PPR mapaipi

Kuenzaniswa nemapombi esimbi, mapaipi ePPR ane zvakanakira kuisirwa zviri nyore, zvirinani kupisa kwemafuta, uye kuramba kune ngura. Iyo ine hutano uye inoshamwaridzana nemamiriro ekunze ekupa mvura zvinhu uye zvakare ndiyo yakajairika mvura chigadzirwa pamusika. PPR mapaipi anonyanya kuwanikwa mune anotevera mavara, machena, Grey, girini uye curry mavara, nei paine musiyano uyu unonyanya kukonzerwa neakasiyana mavara masterbatches akawedzerwa.

Pamusoro pehunhu hwemapombi epurasitiki akajairwa senge huremu huremu, corrosion resistance, kusakwira, uye hupenyu hurefu hwesevhisi, PP-R mapaipi anewo anotevera hunhu:

1 Non-chepfu uye hutsanana.
Iwo mbishi zvinhu mamorekuru ePP-R anongova kabhoni uye hydrogen zvinhu, uye hapana zvinokuvadza uye zvine chepfu zvinhu. Ihwo hutsanana uye hwakavimbika. Haisi kungoshandiswa chete kumvura inotonhora uye inopisa mvura, asiwo kune yakachena yekunwa masisitimu.

2 Kuchengetedza kupisa uye kuchengetedza simba.
Iyo inopisa conductivity yePP-R pombi ndeye 0.21w / mk, iyo inongova 1/200 yepombi yesimbi.

3 Zvirinani kupisa kusagadzikana.
Iyo Vicat yekunyorovesa poindi yePP-R pombi ndeye 131.5 ℃. Iyo yakanyanya tembiricha yekushanda inogona kusvika 95 ℃, iyo inogona kusangana nezvinodiwa zveiyo inopisa mvura system mune yekuvaka mvura yekugovera uye yekudonha kodhi.

4Upenyu hurefu hwebasa.
Pasi pemamiriro ekushanda tembiricha ye70 ℃ uye kushanda kumanikidza (PN) ye1.0MPa, hupenyu hwesevhisi yePP-R pombi inogona kusvika makore anopfuura makumi mashanu (chero bedzi iyo pombi zvinhu inofanira kuva S3.2 uye S2.5 akatevedzana kana kupfuura); pasi peyakajairika tembiricha (20 ℃) ​​Hupenyu hwesevhisi hunogona kusvika kupfuura makore zana.

5 Easy kugadzwa uye yakavimbika kubatana.
PP-R ine yakanaka welding performance. Iyo mapaipi uye mafittings anogona kubatanidzwa nekupisa kunyunguduka uye electrofusion. Kuiswa kwacho kuri nyore uye majoini akavimbika. Simba rejojo ​​rakakura kudarika simba repombi pachayo.

6 Zvishandiso zvinogona kushandiswazve.
Iyo PP-R tsvina inocheneswa, yakaputsika, uye inodzokororwa kuti ishandiswe mukugadzirwa kwepombi nekuisa. Huwandu hwezvinhu zvakadzokororwa hahupfuuri 10% yehuwandu hwese uye hahuna kukanganisa kunaka kwechigadzirwa.
