Kodi ndi zinthu ziti zomwe ziyenera kuganiziridwa pokonza zinthu zopangidwa ndi polyethylene ya chlorinated?

Anthu ambiri sadziwa bwino polyethylene yokhala ndi chlorine, ndipo monga momwe dzinalo likusonyezera, anthu ambiri ayenera kungowona kuti ndi chinthu cha mankhwala. Ili ndi njira yotchedwa extrusion molding, yomwe ikadali yofunika kwambiri popanga. Ndiye lero, kodi tiyenera kusamala chiyani panthawi yopangira extrusion molding ya mankhwalawa? Chlorinated polyvinyl chloride

1. Mu njira yopangira mapaipi opangira zinthu zopangira ...

2. Kutentha kwa njira yopangira zinthu zopangidwa ndi chlorinated polyvinyl chloride ndi kokwera pang'ono kuposa kwa mapaipi a PVC. Koma ziyenera kudziwika kuti kusinthasintha kwa kutentha sikungapitirire ± 5 ℃.

3. Pakupanga mapaipi a CPVC, ngati pali kuzima kwa magetsi, kulephera kwa zida, zizindikiro za kuwonongeka kwa zinthu zosungunuka, kapena utsi wotuluka mkamwa mwa nkhungu, kupereka zinthu ku mbiya ya makina kuyenera kuyimitsidwa nthawi yomweyo. Utomoni wa PVC uyenera kugwiritsidwa ntchito kuchotsa zinthu zosungunuka za CPVC kuchokera mmbiya ya makina ndi nkhungu, kenako makinawo ayenera kuyimitsidwa kuti athetse mavuto.

4. Utomoni usanapangidwe, uyenera kuumitsidwa ndikutsukidwa mu bokosi loperekera kutentha kwa 80 ℃ kwa maola 2-4. Ngati kuli kofunikira, zinthu zopangira zosakaniza mwachangu ziyenera kusefedwanso kudzera mu sefa ya maukonde 40 kamodzi, kenako nkuyikidwa mu chosungira chotulutsira utomoni kuti zipangidwe.

5. Mpweya wa HCl womwe umatulutsidwa panthawi yosungunuka kwa CPVC ndi woopsa pa thanzi la anthu, ndipo chisamaliro chiyenera kuperekedwa pa mpweya wabwino womwe umapezeka m'malo opangira zinthu.

6. Mbiya ya makina otulutsira, zomangira, ndi zinthu zosungunuka zomwe zimadutsa mu nkhungu yopangira utomoni wa CPVC ziyenera kuchiritsidwa ndi mankhwala oletsa dzimbiri kuti ziwonjezere nthawi yogwira ntchito ya zida.

Mu njira yeniyeni yopangira, njira yopangira chlorinated polyvinyl chloride extrusion imakhala yovuta kwambiri. Zachidziwikire, ndikofunikira kusankha chinthu choyenera mukachigwiritsa ntchito nthawi zina, ndipo tiyenera kuganizira mosamala mlingo wa chinthucho kuti tigwiritse ntchito bwino.
