Plywood adhesive
1. What kind of glue do you have?
Answer: Ge lianghao plywood is divided into synthetic type and compound type. The synthetic adhesive is a high solid content water-based two component imposition adhesive, which is made of vinyl acetate monomer and other modified monomers. The compound jigsaw adhesive is a two-component adhesive made from purchased Franklin EP4 adhesive latex as main raw material, water as dispersant, and additives and fillers as ingredients.
2. What are the characteristics of Ge Liang Hao's plywood adhesive?
Answer: brother two good brand board adhesive is a two component adhesive made from water-based emulsion and isocyanate as curing agent and refined by special process. It has the characteristics of rapid curing at room temperature, high bonding strength, water resistance, weather resistance, heat resistance, strong solvent resistance and tenacity,. The pH value is close to neutral, which does not pollute and degrade wood.
(1) The synthetic type has the characteristics of rapid curing, and is suitable for the use of wood mosaic under medium hard.
(2) The compound type can be divided into two varieties: special hard wood, medium hard wood and soft wood. Its curing speed is slower than that of composite molding, but the dry and wet strength is relatively higher.
3. What is the application range of Ge Liang Hao's plywood adhesive?
Answer: it is suitable for finger joint, tenon joint, splicing, installation and manufacturing of laminated timber, high-grade furniture, high-grade plywood, decorative board, composite floor and other wood products. It can bond hardwood, softwood, hardwood and other wood materials and inorganic materials.
4. How to correctly use GE Liang Hao brand panel glue?
A: when using the panel adhesive, the surface treatment requirements of the glued materials are very high. Otherwise, even the best glue can not achieve good bonding effect. The following requirements should be met:
(1) The surface of the bonded material shall be planed or sanded, and the machining accuracy shall be controlled within ± 0.1 mm to ensure that the surface of the substrate is flat and smooth without knots, cracks, oil stains and dust; the moisture content of the substrate shall be adjusted to less than 12%; the moisture content difference of adjacent substrates shall not exceed 3%.
(2) mixture of main agent and curing agent is 100:15 (weight ratio) and stir 3min ~ 5min to even emulsion. Each batch should be used up within 1 hour (20 ℃) to avoid failure and waste. There will be a small amount of bubbles in the process of use, which will be eliminated by stirring, which does not affect the bonding quality.
(3) It is enough to apply glue once. The amount of glue applied by hand is 260g / m2-320g / m2 (double-sided gluing). 30% - 40% of glue can be saved by machine. The amount of glue applied in summer should be slightly larger than that in winter, and the speed of gluing should be accelerated as much as possible.
(4) The glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued glued.
(5) The applied pressure should be uniform and sufficient, and the pressure should be controlled between 0.7 MPa and 1.5 MPa. Pressure time and pressure need to be adjusted for different materials at different operating temperatures. Generally, the pressurization time should be at least 45min, and the pressurization time will be extended with the decrease of temperature. Avoid vibration or stop during pressure relief.
(6) After pressure relief, the adhesive joint is cured at 20 ℃ for 24h and then machined. The best strength can be achieved after 72h.
5. What should I pay attention to when I make a good collage?
Answer: the following matters should be paid attention to when the two brothers are good at panel gluing:
(1) The bonding ambient temperature shall not be lower than 10 ℃.
(2) Cover the container tightly after use to prevent the glue from scaling. Prevent curing agent from contacting with water and air for a long time to avoid failure.
(3) no iron or copper metal containers should be used, or contact with acid, alkali, banana water or boron compounds to prevent gel failure.
(4) The tools and gluing tools for holding panel glue should be cleaned with water in time after use.
(5) Keep out of the reach of children. Do not enter. The curing agent is isocyanate compound, which is irritant to skin and eyes. If it contacts skin, eyes and mouth accidentally, please rinse it with plenty of water immediately.
(6) This product is a water dispersing adhesive, which is stored and transported as non dangerous goods. Store in a cool, dry place at 10-40 ℃. Due to the difference of individual construction environment and selected materials, it is suggested to conduct field test before construction to ensure the best effect.
