Description

PVC cross-linking agent raw and other materials production is with adding device

Technical Field

The utility model belongs to the technical field of cross-linking agent production facility, concretely relates to PVC cross-linking agent raw and other materials production is with adding device.

Background

The cross-linking agent is also called bridging agent, and is an important component of the polyhydrocarbon photoresist, and the photochemical curing action of the photoresist depends on the cross-linking agent with double photosensitive functional groups to participate in reaction, and after the cross-linking agent is exposed, the cross-linking agent generates double free radicals, which react with the polyhydrocarbon resin to form bridge bonds between polymer molecular chains and become insoluble substances with three-dimensional structures.

Crosslinking agents are mainly used in high molecular materials such as rubbers and thermosetting resins. Because the molecular structure of the high molecular material is like a long line, the high molecular material has low strength when not crosslinked, is easy to break and has no elasticity, the crosslinking agent has the function of generating chemical bonds among linear molecules to connect the linear molecules together to form a net structure, so that the strength and the elasticity of the rubber are improved, and the crosslinking agent used in the rubber is mainly sulfur and is added with an accelerator. When the accelerant is used together with a catalyst or a fixing agent, a substance with a small dosage can improve the reaction rate, the accelerant is in the form of white powder, the white powder is heated to 200 ℃ to sublimate, the white powder can be ignited by naked fire at normal temperature, and is insoluble in ether, aromatic hydrocarbon and the like, when the accelerant and the crosslinking agent are used, the accelerant and the crosslinking agent cannot be simultaneously placed into resin, combustion or explosion accidents can occur, the accelerant must be added firstly, the crosslinking agent is added after the accelerant and the resin are fully stirred, otherwise, the resin can be fixed in advance, resin materials are wasted, in the adding process of the existing crosslinking agent and other raw materials, operators firstly need to weigh and proportion the crosslinking agent and the accelerant, and then respectively pour the crosslinking agent and the accelerant into a stirring tank, and the defects exist: in the using process of the cross-linking agent and the accelerator, operators often weigh the cross-linking agent and the accelerator according to the proportion according to experience, certain errors exist, and the problem that the existing cross-linking agent and the accelerator are not weighed accurately in the adding process exists.
