Ma The Field Of Organic Silicon, hiki ke hoʻokaʻawale ʻia nā mea hoʻoheheʻe kino kino i lalo i nā mea paʻa a me ka wai, a ua hoʻohana nui ʻia nā mea ʻelua i kēia manawa i nā ʻoihana nui, e like me ka potting glass glue, ka wai silicone organik, a me ka hoʻopaʻa ʻana i nā huahana silicon Rubber, uila. sealing accessories, etc. He nui nā mea like ma waena o kā lākou kahua noi a me nā waiwai waiwai, a ʻokoʻa kā lākou hana hana.Ma ke kahua o nā huahana, ʻo kā lākou mau kuleana a me nā hana he mea like.He aha nā ʻokoʻa ma waena o nā mea a me nā huahana?

ʻO ka ʻokoʻa nui ma waena o ka gel silica wai a me ka gel silica paʻa: ʻo kekahi wai a paʻa kekahi;akā ma hope o ka hana ʻana i ka huahana i hoʻopau ʻia, ʻaʻole maʻalahi nā mea ʻelua e ʻike.ʻO ka wai silica gel ka wai a loaʻa ka wai.Paʻa ka silica gel paʻa a ʻaʻohe wai.

Nā kahua hoʻohana like ʻole:
(1) Hoʻohana maʻamau ka silicone wai i nā huahana pēpē, nā huahana kīhini silicone a me nā huahana olakino, hiki ke hoʻopili pololei i ka meaʻai a me ke kino kanaka;

(2) Hoʻohana pinepine ʻia ka silica gel paʻa no nā mea e pono ai i kēlā me kēia lā, nā ʻāpana ʻenehana a me nā ʻāpana kaʻa;

(3) Ka palekana o ka wai silica gel a me ka silica gel paʻa: ʻO ka wai silica gel kahi meaʻai-palekana kiʻekiʻe.ʻAʻohe mea kōkua e like me ka vulcanizing agent i hoʻohui ʻia i ka wā o ke kaʻina hana.Hoʻokumuʻia ka mea hoʻopaʻa ma ka hoʻopaʻaʻana.

He mea translucent ka silica gel paʻa.Pono ka Vulcanization e hoʻolōʻihi i ka manawa hoʻōla.

Molina:

Liquid Silicone (LSR): ʻO ka inoa piha ʻo ia ka hoʻoheheʻe ʻana i ka wai silicone rubber, a ʻo ka mea hana vulcanization he mīkini hoʻoheheʻe injection.He mea maʻalahi loa ke kaʻina hana mīkini hoʻoheheʻe ʻia, kiʻekiʻe ka pololei o ka huahana, a kiʻekiʻe ka hopena (ua hui ʻia ke kāʻei A / B no kekahi mau kekona i kahi mahana).Hoʻohui ʻia nā mea a hoʻohui ʻia me ke kala kala a me ka catalyst e hoʻokomo i loko o ka lua mold me ka ʻole o ka hana lima.Loaʻa ka maikaʻi o ka huahana ʻO ka huahana he wai maikaʻi, hoʻolōʻihi ikaika a me ke kūpaʻa, a ua hui pū ʻia ka mold i hoʻoheheʻe ʻia, no laila, loaʻa i ka huahana kahi awa i hoʻopaʻa ʻia a ʻaʻohe laina hoʻokaʻawale.

Silicone Solid: He paʻa ka mea maka no ka hoʻoheheʻe ʻana i ka gel silica paʻa.Ma hope o ka hui ʻia ʻana o ka mea hoʻohua silicone rubber e kahi hui, pono ia e hoʻohui i ke kala kala a me ka catalyst, a laila ʻokiʻoki i kahi nui kūpono a hoʻokomo lima ʻia i loko o ka lua mold e hana a hoʻōla.Pono ke kaʻina hana maʻalahi e lawe i ka mold a hoʻokuʻu i ka mea.Ma muli o ka paʻa o ka mea, ʻoi aku ka haʻahaʻa o ka wai a me ke kūpaʻa ma mua o ka wai.ʻAʻohe puka i hoʻopaʻa ʻia i ka huahana, a ʻo ka huahana i hoʻopau ʻia e loaʻa nā laina hoʻokaʻawale luna a me lalo.

He aha ka ʻokoʻa ma waena o Liquid Silicone a me Solid Silicone Materials?
Hana ʻia ka silica gel paʻa me ke aniani wai (sodium silicate) ma ke ʻano he mea maka, hydrolyzed i loko o kahi mea ʻakika e hana ai i gel, a laila hana ʻia i silica gel ma o ka wā ʻelemakule, holoi, hoʻomaloʻo, etc. paʻa translucent a keʻokeʻo paha.Loaʻa nā huahana ma ka mākeke irregular granular, spherical, a me microspherical silica gels, ka mea maʻamau i hoʻohana ʻia e like me nā catalysts no ka vulcanization i nā hana moe fluidized.

ʻelua.Ke hoʻohana ʻia ma ke ʻano he mea lawe catalyst, hoʻokomo pinepine ʻia ka silica gel i loko o kahi hopena i loaʻa nā mea hana catalytically, i komo ai ka hopena i loko o nā pores o ka silica gel, a ua māhele ʻia nā mea hana ma ka ʻili o ka silica.ʻO ka hoʻomaloʻo ma o ka hoʻomaloʻo ʻana, ka hoʻoulu ʻana, a me nā mea ʻē aʻe. He mana koʻikoʻi ke ʻano o ka pore o ka silica gel i nā waiwai o ka catalyst i kākoʻo ʻia i hoʻomākaukau ʻia, e like me ka nui o ka pore a me ka puʻupuʻu nui o ka silica gel.ʻO ka mea maʻamau, ua kapa ʻia ka silica gel me ke anawaena pore awelika ma lalo o 15 a 20;a me ka awelika pore anawaena o ka oi ma mua o 40 a 50 angstroms ua kapaia coarse pore silica gel.

Hoʻolauna kaʻina hana silicone wai

Hoʻohana ʻia ka gel silica wai i ka ʻoihana e hoʻoheheʻe i ka wai sodium i loko o ka silica sol ma o ka hoʻololi ion.He wai keʻokeʻo keʻokeʻo translucent me ke kūpaʻa kiʻekiʻe.Lilo ka silica gel paʻa i paʻa porous ma hope o ka maloʻo ʻana.No ka laʻana, i ka hoʻomākaukau ʻana o (phosphorus-molybdenum-niobium-oxygen)/silica catalyst no ka hoʻomākaukau ʻana i ka acrylonitrile e ka oxidative oxidation o propylene, ua hui pū ʻia kahi hopena i loaʻa nā mea ikaika me ka silica sol, a ua hoʻomākaukau ʻia nā microspheres e ka spraying catalyst.
