Ibyiciro bya PP nibyiza nibyiza nibibi:
Polypropilene (PP) igabanijwemo homo-polymer polypropilene (PP-H), guhagarika (ingaruka) co-polymer polypropilene (PP-B) hamwe na polymer (polipropilen) idasanzwe (PP-R).Ni izihe nyungu, ibibi no gukoresha PP?Sangira nawe uyu munsi.
1. Homo-polymer polypropilene (PP-H)
Ihindurwa na polymerime imwe ya monomer imwe, kandi urunigi rwa molekuline ntirurimo monomer ya Ethylene, bityo ubudahwema urunigi rwa molekile ni rwinshi, kubwibyo bikoresho bifite kristu nini kandi ntigikora neza.Kugirango tunonosore ubukana bwa PP-H, bamwe mubatanga ibikoresho bibisi nabo bakoresha uburyo bwo kuvanga polyethylene na etylene-propylene reberi kugirango barusheho gukomera kwibikoresho, ariko ntibishobora gukemura byimazeyo umutekano muremure wa PP uhoraho. -H.imikorere
Ibyiza: imbaraga nziza
Ibibi: kurwanya ingaruka mbi (kurushaho gucika intege), gukomera gukomeye, guhagarara neza kurwego, gusaza byoroshye, ubukana bwigihe kirekire bwo guhangana nubushyuhe
Gushyira mu bikorwa: Urwego rwohejuru rwinshi, urwego ruringaniye, urwego rwo gutera inshinge, urwego rwa fibre, amanota ya firime.Irashobora gukoreshwa mugukenyera, kuvuza amacupa, guswera, umugozi, imifuka iboshywe, ibikinisho, ububiko, ibikoresho byamashanyarazi, ibikoresho byo murugo, agasanduku ka sasita ya microwave, agasanduku ko kubikamo, gupfunyika impapuro
Uburyo bwo kuvangura: iyo umuriro watwitse, insinga iringaniye, kandi ntabwo ari ndende.
2. Bisanzwe (random) copolymerized polypropylene (PP-R)
Iraboneka hamwe na polymerisation ya propylene monomer hamwe na monomer nkeya ya Ethylene (1-4%) munsi yubushyuhe, umuvuduko na catalizator.Ethylene monomer itangwa ku buryo butemewe kandi ikwirakwizwa mu ntera ndende ya propylene.Kwiyongera kwa Ethylene gutunguranye bigabanya kristu no gushonga kwa polymer, kandi bikanoza imikorere yibikoresho mubijyanye n'ingaruka, kurwanya hydrostatike yumuvuduko wigihe kirekire, gusaza kwa ogisijeni yumuriro muremure, no gutunganya imiyoboro no kubumba.Imiterere ya PP-R ya molekulari, ibinyabuzima bya Ethylene monomer nibindi bipimo bigira ingaruka itaziguye kumatara maremare yumuriro, imiterere yubukanishi hamwe nuburyo bwo gutunganya ibintu.Kurenza uko gukwirakwiza Ethylene monomer mumurongo wa propylene, niko guhinduka kwimiterere ya polypropilene.
Ibyiza: imikorere myiza yuzuye, imbaraga nyinshi, gukomera cyane, kurwanya ubushyuhe bwiza, guhagarara neza kurwego, gukomera kwubushyuhe buke (guhinduka neza), gukorera mu mucyo, kumurika neza
Ibibi: imikorere myiza muri PP
Gusaba: Gukuramo amanota, amanota ya firime, urwego rwo gutera inshinge.Imiyoboro, kugabanya firime, amacupa atonyanga, ibikoresho bisobanutse cyane, ibicuruzwa byo murugo bibonerana, siringi ikoreshwa, gupfunyika impapuro
Uburyo bwo kumenyekanisha: ntabwo ihinduka umukara nyuma yo gutwikwa, kandi irashobora gukuramo insinga ndende
3. Hagarika (ingaruka) co-polymer polypropilene (PP-B)
Ibigize Ethylene ni hejuru cyane, muri rusange 7-15%, ariko kubera ko amahirwe yo guhuza monomer ebyiri na monomer eshatu muri PP-B ari menshi cyane, byerekana ko kuva monomer ya ethylene ibaho gusa mugice cyo guhagarika, burigihe ya PP-H iragabanuka, ntabwo rero ishobora kugera ku ntego yo kunoza imikorere ya PP-H mubijyanye no gushonga, kurwanya hydrostatike yumuvuduko wigihe kirekire, umwuka wa ogisijeni wumuriro muremure no gutunganya imiyoboro no gukora.
Ibyiza: kurwanya ingaruka nziza, urwego runaka rwo gukomera bizamura imbaraga zingaruka
Ibibi: gukorera mu mucyo muke, ububengerane buke
Gusaba: Urwego rwo gukuramo, urwego rwo gutera inshinge.Bumpers, ibicuruzwa bikikijwe cyane, ingendo, ibikoresho bya siporo, imizigo, indobo irangi, agasanduku ka batiri, ibicuruzwa bikikijwe
Uburyo bwo kumenyekanisha: ntabwo ihinduka umukara nyuma yo gutwikwa, kandi irashobora gukuramo insinga ndende
Ingingo rusange: anti-hygroscopicity, aside na alkali irwanya ruswa, irwanya imbaraga, irwanya okiside nkeya mubushyuhe bwinshi
Igipimo cyo gutembera MFR ya PP iri murwego rwa 1-40.Ibikoresho bya PP bifite MFR nkeya bifite ingaruka nziza zo guhangana ariko guhindagurika.Kubikoresho bimwe bya MFR, imbaraga zubwoko bwa co-polymer zirenze iz'ubwoko bwa homo-polymer.Bitewe no korohereza, kugabanuka kwa PP ni hejuru cyane, muri rusange 1.8-2.5%.
