For public natural resources, improve the processing and utilization mechanism is the most reasonable way harmonious use of resources , Vipeak Sand Shandong Heavy demand for perlite expansion under the premise of producing high quality rounded particles can be utilized across multiple industries perlite crushing raw materials.
Since the second half of 2011 , perlite production industry has become a sought-after investment. Perlite raw sand crushing and superfine crushing destroy destroyed, can be used for rubber products, pigments, paints , inks, composed of glass, insulation bakelite and some mechanical components and equipment for filler . The expanded perlite and become a lightweight , multi-functional new information . Light has an apparent density , low thermal conductivity , good chemical invariance , the limitations of the use of a wide temperature , moisture can be small, and non-toxic, odorless , fire, acoustic characteristics, widely used in a variety of industrial parts.
The perlite through after crushing , can be made into insulation materials . Perlite ore include perlite, obsidian and pitchstone . Perlite is the difference between the three arc-shaped cracks formed due to the condensation effect , called perlite structure , the water content of 2 to 6% ; pitchstone gloss with common rosin , 6-10% moisture content ; Obsidian has a glass luster and conchoidal fracture, ordinary water content of less than 2 %. Perlite its characteristics in terms of thermal expansion , the earlier period it was used for insulation and industrial insulation materials . Our perlite ore spread very wide , along the volcanic belt from Hainan , Heilongjiang until , up to 3000 km . According to the relevant part of the calculation , then the use of perlite in the country areas , 65% in construction projects, 30% of the heat pipe insulation , the other for the decorative aspects of the data , and one more for the expanded perlite , we can see , perlite pioneering the...
