Fire isolation belt refers to the isolation space and related facilities that protect life and property functions in order to prevent large-scale fire from burning. The fire isolation belt is installed in the external thermal insulation system of the flammable insulation material. In the horizontal direction, the non-combustion insulation joint is used to prevent the fire from spreading along the external wall or in the external insulation system of the external wall.
Rock wool board fire barrier and phenolic fire barrier are two types of fire barriers widely used in the construction industry. So, what are the similarities and differences between the two?
First, rock wool slate wool fire isolation zone
The rock wool board fire isolation belt should be supplied with the external wall insulation system. The outer wall insulation system of the rock wool board fire barrier shall be reliably connected with the base wall, and shall be able to adapt to the normal deformation of the base layer without cracks or hollow drums. It should be able to withstand long-term repeated effects of self-weight, wind load and outdoor climate. It should have waterproof penetration properties without causing harmful deformation and damage. With a certain thermal insulation performance, the thermal resistance of the fire barrier should not be less than 40% of the thermal resistance of the external thermal insulation system.
Second, the phenolic board fire barrier
The phenolic fireproof insulation belt construction method refers to the specific method of fixing the fireproof insulation belt to the outside of the outer wall, including the location of the fire isolation belt, the size of the insulation material, the type of insulation material, the bonding method and the area. , the number and distribution of anchor bolts, the type and thickness of the protective layer material, the type of facing material, etc. There are mainly the construction method of the fire insulation barrier of the paste insulation board and the construction method of the fire insulation isolation zone of the insulation decoration board.
Our Fiber Optic Splice Trays are made of ABS, light in weight and is RoHS compliant. It mainly is used for optical fiber storage and fiber optic fusion protection, easy to operate and simple to install and uninstall. The Fiber Splice Trays are stackable and can be mounted using two #6 screws; they can be used one on top of another to form a layer structure inside the fiber optic enclosures.
Usually fiber optic splice trays are used inside the Fiber Enclosures, optical fiber glass inside the fiber tray can be melt with any other strand optical fiber in the tray, thus different fiber optic cables can be melt connected directly via the tray, optical cable fiber can also be melted with the fiber optic pigtail end, and via pigtail it can connect out to other fiber optic equipment. The tray expands fiber splice capabilities as well as provides the splicing location for the fiber optic cables. we have ready stock of this series products for immediate shipment.
