Izinto eziningi ezisizungezile zinamagama avamile namagama amahle.Isibonelo, isitshalo esiluhlaza esaziwa kakhulu ngokuthi "izithombo zeLala" sibizwa ngobuhle ngokuthi "humus".Eqinisweni, amapulasitiki nawo anamagama amahle.
Amapulasitiki angama-monomers njengezinto zokusetshenziswa futhi afakwe i-polymerized nge-polyaddition noma i-polycondensation.Zinokumelana okuphakathi kokuguquguquka futhi ziphakathi phakathi kwemicu nerabha.Akhiwe ngama-resin okwenziwa kanye nama-fillers, ama-plasticizers, ama-stabilizers, ama-lubricant., izingulube nezinye izithasiselo.Ingxenye eyinhloko yepulasitiki yi-resin.I-resin ibhekisela kwinhlanganisela ye-polymer engazange ihlanganiswe nezithasiselo ezihlukahlukene.Igama elithi resin ekuqaleni laliqanjwe ngama-lipids akhiqizwa izilwane nezitshalo, njenge-rosin ne-shellac.I-resin ibalelwa ku-40% kuya ku-100% wesisindo esiphelele samapulasitiki.Izakhiwo eziyisisekelo zamapulasitiki zinqunywa ikakhulukazi uhlobo lwe-resin, kodwa izithasiselo nazo zidlala indima ebalulekile.Amanye amapulasitiki akhiwe ngokuyisisekelo ngama-synthetic resins, angenayo noma izithasiselo ezincane, njenge-plexiglass.
Igama elihle lepulasitiki lithi: i-synthetic resin.I-synthetic resin iwuhlobo lwenhlanganisela ye-polymer eyenziwe ngokwenziwa.Iwuhlobo lwenhlaka enezici noma ezedlula izici zemvelo ze-resin yemvelo.Ukusebenza kwayo okubaluleke kakhulu ukwakhiwa kwamapulasitiki.Ukuze kube lula ukucubungula nokuthuthukisa ukusebenza, izithasiselo zivame ukungezwa, futhi ngezinye izikhathi zisetshenziselwa ukucubungula, ngakho-ke zivame ukufana namapulasitiki.Ekusetshenzisweni okusebenzayo, asetshenziswa ngokufanayo namapulasitiki.
Ngakho-ke, bangane, lapho abantu bekhuluma nge-resin yokwenziwa, khumbula ukuthi empeleni bakhuluma ngepulasitiki ~
