Ka lole spunbond pp unwoven hiki ke hanu

ʻO nā hiʻohiʻona o ka lole spunbond pp nonwoven

1. ʻO ka PP spunbond non-woven fabric nā hiʻohiʻona o ka pale wai, ka hanu, ka maʻalahi, ʻaʻole hiki ke puhi, ʻaʻohe mea ʻawaʻawa a ʻaʻole hoʻonāukiuki, a me nā kala momona. Inā waiho ʻia ka mea i waho a hoʻoheheʻe maoli ʻia, ʻo 90 lā wale nō kona ola. Inā waiho ʻia i loko o ka hale a hoʻoheheʻe ʻia i loko o 5 mau makahiki, ʻaʻohe mea ʻawaʻawa, ʻaʻohe ʻala, ʻaʻohe koena mea i ke ahi, no laila ʻaʻole ia e hoʻohaumia i ke kaiapuni. No laila, loaʻa mai ka mālama kaiapuni mai kēia.

2. ʻO ka lole PP non-woven i nā hiʻohiʻona o ke kahe kaʻina hana pōkole, ka wikiwiki hana wikiwiki, ka hua kiʻekiʻe, ke kumu kūʻai haʻahaʻa, ka hoʻohana ākea, a me nā kumu waiwai maka.

Ka hoʻomohala ʻana o ka lole ʻaʻole i ulana ʻia ʻo Spunbond pp

Ua ulu wikiwiki ka PP non-woven fabric ma Kina, e hoʻokō ana i ka ulu wikiwiki o ka hana a me ke kūʻai aku, akā aia kekahi mau pilikia i ka wā o ka hoʻomohala ʻana. ʻO nā kumu o nā pilikia e like me ka haʻahaʻa haʻahaʻa mechanization a me ka lohi o ka ʻoihana ʻoihana he multifaceted. Ma waho aʻe o nā mea e like me ka ʻōnaehana hoʻokele a me ke kūʻai aku ʻana, ʻo ka ikaika ʻenehana nāwaliwali a me ka nele o ka noiʻi kumu ka mea nui. ʻOiai ua hōʻiliʻili ʻia kekahi ʻike hana i nā makahiki i hala iho nei, ʻaʻole ia i manaʻo ʻia a paʻakikī ke alakaʻi i ka hana mechanized.

He aha ke kūpaʻa kemika o ka lole spunbond pp nonwoven

1. Hana kino

ʻO ka lole spunbond non-woven PP he mea ʻawaʻawa a me ka ʻala ʻole keʻokeʻo keʻokeʻo kiʻekiʻe crystalline polymer, ʻo ia kekahi o nā ʻano māmā loa o nā plastics. Paʻa loa ia i ka wai a he 0.01% wale nō ka lawe ʻana i ka wai ma hope o 14 mau hola i ka wai. ʻO ke kaumaha molekala mai kahi o 80000 a 150000, me ka formability maikaʻi. Eia nō naʻe, ma muli o ke kiʻekiʻe o ka shrinkage rate, ʻoi aku ka maikaʻi o nā huahana pā mua i ka indentation, a maikaʻi ke kala ʻili o nā huahana, e maʻalahi ke kala.

2. Nā waiwai mīkini

Spunbond pp nonwoven lole he kiʻekiʻe ka maʻemaʻe, hana maʻamau, a no laila loaʻa nā waiwai mechanical maikaʻi loa. ʻOi aku kona ikaika, paʻakikī, a me ka elasticity ma mua o ka PE kiʻekiʻe. ʻO ka hiʻohiʻona koʻikoʻi ke kūpaʻa ikaika i ka luhi ʻana, me ka coefficient friction maloʻo e like me ka nylon, akā ʻaʻole maikaʻi e like me ka nylon ma lalo o ka lubrication aila.

3. Hana wela

ʻO ka lole spunbond pp nonwoven he pale wela maikaʻi, me kahi helu heheʻe o 164-170 ℃. Hiki ke hoʻomaʻemaʻe ʻia ka huahana a sterilized i nā mahana ma luna o 100 ℃. Ma lalo o ka ikaika o waho, ʻaʻole ia e deform a hiki i 150 ℃. ʻO ka mahana embrittlement ʻo -35 ℃, a hiki i ka embrittlement ma lalo o -35 ℃, me ka haʻahaʻa haʻahaʻa o ka wela ma mua o PE.

4. Hana uila

Spunbond pp nonwoven lole loaʻa kiʻekiʻe-frequency insulation hana. Ma muli o kona ʻaneʻane ʻaʻohe hoʻoheheʻe wai, ʻaʻole i hoʻopilikia ʻia kāna hana insulation e ka haʻahaʻa, a he kiʻekiʻe ka dielectric coefficient. Me ka piʻi ʻana o ka mahana, hiki ke hoʻohana ʻia e hana i nā huahana insulation uila wela. He kiʻekiʻe loa ka puʻupuʻu haʻihaʻi, kūpono ia no nā mea uila, a me nā mea ʻē aʻe. ʻO ke kūpaʻa uila maikaʻi a me ke kūpaʻa arc, akā kiʻekiʻe ka uila static a me ka maʻalahi o ka ʻelemakule ke pili me ke keleawe.

5. Ke kū'ē i ka wā

ʻO Spunbond pp ka lole ʻaʻole i ulana ʻia he maʻalahi loa i nā kukuna ultraviolet. ʻO ka hoʻohui ʻana i ka zinc oxide thiopropionate lauric acid ester a me ke kalapona ʻeleʻele e like me ka waiū keʻokeʻo hoʻopihapiha hiki ke hoʻomaikaʻi i kona kūʻokoʻa.
