Ni ubuhe bwoko bw'imifuka iboshye

Polyethylene (PE) ikorerwa cyane mubihugu byamahanga, kandiPolypropilene(PP) ikorerwa cyane mubushinwa.Nubwoko bwa resmoplastique resin ikorwa na polymerisation ya Ethylene.Mu nganda, copolymers ya Ethylene hamwe na α - olefine nayo irimo.Polyethylene nta mpumuro nziza, nontoxic, ibishashara, hamwe nubushyuhe bwo hasi cyane (ubushyuhe bwo hasi burashobora kugera - 70 ～ - 100 ℃), imiti myiza ihamye, irwanya aside nyinshi hamwe nisuri ya alkali (idashobora kurwanya aside oxyde), idashobora gushonga mumashanyarazi rusange. ku cyumba cy'ubushyuhe, kwinjiza amazi make no kubika amashanyarazi meza;ariko polyethylene yunvikana cyane nibidukikije (ibikorwa bya chimique na mashini) Kurwanya gusaza ubushyuhe ni bibi.Imiterere ya polyethylene iratandukanye bitewe nubwoko butandukanye, ahanini bitewe nuburyo bwa molekile nubucucike.Ubucucike butandukanye (0.91-0.96 g / cm3) bwibicuruzwa birashobora kuboneka muburyo butandukanye bwo gukora.

Polyethylene irashobora gutunganywa nuburyo bwo kubumba ibintu rusange (reba gutunganya plastike).Irakoreshwa cyane mugukora firime, kontineri, imiyoboro, monofilaments, insinga ninsinga, ibikenerwa bya buri munsi, nibindi birashobora kandi gukoreshwa nkibikoresho bikoresha insuline nyinshi kuri TV, radar, nibindi. Hamwe niterambere ryinganda za peteroli, umusaruro ya polyethylene yateye imbere byihuse, kandi ibisohoka bingana na 1/4 cy'umusaruro wose wa plastiki.Mu 1983, umusaruro wose wa polyethylene ku isi wari 24,65 MT, naho uruganda rwubakwa ni 3.16 Mt.

Polypropilene(PP)

Amashanyarazi ya termoplastique yabonetse na polymerisation ya propylene.Hano hari ibishushanyo bitatu byibintu bya isotactique, ibintu bidasanzwe nibintu bya syndiotactique.Ibintu bya Isotactique nibice byingenzi byibicuruzwa byinganda.Polypropileneikubiyemo kandi cololymers ya propylene hamwe na Ethylene nkeya.Mubisanzwe bisobanutse bitagira ibara rikomeye, impumuro idafite uburozi.Bitewe nuburyo busanzwe hamwe na kristu yo hejuru, gushonga ni hejuru ya 167 and, kandi ibicuruzwa birashobora guhindurwa na parike.Ubucucike ni 0,90g / cm3, aribwo plastiki rusange yoroshye.Kurwanya ruswa, imbaraga zingana 30MPa, imbaraga, gukomera no gukorera mu mucyo biruta polyethylene.Ingaruka ni ubukonje buke bwo kurwanya ubushyuhe no gusaza byoroshye, bishobora kuneshwa no guhindura no kongeramo antioxydeant.

Ibara ryaimifukamuri rusange cyera cyangwa cyera cyera, kidafite uburozi kandi kitaryoshye, kandi muri rusange ntabwo cyangiza umubiri wumuntu.Nubwo ikozwe muri plastiki zitandukanye za chimique, kurengera ibidukikije birakomeye, kandi imbaraga zayo zo gutunganya ni nini;

Amashashis zikoreshwa cyane, cyane mugupakira no gupakira ibintu bitandukanye, kandi bikoreshwa cyane mubikorwa;

PlastikeimifukaniPolypropileneresin nkibikoresho byingenzi bibisi, bisohoka kandi bikaramburwa mumashanyarazi, hanyuma bikabikwa bigakorwa mumufuka.

Gukora plastikeimifukaikozwe mu mwenda uboshye wa pulasitike ukoresheje kaseti.

Uruhererekane rwibicuruzwa bikoreshwa mugupakira ifu cyangwa granular ibikoresho bikomeye nibintu byoroshye.Igikoresho cya plastikiimifukaigabanijwemo kabiri mu mufuka umwe na batatu mu mufuka umwe ukurikije ibintu nyamukuru bigize.

Ukurikije uburyo bwo kudoda, irashobora kugabanwa mu kudoda umufuka wo hasi, kudoda umufuka wo hasi, gushiramo igikapu n umufuka wo kudoda.

Ukurikije ubugari bukomeye bwumufuka, irashobora kugabanywamo 350, 450, 500, 550, 600, 650 na 700mm, kandi ibisobanuro byihariye byemeranijwe nuwabitanze nuwabisabye.
