Umurongo munini wo gukuramo umuyoboro wa HDPE ufite uburebure bunini

Umuyoboro wa HDPE ni ubwoko bw'umuyoboro wa pulasitiki woroshye ukoreshwa mu kohereza amazi n'umwuka, kandi ukunze gukoreshwa mu gusimbuza imiyoboro ya sima cyangwa ibyuma ishaje. Wakozwe muri HDPE yo mu bwoko bwa thermoplastic (polyethylene ifite ubucucike bwinshi), ubushobozi bwayo bwo kutavogerwa no gufatanya cyane n'imiyoboro ikomeye bituma ikoreshwa ku miyoboro ifite umuvuduko mwinshi. Umuyoboro wa HDPE ukoreshwa ku isi yose mu bikorwa nko mu miyoboro y'amazi, imiyoboro ya gazi, imiyoboro y'amazi mabi, imiyoboro yo koherezamo ibinyabiziga, kuhira mu cyaro, imiyoboro y'umuriro, imiyoboro y'amashanyarazi n'itumanaho, n'imiyoboro y'amazi y'imvura n'imiyoboro y'amazi.

Imiyoboro minini ya HDPE ifite uburebure bunini irakomeye, yoroheje, irakomeye kandi ntirwanya imiti. Irahendutse kuyishyiraho kandi imara igihe kirekire. Iyi miyoboro iboneka mu burebure busanzwe bwa metero 3, 6, 12 na 14. Imiyoboro yihariye ishobora gukorwa kugira ngo ihuze n'ibikenewe byose.

Umuyoboro wa HDPE ni umuyoboro wa pulasitiki woroshye ukozwe muri polyethylene ifite ubushyuhe bwinshi ikoreshwa cyane mu gutwara amazi n'imyanda mu bushyuhe buke. Mu bihe bya vuba aha, imiyoboro ya HDPE yakoreshejwe cyane mu gutwara amazi meza, imyanda ihumanya, imyuka itandukanye, ibitonyanga, amazi y'umuriro, amazi y'imvura, n'ibindi. Ihuriro rikomeye ry'ibikoresho by'imiyoboro ya HDPE riyifasha gukoresha mu miyoboro ifite umuvuduko mwinshi. Imiyoboro ya polyethylene ifite amateka maremare kandi akomeye yo gukorera gazi, peteroli, ubucukuzi bw'amabuye y'agaciro, amazi, n'izindi nganda. Bitewe n'uburemere bwayo buke no kudakira ingese nyinshi, inganda z'imiyoboro ya HDPE zirimo gukura cyane. Mu mwaka wa 1953, Karl Ziegler na Erhard Holzkamp bavumbuye polyethylene ifite ubushyuhe bwinshi (HDPE). Imiyoboro ya HDPE ishobora gukora neza mu bushyuhe bwinshi buri hagati ya -2200 F na +1800 F. Ariko, ikoreshwa ry'imiyoboro ya HDPE ntirisabwa iyo ubushyuhe bw'amazi burenze 1220 F (500 C).

Imiyoboro ya HDPE ikorwa hakoreshejwe polimerize ya ethylene, umusaruro w’amavuta. Inyongera zitandukanye (izituza umuriro, zuzura, pulasitiki, softeners, amavuta, ibara, ibidakoresha umuriro, ibikoresho bihuha, ibikoresho bihuza, inyongera zishobora kwangirika kuri ultraviolet, nibindi) zongerwaho kugira ngo hakorwe umuyoboro wa nyuma wa HDPE n'ibice byayo. Uburebure bw'umuyoboro wa HDPE bukorwa hakoreshejwe gushyushya resin ya HDPE. Hanyuma irasohoka binyuze mu cyuma, kigena uburebure bw'umuyoboro. Ubunini bw'urukuta rw'umuyoboro bugenwa n'uruvange rw'ingano y'icyuma, umuvuduko w'icyuma, n'umuvuduko wa traktori itwara. Ubusanzwe, umukara wa karuboni 3-5% wongerwa kuri HDPE kugira ngo idaterwa na UV, bigatuma imiyoboro ya HDPE ihinduka umukara. Hari andi mabara atandukanye ariko akenshi ntakoreshwa kenshi. Umuyoboro wa HDPE ufite ibara cyangwa imirongo akenshi uba ari 90-95% by'umukara, aho umurongo w'ibara utangwa kuri 5% by'ubuso bwo hanze.
