順酐結(jié)塊兒了,會影響使用嗎?
順酐廠家認(rèn)為其結(jié)塊是由于吸收空氣中水分還原成酸的原因,順酐吸潮造成的，變色是由于雙鍵被氧化的緣故,可以重結(jié)晶繼續(xù)，短時間內(nèi)不會影響使用。
Does the agglomeration of maleic anhydride affect its use? The manufacturer of maleic anhydride believes that its agglomeration is caused by the absorption of moisture in the air to reduce to acid, and the moisture absorption of maleic anhydride is caused by the oxidation of double bonds, which can be recrystallized and will not affect its use in a short period of time.
怎么解決這個事兒呢？您可以嘗試將其放在干燥通風(fēng)處，結(jié)塊的已經(jīng)吸水變質(zhì)了（反應(yīng)成有機(jī)酸了），建議過篩后廢棄。
How can we solve this problem? You can try placing it in a dry and ventilated place. The clumps have already absorbed water and deteriorated (reacting into organic acids). It is recommended to discard them after sieving.
此外要注意一些事項，比如：
In addition, some precautions should be taken, such as:
由于順酐本身是一種易燃易爆的化學(xué)品，并且還具有一定的腐蝕性，長期接觸會對人體造成損傷，如人體吸入含有順酐的空氣后，會出現(xiàn)咳嗽、淌眼淚、打噴嚏等癥狀，嚴(yán)重時，甚會使呼吸變得困難，若是皮膚與順酐接觸，則會產(chǎn)生紅腫、疼痛的情況。
Due to the fact that maleic anhydride is a flammable and explosive chemical and has a certain degree of corrosiveness, long-term exposure can cause damage to the human body. For example, after inhaling air containing maleic anhydride, the human body may experience symptoms such as coughing, tearing, and sneezing. In severe cases, it may even make breathing difficult. If the skin comes into contact with maleic anhydride, it can cause redness, swelling, and pain.
鑒于此，應(yīng)當(dāng)在順酐過程中，采取有效的控制措施，確保。在順酐時，一旦發(fā)生跑冒滴漏等情況，必須由專人進(jìn)行處理，在處理的過程中，要配戴防護(hù)用具。
In view of this, effective control measures should be taken in the production process of maleic anhydride to ensure safety. During the production of maleic anhydride, if there is any leakage or leakage, it must be handled by a dedicated person, and protective equipment must be worn during the treatment process.
尤其是貯罐及裝置出現(xiàn)泄漏時，應(yīng)在時間查明原因，采取有效的方法和措施進(jìn)行緊急處理，避免順酐大量泄漏，出來的順酐產(chǎn)品在儲存時，應(yīng)置于通風(fēng)條件良好的庫房當(dāng)中，并保證庫房內(nèi)保持常溫，貯罐應(yīng)當(dāng)進(jìn)行可靠接地，采取靜電屏蔽措施。
Especially when there is leakage in storage tanks and devices, the cause should be identified as soon as possible, and effective methods and measures should be taken for emergency treatment to avoid a large amount of leakage of maleic anhydride. The produced maleic anhydride products should be stored in a well ventilated warehouse and ensure that the warehouse is kept at room temperature. The storage tanks should be reliably grounded and electrostatic shielding measures should be taken.
在對順酐進(jìn)行運輸時，應(yīng)當(dāng)做好防水防潮工作，并且不得暴露在陽光下，以免順酐升華，要做到輕拿輕放；如果順酐起火，不得使用干粉滅火器，而是應(yīng)當(dāng)選用二氧化碳滅火器。更多相關(guān)內(nèi)容就來我們網(wǎng)站

When transporting maleic anhydride, waterproof and moisture-proof measures should be taken, and it should not be exposed to sunlight to avoid sublimation of maleic anhydride. It should be handled with care; If maleic anhydride catches fire, dry powder fire extinguishers should not be used, but carbon dioxide fire extinguishers should be used.
