Sikholelwa ukuthi ubambiswano lwesikhathi eside luwumphumela wekhwalithi ephezulu, isevisi eyengeziwe, ulwazi olucebile kanye nokuxhumana komuntu siqupr yethusi yokufaka isokhethi, “Ikhwalithi enhle nenani eliphansi” yizimiso zethu zebhizinisi. Uma unentshisekelo ezintweni zethu noma unemibuzo, kufanele uzizwe ukhululekile ukusithinta. Sithemba ukusungula ubudlelwano bokusebenzisana nawe esikhathini esizayo esiseduze.

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

Sikholelwa ukuthi ubambiswano lwesikhathi eside luwumphumela wekhwalithi ephezulu, isevisi eyengeziwe, isipiliyoni esicebile kanye nokuxhumana komuntu siqu Kwabathengisi Abathengisa Izitolo Ezihle 3/8′′ -4′′ Brass Forge PPR Fittings with Nickel Surface, Sibheke ngabomvu ukusungula ukubambisana. ubudlelwano nawe.
