Ukusungulwa kwepulasitiki
Ipulasitiki - Igama livela kwelesiGrikhi (plastikos), okusho ukuthi kufanelekile ukubunjwa, okungukuthi, ipulasitiki enqubweni yokukhiqiza, evumela ukuthi ziphonswe.
Yenza ukuhlukahluka kobumo. Ukusungulwa kwepulasitiki kungabizwa ngokuthi ubuciko besintu ekhulwini lama-20, ngemva kweminyaka engaphezu kweyi-100 yentuthuko, ipulasitiki isikhona yonke indawo Sekuyimpahla eluhlaza engabalulekile emphakathini wanamuhla ophucuzekile.
I-Paxsing
"I-Paksin" yaba ngowokuqala ukutholakala - ipulasitiki ekhulayo. Ngawo-1850, usokhemisi oyiNgisi uParkes wayecwaninga izindlela zokucubungula i-collodion, i-collodion exutshwe ngengozi ne-camphor, kwakheka a. Impahla eqinile ekwazi ukugoba. Futhi wayiqamba ngokuthi 'Paksin'. Ukusetshenziswa kwamapaki "i-Paxine" yenze yonke into kusukela kumakama kuya ezinkinobho kuya ebucwebeni, futhi abantu babekuthanda.
i-celluloid
Ngawo-1860, u-Hiatt wathuthukisa inqubo yokukhiqiza "i-Paksin" futhi wayiqamba kabusha ngokuthi "i-Celluloid". "I-Ceruloc ekuqaleni yayisetshenziswa ekwenzeni amabhola e-billiard, kodwa njengoba imakethe yepulasitiki iqhubeka nokukhula, "i-Ceruloc" yenziwa izinhlobo ezihlukahlukene.
Umkhiqizo. "I-Celluloid" iyipulasitiki eyenziwe ngumuntu, enezici ezivuthayo, ngakho ububanzi bokukhiqiza umkhiqizo bulinganiselwe.
Ukusungulwa kwe-polyethylene
Ngo-1933, u-Reginald Gibson no-Eric Fawcett be-ICI bathola ukuthi i-ethylene ingenziwa i-polymerized ibe i-polyethylene ngaphansi kwengcindezi ephezulu.Le ndlela yaziwa ngokuthi indlela yokucindezela okuphezulu, futhi ukukhiqizwa kwezimboni kwaqala ngo-1939. i-polyethylene(LDPE) ne-high-density polyethylene (HDPE) ngezindlela ezimbili. Ekuqaleni kwawo-1950, i-American Phillips Oil Company yathola i-chromium oxideNjenge-catalyst, i-ethylene ingenziwa i-polymerized ukuze ikhiqize i-polyethylene ephezulu ngaphansi kwengcindezi ephakathi, futhi ukukhiqizwa kwezimboni kwafinyelelwa ngo-1957. Ngawo-'60s, inkampani yase-Canada yaseDuPont yaqala ukusebenzisa i-ethylene kanye ne-ethylene. Inkambu ye-a-Low density poly (B) yalungiswa kusuka ku-olefin ngendlela yesisombululo. I-PE ishibhile, iyaguquguquka, inamathele futhi imelana nokugqwala kwamakhemikhali. I-LDPE isetshenziswa ekwenzeni amafilimu nezinto zokupakisha I-HDPE isetshenziswa kakhulu ukwenza iziqukathi, amapayipi nezingxenye zezimoto.
Inkampani yethu isebenzisa imikhiqizo ye-polyethylene
I-Zhongshang huangpu guoyu imboni yemikhiqizo yepulasitiki Ibhizinisi eliyinhloko lesigaba yimboni yepulasitiki, kodwa ekukhetheni izinto ezizokhetha i-polyethylene, Isizathu yi-Polyethylene yayo engenaphunga, engeyona enobuthi, izwakala njengengcina, inokumelana okuhle kakhulu nokushisa okuphansi (ukusetshenziswa okuncane izinga lokushisa lingafinyelela -100~-70°C), ukuzinza okuhle kwamakhemikhali, ukumelana nokuguguleka kwe-asidi ne-alkali (okungamelani ne-asidi enezakhiwo ze-oxidation). Angancibiliki ngokujwayelekile ngezincibilikisi ezivamile ekamelweni lokushisa, ukumuncwa kwamanzi aphansi, ukufakwa kahle kukagesi. Lesi isiqinisekiso esingcono samakhasimende athenga imikhiqizo yethu, Okubaluleke nakakhulu, i-polyethylene iyimpahla ehambisana nemvelo, futhi ukungcoliswa kwemvelo emphakathini wanamuhla kuya ngokuya kuyanda futhi sina kakhulu. I-Japan ayizinaki imingcele yamazwe ngamazwe yokuchithwa kwemfucuza yenuzi, elimaza imvelo. Esingakwenza wukwenza konke okusemandleni ethu ukuvikela imvelo esingaphila kuyo
