Two-component board glue
5. Usage:
(1) Pretreatment: base material leveling, glue, according to the proportion of the main agent (milky white) and curing agent (dark brown) 10:1 ratio.Stir the glue evenly, and the mixed glue should be used up within 30 ~ 60 minutes.
(2) sizing: sizing should be completed in 1 minute, the cloth glue is uniform and the end cloth glue should be sufficient.
(3) composite: pressure time to be sufficient, the coated plate in 1 minute, 3 minutes must be pressurized, pressure time 45 ~ 120 minutes, special hardwood 2 ~ 4 hours.Pressure strength should be enough, cork 500 ~ 1000kg/m2, hardwood 800 ~ 15000kg/m2.
(4) Post-treatment: after pressure relief to keep healthy, health temperature above 20℃, 24 hours can be lightly processed (saw, planer), 72 hours after the deep processing, during the period to avoid sunlight and rain wet.

Instructions
1、Pretreatment: The moisture content of the wood should be controlled between 8-12%; the bonding base surface should be smooth and flat, without warpage, dust, oil, etc.
2、Sizing: the main agent: curing agent (10: 1) ratio mixing needs to fully stir for 3-5 minutes, until uniform. After the glue is prepared, it should be used up within 1-2 hours. Bubbles and volume expansion may occur during use, which is a normal phenomenon. You can continue to use after slight stirring.
3、Curing: The pressing time is generally 2-4 hours, depending on the temperature
and humidity of the construction environment.
Precautions
1.Base material leveling is key:
Flatness standard: ± 0.1mm Water content standard: 8% -12%;
2. The proportion of glue is very important:
The main agent (white) and curing agent (dark brown) are mixed at a ratio of 100: 10 according to the corresponding ratio;
3. Stir the glue evenly:
Use a stirrer to repeatedly pick up the colloid 3-5 times, without the filamentous brown liquid. The mixed glue solution should be used up within 30-60 minutes;
4. The glue application speed is fast and accurate:
The glue application should be completed within 1 minute. The glue should be uniform and the glue on the end should be sufficient.
5.Pressure time should be sufficient
The coated boards are pressed together within 1 minute, and must be pressurized within 3 minutes. The pressing time is 45-120 minutes, and the hardwood is 2-4 hours;
6, the pressure should be sufficient:
Pressure: softwood 500-1000kg / ㎡ hardwood 800-15000kg / ㎡;
7, after decompression to maintain health:
The health temperature is above 20 ° C, it can be lightly processed (saw, planed) in 24 hours, and can be further processed in 72 hours. Avoid sunlight and rain during the period;
