Igishashara cya polyethylene, bizwi kandi nk'ibishashara bya polymer, bikoreshwa cyane kubera kurwanya ubukonje buhebuje, kurwanya ubushyuhe, kurwanya imiti, no kwihanganira kwambara.Mu musaruro usanzwe, iki gishashara gishobora kongerwaho mu buryo butaziguye gutunganya polyolefin nkinyongera, ishobora kongera imikorere no gutunganya ibicuruzwa.Nka mavuta, ifite imiti ihamye kandi ifite amashanyarazi meza.Ugereranije na PVC nandi mavuta yo hanze, ibishashara bya polyethylene bifite imbaraga zo gusiga imbere imbere.
Ibishashara bya Fischerigizwe cyane cyane n'umurongo, wuzuye karubone nyinshi ya karubone ifite uburemere bugereranije hagati ya 500 na 1000, itanga iyi miti hamwe nuburyo bwiza bwa kirisiti, aho gushonga cyane, kugabanuka gushonga, amavuta make, kwinjira cyane, kugenda gake, gushonga gake ubukonje, gukomera, kwambara birwanya, hamwe no guhagarara neza.
Itandukaniro rikomeye hagati y’ibishashara bya Fischer Tropsch n’ibishashara rusange bya polyethylene ni uko:
(1) Uburemere bwa molekile.Uburemere bwa molekuline bwibishashara bya Fischer Tropsch buri munsi cyane ugereranije n’ibishashara bya PE, bifite iminyururu mike ishami hamwe na kristu ndende.Biroroshye gucengera mumurongo mwinshi wa macromolecular, bigabanya cyane ububobere bwashonga.Ifite kwimuka muke mugihe cyo gutunganya ningaruka zigaragara zo gusiga mubyiciro byanyuma.
.
(3) Ubukonje bwibishashara bya Fischer Tropsch buri munsi cyane ugereranije n’ibishashara bya PE.Gusa hafi 10. Umubare muto urashobora kugera kubintu bimwe byo gusiga.Imikoreshereze ni 70-80% gusa yibishashara bya PE.Ibishashara bya Fischer Tropsch bifite aho bihurira na PVC kandi birashobora gukoreshwa nkamavuta yimbere ninyuma.Irashobora gukoreshwa nkamavuta meza yimbere kugirango igenzure neza imiterere yimisatsi, itere imbere, igabanye ubukana hamwe nogushonga, bityo bitezimbere ubushyuhe bwumuriro.Muri icyo gihe, bitewe na kirisiti yacyo nini kandi ifite umurongo muremure, ibishashara bya Fischer Tropsch bituma ibicuruzwa bya PVC bigera kubintu byiza bifatika kandi bitunganyirizwa.Ukurikije ibikenewe, inzira ya Fischer Tropsch irashobora guhuza alkane hamwe nuburebure butandukanye bwurunigi kugirango ihindure uburemere bwa molekuline yibicuruzwa byanyuma hanyuma ikore urukurikirane rwibicuruzwa.
Uburyo nyamukuru bwibikorwa byamavuta yo hanze
Mubisanzwe, amavuta yo hanze ya PVC nigishashara kinini cyo gushonga gifite ibishashara bidafite polarite cyangwa polarite nkeya, ugereranije hejuru ya 50-200 ℃, hamwe nuburemere bwa molekile nini.
Uburyo bwibikorwa nugukoresha kutabangikanya kugirango habeho amavuta yo kwisiga hanze yubuso bwa PVC yashonga cyangwa itemba, bigateza ubushyamirane hagati yimiterere yibice bitemba no hagati yo gushonga hamwe nicyuma.Biroroshye kugwa mubushyuhe bwinshi, ariko ntibyoroshye kugwa mubushyuhe bwicyumba.
Ingaruka zamavuta kubicuruzwa
Amavuta yo hanze, plastike kuva yihuta kugeza gahoro, imikorere yibicuruzwa kuva hejuru kugeza hasi, hamwe no gutembera kuva mubukene kugeza mubyiza bidahwitse.
Ku cyiciro cyambere cyo gutunganya ibicuruzwa, mugihe uduce duto twa resin turimo kunyerera hamwe, ingingo yo gushonga yo gusiga hanze ni ndende kandi nta gushonga, bitazadindiza plastike.Mu cyiciro cyo hagati na nyuma yo gutunganya, ubushyuhe bwo gushonga buriyongera, kandi amavuta yo kwisiga yo hanze yashonga hagati yo gushonga, gutinda neza plastike no kunoza neza ibyuma, bikarinda plastike ikabije gushonga kandi bigatanga imikorere myiza yo kumeneka.
