SINOYQX Thermal, Sound, & Cold Insulation for Trains, made from SINOYQX melamine foam I series, is a light-weight, excellent sound absorption and thermal insulation performance and fire-resistance foam. It is ideal materials for trains sound, thermal & could insulations.

SINOYQX Melamine foam thermal, sound and cold insulation for trains

Installation of Thermal, Sound & Cold Insulation for Trains

After the installation of cold resistant and sound absorbing material, when the locomotive is under low temperature condition, the cold resistant material shall perfectly insulate heat or preserve heat for the cab. If the locomotive operates when there is loud noise outside the cab, the cold resistant material shall perfectly insulate sound for cab to reduce noise inside the cab. The cold resistant material shall have appropriate rebound rate so that it can gradually rebound when it is extruded during installation.

The cold resistant and sound absorbing material is mainly used in the frame of cab and between the frame and the skin to be cold resistant, preserving heat and absorbing sound. Installation dimensions, According to the drawing for the steel structure of cab. Weight and center of gravity Weight of cold resistant and sound absorbing material of various specifications shall be determined according to the dimension and density of the drawing. Material Except cold resistant and sound absorbing material on the floor of cab, the cellular plastics are seal packed by aluminum foil.

Fire prevention of Thermal, Sound, & Cold Insulation for Trains  

When the material is not in contact with open fire, it is flame retardant; when the material is in contact with open fire, its surface will start to burn and it will be automatically extinguished after the open fire leaves. If the fire retardant is not added, the fire protection can reach the flammability class S4, anti-dripping class ST2 and smog spreading class SR2 of DIN 5510-2 Preventive fire precaution in railway vehicles.

Design for environment compatibility of Thermal, Sound, & Cold Insulation for Trains  

YarQuenXer Melamine foam shall be such designed to generate a minimum environmental pollution during its manufacture and use. The design considerations shall include compliance with requirements of environmental protection law in the product operation, maintenance and servicing, as well as disposal (recycling, waste disposal). The materials and their compositions and chemical compounds shall be selected in accordance with following requirements:

a) The rate of harmful substance should be as low as possible;

b) The service life of product / material should be long;

c) There should be reusable or recoverable materials;

d) The types of materials should be as few as possible.
