ʻulaʻula silica gel
ʻO kēia huahana he ʻāpana spherical a i ʻole ʻano ʻano like ʻole. ʻIke ʻia ka ʻulaʻula poni a i ʻole ʻalani ʻulaʻula me ka wai. ʻO kāna hana nui ʻo ka silicon dioxide a me ka hoʻololi ʻana o ke kala me ka haʻahaʻa like ʻole. Ma waho aʻe o ka hana e like me ka uliulisilica gel, ʻaʻohe cobalt chloride a ʻaʻohe mea ʻawaʻawa, ʻaʻohe pōʻino.

Alumino silica gel–AN
ʻO ke ʻano o ka aluminisilica gelhe melemele māmā a keʻokeʻo paha me ka ʻano molekiko kemika mSiO2 • nAl2O3.xH2O. Nā waiwai kemika paʻa. ʻAʻole hoʻopau ʻia, ʻaʻole hiki ke hoʻoheheʻe ʻia ke kumu ikaika a me ka waika hydrofluoric. Ke hoʻohālikelike ʻia me ka silica gel porous maikaʻi, ua like ka mana adsorption o ka haʻahaʻa haʻahaʻa (e like me RH = 10%, RH = 20%), akā ʻo ka mana adsorption o ka haʻahaʻa kiʻekiʻe (e like me RH = 80%, RH = 90%). ʻO 6-10% kiʻekiʻe ma mua o ka silica gel porous maikaʻi, a ʻo ke kūpaʻa wela (350 ℃) he 150 ℃ kiʻekiʻe ma mua o ka silica gel porous maikaʻi.

Alumino silica gel –AW
ʻO kēia huahana ke ʻano o ka alumino pale wai maikaʻisilica gel. Hoʻohana maʻamau ia e like me ka papa pale o ka gel silica porous maikaʻi a me ka gel silica alumini porous maikaʻi. Hiki ke hoʻohana wale ʻia i ka hihia o ka wai manuahi (wai wai). Inā loaʻa ka wai wai i ka ʻōnaehana hana, hiki ke loaʻa kahi hau haʻahaʻa me kēia huahana.

ʻeke liʻiliʻi desiccant
ʻO ka silica gel desiccant kahi ʻano mea ʻala ʻole, ʻono ʻole, ʻaʻohe mea ʻawaʻawa, kiʻekiʻe ka hana absorption material me ka ikaika adsorption capacity. pharmaceuticals.Silica gel descicant whisks away i ka makū e hana i ka aprotercyive environment of dryair no ka mālama pono. Hele mai kēia mau ʻeke silica gel i ka nui o ka nui mai 1g a i 1000g - no laila e hāʻawi iā ʻoe i ka hana maikaʻi loa.

Keokeo Silika Gel
ʻO ka silica gel desiccant kahi mea adsorption ikaika loa, ka mea maʻamau i hoʻomākaukau ʻia e ka hoʻopili ʻana i ka sodium silicate me ka sulfuric acid, ka ʻelemakule, ka waiʻawaʻawa a me ke ʻano o nā kaʻina hana ma hope o ka mālama ʻana. ʻO ka silica gel kahi mea amorphous, a ʻo kāna ʻano kemika he mSiO2. nH2O. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe, ʻaʻohe mea ʻawaʻawa a ʻono ʻole, me nā waiwai kemika paʻa, ʻaʻole e hoʻopili me kekahi mea koe wale nō ke kumu ikaika a me ka waika hydrofluoric. ʻO ka hoʻohui kemika a me ke ʻano kino o ka silica gel e hoʻoholo ai he mau hiʻohiʻona i paʻakikī ke hoʻololi i nā mea like ʻē aʻe. Loaʻa i ka silica gel desiccant ka hana adsorption kiʻekiʻe, ke kūpaʻa wela maikaʻi, nā waiwai paʻa paʻa, ka ikaika mechanical kiʻekiʻe, etc.

ʻAlu Silika Gel
Loaʻa i ka huahana ka hopena adsorption a me ka moisture-proof o ka silica gel pored maikaʻi, i ʻike ʻia i loko o ke kaʻina o ka hoʻoheheʻe ʻana i ka wai, hiki iā ia ke hoʻololi i ka poni me ka hoʻonui ʻana o ka hoʻoheheʻe ʻana o ka wai, a ma hope e huli ʻulaʻula. ʻAʻole hiki iā ia ke hōʻike wale i ka haʻahaʻa o ke kaiapuni, akā hōʻike ʻike ʻia inā pono e hoʻololi ʻia me kahi desiccant hou. Hiki ke hoʻohana wale ʻia ma ke ʻano he desiccant, a i ʻole hiki ke hoʻohana pū me ka silica gel fine-pored.
Hoʻokaʻawale: ʻo ka hōʻailona polū polū, hoʻololi ʻia ke kala polū i ʻelua mau ʻano: spherical particles a block particles.

Alani Silika Gel
Hoʻokumu ʻia ka noiʻi ʻana a me ka hoʻomohala ʻana o kēia huahana ma luna o ka gel silica hoʻololi kala ʻulaʻula, ʻo ia ka silica gel hoʻololi kala ʻalani i loaʻa ma ka hoʻokomo ʻana i ka gel silica pored maikaʻi me ka hui paʻakai inorganic. haumia kaiapuni. Ua lilo ka huahana i hanauna hou o nā huahana pili kaiapuni me kona kūlana ʻenehana kumu a me ka hana adsorption maikaʻi.
Hoʻohana nui ʻia kēia huahana no ka desiccant a e hōʻike ana i ke kiʻekiʻe o ka saturation o ka desiccant a me ka haʻahaʻa o ka hoʻopaʻa ʻana i hoʻopaʻa ʻia, nā mea hana pololei a me nā mika, a me ka moisture-hōʻoia o ka pahu ākea a me nā mea kani.
Ma waho aʻe o nā waiwai o ke kāpili polū, loaʻa nō hoʻi ka maikaʻi o ke kolu ʻalani ʻaʻohe cobalt chloride, non-toxic a me ka pōʻino. Hoʻohana pū ʻia, hoʻohana ʻia ia e hōʻike i ke kiʻekiʻe o ka absorption moisture o ka desiccant, i mea e hoʻoholo ai i ka haʻahaʻa pili o ke kaiapuni. Hoʻohana nui ʻia i nā mea hana pololei, lāʻau lapaʻau, petrochemical, meaʻai, lole, ʻili, nā mea hana hale a me nā kinoea ʻoihana ʻē aʻe.
