Description

TECHNICAL FIELD

[0001] The utility model relates to plasticizer technical field, specifically for a kind of filter device for plasticizer. BACKGROUND

[0002] Plasticizer, also known as plasticizing agent, is a kind of high molecular material additive, which is widely used in various fields such as plastics, rubber, adhesive, cellulose, resin, medical devices and cable. Its main function is to increase the softness, plasticity and processing performance of materials. Plasticizer refers to a substance added to plastic to increase its plasticity. By weakening the intermolecular forces of the polymer, the mobility of the polymer chains is increased, thereby reducing the crystallinity of the polymer chains, making the product flexible.

[0003] There are many types of plasticizers, but most of them are viscous liquids. Some plasticizers need to be filtered for internal impurities and foreign matter during use. The existing filter plates are used directly for filtering, and the plasticizer cannot be dispersed during the filtering process. The flow effect of the more viscous plasticizer is poor, which causes some plasticizers to accumulate together, thereby affecting the filtering effect of the filter device on the plasticizer.

[0004] At the same time, the existing part of the filter device does not have a structure for disturbing the plasticizer on the surface of the filter plate during use. The plasticizer is relatively viscous, which causes the plasticizer to gradually block the filter plate. This not only reduces the filtering effect of the plasticizer, but also affects the normal use of the filter plate, reducing the applicability of the filter device. UTILITY MODEL CONTENT
