Eli nqaku liza kunika inkcazo ecacileyo yezinto eziphathekayo kunye neekhemikhali ze-sodium hydrosulfide, ukuhlolwa kweengozi zayo, amanyathelo oncedo lokuqala, amanyathelo okulwa nomlilo, impendulo engxamisekileyo yokuvuza, ukuphatha nokusebenza kunye nokugcinwa, ukulawulwa kokuvezwa / ukukhuselwa komntu, iimpawu ze-physicochemical, ukuzinza kunye ne-reactivity, idatha ye-toxicological, i-ecological order, i-ecological order, idatha ye-ecological, idatha ye-ecological, i-regulatory in information, i-dispotory in information, i-dispotory in information, i-dispotory in information, i-dispotory, i-dispotory kunye nokuqinisekisa ukukhuselwa kolwazi. ukuthembeka.

I. IiPropati zePhysical and Chemical

I-sodium hydrosulfide yi-crystalline powder emhlophe ene-alkalinity enamandla kunye neempawu zokunciphisa. Ifomula yayo yemolekyuli yiNaHS, kwaye ubunzima bayo bemolekyuli yi-56.06. Indawo yokunyibilika yi-100°C, kwaye indawo yokubila yi-140°C. I-sodium hydrosulfide inyibilika ngokulula emanzini, ivelisa i-sodium hydroxide kunye ne-hydrogen sulfide.

II. Isishwankathelo seeNgozi

Isodium hydrosulfide icaphukisa kakhulu amehlo, ulusu kunye nenwebu. Ukuphefumla umphunga wayo kunokubangela iimpawu zokucaphuka kokuphefumla. Ukungeniswa kunokukhokelela ekutshisweni kwesisu, ukukhukuliseka kwe-mucosal, ukopha, kunye nokothuka. Ukongeza, i-sodium hydrosulfide iphendula kunye ne-acids ukukhulula igesi evuthayo ye-hydrogen sulfide kwaye isabela ngobundlobongela kunye ne-oxidizers kunye nezinto ezine-acidic.

III. Amanyathelo oNcedo lokuQala

Kwimeko yokunxibelelana kwesikhumba, susa ngokukhawuleza iimpahla ezingcolileyo kwaye uhlambulule indawo echaphazelekayo ngamanzi amaninzi ahambayo ubuncinane imizuzu eyi-15. Ukudibana kwamehlo, phakamisa ngokukhawuleza iinkophe kwaye uhlambulule ngokucokisekileyo ngamanzi amaninzi ahambayo okanye i-saline ubuncinane imizuzu eyi-15. Ukuba urholile, hambisa isigulana kumoya omtsha kwaye uqinisekise ukuba indlela yomoya icacile. Kwimeko yokungeniswa, hlambulula umlomo, unike ubisi okanye amaqanda abamhlophe, kwaye ufune unyango ngokukhawuleza.

IV. Amanyathelo okulwa nomlilo

Isodium hydrosulfide kufuneka igcinwe kwindawo epholileyo ezinikeleyo, engena umoya kakuhle, kude nemithombo yomlilo kunye nobushushu. Kufuneka igcinwe ngokwahlukileyo kwi-oxidizers kunye ne-acids, kwaye ukuxuba kunqatshelwe ngokungqongqo. Ukuxhobisa indawo yokugcina kunye neentlobo ezifanelekileyo kunye nobuninzi bezixhobo zokulwa nomlilo kunye nezixhobo zokuphendula ngokukhawuleza ukuvuza. Indawo yokugcina kufuneka ibe nezinto ezifanelekileyo zokuqulatha nakuphi na ukuvuza.

V. Iimpendulo eziNgxamisekileyo kwindawo ezivuzayo

Beka bucala indawo evuzayo kwaye uthintele ukufikelela. Abaphenduli bexesha likaxakeka bayacetyiswa ukuba banxibe iimaski zothuli (ubuso obugcweleyo) kunye nempahla ekhuselayo ye-asidi-alkali. Ukudibana nezikhongozeli ezophukileyo kunye nezinto ezivuzayo akuvumelekanga de kunxitywe iimpahla ezifanelekileyo zokukhusela. Sika umthombo ovuzayo ukuba kunokwenzeka. Ukuvuza okuncinci: kunqande ukuvelisa uthuli kwaye usebenzise ifotsholo ecocekileyo ukuqokelela imathiriyeli kwisitya esomileyo, esicocekileyo nesigqunyiweyo. Ukuvuza okukhulu: gubungela ngeplastiki okanye i-canvas. Emva koko uqokelele kwaye usetyenziswe ngokutsha okanye uthuthelwe kwindawo yokulahla inkunkuma ukuze ufumane unyango.

VI. UkuPhathwa kokuSebenza kunye noGcino

Izilumkiso zokuSebenza: Yenza imisebenzi kwindawo evaliweyo kwaye unike umoya owaneleyo wendawo yokukhupha umoya. Thintela uthuli ekukhutshweni emoyeni weworkshop. Abanini-zithuthi kufuneka bafumane uqeqesho olukhethekileyo kwaye babambelele ngokungqongqo kwiinkqubo zokusebenza. Kucetyiswa ukuba abaqhubi banxibe iimaski zothuli (ubuso obugcweleyo), iimpahla zerabha ezinokumelana ne-asidi-alkali, kunye neeglavu ezixhathisa i-asidi-alkali. Zigcine kude nemithombo yomlilo nobushushu; ukutshaya akuvumelekanga emsebenzini. Sebenzisa izixhobo zokungenisa umoya ezingagqabhukiyo kunye nezixhobo. Gwema ukuvelisa uthuli kunye noqhagamshelwano kunye ne-oxidizers kunye ne-acids. Ukunyamekela okukhethekileyo kufuneka kuthathwe ukuphepha ukudibanisa namanzi. Ukuxhobisa indawo ngeentlobo ezifanelekileyo kunye nobuninzi bezixhobo zokulwa nomlilo kunye nezixhobo zokuphendula ngokukhawuleza ezivuzayo. Izikhongozeli ezingenanto zinokugcina iintsalela eziyingozi.

Izilumkiso zokuGcina: Gcina kwindawo yokugcina impahla epholileyo, enempepho eyaneleyo, kude nemithombo yomlilo nobushushu. Thintela ukukhanya kwelanga ngqo. Gcina ngokwahlukileyo kwi-oxidizers kunye ne-acids, kwaye ukuxuba kunqatshelwe ngokungqongqo. Ukuxhobisa indawo yokugcina kunye neentlobo ezifanelekileyo kunye nobuninzi bezixhobo zokucima umlilo. Indawo yokugcina kufuneka ibe nezinto ezifanelekileyo zokuqulatha nakuphi na ukuvuza.

VII. Ulawulo lokutyhileka / uKhuseleko lomntu

Umda wokuvezwa emsebenzini: I-China MAC (mg/m3): Akukho mgangatho usekiweyo. Owayesakuba yiSoviet Union MAC (mg/m3): Akukho mgangatho usekiweyo. TLVTN: Akukho mgangatho usekiweyo. TLVWN: Akukho mgangatho usekiweyo. Indlela yokubeka iliso: Ulawulo lobunjineli: Ukusebenza okuvaliweyo, ukubonelela ngokukhupha okwaneleyo kwendawo. Ukukhuselwa kwenkqubo yokuphefumla: Xa ugxininiso emoyeni lugqithise umgangatho, kufuneka kunxitywe imaski yothuli lwe-self-priming filter. Xa uhlangula okanye uphuma kwindawo engxamisekileyo, kufuneka kunxitywe isixhobo sokuphefumla. Ukukhuselwa kwamehlo: Nxiba iiglasi zokhuseleko lwekhemikhali. Ukhuseleko lomzimba: Nxiba iasidi yerabha kunye nempahla ekwaziyo ukumelana ne-alkali. Ukukhuselwa kwesandla: Nxiba i-asidi yerabha kunye neeglavu ezixhathisa ialkali. Olunye ukhuseleko: Ukutshaya, ukutya nokusela akuvumelekanga emsebenzini, nokuhlamba izandla ngaphambi kokutya. Emva komsebenzi, hlamba kwaye utshintshe iimpahla. Gcina imikhwa elungileyo yococeko.
