Zvinhu zvakawanda zvakatipoteredza zvine mazita akajairika uye mazita anoyevedza.Semuenzaniso, chirimwa chegirini chinowanzozivikanwa se "Lala seedlings" inodaidzwa kuti "humus".Muchokwadi, mapurasitiki anewo mazita anoyevedza.
Plastiki imonomers seyakagadzirwa uye yakashongedzwa ne polyaddition kana polycondensation.Vane zvepakati kuramba deformation uye vari pakati pakati faibha uye rabha.Izvo zvinoumbwa nesynthetic resins uye fillers, plasticizers, stabilizers, lubricant., pigments uye zvimwe zvinowedzera.Chinhu chikuru chepurasitiki ndeye resin.Resin inoreva musanganiswa wepolymer usina kusanganiswa nezvimwe zvakasiyana-siyana.Izwi resin rakatanga kunzi lipids yakavanzwa nemhuka nemiti, senge rosin uye shellac.Resin inotora 40% kusvika 100% yehuremu hwese hwemapurasitiki.Izvo zvakakosha zvimiro zvepurasitiki zvinonyanya kutsanangurwa nemhando yeresin, asi zvekuwedzera zvinoitawo basa rakakosha.Mamwe mapurasitiki anonyanyo umbwa nemasynthetic resin, asina kana madiki ekuwedzera, senge plexiglass.
Iro zita rinoyevedza repurasitiki ndere: synthetic resin.Synthetic resin imhando yezvakagadzirwa zvepolymer musanganiswa.Iyo imhando yeresin ine kana inodarika hunhu hwechisikigo resin.Chikumbiro chayo chinonyanya kukosha ndechekugadzirwa kwepurasitiki.Kuti zvive nyore kugadzirisa nekuvandudza kushanda, zvinowedzera zvinowanzowedzerwa, uye dzimwe nguva zvinoshandiswa zvakananga kugadzirisa, saka zvinowanzofanana nemapurasitiki.Mumashandisirwo anoshanda, anoshandiswa zvakafanana nemapurasitiki.
Saka, shamwari, kana vanhu vachitaura nezve synthetic resin, rangarira kuti vari kutaura nezve plastiki ~
