EVA Hot Melt Adhesive for Carton Box Sealing

Product Introduce

Bone Glue is a kind of low purity of gelatin protein, the film is very strong, after the formation of elastic, but not water proof, make the film when exposed to water swelling and loss of bond strength, corrosion resistance is poor, in high temperature, high humidity when might also change.

Product Features:

1. Water less, quickly drying, good shape, high bonding strength, good performance, and the price cheap, easy to use, is the most used in animal bonding materials.
2. Bond Glue is holy bone as raw material, after crushing, oil extraction, scrub much process after processing, such as the regulation of the pressure and temperature of extraction glue protein, product is golden yellow, translucent, microstrip gloss, water absorption, hard an amorphous particles.
3. Use in printing and packaging, textile, papermaking, emery cloth, sandpaper, plywood, match, ink, metal polishing industry production.
4. Should be stored in ventilated dry warehouse.

Main Parameter

Instructions

When using bone glue, soak bone glue with the same volume or a little more water( had better use hot water) for 10 hours or so, make the glue soft, then heat to 75℃ or so, make it into glue solution can be used, The ratio of glue to water should be determined according to the required viscosity, such as water more viscosity is low and thin: add water less viscosity is high and thick. When hot glue temperature should not be too high, temperature is more than 100℃ will be due to molecular degradation and viscosity decline, gum again deterioration. Bone glue is used in the use of a small amount of precipitation, so it is necessary to use the side of the well stirring, in order to regulate viscosity and fluidity, when hot glue must use the bath method, never store glue containers directly heating.

Bone glue should be kept in a certain temperature condition can be used, therefore, when the use of water, water and colloidal temperature should be basically the same, can not add cold water. Because the bone glue should maintain a certain temperature (75℃±10℃), the temperature of the glue will suddenly drop after adding cold water, which will affect the bonding effect. When using bone glue, the adhesive speed should be fast and uniform, do not dip in glue too much to cause uneven adhesive layer, penetration adhesive leakage problems.
