Ua rau cov ntsia hlau hnav ntawm ntsug txhaj tshuaj molding tshuab

Kev txhaj tshuaj system ntawm ntsug txhaj tshuaj molding tshuab yog tsim los ntawm cov khoom siv plasticizing thiab lub zog xa hluav taws xob. Cov cuab yeej txhaj tshuaj yas yas yog tsim los ntawm cov khoom noj khoom haus, ib lub cev, ib screw, thiab nozzle. Cov khoom siv hluav taws xob sib kis muaj xws li lub tog raj kheej txhaj tshuaj, ib qho kev txhaj tshuaj lub tog raj kheej txav thiab lub twj tso kua mis Tsav.

Cov txhaj tshuaj ntsia hlau yog ua haujlwm rau lub sijhawm ntev hauv qhov kub thiab txias, siab siab, high mechanical torque thiab kev sib txhuam ib puag ncig. Thawj ob peb yam yuav tsum tau ua los ntawm cov txheej txheem txheej txheem, thiab hnav los ntawm kev sib txhuam yog inevitable. Feem ntau, cov ntsia hlau tau raug rau saum npoo nitrogen. Kev kho tshuaj los ua kom lub ntsej muag hardness, yog, los txhim kho qhov hnav tsis kam, tab sis yog tias qhov ua rau hnav tsis quav ntsej thiab hnav tsis tau sim txo kom ntau li ntau tau, lub neej ua haujlwm ntawm cov ntsia hlau yuav inevitably txo qis heev.

Cov hauv qab no piav qhia txog qhov vim li cas rau kev hnav ntawm cov ntsia hlau txhaj tshuaj thiab cov txheej txheem los txo qhov hnav
1. Txhua lub yas muaj qhov ua haujlwm kub zoo tshaj plaws rau plasticization. Qhov ntsuas kub ntawm lub thoob yuav tsum tau tswj kom nyob ze rau qhov ntsuas kub no. Cov yas granular nkag mus rau hauv lub thoob los ntawm lub hopper, thiab yuav xub mus txog ntu pub mis, thiab kev sib txhuam qhuav yuav inevitably tshwm sim nyob rau hauv seem pub. Thaum cov plastics tsis rhuab txaus thiab melting tsis sib xws, Nws yog ib qho yooj yim los ua kom muaj zog hnav ntawm sab hauv phab ntsa ntawm lub thoob thiab qhov chaw ntawm cov ntsia hlau. Ib yam li ntawd, nyob rau hauv seem compression thiab seem homogenization. Yog hais tias lub xeev molten ntawm cov yas yog tsis zoo thiab tsis sib xws, nws tseem yuav ua rau kom hnav ntxiv.

2, qhov ceev yuav tsum tau kho kom raug. Vim tias qee cov yas tau ntxiv nrog cov tshuaj ntxiv, xws li iav fibers, minerals los yog lwm yam fillers, Kev sib txhuam ntawm cov khoom no ntawm cov ntaub ntawv hlau feem ntau yog ntau dua li cov yas molten. Thaum txhaj molding cov yas no, yog tias lawv tau ua nrog kev sib hloov ceev, nws yuav ua rau kom lub zog shearing rau cov yas, thiab tib lub sijhawm, qhov cuab lub zog yuav tsim ntau shredded fibers. Cov shredded fibers muaj cov ntse kawg, ua rau hnav Lub zog loj heev, thiab cov nyhuv scraping ntawm inorganic minerals thaum zawv zawg ntawm cov hlau nto ntawm kev kub ceev tsis yog me me, yog li qhov ceev yuav tsum tsis txhob hloov siab dhau.

Yuav ua li cas txhim kho lub neej ntawm kev txhaj tshuaj ntsia hlau
Cov ntsia hlau txhaj tshuaj tuaj yeem ua haujlwm tau ntev hauv qhov kub thiab txias, siab siab, high mechanical torque thiab kev sib txhuam ib puag ncig. Cov txheej txheem txheej txheem xav tau cov yam ntxwv no, thiab kev poob uas tshwm sim los ntawm kev sib txhuam yog inevitable. Feem ntau, txhaj tshuaj screws tau deg nitriding kev kho mob kom nce hardness, yog, los txhim kho hnav tsis kam. Txawm li cas los, yog tias qhov ua rau hnav tsis quav ntsej thiab qhov hnav tsis tuaj yeem txo qis, lub neej kev pab cuam ntawm txhaj tshuaj zawv plaub hau yuav luv heev. Cov laj thawj rau kev hnav ntawm cov ntsia hlau txhaj tshuaj thiab cov hau kev los txo qhov hnav tau piav qhia hauv qab no.

1.Txhua yam yas muaj ib qho zoo tagnrho plasticizing kub ntau yam. Kev ua haujlwm kub ntawm lub thoob yuav tsum tau tswj ze rau qhov ntsuas kub no. Granular yas nkag mus rau hauv lub thoob los ntawm lub hopper thiab thawj zaug mus txog qhov chaw pub. Kev sib txhuam qhuav yuav inevitably tshwm sim hauv thaj chaw pub. Yog hais tias cov yas no tsis muaj cua sov thiab melted unevenly, lawv yuav yooj yim ua rau hnav ntau dua rau ntawm phab ntsa sab hauv ntawm lub thoob thiab qhov chaw ntawm cov ntsia hlau txhaj tshuaj. Ib yam li ntawd, nyob rau hauv seem compression thiab seem homogenization, yog tias lub xeev molten ntawm cov yas yog chaotic thiab tsis sib xws, nws kuj tseem yuav ua rau muaj kev hnav ntau dua ntawm cov ntsia hlau txhaj tshuaj.
2. Qhov ceev yuav tsum tau kho kom haum. Vim tias qee cov yas tau ntxiv nrog cov tshuaj ntxiv, xws li iav fibers, minerals los yog lwm yam fillers. Kev sib txhuam ntawm cov tshuaj no ntawm cov ntaub ntawv hlau feem ntau yog ntau dua li cov yas molten. Thaum cov yas no txhaj tshuaj molded, yog tias lawv tau ua nyob rau hauv kev sib hloov ceev, thiab tib lub sij hawm nce lub zog shear ntawm cov yas, nws tseem yuav ua rau lub zog txhawb kom tsim tau ntau dua cov fibers. Cov chopped fiber muaj cov ntse kawg, uas tuaj yeem ua rau hnav ntawm cov ntsia hlau txhaj tshuaj. Thaum inorganic minerals swb ntawm cov hlau nto ntawm kev kub ceev, cov nyhuv scraping tsis yog me me, thiab nws tseem yuav ua rau hnav ntawm cov ntsia hlau txhaj tshuaj. Yog li ntawd, qhov ceev yuav tsum tsis txhob hloov siab heev.
