PVC (Polyvinyl chloride) imagwira ntchito makamaka ngati chotenthetsera ndi choteteza m'chipinda.chingwe, ndipo mphamvu ya kutulutsa kwa tinthu ta PVC imakhudza mwachindunji momwe chingwecho chimagwiritsidwira ntchito. Zotsatirazi zikutchula mavuto asanu ndi limodzi omwe amapezeka nthawi zambiri a kutulutsa tinthu ta PVC, osavuta koma othandiza kwambiri!
01.Tinthu ta PVCchochitika choyaka moto panthawi yotulutsa.
1. Sikuluu imagwiritsidwa ntchito kwa nthawi yayitali, sikuluu siitsukidwa, ndipo zinthu zopsereza zomwe zasonkhanitsidwa zimachotsedwa; Chotsani sikuluu ndikuyeretsa bwino.
2. Nthawi yotenthetsera ndi yayitali kwambiri, tinthu ta PVC timakalamba, timapsa; Fupikitsani nthawi yotenthetsera, yang'anani ngati pali vuto ndi makina otenthetsera, ndi kukonza nthawi yake.
02. Tinthu ta PVC sitipangidwa pulasitiki.
1. Kutentha kuli kotsika kwambiri; Kuwonjezeka koyenera kungakhale.
2. Popanga pulasitiki, pulasitiki imasakanizidwa mosagwirizana kapena zimakhala zovuta kuyika tinthu tating'onoting'ono mu pulasitiki; Chovala cha nkhungu chimatha kukhala ndi zinthu zazing'ono zomwe zimathandiza kuti pakamwa pa guluu pakhale mphamvu.
03. Tulutsani makulidwe osafanana ndi mawonekedwe a slub
1. Chifukwa cha kusakhazikika kwa zomangira ndi kukoka, zomwe zimapangitsa kuti makulidwe a chinthucho asafanane, chifukwa cha mavuto a mphete yomangika, nsungwi yopangidwa mosavuta, nkhungu ndi yaying'ono kwambiri, kapena kusintha kwa mainchesi a chingwe, zomwe zimapangitsa kuti makulidwe asinthe.
2. Nthawi zambiri yang'anani mphamvu ya chipangizo chokokera, zomangira, ndi mphamvu yonyamula kapena liwiro lake, kusintha kwa nthawi yake; Chifaniziro chofananacho chiyenera kukhala choyenera kuti guluu asatsanulire; Yang'anirani kusintha kwa milingo yakunja pafupipafupi.
04.Zipangizo za chingwema pores ndi thovu la extrusion
1. Choyambitsidwa ndi kutentha kwambiri m'deralo; Zapezeka kuti kutentha kuyenera kusinthidwa pakapita nthawi ndikuwongoleredwa mosamala.
2. Pulasitiki yoyambitsidwa ndi chinyezi kapena madzi; Yapezeka kuti iyenera kuyimitsidwa nthawi ndi chinyezi chonse.
3. Chipangizo chowumitsira chiyenera kuwonjezeredwa; Umitsani zinthuzo musanagwiritse ntchito.
4. Chimake cha waya chiyenera kutenthedwa kaye ngati chili chonyowa.
05. Kukwanira kwa zinthu zotulutsira chingwe sikwabwino
1. Kuwongolera kutentha kochepa, kusapanga pulasitiki bwino; Yang'anirani kutentha mosamala malinga ndi momwe zinthu zilili.
2. Kuwonongeka kwa nkhungu; Sinthani kapena chotsani kuwonongeka kwa nkhungu.
3. Kutentha kochepa kwa mutu, kuuma kwa pulasitiki sikwabwino; Kwezani kutentha kwa mutu moyenera.
06. Malo otulutsira tinthu ta PVC si abwino
1. Utomoni womwe ndi wovuta kuupanga kukhala pulasitiki umatulutsidwa popanda kuupanga kukhala pulasitiki, zomwe zimapangitsa kuti pakhale mfundo zazing'ono za kristalo ndi tinthu tating'onoting'ono pamwamba, zomwe zimafalikira mozungulira pamwamba; Kutentha kuyenera kuwonjezeredwa moyenera kapena liwiro la chingwe chokokera ndi liwiro la screw ziyenera kuchepetsedwa.
2. Mukawonjezera zinthu, zinthu zosafunika zimasakanizidwa ndi pamwamba pa zinthu zosafunika; Mukawonjezera zinthu zosafunika, zinthu zosafunika ziyenera kutetezedwa kuti zisasakanizidwe, ndipo zinthu zosafunika ziyenera kutsukidwa nthawi yomweyo ndipo guluu wokumbukira screw ayenera kuchotsedwa.
3. Pamene pakati pa chingwe ndi wolemera kwambiri, mphamvu yolipirira imakhala yochepa, ndipo kuzizira sikuli bwino, pamwamba pa pulasitiki pamakhala kosavuta kukwinya; Choyamba chiyenera kuwonjezera mphamvu, ndipo chachiwiri chiyenera kuchepetsa liwiro la chingwe chokokera kuti chitsimikizire nthawi yozizira.
