PE okun ohun elo

PE jẹ apopọ polyethylene kan, ni akọkọ pin si polyethylene iwuwo giga (HDPE), polyethylene iwuwo alabọde (MDPE), polyethylene iwuwo kekere (LDPE) ati polyethylene iwuwo kekere laini (LLDPE).

    1.HDPE jẹ iru crystallinity giga, resini thermoplastic ti kii-pola ti a ṣe nipasẹ ethylene copolymerization. Irisi HDPE atilẹba jẹ funfun wara, ati pe o jẹ translucent si iwọn kan ni apakan ti o kere. O ni resistance ti o dara julọ si ọpọlọpọ awọn kemikali ile ati ti ile-iṣẹ, ati pe o le koju ipata ati itusilẹ ti awọn oxidants ti o lagbara (acid nitric ogidi), acid ati awọn iyọ alkali ati awọn nkan ti o nfo Organic (erogba tetrachloride). Awọn polima ko ni fa ọrinrin ati ki o ni o dara omi resistance to nya, eyi ti o le ṣee lo fun ọrinrin ati seepage Idaabobo.
    2.MDPE ti wa ni ipo nipasẹ idaamu idaamu ayika ati idaduro agbara igba pipẹ. Awọn iwuwo ibatan ti MDPE jẹ 0.926-0.953, crystallinity jẹ 70% -80%, apapọ iwuwo molikula jẹ 200,000, agbara fifẹ jẹ 8-24 mpa, elongation ni isinmi jẹ 50% -60%, iwọn otutu yo jẹ 126-135 ℃, ati awọn yo sisan oṣuwọn jẹ 0.1-35 g /10 iṣẹju. Awọn iwọn otutu abuku gbona (0.46 mpa) 49-74 ℃.
    3. Kekere iwuwo polyethylene ni awọn lightest orisirisi ni polyethylene resini. Ti a ṣe afiwe pẹlu polyethylene iwuwo giga, crystallinity rẹ (55% -65%) ati aaye rirọ (90-100 ℃) jẹ kekere. O ni o ni ti o dara softness, extensibility, akoyawo, tutu resistance ati processability. Iduroṣinṣin kemikali rẹ dara, o le duro fun acid, alkali ati iyọ olomi ojutu; Idabobo itanna to dara ati permeability gaasi; Gbigba omi kekere; Rọrun lati sun. Ohun-ini jẹ rirọ, pẹlu extensibility ti o dara, idabobo itanna, iduroṣinṣin kemikali, iṣẹ ṣiṣe ati resistance iwọn otutu kekere (resistance si -70 ℃).
    4. Akawe pẹlu LDPE, LLDPE ni o ni awọn anfani ti ga agbara, ti o dara toughness, lagbara rigidity, ooru resistance, tutu resistance, etc.LLDPE tun ni o dara ayika wahala wo inu resistance, yiya resistance ati awọn miiran-ini, ati ki o le koju acid, alkali, Organic epo ati be be lo.
    Akiyesi: Awọn patikulu ṣiṣu PE ni lilo pupọ ati pe o nilo lati ṣe adani ni ibamu si awọn ibeere alabara ni awọn oju iṣẹlẹ oriṣiriṣi.
