Ibikoresho bya PP ni iki? Isesengura ryuzuye ryimiterere, porogaramu nibyiza byibikoresho bya PP
Mu rwego rwa chimique nibikoresho, "PP niki" nikibazo gikunze kugaragara, PP ni impfunyapfunyo ya Polypropilene, ni polymer ikoreshwa cyane. Muri iyi ngingo, tuzasesengura birambuye imiterere, inzira yumusaruro, aho usaba inyungu nibyiza byibikoresho bya PP kugirango dusubize ikibazo cyibibazo PP.
1. PP ni iki? Ibanze shingiro nimiterere
Ibikoresho bya PP, ni ukuvuga polypropilene, ni thermoplastique ikozwe muri propylene monomer binyuze muri polymerisation reaction. Ifite umurongo ugizwe, uyiha kuringaniza gukomera no gukomera mumiterere yabyo kubera imiterere yihariye ya molekile. Polypropilene ifite ubucucike buke bwa 0,90 g / cm³ gusa, bigatuma iba imwe muri plastiki yoroshye, umutungo utuma biba byiza mubikorwa byinshi.
Polipropilene irwanya imiti cyane, irwanya aside nyinshi, ibishingwe, umunyu hamwe nudukoko twinshi. Ahantu ho gushonga cyane (hafi 130-170 ° C) itanga ibikoresho bya PP bihamye neza mubushyuhe bwo hejuru kandi bigatuma badakunda guhinduka. Kubwibyo, ibikoresho bya PP bikoreshwa cyane mubihe bisaba ubushyuhe no kurwanya ruswa.
2. Uburyo bwo gukora ibikoresho bya PP
Umusaruro wibikoresho bya PP ahanini ushingiye kubuhanga bwa catalizator hamwe na polymerisation. Uburyo busanzwe bwo gukora polypropilene burimo gaz-feri polymerisation, polymerisation ya feri-feri na polymerisation yimbere. Uburyo butandukanye bwa polymerisation bugira ingaruka kuburemere bwa molekuline, kristalline hamwe nibintu bifatika byibikoresho bya PP, nabyo bikagena aho bakoreshwa.
Ubwoko butandukanye bwa polypropilene, nka polopropilene ya homopolymerised (Homo-PP) na polypropilene ya copolymerised (Copo-PP), irashobora kuboneka muguhindura ubwoko bwa catalizator hamwe nuburyo ibintu byifashe mugihe cyo gukora. Homopolymerised polypropylene ifite ubukana bwinshi kandi irwanya ubushyuhe, mugihe polypropilene ya cololymerised ikunze kugaragara mugukoresha burimunsi kubera imbaraga zayo nyinshi.
3. Ibice byingenzi bisabwa kubikoresho bya PP
Ibikoresho bya PP bikoreshwa mu nganda zitandukanye bitewe nuburyo bwiza bwumubiri nubumara. Mubuzima bwa buri munsi, PP ikoreshwa mugukora ibikoresho byo murugo, gupakira ibiryo, imiyoboro n ibikinisho, nibindi. Mu nganda, PP ikoreshwa cyane mugukora imiyoboro yimiti, pompe na valve, nibindi. Ibikoresho bya PP nabyo bikoreshwa cyane mugukora imyenda, ibikoresho byubuvuzi nibice byimodoka.
By'umwihariko mu nganda zipakira, PP yahindutse ibikoresho byatoranijwe kubera gukorera mu mucyo no kurwanya ubushyuhe, nk'isanduku isanzwe ibika ibiryo mu mucyo, ibikoresho byo mu ziko rya microwave, n'ibindi.
4. Ibyiza bya PP nibyiza byamasoko
Ibikoresho bya PP bitoneshwa cyane cyane kubera uburemere bwabyo, kurwanya ubushyuhe, kurwanya imiti no gutunganya neza.PP ifite kandi amashanyarazi meza cyane hamwe no kurengera ibidukikije, irashobora gukoreshwa kugirango igabanye ibidukikije.
Urebye ku isoko, hamwe n’igitekerezo cy’iterambere rirambye no kurengera ibidukikije bibisi, isoko ry’ibikoresho bya PP riziyongera. Imyunyungugu ya Polypropilene hamwe n’ibiranga imyuka ihumanya ikirere bituma irushaho kuba ingirakamaro mu bikorwa bitandukanye bigenda bigaragara, nk’isoko rishya ry’ingufu n’ibikoresho bitangiza ibidukikije.
5. Ibibi n'ibibazo by'ibikoresho bya PP
Nubwo ibyiza byayo bigaragara, PP ifite ibitagenda neza, nko kutagira ubushyuhe buke bwo guhangana nubushyuhe buke no kurwanya urumuri UV. Mubikorwa bifatika, izi nenge zirashobora kunozwa muguhuza guhindura, kongeramo antioxydants hamwe ninyongeramusaruro ya UV. Hamwe niterambere ryikoranabuhanga, ubushakashatsi niterambere rya bio-ishingiye kuri polypropilene na copolymer ikora cyane nabyo birakomeje, byugurura uburyo bushya bwo gukoresha ibikoresho bya polypropilene.
Umwanzuro
PP ni iki? Ni thermoplastique hamwe nibintu byiza cyane hamwe nurwego runini rwa porogaramu. Binyuze mu isesengura rirambuye ku miterere yacyo, inzira zibyara umusaruro, aho zikoreshwa hamwe n’isoko ry’isoko, dushobora kubona umwanya udasimburwa wibikoresho bya PP mu nganda zitandukanye. Hamwe niterambere ryikoranabuhanga hamwe no kurengera ibidukikije bikenewe, urugero rwibikoresho bya PP ruzakomeza kwaguka, bizana ibyoroshye no guhanga udushya mu nganda nubuzima bugezweho.
Turizera ko ukoresheje isesengura rirambuye ryiyi ngingo, urumva neza icyo PP ari ibikoresho.
