Ukuveliswa kweplastiki
Iplastiki - Igama livela kwisiGrike (plastikos), elithetha ukuba lifanelekile ukubumba, oko kukuthi, iplastiki kwinkqubo yokuvelisa, evumela ukuba baphoswe.
Yenza iindidi ngeendidi zeemilo. Ukuveliswa kweplastiki kunokubizwa ngokuba ngumsebenzi wobugcisa boluntu kwinkulungwane yama-20, emva kweminyaka engaphezu kwe-100 yophuhliso, iplastiki ibikho kuyo yonke indawo Ibe yinto eyimfuneko kuluntu oluphucukileyo lwanamhlanje.
Paxsing
"I-Paksin" yayiyeyokuqala ukufunyanwa - iplastiki ekhulayo. Ngeminyaka yoo-1850, isazi samachiza esiNgesi uParkes wayephanda ngeendlela zokusetyenzwa kwe-collodion, i-collodion exutywe ngengozi kunye ne-camphor, idala i-. Isixhobo esiqinileyo esikwaziyo ukugoba. Kwaye wayithiya igama elithi 'Paksin'. Ukusetyenziswa kweepaki "iPaxine" yenza yonke into ukusuka kwi-combs ukuya kumaqhosha ukuya kwizinto zobucwebe, kwaye abantu babeyithanda.
celluloid
Kwiminyaka ye-1860, uHiatt waphucula inkqubo yokuvelisa "iPaksin" kwaye wayibiza ngokuthi "Celluloid". "I-Ceruloc yayisetyenziselwa ukuveliswa kweebhola zebhiliyoni, kodwa njengoko imarike yeplastiki iqhubeka isanda, "iCeruloc" yenziwa kwiintlobo ezahlukeneyo.
Imveliso. "I-Celluloid" yiplastiki eyenziwe ngumntu, eneempawu ezinokutsha, ngoko ke uluhlu lwemveliso yemveliso lulinganiselwe.
Ukuveliswa kwe-polyethylene
Ngo-1933, u-Reginald Gibson kunye no-Eric Fawcett we-ICI bafumanisa ukuba i-ethylene inokupolymerized kwi-polyethylene phantsi koxinzelelo oluphezulu.Le ndlela yaziwa ngokuba yindlela yoxinzelelo oluphezulu, kunye nokuveliswa kwemveliso kwaqala ngo-1939. i-polyethylene (LDPE) kunye ne-high-density polyethylene (HDPE) kwiifom ezimbini. Ekuqaleni kweminyaka yoo-1950, iAmerican Phillips Oil Company yafumanisa i-chromium oxide, njenge-catalyst, i-ethylene inokwenziwa ipolymerized ukuvelisa i-polyethylene exineneyo phantsi koxinzelelo oluphakathi, kwaye imveliso yemizi-mveliso yaphunyezwa ngo-1957. Kwiminyaka yee-'60s, inkampani yaseKhanada yaseDuPont yaqala ukusebenzisa i-ethylene kunye ne-ethylene. i-a-Low density poly (B) intsimi yalungiswa ukusuka kwi-olefin ngendlela yesisombululo. I-PE inexabiso eliphantsi, iyaguquguquka, incamathele kwaye iyamelana nokubola kweekhemikhali. I-LDPE isetyenziswa ekwenzeni iifilimu kunye nezinto zokupakisha I-HDPE isetyenziswa kakhulu ukwenza izikhongozeli, imibhobho kunye namalungu emoto.
Inkampani yethu isebenzisa iimveliso ze-polyethylene
I-Zhongshang huangpu guoyu imveliso yeplastiki yeemveliso zeplastiki Ishishini eliphambili lolwahlulo lishishini leplastiki, kodwa ekukhetheni izixhobo ziya kukhetha i-polyethylene, Isizathu sokuba i-Polyethylene yayo ayinavumba, ayinayo ityhefu, ivakalelwa njenge-wax, inokumelana nobushushu obuphantsi (ubuncinci bokusetyenziswa. ubushushu bunokufikelela ku--100 ~ -70 ° C), ukuzinza kweekhemikhali ezilungileyo, ukuchasana nobuninzi be-asidi kunye nokukhukuliseka kwe-alkali (ayikwazi ukumelana ne-asidi eneempawu ze-oxidation). I-solvents enganyibilikiyo ngokubanzi kubushushu begumbi, ukufunxwa kwamanzi aphantsi, ukugqunywa kombane okulungileyo.. Esi sisiqinisekiso esingcono kubathengi abathenga iimveliso zethu, okubaluleke ngakumbi, i-polyethylene yinto ehambelana nokusingqongileyo, kwaye ungcoliseko lokusingqongileyo kuluntu lwanamhlanje luya lusiba ngakumbi kwaye nzulu ngakumbi. IJapan ayizinanzanga izithintelo zamazwe ngamazwe zokulahlwa kwenkunkuma yenyukliya, eyonakalisa indalo esingqongileyo. Into esinokuyenza kukwenza konke okusemandleni ethu ukukhusela indawo esinokuhlala kuyo
