Mavuto ndi Mayankho a Kupanga PVC Transparent Sheet Extrusion Production

PVC pepala extrusion mzerePakuti kuwonekera bwino ndi imodzi mwa mitundu ikuluikulu ya PVC yolimba. Nthawi zambiri imapangidwa ndi PVC conical twin-screw extruder. Mavuto omwe amakumana nawo popanga zinthu ndi awa: thovu, ma crystal points ambiri, ndi mtundu wachikasu wa pepalalo. Kutengera ndi zomwe akatswiri amakampani omwe amakonza makina apeza, ndapeza zambiri, ndikuyembekeza kuti zingathandize anzanga.

Ngati pali cholakwika chilichonse, chonde musazengereze kundidziwitsa.
1. Vuto la mtundu wachikasu

Zifukwa ndi mayankho
Choyamba, kukhazikika kwa PVC palokha ndi koipa
Ngati ndi kampani yatsopano yopanga utomoni wa PVC, mwina kukhazikika kwa PVC yokha sikuli bwino, mutha kuyesa kusintha PVC. Komabe, ngakhale ndi kampani ya PVC yomwe yakhala ikugwiritsidwa ntchito nthawi zonse, ikhoza kukhala chifukwa cha utomoni wa PVC womwewo, chifukwa ngakhale PVC yopangidwa ndi kampani imodziyo, mtundu wake ungasiyane m'magulu osiyanasiyana.
Chachiwiri, chosakwanira chokhazikika
Chachitatu, pali vuto ndi chowongolera kutentha
Kutentha komwe kumawonetsedwa kumakhala kotsika kuposa kutentha kwenikweni, ndipo PVC imawola ndikukhala yachikasu ngati kutentha kuli kokwera kwambiri. Pakadali pano, ndikofunikira kuyang'ananso chowongolera kutentha kwa calibration. Njirayi ndi yosavuta kwambiri, ndipo thermometer ya mercury imagwiritsidwa ntchito poyesa. Pakupanga kwenikweni, chifukwa cha zifukwa monga ma thermocouple otayirira ndi zinthu zomatira, padzakhala kusiyana pakati pa kutentha komwe kumawonetsedwa ndi chowongolera kutentha ndi kutentha kwenikweni. Kuphatikiza apo, tikukulimbikitsani kugwiritsa ntchito chowongolera kutentha chapamwamba kwambiri.

2. Pepalali lili ndi thovu laling'ono la mpweya

①. Chinyezi chochuluka mu zinthu zopangira za PVC: Ngati zinthu zopangira zili zonyowa masiku amvula achilimwe, madzi sangatuluke mokwanira mu mbiya, ndipo kutentha kudzakula, kenako thovu la mpweya lidzapangidwa mu pepalalo.
②. Kuphatikiza apo, zowonjezera zitha kukhala ndi madzi ambiri. Mwachidule, yankho lingagwiritsidwe ntchito: Kutalikitsa nthawi yosakaniza ya chosakanizira chotentha moyenera, ndikugwiritsa ntchito chosakanizira choziziritsira. Chingathe kuchotsa bwino chinyezi kuchokera kuzinthu zopangira.
3. Chiwerengero cha mfundo za kristalo mu pepalalo chimaposa muyezo, womwe umadziwikanso kuti fisheye

Chifukwa chofala chomwe chimapangitsa kuti ma crystal points apangidwe ndi awa: tinthu tina ta PVC resin sitinapangidwe pulasitiki, kapena pulasitiki si yabwino. Zifukwa zomwe zinapangidwira ndi izi: mtundu wa PVC resin wokha si wabwino. Popanda kusintha PVC resin, yankho ndi ili:
Choyamba, onjezerani nthawi yosakaniza moyenera ndikuwonjezera kutentha kosakaniza kuti mulimbikitse kuyamwa kwa zowonjezera. Kuphatikiza apo, mayunitsi osakaniza abwino kwambiri amagwiritsidwa ntchito, ndipo mphamvu ya mayunitsi osakaniza pa zinthuyo siingasinthidwe.
Chachiwiri, zinthu zosakanizidwazo zitha kusiyidwa kwa theka la tsiku kapena tsiku, kuzisiya zitakhwima, kenako n’kuzigwiritsa ntchito.
Chachitatu, kutentha kokhazikika kwa mbiya kungawonjezedwe moyenera, liwiro la screw lingawonjezedwe, ndipo kuthamanga kwa mutu kungawonjezedwe kuti kuwonjezere magwiridwe antchito a pulasitiki.
Chachinayi, pankhani ya fomula, tiyenera kusankha mosamala zowonjezera zoyenera komanso kuchuluka kwa zowonjezera. Pakadali pano, msika wa zowonjezera uli wosokonezeka, ndipo mtundu wa malonda umasiyana kwambiri. Tiyenera kusankha mosamala ndikupeza mgwirizano wabwino pakati pa mtengo ndi magwiridwe antchito.

Mwachidule, zifukwa zomwe zili pamwambapa ziyenera kuganiziridwa mokwanira kuti tisankhe yankho labwino kwambiri. Mayankho ena ali ndi ubale wotsutsana, monga kukweza kutentha kungayambitse pepala kukhala lachikasu, kuwonjezera zinthu zina zokhazikika kungayambitse kukwera kwa mtengo, ndi zina zotero. Kungofufuza njira yopitira patsogolo.
