Hafi ya thermoplastique irashobora gutunganyirizwa firime hamwe no guhumeka, firime ya pulasitike ya pulasitike ni ugusunika mu muyoboro muto, hanyuma ugakubita umwuka uhumeka kugirango uhuhure amashanyarazi, nyuma yo gukonjesha kugirango urangize igishushanyo mbonera cyibicuruzwa bya membrane, ubu bwoko bwa firime hagati firime yerekanwe hamwe no kurambura firime: imbaraga ziruta kurambura firime, gufunga ubushyuhe nabi kuruta kurambura firime.

Hariho ubwoko bwinshi bwa firime yakozwe nuburyo bwo guhumeka, nkaubukana buke bwa polyethylene (LDPE), umurongo wa polyethylene (LLDPE), polypropilene (PP), polyethylene yuzuye (HDPE), nylon (PA), Ethylene Ethylene acetate copolymer (EVA), nibindi. .

1. Ibikoresho byatoranijwe byatoranijwe bigomba guhuhwa mu rwego rwa firime polyethylene resin ibice, birimo urugero rukwiye rwo korohereza, kugirango firime ifungurwe.

Indangantego ya resin 2 yo gushonga (MI) ntishobora kuba nini cyane, indangagaciro yo gushonga (MI) nini cyane, ibishishwa bya resin yashongeshejwe ni bito cyane, uburyo bwo gutunganya ni buke, uburyo bwo gutunganya biragoye kubigenzura, firime ya resin irakennye, ntibyoroshye gutunganya muri firime;Byongeye kandi, indangagaciro yo gushonga (MI) nini cyane, ugereranije uburemere bwa molekile igabanijwe ya polymer iragufi cyane, kandi imbaraga za firime ni mbi.Kubwibyo, ugomba guhitamo gushonga (MI) ni ntoya, kandi ugereranije uburemere bwa molekuline ikwirakwizwa ryibikoresho bigari bya resin, kugirango byuzuze ibisabwa muri firime, ariko kandi urebe neza uburyo bwo gutunganya ibiranga.Blow molding polyethylene isanzwe ikoreshwa mubipimo byo gushonga (MI) hagati ya 2 na 6g / 10min ibikoresho bya polyethylene.

Gukubita firime ya firime ni nkibi bikurikira:

Hopper yapakurura ibikoresho bya pulasitiki ya extrait
