A kind of packaging container of ethylene glycol antimony

Abstract

The invention relates to a packaging container, in particular to a packaging container of ethylene glycol antimony. An upper opening of a packaging barrel (19) internally containing ethylene glycol antimony (27) is provided with a barrel cover (21), a protrusive pipe (22) is arranged in the middle of the upper face of the barrel cover, an internal thread (10) and an external thread (11) are arranged on the inner wall and the outer wall of the protrusive pipe (22) respectively, a reducing external thread is arranged on the lower portion of an upper plate (8) of a movable seal cover, an upper external thread of the movable seal cover is connected with the internal thread arranged on the barrel cover at the bottom of the protrusive pipe, a screwing plate (7) is arranged on the upper face of the upper plate of the movable seal cover, a big-end-up radial vertical plate (9) is arranged on the lower portion of the upper plate of the movable seal cover, and an internal thread of a pipe cover (24) is connected with the external thread of the protrusive pipe; or the internal thread of the protrusive pipe is connected with an external thread of an opening of a bottle (1). The structure of the barrel cover of the packaging barrel is used for cooperating with the assistant bottle, dampproofness is ensured when ethylene glycol antimony is taken out, and the defect that in the prior art ethylene glycol antimony is affected with damp easily is overcome.

Description

technical field [0001] The invention relates to a packing container, in particular to a packing container of ethylene glycol antimony. Background technique [0002] It is known that ethylene glycol antimony is currently used as an additive for plastic products. Since ethylene glycol antimony has a better catalytic effect, it has a higher solubility in ethylene glycol solution than the catalyst antimony trioxide and antimony acetate. , good dispersion. The antimony content is high, the activity is good, and the production capacity of the device can be improved. Moreover, as a catalyst, ethylene glycol antimony itself will not bring in new impurities, which can improve the internal quality of the slices and improve the spinnability after processing; the main component of plastic bottles used in the processing and production of beverages and edible oils is polyester. During the production and preparation of polyester, a catalyst is needed. In the past, antimony-based catalys...

Problems solved by technology

However, the disadvantage of ethylene glycol antimony is that it decomposes in humid air, and the damp ethylene glycol antimony will change the performance of the later use and reduce the product quality; most of the existing ethylene glycol antimony packages are barrel containers. If the container is not tightly sealed, agglomeration will occur, especially in the production workshop in the southern rainy season, when there is a problem of humidity, it will lead to agglomeration of ethylene glycol antimony. This problem has not yet been overcome
