    New starch filler is our latest developed new products in the plywood and paper mills, mill cartons, gift boxes and other industrial manufacturing plant in the role instead of starch, effective, low price, is a non-multi-get the new material.Our customers lower production costs in line with the purpose to welcome useful in the production of starch with manufacturers and we strive to reduce production costs.

   Flame-retardant filler is a new type of starch, non-toxic, tasteless, not afraid of fire, not bad functional green moldy materials, it is the use of several organic materials specially processed composite production technology is a unique molecularstructure and chemical properties of new materials with large surface area, more than the gap, mobility, dispersion, absorption of moisture and good and good viscosity, low hardness, it is added to the starch as filler instead of plywood or in paper mills, carton mill and other industries need to use starch instead of starch, with good adhesion, suspension, dispersion, mobility, adsorption and thixotropy.

New starch filler in plywood role

A: the basic characteristics of novel starch fillers

1: In the urea-formaldehyde resin easily dispersed, and urea-formaldehyde resin can be a good solubility, good suspension, no layered precipitation, flow, and can ensure the uniformity of sizing and filler in the distribution layerequilibrium, while with the board to increase the resin surface of the substrate contact area, which serve to prevent the resin cured in the hot contraction caused due to produce plywood warping, distortion, bubbling, transparent plastic and other defects, enhanced resinthe glue, and improve the quality of plywood.

2: a thixotropic, to follow through the appropriate mix to adjust production requirements and to ensure consistency without colloidal precipitate.

3: with adsorption, on the one hand to a certain extent, reduce the formaldehyde emission of plywood when hot, reduce odor, improve the shop floor environment, compared with starch as filler to reduce the free formaldehyde content better.

4: adding urea-formaldehyde resin glue does not increase the activity of the base, glue itself does not affect the water resistance, while penetration into the pores of the veneer, the veneer moisture adaptability, can reduce the plywoodbubble gum and beat the phenomenon of open and improve the plywood's senior product rate.

5: the role of water to prevent excessive penetration of glue to glue veneer to cause lack of affect bonding quality.

6: to improve urea-formaldehyde resin adhesive bonding strength of the knot is better than a good starch as filler.First, the initial viscosity is better able to adapt to the cold process; Second, there is moisture absorption, easy to do, save the viscosity of a relatively long time, is conducive to hot pressing process.

7: Adding a new starch filler to suppress the plywood, the dry and wet bonding strength difference between the minimum bonding strength of urea-formaldehyde resin binder to improve water resistance of starch filler is better than good.

8: Compared with the starch filler, a new starch fillers can better penetrate into the wood tissue space, the co-existence is the urea-formaldehyde resin layer between the molecular structure, the layer more flexible, to avoid the glue arising from the lack of plasticphenomenon, especially in the case of low viscosity glue, the high moisture content of wood and porous species, the effect is more obvious.

9: After curing adhesive glue is not easy to aging, low hardness, wear and tear on the blade small.

10: chemical stability, added urea-formaldehyde resin and long-term storage is not bad.

11: high solid content than starch filler, filler lower prices than starch.

II: A novel starch fillers and requirements to use

1: The new good initial viscosity of starch filler in the production of plywood can be used alone instead of starch, and starch can be mixed.

2: the use of novel starch filler resin glue should be based on the concentration (solid content) determined the concentration of glue big use less glue can add a small concentration of more general use of liquid urea-formaldehyde resinweight of 15-25%.

3: Use a new starch fillers should be added while stirring filler, stirring 3-5 minutes, so filler mixed with glue before use.If and when mixed with starch, glue should be added in the new starch filler, and then adding a small amount of starch to glue consistency to process requirements, you can use.

4: The deployment of a good resin glue consistency after mixing in the stop will be gradually increased, should be stirred once every half hour, preferably while stirring while using, avoid excessive impact on the consistency of glue coating quality.

5: Use a new starch filler, the board substrate surface temperature is not too high (ie, veneer from drying out the pit after pit landscapes certain time, to avoid a pit board immediately after the coating), the substrate boardThe moisture content of 12% is most appropriate.

6: Using the new technology of starch filler when hot conditions require: working pressure of not less than 1.372mpa, the temperature in the range of 105-115 ℃; pressing time (calculated by thickness), not less than 55 seconds / mm thickness,that should be higher than the original use of starch as filler, be extended 60-80 seconds.

7: The original glue added in the resin curing agent, the use of novel starch filler, the glue should be based on appropriate adjustments to changes in the PH value of the added amount of curing agent.

Three: the new starch filler storage requirements

     A novel starch fillers requirements stored in ventilated and dry place, try to avoid a hard object storage place, so as not to scratch the packing layer resulting product leakage; avoid the sun, water washout, and moisture, at room temperature.
