Izinto eziluhlaza zeplastiki yi-resin yokwenziwa, ekhutshwe kwaye ihlanganiswe kwi-petroleum, igesi yendalo okanye i-coal cracking.I-oyile, igesi yendalo, njl.njl. ziboliswa zibe yi-low-molecular organic compounds (ezifana ne-ethylene, propylene, styrene, ethylene, vinyl alcohol, njl.) , kwaye ke iiplasticizers, Lubricants, fillers, njl., zingenziwa kwizinto ezahlukeneyo zeplastiki ekrwada.Ngokuqhelekileyo, i-resin zicutshungulwa zibe yi-granules ukuze kube lula ukusetyenziswa.Ngokuqhelekileyo zibunjwe kwizixhobo ezinemilo ethile phantsi kweemeko zokufudumeza kunye noxinzelelo.
Iimpawu ezibonakalayo zeplastiki.Kukho iintlobo ezininzi zeepropathi ezibonakalayo zeplastiki, ezi zilandelayo zimbalwa kuphela ezifuna ukuqondwa ngokufunda iteknoloji ye-toning:
1. Uxinaniso olunxulumeneyo: Ubuninzi obunxulumene nomlinganiselo wobunzima besampulu kubunzima bomthamo ofanayo wamanzi kwiqondo lobushushu elithile, kwaye yindlela ebalulekileyo yokuchonga imathiriyeli ekrwada.
2. Izinga lokufunxa amanzi: Iplastiki ekrwada yenziwe isampuli yobungakanani obuchaziweyo, intywiliselwe emanzini adityanisiweyo kunye nobushushu obuyi (25±2) ℃, kunye nomlinganiselo wobungakanani bamanzi afunxwe yisampulu kwimathiriyeli ekrwada. emva kweeyure ezingama-24.Ubungakanani bokufunxa kwamanzi bunquma ukuba iplastiki eluhlaza idinga ukubhaka kunye nobude bexesha lokubhaka.
3. Ubushushu bokubumba: Ubushushu bokubumba bubhekisa kubushushu obunyibilikayo beresin ekrwada
4. Iqondo lokushisa lokubola: Iqondo lokushisa lokubola libhekiselele kwiqondo lokushisa apho ikhonkco ye-macromolecular yeplastiki iphuka xa ishushu, kwaye ikwasinye sezibonakaliso zokuchonga ukuxhathisa ukushisa kweplastiki.Xa ubushushu obunyibilikayo budlula ubushushu bokubola, uninzi lwezixhobo eziluhlaza ziya kuba tyheli, zide zitshiswe kwaye zibe mnyama, kwaye amandla emveliso aya kuncitshiswa kakhulu.
