Amapayipi e-PPR

Uma kuqhathaniswa namapayipi ensimbi, amapayipi e-PPR anezinzuzo zokufakwa okulula, ukuvikela ukushisa okungcono, kanye nokumelana nokugqwala. Kuyizinto zokunikeza amanzi ezinempilo futhi ezinobungani nemvelo futhi futhi kungumkhiqizo ojwayelekile wokunikeza amanzi emakethe. Amapayipi e-PPR atholakala kakhulu ngemibala elandelayo, emhlophe, empunga, eluhlaza kanye ne-curry, kungani kukhona lo mehluko ubangelwa kakhulu yimibala ehlukene ye-masterbatches engeziwe.

Ngaphezu kwezici zamapayipi epulasitiki ajwayelekile njengesisindo esincane, ukumelana nokugqwala, ukungakhuli, kanye nokuphila isikhathi eside, amapayipi e-PP-R nawo anezici ezilandelayo eziyinhloko:

1 Ayinabo ubuthi futhi ayihlanzekile.
Ama-molecule e-PP-R ayizinto zekhabhoni ne-hydrogen kuphela, futhi azikho izinto eziyingozi nezinobuthi. Ahlanzekile futhi athembekile. Akusetshenziswa nje kuphela emipayipini yamanzi abandayo nashisayo, kodwa futhi nasezinhlelweni zamanzi okuphuza ahlanzekile.

2 Ukulondolozwa kokushisa nokonga amandla.
Ukushisa kwepayipi le-PP-R kungu-0.21w/mk, okuyi-1/200 kuphela yepayipi lensimbi.

3 Ukumelana nokushisa okungcono.
Indawo yokuthambisa i-Vicat yepayipi le-PP-R ingu-131.5℃. Izinga lokushisa eliphezulu lokusebenza lingafinyelela ku-95℃, okungahlangabezana nezidingo zesistimu yamanzi ashisayo kukhodi yokuphakelwa kwamanzi neyokukhipha amanzi esakhiweni.

4Impilo yenkonzo ende.
Ngaphansi kwezimo zokushisa kokusebenza okungu-70℃ kanye nengcindezi yokusebenza (PN) engu-1.0MPa, impilo yokusebenza yepayipi le-PP-R ingafinyelela eminyakeni engaphezu kwengu-50 (uma nje izinto zepayipi kumele zibe uchungechunge lwe-S3.2 kanye ne-S2.5 noma ngaphezulu); ngaphansi kokushisa okuvamile (20℃) impilo yokusebenza ingafinyelela eminyakeni engaphezu kweyi-100.

5 Ukufakwa okulula nokuxhumeka okuthembekile.
I-PP-R isebenza kahle kakhulu ekushiseni. Amapayipi nezinto zokufaka zingaxhunywa ngokuncibilika okushisayo kanye nokuhlanganiswa kwe-electro. Ukufakwa kulula futhi amalunga athembekile. Amandla elungani makhulu kunamandla epayipi uqobo.

Izinto ezi-6 zingaphinde zisetshenziswe.
Imfucuza ye-PP-R iyahlanzwa, iphulwe, futhi isetshenziswe kabusha ukuze isetshenziswe ekukhiqizweni kwamapayipi kanye nokufakwa. Inani lezinto ezisetshenziswe kabusha alidluli u-10% wenani eliphelele futhi alithinti ikhwalithi yomkhiqizo.

ukufakwa

Sithatha “okunobungane kumakhasimende, okugxile ekhwalithini, okuhlanganisiwe, okusungula izinto ezintsha” njengezinhloso. “Iqiniso nokwethembeka” kuyindlela yethu yokuphatha efanele umhlinzeki wegolide waseShayina we-Brass Insert enombala wethusi we-PPR, Abangane bamukelekile abavela emhlabeni wonke beze ukuzobona, beze ngesandla futhi bexoxisana.
Umhlinzeki Wegolide waseShayina we-PPR kanye ne-Insert yaseShayina, Sizoqhubeka nokuzinikela ekuthuthukisweni kwemakethe kanye nomkhiqizo futhi sakhe isevisi ehlelekile kumakhasimende ethu ukuze sakhe ikusasa elichumayo. Kufanele usithinte namuhla ukuze uthole ukuthi singasebenzisana kanjani.
