub xeev ntawm plastics yog disordered thiab tsis sib xws, nws kuj yuav ua rau muaj zog hnav.
Qhov ceev yuav tsum tau kho kom raug. Vim tias qee cov yas tau ntxiv nrog cov tshuaj ntxiv dag zog, xws li iav fiber ntau, cov zaub mov lossis lwm cov khoom ntim. Kev sib txhuam ntawm cov tshuaj no ntawm cov ntaub ntawv hlau feem ntau ntau dua li cov yas molten. Thaum txhaj tshuaj molding cov yas no, yog tias koj siv qhov kev sib hloov ceev, nws yuav ua rau lub zog shear ntawm cov yas, thiab tib lub sij hawm, nws tseem yuav ua rau qhov kev txhawb zog sib raug zoo tsim cov fiber ntau torn. Cov torn fibers muaj qhov xaus, uas ua rau kom muaj zog hnav. Thaum cov zaub mov inorganic swb ntawm cov hlau nto ntawm kev kub ceev, lawv cov nyhuv scraping tsis yog me me. Yog li ntawd, qhov ceev yuav tsum tsis txhob hloov siab heev.
Lub sundries nyob rau hauv cov yas yuav tsum tau muab tshem tawm. Feem ntau hais lus, cov yas tshiab yuav hauv cov ntim thawj zaug tsis muaj khoom noj, tab sis nws yuav raug muab sib xyaw nrog cov khoom siv tom qab kev thauj mus los, hnyav, ziab, xim sib xyaw, tshwj xeeb tshaj yog ntxiv cov khoom siv rov ua dua tshiab. Me me li hlau filings, loj li cua sov nplhaib ceev, ntawv clips, thiab txawm ib tug series ntawm warehouse keys tau muab tov rau hauv lub thoob, uas yog nws tus kheej-pom zoo (lub thoob yuav puas tib lub sij hawm). Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau nruab ib lub rooj sib nqus hlau nplaum thiab nruj me ntsis tswj thiab saib xyuas kev pub mis.
Cov dej noo hauv cov yas muaj qee yam cuam tshuam rau kev hnav ntawm cov ntsia hlau nto. Yog hais tias cov yas tsis tshem tawm tag nrho cov dej ua ntej txhaj tshuaj molding, thaum cov dej seem nkag mus rau hauv cov ntsia hlau compression seem, nws yuav tsim "steam particles" nrog kub thiab siab sib xyaw rau hauv cov yas molten ua ntej txhaj tshuaj. Nrog rau kev ua ntej ntawm cov ntsia hlau nyob rau hauv cov txheej txheem txhaj tshuaj, los ntawm homogenization seem mus rau lub taub hau ntsia hlau, cov "steam particles" yuav depressurized thiab nthuav dav thaum lub sij hawm txhaj tshuaj, xws li impurities zoo thiab nyuaj hais, uas yuav ua rau kev sib txhuam thiab puas. phab ntsa.
Tsis tas li ntawd, rau qee yam ntawm cov yas, nyob rau hauv qhov kub thiab txias, dej yuav dhau los ua cov khoom siv los txhawb kev tawg ntawm cov yas, tsim cov khoom tsis zoo uas tuaj yeem ua rau cov hlau ntog. Yog li ntawd, kev ua haujlwm kom qhuav ua ntej cov yas txhaj tshuaj molding tsis tsuas yog cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom, tab sis kuj cuam tshuam rau lub neej ua haujlwm ntawm cov ntsia hlau.
