Mugukoresha kwa polypropilene fibre izunguruka, ikoreshwa ryaibishashara bya polyethyleneni ntarengwa.Kubisanzwe bya filime nziza yo guhakana hamwe na fibre yo mu rwego rwo hejuru, cyane cyane kubwoya bworoshye nka denier nziza na BCF filaments ikwiranye no gushiraho amakoti hamwe n imyenda, ibishashara bya polypropilene bikunze guhitamo ibishashara bya polyethylene.
Sainuo-yera cyaneibishashara bya polipropilene, ubukonje buringaniye, gushonga hejuru, amavuta meza, hamwe no gutandukana neza.Kugeza ubu nubufasha buhebuje bwo gutunganya polyolefin, kurwanya ubushyuhe bwinshi, kandi birashoboka cyane.

Ubwa mbere, kubera kutabangikanya hagati ya polypropilene na polyethylene, biragoye cyane gushiraho imvange imwe muburyo bwa micro, bizatuma habaho gutandukana.
Icya kabiri, kubera ko aho gushonga ibishashara bya polyethylene biri munsi cyane ugereranije n’ibishashara bya polypropilene cyangwa polypropilene, biragoye guhangana nuburyo butandukanye bwo gushonga buranga polymers zombi.Ubusumbane hamwe na rheologiya idakwiye yibicuruzwa bishobora kuganisha kumpera yanyuma yo kuzunguruka.Bitewe nizi ngaruka mbi, imyenda yumubiri ya fibre iba mbi.
Muri iki gihe, birakenewe gukoresha ibishashara bya polypropilene hamwe nubukonje buke.Kubera ubukonje buke hamwe nubushuhe bwiza, irashobora guhanagura pigment mugihe gito.Byongeye kandi, mugihe ushushanya hamwe nubushyuhe bwa polypropilene fibre, urashobora kuboneka uhereye kubushyuhe bwo kuvura ubushyuhe (mubisanzwe nka 130c), buri mubushuhe bwubushyuhe bwibishashara bya polietilen.
Bitewe no guhindura imiterere ya kristaline ya fibre primaire ya polypropilene, birashobora kugaragara ko ibishashara bishongeshejwe bya polyethylene byinjira mumibiri ya fibre biva kuri matrike ya polypropilene, kandi ntabwo ari ibishashara byera gusa, ahubwo bizana na pigment bizazanwa hejuru.

Hanyuma, guhuza ibishashara bya polypropilene na polypropilene resin nibyiza mubice byombi bya micro na macro, kandi bigira ingaruka nke kumiterere yubukanishi.Hariho ubwoko bubiri bwibishashara bya polipropilene byakozwe na tekinoroji ya metallocene: imwe ni ibishashara bya polopropilene, naho ibikoresho fatizo ni propylene;Ibindi ni ibishashara bya polypropilene, ikoresha propylene na Ethylene nkibikoresho fatizo.
Muri rusange, ibishashara bya homopolypropilene bifite aho bishonga cyane hagati ya 140-160c, uburemere bwa molekile kuva ku bihumbi kugeza ku bihumbi mirongo, bihuye nubwiza bwa Brookfield kuva ku mirongo kugeza kuri byinshi byumye, byihuta cyane kandi bikomeye.Ikibanza cyo gushonga cya polipropilene igishashara gisanzwe kiri hagati ya 80-110 ℃, ubwiza bwa Brookfield ni amagana kugeza ku bihumbi cyangwa ibihumbi icumi, kandi uburemere bwa molekile bujyanye ni ibihumbi kugeza ku bihumbi.Bitewe no kongeramo etylene comonomer muri polipropilene ya pololymerize, ihungabanya gahunda isanzwe ya molekile ya propylene, kristu ya polipropilene ya kopolymerize iri hasi kandi ingingo yihariye yo gushonga nayo iri hasi.
Mu cyiciro cyo guswera cya pigment, ibishashara byo mu ibishashara bike bibaho vuba kandi neza kandi neza.Ariko birasabwa mugukuramo insinga.Mu cyiciro cya granulation, twizera ko ibishashara bifite ubukonje runaka, bushobora kwimura imbaraga zogosha hagati ya pigment na resin yashonga, kugirango pigment yatose ishobora kugabanwa neza mumashanyarazi.Muri iki gihe, birashobora gufatwa nkugukoresha ibishashara bya polypropilene bifite aho bishonga hamwe nigishashara cya polypropilene gifite ubukonje bwinshi, kugirango bigere ku gutatana neza.
Qingdao Sainuo Chemical Co., Ltd.Turi ababikoraIbishashara bya PE, ibishashara bya PP, ibishashara bya OPE, ibishashara bya EVA, PEMA, EBS, Zinc / Kalisiyumu Stearate.Ibicuruzwa byacu byatsinze REACH, ROHS, PAHS, FDA ikizamini.
Sainuo humura ibishashara, ikaze iperereza ryawe!
