膨胀珍珠岩

玻化微珠

    一种天然酸性玻璃质火山熔岩非金属矿产,包括珍珠岩、松脂岩和黑曜岩,三者只是结晶水含量不同。由于在1000~1300℃高温条件下其体积迅速膨胀4~30倍,故统称为膨胀珍珠岩。一般要求膨胀倍数>7~10倍(黑曜岩>3倍,可用),二氧化硅70%左右。均为露天开采。不用选矿,只需破碎,筛分即可。可用作过滤剂、催化剂、分子筛以及橡胶、化肥、农药的载体。广泛用于建筑、冶金、石油、机械、轻工、水电、铸造、医药、食品、农林园艺等部门。经常温导热系数0.0245~0.048W/(m·K),高温导热系数0.058~0.175W/(m·K),低温导热系数0.028~0.038W/(m·K),最高使用温度800℃。用作高效保温、保冷填充材料。

A kind of natural acidity glass lava nonmetallic minerals, including perlite, rosin rock and obsidian, only three different crystallization water content.In 1000 ~ 1300 ℃ high temperature under the condition of its rapid expansion volume 4 ~ 30 times, therefore, collectively known as expanded perlite.General requirements expansion ratio > 7 ~ 10 times (black obsidian > 3 times, available), silicon dioxide by about 70%.Are all open.Without separation, crushing, screening.Can be used as a filtering agent, catalyst, molecular sieve, and rubber, the carrier of fertilizers and pesticides.Widely used in construction, metallurgy, petroleum, machinery, light industry, water and electricity, casting, medicine, food, agriculture, forestry and gardening departments and so on.Often temperature coefficient of thermal conductivity of 0.0245 ~ 0.048 W/(m K), high temperature heat conduction coefficient is 0.058 ~ 0.175 W/(m K), low heat conduction coefficient is 0.028 ~ 0.038 W/(m K), the highest temperature 800 ℃.Used as a efficient insulation, cold insulation filling material.

 膨胀珍珠岩是由酸性火山玻璃质熔岩 (珍珠岩)经破碎,筛分至一定粒度,再经预热,在14000C以上高温延时烧结而制成的一种白色或浅色的优质绝热保温材料。其颗粒内部是蜂窝状结构、无毒、无味、不腐、不燃、耐酸、耐碱。可以用不同的粘合剂制成不同性能的制品,其特点是 容 重轻、绝热及吸音性能好, 具有吸附能力。 产品应用:  膨胀珍珠岩是应用极为广泛的一种材料,几乎涉及到各个领域,
例如: 1) 制氧机 冷库、液氧液氮运输的填充式保温隔热。 2) 用于橡胶、油漆、涂料、塑料、等填充料及扩

Expanded perlite is by acidic volcanic glass lava (perlite) through crushing, sieving to a certain size, then through preheating, in high temperature above 14000 c delay sintering and made a kind of white or light color quality insulation material.The particle is internal cellular structure, non-toxic, tasteless, does not rot, non-combustible, acid-proof, alkali resistance.Can be made different performance of different adhesives products, its characteristic is to let light weight, thermal insulation and sound-absorbing performance is good, has the adsorption ability.Product application: expanded perlite is a widely used material, almost involve all fields,
For example: 1) the oxygen generator, liquid oxygen, liquid nitrogen transport of filling type refrigerator heat preservation and heat insulation.2) used in rubber, paint, coatings, plastics, such as filling material and enlargement

 3) 用于敏化剂。 4) 用于吸附浮油。 5) 用于农业、园艺、改良土壤、保水保肥。 6) 用于与各种粘合剂配合制成各种规格与性能的型材。 7) 更大量的用于工业窑炉与建筑物屋面与墙体的保温隔热上。 

3) with Yu Minhua agent.4) used for adsorption of oil slick.5) used in agriculture, horticulture, soil improvement, retention of fertilizer.6) is used to cooperate with all kinds of adhesive made from a variety of specifications and performance profile.7) greater amounts of industrial kilns and building roof and wall of heat preservation and heat insulation.
