1. Product profile
Have solvent surround oxygen coating mainly in order to modify epoxy resin as mainly becoming the membrane thing, utilize active dilution to increase tough pharmaceutical to realize having no solvent. Entrust to coating good glueing the relay, excellent chemical stability and mechanical performance.
2. Function characteristic
A.The joining of the flaky packing of scale not only can improve the mechanical performance of the coating, but also can play a going to the good coating to shield role, have good antiseptic function.
B.There are no solvents the complete network of surrounding coating of oxygen solidify the pharmaceutical viscosity low, the coating has good antiseptic performance after solidifying, hardness toughness and density. Have relatively more suitable service time and solidify time.
C.This coating has been also improved a lot in glueing the relay, toughness, assaults the intensity, are able to bear the intensity of stripping besides having fine and insulating, excellent chemical stability. There is no solvent to volatilize while constructing, become membrane degree and can reach above 200 ¦� m once, there is no needle hole disadvantage. Save the energy, protect the environment.
3. Apply range
Have solvent surround oxygen coating have intensity to be heavy, solid content high, anticorrosion of good performance, construction process simple having numerous advantages such as environmental pollution. Apply to urban pipeline antiseptic, bury pipeline antiseptic mending mouthing, elbowing, in charge of body person who bury antiseptic serious antiseptic field of overhauling etc. of the pipeline extensively at present.

5. Coating construction
A£®The surface is dealt with: " paint steel products surface corrosion grade load with, and eliminate rust grade " regulation carry on surface punish and reach Sa2.5 grade " according to GB8923, remove the steel tube surface dust.
B£®The formulating of coating: It is a piece of coating of one pair of groups that TL - 3 has no solvent to surround high-strength coating of oxygen, one was formulated by group A, B, should stir the share per group evenly while using, then in proportion(A: B =100 : 20 - 25 Allocate the proportion and can be adjusted on the basis of ambient temperature of concrete construction). Mix and worthy of stiring, finish applying paint with a brush within stipulated time. Can brush construct, can paint, can make, blow, paint with roller, pairs of component have angry spraying plane go on, construct. The steel tube surface anchor line profundity after eliminating rust should be between 50-70 ¦� m.
6. Coating test
Should carry on the appearance, thickness, leak one to antiseptic floor and glue the relay to experience. The appearance should be taken the form of and levelled smooth painting the membrane form. The thickness adopts and can't harm and examines thick appearance measurement. Electric leakage inspection adopt electric spark needle hole examine appearance with to stop leakage in the roof voltage go on, check 2000V. As to thickness, leak electricity, check, should mend, scribble while being not up to standard. Glue the relay to examine and go on according to the standard regulation of bitumen coating of oxygen coal of the ring.
