二氯甲烷是一种有机物，为无色透明液体，具有类似醚的刺激性气味。微溶于水，溶于乙醇和乙醚。是不可燃低沸点溶剂，常用来代替易燃的石油醚、乙醚等。

Dichloromethane is an organic substance, a colorless transparent liquid with an irritating smell similar to ether. Slightly soluble in water, soluble in ethanol and ether. It is a nonflammable solvent with low boiling point, which is often used to replace flammable petroleum ether, ether, etc.

关于二氯甲烷产品的国际物流运输：二氯甲烷用镀锌铁桶、黑铁桶或槽车密封包装，其充装容积为容器的80%，对有特殊要求的用户可提供氮气保护。

International logistics and transportation of dichloromethane products: dichloromethane is sealed and packed in galvanized iron drums, black iron drums or tank cars, with a filling volume of 80% of the container. Nitrogen protection can be provided for users with special requirements.

出口操作中的难点：

Difficulties in export operation:

订舱：危险品，因为是有毒物质，各个船公司对危险品都有着严格的要求和限制。能接有毒物质的船公司蛮多，但是哪条航线什么船公司能接能接包装以哪种申报形式来做，都是有讲究的，一个危险品代理是否，就要看是否熟悉危险品的选船和订舱技巧。

Booking: dangerous goods. Because they are toxic substances, all shipping companies have strict requirements and restrictions on dangerous goods. There are many shipping companies that can receive toxic substances. However, there are different ways of declaration for which shipping lines and shipping companies can receive and receive packaging. Whether a dangerous goods agent is professional depends on whether he is familiar with the ship selection and space booking skills of dangerous goods.

装箱：氢氧化钾厂家认为能操作危危险品资质的仓库蛮多，但是由于此类产品低毒，摄入或吸入会导致眩晕，恶心，呕吐等症状，所以该产品的装箱作业禁止密闭操作，局部排风。操作人员必须经过专门培训，严格遵守操作规程。

Packing: the potassium hydroxide manufacturer thinks that there are many warehouses qualified to operate dangerous goods. However, due to the low toxicity of such products, ingestion or inhalation will lead to dizziness, nausea, vomiting and other symptoms, so the packing operation of this product is forbidden to be closed and local ventilation is allowed. Operators must receive special training and strictly abide by the operating procedures.

建议操作人员佩戴自吸过滤式防尘口罩，戴化学防护眼镜，穿聚乙烯防毒服，戴橡胶手套。远离火种、热源，工作场所严禁吸烟。远离易燃、可燃物。避免产生粉尘。

It is recommended that operators wear self-priming filter type dust mask, chemical safety glasses, polyethylene gas protective clothing and rubber gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Keep away from inflammables and combustibles. Avoid dust generation.

避免与还原剂接触。搬运时要轻装轻卸，防止包装及容器损坏。该产品多为桶装，一般建议打托，如果不打托的话，需要纯人工操作，比较考验装箱工人的装箱技巧。

Avoid contact with reducing agent. Handle with care to prevent damage to the package and container. This product is mostly packaged in barrels. It is generally recommended to use pallets. If not, it needs pure manual operation to test the packing skills of packing workers.
