2, Bond is that polyacrylamide or concentration are 8% polyvinyl alcohol.
3, emulsion is an organosilicon micro emulsion extracting liquid.
4, antioxidant is 300.
5, infrared reflection coating is a kind ofly can improve solar heat radiation reflection, reduces solar heat and absorbs, and plays the coating of heat insulation and heat control effect.Select infrared nanometer TiO for use
2, hollow ceramic micro mist and some other infrared external reflection fine materials, make infrared reflection coating with specific technology.
Production method of the present invention comprises following program in proper order:
(1) look selects the pitchstone ore, and the ore processing back expansion vitrification identical to color and luster is again to using to prepare thermal-insulating pipe case to the glass bead screening with color and luster.
(2) with 12-15 part brucite, 10-15 part attapulgite, 10-13 part silicon calcium powder, 3-5 part aluminium silicate wool, 45-54 part water is put into the high-pressure metering pump mixing and stirring, is called for short the A material.
(3) in the A material, inject 0.01-0.02 part antioxidant, 0.1-0.15 part Bond and 0.2-0.3 part emulsion, and under 150 degree temperature, stir-lower the temperature.
(4) add 10-15 part expanded and vitrified small ball again, continue to heat stirring-lowering the temperature-will expect that high pressure extrudes the thermal-insulating pipe case-cooling and shaping of all size-the cut out expansion vitrification micro-bead thermal insulation pipe case of all lengths.
(5) in the tunnel kiln about 180 degree after dry 36-48 hour, the normal temperature cooling.
(6) the thermal insulation pipe top layer with moulding evenly sprays infrared emitting paint up to covering and heat insulating pipe top layer, and natural curing is 48 hours under the normal temperature.
(7) test package, finished product.
The main material of expansion vitrification micro-bead thermal insulation pipe case of the present invention is an expanded and vitrified small ball, and expanded and vitrified small ball is formed at 1200 ℃ of-1300 ℃ of hot melts through special processing by pitchstone, water absorption rate own is little, adiabatic, light weight, stable performance, so expansion vitrification micro-bead thermal insulation pipe case has the following advantages: 1) thermal conductivity is little, heat insulating effect is obvious; 2) equipment is simple, easy construction, easy operating; 3) thermal insulation pipe of production all size only need be changed the extrusion die on the extruder; 4) adopt the infrared reflection coating composite thermal insulation, using effect is more obvious especially in the open; 5) the serviceability temperature scope is big, is suitable for the pipe insulation under the different temperatures.Concrete test result such as following table:
