Muab faib ua plaub pawg: 1, extrusion: yas ua, kuj hu ua extrusion, uas tsis yog-roj hmab extrusion tshuab nyob rau hauv cov kev siv ntawm hydraulic siab nyob rau hauv lub puab nws tus kheej, hais tias extrusion tawm ntawm siab. Hais txog cov ntaub ntawv uas los ntawm lub extruder chim thiab lub luag hauj lwm ntawm lub ntsia hlau, thaum los ntawm cov thermoplastic, thaum lub sij hawm cov ntsia hlau pem hauv ntej, tas mus li los ntawm lub qhov ntswg thiab ua ib tug ntau yam ntawm tus ntoo khaub lig-section cov khoom los yog semi-tiav lawm cov khoom, ib tug ua txoj kev. 2, txhaj tshuaj molding: kuj hu ua txhaj molding, nws yog ib tug txhaj molding thiab molding txoj kev. Qhov zoo ntawm cov kev txhaj tshuaj molding yog cov ntau lawm ceev, high efficiency, lub lag luam yuav tsum cia, xim ntau yam, tus duab yuav ua tau los ntawm tej yam yooj yim rau txoj, loj yuav ua tau loj me me, thiab cov khoom loj yog muaj tseeb, ib qho yooj yim los hloov lub khoom, yuav tsim txoj Yam, txhaj tshuaj molding rau ib tug loj tus naj npawb ntawm ntau lawm thiab zoo ntawm complex cov khoom xws li molding processing.Plastic Qhov Manufacturing

1. Cov tsim txoj kev ntawm yas khoom, uas yog, lub molding txheej txheem ntawm yas hwj, yog hais txog mus rau lub hluavtaws cob Hoobkas ua los ntawm polymer ua los ntawm zaum kawg yas khoom txheej txheem. 2. ua txoj kev (thiab yas ua) muaj xws li: compression molding (extrusion molding), extrusion (extrusion), txhaj tshuaj molding (txhaj tshuaj molding), tshuab molding (hollow molding), dov thiab thiaj li nyob. Xav paub tsim txoj kev: compression molding: molding los yog pressing molding. Compression yog tsuas yog siv rau phenolic cob, urea-formaldehyde cob, unsaturated polyester cob thiab lwm yam thermosetting yas molding. Extrusion: Extrusion yog siv tus extruder (extruder) tujtaws sov lub cob los ntawm cov pwm, extrusion ntawm lub Desired zoo ntawm cov khoom. Extrusion tej zaum kuj thermosetting yas molding, thiab yuav siv tau rau ua npuas ncauj Ntawm molding. Extrusion yog lub zoo dua ntawm extruding ib tug ntau yam ntawm cov duab ntawm cov khoom, siab ntau lawm efficiency, yuav cia li, tas mus li lawm; lub disadvantage yog tias thermosetting yas yuav tsis tau lug siv nyob rau hauv no txoj kev ntawm kev ua, cov khoom loj nws tsis ncaj ncees. Txhaj Tshuaj Molding: Txhaj Tshuaj Molding. Txhaj molding yog siv cov txhaj tshuaj molding tshuab (los yog txhaj tshuab) yuav thermoplastic qhuav nyob rau hauv kub siab mus rau hauv lub puab los ntawm txias, tua cov khoom tau los ntawm kev txhaj tshuaj molding kuj yuav siv tau rau thermosetting yas thiab ua npuas ncauj molding. Qhov zoo ntawm cov kev txhaj tshuaj molding yog lawm ceev, high efficiency, lub lag luam yuav tsum cia, muaj peev xwm puab lub complex puab ntawm lub qhov chaw, tshwj xeeb tshaj yog rau cov loj ntau lawm. Tsis zoo yog tus nqi ntawm cov khoom thiab tuaj pwm, txhaj tshuaj molding tshuab ntxuav ntau difficult.Plastic Qhov Manufacturing

Tshuab molding: hollow tshuab molding los yog hollow molding. Tshuab molding yog ib txoj kev ntawm Inflating ib tug kub cob parison uas yog kaw nyob rau hauv ib tug pwm mus rau hauv ib tug hollow khoom los ntawm txoj kev lub siab ntawm compressed cua. Lub tshuab molding muaj ob tshuab zaj duab xis thiab tshuab hollow khoom. Zaj duab xis khoom, tag nrho cov hom ntawm lub fwj, tej kas tham, huam thiab cov me nyuam cov khoom ua si, xws li khoom ua si Lub calendering yog lub processing ntawm lub cob thiab ntau yam additives los ntawm cov kev kho mob (kneading, pom, thiab lwm yam) thiab ces ua mus rau hauv ib zaj duab xis los yog daim ntawv los ntawm cov kis ntawm ob los yog ntau tshaj diametrically opposed calender yob ntawm cov calender, ua raws li los ntawm tshwv tawm los ntawm lub calender yob, Thiab ces los ntawm txias ib tug molding txoj kev. Rolling yog tsuas yog siv rau lub molding txoj kev polyvinyl tshuaj dawb cob, yuav ua tau nyias zaj duab xis, daim ntawv, ntawv, khoom cua tawv, pem teb pobzeb thiab lwm yam khoom. Ua Npuas Ncauj ntaub ntawv (PVC, PE thiab PS, etc.) los ntawm kev ntxiv rau qhov tsim nyog blowing neeg sawv cev, thiaj li hais tias cov txheej txheem ntawm yas microporous qauv. Yuav luag tag nrho cov ntawm cov thermosetting thiab thermoplastics yuav ua los ntawm ua npuas ncauj. Raws li cov cell qauv yog muab faib mus rau hauv qhib-cell ua npuas ncauj (xav tias feem ntau ntawm cov pores kev cob cog rua rau txhua lwm yam) thiab kaw-cell ua npuas ncauj (feem coob ntawm cov pores yog cais los ntawm txhua lwm yam), uas yog tsuas yog los ntawm tus raug qauv (muab faib mus rau hauv tshuaj ua npuas ncauj, Thiab cov neeg kho tshuab foaming) .Plastic Qhov Manufacturing
