Description

BC-0802 is a composite sand addition, mainly a certain proportion of bentonite mixed with pulverized coal, in addition to some other materials as needed, such as ¦Á starch, alkali lignite, natural asphalt and cellulose.

Main Advantages

• Solve the problem of spontaneous combustion of pulverized coal

• Improve the accuracy of adding the sand mixer, and reduce the sand fluctuation

• The flame retardant effect of bentonite makes the higher moisture of the mixed clay compared with the coal powder, which is better to reduce dust.

• The mixture ratio and additives can be freely customized, which is conducive to stable sand performance, improve casting quality, and ultimately reduce the comprehensive cost

Instruction for Use

1. When preparing BC-0802, it should be mixed in accordance with a certain proportion and ensure that various raw materials are fully mixed. 2. When BC-0802 is used, mold design should be carried out according to the specific situation, and parameters such as pouring temperature and time should be controlled. 3. When storing BC-0802, it should be avoided from moisture or excessive drying to ensure its stable quality. In actual production, the formulation may need to be adjusted to meet the requirements of different castings. The following are some common adjustment methods: Increasing the gypsum content can improve the hardness and strength of the mixture, which is suitable for castings that require higher strength.

Packaging
