Incazelo ephezulu ye-ISO Izitifiketi Zethusi Zokufaka Kwabesilisa Kwe-PPR Ipayipi Lethusi Lombala Intengo Ephansi
Ukwaneliseka kwekhasimende yikona esikuhlosile okuyinhloko. Siphakamisa izinga elingaguquki lobungcweti, ikhwalithi, ukwethembeka kanye nesevisi yencazelo Ephezulu Izitifiketi Ze-ISO Ze-Brass Male Insert ye-PPR Ipayipi Lethusi Lombala Intengo Ephansi Kakhulu, Sithola ikhwalithi ephezulu njengesisekelo semiphumela yethu. Ngakho-ke, sigxila ekwenziweni kwezimpahla zekhwalithi ephezulu kakhulu. Kudalwe isistimu yokuphatha ikhwalithi eqinile ukuze kuqinisekiswe izinga lokuthengiswayo.
Ukwaneliseka kwekhasimende yikona esikuhlosile okuyinhloko. Siphakamisa izinga elingaguquki lobuchwepheshe, ikhwalithi, ukwethembeka kanye nenkonzoppr zethusi faka, Sihlale siphikelela ekuthuthukisweni kwezixazululo, sasebenzisa izimali ezinhle nabasebenzi ekuthuthukiseni ubuchwepheshe, futhi senza lula ukuthuthukiswa kokukhiqiza, sihlangabezane nezidingo zamathemba avela kuwo wonke amazwe nezifunda.
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.
ukufakwa
Ukwaneliseka kwekhasimende yikona esikuhlosile okuyinhloko. Siphakamisa izinga elingaguquki lobungcweti, ikhwalithi, ukwethembeka kanye nesevisi yencazelo Ephezulu Izitifiketi Ze-ISO Ze-Brass Male Insert ye-PPR Ipayipi Lethusi Lombala Intengo Ephansi Kakhulu, Sithola ikhwalithi ephezulu njengesisekelo semiphumela yethu. Ngakho-ke, sigxila ekwenziweni kwezimpahla zekhwalithi ephezulu kakhulu. Kudalwe isistimu yokuphatha ikhwalithi eqinile ukuze kuqinisekiswe izinga lokuthengiswayo.
Incazelo ephezulu ye-PPR kanye ne-Isert, Sihlale siphikelela ekuthuthukisweni kwezixazululo, sasebenzisa izimali ezinhle nabasebenzi ekuthuthukiseni ubuchwepheshe, futhi senza lula ukuthuthukiswa kokukhiqiza, sihlangabezane nezidingo zamathemba avela kuwo wonke amazwe nezifunda.
