Ipulasitiki yePolyethylene (PE)

* I-PE yipulasitiki ye-polyethylene, engenziwa ibe yifilimu yepulasitiki, izikhwama zepulasitiki kanye nezingxenye ezahlukahlukene. Ukuze kuncishiswe ukungcola okumhlophe, izinto ezibangela ukubola zingangezwa kupulasitiki ukuze kufezwe injongo yokubola okusheshayo, lolu hlobo lwe-polyethylene lubizwa ngokuthi amapulasitiki anobungani nemvelo. Lulula, luhlala isikhathi eside, futhi lungenye yepulasitiki evame ukukhiqizwa.

* Imikhiqizo noma izingxenye zepulasitiki ze-PE ezenziwe ngokwezifiso

Kuyini i-PE Plastic?

I-Polyethylene ebizwa ngokuthi i-PE, iyi-resin ye-thermoplastic ekhiqizwa yi-polymerization ye-ethylene, isakhiwo se-polymer compounds elula kakhulu ye-organic, izinto ze-polymer ze-PE ezisetshenziswa kakhulu emhlabeni, i-polymerization ye-ethylene, ngokusho kobuningi obuhlukene buhlukaniswe nge-polyethylene ephezulu, i-polyethylene ephakathi nendawo kanye ne-polyethylene ephansi.

I-Polyethylene ayinaphunga, ayinabo ubuthi, izwakala njenge-wax, inokumelana okuhle kakhulu nokushisa okuphansi (izinga lokushisa eliphansi kakhulu lokusetshenziswa elifika ku--100 ~ -70 ° C), ukuqina okuhle kwamakhemikhali, ingamelana nama-acid amaningi nama-alkali (ayimelani nezakhiwo ze-oxidizing ze-asidi). Ayincibiliki ezinyibilikisini ezijwayelekile ekushiseni kwegumbi, ukumuncwa kwamanzi amancane, ukuvikela ugesi okuhle kakhulu.

I-PE yenziwa kanjani?

I-Polyethylene yenziwe nge-polymerization ye-ethylene (noma i-ethene) monomer. Amaketanga e-PE akhiqizwa ngokungezwa noma nge-radical polymerization. Izindlela zokwenziwa ezingaba khona yilezi:

I-Ziegler-Natta Polymerization kanye

I-catalysis ye-Metallocene

Ingabe ama-resin e-PE anobuthi?

Uma iqinile, i-Polyethylene ibhekwa njengephephile futhi ayinabo ubuthi. Ingaba nobuthi uma iphefumulelwa futhi/noma imuncwa njengomhwamuko noma uketshezi (okungukuthi, ngesikhathi sezinqubo zokukhiqiza).

Yiziphi izinhlobo ezivamile ze-PE?

Kuye ngobuningi bayo kanye nokwakheka kwayo, amamaki e-PE ahlukene angaba nokusebenza okuhluke kakhulu komunye nomunye.

Ngakho-ke amamaki e-PE ahlukaniswa kanje.

Izinguqulo Ezihlanganisiwe

I-polyethylene ephansi (LDPE)

I-polyethylene ephansi enomugqa (LLDPE)

Izinguqulo Eziqondile

I-polyethylene enobukhulu obuphezulu (i-HDPE)

I-polyethylene enesisindo sama-molecule aphezulu kakhulu (UHMWPE)

I-polyethylene exhumene (i-PEX noma i-XLPE)

Ngaphezu kwalokho, kunezinye izinhlobo ze-PE ezifana nalezi:

I-polyethylene enobukhulu obuphakathi (i-MDPE)

I-polyethylene ephansi kakhulu (i-ULDPE)

I-polyethylene enesisindo sama-molecule aphezulu (i-HMWPE)

I-polyethylene ye-Metallocene (mPE)

I-polyethylene ene-chlorine (CPE)
