Adding wollastonite to engineering plastics is called calcium plastics in the industry because hydrated lime is calcium hydroxide and quicklime is calcium carbonate. In order to improve the strength of plastics, the calcined wollastonite is added.
Generally, add 1% to 5%, and determine the required amount according to the experimental results. Adding too much plastic is easy to pulverize. There are many washing machine manufacturers in order to reduce costs, add 10%, and the washing machine shell will automatically break in about five years.
