Sodium nitrate - ma'auransa, kuma maƙiyi

Kowannen mu ne gwani a aikin noma, kuma mun san da ake dangantawa da shi. Kowa ya sani game da nitrates, game da amfani da illolin. Kuma a gaskiya, abin da sodium nitrate?

Da dabara na wannan abu NaNO3, da sauran sunan - sodium nitrate. A bayyanar shi ne wani fari crystalline abu, wani lokacin ciwon grayish ko yellowish tint. The ruwa dissolves da kyau. A dandano ne m-m. Yana faruwa ta halitta a matsayin ma'adinai - Chilean nitrate. Nitrate hygroscopic, narkewa maki 308 ° C, da fadada (tafasar) - 380 °. Strong oxidant, a reflux sake oxygen.

Nuna sodium nitrate ammonia kira daga nitrogen, ko iska. Akwai sauran fasaha na nitrate dogara ne a kan hulda da daban-daban da kuma halayen bazuwar. iri:

- A - domin amfani a cikin juyi a lokacin da soldering da waldi da karafa.

- B - for etching karafa da kuma gami bayani.

Store sodium nitrate dole ne cushe a multiwall bags. Isar iya zama wani Hanyar wasu fiye da iska, domin kai da kuma saukewa ba za a iya gauraye da kwayoyin abubuwa domin su hana ƙonewa.

Kamar yadda shi ne ake kira, sodium nitrate ne yadu amfani a fannoni daban daban na masana'antu da kuma aikin noma. A noma aka yi amfani da matsayin da nitrogen taki a kan duk iri kasa karkashin kayan amfanin gona (dankali, beets), da 'ya'yan itace da Berry plantations. Tun nitrate ne wani alkaline taki view, shi ne mafi alhẽri amfani a acidic kasa. Kamar yadda taki amfani da ƙasa a cikin bazara, za a iya amfani da taki. A tabbatacce sakamako a kan shuka yana ba kawai nitrogen amma kuma sodium.

A masana'antu, da yin amfani da sodium nitrate kamar:

- bangaren bayani ga etching bakin shambura.

- ulla ɓangare na man shafawa a kan mirgina Mills na bakin shambura.

- wani clarifier tare da gilashi tafasar.

- wani oxidizer a roka man fetur.

- gishiri bangaren refrigerants.

A cikin masana'antun sarrafa kayayyakin abinci nitrate amfani da matsayin hana aifuwa na maza - E251. Akwai ambaci cewa a 1397 nitrate aka yi amfani da su a tanadin kifi. Wannan shi ne saboda tasirin nitrite kafa daga nitrate kwayoyin. Nitrate da ake amfani da:

- tare da cuku yi.

- sayen nama. Nitrates a ƙarƙashin rinjayar kwayoyin tuba zuwa nitrites, wanda da m sakamako a kan kayayyakin, a lokaci guda ba su da ya dace haske launi.

Nitrates kuma za a iya amfani da wani bayani. Nama shafa gishiri cakuda, nitrate, sugars da kuma sanya karkashin Yoke. A resultant bayani da aka rufe da nama.

Nitrate matsayin oxidizing wakili ne a yi amfani da pyrotechnic qagaggun. A cikin irin wannan qagaggun, ta nufi - don samar da oxygen konewa tsari.

Nitrate da ake amfani a magani a matsayin vasodilator. Bugu da ƙari kuma, shi sauqaqa hanji spasms, hidima a matsayin cyanide guba maganin guba da kuma matsayin laxative.

A lokaci guda nitrate a dabbobi masu shayarwa an dauke da wani mai guba abu. A wani sashi na 180 MG / kg jiki nauyi na gwada berayen mutu rabin. Lokacin da E251 tsunduma a gudanar da bincike, an gano cewa, dumama zuwa da zazzabi sama 120 ° C take kaiwa ga samuwar na Carcinogens.

Nazarin gudanar da World Health Organization, shi zai yiwu domin sanin halal kullum kashi na nitrates zuwa 3.7 milligrams da kilogram na jiki nauyi. A wadannan na faruwa - a lokacin da nitrates ne a cikin manyan hanji, a karkashin mataki na kananan kwayoyin halitta, suna tuba zuwa nitrites, kuma na karshe, samun shiga cikin jini, haemoglobin yana tuba zuwa methemoglobin, wanda ba zai iya kawo oxygen.

The biyayya dauke sodium nitrate. Abin da shi ne inda rarraba a cikin yanayi, kamar yadda shi dai, da kuma inda zartar a cikin masana'antu. Yana bayyana ta sakamako a kan jikin mutum.
