Ndi sodium sulphide

Sulfide ndi sodium wochuluka (sodium wochuluka sulphide luso) ndi pawiri amene chimagwiritsidwa ntchito mu makampani. Choncho, mankhwala ntchito zitsulo, mankhwala, makampani kuwala ndi mafakitale ena. Sodium sulphide, makamaka ntchito popanga zamkati, utoto, mu processing chikopa. Mankhwala ntchito limatsogolera ena zitsulo sanali akakhala. Sodium sulfide ndi yofunika m'munda wa umagwirira mawunikidwe. Izo ntchito monga reagent mu njira zosiyanasiyana.

Sodium sulphide. Chilinganizo (Na2S)

The yachibadwa thupi boma la nkhani imatengedwa homogeneous misa, mmene mkulu-tilinazo, kapena timibulu hygroscopic. Thunthu opangidwa mu mawonekedwe a monolith 3 makhalidwe mawonekedwe particulate (mu mawonekedwe a flakes kapena granules). Ikani analola mankhwala ndi kuwala bulauni, wotumbululuka chikasu kapena grayish mtundu. More kwambiri kapena mtundu wina uliwonse limasonyeza wothandizila kwambiri makutidwe ndi okosijeni. Chotero sulfide soda ndi wotaya katundu zothandiza zosafunika ntchito yeniyeni. The luso cholinga mankhwala lili kuchokera pa makumi asanu atatu makumi asanu ndi aŵiri zakuthupi m'munsi pansi chikhalidwe chimene kachigawo misa otsala insoluble si kuposa peresenti theka.

Mogwirizana ndi gulu la mlingo pachiswe Sodium anthu sulfurous anatumizidwa ku kalasi wachiwiri. thunthu ndi inflammable ndi zachiwawa. Pa nkhani imeneyi, ndi bwino kusunga zinthu mu zipinda chatsekedwa kuti zili ndi zipangizo zonse zofunikira kuti pakhale bata moto. Iwo ali osavomerezeka kuchotsa phukusi ndi mankhwala mpaka ntchito mwachindunji kwa thunthu. Pokhalabe kukhulupirika kwa sulfide muli ndi sodium zikhoza kusungidwa kwa zaka ziwiri. Mawu ogwira ntchito mu nkhani iyi ndi chaka chimodzi chokha.

Mayendedwe a mankhwala ayenera kuchitidwa mwa njira iliyonse zoyendera mu ngolo chatsekedwa kapena muli. chidwi ziperekedwe kwa potsegula ndi katundu chuma, makamaka ngati amaganiza mwachindunji kukhudzana ndi mankhwala, mmatumba mu muli ololera. Afotokoze kupewa kusunga zosakhalitsa m'madera lotseguka kapena omwetsera, wokonzeka bwino kuchita zimenezi.

Luso ndi sodium sulfide Chinese kupanga ali odzaza mu matumba wapadera makilogalamu twente-faifi. Kenaka umateteza makutidwe ndi okosijeni msanga komanso kukhudzana ndi kuwala. Komanso, monga ma CD ndi ng'oma zitsulo ntchito yokhayo yotumikira mankhwala, ndi makontena (CK-1-5 (7)), kapena muli ngati zofewa ntchito limodzi. mankhwala akhoza mmatumba mu matumba pepala (yachinai kapena zisanu wosanjikiza) ndi chamkati zapamadzi - thumba polyethylene. matumba mwina kulemera ukonde si makilogalamu oposa makumi asanu.

Ankanyamula mu muli wapadera mankhwala chimadzera kuti pomayenda katundu lotseguka mtundu.

Mankhwala kachulukidwe ndi 1,856 galamu pa centimeter kiyubiki. Kusungunuka kutentha ukufika madigiri 1180. mankhwala kwambiri hygroscopic. M'madzi pa madigiri makumi awiri kusungunuka 13,6% pa madigiri 97,5 - 45% zakuthupi. mankhwala amatha kupanga crystalline hydrates. Njira zothetsera amadzimadzi ndi sodium sulfide luso khalidwe anachita zamchere.

hydrolysis imachitidwa ndi sulphide ndi sodium komanso salt amene anapanga asidi ofooka ndi maziko amphamvu. Phenolphtalein mu mayeso chubu ndi yankho limakhala pinki. Izi zikusonyeza kuti sing'anga zamchere aumbike mu mayeso chubu. Choncho, sodium sulfide, komanso salt ena amene anapanga asidi ofooka ndi maziko amphamvu, hydrolysed kupanga chifukwa cha soda.
