Munguva yepombi extrusion process, gasi inoda kubuda kubva mukunyungudika. Kana magasi aya asingakwanise kubuda nenguva, kuremara kwakadai semapores, mabubbles, uye kupusa kwepasi kunogona kuoneka pamusoro kana mukati mezvigadzirwa zvepombi, zvichikanganisa zvakanyanya chimiro chemuviri uye chemichina, zvimiro zvemakemikari, uye pombi yemagetsi.
Kune 1 kusvika 2 maventi pakati pechiteshi chekudyisa uye musoro wemuchina kuti ubvise hunyoro uye zvimwe zvinoputika muzvakanyungudutswa zvakanyungudutswa. Zvisinei, mamwe mazarure emasilinda esimbi anowanzoonekwa. Dambudziko rinowanzoitika nderokuburitsa zvinhu kubva pachiteshi chekuburitsa. Chinhu chidiki chezvinhu chinozokanganisa kuburitswa kwemavolatiles uye kukanganisa kunaka kwechigadzirwa; huwandu hukuru hwezvinhu huchavharira chiteshi chekuburitsa uye kunyange kukonzera downtime.
Kazhinji, pane zvikonzero zviviri zvekudyisa pombi extruder. Imwe ndeye isinganzwisisike screw dhizaini, iyo inoita kuti zvinhu zviyerere kumashure pachiteshi chekuburitsa; imwe yacho idhizaini yakatetepa yechiteshi chemagetsi. Iyo yakanyungudutswa "inoturikwa" kana ichipfuura nepachiteshi chemagetsi.

Chekutanga pane zvese, iwe unogona kuona kana zvinhu zviri muscrew zvinoyerera zvichidzoka kubva kumhepo. Mune akawanda anofemerwa extruder, iwe unogona kuona iyo yakanyunguduka ichienda kumberi mune screw. Mumamiriro ezvinhu akajairika, dhigirii rekuzadza screw groove nezvinhu hazvipfuuri 50%. Kana ikapfuura, inokanganisa mhedzisiro uye inoita kuti jira ribudise pachena pachiteshi chekuburitsa; kana iri pasi pe50%, screw inogona kushanda kazhinji. Zvinhu zvisina kunaka zvinogona kukonzeresa nekusanzwisisika dhizaini yechiteshi chekuburitsa kana shunt chikamu.

Zvinhu Zvinokanganisa Kunzvenga Kwezvinhu zvePipe Extruder uye Solutions

1. Screw factor
Exhaust screw inonyanya kutora akawanda-stage dhizaini. Iyi dhizaini yakanakira ndeyokuti chiteshi chekuburitsa chiri pasi pekumanikidzwa kwakajairwa, uye zvinhu zvacho hazvibudi. Extruder ine vent imwe inoda 2-stage screw, uye mavhavha maviri anoda 3-stage screw. Nhanho imwe neimwe ine chikamu chepakati chekumanikidza, chikamu chekumanikidza, uye chikamu chekuyera. Chikamu chekutanga chenhanho yekutanga ndiyo yakajairwa kudzvinyirirwa chikamu chekudyisa, uye nhanho yechipiri ndiyo yakajairwa kumanikidza exhaust chikamu, kunova ndiko kune chiteshi chemagetsi.
Kune iyo screw dhizaini yeiyo yakavharwa extruder, kune matambudziko maviri: kana zvinhu zvasvika pachikamu chemhepo, zvinhu zvacho zvinofanirwa kunyungudika zvachose kuti zviburitse zvinoputika; chechipiri, chiyero chekudyisa chechipiri-chechipiri screw inofanira kunge yakakosha kudarika iyo yekutanga-stage screw kuti iite The screw groove pakutanga kwechikamu chechipiri haina kukwana, kuitira kuti mhepo inobuda inogona kuchengetedza zvakajairika.
Kana iyo chiyero chekudya cheiyo nhanho yekutanga screw yakanyanya kukosha kupfuura iyo yechipiri-nhanho screw, iyo inonyungudika mu extruder inoyerera ichidzoka. Kugadzirisa dambudziko iri, zvinodikanwa kuderedza kuwanda kwekudya kwechikamu chekutanga kana kuwedzera chikamu chechipiri chekudya.

2. Maitiro ekugadzirisa
Iyo inokurumidza uye iri nyore nzira yekugadzirisa dambudziko ndeyekuchinja maitiro ekuita. Semuyenzaniso, ndiri kuwedzera kukwesha uye kugerwa kwesimbi uye silinda yesimbi kana sikuruu uye kuwedzera kukwenya kana viscosity padivi pesilinda yesimbi kuti ndivandudze vhoriyamu yekutumira.

3. Chiteshi chemvura
Kana iyo screw pachiteshi chekuburitsa inongozadzwa zvishoma uye chiteshi chemagetsi chichiri kudyisa zvinhu, pane rimwe dambudziko nedhizaini yekuburitsa. Chiteshi chekubuditsa chinofanirwa kuve chakapamhama kupfuura kurukova kuti ive nechokwadi chekuti kunyungudika hakuvharise chiteshi chekuburitsa. Panguva imwe chete, kuvhurwa kwechiteshi chekupedza hachifaniri kunge chakakura, chinogona kuderedza nguva yekugara yekunyunguduka uye nguva yekuwedzera yekuyerera kwezvinhu.
Semugadziri wepombi extruder, chiitiko chaJinwei ndeichi: Kana iyo siuru yemhepo iri kunze kweiyo zvinhu zvine chekuita neextrusion process, kuita kwepurasitiki, uye dhizaini yescrew uye vent. Naizvozvo, mugadziri ari kushandisa vented extruder. Paunenge uchisiya muchina wekugadzira uye kugadzirisa, zvinodikanwa kuti unzwisise tekinoroji yekugadzira, resin maitiro, uye mashandiro emidziyo kuita kuti iyo yakavharwa extruder inowanzoshanda uye yakagadzikana.
