Calcium chlorideikemikari inoumbwa ne chloride uye calcium elements.Iyo kemikari formula ndeye CACL2, inovava zvishoma.Iyo yakajairika ion-mhando halide, ine zvichena, zvimedu zvakaoma kana zvidimbu patembiricha yepakamuri.Zvishandiso zvaro zvakajairika zvinosanganisira saline, migwagwa inonyungudika uye desiccants inoshandiswa mumidziyo yefiriji.
Calcium chloridekubva pakuonekwa inonyanya kukamurwa kuita mvura calcium chloride uye yakasimba calcium chloride.Liquid calcium chloride iine aqueous solution ye calcium chloride, general content ye calcium chloride i27~42%.Kana izvo zviri mu calcium chloride zvakanyanyisa, mhinduro yacho ichave yakanyanya viscous, tembiricha inodzikira mhinduro kusimba, pane chekufambisa, kuburitsa, kushandisa kuomerwa uye mamwe matambudziko.Solid calcium chloride inogona kukamurwa kuita flake, bhora, upfu uye zvimwe zvitatu, kuumbwa kwayo kunokamurwa kuita calcium chloride dihydrate kana anhydrous calcium chloride.Zviri mu calcium chloride mu calcium chloride dihydrate inowanzo 72 ~ 78%, uye zviri mu calcium chloride mu anhydrous calcium chloride zvinodarika 90% kana 94% (kunyanya spherical calcium).
Kazhinji, kugadzirwa kwe spherical calcium yakaoma, kugadzikana kwemaitiro hakuna kukwirira, maitiro ekushanda akasimba, kushandiswa kwesimba rekugadzira kwakakwira zvishoma, asi zvigadzirwa zvayo zvine zvakanakira kutaridzika kwakanaka, mvura yakanaka yeChemicalbook, kwete. guruva, pasina caking, hazvisi nyore kutora unyoro, saka mutengo wekutengesa we spherical calcium calcium chloride yakakwirira kudarika flake kana poda calcium chloride, inonyanya kushandiswa kudzimba desiccant, kunze Kwechando uye ice melting agent.Negiredhi, calcium chloride inogona kukamurwa kuita maindasitiri giredhi calcium chloride uye chikafu giredhi calcium chloride.Kuenzaniswa neindasitiri giredhi calcium chloride, chikafu giredhi calcium chloride ine zvakaomarara zvinodiwa pakudzora kugadzirwa uye kuchena kwechigadzirwa.Miyero yenyika yakawedzera zviratidzo zvakaita seruvara, heavy metal (lead, arsenic) uye fluorine zvirimo zvezvigadzirwa.Chikafu giredhi calcium chloride inogona kushandiswa se stabilizer, solidifying agent, thickening agent, nutritive fortifying agent, desiccant, etc., kushandiswa kwayo kunosanganisira zvigadzirwa zvebhinzi, mutete cream, zvinwiwa zvinotapira, muto unotapira, jamu, kusanganisa mvura uye kugadzira indasitiri yechikafu. rubatsiro.
Main applications:
Calcium chlorideinoumbwa neklorini uye calcium uye ine kemikari formula CaCl2.Iyo yakajairwa ionic halide, chena yakasimba pakamuri tembiricha uye isina kwayakarerekera mune aqueous mhinduro.Calcium chloride, mahydrates ayo uye zvigadziriso zvine zvakakosha mukugadzira chikafu, zvekuvaka, mushonga uye biology.
Kushandiswa kwemaindasitiri
1, inoshandiswa se-multi-purpose desiccant, yakadai senitrogen, oksijeni, hydrogen, hydrogen chloride, sulfur dioxide uye mamwe magasi ekuomesa.Inoshandiswa se dehydrating agent mukugadzira doro, esters, ethers uye acrylics.Calcium chloride aqueous solution ndiyo yakakosha firiji yemuchina wefiriji nekugadzira ice.Inogona kukurumidza kuomeswa kwekongiri uye kuwedzera kutonhora kwekudzivirira kwekuvaka dhaka.Iyo yakanaka yekuvaka antifreeze agent.Inoshandiswa sechiteshi antifogging agent uye muunganidzi weguruva wemugwagwa, jira rinodzoreredza moto.Inoshandiswa seanodzivirira mumiriri uye yekunatsa mumiriri wealuminium magnesium metallurgy.Iyo inonamira yekugadzira pigment yegungwa.Inoshandiswa kugadzira marara mapepa.Ndiyo yakasvibiswa yekugadzirwa kwekarusiyamu munyu.
2. Chelating agent;Curing agent;Calcium fortifier;Refrigerating refrigerant;Desiccant;Anticoagulant;Microbiotics;Pickling agent;Tissue kunatsiridza.
3, inoshandiswa se desiccant, guruva remumugwagwa rinounganidza, fogging agent, machira anodzoreredza moto, anochengetedza chikafu uye anoshandiswa mukugadzira calcium munyu.
4, inoshandiswa sekuwedzera mafuta ekuzora.
5, inoshandiswa seanalytical reagent.
6. Inonyanya kushandiswa pakurapa tetany, urticaria, exusive edema, intestinal uye ureter colic, magnesium poisoning uye zvichingodaro zvinokonzerwa nekuderera kweropa calcium.
7, inoshandiswa muindasitiri yezvekudya secalcium inosimbisa mumiriri, kurapa mumiriri, chelating agent uye desiccant.
8, inogona kuwedzera permeability yebacterial cell wall.
Kushandiswa kwezvokudya
1. Calcium chlorideinogona kuwedzerwa kune zvekudya se calcium enhancer, kana se coagulant ye tofu uye cheese.
2. Calcium chloride inogona kuwedzerwa kune doro uye zvinwiwa zvinotonhorera kugadzirisa PH uye kuoma kwezvinwiwa.
3. Inoshandiswa mumhizha yezvokudya se calcium fortifying agent, kuporesa mumiririri, chelating agent uye desiccant.

Kugadzirira nzira:
1.Calcium chloride dihydrate (dehydration method) nzira:
Iyo inodyika anhydrous calcium chloride chigadzirwa chakagadzirwa nekuomesa uye kupera mvura yecalcium chloride dihydrate pa200 ~ 300 ℃.
Iyo Chemical reaction equation ndeiyi inotevera:
Nekusarerekera calcium chloride mhinduro, pfapfaidzo yekuomesa shongwe inogona kushandiswa pa 300 ℃ inopisa gasi kuyerera kwekupfapfaidza kuomesa kupera mvura, kugadzirira anhydrous calcium chloride poda yakapera zvigadzirwa.
2.Spray kuomesa uye dewatering nzira:
Iyo yakacheneswa yakanatswa karusiyamu chloride mhinduro, iyo yakabvisa arsenic uye inorema simbi, inopfapfaidzwa kuita mhute pamusoro peiyo spraying shongwe kuburikidza nemuromo, uye countercurrent kusangana ne 300 ℃ inopisa gasi inoyerera kuti iome uye ipere mvura, uye ipapo poda anhydrous calcium chloride. inowanikwa kugadzira zvinodyiwa anhydrous calcium chloride zvigadzirwa.
3. Nzira yedoro raamai:
Mushonga wemvura unowanikwa nekuwedzera lime mukaka kudoro raamai mukuita soda ash neammonia alkali nzira, iyo inoumbwa nekubuda, kusungirira, kutonhora uye kusimba.
4. Musanganiswa decomposition nzira:
Inogadzirwa nekuita kwe calcium carbonate (limestone) ine hydrochloric acid.
Chemical reaction equation: CaCO3+2HCl=CaCl2+H2O+CO2↑.
Mushure mokunge matanho ari pamusoro apa apera, kupisa kunopisa kusvika ku260 degrees Celsius, evaporation uye kupera simba.
5.Kunatsa nzira:
Iyo ne-chigadzirwa mukugadzirwa kwe sodium hypochlorite inonatswa.
A by-chigadzirwa cheSolvay process yekugadzirira sodium carbonate.
Ca(OH)2 + 2NH4Cl → CaCl2 + 2NH3 + 2H2O
Operation precautions:
Kuvharwa kushanda kuti kuwedzere kufefetedza.Vashandi vanofanira kunge vakanyatsodzidziswa uye kunyatsotevedzera maitiro ekushanda.Zvinokurudzirwa kuti vashandisi vapfeke masiki ega-priming filter dust masks kudzivirira guruva.Pakubata, kurodha uye kuburitsa kunofanirwa kuitwa kudzivirira kukanganisa kurongedza uye midziyo.
Kuchengetedza:
Chengetedza muimba yekuchengetera inotonhorera, ine mhepo.Packing midziyo inofanira kuvharwa uye kuchengetedzwa kubva kunyorova.Chengetedza zvakasiyana kubva kune zvinonaka.
Chigadzirwa kurongedza: 25KG / BAG
