Umuyoboro wo gusohora umuyoboro wa HDPE wihuta cyane kandi ugabanya ingufu

Ubushakashatsi buheruka bw’ikigo cyacu n’iterambere ry’umurongo w’ingufu ukoresha ingufu wihuta, ukwiriye gusohora imiyoboro ya polyolefin yihuta. Kuzigama ingufu 35% no kongera umusaruro inshuro imwe. Imiterere yihariye ya vis ya 38-40 L/D hamwe n’agace k’umuyoboro w’ibikoresho bituma gusohora no gushyira plastike birushaho kuba byiza. Udusanduku tw’amashanyarazi dufite torque nini kandi dufite imbaraga nyinshi bitanga imikorere ihamye y’ibikoresho. Ibyuma byo gusohora n’amaboko y’ingano bikoresha imiterere igezweho cyane. Ikigega cy’amashanyarazi gikoresha PLC, traktori ifite inzira nyinshi ikoreshwa na servo, hamwe n’icyuma kidakoresha chip cyihuta bifite sisitemu yo kugenzura uburemere bwa metero. Uburemere bw’imiyoboro burushaho kuba bwiza.

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 irasohorwa 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'inyuma.
