Iresin ikakhulu ibhekisa kwikhompawundi ephilayo eyomeleleyo, isemi-solid okanye i-pseudo-solid kwiqondo lobushushu begumbi, kwaye ngokubanzi inoluhlu lokuthamba okanye lokunyibilika emva kokuba ishushu.Xa ithambe, ichaphazeleka ngamandla angaphandle kwaye ngokuqhelekileyo inomkhuba wokuhamba.Ngengqiqo ebanzi, apho iipolymers njengematriksi yeplastiki zonke zinokuba ziintlaka.

Iplastiki ibhekisela kwizinto eziphilayo zepolymer ezenziwe ngokubumba kunye nokucubungula nge-resin njengenxalenye ephambili, yongeza izongezo ezithile okanye ii-agent ezincedisayo.

Iintlobo eziqhelekileyo zeeplastiki:

Iiplastiki eziqhelekileyo: i-polyethylene, i-polyvinyl chloride, i-polystyrene, i-polymethylmethacrylate.

Iiplastiki zobunjineli ngokubanzi: i-polyester amine, i-polycarbonate, i-polyoxymethylene, i-polyethylene terephthalate, i-polybutylene terephthalate, i-polyphenylene ether okanye i-polyphenylene ether elungisiweyo, njl.

Iiplastiki zobunjineli ezikhethekileyo: i-polytetrafluoroethylene, i-polyphenylene sulfide, i-polyimide, i-polysulfone, i-polyketone kunye ne-polymer ye-crystal engamanzi.

Iiplastiki ezisebenzayo: iiplastiki eziqhubayo, iiplastiki zepiezoelectric, iiplastiki zemagnethi, iifiber zeplastiki zamehlo kunye neeplastiki zamehlo, njl.

Iiplastiki ze-thermosetting ngokubanzi: i-phenolic resin, i-epoxy resin, i-polyester engaxutywanga, i-polyurethane, i-silicone kunye neplastiki ye-amino, njl.

Iipuni zeplastiki, enye yeemveliso zethu eziphambili zeplastiki, zicutshungulwa ukusuka kwibakala lokutya le-PP izinto eziluhlaza.Kubandakanywaiingqayi zeplastiki, izinti zokuphefumla ngeempumlo, zonke izixhobo zonyango okanye zaselabhoratri okanye izitya zasekhitshini zasekhaya zikwayimathiriyeli yodidi lokutya.

Iindawo zokusetyenziswa kweplastiki:

1. Izinto zokupakisha.Izinto zokupakisha zezona zisetyenziswa kakhulu kwiiplastiki, zibalelwa ngaphezu kwe-20% yetotali.Iimveliso eziphambili zahlulwe zibe:

(1) Iimveliso zefilimu, ezifana nefilimu yokupakisha elula kunye nenzima, ifilimu yesithintelo, ifilimu eshushu, ifilimu yokuzincamathela, ifilimu echasene nomhlwa, ifilimu yokukrazula, ifilimu ye-air cushion, njl.

(2) Iimveliso zebhotile, ezifana neebhotile zokupakisha ukutya (ioli, ibhiya, i-soda, iwayini emhlophe, iviniga, i-soy sauce, njl.), iibhotile zokuthambisa, iibhotile zamayeza kunye neebhotile ze-reagent chemical.

(3) Iimveliso zebhokisi, ezifana neebhokisi zokutya, i-hardware, imisebenzi yezandla, izixhobo zenkcubeko kunye nezemfundo, njl.

(4) Iimveliso zekomityi, ezifana neekomityi zesiselo ezilahlwayo, iikomityi zobisi, iikomityi zeyogathi, njl.

(5) Iimveliso zebhokisi, ezifana neebhokisi zebhiya, iibhokisi zesoda, iibhokisi zokutya

(6) Iimveliso zeengxowa, ezifana neebhegi kunye neebhegi ezilukiweyo

2. Iimfuno zemihla ngemihla

(1) Iimveliso ezahlukeneyo, ezifana nezitya, imigqomo, iibhokisi, iibhaskithi, iipleyiti, izitulo, njl.

(2) Amanqaku enkcubeko kunye nezemidlalo, ezifana neepeni, iirula, i-badminton, i-tennis yetafile, njl.

(3) Ukutya kwempahla, njengezihlangu zeembadada, isikhumba sokwenziwa, isikhumba sokwenziwa, amaqhosha, iinwele, njl.

(4) Izixhobo zekhitshi, ezinjengamacephe, iibhodi zokusika, iifolokhwe, njl.

Nantso ke okwanamhlanje, sobonana kwixesha elizayo.
