I ka hoʻohana ʻana i ka wili polypropylene fiber, ua kaupalena ʻia ka hoʻohana ʻana o ka polyethylene wax. No ka siliki denier maikaʻi maʻamau a me nā fiber kiʻekiʻe, ʻoi aku ka maikaʻi no ka hulu hipa palupalu e like me ka denier maikaʻi a me nā filament BCF kūpono no ka paving a me nā lole lole, ʻoi aku ka maikaʻi o polypropylene wax ma mua o ka polyethylene wax.

ʻO ka mea mua, ma muli o ka like ʻole ma waena o ka polypropylene a me ka polyethylene, he paʻakikī loa ka hana ʻana i ka hui like ʻana i ke ʻano microscopic, kahi e alakaʻi ai i ka hoʻokaʻawale ʻana. ʻO ka lua, no ka mea, ʻoi aku ka haʻahaʻa o ka helu heheʻe o ka polyethylene wax ma mua o ka polypropylene a i ʻole polypropylene wax, paʻakikī ke hana i nā ʻano heheʻe like ʻole o kēia mau polymers ʻelua. ʻO ka like ʻole a me ka rheology kūpono ʻole o ka huahana hiki ke alakaʻi i ka pau ʻana o ke kaʻina wili. Ma muli o kēia mau hopena ʻaoʻao, ʻoi aku ka ʻino o nā waiwai textile kino o ka fiber.
I kēia manawa, pono e hoʻohana i ka polypropylene wax me ka viscosity haʻahaʻa. Ma muli o kona viscosity haʻahaʻa a me ka pulu maikaʻi, hiki iā ia ke pulu i nā puaʻa i ka manawa pōkole. Eia kekahi, i ka wā e hohola ʻia ai ka fiber polypropylene a hoʻonoho ʻia ka wela, hiki ke ʻike ʻia mai ka mahana mālama wela (maʻamau ma kahi o 130c), ʻo ia wale nō i loko o ka pae wela o ka polyethylene wax.

Ma muli o ka hoʻololi ʻana o ka hana crystalline o ka polypropylene prima fiber, hiki ke ʻike ʻia ke kahe ʻana o ka polyethylene wax i hoʻoheheʻe ʻia mai ka polypropylene matrix a i ka ʻili fiber, ʻaʻole ia he wax maʻemaʻe wale nō, akā e lawe ʻia ka puaʻa i luna.
ʻO ka mea hope loa, ʻoi aku ka maikaʻi ma waena o ka polypropylene wax a me ka polypropylene resin ma nā ʻano micro a me macro, a he liʻiliʻi ka hopena i nā waiwai mechanical. ʻElua ʻano o ka polypropylene wax polymerized e ka metallocene catalytic technology: homopolymer polypropylene wax, a ʻo ka mea maka he propylene; ʻO ka mea ʻē aʻe he polypropylene wax copolymerized, i hana ʻia me ka propylene a me ka ethylene.
'O ka mea ma'amau, he wahi hehee ki'eki'e ka homopolymer polypropylene wax, ma waena o 140-160c, ke kaumaha mole mai nā tausani a hiki i nā 'umi tausani, pili i ka viscosity Brookfield mai nā kaukani a hiki i nā kaukani, ki'eki'e crystallinity a ki'eki'e pa'akikī. ʻO ka helu hoʻoheheʻe o ka copolymer polypropylene wax ma waena o 80-110c, ʻo ka viscosity o Brookfield he haneli i nā tausani a i ʻole ʻumi kaukani, a ʻo ke kaumaha molekala pili he mau kaukani a ʻumi tausani. Ma muli o ka hoʻohui ʻana o ka ethylene comonomer i loko o ka polypropylene copolymer, ka mea e hoʻopau i ka hoʻonohonoho maʻamau o nā molekele propylene, ua haʻahaʻa ka crystallinity o ka polypropylene copolymer, no laila ua haʻahaʻa ka helu heheʻe.

I ka hoʻomaʻamaʻa ʻana i ka puaʻa, hiki koke ka pulu viscosity haʻahaʻa, a ʻoi aku ka maikaʻi o ka pulu. Akā, pono ia i ka extrusion uea. I ka pae granulation, manaʻolana hoʻi mākou he viscosity ka wax, hiki ke hoʻololi maikaʻi i ka ikaika shear ma waena o ka puaʻa a me ka hoʻoheheʻe resin, i hiki ke hoʻohele like ʻia ka puaʻa wai i loko o ka resin hehee. I kēia manawa, hiki ke hoʻohana pū ʻia ka wax polypropylene me ka helu hoʻoheheʻe haʻahaʻa a me ka wax polypropylene me ka viscosity kiʻekiʻe e loaʻa ai ka dispersion maikaʻi loa.
Qingdao Sainuo Chemical Co., Ltd. ʻO mākou ka mea hana no ka PE wax, PP wax, OPE wax, EVA wax, PEMA, EBS, Zinc / Calcium Stearate…. Ua hala kā mākou huahana i ka REACH, ROHS, PAHS, FDA hoʻāʻo.
