What is the thermal conductivity of vermiculite and vermiculite?
Vermiculite has higher layer charge number, so it has higher cation exchange capacity and stronger cation exchange adsorption capacity. Characteristics: light weight, and good adsorption properties, not decay, can be used for 3-5 years (unlike the humus, coconut shell, clothing and other perishable)
Vermiculite is a kind of hydrate, which is blocky, flaky and granular. It is the product of weathering and alteration of natural mineral such as biotite. The interlayer water molecule is ignited at high temperature, and the volume is increased by 18-25 times. Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other ingredients.
Cement and expanded vermiculite, cement should be no less than 325, usually choose 425 ordinary Portland cement. The volume ratio of cement and expanded vermiculite is generally 1:5, which is economical and reasonable. Cement and sand aspect than the general 1:1. Site inspection method: mix the cement paste with fine powder and knead it by hand.
