Amapayipi e-Polyvinyl chloride (PVC) asephenduke isisekelo sengqalasizinda yesimanje, ukwakhiwa, nezinhlelo zokufaka amapayipi amanzi, aziswa ngokuqina kwawo, ukufinyeleleka kwawo, kanye nokuguquguquka kwawo. Izinga lala mapayipi linqunywa kakhulu uhlobo lwe-PVC resin esetshenziswa ekukhiqizeni kwawo.
Kulo mhlahlandlela obanzi, sizongena emhlabeni wezinsalela ze-PVC, sihlole izici ezibalulekile okufanele zicatshangelwe lapho kukhethwa inhlaka engcono kakhulu yokukhiqizwa kwamapayipi ekhwalithi ephezulu.
Izinto Ezithonya Ukukhetha Kweresin ye-PVC
Ukukhetha i-PVC resin efanele yokukhiqizwa kwamapayipi kuhilela ukucutshungulwa ngokucophelela kwezinto ezimbalwa, ezihlanganisa:
Isisindo samangqamuzana: Isisindo sengqamuzana se-PVC resin sidlala indima ebalulekile ekunqumeni amandla ombhobho wepayipi, ukuqina, kanye nokusebenza kukonke. Ama-resin esisindo samangqamuzana aphezulu ngokuvamile aholela kumapayipi anokumelana nomthelela okuthuthukisiwe kanye nokuqina.
I-Melt Flow Index (MFI): I-MFI ibonisa ukugeleza kwe-resin ngesikhathi senqubo yokukhipha. I-MFI efanelekile iqinisekisa ukukhishwa okubushelelezi, ubukhulu bepayipi obufanayo, nokuncipha kokulimala kokucubungula.
I-Vicat Softening Temperature (Vicat B): I-Vicat B imele izinga lokushisa lapho inhlaka iqala ukuthamba ngaphansi komthwalo. Inani eliphakeme le-Vicat B libonisa ukumelana nokushisa okungcono kanye nokuzinza kwe-dimensional kwamapayipi.
Izithasiselo: Ama-resin e-PVC avame ukwakhiwa ngezithasiselo ukuze kuthuthukiswe izakhiwo zawo nezici zokucubungula. Izithasiselo ezijwayelekile zifaka ama-stabilizer, ama-filler, izinto zokuthambisa, neziguquli zomthelela.
Izinhlobo ze-PVC Resin for Pipe Production
Ngokusekelwe ezicini ezishiwo ngenhla, ama-PVC resins okukhiqizwa kwamapayipi angahlukaniswa kabanzi ngezinhlobo ezimbili eziyinhloko:
I-Suspension PVC (S-PVC): Ama-resin e-S-PVC akhiqizwa kusetshenziswa inqubo ye-polymerization yokumiswa, okuholela ezinhlayiyeni eziyindilinga ezinokusabalalisa okubanzi kwesisindo samangqamuzana. Banikeza ibhalansi enhle yamandla omthelela, ukuqina, nezici zokucubungula.
I-Emulsion PVC (E-PVC): Ama-resin e-E-PVC akhiqizwa ngenqubo ye-emulsion polymerization, enikeza izinhlayiya ezingcono kakhulu ezinokusabalalisa kwesisindo samangqamuzana amancane. Ngokuvamile abonisa amandla omthelela aphezulu kanye nokuqina okuphansi uma kuqhathaniswa nezinsalela ze-S-PVC.
Ukukhetha i-resin engcono kakhulu yezidingo zakho
Ukukhethwa kwe-resin ye-PVC efanelekile kakhulu yokukhiqiza ipayipi kuncike ekusetshenzisweni okuqondile kanye nezakhiwo zamapayipi ezifunwayo. Isibonelo, amapayipi ahloselwe ukusetshenziswa kwengcindezi adinga ama-resin anesisindo samangqamuzana aphezulu kanye namanani e-Vicat B ukuze kuqinisekiswe amandla anele nokumelana nokushisa.
Ngokuphambene, amapayipi ezicelo ezingezona ingcindezi, njengama-drainage noma ukuchelela, angase abeke phambili amandla omthelela kanye nokucutshungulwa kalula, okwenza ama-E-PVC ama-resins abe yisinqumo esifanele.
Isiphetho
Ukukhethwa kwe-PVC resin kuyisici esibalulekile sokukhiqiza amapayipi e-PVC aphezulu. Ngokuqonda izici ezibalulekile ezithonya ukukhethwa kwe-resin kanye nezakhiwo zezinhlobo ezahlukene ze-resin, abakhiqizi bamapayipi bangenza izinqumo ezinolwazi ezithuthukisa ukusebenza kwamapayipi futhi bahlangabezane nezidingo zezinhlelo zokusebenza ezihlukahlukene.
Khumbula ukuthi ukubonisana nabahlinzeki bezinhlaka ze-PVC abanolwazi futhi ukufuna isiqondiso sobuchwepheshe kungaba usizo ekukhetheni inhlaka efanelekile yezidingo zakho ezithile zokukhiqiza amapayipi.
