Nā kikoʻī kikoʻī no ka mālama ʻana a me ka lawe ʻana no ka sodium Hydrosulfide

Palekana mālama a me ka halihali kiko'ī o Sodium Hydrosulfide ma ke kahua o ka hana kemika i na mea maka

Hōʻuluʻulu Manaʻo

ʻO ka sodium hydrosulfide, ma ke ʻano he mea hana kemika maʻamau, loaʻa ka alkalinity ikaika a me ka hōʻemi ʻana i nā waiwai, pono e mālama pono i nā lula palekana i ka wā o ka mālama ʻana a me ka lawe ʻana. E hāʻawi kēia ʻatikala i kahi kikoʻī kikoʻī o nā waiwai kino a me nā kemika o ka sodium hydrosulfide, kahi loiloi o kona mau pōʻino, nā hana kōkua mua, nā hana kaua ahi, ka pane ʻana i ka pilikia i nā leaks, ka mālama ʻana a me ka mālama ʻana, ka mālama ʻana / pale pilikino, nā hiʻohiʻona physicochemical, kūpaʻa a me ka reactivity.

I. Na Waiwai Kino a Kimia

ʻO ka sodium hydrosulfide kahi pauka keʻokeʻo keʻokeʻo me ka alkalinity ikaika a me nā waiwai hoʻemi. ʻO kāna kumu molekala ʻo NaHS, a ʻo kona kaumaha molekala he 56.06. ʻO ka helu hoʻoheheʻe he 100°C, a ʻo ka helu hoʻolapalapa he 140°C. Hiki ke hoʻoheheʻe ʻia ka sodium hydrosulfide i ka wai, e hana ana i ka sodium hydroxide a me ka hydrogen sulfide.

II. Nānā nui o nā pōʻino

ʻO ka sodium hydrosulfide ka mea hoʻonāukiuki nui i ka maka, ka ʻili, a me nā membrane mucous. Hiki i ka inhalation o kona mau mahu ke kumu o ka hanu hanu. Hiki i ka ʻai ʻana ke alakaʻi i ke kuni ʻana o ka ʻōpū, ka ʻāʻī ʻana o ka mucosal, ke koko, a me ka haʻalulu. Hoʻohui ʻia, hoʻololi ka sodium hydrosulfide me nā waikawa e hoʻokuʻu i ke kinoea hydrogen sulfide flammable a hana ikaika me nā mea oxidizer a me nā mea waikawa.

III. Na Hana Kokua Mua

Inā pili ka ʻili, wehe koke i nā lole i haumia a holoi i ka wahi i hoʻopili ʻia me ka wai kahe nui no 15 mau minuke. No ka nānā maka, e hāpai koke i nā lihilihi a holoi pono me ka nui o ka wai kahe a i ʻole ka paʻakai no 15 mau minuke. Inā inhaled, e hoʻoneʻe i ka mea maʻi i ka ea hou a hōʻoia i ka maʻemaʻe o ke ea. I ka ʻai ʻana, holoi i ka waha, hāʻawi i ka waiū a i ʻole nā ​​hua keʻokeʻo, a e ʻimi koke i ka lāʻau lapaʻau.

IV. Na Hana Puhi Ahi

Pono e mālama ʻia ka sodium hydrosulfide i loko o kahi hale kūʻai i hoʻolaʻa ʻia i hoʻoluʻu maikaʻi ʻia, ma kahi o nā kumu o ka ʻā a me ka wela. Pono e mālama kaʻawale ʻia mai nā oxidizers a me nā waikawa, a pāpā loa ʻia ka hui ʻana. E hoʻolako i kahi e waiho ai me nā ʻano kūpono a me ka nui o nā mea hana ahi a me nā mea hoʻopuka pilikia. Pono e loaʻa nā mea kūpono i ka wahi e mālama ai i nā lepa.

V. Pane ulia pōpilikia i ka Leak

E hoʻokaʻawale i ka wahi leak i hoʻohaumia a hoʻopaʻa i ke komo ʻana. Paipai ʻia ka poʻe pane ulia pōpilikia e ʻaʻahu i nā maka lepo (ke alo piha) a me nā lole pale acid-alkali. ʻAʻole ʻae ʻia ka hoʻopili ʻana me nā ipu haʻihaʻi a me nā mea leki a hiki i ke komo ʻana i nā lole pale kūpono. E ʻoki i ke kumu leak inā hiki. No nā liʻiliʻi liʻiliʻi: e pale i ka hana lepo a hoʻohana i kahi ʻōpala maʻemaʻe e hōʻiliʻili i ka mea i loko o kahi pahu maloʻo, maʻemaʻe, uhi ʻia. No nā leaks nui: uhi ʻia me ka ʻili pepa a i ʻole ke kāwele. A laila e hōʻiliʻili a hana hou a lawe ʻia paha i kahi kahua hoʻolei ʻōpala no ka mālama ʻana.

VI. ʻO ka lawelawe ʻana a me ka mālama ʻana

ʻO ka mālama ʻana i ka hana: E hana i nā hana i loko o kahi wahi paʻa a hāʻawi i ka ea hoʻoheheʻe kūloko. Kāohi i ka lepo mai ka hoʻokuʻu ʻia ʻana i ka ea hale hana. Pono nā mea hana e hoʻomaʻamaʻa kūikawā a mālama pono i nā kaʻina hana. Manaʻo ʻia e hoʻohana nā mea hoʻohana i nā pale huna lepo (ke alo piha), ka lole pale waika-alkali, a me nā mīkina lima kūpaʻa waika-alkali. E hoʻokaʻawale i nā kumu o ke ahi a me ka wela; kapu ka puhi paka ma kahi hana. E hoʻohana i nā ʻōnaehana hoʻoheheʻe pahū a me nā mea hana. Hōʻalo i ka hoʻoulu ʻana o ka lepo a me ka hoʻopili ʻana me nā oxidizer a me nā waikawa. Pono e mālama pono e pale i ka pili ʻana me ka wai. E hoʻolako i ka wahi me nā ʻano kūpono a me ka nui o nā lako hana ahi a me nā mea hoʻokele ulia pōpilikia. Hiki ke mālama ʻia nā koena ʻino i nā ipu ʻole.

E mālama i ka mālama ʻana: E kūʻai i loko o kahi hale kūʻai i hoʻolaʻa ʻia i hoʻoluʻu maikaʻi ʻia, ma kahi mamao o nā kumu hoʻā a me ka wela. Kāohi i ka ʻike ʻana o ka lā. E kūʻai kaʻawale mai nā oxidizer a me nā waikawa, a pāpā loa ʻia ka hui ʻana. E hoʻolako i kahi e waiho ai me nā ʻano kūpono a me ka nui o nā mea hana ahi. Pono e loaʻa nā mea kūpono i ka wahi e mālama ai i nā lepa.

VII. Ka Mana Hōʻikeʻike / Palekana pilikino

Ka palena hoʻolaha ʻoihana: Kina MAC (mg/m3): ʻAʻohe mea maʻamau i hoʻokumu ʻia. ʻO ka Soviet Union MAC mua (mg/m3): ʻAʻohe mea i hoʻokumu ʻia. TLVTN: ʻAʻohe maʻamau i hoʻokumu ʻia. TLVWN: ʻAʻohe kūlana i hoʻokumu ʻia. Ke ʻano o ka nānā ʻana: Ka hoʻokele ʻenekinia: Paʻa ka hana, hāʻawi i ka pauku kūloko. Ka pale ʻana i ka ʻōnaehana hanu: Ke ʻoi aku ka nui o ka ʻike ma ka lewa ma mua o ka maʻamau, pono e hoʻohana ʻia kahi huna huna huna huna huna. I ka hoʻopakele ʻana a i ʻole ka haʻalele ʻana i kahi pilikia, pono e hoʻohana i kahi respirator ea. Pale maka: E hoʻohana i nā makaaniani palekana kemika. Palekana kino: E ʻaʻahu i ka ʻaʻahu waika a me nā lole kūpaʻa alkali. Pale lima: E hoʻohana i nā mīkina lima kūʻē i ka ʻakika. ʻO nā pale ʻē aʻe: Ua pāpā ʻia ka puhi ʻana, ka ʻai ʻana a me ka inu ʻana ma kahi hana, a holoi lima ma mua o ka ʻai ʻana. Ma hope o ka hana, e ʻauʻau a hoʻololi i nā lole. E mālama i nā ʻano maʻemaʻe maikaʻi.

VIII. Na Waiwai Kinohi

Nā hiʻohiʻona a me nā waiwai: ʻO ke keʻokeʻo a hiki i ka pauka crystalline kala ʻole a i ʻole nā ​​kristal flaky me ke ʻala o ka hydrogen sulfide. Ka helu heheʻe (℃): ʻoi aku ka nui ma mua o 100 Ka mānoanoa pili (wai = 1): 1.79 Solubility: hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o ka methanol a me nā mea hoʻoheheʻe ʻokoʻa ʻē aʻe. Hoʻohana nui: hoʻohana ʻia e like me nā reagents analytical, a me nā mea ʻē aʻe. Nā kūlana e pale aku i ka pilina: ea humid. ʻO ka pōʻino polymerization: ʻaʻohe polymerization Nā huahana decomposition: hydrogen sulfide, sulfur oxides.

IX. Paʻa a me ka hana hou

Paʻa: Paʻa Ka pilikia Polymerization: ʻAʻohe polymerization Nā ʻano e pale aku ai: Heat Nā mea like ʻole: ʻAka ikaika, oxidizer ikaika Nā huahana hoʻoheheʻe weliweli: Hydrogen sulfide Huahana (decomposition) nā huahana: Hydrogen sulfide, sulfur oxide Ka hoʻokaʻawale ʻana i nā mea ʻawaʻawa Acute toxicity Acute toxicity Oral-rat LD50/kg Irab-rat LD560: 500 mg Irabbit/kg hola Huhū nui Ka ʻili-rabbit 24 mg/500 hola Huhū nui Inhalation-iole TCLo: 24ppm/1400 hola ʻO nā hiʻohiʻona pōʻino Hoʻopili me ka waikawa e hoʻokuʻu i ke kinoea hydrogen sulfide flammable. Hiki iā ia ke hana ikaika me nā oxidants e hoʻopau i ka puhi ahi a pahū paha.
