Kodi tiyenera kulabadira chiyani mu akamaumba extrusion wa chlorinated polyethylene zipangizo?

Anthu ambiri sadziwa za chlorinated polyethylene, ndipo monga momwe dzinalo likusonyezera, anthu ambiri ayenera kungowona kuti ndi mankhwala. Ili ndi njira yotchedwa extrusion molding, yomwe ndi yofunika kwambiri pakupanga. Kotero lero, kodi tiyenera kulabadira chiyani pa extrusion akamaumba ndondomeko mankhwala? Chlorinated polyvinyl chloride

1. Muzopangira zopangira zopangira mapaipi, chidwi chiyenera kuperekedwa pa kusankha kwa stabilizers ndi zina zothandizira kukonza, ndi cholinga chachikulu pa kupititsa patsogolo kusungunuka kwa madzi osungunuka ndi kupititsa patsogolo kukhazikika kwa kutentha kwa zipangizo. Ngati ndi kotheka, zida za fomula zitha kusakanikirana poyamba, ndipo zitsanzo zing'onozing'ono zitha kutengedwa kukayezetsa. Ngati palibe chodziwikiratu kusinthika kapena kuwonongeka chodabwitsa mu 230 ℃ perekani bokosi kwa maola 2, izo zikusonyeza kuti kusankha zipangizo wothandiza ndi wololera.

2. The extrusion akamaumba ndondomeko kutentha kwa chlorinated polyvinyl kolorayidi zipangizo ndi apamwamba pang'ono kuposa mapaipi PVC. Koma tisaiwale kuti kutentha ulamuliro kusinthasintha si upambana ± 5 ℃.

3. Pakupanga mapaipi a CPVC, ngati pali kuzima kwa magetsi, kulephera kwa zida, zizindikiro za kuwonongeka kwa zinthu zosungunuka, kapena utsi wotuluka pakamwa pa nkhungu, kupereka kwa zipangizo ku mbiya yamakina kuyenera kuyimitsidwa nthawi yomweyo. PVC utomoni ayenera kugwiritsidwa ntchito kuchotsa CPVC kusungunuka zinthu mu mbiya makina ndi nkhungu, ndiyeno makina ayenera kuyimitsidwa kuthetsa mavuto.

4. Utomoni usanapangidwe, uyenera kuumitsidwa ndikusungidwa mu bokosi la 80 ℃ kwa maola 2-4. Ngati ndi kotheka, mkulu-liwiro osakaniza zopangira ayeneranso sieved kupyolera 40 mauna sieve kamodzi, ndiyeno kuika mu extruder hopper kupanga.

5. Mpweya wa HCl wotulutsidwa panthawi ya kuwonongeka kwa CPVC kusungunuka ndi wovulaza thanzi laumunthu, ndipo chidwi chiyenera kuperekedwa ku mpweya wabwino mu msonkhano wopanga.

6. The extrusion machine mbiya, screw, ndi zinthu zosungunula akuyenda mu nkhungu akamaumba ntchito popanga CPVC utomoni ayenera kukumana odana ndi dzimbiri mankhwala kuwonjezera moyo utumiki wa zida zida.

Mu ndondomeko yeniyeni kupanga, extrusion akamaumba ndondomeko chlorinated polyvinyl kolorayidi akadali zovuta. Inde, ndikofunikira kusankha mankhwala oyenera mukamagwiritsa ntchito nthawi zina, ndipo tiyenera kuganizira mozama za mlingo wa mankhwalawa kuti tithandizire kugwiritsa ntchito bwino.
