Ngokusekelwa kwamakhasimende amaningi abambisene isikhathi eside, izixazululo zethu zamukelwa emhlabeni wonke.

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

Imishini eqhutshwa kahle, ithimba lokuthengisa elingochwepheshe, kanye nezinsizakalo ezingcono ngemuva kokuthengisa; Singumndeni omkhulu ohlangene, wonke umuntu unamathela enanini lenkampani "ubunye, ukuzinikela, ukubekezelelana" kwekhwalithi ephezulu Umkhiqizi we-Ifan imibala eluhlaza 45 indololwane 20mm-110mm zonke izinhlobo zokufakwa kwe-ppr amagama okusheshayo kokufakwa kwe-ppr, Sidlala indima ehamba phambili ekuhlinzekeni amakhasimende ngezinto ezisezingeni eliphezulu umhlinzeki omuhle kakhulu kanye namanani ancintisanayo.
Ikhwalithi enhle kakhulu, Ngemva kweminyaka eminingi yokuthuthukiswa, manje sesisungule ikhono eliqinile ekuthuthukisweni komkhiqizo omusha kanye nohlelo lokulawula ikhwalithi oluqinile ukuqinisekisa ikhwalithi enhle kakhulu kanye nensizakalo. Ngokusekelwa kwamakhasimende amaningi abambisene isikhathi eside, izixazululo zethu zamukelwa emhlabeni wonke.
