Calcium hydroxide: kaddarorin da aikace-aikace

Ca (OH) 2 shine calcium hydroxide (daga Latin Calcium hydroxide), wannan abu ne mai mahimmanci. Yana da yanayi dabi'a mai tushe. Yana da launi mai laushi mai launin launi ko launin lu'u-lu'u. Zai iya ɓarkewa a kan dumama, wanda ya haifar da sakin oxyci. Ba shi da kyau mai narkewa cikin ruwa. A wannan yanayin, bayani mai mahimmanci na allurar hydroxide shi ne, ta wurin abubuwan da ke cikin sinadarai, cibiyar tsakiya. A gaban karafa, zai iya saki hydrogen, wanda aka gane da shi azaman gas.

Calcium hydroxide lokacin da ake amfani da shi cikin bakin ko sakamakon sakamakon inhalation na aerosol za a iya ɗauka cikin kyallen takarda kuma tara a cikinsu. A dakin ɗakunan aji na al'ada na 20-22 digiri, wannan abu ba kusan an ɗauke shi ba, amma yayin da spraying da barbashi na iya zama haɗari ga lafiyar. Samun fata, a cikin fili na numfashi ko mucous membranes of eyes, calcium hydroxide yana da irritating, ko da sakamako mai ɓarna. Haduwa mai tsawo tare da fata zai iya haifar da dermatitis. Har ila yau, ƙwayar kwakwalwa zai iya rinjaye shi ta hanyar aiki na yau da kullum na ma'aunin man fetur hydroxide.

Wannan sunadarai fili ya da yawa maras muhimmanci sunayen, kamar slaked lemun tsami (shi ne ta shirya slaking alli oxide tare da bayyana ruwa) Lemun tsami ruwa (shi ne bayyananne ruwa-ruwa bayani). Sauran sunayen: auduga foda (alli hydroxide a matsayin bushe foda) da kuma lemun tsami madara (cikakken mai ruwa-ruwa mai dakatarwa). Sau da yawa, da quicklime ko lemun tsami ne ma ake magana a kai a matsayin alli oxide.

Calcium hydroxide, wanda aka kirkirar da abubuwan sunadarai zuwa ga wasu abubuwa, ana samun su ta hanyar hanyar wanke lemun tsami, wato, sakamakon hulɗar (maganin sinadarai) na oxyci da kuma ruwa. Ainihin haka, wannan aikin yana kama da wannan:

CaO + H2O = Ca (OH) 2

Sakamakon bayani mai ruwa-ruwa yana da wani nauyin alkaline na matsakaici. Kamar duk hankulan hydroxides, calcium hydroxide ya haɗu da:

1. Inorganic acid tare da samuwar salin ƙwayoyin salts

H2SO4 + Ca (OH) 2 = CaSO4 + 2H2 O

2. Kwayar carbon dioxide, wanda aka narkar da ruwa, don haka maganin ruwa mai sauri ya zama turbid a cikin iska, kuma an kafa wani tsabta mai tsabta mai sauƙi wanda shine carbonate carbonate

CO2 + Ca (OH) 2 = CaCO3 + H2O

3. Monoxide na Carbon lokacin da zafin jiki ya kai digiri 400 na Celsius

CO (t °) + Ca (OH) 2 = CaCO3 + H2

4. Tare da salts, sakamakon haka shine farin precipitate - calcium sulphate

Na2SO3 + Ca (OH) 2 = CaSO3 + 2OH

Yin amfani da man fetur hydroxide yana da mashahuri. Tabbatarwa, kowa ya san cewa ana bin lemun tsami tare da ganuwar gine-ginen, trunks na bishiyoyi, da kuma amfani da shi a matsayin ɓangaren turmi na turmi. An yi amfani da man fetur hydroxide a cikin ginin tun zamanin d ¯ a. Kuma a yanzu an haɗa shi a cikin filastar, yana samar da tubalin silicate da sintiri, abin da ya ƙunshi kusan su kamar mota. Babban bambanci shine a cikin hanyar shiri na waɗannan mafita.

Alli hydroxide ake amfani da su yi laushi zuwa tukuru ruwa, domin yi na Bleach, lemun tsami inorganic takin causticization na sodium carbonate, da kuma potassium. Har ila yau, wannan abu ne ba makawa ga Tanning a cikin yadi masana'antu, a shiri na daban-daban mahadi na alli da kuma ga neutralization na acidic mafita da kuma sharar ruwan ciki har da. A bisa tushensa, an samar da acid kwayoyin.

Calcium hydroxide ta samu aikace-aikacensa a masana'antun abinci, inda aka fi sani da abincin abinci Е526, wanda ake amfani dashi a matsayin mai kula da acidity, hardener da thickener. A cikin masana'antun sukari, an yi amfani dashi don yin watsi da molasses.

A cikin gwaje-gwaje da gwaje-gwajen gwaje-gwajen, ruwan lemun tsami yana nuna alamar ganowar carbon dioxide a yayin yaduwar sinadaran. Ana amfani da madara mai lemun tsami don bi da tsire-tsire don kula da cututtuka da kwari.
