" research institute of section monitoring station is built in Shanghai " examining report:
Report number: XB121-100008
The use range of infiltration crystallization type cement base waterproof rubber cement of the present invention:
1) airfield runway, road and bridge harbour, subway tunnel, hydropower reservoir station and ancient building reparation etc.;
2) worker China Democratic National Construction Association Infrastructure, vault, parking lot, grain depot, kitchen and toilet, roofing, balcony, swimming pool tap water engineering;
3) be used to mend a split, the stone material that bonds, ceramic tile, do not ftracture, not emetine, do not get damp;
4) other purposes: can be used as refurbishment system, concrete, the aerating brick, insulation waits the system interface treatment agent.
The method of use and the precaution of infiltration crystallization type cement base waterproof rubber cement of the present invention:
1) processing base level
The basal plane of inspection waterproof layer is handled defective, and is cleaned out.Defectives such as basal plane should be smooth, not dusting, non-scale, free from dust, no discrete particle, no greasy dirt, the obvious crack of no hollowing and hole.
Built-in fitting should be accomplished before waterproof construction, around the tube wall, and inner corner trim, the foot of a wall, the positions of having ftractureed such as cracking place and floor drain need to strengthen special processing, and drainage grade meets the requirements, and the negative and positive angular diameter is not less than the fillet slope angle of 30mm.
Dry like basal plane, the basal plane of must prewetting in advance keeps basal plane fully moistening, but ponding can not be arranged.
Crack treatment: need to cut basal plane and chisel into the V-type groove, and foreign material are cleaned out, tamp with the water-repellent cement rubber cement, shop one deck acid and alkali-resistance grid cloth is strengthened handling.
2) construction process
According to quantity that once stirs and the thickness requirement of once brushing, formation level is brushed.The each material that stirs of control is once accomplished on basal plane, to guarantee the accuracy of coat-thickness.
The coating that stirs is when construction brushing on the plane, generally brushes twice, and coating requires evenly, can not holiday, should notice during brushing that firmly brushing in length and breadth back and forth can coat and reach even to guarantee concavo-convex place.Facade brushing construction should be brushed from bottom to top, and the coating that flows to inner corner trim should in time brush away, and avoids because of piling up the blocked up cracking that causes.
Be used for protection against the tide, moisture-proof barrier, require brushing twice, after the first pass construction, treat preliminary dried solid.Judge the preliminary solid standard of doing, the wall feel is dried, and shake-up can not come off and be as the criterion, and looks the people and walks to destroy waterproof layer and be as the criterion, and carries out the construction of second road again.
Waterproofing layer thickness is generally at 1.2-2mm.When construction brushing is about needing, the left and right sides is crisscross carries out.Should evenly brush during construction, show-through, holiday and packing phenomenon must not be arranged.
At needs enhanced position, as the negative and positive angle, leak, pipeline and Asiatic water closet pan periphery, new and oldly meet place, crack etc., but twice of this product of overbrushing brush 1-2 is as the waterproof enhancement layer.
Retaining test: when coating was done solid 72 hours, retaining 24 hours, ne-leakage point is for qualified, i.e. waterproof system completion.
3) precaution
Use temperature 0-40 ℃, must not construct in rain, snow and strong wind sky, the greasy weather must treat dew receive to do after construction again, construct and rain in back 2 hours or meet rain during construction and should take rainproof measure.
The coating that has stirred used up in 1-2 hour.
Can not add water stirring use again with doing solid coating.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be considered as protection scope of the present invention.
