1 Wopanda Poizoni Komanso Waukhondo.
Mamolekyu a PP-R ndi zinthu za kaboni ndi haidrojeni zokha, ndipo palibe zinthu zovulaza komanso zapoizoni.Ndi aukhondo komanso odalirika.Simagwiritsidwa ntchito kokha pamapaipi amadzi ozizira ndi otentha, komanso machitidwe amadzi akumwa oyera.
2 Kuteteza Kutentha Ndi Kupulumutsa Mphamvu.
The matenthedwe madutsidwe chitoliro PP-R ndi 0.21w/mk, amene ndi 1/200 yekha zitsulo chitoliro.
3 Kukana Kutentha Kwabwino.
The Vicat kufewetsa mfundo ya PP-R chitoliro ndi 131.5 ℃.Kutentha kwakukulu kogwira ntchito kumatha kufika 95 ℃, komwe kumatha kukwaniritsa zofunikira zamadzi otentha munyumba yopangira madzi ndi kachidindo.
4 Moyo Wautumiki Wautali.
Pansi pa ntchito kutentha 70 ℃ ndi kuthamanga ntchito (PN) wa 1.0MPa, moyo utumiki wa PP-R chitoliro akhoza kufika zaka zoposa 50 (malinga kuti zinthu chitoliro ayenera S3.2 ndi S2.5 mndandanda kapena Zambiri);pansi pa kutentha kwabwino (20 ℃) Moyo wautumiki ukhoza kufika zaka zoposa 100.
5 Kuyika Kosavuta Ndi Kulumikizana Kodalirika.
PP-R ili ndi ntchito yabwino yowotcherera.The mapaipi ndi zovekera akhoza chikugwirizana ndi otentha Sungunulani ndi electrofusion.Kuyikako ndikosavuta komanso zolumikizira ndizodalirika.Mphamvu ya mgwirizano ndi yaikulu kuposa mphamvu ya chitoliro palokha.
