Ka hopena o ka hoʻohui CPE ma PVC

1、 ʻEkolu mau mea nui e pili ana i ka hana CPE
ʻO ka mea mua, ʻo ia ke ʻano o CPE i hoʻohana ʻia.Loaʻa ka CPE mai ka polyethylene kaumaha kiʻekiʻe i ka viscosity kiʻekiʻe a me ka ikaika tensile, akā haʻahaʻa ka adhesion ma waena o kēia CPE a me PVC resin.ʻO ka CPE i loaʻa mai ka polyethylene kaumaha haʻahaʻa he haʻahaʻa viscosity a me ka ikaika tensile, a ʻo CPE i loaʻa mai ka polyethylene kiʻekiʻe kiʻekiʻe he maikaʻi ka wela.
ʻO ka lua, ʻo ia ka nui o nā ʻāpana maka.Ke liʻiliʻi ka nui o ka ʻāpana, maʻalahi ka hana ʻana i ka jelly a i ʻole clumpy CPE, a i ka nui o ka nui o ka ʻāpana, ʻaʻole like ka māhele ʻana o ka chlorine.
Eia hou, ʻo ia ka pae o ka CPE chlorination.Ke emi iho ka chlorine ma lalo o 25%, ʻaʻole hiki ke hoʻohana ʻia me ka PVC.Ke ʻoi aku ka nui o ka chlorine ma mua o 40%, hiki ke hoʻopili maikaʻi ʻia me PVC a hiki ke hoʻohana ʻia e like me ka plasticizer paʻa, ʻaʻole kūpono e like me ka hoʻololi ʻana i ka hopena;ʻO CPE me kahi chlorine maʻiʻo o 36-38% he elasticity maikaʻi a me ka hoʻohālikelike ʻana me PVC, e hoʻohana nui ʻia e like me ka hoʻololi ʻana i ka hopena no PVC.I kēia manawa, hoʻohana mau ʻia ka CPE me kahi chlorine content o 35%.CPE me ka chlorine maʻiʻo o ma kahi o 35% he haʻahaʻa crystallinity a me ke aniani hoʻololi wela, maikaʻi lāʻau elasticity, a kūpono kūpono me PVC.Hoʻohana nui ia e like me ka hoʻololi ʻana i ka hopena no nā huahana paʻakikī PVC.
2、 Ka hopena o ka hoʻohui CPE ma PVC
Ke emi ka nui o ka hoʻohui ʻana ma lalo o 10 mau minuke, piʻi wikiwiki ka ikaika o ka hopena o PVC me ka hoʻohui ʻana o CPE, akā e hoʻonui hou aʻe i ka nui o ka hoʻohui ʻana o ka CPE i ka hopena liʻiliʻi i ka ikaika hopena o PVC.No laila, ma ke ʻano he mea kū i ka hopena, ʻo ka nui kūpono o ka CPE e hoʻohui ʻia he 8-10 mau ʻāpana.Ke piʻi aʻe nei ka CPE, e emi ana ka ikaika tensile o nā hui PVC, ʻoiai ke piʻi nei ka elongation i ka wā hoʻomaha.Inā hōʻike ʻia ka paʻakikī e like me ka huahana o ka ikaika tensile a me ka elongation i ka wā haʻihaʻi, ʻike ʻia e piʻi nui ka paʻakikī o PVC me ka piʻi ʻana o ka hoʻohui CPE.
