Chong Hing perlite Description: Expanded Perlite is a naturally acidic glassy lava non-metallic minerals, including perlite, pitchstone and obsidian, only three different crystalline water content. Because of its volume at 1000 ~ 1300 ℃ rapidly expanding high-temperature condition of 4 to 30 times, it is referred to as expanded perlite. General requirements for expansion in multiples of> 7 to 10 times (obsidian> 3 times available), about 70% silica. Both open pit mining. No dressing, just crushing, screening can. Chong Hing perlite Note chemical composition: about Silica SiO2 68-74% Al2O3 12% alumina, iron oxide Fe2O3 0.5-3.6% calcium oxide, magnesium oxide MgO 0.3% CaO 0.7-1.0% K2O 2-3% potassium oxide Sodium Na2O 4-5% Chong Hing Water H2O 2.3-6.4% perlite main purposes: perlite is extremely versatile of an inorganic mineral material, involving almost all areas. For example: ① oxygen machine, cold storage, transportation of liquid oxygen liquid nitrogen as filling insulation material. ② for wine, oil, pharmaceuticals, food, water filters and other products. ③ used in rubber, paint, coatings, plastics, and other filling materials and vasodilators. ④ for sensitizer. ⑤ used to adsorb the oil slick. ⑥ used in agriculture, horticulture, soil, water and fertilizer, soilless cultivation, soil improvement, pesticides like slow death. ⑦ for profiles with a variety of adhesive tie made of various specifications and performance. ⑧ greater amount of insulation used in industrial furnaces and building on the roof and walls. The construction sector: thermal insulation, fire retardant paint, sound-absorbing panels and other pipeline insulation, cold insulation, filtration materials, set steelmaking process slag material, rubber and plastic filler, etc. Note: application of expanded perlite in addition to the expansion of manufactured goods so some perlite insulation properties, as a basic, adding different binders can be made to adapt to the different needs of the finished product. Can also be used as a filtering agent, catalysts, molecular sieves and carrier rubber, fertilizers, pesticides. Widely used in construction, metallurgy, petroleum, machinery, light industry, hydropower, casting, medicine, food, agriculture, forestry and other horticultural sectors. Often warm thermal conductivity 0.0245 ~ 0.048W / (m · K), high thermal conductivity of 0.058 ~ 0.175W / (m · K), low thermal conductivity of 0.028 ~ 0.038W / (m · K), the maximum use temperature of 800 ℃. Used as a highly efficient insulation, cold filler material. Chong Hing perlite principle: perlite perlite ore is preheated, an internal expansion after transient high-temperature roasting honeycomb structure made of white granular material. The principle is: perlite ore by crushing the ore to form a certain size, the preheated baking, rapid heating (1000 ℃ above), ores vaporization of moisture in the interior softened ore containing glassy swell to form a porous structure, volume expansion 10-30-fold expansion of non-metallic mineral perlite technology and in accordance with its purposes are divided into three different forms: an open hole (open cell), obturator (closed cell), hollow hole (balloon). Chong Hing perlite material advantages: perlite of its good thermal insulation performance, superior performance and stability are well accepted by the market and exert its effects, and a wide range of applications, universal usefulness, especially in fire-resistant thermal insulation plays an excellent performance. Breakdown of performance, it can be said numerous. Not only has a good environmental performance, there is a wide range of applications, economic and social values, the construction is extremely convenient, easy maintenance, impact performance than any other kind of insulation materials, superior anti-heat performance, but also better fire performance. Where durability and buildings with life, completely breaking the organics wall insulation boundaries of the average life of 25 years. Because rock inorganic insulation material systems can be inorganic products, never aging. And seamless construction sector, and thus the formation of the whole building plastic plastic wrap protection. Under normal conditions of use, such as in case of dry, cold, heat, humidity, galvanic corrosion or insects, fungi or algae growth, as well as damage due to sawtooth animals, and various other objects striking the invasion, not cause damage, greatly extend the building life. Insulation materials useful life of buildings with life. The factory provides a variety of uses zeolite powder, bentonite, lithium bentonite, sodium bentonite, perlite gardening, air separation plant with perlite, do washing powder with a pearlescent sand, perlite filter aids, perlite insulation board, construction with glass beads, perlite Cleaner, opening perlite, obturator perlite, expanded perlite and other non-metallic mineral products, according to customer request production of various indicators of perlite products.
