PVC chingwe zinthu amapangidwa polyvinyl kolorayidi monga utomoni woyambira, kuwonjezera stabilizers, lubricant ndi inorganic.

fillers, etc., kudzera kusakaniza, kneading ndi extrusion.Ngakhale kuti ntchito yake yapakati ndiyambiri komanso

osati zachilengedwe, mtengo wake ndi wotsika ndipo ndondomekoyi ndi yosavuta;PVC chingwe zinthu akadali mmodzi wa kwambiri

zida zogwiritsa ntchito chingwe.

Pamene PVC chingwe chuma extruded, mavuto otsatirawa akhoza kukumana.Lero, Qingdao Sainuo

phula la polyethylenewopanga adzakambirana nanu mwatsatanetsatane momwe izi zimachitikira:

1. Kuwotcha chodabwitsa pa extrusion PVC chingwe chuma

Kutuluka kwa nkhungu kumakhala ndi utsi wambiri, fungo lopweteka kwambiri komanso phokoso lopweteka;pali particles zotentha pamwamba pake

pulasitiki pamwamba.

chifukwa chanji?Kodi kusintha?

(1) Ngati zomangirazo zigwiritsidwa ntchito kwa nthawi yayitali, zomangirazo sizitsukidwa, ndipo zowotcha zomwe zasonkhanitsidwa zimabweretsedwa.

kunja;chotsani wononga ndikuyeretsa bwino.

(2) Kutentha nthawi yayitali kwambiri, pulasitiki imakalamba ndikuwotcha;kufupikitsa Kutentha nthawi, fufuzani ngati Kutentha

dongosolo ali ndi mavuto aliwonse, ndi kukonza mu nthawi.

2. Osauka extrusion ndi plasticization wa PVC chingwe chuma

Pamwamba pa pulasitiki pali chodabwitsa cha khungu la achule, pamwamba pake ndi zakuda, ndipo pali ming'alu yaying'ono kapena yaying'ono.

particles zomwe sizinapangidwe pulasitiki.Pali chizindikiro chowonekera pamsoko.

chifukwa chanji?Kodi kusintha?

(1) Kutentha kumakhala kotsika kwambiri;ingowonjezerani moyenera.

(2) Popanga granulating, pulasitiki imasakanizidwa mosagwirizana kapena pali tinthu tating'onoting'ono tovuta kuyikapo pulasitiki.

pulasitiki;manja a nkhungu akhoza kukhala ochepa moyenerera kuti awonjezere kukakamiza kwa glue.

(3) Kuthamanga kwa wononga ndi kukoka ndikothamanga kwambiri, ndipo pulasitikiyo sinapangidwe kwathunthu;moyenerera wodekha

tsitsani liwiro kuti muwonjezere nthawi yotentha komanso yopangira pulasitiki kuti mupititse patsogolo mphamvu ya pulasitiki.

(4) Mavuto akuthupi;Sinthani zida

3. Chingwe zakuthupi extruded pores ndi thovu

chifukwa chanji?Kodi kusintha?

(1) Zimayamba chifukwa cha kuwongolera kwapamwamba kwambiri komweko;amapezeka kuti kutentha kuyenera kusinthidwa ndi

kulamulidwa mosamalitsa munthawi yake.

(2) pulasitiki yonyowa kapena madzi oyambitsa;ngati chapezeka, siyani kuchigwiritsa ntchito ndikukhetsa zinthu zonyowa.

(3) Chipangizo chowumitsira zinthu chiyenera kuwonjezeredwa;zinthuzo ziyenera kugwiritsidwa ntchito pambuyo kuyanika.

(4) Pakatikati payenera kutenthedwa kale ngati panyowa.
