PPR mapaipi

Poyerekeza ndi mapaipi achitsulo, mapaipi a PPR ali ndi ubwino woyika mosavuta, kusungunula bwino kwa kutentha, komanso kukana dzimbiri.Ndi madzi athanzi komanso osagwirizana ndi chilengedwe komanso ndizomwe zimagwiritsidwa ntchito pamadzi pamsika.Mapaipi a PPR amapezeka makamaka mumitundu yotsatira, yoyera, Imvi, yobiriwira ndi curry mitundu, chifukwa chake pali kusiyana kumeneku makamaka chifukwa cha mitundu yosiyanasiyana ya masterbatches anawonjezera.

Kuphatikiza pa mawonekedwe a mapaipi apulasitiki wamba monga kulemera kopepuka, kukana kwa dzimbiri, kusakulitsa, komanso moyo wautali wautumiki, mapaipi a PP-R alinso ndi izi:

1 Zopanda poizoni komanso zaukhondo.
Mamolekyu a PP-R ndi zinthu za kaboni ndi haidrojeni zokha, ndipo palibe zinthu zovulaza komanso zapoizoni.Ndi aukhondo komanso odalirika.Sikuti amagwiritsidwa ntchito pa mapaipi amadzi ozizira ndi otentha okha, 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 wautali wautumiki.
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 Easy unsembe ndi kugwirizana odalirika.
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.

6 Zida zitha kubwezeretsedwanso.
Zinyalala za PP-R zimatsukidwa, kuthyoledwa, ndikusinthidwanso kuti zigwiritsidwe ntchito popanga mapaipi ndi zida.Kuchuluka kwa zida zobwezerezedwanso sikudutsa 10% ya ndalama zonse ndipo sizikhudza mtundu wazinthu.

kukhazikitsa

Zida zoyendetsedwa bwino, gulu la akatswiri ogulitsa, ndi ntchito zabwinoko zogulitsa pambuyo pake;Ndifenso banja lalikulu logwirizana, aliyense amamatira ku mtengo wa kampani "mgwirizano, kudzipereka, kulolerana" kwa Ubwino Wopambana wa Ifan wopanga mitundu yobiriwira 45 chigongono 20mm-110mm mitundu yonse ya ppr zoyikira mayina mwachangu ppr koyenera, Timatenga gawo lotsogola popereka makasitomala omwe ali ndi zinthu zapamwamba kwambiri opereka chithandizo komanso mitengo yampikisano.
Ubwino wabwino kwambiri, Pambuyo pazaka zambiri zachitukuko, tsopano tapanga luso lamphamvu pakukula kwazinthu zatsopano ndi machitidwe okhwima owongolera kuti atsimikizire mtundu wabwino kwambiri ndi ntchito.Ndi chithandizo chamakasitomala ambiri ogwirizana kwanthawi yayitali, mayankho athu amalandiridwa padziko lonse lapansi.
