HDPEna PVC

Ibikoresho bya plastiki biroroshye cyane kandi byoroshye. Birashobora kubumbabumbwa, gukanda cyangwa gutabwa muburyo butandukanye. Zigizwe ahanini na peteroli na gaze gasanzwe. Hariho ubwoko bubiri bwa plastiki; thermoplastique hamwe na polimeri ya thermoset.

Mugihe polimeri ya termoset ishobora gushonga gusa hanyuma igakorwa rimwe hanyuma igakomeza gukomera iyo imaze gukonjeshwa, thermoplastique irashobora gushonga no gushirwaho inshuro nyinshi bityo ikaba ishobora gukoreshwa.

Thermoplastique ikoreshwa mugukora kontineri, amacupa, ibigega bya lisansi, kumeza hamwe nintebe, isuka, imifuka ya pulasitike, insulator zikoresha insinga, imbaho ​​zitagira amasasu, ibikinisho bya pisine, ibikoresho, imyenda hamwe n’amazi.

Hariho ubwoko bwinshi bwa thermoplastique, kandi byashyizwe mubikorwa nka amorphous cyangwa semi-crystalline. Babiri muri bo ni amorphousPVC(polyvinyl chloride) na kimwe cya kabiri cya kristaline HDPE (polyethylene yuzuye). Byombi ni ibicuruzwa bya polimeri.

Polyvinyl chloride (PVC) ni vinyl polymer ihendutse kandi iramba ikoreshwa mumishinga yubwubatsi. Nibintu bya gatatu bikoreshwa cyane nyuma ya polyethylene na polypropilene kandi bikoreshwa cyane mugukora imiyoboro. Nibyoroshye kandi birakomeye, bituma bikundwa cyane mubutaka-bwubutaka no munsi yubutaka. Birakomeye cyane kandi birakwiriye gushyingurwa bitaziguye no kwishyiriraho imiyoboro.

Kurundi ruhande, polyethylene yuzuye (HDPE) ni polyethylene thermoplastique ikozwe muri peteroli. Ifite imbaraga zisumba izindi, irakomeye, kandi irashobora kwihanganira ubushyuhe bwinshi.
Imiyoboro ya HDPE iroroshye gukoreshwa mu miyoboro yo munsi y'ubutaka, kuko wasangaga igabanya kandi ikurura imivumba yo guhungabana, bityo bikagabanya umuvuduko ushobora kugira ingaruka kuri sisitemu. Bafite kandi uburyo bwiza bwo guhunika hamwe kandi birwanya cyane kandi birwanya ubushyuhe.

Mugihe ibikoresho byombi bikomeye kandi biramba, biratandukanye mumbaraga nibindi. Ku ruhande rumwe, zagenewe guhangana n'imihangayiko itandukanye. Kugirango ugere ku gipimo kimwe n’umuyoboro wa PVC, urukuta rwa HDPE rugomba kuba rufite umubyimba wikubye inshuro 2,5 umuyoboro wa PVC.

Mugihe ibikoresho byombi nabyo bikoreshwa mugukora fireworks,HDPEbyagaragaye ko bikwiriye kandi bifite umutekano kubikoresha kuko birashobora kurasa fireworks muburebure bukwiye. Niba binaniwe gutangira imbere muri kontineri ikavunika, kontineri ya HDPE ntizacika n'imbaraga nyinshi nka kontineri ya PVC.

Mu ncamake:

1.
2. Polyvinyl chloride ni iya gatatu ikoreshwa cyane muri plastiki, kandi polyethylene ni imwe muri plastiki zikoreshwa cyane.
3. PVC ni amorphous, mugihe HDPE ari kimwe cya kabiri.
4. Byombi birakomeye kandi biramba, ariko hamwe nimbaraga zitandukanye nibikorwa bitandukanye. PVC iraremereye kandi ikomeye, mugihe HDPE irakomeye, irwanya abrasion kandi irwanya ubushyuhe bwinshi.
5. Imiyoboro ya HDPE yabonetse kugirango ihagarike kandi ikureho imivurungano, bityo bigabanye umuvuduko ushobora kugira ingaruka kuri sisitemu, mugihe PVC idashobora.
