Structure of wollastonite and selection of modifier

At present, wollastonite has a bad influence on the application of wollastonite because of its structural characteristics, and its value is low. It is necessary to modify and coat the surface of the product structure, but the proper coupling agent and needle like wollastonite equipment and process are not well selected. Beset the development of enterprises. In view of the above problems, acicular wollastonite powder will provide advanced technology of wollastonite modification to enterprises, so that wollastonite products can improve their technical performance and economic value.

1. The structure of wollastonite is mainly 1:18-1:25. These structures have special conditions to adjust the modified coupling agent and specific equipment and process flow.

2. The special modified equipment for wollastonite microstructure was selected, and the clouds rotating at the speed of material turnover and vortex suspension could not effectively contact the coupling agent, resulting in low coverage rate. The inner top cover of the modified vessel is designed with a turning and dispersing device, which can disperse and turn down the materials floating in high speed.

3. According to the length diameter ratio of wollastonite structure, special silane coupling agent a172-3 (grafted long-chain oxy propyl hydrocarbon functional group coupling agent) and silane a-172-5 H-chain hydrophilic functional group coupling agent are selected to effectively cover the needle like section of wollastonite, which has strong hydrophobicity.

4. The modified wollastonite structure products are applied to the performance comparison of rubber products and cable products. The technical content of wollastonite products will be increased and the economic added value will be increased.

5. The problem of wollastonite application in rubber products is solved, including the application field of wollastonite.
