Umuyoboro wo gukuramo umuyoboro wo gushyushya wa HDPE

Umuyoboro wo gukuramo umuyoboro w'ubushyuhe wa HDPE Ishusho yagaragaye

Ibisobanuro bigufi:

Umuyoboro wa PE ukingira ukoresheje PE kandi witwa umuyoboro wo kurinda inyuma wa PE, umuyoboro wa jaketi, umuyoboro wo mu maboko. Umuyoboro wa polyurethane ukingira ukoresheje ikoranabuhanga rya HDPE nk'urwego rwo kurinda inyuma, ifuro ryo hagati ryuzuyemo polyurethane rigakoreshwa nk'urwego rw'ibikoresho byo gukingira, naho urwego rw'imbere ni umuyoboro w'icyuma. Umuyoboro wa polyurethane ukingira ukoresheje ikoranabuhanga rifite imiterere myiza ya mekanike n'imikorere yo gukingira ubushyuhe. Mu bihe bisanzwe, ushobora kwihanganira ubushyuhe bwinshi bwa 120-180 °C, kandi ukwiriye imishinga itandukanye yo gukingira imiyoboro ikonje n'ishyushye mu mazi ashyushye.

Imikorere n'ibiranga

Umuyoboro w’amashanyarazi ukorwa hakoreshejwe uburyo bwihariye bwo gukingira imiyoboro ya PE, igitutu cyo gutwikira kidahindagurika, kandi ubugari bw’umuyoboro w’inkuta nto ni bumwe. Umuvuduko wo gusohora ni wihuta, umusaruro w’ubwoko bwahumetse urarushaho kuba mwiza, ubuso burabagirana, kandi imikorere y’ikoranabuhanga ni myinshi.

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.

Ibanjirije iyi: Umuyoboro muto wo gukuramo umuyoboro wa HDPE/PPR/PE-RT/PA

Ibikurikira: Umurongo wo gukuraho umuyoboro wa Silicon Coating
