Amapayipi e-polypropylene (amapayipi e-PP) asetshenziswa kakhulu ekwakheni amanzi kanye ne-drainage, ukuthutha uketshezi lwezimboni, nezinye izinkambu ngenxa yokumelana nokugqwala okuhle kakhulu, amandla angasindi namandla aphezulu, nokufakwa kalula. Ngokusekelwe eminyakeni yokuzijwayeza yobunjiniyela, umbhali ufinyeze okuhlangenwe nakho okubalulekile okulandelayo:
Ukukhetha Okuqinile Okubalulekile kubalulekile. Amapayipi e-polypropylene ahlukaniswe abe izigaba ezintathu: i-homopolymer (PP-H), i-copolymer (PP-}), ne-copolymer engahleliwe (PP-}). Phakathi kwazo, i-PP-R inketho ekhethwayo yamasistimu amanzi ashisayo nabandayo asekhaya ngenxa yokuxhumeka kwawo okuthembekile kokuhlanganiswa kokushisa kanye-nokumelana nezinga lokushisa lesikhathi eside elingaphezu kuka-70℃. Lapho uthenga, imvume yomkhiqizi yokuhlanzeka kanye nesitifiketi sokulinganisa ingcindezi kufanele kuqinisekiswe ukuze kugwenywe ukusebenzisa amapayipi aphansi enziwe ngezinto ezigaywe kabusha.
Inqubo yokufaka ibalulekile. Ngesikhathi sokuxhumeka kokuhlanganiswa kokushisa, izinga lokushisa lokushisa kwepayipi kanye nokuhlangana kufanele kulawulwe ngokunembile ku-260±10 degree, futhi ukujula kanye nesikhathi sokufaka kufanele kulandelwe ngokuqinile ngokuvumelana nebhukwana lobuchwepheshe lomkhiqizi. Ukwehluleka okuvamile kuvame ukuvela ekushiseni ngokweqile okuholela ekushiseni kwepayipi, noma ukufaka okunganele okubangela ukuvuza. Kunconywa ukusebenzisa umshini wokuhlanganisa ukushisa onomsebenzi wokuboniswa kwedijithali kanye nokwenza ukuhlolwa kwamakhono okusebenzayo kubasebenzi bokwakha.
Ukugcinwa Kwesistimu Kugcizelela Ukuvimbela. Nakuba amapayipi e-PP amelana kakhulu nokugqwala kwamakhemikhali, ukuthuthwa kwesikhathi eside kwezisombululo ze-ion ze-concentration chloride ion{1}kusengadala ukuqhekeka kwengcindezi. Kutuswa ukuthi kufakwe izinto ezivikela umfutho ezisetshenziswa ezimbonini, kanti ezinhlelweni zokuhlala, izinsimbi zamapayipi kufanele zihlolwe njalo ukuze kuvinjelwe ukuxega ngenxa yokudlidliza kwamanzi. Ukunakwa okukhethekile kuyadingeka ngesikhathi sokwakhiwa kwasebusika; kufanele kuthathwe izinyathelo zokuhlanganisa lapho izinga lokushisa elizungezile lingaphansi kwama-degree angu-5 ukuze kuvinjwe ukuqhuma kwamapayipi.
Ngokwempendulo yephrojekthi, ukukhethwa kwempahla efanele kanye nokwakhiwa ngokucophelela kunganweba isikhathi sokuphila sezinhlelo zamapayipi e-PP sibe ngaphezu kweminyaka engama-50. Ngokuthuthuka kobuchwepheshe bezinto ezibonakalayo, imikhiqizo eshintshiwe njengamapayipi e-fiberglass PP aqinisiwe izoqhubeka nokwandisa izimo zayo zohlelo esikhathini esizayo, kodwa okubalulekile kusalokhu kubambelela ezintweni ezibonakalayo nokulawula yonke imininingwane yobuchwepheshe.
