sodium hydroxide

化學(xué)式為：NaOH，俗稱(chēng)燒堿、火堿、片堿、苛性鈉等，是一種高腐蝕性的強(qiáng)堿，是白色不透明的固體。有塊狀、片狀、粒狀和棒狀等。易溶于水，溶解時(shí)會(huì)放出大量的熱。易溶于水、乙醇以及甘油。燃燒時(shí)可能會(huì)產(chǎn)生有害的毒性煙霧

The chemical formula is NaOH, commonly known as caustic soda, caustic soda, flake alkali, caustic soda, etc. it is a kind of strong alkali with high corrosiveness and is a white opaque solid. There are massive, flaky, granular and rod-shaped. It is soluble in water and gives off a lot of heat when dissolved. Soluble in water, ethanol and glycerol. Harmful toxic smoke may be produced during combustion

氫氧化鈉對(duì)玻璃制品有輕微的腐蝕性，如果以玻璃容器長(zhǎng)時(shí)間盛裝熱的氫氧化鈉溶液，會(huì)造成玻璃容器損壞。

Sodium hydroxide is slightly corrosive to glass products. If the glass container is filled with hot sodium hydroxide solution for a long time, the glass container will be damaged.

氫氧化鈉有強(qiáng)烈刺激和腐蝕性。會(huì)刺激眼和呼吸道，腐蝕鼻中隔，皮膚和眼直接接觸會(huì)引起灼傷，誤服可造成消化道灼傷，黏膜糜爛、出血和休克。

Sodium hydroxide has strong irritation and corrosiveness. It can irritate the eyes and respiratory tract, corrode the nasal septum, cause burns in direct contact with skin and eyes, and cause digestive tract burns, mucosal erosion, bleeding and shock.

氫氧化鉀

Potassium hydroxide

化學(xué)式為KOH俗稱(chēng)苛性鉀，白色粉末或片狀固體，具有強(qiáng)堿性和腐蝕性。易吸收空氣中水分而潮解，吸收二氧化碳行成碳酸鉀。當(dāng)溶解于水、醇或用酸處理時(shí)產(chǎn)生大量熱量。有強(qiáng)的堿性和腐蝕性，其性質(zhì)與燒堿相似。中等毒，半數(shù)致死量(大鼠，經(jīng)口)1230mg/kg。

Chemical formula is Koh, commonly known as caustic potassium, white powder or flake solid, with strong alkaline and corrosive. Easy to absorb moisture in the air and deliquescence, absorption of carbon dioxide line into potassium carbonate. When dissolved in water, alcohol or treated with acid, a large amount of heat is generated. It has strong alkalinity and corrosiveness, and its properties are similar to caustic soda. The median lethal dose (rat, oral) was 1230mg / kg.

由于氫氧化物對(duì)碳水化合物的分解作用，而使其相對(duì)于酸腐蝕的危險(xiǎn)更加嚴(yán)重，經(jīng)氫氧化鉀腐蝕的皮膚，通常呈現(xiàn)深度灼傷，且難以愈合，一旦眼睛或皮膚接觸到氫氧化鉀，應(yīng)迅速將受傷部位以水不斷沖洗15分鐘以上，并立即就醫(yī)；口服會(huì)灼傷消化道，致命。

Due to the decomposition effect of hydroxide on carbohydrates, it is more dangerous than acid corrosion. The skin corroded by potassium hydroxide usually shows deep burns and is difficult to heal. Once eyes or skin contact with potassium hydroxide, the injured part should be washed with water for more than 15 minutes and immediately seek medical advice; If taken orally, it burns the digestive tract and is fatal.

儲(chǔ)存注意事項(xiàng)：應(yīng)儲(chǔ)存于陰涼、干燥、通風(fēng)良好的庫(kù)房；遠(yuǎn)離火種、熱源；應(yīng)與易（可）燃物、酸類(lèi)等分開(kāi)存放。

Storage precautions: store in a cool, dry and well ventilated warehouse; Keep away from fire and heat source; It should be stored separately from inflammables and acids.
