PVC chitoliro akhoza kugawidwa mu zofewa PVC ndi okhwima PVC.PVC yolimba imakhala pafupifupi 2/3

pamsika, PVC yofewa imakhala pafupifupi 1/3 ya msika.Mapaipi ofewa a PVC ndi

kawirikawiriamagwiritsidwa ntchito pansi, denga ndi zikopa, Koma chifukwa PVC yofewa imakhala

plasticizers (omwendi kusiyana pakati pa PVC yofewa ndi PVC yolimba) , thupi lake

katundu ndi osauka (kwaMwachitsanzo, mapaipi omwe amafunikira kupirira kuchuluka kwa madzi

pressure), PVC yofewa sioyenera kugwiritsidwa ntchito) , kotero kuchuluka kwake kwa ntchito kumakhala kochepa.

PVC yolimba ilibe plasticizer, kotero ndiyosavuta kupanga komanso imakhala ndi thupi labwino

katundu,kotero ili ndi chitukuko chachikulu komanso mtengo wogwiritsa ntchito.Zowonjezera zingapo, monga

stabilizers ndimapulasitiki, ayenera kuwonjezeredwa ku zipangizo za polyvinyl chloride.Ngati zonse zikugwiritsidwa ntchito

zachilengedwezowonjezera, PVC chitoliro si poizoni, zoipa ndi zachilengedwe

mankhwala.Naziubwino ndi kuipa:

1. Ubwino wa chitoliro cha PVC:

(1) Mphamvu yabwino komanso yopondereza: koma osati yosinthika ngati mapaipi ena apulasitiki.

(2) PVC chitoliro otsika madzimadzi kukana: PVC chitoliro khoma ndi yosalala kwambiri, pafupifupi palibe kukana madzimadzi.

Chigawo cha roughness ndi 0.009 yokha.Mphamvu yake yonyamula madzi ndi 20% kuposa pamenepo

Chitoliro chachitsulo chofananacho ndi 40% kuposa chitoliro cha konkire.

(3) Zimbiri zabwino kwambiri komanso kukana mankhwala: mapaipi a PVC ali ndi kukana kwa asidi,

kukana kwa alkali ndi kukana dzimbiri, osakhudzidwa ndi madzi amvula ndi nthaka pH.Ayi

Chithandizo cha anticorrosion chimafunika pakuyika mapaipi.

(4) Ndi kuthina bwino madzi: PVC chitoliro unsembe, kaya kudzera chomangira kapena labala

kulumikiza mphete, kukhala ndi madzi othina bwino.

(5) Umboni wa kuluma: Machubu a PVC si gwero lazakudya chifukwa chake samawononga ndi

makoswe.Malinga ndi kuyesa kochitidwa ndi National Institutes of Health ku Michigan, makoswe

musalumidwe mapaipi a PVC.

(6) Kuyesa kwa Magwiridwe: kuchiritsa nthawi, kuchepa, mphamvu yogawanitsa, zinthu zolimba, peel

mphamvu, kukhazikika kwa kutentha, moyo wa alumali, moyo wosungirako, kumasulidwa kwa zinthu zoopsa.

2. Kuipa kwa mapaipi a PVC:

(1) Osayenerera chitoliro cha madzi otentha, osayenera chitoliro cha madzi akumwa mwachindunji.

(2) PVC chitoliro n'zosavuta embrittlement pamene anakhudzidwa

(3) Chitoliro china chotsika kwambiri cha PVC popanga pulasitiki wowonjezera wabodza, chidzayambitsa

kuipitsidwa kwapakatikati, kufupikitsa kwambiri nthawi yokalamba ya chitoliro cha PVC.
