The composite bactericidal preservative that the present invention uses mainly kills some harmful bacteria, prevents material Corrupt.But result of study display is after step B completes, the coarse fiber sense of material becomes The paste sense of smooth exquisiteness, curing of coating is dried, and the physical and chemical performance having had been provided with basis refers to Mark.Can only speculate accordingly in mechanism: sealed fermenting (or ageing) some probiotics of process or enzyme Being retained, occur biochemical reaction to make chemical bond rupture in fiber modified, natural polymer drops Solving, physical and chemical performance significantly changes, and material is bonded into film properties to be improved.But the suppleness of film forming, Intensity and the main performance index such as waterproof are not ideal enough, so also needing to and water-soluble composite high molecular polymer Emulsion compound use is to reaching preferable intensity and suppleness, and smooth construction surface can be direct Construction.
Construction technology of the present invention is: cleaned up by work surface, brushing, round brush, sprays and is coated with Smear the water dilution of this product, make waterproof emulsifiable paste penetrate into work surface, with substrate strong bonded. After basic unit's dry solidification, it is possible to use any viscosity or the construction of former cream, until forming reasonably thick The dry solidification layer of degree.The construction of each layer, will be carried out after preceding layer dry solidification.Thick Degree does not has strict restriction, but combination property becomes non-linear direct ratio with thickness.Examine for cost performance Consider, it is proposed that dry solidification layer controls 0.6~3mm.If construction surface is rough and uneven in surface, can make should Power is uneven, easily causes the be full of cracks of solidification coating, the water resistance of impact local.For so Work surface, should first significantly hole and crack be repaired before construction, then dilute by appropriateness This product bonding layer of glass net (all can the using of all size size, but aperture released Net performance is more preferably), then at online brushing, round brush, to spray and smear this product the most required Thickness.
Product processes of the present invention do not has liquid and waste slag produced generation, the most in a large number to environment and The gas of human hazard produces.Reaction temperature is in the region of gentleness, so process energy consumption compares Little.Technological reaction pH is positioned at weak acid to weak base region, so the corrosion to equipment is the least, right Operator are also without threatening.Without control class material in reaction raw materials, also without inflammable and explosive class chemistry Dangerous materials, safety in production is ensured.
