Ma ke ʻano he kumu o nā ion calcium
ʻO ka hoʻohui ʻana i ka calcium chloride i ka wai ʻauʻau hiki ke hoʻolilo i ka wai wai i mea pale pH a hoʻonui i ka paʻakikī o ka wai loko, hiki ke hōʻemi i ka ʻino ʻana o ka pā pōhaku.Wahi a Le Chatelier a me ka hopena isoionic, ʻo ka hoʻonui ʻana i ka neʻe ʻana o nā ion calcium i loko o ka wai loko e hoʻolohi i ka hoʻoheheʻe ʻana o nā pūhui calcium e pono ai no nā hale paʻa.
ʻO ka hoʻohui ʻana i ka calcium chloride i ka wai o nā aquarium moana e hoʻonui i ka nui o ka calcium bioavailable i loko o ka wai, a hoʻohana nā mollusks a me nā holoholona coeltestinal i hānai ʻia i loko o nā aquarium e hana i nā pūpū calcium carbonate.ʻOiai hiki i ka calcium hydroxide a i ʻole ka calcium reactor ke hoʻokō i ke kumu like, ʻo ka hoʻohui ʻana i ka calcium chloride ke ala wikiwiki loa a loaʻa ka hopena liʻiliʻi i ka pH o ka wai.
Calcium chloride no nā hoʻohana ʻē aʻe
ʻO ke ʻano hoʻoheheʻe a me ka exothermic o ka calcium chloride e hoʻohana ʻia i loko o nā kini hoʻomehana ponoʻī a me nā pā hoʻomehana.
Hiki i ka calcium chloride ke kōkua i ka wikiwiki o ka hoʻonohonoho mua ʻana i loko o ke kaʻa, akā hiki i nā ion chloride ke hoʻopōʻino i nā kaola kila, no laila ʻaʻole hiki ke hoʻohana ʻia ka calcium chloride i loko o ke koʻa i hoʻoikaika ʻia.Hiki i ka calcium chloride anhydrous ke hāʻawi i kahi ʻano o ka makū i ka ʻuala ma muli o kāna mau waiwai hygroscopic.
I ka ʻoihana ʻaila, hoʻohana ʻia ka calcium chloride e hoʻonui i ka nui o ka brine paʻa ʻole, a hiki ke hoʻohui ʻia i ka pae wai o nā wai hoʻoheheʻe emulsified e kāohi i ka hoʻonui ʻana o ka pālolo.Hoʻohana ʻia ia e like me ka flux e hoʻohaʻahaʻa i ka helu heheʻe i ka hana o ka hana ʻana i ka metala sodium ma o ka hoʻoheheʻe electrolytic o ka sodium chloride e ke kaʻina Davy.Ke hana ʻia nā seramika, hoʻohana ʻia ka calcium chloride e like me kekahi o nā mea waiwai, e hiki ai ke hoʻokuʻu ʻia nā ʻāpana pālolo i loko o ka hopena, i maʻalahi ka hoʻohana ʻana i nā ʻāpana pālolo i ka wā grouting.
ʻO ka calcium chloride kekahi mea hoʻohui i loko o nā plastics a me nā mea hoʻopau ahi, ma ke ʻano he kānana kōkua i ka mālama ʻana i ka wai ʻino, ma ke ʻano he mea hoʻohui i loko o nā kapuahi puhi e hoʻomalu ai i ka hoʻohui a me ka hoʻopili ʻana o nā mea maka e pale aku ai i ka hoʻoponopono ʻana o ka uku, a ma ke ʻano he diluent i nā mea palupalu lole. .
