ZRD Rockwool Sound Insulation

          ZRD industrial Rock Wool Blanket is flexible and can well fit irregular equipment and large pipes. Its good length can effectively reduce the number of joints and thermal bridges. Water repellent type and low chlorine type of products can be manufactured according to the requirement of customers.ZRD ROCK WOOL BLANKET We have many product advantages, such as better thermal conductivity and softer fiber diameter, which can ensure that during on-site construction, after opening the rock wool roll felt, the normal thickness range can be maintained, and the fiber diameter of the rock wool roll felt does not break, which can provide customers with good insulation and fire prevention effects and achieve efficient utilization of rock wool products.

 

ZRD-Industrial Rock Wool-China rock wool factory with CE certificate.

ZRD industrial insulation rock wool is widely used in nuclear power plants, power plants, chemical plants, refineries, pulp mills, steel mills and other industry fields, such as various process pipelines, industrial equipment, boilers, and storage tanks. It cuts down on heat loss in production, increases production efficiency, ensures process stability, provides safety protection, and reduces noise.

The features of ZRD ROCKWOOL INSULATION industrial insulation rock wool include: high temperature resistance, excellent water repellency, high corrosion resistance, and low thermal conductivity. It can provide the highest level of protection for boilers, furnaces, distillation towers, valves and pipelines in petrochemical, power plants and other industrial production from heat and energy loss, fire, noise and other harmful effects.

ZRD industrial insulation rock wool meets both domestic and international standards, such as GB11835, GB50264, DL/T5072, SH3010, ASTM C612 and JIS A9504; thereby, it satisfies all the requirements in performance tests.

Product introduction of the stone wool blanket

ZRD Stone wool blanket is made from natural rocks such as basalt and limestone. The rocks are melted in a cupola at temperature of >1450 , and the molten lava is fiberized by a spinner. The inorganic fibers are bonded together using a thermosetting resin to form the final product which is cut into suitable sizes for easy handling and installation. STONE WOOL blanket is widely used in public, commercial and residential buildings as well as industrial plants, for applications such as roofing, external wall, partition wall and floating floor to provide fire protection, thermal insulation, acoustic control and condensation control.
