Vuga muri make ibintu nyamukuru n'imikoreshereze ya plastiki ya PP

Vugana nawe kubintu nyamukuru nimikoreshereze ya polypropilene (PP).

Mbere ya byose, polypropilene ni iki?Polypropilene mu magambo ahinnye yitwa "PP".Nibikoresho bya termoplastique hamwe nibisanzwe kandi birebireUMUKINNYI W'AMATORA(kristalline igera kuri 95%) polymerized kuva propylene.Irashobora kugabanywa muburyo bwo gutera inshinge za PP, gushushanya insinga za PP, fibre ya PP, firime ya PP, umuyoboro wa PP.Muri plastiki zikunze gukoreshwa mubuzima, polypropilene ni bumwe mu bwoko bworoshye.

Hano haribintu bya polypropilene:

1. Imiterere yumubiri: idafite uburozi, impumuro nziza, uburyohe, amata yera kandi yuzuye ya hrstalline yuzuye 0.9-0.91g / cm3 gusa, umutekano mwiza kumazi.

2. Imikorere yubushyuhe: Ifite ubushyuhe bwiza, kandi ibicuruzwa byayo birashobora guhindagurika mubushyuhe buri hejuru ya 100 ° C, kandi ntibizahinduka kuri 150 ° C nta mbaraga zituruka hanze.Ubushyuhe bwo gutwika ni -35 ° C, kandi kwinjiza bibaho munsi ya -35 ° C, kandi kurwanya ubukonje ntabwo ari byiza nka polyethylene.

3. Imiti ihamye: Imiti ihamye ni nziza cyane.Usibye kwangirika na acide sulfurike hamwe na acide ya nitricike yibanze, irahagaze neza kubindi bikoresho bya chimique, ariko hydrocarbone ya hydrocarbone yuburemere bwa molekile nkeya, hydrocarbone ya aromatic na hydrocarbone ya chlorine irashobora gutuma polymer Propylene yoroha ikabyimba, kandi imiti ikomeza kwiyongera hamwe kwiyongera kwa kristu, polypropilene rero ikwiriye gukora imiyoboro itandukanye ya chimique na fitingi, kandi ifite ingaruka nziza zo kurwanya ruswa.

4. Ibikoresho by'amashanyarazi: Ifite coefficente ya dielectricike, kandi hamwe no kuzamuka kwubushyuhe, irashobora gukoreshwa mugukora ibicuruzwa bishyushye byamashanyarazi.Ifite kandi imbaraga nyinshi zo kumeneka kandi ikwiriye gukoreshwa nkibikoresho byamashanyarazi, nibindi. Ifite imbaraga zo guhangana na voltage na arc, ariko ifite amashanyarazi ahamye, kandi biroroshye gusaza iyo ihuye numuringa.

Polypropilene ikoreshwa cyane mubikoresho byo murugo hamwe nu miyoboro ya pulasitike.Ibikoresho byo murugo byateye imbere byihuse mumyaka yashize, hamwe nubwoko bwinshi nibisohoka byinshi.Kubwibyo, mumyaka mike iri imbere, iterambere ryibikoresho bidasanzwe bya PP kubikoresho byo murugo bizongerwa kugirango isoko rihinduke.

Mu 2003, umusaruro rusange w’imiyoboro ya pulasitike warenze toni miliyoni 1.8, umwaka ushize wiyongereyeho 23%.Mu minsi ya mbere, imiyoboro ya PP yakoreshwaga cyane cyane nk'imiyoboro y'amazi y'ubuhinzi, ariko isoko ntiyashoboye gukingurwa kubera ibibazo bimwe na bimwe byakozwe mu mikorere y'ibicuruzwa byambere (imbaraga zingaruka no kurwanya gusaza).Ariko hamwe no gutangiza ikoranabuhanga, isoko ryamenyekanye buhoro buhoro.Imiyoboro ya plastike ni kimwe mu bicuruzwa by'ingenzi bigamije kumenyekanisha no gukoresha ibikoresho byubaka imiti mu gihugu cyanjye.Minisiteri y’ubwubatsi yasohoye “Itangazo ryo gushimangira imicungire y’umusaruro no guteza imbere no gukoresha imiyoboro ya Copolymerized Polypropylene (PP-R, PP-B)” mu 2001, isaba inzego zibishinzwe Gukorera hamwe gukora akazi keza k’ibikoresho fatizo, gutunganya, ubuziranenge bwo gukoresha imiyoboro nogushiraho, no kugenzura neza ubuziranenge bwimiyoboro ya PP, kugirango turusheho gukora akazi keza mugukora, gukoresha no kuzamura imiyoboro ya PP mugihugu cyanjye.

Hamwe no kuzamura imibereho yabantu, ni inzira nziza yiterambere mugutezimbere ibikoresho byihariye bya PP bisobanutse, cyane cyane ibikoresho bya PP bifite umucyo mwinshi, amazi meza, hamwe nuburyo bwihuse birasabwa gushushanya no gutunganya mubicuruzwa PP bakunda.PP isobanutse iranga PP isanzwe, PVC, PET, PS, kandi ifite ibyiza byinshi hamwe niterambere ryiterambere.Kugeza ubu, hari itandukaniro rinini hagati y’ibikoresho byihariye bya PP byo mu gihugu n’ibihugu by’amahanga, kandi umusaruro no gushyira mu bikorwa ibicuruzwa bya PP bisobanutse n’ibicuruzwa byayo biracyakenewe gushimangirwa.

Mubyongeyeho, polypropilene nayo ikoreshwa mukurambura firime ya PP nibindi.
