Paipu polyvinyl kiloraidi, tun nperare pvc pipe, jẹ ọpọn ti pilasitik giga ti o gbona ti o ṣẹda nipasẹ polymerization ti vinyl choride monomer, mu polyvinyl kiloraidi (PVC) RESINS gẹgẹbi ohun elo aise akọkọ, ṣafikun aṣoju antiaging ti o yẹ, aṣoju atunṣe awọn ohun-ini. ati be be lo, awọn ohun elo lara nipasẹ imuposi bi dapọ, calendering, igbale formings.

Pvc pipe resistance to ipata jẹ lagbara, o ti wa ni imora lati wa ni rọrun lati, PVC ni o ni gidigidi lagbara resistibility si oxygenant, reductive oluranlowo ati ki o lagbara acid.But o le jẹ corroded ati awọn tun inapplicable ayeye kíkàn pẹlu aromatic hydrocarbon, chlorinated hydrocarbon bi awọn vitriol. epo, ogidi nitric acid nipasẹ ipon oxidizing acid.

Ṣugbọn, paipu pvc, ni pataki UPVC pipe resistance toheat ko dara, ati agbara fifẹ ayika dinku diẹ sii ju 60 ℃, ati labẹ agbegbe iwọn otutu kekere, Vybak omi titu resistance si ipaya ipa n dinku.Ni gbigbe, fifi sori ẹrọ ati ilana lilo, irọrun wa brittle. rupture;Ni afikun, iṣẹ ṣiṣe ti pvc pipe duro awọn ipaya tun jẹ talaka.

Iru awọn paipu polychlorethylene tenacity giga, lati ṣe nipasẹ paati ti apakan iwuwo atẹle:
