Ka Moolelo o ka Hooulu ana i ka Aila Silicone Textile

Hoʻokumu ʻia ka mea hoʻomaʻemaʻe silicone organik i ka makahiki 1950.A ua hele kona hoʻomohala ʻana ma nā pae ʻehā.

1. ʻO ka hanauna mua o ka silicone softener

I ka makahiki 1940, hoʻomaka ka poʻe e hoʻohana i ka dimethyldichlorosilance e hoʻomoelole lolea loaʻa i kekahi ʻano hopena wai.I ka makahiki 1945, ua hoʻoluhi ʻo Elliott o ʻAmelika Hui Pū ʻIa Nui (GE) i nā fibers i loko o kahi solution wai alkaline me ka sodium methyl silanol.Ma hope o ka hoʻomehana ʻana, loaʻa ka hopena wai maikaʻi o ka fiber.

I nā makahiki 50 mua, ua ʻike ʻo American Dow Corning Company i nā lole i mālama ʻia e ka polysiloxane me Si-H he hopena wai maikaʻi a me ka nui o ka ea.Akā ʻilihune ka manaʻo o ka lima a he paʻakikī hoʻi ke kiʻi silicone, palupalu a maʻalahi hoʻi e hāʻule.A laila ua hoʻohana pū ʻia me ka polydimethylsiloxane (PDMS).ʻAʻole i loaʻa wale ka hopena wai maikaʻi akā ʻo ka manaʻo lima palupalu.Ma hope o kēlā, ʻoiai ua ulu wikiwiki nā huahana silicone ma ka honua holoʻokoʻa a uhi ʻia i nā ʻano like ʻole, no ka mea, ua pili lākou i nā hui mechanical o dimethyl.ʻaila silicone, i hui pū ʻia me nā huahana aila silicone.ʻO lākou ka hanauna mua o ka mea hoʻomaʻemaʻe silicone textile.

ʻO ka hanauna mua o nā mea hoʻomaʻemaʻe silicone i hoʻopili pololei ʻia i ka ʻaila silicone e ka mechanical emulsification.Akā no ka mea ʻaʻohe hui ikaika o ka ʻaila silicone ponoʻī, ʻaʻole hiki ke hoʻopaʻa maikaʻi i ka lole a ʻaʻole hiki ke holoi ʻia.No laila ʻaʻole ia e loaʻa ka hopena maikaʻi loa ke hoʻohana wale ʻia.

2. ʻO ka lua o ka hanauna o ka silicone softener

I mea e lanakila ai i nā hemahema o ka hanauna mua o ka mea hoʻomaʻamaʻa silicone, ua loaʻa i nā mea noiʻi ka lua o ka hanauna o ka silicone emulsion me nā pāpale hydroxyl.ʻO ka mea palupalu ka nui o ka hydroxyl silicone oil emulsion a me ka hydrogen silicone oil emulsion, hiki ke hana i kahi hoʻonohonoho crosslinking network ma ka ʻili lole i mua o ka catalyst metala, hāʻawi i nā lole i ka palupalu nui, ka holoi a me ka paʻa.

Akā, no ka mea he hana hoʻokahi a maʻalahi i ka demulsified a lana ka aila, ua hoʻololi ʻia e ke kolu o ka hanauna o ka silicone softener ma mua o ka hoʻohana nui ʻia.

3. ʻO ke kolu o ka hanauna o ka silicone softener

ʻO ke kolu o ka hanauna omea hoʻomaʻemaʻe siliconeua hoʻomohala i ka wikiwiki loa i ʻike ʻia i nā makahiki i hala iho nei.Hoʻokomo ia i nā ʻāpana ʻē aʻe a i ʻole nā ​​hui ikaika i loko o nā kaulahao nui a ʻaoʻao paha o polysiloxane, e like me ka polyether group, epoxy group, alcohol hydroxyl group, amino group, carboxyl group, ester group, sulfhydryl group, etc. nā ʻano lole a pau.Ke hilinaʻi nei hoʻi i nā hui, hiki iā ia ke hāʻawi i nā lole i ke ʻano ʻokoʻa.

Akā ma ka maʻamau, ʻo ke kolu o ka hanauna o ka silicone softener e hui pū me ka polysiloxane monofunctional e hoʻokō i ka hopena mālama pono.He paʻakikī ke kāohi i ka helu hui ʻana, ka mea i hoʻoikaika nui i ka hana a me ka noi.

4. ʻO ka hā o ka hanauna silicone softener

Hoʻololi hou ʻia ka hā o ka ʻehā o ka hoʻomaʻamaʻa silicone i ke kolu o ka hanauna o ka silicone softener e like me ka hopena hoʻopau pono o ka lole.ʻO ia ka mea i hoʻokomo i nā pūʻulu ʻoi aku ka ikaika, hiki ke hoʻokō i nā koi hana a pau o ka lole me ka ʻole o ka hui ʻana.

ʻO nā lole i mālama ʻia e ka mea hoʻomaʻamaʻa silicone i hoʻololi ʻia me nā ʻano hui like ʻole i ʻoi aku ka maikaʻi o ka palupalu, ka holoi ʻana, ka elasticity a me ka hydrophilicity, a me nā mea ʻē aʻe. i kēia manawa.
