Ipulasitiki esivame ukuyisebenzisa akuyona into ehlanzekile, yakhiwe ngezinto eziningi.Phakathi kwazo, ama-polymers ama-molecular aphezulu yizingxenye eziyinhloko zamapulasitiki.Ngaphezu kwalokho, ukuze kuthuthukiswe ukusebenza kwamapulasitiki, izinto ezihlukahlukene ezisizayo, ezifana nama-fillers, ama-plasticizers, ama-lubricant, ama-stabilizers, ama-colorants, njll, kufanele afakwe ku-polymer.Ipulasitiki yokusebenza kahle.
I-Plastic synthetic resin: I-polymer yamangqamuzana ephezulu, ebizwa nangokuthi i-synthetic resin, iyisakhi esibaluleke kakhulu sepulasitiki, futhi okuqukethwe kwayo kupulasitiki ngokuvamile ku-40% kuya ku-100%.Ngenxa yokuqukethwe okukhulu kanye nezakhiwo zama-resin avame ukunquma izakhiwo zepulasitiki, abantu bavame ukubheka ama-resin njengefana nepulasitiki.
Izigcwalisi zesikhwama sePlastiki: ama-fillers abizwa nangokuthi ama-fillers, angathuthukisa amandla nokumelana nokushisa kwamapulasitiki futhi anciphise izindleko.Isibonelo, ukwengeza i-wood powder ku-phenolic resin kunganciphisa kakhulu izindleko, okwenza ipulasitiki ye-phenolic ibe yinye yepulasitiki eshibhile, futhi ngesikhathi esifanayo, ingathuthukisa kakhulu amandla omshini.Izigcwalisi zingahlukaniswa zibe izigcwalisi eziphilayo kanye nezigcwalisi ezingaphili, ezokuqala ezinjengofulawa wokhuni, ama-rags, amaphepha nemicu yendwangu ehlukahlukene, njll., lena yokugcina efana ne-glass fiber, umhlaba we-diatomaceous, i-asbestos, i-carbon black nokunye.
Ama-plasticizers ezikhwama zepulasitiki: Ama-plasticizers angakhuphula ipulasitiki nokuthambile kwamapulasitiki, anciphise ukonakala, futhi enze amapulasitiki acutshungulwe futhi akheke kalula.Ama-Plasticizers ngokuvamile ayinhlanganisela ye-resin-miscible, ayinabuthi, ayinaphunga, izinhlanganisela eziphilayo ezibilayo eziqinile ekukhanyeni nasekushiseni.Okuvame ukusetshenziswa kakhulu ama-phthalates.
I-stabilizer yesikhwama sepulasitiki: Ukuze uvimbele i-resin yokwenziwa ukuthi ingaboli futhi ibhujiswe ukukhanya nokushisa ngesikhathi sokucutshungulwa nokusetshenziswa, futhi andise impilo yesevisi, kufanele kwengezwe isizinzisi epulasitikini.Okuvame ukusetshenziswa yi-stearate, epoxy resin nokunye.
Imibala yezikhwama zepulasitiki: Imibala inganikeza amapulasitiki izinhlobonhlobo zemibala ekhanyayo, emihle.Odayi be-organic kanye nezingulube ze-inorganic zivame ukusetshenziswa njengama-colorants.
I-lubricant yesikhwama sepulasitiki: Umsebenzi we-lubricant ukuvimbela ipulasitiki ukuthi inganamatheli ekubunjweni kwensimbi ngesikhathi sokubunjwa, futhi ngesikhathi esifanayo yenza ubuso bepulasitiki bushelelezi futhi bube buhle.Izithambisi ezisetshenziswa kakhulu yi-stearic acid kanye nosawoti wayo we-calcium ne-magnesium.
Ngaphezu kwezithasiselo ezingenhla, izinqamuli zomlilo, ama-agent akhihliza amagwebu, ama-antistatic agents, njll. nazo zingangezwa kumapulasitiki ukuze kuhlangatshezwane nezidingo ezahlukene zohlelo.
