The method of use is the same as the traditional method of using polyvinyl acetate latex. This product is resistant to freeze-thaw, anti-aging, excellent adhesive strength and long storage period.
1 Wood moisture content should be controlled at 8-15%, too high or too low will affect the bonding quality.
2 The surface of the substrate is treated so that the surface of the substrate is free from oil, dust and other impurities. The adhesive surface must be fully in contact.
3 The glue should be even and appropriate.
4 can be room temperature curing can also be heat curing, the maximum temperature should not exceed 120 ° curing time varies depending on the temperature, according to the actual situation.
5 When pressure is applied, the pressure should be sufficient and the pressure should be uniform. It should be pressurized for more than 1.5 hours. After pressure relief, it should be allowed to stand for a period of time. In order to achieve a better adhesion, it is best to place the product after pressure relief for 24 hours before processing and 72 hours for testing.
6 can be mixed with some resins, such as urea-formaldehyde resin, phenolic resin, trihydrin ammonia resin, etc., in order to improve their own water resistance and creep properties.
1, the bonding operation, the use of the temperature should not be less than 7 degrees Celsius; not high temperature, more than 95 degrees Celsius, will cause the adhesive layer strength.
2, according to different uses, white latex can be diluted with water, but it must first be heated to more than 30 degrees Celsius, and use more than 30 degrees Celsius water slowly added to the mixing can be used, can not be diluted below 10 degrees Celsius cold water.
3, after the start of use, the lid should be tightly sealed, in order to prevent skinning, sprinkle a layer of water, stir evenly when used. And adding a little hydrochloric acid before use can increase the curing speed.
4, can be mixed with other hydrophobic resins into two-component products, improve product bonding strength, water resistance and heat resistance, shorten the curing time.
5. White latex is generally safe but cannot be swallowed or splashed into the eyes. If you accidentally touch the mouth or eyes, rinse immediately with plenty of water.
6. Do not pour white latex into rivers or sewers so as to avoid contamination or sewer obstruction. After use, the residue shall be left standing for storage. After being dried and filmed, solid waste shall be disposed of.
7, storage and transportation: must be stored in a cool, dry, temperature above 5 degrees Celsius, tight tank shelf life of 12 months or more. Storage and transportation should be light and light to prevent inversion, extrusion and exposure.
8. Characteristics of main raw materials such as polyvinyl alcohol, vinyl acetate, acrylic acid and ammonium persulfate in the production process of white latex, and the fire risk in the process of operation. The key points of fire prevention design in the production area are highlighted, including the process flow. Fire prevention, white latex plant fire prevention, tank fire prevention, and automatic firefighting facilities.
