Rubber and plastic insulation material installation technology methods and essentials

Rubber and plastic insulation insulation material installation technology methods and methods Rubber and plastic insulation materials have seven series of products 1 Engineering Class1 rubber and plastic insulation products 2 split air conditioning rubber and plastic pipe 3 composite veneer rubber and plastic insulation products 4 open / closed hole rubber Plastic sound-absorbing board 5 color rubber and plastic products 6 Flooring rubber and plastic materials 7 Supporting auxiliary products The installation of rubber-plastic insulation materials should pay attention to the following points;


All gaps and joints need rubber glue to seal.

After installation, all three links, elbows, valves, flanges, and other accessories must reach the design thickness.

Do not apply too much glue when bonding. The interface between all materials should be bonded under slight pressure.

When the installation should be the first tube after the small tube, the first elbow, straight after the three-way pipe, the last valve, flange.

When installing chilled water pipes and refrigeration equipment, the gaps between the ends of the rubber pipe and the iron pipes must be glued together, and the bonding width should not be equal to the thickness of the rubber material.

The cut slot of the pipeline should be installed in an inconspicuous place as much as possible, and the cutting mouths of the two pipes should be staggered with each other.

Do not install the machine during use. Do not turn on the machine within 36 hours after installation.

The large-diameter rubber-plastic pipe has become oval shape due to the packaging relationship. Plane the flat side when planing.

The correct use of glue:

1 Shake the container before use to make the glue evenly. Pour the big can of glue into the canister and seal it when not in use.

2 Use a short, hard brush.

3 Apply a thin, uniform, special glue to the adhesive surfaces at both ends of the material.

4. The natural drying time for special watering is 3-10 minutes. The length of time depends on the glue grade, atmospheric temperature and humidity. Exposed time is invalid for more than 20 minutes.

5. When used, wait for water to dry naturally. The correct method of measuring dryness is “finger touch method”. Touch the rubberized surface with your finger, if the finger does not stick to the surface of the material, and the surface of the material is not covered by the finger.

6. Just glue the two surfaces of the interface and hold it tight for a while.

7 If the time is too long to be sticky when the two joints are pressed together, repeat steps 2-6.

8 Normally, two square meters of adhesive surface can be applied per kilogram of glue.

9 In general, special glue cannot be used below 5 degrees Celsius. When working in an environment of 5-10 degrees Celsius, the glue is placed in a room with a temperature of 20 degrees Celsius.

10 When there is pressure to understand the two materials, do not have to wait for the glue dry, using wet bonding method, first place the material in the installation, apply glue on the interface of the material, correctly adjust the position of the two materials, and quickly stick Connect firmly.

11 Check whether the anticorrosive paint of the glue and the protective pipe is firmly bonded.

This tape also called pipe anticorrosion adhesive tape, pipe anticorrosion tape, polyethylene cold wrapping tape, 

composite polyethylene anticorrosion adhesive tape, etc. Featuring excellent insulativity, good anticorrosion effect, high mechanical strength, small water absorption, long service lifetime, good resistance to impact and ageing, the product can be used in the construction conveniently with safety and no pollution.
