Izinto ezininzi ezisingqongileyo zinamagama aqhelekileyo kunye namagama amahle.Umzekelo, isityalo esiluhlaza esaziwa ngokuba yi "Lala seedlings" sibizwa ngokuba yi "humus".Enyanisweni, iiplastiki nazo zinamagama amahle.
Iiplastiki ziimonomers njengemathiriyeli ekrwada kwaye zenziwe i-polymerized nge-polyaddition okanye i-polycondensation.Banokumelana okuphakathi kwi-deformation kwaye baphakathi phakathi kwe-fibers kunye ne-rubber.Ziqulunqwe ngee-resin zokwenziwa kunye nezizaliso, i-plasticizers, i-stabilizers, i-lubricant., ii-pigments kunye nezinye izongezo.Inxalenye ephambili yeplastiki yi-resin.I-resin ibhekisa kwikhompawundi ye-polymer engazange ixutywe kunye nezongezo ezahlukeneyo.Igama elithi resin ekuqaleni lalibizwa ngokuba yi-lipids efihliweyo zizilwanyana kunye nezityalo, ezifana ne-rosin kunye ne-shellac.I-resin yenza malunga ne-40% ukuya kwi-100% yobunzima bubonke beeplastiki.Iipropati ezisisiseko zeeplastiki zichongwa ngokukodwa luhlobo lwe-resin, kodwa izongezo nazo zidlala indima ebalulekileyo.Ezinye iiplastiki ngokwesiseko zenziwe ngeereyini zokwenziwa, ezingenazo okanye zincinci izongezo, njengeplexiglass.
Igama elihle leplastiki yile: i-synthetic resin.I-Synthetic resin luhlobo lwekhompawundi eyenziwe ngepolymer eyenziweyo.Luhlobo lwe-resin ene-resin okanye engaphezulu kweempawu zendalo ze-resin yendalo.Eyona nto ibaluleke kakhulu ukusetyenziswa kwayo kukwenziwa kweeplastiki.Ukuze kuququzelelwe ukusetyenzwa kunye nokuphucula ukusebenza, izongezo zihlala zongezwa, kwaye ngamanye amaxesha zisetyenziselwa ngokuthe ngqo ukusetyenzwa, ngoko zihlala zifana neeplastiki.Kwiinkqubo ezisebenzayo, zisetyenziswa ngokufanayo kunye neeplastiki.
Ke, bahlobo, xa abantu bethetha nge-synthetic resin, khumbula ukuba ngenene bathetha ngeplastiki ~
