二氯甲烷是一種有機物，為無色透明液體，具有類似醚的刺激性氣味。微溶于水，溶于乙醇和乙醚。是不可燃低沸點溶劑，常用來代替易燃的石油醚、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.

關于二氯甲烷產品的國際物流運輸：二氯甲烷用鍍鋅鐵桶、黑鐵桶或槽車密封包裝，其充裝容積為容器的80%，對有特殊要求的用戶可提供氮氣保護。

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.

出口操作中的難點：

Difficulties in export operation:

訂艙：危險品，因為是有毒物質，各個船公司對危險品都有著嚴格的要求和限制。能接有毒物質的船公司蠻多，但是哪條航線什么船公司能接能接包裝以哪種申報形式來做，都是有講究的，一個危險品代理是否，就要看是否熟悉危險品的選船和訂艙技巧。

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.

裝箱：氫氧化鉀廠家認為能操作危危險品資質的倉庫蠻多，但是由于此類產品低毒，攝入或吸入會導致眩暈，惡心，嘔吐等癥狀，所以該產品的裝箱作業禁止密閉操作，局部排風。操作人員必須經過專門培訓，嚴格遵守操作規程。

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.

建議操作人員佩戴自吸過濾式防塵口罩，戴化學防護眼鏡，穿聚乙烯防毒服，戴橡膠手套。遠離火種、熱源，工作場所嚴禁吸煙。遠離易燃、可燃物。避免產生粉塵。

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.

避免與還原劑接觸。搬運時要輕裝輕卸，防止包裝及容器損壞。該產品多為桶裝，一般建議打托，如果不打托的話，需要純人工操作，比較考驗裝箱工人的裝箱技巧。

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.
