Polyethylene (pe) ni resin ya simatarile yahinduye ubuzima bwacu bwa buri munsi. Nicyo cyakoreshejwe cyane kwisi.
Yavumbuwe mu myaka ya za 1930, Pe yaje kurekurwa mu ntangiriro zayo. Uyu munsi, ni ibintu byingenzi munganda zitabarika.
Kubera gupakira kubaka, pe plastike igira uruhare rukomeye mu isi yacu ya none. Muri iyi nyandiko, tuzasesengura isi ishimishije ya pe plastiki.
Uziga kumiterere yacyo, ubwoko, hamwe na porogaramu itanga ntangarugero mubuzima bwacu bwa buri munsi.
Imiti n'imiterere ya pe plastiki
Formulaire
Polyethylene (pe) ifite imiti yoroshye ya chimique: (c2h4) n . Igizwe na atome ebyiri za karubone zihujwe na atome enye za hydrogen. 'N ' muri formula yerekana ibice bisubiramo iyi miterere. Iyo molekile nyinshi za Ethyne (C2H4) zifatanya, zikora iminyururu ndende, zikora polyethylene.
Imiterere ya moleCure ya pe
Inzira iri inyuma yibi yitwa polymeration . Monylene Monomeni ihuza urunigi, ahindura kuri pe. Iyi nzira irashobora kubaho binyuze muburyo butandukanye, nka Ziegler-Natta Polymeization cyangwa Ubusa Busa . Buri buryo bugira ingaruka kumuntu gato kumuntu wanyuma.
Imiterere ya molekale
Imiterere ya molekile igira uruhare runini mubikorwa byayo. Uburemere bwa molekile ya PE burashobora gutandukana cyane, kandi ibi bigira ingaruka ku mbaraga za plastike, guhinduka, no kuramba. Uburemere bwo hejuru bukunze kuvuga ibintu bikomeye, bigatuma bikwiranye na porogaramu ziremereye.
Ishami nikindi kintu cyingenzi. PE irashobora kugira urwego rutandukanye rwishami muminyururu yabyo. Amashami menshi, nko mu bucucike bwa polyethylene (ldpe) , ibisubizo byoroshye, byinshi byoroshye. Kurundi ruhande, ubucucike bwa polyethylene (HDPE) ifite amashami make, bituma bikomera no gukomera.
Crystallinity nayo igira ingaruka ku myitwarire ya PE. Byinshi kuri perstalline pe ni, gukomera cyane kandi bike birahinduka. Kurugero, HDPE, ifite urwego rwo hejuru rwa kirisiti, ikoreshwa mubicuruzwa bisaba imbaraga, nkibikoresho n'imiyoboro. Ibinyuranye, ldpe, hamwe na kristu yo hepfo, iratunganye kumifuka ya pulasitike na firime zitoroshye.
