HDPEna PVC

Ibikoresho bya pulasitiki birakomera cyane kandi birakorohera kubikora. Bishobora guhindurwa, gukanda cyangwa guterwa mu buryo butandukanye. Bikozwe ahanini muri peteroli na gaze karemano. Hari ubwoko bubiri bwa pulasitiki; thermoplastics na thermoset polymers.

Nubwo polymer za thermoset zishobora gushonga no gushushanya rimwe gusa kandi zigakomeza gukomera zimaze gukonjeshwa, thermoplastics zishobora gushonga no gushushanya inshuro nyinshi bityo zikaba zishobora kongera gukoreshwa.

Thermoplastics zikoreshwa mu gukora amakontena, amacupa, ibigega bya lisansi, ameza n'intebe zipfunyika, amazu yo kogerezamo, imifuka ya pulasitiki, insinga zikingira insinga, ibikinisho bya pisine, ibikoresho byo mu nzu, imyenda n'amazi.

Hari ubwoko butandukanye bwa thermoplastics, kandi bushyirwa mu byiciro bya amorphous cyangwa semi-crystalline. Bubiri muri bwo ntabwo buhindukaPVC(polyvinyl chloride) na semi-crystalline HDPE (polyethylene ifite ubucucike bwinshi). Byombi ni polymeri zikoreshwa mu bintu bitandukanye.

Polyvinyl chloride (PVC) ni polimeri ya vinyl ihendutse kandi iramba ikoreshwa mu mishinga y'ubwubatsi. Ni pulasitiki ya gatatu ikoreshwa cyane nyuma ya polyethylene na polypropylene kandi ikoreshwa cyane mu gukora imiyoboro. Ni yoroshye kandi ikomeye, bigatuma ikunzwe cyane mu miyoboro yo hejuru y'ubutaka no munsi y'ubutaka. Irakomeye cyane kandi ikwiriye gushyingurwa mu buryo butaziguye no gushyirwamo imiyoboro idakoresha imiyoboro.

Ku rundi ruhande, polyethylene ifite ubucucike bwinshi (HDPE) ni polyethylene thermoplastic ikozwe muri peteroli. Ifite imbaraga nyinshi, irakomeye, kandi ishobora kwihanganira ubushyuhe bwinshi.
Imiyoboro ya HDPE yoroshye gukoreshwa mu miyoboro yo munsi y'ubutaka, kuko byagaragaye ko igabanya kandi ikinjiza imiraba y'ingufu, bityo ikagabanya kwiyongera kw'imiyoboro ishobora kugira ingaruka ku buryo bw'umubiri. Ifite kandi ubushobozi bwo guhangana n'ingingo neza kandi irinda kwangirika no gushyuha.

Nubwo ibikoresho byombi bikomeye kandi biramba, biratandukanye mu mbaraga no mu bindi bintu. Ku ruhande rumwe, byagenewe kwihanganira imihangayiko itandukanye. Kugira ngo bigere ku gipimo kimwe cy'umuvuduko nk'uw'umuyoboro wa PVC, urukuta rw'umuyoboro wa HDPE rugomba kuba rufite ubunini bungana n'inshuro 2.5 ugereranije n'umuyoboro wa PVC.

Nubwo ibikoresho byombi bikoreshwa no mu gukora ibishashi by'umuriro,HDPEbyagaragaye ko ari byiza kandi bitekanye gukoreshwa kuko bishobora kurasa ibishashi by'umuriro ku burebure bukwiye. Iyo bitabashije gutangirira imbere mu gikoresho kikameneka, agakoresho ka HDPE ntikameneka n'imbaraga nyinshi nk'agakoresho ka PVC.

Muri make:

1. Polyvinyl Chloride (PVC) ni polymer ya vinyl ihendutse kandi iramba ikoreshwa mu mishinga y'ubwubatsi, mu gihe Polyethylene ifite ubucucike bwinshi (HDPE) ari thermoplastic ya polyethylene ikozwe muri peteroli.
2. Polyvinyl chloride niyo ikoreshwa cyane muri plastiki, naho polyethylene ni imwe muri plastiki zikoreshwa cyane.
3. PVC nta shusho igaragara, mu gihe HDPE ari semi-crystalline.
4. Byombi birakomeye kandi biraramba, ariko bifite imbaraga zitandukanye kandi bifite ikoreshwa ritandukanye. PVC iraremereye kandi ikomeye, mu gihe HDPE ikomeye, irinda kwangirika no kwihanganira ubushyuhe.
5. Imiyoboro ya HDPE yagaragaye ko igabanya kandi ikinjiza imiraba y'amashanyarazi, bityo ikagabanya kwiyongera kw'amazi bishobora kugira ingaruka ku buryo bw'imikorere, mu gihe PVC yo idashobora.
6. HDPE ikwiriye cyane gushyirwaho umuvuduko muto, mu gihe PVC ikwiriye cyane gushyirwaho mu buryo butaziguye no mu buryo butarimo imiyoboro.
