Expanded vermiculite can extensively used in many industries such as construction, metallurgy, chemical industry, light industry, machinery, electric power, petroleum, environment protection communication, transportation and horticulture.Main applications:1.construction materials: light materials such as light concrete materials, light calcimine and light mortar.2. heat resisting material: wall materials, anti-fire board, anti-fire mortar, firebrick, and brake linings.3. heat preservation, thermal insulation and sound absorption materials: underground pipeline, heat preservation material used in hothouse pipeline, decoration material used in  upholstery and tunnel, also wall and ceiling in the public.4.metallurgy: steel frame cladding materials, removal of slag when manufacture of iron and foundry 5. agriculture, forestry and horticulture: golf course lawn, seed preservation agent, soil regulation agent, wetting agent, plant growth agent, feed additives, horticulture mixture, fishing and bait.6 other aspects: adsorptive material, filter aid, active carrier of chemical and chemical fertilizer, sewage treatment, adsorption of seawater oil pollution, cigarettes filter and explosive density regulators.Applications and technology indicators of different sizes:Main specifications and technology indicators of vermiculite:sizebulk specific gravity(Kg/ M2) water absorption(%) thermal conductivity (k·M2·h·ºC) impurity(%) 4-8mm 70-110 480 0.045 3 2-4mm 80-120 465 0.045 3 1-2mm 80-150 420 0.045 3 20-40mesh 100-180 410 0.045-0.055 2 40-60mesh 100-180 400 0.045-0.055 2 60-100mesh 100-180 400 0.045-0.055 2 Production PicturePackage Picture  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
