He aha ka ʻokoʻa ma waena o ka desiccant i loko o ka ʻeke meaʻai?

He mea maʻamau ka Desiccant i ke ola o kēlā me kēia lā.ʻO ka maʻamau, hiki iā ʻoe ke kūʻai i nā ʻeke meaʻai nut, he desiccant.ʻO ke kumu o ka desiccant e hoʻemi i ka haʻahaʻa o ka huahana a pale i ka huahana mai ka hoʻopōʻino ʻia e ka makū, no laila e pili ana i ka maikaʻi o ka huahana.ʻono.ʻOiai ke kuleana o ka desiccant e hoʻomoʻi i ka haʻahaʻa o ka ea i loko o ka huahana, ʻokoʻa ke kumu o ka hoʻohana a me nā mea.Aia ʻelua ʻano e like me ke kemika a me ka physics:
Mea hoʻomaloʻo kemika:
Mea hoʻoheheʻe calcium chloride
Hana ʻia ka calcium chloride me ka calcium carbonate kiʻekiʻe a me ka waikawa hydrochloric e like me nā mea maka.Ua hoʻomaʻemaʻe ʻia e ka hoʻohālikelike ʻana, kānana, evaporation, ʻike a me ka maloʻo.Hoʻohana pinepine ʻia e like me ka calcium fortifier, chelating agent, curing agent a desiccant i ka ʻoihana meaʻai.Eia kekahi, hoʻohana ʻia ia ma ke ʻano he desiccant no nā kinoea.Hiki ke hoʻohana ʻia e hoʻomaloʻo i nā kinoea kūʻokoʻa, alkaline a i ʻole acid a hoʻohana ʻia ma ke ʻano he dehydrating agent no ka hana ʻana i nā ethers, alcohols, propylene resins, etc. i ka wai a me ke kala ole.

2. Mea hoʻoheheʻe kiʻekiʻe
ʻO kāna mea nui ʻo ka calcium oxide, ka mea e hoʻokō ai i ka hoʻoheheʻe ʻana i ka wai e ka hopena kemika, hiki ke hoʻomaloʻo i ke kinoea kūʻokoʻa a i ʻole ka alkaline, a hiki ʻole ke hoʻololi.ʻO ka mea maʻamau ka hoʻohana ʻana i ia mau desiccants i "nā keke hau".Eia kekahi, hoʻohana pinepine ʻia i nā mea uila, ka ʻili, nā lole, nā kāmaʻa, ke kī, a me nā mea ʻē aʻe, akā no ka mea he alkali ikaika ka quicklime, he mea ʻino loa ia, a i ka wā e ʻeha ai nā maka o nā ʻelemakule a me nā keiki, ke hele mālie nei Ua hoʻopau ʻia.
Desiccant kino:
Silica gel desiccant
ʻO ka mea nui he silica, i hoʻopili ʻia a i hoʻopaʻa ʻia e nā mineral maoli.Ma ke ʻano he desiccant, ʻo kona ʻano microporous kahi pilina maikaʻi no nā mole wai.ʻO ke kaiapuni hoʻoheheʻe wai kūpono loa no ka silica gel ʻo ka lumi wela (20 ~ 32 ° C) a me ka haʻahaʻa kiʻekiʻe (60 ~ 90%), hiki ke hoʻemi i ka haʻahaʻa pili o ke kaiapuni ma kahi o 40%.Loaʻa i ka silica gel desiccant nā hiʻohiʻona o ke kala ʻole, ʻaʻala ʻole a ʻaʻohe mea ʻawaʻawa, kūpaʻa i nā waiwai kemika a ʻoi aku ka maikaʻi o ka hana ʻana i ka wai.Hoʻohana nui ʻia i nā mea kani, nā mea kani, ka ʻili, nā ukana, nā meaʻai, nā textiles, nā mea hana a pēlā aku.ʻO kāna kuleana ʻo ka mālama ʻana i ka haʻahaʻa pili o ke kaiapuni i ka wā o ka mālama ʻana a me ka lawe ʻana i mea e pale ai i ka makū, ka lepo a me ka ʻōpala.He mea pono e hoʻomaopopo ʻo ia wale nō ka desiccant i ʻae ʻia ma ka EU.
3. Palolo (montmorillonite) desiccant
ʻO ke ʻano hiʻohiʻona e like me ka pōpō hina, kūpono loa no ka hoʻomaʻamaʻa ʻana i ka makū ma ke kaiapuni ma lalo o 50 °C.Inā ʻoi aku ka kiʻekiʻe o ka mahana ma mua o 50 ° C, ʻoi aku ka nui o ka "hoʻokuʻu wai" o ka pālolo ma mua o ke kiʻekiʻe o ka "wai absorption".Akā ʻo ka maikaʻi o ka pālolo ʻo ia ka maʻalahi.Hoʻohana nui ʻia ka desiccant i ka mālama olakino olakino, ka meaʻai meaʻai, nā mea optical, nā huahana uila, nā huahana koa a me nā huahana kīwila.Ma muli o ka hoʻohana ʻana i ka bentonite maʻemaʻe kūlohelohe, loaʻa iā ia nā ʻano o ka adsorption ikaika, adsorption wikiwiki, kala ʻole, non-toxic, ʻaʻohe haumia kaiapuni a ʻaʻohe hoʻopili pili.He pili kaiapuni, kala ʻole a ʻaʻohe mea ʻawaʻawa, ʻaʻohe mea pōʻino i ke kino kanaka, a he hana adsorption maikaʻi.Ka hana adsorption, static dehumidification a me ka wehe ʻana i ka ʻala.
