He aha nā kumu o ka hoʻohana nui ʻana o ka polypropylene i ka ʻenehana hoʻoheheʻe ʻia?

ʻO ke kumu hana o ka lole meltblown

ʻO ka lole Meltblown kahi mea e hoʻoheheʻe ai i nā polymers i nā wela kiʻekiʻe a laila e pīpī iā lākou i loko o nā fiber ma lalo o ke kaomi kiʻekiʻe. Hoʻomaʻalili wikiwiki kēia mau fibers a paʻa i ka lewa, e hana ana i kahi pūnaewele fiber kiʻekiʻe, kiʻekiʻe. ʻAʻole maikaʻi wale ka hana kānana ʻana o kēia mea, akā he māmā a me ka hanu, e kūpono loa ia no ka hoʻohana ʻana i nā mea pale e like me nā masks.

ʻO nā mea maka nui no nā lole meltblown

ʻO ka mea nui no ka lole meltblown he polypropylene, i kapa ʻia ʻo PP material. I kēia manawa, hoʻohana nā masks meltblown maʻamau ma ka mākeke i ka polypropylene meltblown fabric ma ke ʻano he kānana. ʻO ke kumu o ke koho ʻana i ka polypropylene ma ke ʻano he kumu waiwai nui, ʻo ia ka maikaʻi o ka hana ʻana i ka hana a me nā uku kumukūʻai, a he mea pili i ke kaiapuni.

Ma waho aʻe o ka polypropylene, hiki ke hana ʻia nā lole meltblown me nā mea ʻē aʻe e like me ka polyester, nylon, ke olonā, a me nā mea ʻē aʻe.

Hoʻohana nui ʻia ʻo Polypropylene i ka ʻenehana hoʻoheheʻe ʻia no ka mea he mau pono kēia

1. Hiki ke ho'omalu 'ia ka viscosity o ka polymer ma o ka ho'ohana 'ana i ka oxidants a i 'ole ka peroxides i loko o ke ka'ina extrusion, a i 'ole ma ka mechanical shearing the extruder a i 'ole ka ho'omalu 'ana i ka mahana hana no ka loa'a 'ana o ka wela wela, i mea e ho'oponopono ai i ka viscosity o ka hehe'e.

2. Hiki ke ho'omalu 'ia ka pu'unaue kaumaha mole e ka ho'ohehe'e 'ana i ka lole lole 'ole i ulana'ia, e koi ana i ka pu'unaue kaumaha molekala haiki i mea e hana 'ia ai ka lole ultrafine like 'ole. Ma ka hoʻohana ʻana i nā ʻenehana catalytic hou e like me ka metallocene catalysts, hiki ke hana ʻia nā polymers me ka helu hoʻoheheʻe kiʻekiʻe loa a me ka hāʻawi ʻana i ke kaumaha molekala haiki.

3. ʻO kahi mea hoʻoheheʻe kiʻekiʻe ua lawa ia no ka pale ʻana i ka wela o ka polypropylene no ka hapa nui o nā noi huahana, a he ākea ākea o ka propylene hehee. No laila, ʻoi aku ka maikaʻi o ka Scope no ka hana maʻamau i hoʻohana ʻia i ka hoʻopaʻa ʻana i ka wela i ka ʻenehana lole ʻaʻole i ulana ʻia.

4. He mea maikaʻi ke hana i nā fibers ultrafine. Inā haʻahaʻa ka viscosity o ka polypropylene melt a haiki ka puʻunaue molecular weight, hiki ke hana ʻia i mau fibers maikaʻi loa ma lalo o ka hoʻohana ʻana i ka ikehu like a me nā kūlana hoʻolōʻihi i ke kaʻina hoʻoheheʻe. No laila, ʻo ke anawaena fiber maʻamau o ka polypropylene melt blown non-woven fabric he 2-5um, a ʻoi aku ka maikaʻi.

5. Ma muli o ka hoʻohana ʻana i ke kiʻi kiʻekiʻe o ka ea wela i ke kaʻina hana hoʻoheheʻe ʻana, pono ia e hoʻohana i nā polymers me ka helu hoʻoheheʻe kiʻekiʻe, kahi mea e pono ai no ka hoʻonui ʻana i ka hana a me ka hoʻemi ʻana i ka ikehu. I kēia manawa, ʻo ka nui o ka polypropylene chips i hoʻoheheʻe ʻia he 400-1200g / 10min a me ka hāʻawi ʻana i ke kaumaha molecular liʻiliʻi e hana i nā fibers ultrafine me ka pono linear density.

6. Pono nā ʻāpana polypropylene i hoʻohana ʻia i ka hoʻoheheʻe ʻana i ka hoʻoheheʻe ʻana a me ka hoʻoili ʻana i ka helu helu heheʻe kiʻekiʻe a kūlike, ka hāʻawi ʻana i ke kaumaha molecular haiki, nā hiʻohiʻona hoʻoheheʻe hoʻoheheʻe maikaʻi maikaʻi, a me ka maikaʻi a me ka paʻa paʻa e hōʻoia i ke kaʻina hana o nā mea i ulana ʻole ʻia.

ʻO ka mālama ʻana no ka hana ʻana i ka lole meltblown

I ka hana ʻana i ka lole meltblown, pono e hoʻomaopopo ʻia kēia mau mea:

1. Pono pono ka ma'ema'e o ka mea i koho 'ia: E like me ka mea e pono ai ka lole meltblown e ho'okō i ka hopena kānana, pono e koho i nā mea i ma'ema'e ma ke koho 'ana i nā mea maka. Inā he nui nā mea haumia, e hoʻopilikia ia i ka pono kānana o ka lole meltblown.

2. E hoʻomalu i ka mahana hana a me ke kaomi: Pono e hoʻonohonoho ʻia ka mahana hana a me ke kaomi e like me ke ʻano o ka mea maka e hōʻoia i ka pono o ka hana ʻana o ka fiber.

3. E hōʻoia i ka hoʻomaʻemaʻe i loko o ke kaiapuni hana: E like me ka hoʻohana ʻia ʻana o ka lole meltblown no ka hana ʻana i nā mea pale e like me nā masks, he mea nui ka hoʻomaʻemaʻe ʻana i ka ʻenehana hana. Pono e hōʻoia i ka maʻemaʻe o ka hale hana hana e pale ai i ka hoʻohaumia ʻana i nā huahana.

Dongguan Liansheng Non ulana 'enehana Co., Ltd.ua hoʻokumu ʻia ma Mei 2020. He ʻoihana hana lole lole ʻaʻole i ulana nui ʻia e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, a me ke kūʻai aku. Hiki iā ia ke hana i nā kala like ʻole o ka PP spunbond non-woven fabrics me ka laulā o lalo o 3.2 mika mai 9 grams a 300 grams.
