Flame-retardant B1 grade polyurethane exterior wall insulation material is based on isocyanate and polyether as main raw materials. Under the action of various additives such as foaming agent, catalyst and flame retardant, it is mixed by special equipment and foamed by high pressure spraying. A high molecular polymer. Polyurethane rigid foam is a new synthetic material with thermal insulation and waterproof function. Its thermal conductivity is low, only 0.022~0.024W/(m?Κ), which is equivalent to half of extruded board. It is the thermal conductivity of all insulation materials. lowest.
At present, polyurethane foam is mainly used in building exterior wall insulation, roof waterproofing and heat insulation integration, cold storage insulation, pipeline insulation materials, building boards, refrigerated trucks and cold storage materials. Characteristics of polyurethane exterior wall insulation material: unique impermeability; light roof load; good heat insulation, good insulation performance, remarkable energy saving effect; good engineering quality and long service life; convenient construction and fast progress.

The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed of vibration tube, signal detector, concussion driver, structural support, shell, etc.
Mass flow transmitter is a micro-programming-centered electronic system, which supplies
thrust to sensor, transforms sensor signal into mass flow signal & others, and improves
accuracy in accordance with temperature parameter.
It`s composed of switching power supplier, guard grating, core processor board, display
module, etc., installed in a ex-proof junction box. Switching power supply offers power for
transmitter; safe grating isolates sensor and transmitter intrinsically; core processor detects
& processes sensor phase signal, sends mass flow signal and process communication.
