Izinto ezingavuthiwe zepulasitiki yi-resin yokwenziwa, ekhishwa futhi ihlanganiswe ku-petroleum, igesi yemvelo noma ukuqhekeka kwamalahle.Uwoyela, igesi yemvelo, njll. kuchithwa kube yizinhlanganisela zamangqamuzana aphansi (njenge-ethylene, i-propylene, i-styrene, i-ethylene, i-vinyl alcohol, njll.), kanye ne-low-molecular compounds yenziwa i-polymerized ibe i-high-molecular organic compounds ngaphansi kwezimo ezithile. , bese kuba ama-plasticizers, ama-Lubricant, ama-filler, njll., angenziwa abe yizinto ezihlukahlukene zokusetshenziswa kwepulasitiki.Ngokuvamile, ama-resin acutshungulwa abe yi-granules ukuze kube lula ukusetshenziswa.Ngokuvamile zibunjwa zibe amadivaysi anomumo othize ngaphansi kwezimo zokushisa nengcindezi.
Izici ezingokomzimba zamapulasitiki.Kunezinhlobo eziningi zezakhiwo ezibonakalayo zamapulasitiki, okulandelayo yizinto ezimbalwa kuphela ezidinga ukuqondwa ngokufunda ubuchwepheshe be-toning:
1. Ukuminyana okuhlobene: Ukuminyana okuhlobene isilinganiso sesisindo sesampula nesisindo sevolumu efanayo yamanzi ezingeni lokushisa elithile, futhi kuyindlela ebalulekile yokuhlonza izinto zokusetshenziswa.
2. Izinga lokumuncwa kwamanzi: Izinto zokusetshenziswa zepulasitiki zenziwa isampula losayizi othile, ocwiliswa emanzini acwecwe ngezinga lokushisa elingu-(25±2) ℃, kanye nesilinganiso senani lamanzi amuncwa isampula kokuluhlaza. ngemva kwamahora angu-24.Ubukhulu bokumuncwa kwamanzi bunquma ukuthi impahla eluhlaza yepulasitiki idinga ukubhakwa kanye nobude besikhathi sokubhaka.
3. Izinga lokushisa lokubumba: Izinga lokushisa lokubumba libhekisela ekushiseni okuncibilika kwe-resin eluhlaza
4. Izinga lokushisa lokubola: Izinga lokushisa lokubola libhekisela ekushiseni lapho iketango le-macromolecular lepulasitiki liphuka lapho lishisa, futhi lingenye yezinkomba zokukhomba ukumelana nokushisa kwepulasitiki.Lapho izinga lokushisa elincibilikayo lidlula izinga lokushisa lokubola, izinto eziningi zokusetshenziswa zizophenduka zibe phuzi, zize zishise zibe mnyama, futhi amandla omkhiqizo azoncipha kakhulu.
