Plasitiki ya Polyethylene (PE)

* PE ni plastiki ya polyethylene, ishobora gukorwamo filime ya pulasitiki, imifuka ya pulasitiki n'ibice bitandukanye. Kugira ngo bigabanye umwanda w'umweru, ibintu byangiza bishobora kongerwa kuri plastiki kugira ngo bigerweho mu kwangirika vuba, ubwo bwoko bwa polyethylene bwitwa pulasitiki itangiza ibidukikije. Ni pulasitiki yoroheje, iramba, kandi ni imwe muri pulasitiki ikunze gukorwa cyane.

* Ibikoresho bya pulasitiki cyangwa ibice byayo byihariye

Plasitiki ya PE ni iki?

Polyethylene yitwa PE, ni resine ya thermoplastic ikorwa na polymerization ya ethylene, ni imiterere y'ibinyabutabire bya polymer byoroshye cyane, ibikoresho bya polymer bya PE polyethylene bikoreshwa cyane ku isi, polymerization ya ethylene, hakurikijwe ubucucike butandukanye bugabanyijemo polyethylene ifite ubucucike bwinshi, polyethylene ifite ubucucike buri hagati na polyethylene ifite ubucucike buke.

Polyethylene nta mpumuro igira, ntabwo ari uburozi, yumva ameze nk'ibishashara, ifite ubushobozi bwo kurwanya ubushyuhe buke cyane (ubushyuhe buke bukoreshwa kugeza kuri -100 ~ -70 ° C), ifite ubushobozi bwo kudahinduka mu binyabutabire, ishobora kwihanganira aside nyinshi na alkali (ntirwanya ogisijeni y'aside). Ntishobora gushonga mu bintu byose bishongesha mu bushyuhe bw'icyumba, ifata amazi make, ifite ubushobozi bwo gukingira amashanyarazi neza.

PE ikorwa ite?

Polyethylene ikorwa muri polymerization ya monomer ya ethylene (cyangwa ethene). Imiyoboro ya PE ikorwa hifashishijwe polymerization yongerwamo cyangwa radical. Uburyo bushoboka bwo gukora ni ubu:

Ziegler-Natta Polymerization na

Katalise ya Metallocene

Ese resins za PE zirimo uburozi?

Mu buryo bukomeye, Polyethylene ifatwa nk'ikintu kidahumanye kandi kidahumanya. Ishobora kuba uburozi iyo ihumekwa cyangwa ikanyikwa nk'umwuka cyangwa amazi (ni ukuvuga mu gihe cyo kuyikora).

Ni ubuhe bwoko busanzwe bwa PE?

Bitewe n'ubucucike bwayo n'uburyo iteye, amanota atandukanye ya PE ashobora kugira imikorere itandukanye cyane hagati yayo.

Bityo rero, amanota ya PE ashyirwa mu byiciro bikurikira.

Verisiyo z'amashami

Polyethylene yo mu bwoko bwa “Low-density” (LDPE)

Polyethylene ifite ubucucike buke (LLDPE)

Verisiyo z'umurongo

Polyethylene ifite ubucucike bwinshi (HDPE)

Polyethylene ifite uburemere buhanitse cyane (UHMWPE)

Polyethylene ifatanye n'izindi (PEX cyangwa XLPE)

Byongeye kandi, hari n'ubundi bwoko bwa PE buboneka nka:

Polyethylene ifite ubucucike buringaniye (MDPE)

Polyethylene yo mu bwoko bwa Ultra-density low (ULDPE)

Polyethylene ifite uburemere buhanitse bwa molekile (HMWPE)

Polyethylene ya Metallocene (mPE)

Polyethylene ifite chlorine (CPE)
