Ni awọn ohun elo ti polypropylene okun alayipo, awọn ohun elo tiepo-eti polyethyleneni opin.Fun awọn filamenti denier itanran lasan ati awọn okun didara giga, paapaa fun irun rirọ bi denier itanran ati awọn filaments BCF ti o dara fun paving ati awọn aso aṣọ, epo-eti polypropylene nigbagbogbo dara julọ si epo-eti polyethylene.
Sainuo ga-ti nwepo-eti polypropylene, dede iki, ga yo ojuami, ti o dara lubricity, ati ti o dara dispersibility.Lọwọlọwọ o jẹ oluranlọwọ ti o tayọ fun sisẹ polyolefin, resistance otutu otutu, ati adaṣe giga.

Ni akọkọ, nitori aiṣedeede laarin polypropylene ati polyethylene, o ṣoro pupọ lati dagba idapọ aṣọ ni oye micro, eyiti yoo yorisi ipinya alakoso.
Ẹlẹẹkeji, nitori awọn yo ojuami ti polyethylene epo jẹ significantly kekere ju ti polypropylene tabi polypropylene epo, o jẹ soro lati wo pẹlu awọn ti o yatọ yo abuda ti awọn meji polima.Aidọgba ati rheology ti ko yẹ ti ọja le ja si opin fifọ ti ilana yiyi.Nitori awọn ipa ẹgbẹ wọnyi, awọn ohun-ini asọ ti ara ti okun di buru.
Ni akoko yii, o jẹ dandan lati lo epo-eti polypropylene pẹlu iki kekere.Nitori iki kekere rẹ ati omi tutu to dara, o le tutu pigmenti ni igba diẹ.Ni afikun, nigba yiya ati ooru ṣeto okun polypropylene, o le rii lati iwọn otutu itọju ooru (nigbagbogbo nipa 130c), eyiti o kan laarin iwọn otutu yo ti epo-eti polyethylene.
Nitori iyipada ti ọna okuta ti okun akọkọ ti polypropylene, o le ṣe akiyesi pe epo-eti polyethylene didà sinu oju okun lati inu polypropylene matrix, ati kii ṣe epo-eti mimọ nikan, ṣugbọn awọ tun yoo mu wa si dada.

Ni ipari, ibaramu laarin epo-eti polypropylene ati resini polypropylene dara ni awọn aaye micro ati macro, ati pe o ni ipa diẹ lori awọn ohun-ini ẹrọ.Awọn iru meji ti epo-eti polypropylene polima ni o wa nipasẹ imọ-ẹrọ catalytic metallocene: ọkan jẹ epo-eti polypropylene homopoly, ati ohun elo aise jẹ propylene;Ekeji jẹ epo-eti polypropylene copolymerized, eyiti o nlo propylene ati ethylene bi awọn ohun elo aise.
Ni gbogbogbo, epo-eti homopolypropylene ni aaye yo giga laarin 140-160c, iwuwo molikula lati ẹgbẹẹgbẹrun si ẹgbẹẹgbẹrun, ti o baamu iki Brookfield lati awọn dosinni si ọpọlọpọ gbigbẹ, kristali giga ati lile lile.Aaye yo ti epo-eti polypropylene copolymerized nigbagbogbo laarin 80-110 ℃, iki ti Brookfield jẹ ọgọọgọrun si ẹgbẹẹgbẹrun tabi paapaa ẹgbẹẹgbẹrun, ati iwuwo molikula ti o baamu jẹ ẹgbẹẹgbẹrun si ẹgbẹẹgbẹrun.Nitori afikun ethylene comonomer ni polypropylene copolymerized, eyiti o fa idamu iṣeto deede ti awọn ohun elo propylene, crystallinity ti polypropylene copolymerized jẹ kekere ati aaye yo kan pato tun jẹ kekere.
Ni ipele idọti pigmenti, ifasilẹ epo-eti kekere viscosity waye ni kiakia ati ṣiṣe ṣiṣe ti o ga julọ.Ṣugbọn o nilo ni extrusion waya.Ni ipele granulation, a nireti pe epo-eti naa ni iki kan, eyiti o le gbe agbara rirẹ daradara laarin pigmenti ati yo resini, ki awọ tutu le pin kaakiri ni yo resini.Ni akoko yii, o le ṣe akiyesi lati lo epo-eti polypropylene pẹlu aaye yo kekere ati epo-eti polypropylene pẹlu iki giga, ki o le ṣe aṣeyọri pipinka ti o dara julọ.
Qingdao Sainuo Chemical Co., Ltd.A ni o wa olupese funepo-eti PE, epo-eti PP, epo-eti OPE, EVA epo-eti, PEMA, EBS, Zinc/ Calcium Stearate….Awọn ọja wa ti kọja REACH, ROHS, PAHS, idanwo FDA.
