Okwamanje, sikhona izilinye zesixhenxe sezinkampani zasePVC-UH, nezinhlobo zokuproducwa ziyakhuluma kwi-DN50–DN800 futhi inqanawa yokuqala yezinkampani yingakhiwa ku-26,640 tons ngonyaka. Lokhu kubhekwa phakathi kwemizimba yezinsiza zomoya wasezinsizweni, imizimba yezinsiza zomoya wasezinsizweni, imizimba yezinsiza zomoya wasezinsizweni, imizimba yezinsiza zomoya wasezinsizweni, nokho kunezinkinga eziningi zokuphatha izinsiza zomoya wasezinsizweni.
Izinhlanga ze-polyvinyl chloride eziphakeme (UPVC) ziyachazwa ngokusebenzisa i-polyvinyl chloride resin njengomthwalo wokwenza, ngekubheka kwezinkampani ezidingekayo ukwenza izinhlanga ezifanele kumfanekiso, futhi akukho ukusetshenziswa kwezinkampani zokuvutha kulesi simiso.
Emva kokuthuthukiswa nokuvuselela leliqondo lesilinda, izinkulungwane zokusebenza kwezinto zokuphatha kwakhiwe kahle kusukela emaqhingweni asePVC-U nePVC-M, futhi indlela yokuxhuma silinda kwalungisele. Ngaphezu kwalokho, kubhekwa ukuthi kuzokhishwa amaphetha njengezinye zezikhumba, izikhumba zesi-3, izikhumba zesi-4, izifalansi, izikhumba zesi-Y, izikhumba zesi-T, nezinhlobo zokugcina.
Izinkulungwane zezinto zokuphatha zePVC-UH ziyizilinda zokususa amanzi neziphetha ezihlakile ngokwezilinda zezilonda (PVC-UH) zokwenzwa ngokulinganisa nesistimu yokuqinisekisa ubukhulu yeISO9002.
Isimo sokusebenzisa izinto: SZDB/Z 239-2017 (ngokuchazwa kukaGB/T20221), nangamakhulu amaningi okusebenzisa izindlela nokubhalwa kwezindawo zokubanga. Kulinganisa nezilinda zemetalu, kunezinkulungwane ezingaphambili eziningi, kufuneka kubhekwe ukuxhuma okuhlanganisa, umsindo omncane, ubukhulu obukhulu bokuxhuma, ukungafani kwezilinda zokuhamba kwezilonda, ubukhulu obukhulu bokuhlambulula izilonda, ukufanelana kwezilonda, ukuthengiswa okuncane, nokusebenza kahle kwezilinda.
★Isiphumo esihle kakhulu se-PVC-UH - Ukubambisana Okuphelele★
Isithuthi sokubambisana esisemthethweni sasezinkampani zokugcina ezinamandla ematilisi
Kungafani nesizinda esizinye sezinkampani ezenza iziringi zokugcina ngemuva kokufaka, izinkampani ze-PVC-UH zisebenzisa isithuthi sokubambisana esisemthethweni sasezinkampani zokugcina ezinamandla ematilisi, okungakwazi ukuzimela izinkinga ezifanele njenge-‘misalignment’, ukuguqula, nokuhamba kweringi lokugcina ngemuva kokufaka.
Kungakwazi ukumelisa umkhosi wokubambisana wonke phakathi kwezinkinga zokuchitha, ukudlula kwezinkinga zokudlula, ukuguqula kwesandla, nokuguqula nokukhula nokushisa, kuyabeka isiphumo esikhulu sokuchitha emaphakathini amahle.
Izinkinga ezingcono zesi-PVC-UH
Ukusebenza okuhle kwezinhlangano zokuphatha izibonelo
Akunayo imithi yezibonelo futhi ayikho ukuchitha kwesibili, izinkampani ze-PVC-UH ezenza ukulwa kuyizibonelo nezinhlangano. Ngemuva kokusebenzisa, akuzange kwenza ukuchitha, akuzange kusiza ukuthuthuka kwezibonelo noma izinhlangano ezingeni elinye, futhi akuzange kwenza ukuchitha kwesibili kwezibonelo.
Ukuhamba kwezibonelo okuhle kakhulu
Izihluzi ze-PVC-UH zinomphakathi wokugcina omhlophe futhi zinamandla okugcina okungafani, noma kubhekwa kumkhawulo wokugcina wawo wakhiwa ngokulinganisa 0.008-0.009. Iqiniso lokugcina kwazo liyinkulu ngama-25% kulokugcina kwezihluzi zezincu futhi liyinkulu ngama-50% kulokugcina kwezihluzi zebhetha.
Ubude bokuphila
Isikhathi sokusebenza eside: Izihluzi zezinhlobo zokuzimisa zinomkhathi wokusebenza we-20 ku-30 iminyaka, kodwa izihluzi ze-PVC-UH zinomkhathi wokusebenza awangafani na-50 iminyaka.
Ukuthuthwa Kungenjalo
Zingaphansi kakhulu futhi zibalulekile ukuthuthukisa, izihluzi ze-PVC-UH zinomkhawulo ongafani na-1/5 wokwesithili noma kwezincu, futhi 1/3 yebhetha. Umkhawulo wazo uyisilinganiso se-1/4 wokwesithili esifanayo noma kwezincu zokuphatha, futhi 1/10 yebhetha. Ngakho-ke, zibalulekile ukuthuthukisa futhi zingabeka umsindo wokuthuthukisa uphansi ngama-1/3 ku-1/2.
Amathuba amuhle okusebenza
Ukuchitha kwezindawo zokuchitha kwi-23% ayikwazi ukungafani na-45 MPa, noma kubhekwa kumthwalo wokuchitha, futhi ayizokhulula lapho kuchithwa kusilinganiso se-1/2 yomkhawulo wokuphatha.
Kukholwa Ngokomlando
Izihluzi ze-PVC-UH ziyizinga, zikhulula ukubambisana, futhi zinezinhlobo zezindawo ezizimele. Ngakho-ke, zikhulula ukufaka, okwenza ukuthi iziphumo zabo zibhekene ngokuphelele nezihluzi ezingaphansi kwezinye izihluzi ezinamathuba amaningi.
Ukholwa okuncane
Ukholwa wezihluzi ze-PVC-UH kuyingu-30% kuphela kwezihluzi zemithi yomthwalo noma zebhukhali.
Okwamanje, iseri ye-PVC iyashiyela i-PVC-O, i-PVC-M, i-PVC-U, futhi i-PVC-UH eyadluliselwe kabusha, ibonisa iseri esifanayo sezinto zokusebenza nezinhlobo zokusebenza, futhi ibonisa izinkinga eziningi. Lokhu yisihluzi esingeni esisheshayo esithile kuthi, emva kwezihluzi ze-SRTP, izihluzi zepolyethylene (PE), futhi izihluzi zokuhlanganisa izinkampani zemithi neplastiki.
