Kiʻekiʻe kiʻekiʻe kiʻekiʻe-papaʻai calcium hydroxide
Edible calcium hydroxide (kahi calcium ≥ 97%), i ʻike ʻia hoʻi he lime hydrated, lime hydrated.ʻAno: ʻO ka pauka keʻokeʻo, me ka ʻono alkali, me ka ʻono ʻawaʻawa, ka mānoanoa pili 3.078;Hiki iā ia ke komo i ka CO₂ mai ka lewa a hoʻololi iā ia i calcium carbonate.E wela a ma luna o 100 ℃ e nalowale ka wai a hana i kahi kiʻi carbonate.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, ikaika alkaline, pH 12.4.Hiki ke hoʻoheheʻe ʻia i loko o nā hāʻina saturated o ka glycerol, hydrochloric acid, nitric acid, a me ka sucrose, insoluble in ethanol.
Ma ke ʻano he pale, neutralizer, a me ka mea hoʻoikaika paʻa, hiki ke hoʻohana ʻia ka calcium hydroxide meaʻai i ka lāʻau lapaʻau, ka synthesis o nā mea hoʻohui meaʻai, ka synthesis o nā biomaterials high-tech HA, ka synthesis o VC phosphate esters e like me nā mea hoʻohui hānai, a me ka synthesis o calcium naphthenate, calcium lactate, calcium citrate, mea hoʻohui i loko o ka ʻoihana kōpaʻa, mālama wai, a me nā kemika kūlohelohe kiʻekiʻe ma muli o kāna kuleana i ka hoʻoponopono pH a me ka coagulation.Hāʻawi i ke kōkua kūpono i ka hoʻomākaukau ʻana i nā mea hoʻoponopono acidity a me nā kumu calcium e like me nā huahana semi-finished edible, nā huahana konjac, nā huahana inu, nā enemas lāʻau lapaʻau, etc.
Packaging, mālama a me ka lawe ʻana
Hoʻopili ʻia i loko o nā ʻeke i ulana ʻia me nā ʻeke kiʻiʻoniʻoni polyethylene, me ke kaumaha ʻupena he 25kg no kēlā me kēia ʻeke.Pono e mālama ʻia i loko o kahi hale kūʻai maloʻo.E pale pono i ka wai.Hōʻalo i ka mālama ʻana a me ka lawe ʻana me nā waikawa.I ka wā o ka lawe ʻana, pono e pale i ka ua.Ke hiki mai ke ahi, hiki ke hoʻohana ʻia ka wai, ke one, a i ʻole ka mea kinai ahi mau e kinai ai.
1. Pehea ʻoe e hoʻokaʻawale ai i ka calcium hydroxide mai ka calcium oxide?He aha ke ʻano o ka hoʻokaʻawale ʻana iā lākou?Ma hea e hoʻokaʻawale ai?
E pili ana i kēlā mau nīnau, ʻo mākou nā mea hana Calcium hydroxide, e hāʻawi iā ʻoe i ʻehā mau ala maikaʻi e like me kēia,
1. E hookomo i ka pauda iloko o ka paipu hoao, e hookomo i ka pauda kalapona nui loa, e hookui i ka waha omole me ka puka pahu hookahi me ka paipu, a e kau i ka omole kuni waiona ma ka waha o ka ohe.
2. E wela i ka wela wela me ka hoʻohana ʻana i ka mea puhi waiʻona
3. Ma hope o ka pane kūpono, ho'ōki i ka wela.
4. E hooluolu i ka paipu hoao a hiki i ka wela o ka lumi, e ninini i ke koena paa, a e hoomaopopo i ke kala o ka huahana.
No ka mea, ʻo CaO+3C=(wela kiʻekiʻe) CaC2+CO ↑, Ca (OH) 2 ʻaʻole pane me C. ʻO ke kalapona he paʻa ʻeleʻele, ʻo ka calcium carbide he hina hina, ʻeleʻele melemele a ʻeleʻele paha, a ʻo ka calcium hydroxide he keʻokeʻo. paʻa.]Inā ʻeleʻele a keʻokeʻo ka waihoʻoluʻu huahana, ʻo Calcium hydroxide wale nō ka mea i hōʻike ʻia.
Inā ʻeleʻele a hina ka waihoʻoluʻu huahana, ʻeleʻele melemele a ʻeleʻele paha, hōʻike ia he Calcium oxide wale nō.
Ka hopena: ʻO nā ʻano hana ʻehā ma luna nei e hoʻokaʻawale i ka Calcium oxide mai ka Calcium hydroxide.He mea maʻalahi ke ala.Hana nā kānaka ʻoihana i nā mea ʻoihana.Inā makemake ʻoe e ʻike hou aku, e ʻoluʻolu e hoʻolohe i kā mākou mea hana Calcium hydroxide.
2. Pehea e hoʻololi ai ka calcium hydroxide i Calcium oxide?He aha ke ʻano o ka Calcium hydroxide e lilo i Calcium oxide?
He mea maʻalahi loa ia no ka hoʻololi ʻana i ka calcium hydroxide i Calcium oxide, ʻo ia ke ʻano kemika maʻamau.ʻO mākou nā mea hana calcium hydroxide e haʻi iā ʻoe e pili ana i kēia.
Pono e hana ka calcium hydroxide me carbon dioxide e hana i ka calcium carbonate, hiki ke hoʻomehana ʻia i ka wela kiʻekiʻe e hana i ka calcium oxide.
1. Hoʻopili ka calcium hydroxide me carbon dioxide e hana i ka ua a me ka wai.
2. Hiki ke hana ʻia ka calcium oxide a me ka carbon dioxide ma ka hoʻomehana ʻana i ka ua calcium carbonate i ka wela kiʻekiʻe (hoʻomehana i 900 ℃ ma 101.325 kPa).
ʻO nā mea hoʻohana a me nā waiwai o Calcium oxide:
1. Hiki ke hoʻohanaʻia e like me ka mea hoʻopihapiha, no ka laʻana: ma keʻano he mea hoʻopihapiha no nā epoxy adhesives;
2. Hoʻohana ʻia ma ke ʻano he analytical reagent, carbon dioxide absorber no ka nānā ʻana i ke kinoea, spectroscopic analysis reagent, high-purity reagent no nā kaʻina epitaxial a me ka diffusion i ka hana semiconductor, ka hoʻomaloʻo ʻana i ka amonia hale hana, a me ka waiʻona dehydration.
3. Hiki ke hoʻohana ʻia e like me ka mea maka no ka hana ʻana i ka calcium carbide, soda lehu, bleaching pauka, a me nā mea ʻē aʻe, a me ka hana ʻili, hoʻomaʻemaʻe wai hoʻomaʻemaʻe, Calcium hydroxide a me nā pūhui calcium like ʻole;
4. Hiki ke hoʻohana 'ia ma ke 'ano he mea hale, ka mea hao hao, ka mea ho'okele sima, a me ka flux no ka pauka fluorescent;
5. Hoʻohana ʻia e like me ka mea kanu aila decolorizer, lawe lāʻau lapaʻau, mea hoʻomaʻemaʻe lepo, a me nā mea kanu calcium;
6. Hiki ke hoʻohana ʻia e like me nā mea refractory a me nā desiccants;
7. Hiki ke hoʻohana 'ia no ka hoʻomākaukau 'ana i ka mīkini mahiʻai No.1 a me No.2 adhesives a me ka wai epoxy adhesives, a no hoi me he reactant no prereaction me 2402 resin;
8. Hoʻohana ʻia no ka hoʻomaʻamaʻa ʻana i ka wai ʻawaʻawa a me ka hoʻomaʻamaʻa ʻana i ka lepo;
9. Hiki ke hoʻohana ʻia e like me kahi mea pale no ka pani ʻana o ka paila, me ka hoʻohana ʻana i ka hiki ke hoʻoheheʻe ʻia o ka lime e mālama i ka ʻili metala o ka ʻōnaehana mahu wai paila a maloʻo a pale i ka corrosion.He kūpono ia no ka pale pani lōʻihi o ka haʻahaʻa haʻahaʻa, ke kaomi waena, a me nā pahu pahu pahu liʻiliʻi;
10. ʻO ka calcium oxide kahi mea hoʻoheheʻe kumu, ʻo ia ka mea maʻalahi i ka haʻahaʻa.He maʻalahi ke komo i ka carbon dioxide a me ka wai mai ka lewa.Hiki iā ia ke hana me ka wai e hoʻomākaukau ai i ka Calcium hydroxide, nona ka hopena hui.
