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 ku 95 ℃, komwe kumatha kukwaniritsa zofunikira zamadzi otentha munyumba yopangira madzi ndi kachidindo.
4 Moyo Wautumiki Wautali.
Pansi pa ntchito kutentha kwa 70 ℃ ndi kuthamanga ntchito (PN) 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.
