Rubber insulation material basic technical rules and installation instructions
A: rubber insulation materials installation specification
Rubber insulation material the installation should pay attention to the following:
1, all the cutting gap, joint need colorful card special glue adhesive sealing.
2, after installation of all the three links, elbow, valve, flange and other accessories are required to meet the design thickness.
Don't too hard, 3, glue bonding interface between all the materials should be under mild extruding glue.
4, when installation should first fill after small tube, elbow, tee before they are straight, the last valve, flange.
5, when installing a chilled water and cooling equipment, rubber and plastic will be the gap between the ends of the pipe and pipe coated with glue adhesive, adhesive width should be no is equal to the thickness of rubber and plastic materials.
6, cutting the pipe mouth gap, should be installed in an inconspicuous area and two pipe cutting gap should be staggered.
Do not install
7, the machine is in use. Do not boot loaded after 36 hours.
7, the machine is in use. Do not boot loaded after 36 hours.
8, big diameter rubber tube due to relationship has become oval packing, please split the flat side when they cut it open.
2: to use the glue
1, shake the container before using, make the glue evenly, then the actual installation, with a small can of glue, to prevent the volatile too quickly, if necessary, can be a big pot in a small tank is used, the jar sealed when not in use.
2, use a shorter, hard brush.
3, the material at the ends of the binding surface coated with a thin layer of special glue, uniform.
4, special glue left, natural drying time is 3-10 minutes, the length of time depends on the level of glue, atmospheric temperature and humidity, exposure time over 20 minutes is invalid.
5, when used to glue the natural drying, dry method to correct "touching" finger, finger contact coating surface, if the finger will not stick in material table surface, and the material surface without feeling sticky, adhesive could be undertaken.
6, only when the glue to stick the interface of two surface on hold for a while.
7, if placed too long, so that the two meet together do not have the sticky surface pressure, so please repeat steps 2-6.
8, usually, rubber and plastic special glue can apply two square meters per kilogram adhesive surface.
9, usually, special glue cannot be used under 5 ℃, when in 5 ℃, 10 ℃ under the environment of work, please place the glue on the indoor temperature is 20 ℃, need to use when removed.
10, when the stress is connected under the condition of two materials, don't have to wait for the glue dry, wet glue method is used, the materials placed in the first place, in the material outlet coated with glue, properly adjust the position of the two materials will soon be firm bonding of position according to your design.
11, check the glue and the protection of antirust paint adhesion between solid iron pipe.
Left, drying time: refers to apply glue to the time between material of adhesive.
Rubber foam determine the thickness of heat preservation material factor:
1, the environment temperature is higher, the thicker the material;
2, the relative humidity is bigger, the material is thicker;
3, medium temperature is lower, the thicker the material;
4, the bigger the pipe diameter, the thicker the material.
