PPR amapayipi

Uma kuqhathaniswa namapayipi ensimbi, amapayipi e-PPR anezinzuzo zokufakwa okulula, ukufakwa okungcono kwe-thermal, nokumelana nokugqwala. Iwumthombo wamanzi onempilo futhi ongayingeni imvelo futhi ingumkhiqizo wokuphakelwa kwamanzi ojwayelekile emakethe. Amapayipi e-PPR atholakala kakhulu ngemibala elandelayo, omhlophe, oMpunga, oluhlaza okotshani kanye nokhari, kungani kunomehluko udalwa ikakhulukazi ama-masterbatches anemibala ehlukene angezwe.

Ngokungeziwe ezicini zamapayipi epulasitiki ajwayelekile njengesisindo esilula, ukumelana nokugqwala, ukungancishisi, nempilo ende yenkonzo, amapayipi e-PP-R nawo anezici ezilandelayo eziyinhloko:

1 Akunabuthi futhi kuhlanzekile.
Ama-molecule wezinto ezingavuthiwe ze-PP-R ayizakhi ze-carbon ne-hydrogen kuphela, futhi azikho izinto eziyingozi nezinobuthi. Ihlanzekile futhi inokwethenjelwa. Ayisetshenziselwa kuphela amapayipi amanzi abandayo nashisayo, kodwa futhi nezinhlelo zamanzi okuphuza ahlanzekile.

2 Ukugcina ukushisa nokonga amandla.
I-conductivity eshisayo yepayipi ye-PP-R ingu-0.21w/mk, okuyi-1/200 kuphela yepayipi yensimbi.

3 Ukumelana nokushisa okungcono.
Iphoyinti lokuthambisa i-Vicat lepayipi le-PP-R ngu-131.5 ℃. Izinga lokushisa eliphakeme lokusebenza lingafinyelela ku-95 ℃, elingahlangabezana nezidingo zohlelo lwamanzi ashisayo endaweni yokwakhiwa kwamanzi kanye nekhodi yokukhipha amanzi.

4Impilo ende yesevisi.
Ngaphansi kwezimo zokushisa zokusebenza kwe-70 ℃ kanye nengcindezi yokusebenza (PN) ye-1.0MPa, impilo yesevisi yepayipi ye-PP-R ingafinyelela eminyakeni engaphezu kwengu-50 (inqobo nje uma impahla yepayipi kufanele ibe yi-S3.2 ne-S2.5 uchungechunge noma Okuningi); ngaphansi kwezinga lokushisa elivamile (20℃) Impilo yesevisi ingafinyelela eminyakeni engaphezu kweyi-100.

5 Ukufakwa okulula nokuxhumana okuthembekile.
I-PP-R inokusebenza okuhle kwe-welding. Amapayipi nokufakwa kungaxhunywa ngokuncibilika okushisayo kanye ne-electrofusion. Ukufakwa kulula futhi amalunga athembekile. Amandla okuhlangana makhulu kunamandla wepayipi ngokwayo.

6 Izinto zokwakha zingagaywa kabusha.
Imfucuza ye-PP-R iyahlanzwa, yephulwe, futhi igaywe kabusha ukuze isetshenziswe ekukhiqizeni amapayipi nokufakwa. Inani lezinto ezigaywe kabusha alidluli u-10% yenani eliphelele futhi alithinti ikhwalithi yomkhiqizo.
