HDPEda kuma PVC

Kayayyakin filastik suna da ƙarfi sosai kuma suna da ƙarfi. Ana iya yin su, danna ko jefa su cikin siffofi daban-daban. An yi su ne da man fetur da iskar gas. Akwai nau'ikan robobi guda biyu; thermoplastics da thermoset polymers.

Yayin da polymers na thermoset za a iya narkar da su da siffa sau ɗaya kawai kuma su kasance da ƙarfi da zarar an sanyaya su, ana iya narkar da thermoplastics da siffa akai-akai don haka ana iya sake yin amfani da su.

Ana amfani da ma'aunin zafi da sanyio don yin kwantena, kwalabe, tankunan mai, tebura da kujeru, rumfuna, jakunkuna na filastik, insulators na USB, bangarorin harsashi, kayan wasan pool, kayan kwalliya, sutura da famfo.

Akwai nau'ikan thermoplastics da yawa, kuma an rarraba su azaman amorphous ko Semi-crystalline. Biyu daga cikinsu amorphous nePVC(polyvinyl chloride) da kuma Semi-crystalline HDPE (high density polyethylene). Dukansu polymers ne na kayayyaki.

Polyvinyl chloride (PVC) polymer vinyl ne mara tsada kuma mai ɗorewa da ake amfani da shi wajen ayyukan gini. Shi ne robobi na uku da aka fi amfani da shi bayan polyethylene da polypropylene kuma ana amfani da shi sosai wajen samar da bututu. Yana da nauyi kuma mai ƙarfi, yana sa ya shahara sosai a aikace-aikacen famfo na sama da ƙasa. Yana da ƙarfi sosai kuma ya dace da binnewa kai tsaye da shigarwa mara igiya.

A daya bangaren kuma, high density polyethylene (HDPE) wani thermoplastic ne na polyethylene da aka yi daga man fetur. Yana da ƙarfi mafi girma, yana da wuya, kuma yana iya jure yanayin zafi.
HDPE bututu sun dace don amfani a cikin bututun da ke ƙarƙashin ƙasa, saboda an same su suna datsewa da ɗaukar raƙuman girgiza, don haka rage girman hawan da zai iya shafar tsarin. Hakanan suna da mafi kyawun juriya na matsawa haɗin gwiwa kuma sun fi abrasion da juriya mai zafi.

Duk da yake duka kayan suna da ƙarfi da dorewa, sun bambanta da ƙarfi da sauran fannoni. A gefe guda, an tsara su don jure matsalolin daban-daban. Don cimma matsa lamba iri ɗaya kamar bututun PVC, bangon bututun HDPE dole ne ya zama mafi kauri sau 2.5 fiye da bututun PVC.

Duk da yake ana amfani da kayan biyu don yin wasan wuta,HDPEan gano ya fi dacewa da aminci don amfani saboda yana iya kunna wutan wuta zuwa tsayin da ya dace. Idan ya kasa farawa a cikin akwati kuma ya karye, kwandon HDPE ba zai karye da karfi kamar kwandon PVC ba.

Don taƙaitawa:

1. Polyvinyl Chloride (PVC) polymer vinyl ne mara tsada kuma mai ɗorewa da ake amfani da shi wajen ayyukan gine-gine, yayin da High Density Polyethylene (HDPE) shine ma'aunin thermoplastic na polyethylene da aka yi da man fetur.
2. Polyvinyl chloride shine robobi na uku da aka fi amfani da shi, kuma polyethylene na daya daga cikin robobin da aka fi amfani da su.
3. PVC ne amorphous, yayin da HDPE ne Semi-crystalline.
4. Dukansu suna da ƙarfi da dorewa, amma tare da ƙarfin daban-daban da aikace-aikace daban-daban. PVC ya fi nauyi kuma ya fi karfi, yayin da HDPE ya fi wuya, ya fi jurewa da zafi.
5. An samo bututun HDPE don kashewa da shayar da raƙuman girgiza, don haka rage girman hawan da zai iya shafar tsarin, yayin da PVC ba zai iya ba.
6. HDPE ya fi dacewa da ƙananan shigarwar matsa lamba, yayin da PVC ya fi dacewa don binnewa kai tsaye da kuma shigarwa mara izini.
