Isicelo Of Plastic Amapayipi
Njengengxenye ebalulekile yezinto zokwakha zamakhemikhali, amapayipi epulasitiki amukelwa kabanzi ngabasebenzisi ngokusebenza kwawo okuphezulu, ukukhucululwa kwendle, ukuvikelwa kwemvelo, ukusetshenziswa okuphansi kanye nezinye izinzuzo, ikakhulukazi okuhlanganisa ipayipi lokudonsa amanzi le-UPVC, ipayipi lokuphakela amanzi le-UPVC, ipayipi eliyinhlanganisela yepulasitiki ye-aluminium, i-polyethylene ( PE) ipayipi lokuphakela amanzi, ipayipi lamanzi ashisayo le-polypropylene PPR.
Amapayipi epulasitiki ayizinto zokwakha zamakhemikhali ezihlanganiswe nobuchwepheshe obuphezulu, futhi izinto zokwakha zamakhemikhali ziwuhlobo lwesine olusafufusa lwezinto zokwakha ezintsha ngemva kwensimbi, izinkuni kanye nosimende.Amapayipi epulasitiki asetshenziswa kabanzi emikhakheni yokwakha amanzi kanye ne-drainage, ukuhlinzekwa kwamanzi emadolobheni kanye ne-drainage kanye namapayipi egesi ngenxa yezinzuzo zabo zokulahlekelwa kwamanzi amancane, ukonga amandla, ukonga izinto ezibonakalayo, ukuvikelwa kwemvelo, ukuqedwa okulula nokunye, futhi baye baba. amandla amakhulu enethiwekhi yamapayipi okwakhiwa kwamadolobha ekhulwini elisha leminyaka.
Uma kuqhathaniswa namapayipi ensimbi ensimbi, amapayipi ensimbi, amapayipi kasimende namanye amapayipi, amapayipi epulasitiki anenzuzo yokonga amandla nokonga impahla, ukuvikelwa kwemvelo, isisindo esincane namandla aphezulu, ukumelana nokugqwala, udonga lwangaphakathi olubushelelezi ngaphandle kokukala, ukwakhiwa okulula kanye ukugcinwa, impilo ende yesevisi nokunye.Asetshenziswa kakhulu ekwakhiweni, emikhakheni kamasipala, yezimboni nezolimo ezifana nokwakhiwa kwamanzi kanye ne-drainage, ukuhlinzekwa kwamanzi emadolobheni nasezindaweni zasemakhaya kanye ne-drainage, igesi yasemadolobheni, i-power and optical cable sheath, ukudluliswa koketshezi lwezimboni, ukuchelela kwezolimo nokunye.
Ipulasitiki ihlukile ezintweni zendabuko.Ijubane lokuthuthuka kwezobuchwepheshe liyashesha.Ukuvela okuqhubekayo kobuchwepheshe obusha, izinto ezintsha kanye nezinqubo ezintsha kwenza izinzuzo zamapayipi epulasitiki zivelele nakakhulu uma ziqhathaniswa nezinto zendabuko.Uma kuqhathaniswa nepayipi lensimbi lendabuko kanye nepayipi likasimende, ipayipi lepulasitiki linesisindo esincane, ngokuvamile esiyi-1/6-1/10 kuphela yepayipi lensimbi.Inokumelana nokugqwala okungcono, ukumelana nomthelela namandla aqinile.Ingaphakathi lepayipi lepulasitiki libushelelezi kakhulu kunepayipi lensimbi ekhonjiwe, eline-coefficient encane yokungqubuzana nokumelana noketshezi.Inganciphisa ukusetshenziswa kwamandla okudluliswa kwamanzi ngaphezu kuka-5%.Inokongiwa kahle kwamandla okuphelele, kanti ukusetshenziswa kwamandla okukhiqiza kwehliswa ngama-75%.Kulula ukuthutha, kulula ukuyifaka, futhi impilo yayo yesevisi ifinyelela eminyakeni engama-30-50.Amapayipi e-polyethylene athuthuke ngokushesha emhlabeni, futhi amazwe athuthukile anenzuzo ephelele ekusetshenzisweni kwamapayipi e-polyethylene emkhakheni wokuhlinzekwa kwamanzi negesi.Amapayipi e-polyethylene awasetshenziswa kabanzi kuphela esikhundleni samapayipi ensimbi yendabuko kanye namapayipi ensimbi, kodwa futhi ukufaka esikhundleni samapayipi e-PVC.Isizathu sitholakala emisha yezobuchwepheshe yamapayipi e-polyethylene.Ngakolunye uhlangothi, ukwaziswa kuye kwathuthuka kakhulu.Ngokuthuthukiswa kwenqubo yokukhiqiza i-polyethylene polymerization, amandla wepayipi le-polyethylene impahla ekhethekile cishe aphindwe kabili.Ngakolunye uhlangothi, kunentuthuko entsha kubuchwepheshe bokufaka isicelo, njengobuchwepheshe bokubeka amapayipi e-polyethylene ngendlela yokumba eqondisayo ngaphandle kokumba imisele yamapayipi, okunikeza ukudlala okugcwele ezinzuzweni zamapayipi e-polyethylene, ukuze amapayipi endabuko angabikho ukuncintisana ngezikhathi ezithile. ilungele le ndlela.Kukhona futhi izinto eziningi ezintsha kanye nobuchwepheshe okufundwayo, noma okuhloliwe futhi kwahlolwa.Kuqinisekile ukuthi inqubekelaphambili yezobuchwepheshe yamapayipi epulasitiki eminyakeni eyi-10 ezayo izokhuthaza ukuthuthukiswa okusheshayo kanye nokusetshenziswa okubanzi kwamapayipi epulasitiki.
