Ipayipi esobala le-PVCyenziwe nge-PVC resin ngokungeza inani elikhulu le-plasticizer, inani elithile le-stabilizer nezinye izithasiselo, ngokusebenzisa ukubunjwa kwe-extrusion.Inezici zokukhanya nokubushelelezi, isisindo esilula, ukubukeka okuhle, ukuthambile kanye nombala omuhle, njll. Isetshenziswa kabanzi ekwakhiweni, embonini yamakhemikhali kanye nomndeni, isetshenziselwa ukumnika amanzi, ukudlulisa i-corrosive medium, futhi ibuye isetshenziswe njenge-wire casing kanye ungqimba lwe-wire insulation.

Ifomula ye-hose ebonakalayo ye-PVC ikakhulukazi ihlanganisa inhlaka ye-PVC, i-heat stabilizer, i-lubricant, i-plasticizer kanye ne-colorant.Idizayini yefomula kufanele ihlangabezane nezidingo zokungafihli lutho, ubulukhuni obumaphakathi namandla aphezulu.Ukuze kuthuthukiswe obala, ekukhetheni izesekeli zokucubungula, ngangokunokwenzeka ukukhetha inkomba ye-refractive kanye ne-PVC resin refractive index (1) izithasiselo ezifanayo noma ezifanayo.Ngenxa yokuthi inkomba ye-refractive efanayo noma efanayo yempahla eluhlaza ecutshungulwe yaba yingxube efanayo, inkomba ye-refractive kanye nenkomba ye-refractive yempahla eluhlaza iyafana.Ngale ndlela, isenzakalo esihlakazekayo esibheke ekukhanyeni kwesigameko ngeke sande, ngakho-ke ukuthuthumela komkhiqizo ngeke kwande, futhi ukucaca komkhiqizo ngeke kuthinteke kakhulu.

I-PVC resin: ngenxa yenani elikhulu le-plasticizer efomini, i-PVC resin iyadingeka ukuze imunce kahle amafutha, futhi i-resin evulekile kufanele ikhethwe.Ngesikhathi esifanayo, ubumhlophe obuphezulu nokuzinza okuhle kokushisa kwe-resin kuyadingeka.Iqoqo elinenani eliphansi lokungcola kanye nenani lezinhlanzi.Esimweni sokuhlangabezana nezidingo zezakhiwo zemishini, ukukhiqizwa kwepayipi elibonisa ngale ye-PVC kufanele kusetshenziswe ngangokunokwenzeka nge-resin ephansi yesisindo samangqamuzana.Ngenxa yokuthi i-plasticizer evame ukusetshenziswa i-DOP ne-DBP ngokuvamile iqukethe ingxenye enesisindo samangqamuzana aphansi, lapho izinga lokushisa lokucubungula lingaphezu kuka-105 ℃, ngokuvamile lingashintshashintsha futhi lenze ibhamuza, izinga lokushisa lingalawula ohlangothini oluphansi kuphela.Kulokhu, izinga le-plasticization kanye nokuncibilika kwe-resin enesisindo esilinganiselwe samangqamuzana liphakeme kunele-resin enesisindo esikhulu samangqamuzana, esiza ekuthuthukiseni ukubonakala kwemikhiqizo.Ngaphezu kwalokho, ama-resin aphansi esisindo samangqamuzana nawo alula ukucubungula.I-General PVC-SG3, SG4, SG5 resin ingakhethwa ngokuya ngezidingo zomkhiqizo.

I-Plasticizer: ikakhulukazi cabangela umphumela wayo we-plasticizing, ukumelana nokubanda, ukuqina kanye nomthelela we-PVC obala.I-DOP iyi-plasticizer enokusebenza okuhle okubanzi, futhi inkomba yayo ye-refractive ingu-1.484, eseduze ne-PVC (1.52 ~ 1.55).Ngokuvamile isetshenziswa njenge-plasticizer eyinhloko ye-PVC esobala hose.Inkomba ye-refractive ye-DBP ingu-1.492, nayo eseduze naleyo ye-PVC resin.Ngeke kuthinte obala kakhulu, kodwa ukukhula kahle kwayo kuphansi, futhi kuyaguquguquka, futhi ngokuvamile isetshenziswa njenge-plasticizer eyi-DOP.Ukuze uthuthukise ukumelana nokubanda, i-DOS ingangezwa njenge-plasticizer eyengeziwe.Umthamo we-plasticizer ungama-40 ~ 55 ngokujwayelekile.

I-stabilizer yokushisa: ngaphezu kwezidingo zokumelana nokushisa, ukumelana nesimo sezulu kanye nokucubungula okulula nezinye izakhiwo eziyisisekelo, kufanele futhi kugxile ekukhanyeni kwayo.I-Organotin stabilizer iyisinzinzisi sokushisa esifanele kunazo zonke nesivame ukusetshenziswa kakhulu semikhiqizo esobala ye-PVC, kodwa intengo iphezulu.Iziqinisi zensipho yensimbi, ezifana ne-calcium stearate, i-barium stearate, i-zinc stearate, njll., zivame ukusetshenziswa njengezinzisi zokushisa zamashubhu ANGAVIKILEYO we-PV C. Imikhiqizo eyinhlanganisela Ca/ Zn, Ba/ Zn, Ba/ Ca kanye ne-Ba/ Ca/ Zn zinhle kakhulu.Ukuze kuncishiswe inani le-organotin, i-calcium stearate (insipho ye-calcium) kanye ne-zinc stearate (insipho ye-zinc) enokukhanya okuhle kanye nokugcotshwa kwasetshenziswa njengeziqinisi ezisizayo.
