Qiniseka ukuthi usho okuthathu, kufanele kube: I-PPR, i-PVC, i-PE
1. Amapayipi epulasitiki asetshenziswa kakhulu yilawa: I-PPR (i-polypropylene), i-PVC (i-polyvinyl chloride), i-PB (i-polybutene), i-PE-RT (i-polyethylene engashisi), i-PE (polyethylene) \HDPE (i-polyethylene eqinisiwe ephezulu) i-ethylene), njll.
Okwesibili, ubukhulu bamapayipi epulasitiki ngokuvamile buvezwa ngobubanzi bangaphandle.Okufana ne-PPR tube: De63
3. Impilo yesevisi yeI-MF BALL VALVE X9011kunqunywa ngokusho kwe-GB/T18252-2000 "Uhlelo lwamapayipi ePlastiki - Ukunqunywa kwamandla wesikhathi eside we-hydrostatic wamapayipi we-thermoplastic ngokukhipha".Lena indlela yokwengeza ngokwezibalo nokubikezela izici zamandla zesikhathi eside zezinto ezisetshenziswayo ze-thermoplastic noma ama-athikili kusukela kumiphumela yokuhlolwa kwamandla e-hydrostatic wamapayipi.*Iningi labangenhla lisebenzisa le ndlela ukubala, ngaphansi kwesimo sokushisa esingu-20 ℃, ipayipi lepulasitiki ngokuvamile liphila iminyaka engu-50.
Okwesine, umshini wokubumba wamapayipi epulasitiki umshini wokubumba umjovo, obunjwa ube amapayipi ngomshini wokubumba umjovo.
5. Ngokuvamile kunezindlela ezimbili zokuxhuma amapayipi epulasitiki: ukuncibilika okushisayo kanye neglue.
6. Izindinganiso zamapayipi epulasitiki ikakhulukazi zihlanganisa:
1. I-PPR (i-polypropylene): GB/T18742.1, GB/T18742.2, GB/T18742.3
2. I-PVC (i-polyvinyl chloride): GB/T10002.1-2006, GB/T10002.2-2003
3. I-PE (i-polyethylene): GB15558, GB/T13663
4. I-HDPE (I-Polyethylene Ethuthukisiwe Yokuminyana Okuphezulu): GB/T19472.2-2004
Amapayipi epulasitiki ikakhulukazi ahlanganisa i-PPR (i-polypropylene), i-PVC (i-polyvinyl chloride), i-PB (i-polybutene), i-PE-RT (i-polyethylene engashisi), i-PE (i-polyethylene), i-HDPE (i-polyethylene ephezulu ethuthukisiwe), njll. Izinto ezisetshenziswayo ziyizi i-polypropylene (PP), i-polyvinyl chloride (PVC), i-polyethylene (PE) namanye ama-polymers.
Ipayipi lepulasitiki yigama elijwayelekile lamapayipi enziwe ngezinto zepulasitiki.Amapayipi epulasitiki anezici zesisindo sokukhanya, ukukhucululwa kwendle nokuphepha, ukumelana nokugeleza kwamanzi amancane, ukonga amandla, ukonga insimbi, ukuthuthukiswa kwendawo ehlala kuyo, impilo ende yenkonzo, ukuphepha kanye nokuba lula, njll., futhi athandwa umphakathi wobunjiniyela bamapayipi.Eminyakeni eyi-10 edlule, eqhutshwa ukuthuthukiswa komnotho wezwe lami, amapayipi epulasitiki ezwe lami athole intuthuko esheshayo ngaphansi kwesizinda sokuthuthukiswa okukhulu kwezinto zokwakha amakhemikhali.Ngo-2010, umkhiqizo kazwelonke wamapayipi epulasitiki wedlula amathani ayizigidi ezingu-8, lapho i-Guangdong, iZhejiang ne-Shandong ibalelwa ku-42% womkhiqizo.Amapayipi epulasitiki anezinzuzo eziningi ngaphezu kwamapayipi ensimbi endabuko namapayipi kakhonkolo emikhakheni eminingi, ngakho asetshenziswe kabanzi ezindaweni eziningi.
