How to reduce the cost of urea-formaldehyde resin

I. Introduction: We. Introduction:

The availabilitymonetary crisis problems has seriously impacted China 's wooden- based panel industry, and it has additionally brought unparalleled affect manufacturing in urea- formaldehyde resin stuff. Where is just how away? The only path out-- only keep costs down! It will always be of huge significance to help make new urea- formaldehyde botanical adhesives to lessen cost chemicals.

Second, the functions:

The clean urea- formaldehyde resin cement adhesive reduces the fee additive, which will is obtained by heating response of corn starch and plastic depot. The additive is not really just delaminated, non- precipitating or any- gel is the most common colloidal property, and it could be along with urea- chemical resin glue in just about any percentage. It generally does not impact the life and basic properties in urea- formaldehyde resin stuff. Generally, the proportion of urea- formaldehyde resin glue is normally 10- 30%. Features: just cost reduction, no quality decrease, almost no influence on urea-- formaldehyde resin glue.



Final, the availability process:

1. Put 1000 kg of water to the response kettle, add eighty kg of corn starch through adding 2 kg of stuff to the treasure.

2. Mix for 1 hr, heat to 95° C, and continue maintaining warm for 5- 12- a quarter-hour.( Note: the temperature need to not get too quickly)

several, wanting to cool-down to below 50° C, the truth that is, urea- formaldehyde botanical glue to lessen cost chemicals.

Because iwg urea formaldehyde resin powder is a large- tech product created by a good special process, the method in use is very simple , and the production process will not even require to change the acid and alkali, and does not require to observe the pH worth.

Fourth, cost analysis:

Seeing this type of , you have to say that a number of these the best deal must become expensive? The solution is : plenty of price of 300 yuan.

Hammer toe starch 2000 yuan/ lot, 80 kg× 2. zero yuan= 160 yuan.

Jiao Debao 65 yuan/ kilogram, 2 kg× 65 yuan= 130 yuan

The natural material price of 160+ 130=290 yuan could be produced, 1000 kilogram water+ 82 kg= 1. 08 plenty of urea-- formaldehyde resin glue to diminish cost additives, 290÷ you. 08= 270 yuan/ ton.

Fifth, the application form:

The newest additive even offers the home of reverse compensation, which is usually unavailable in other price- reducing additives. The preservative reacts with formaldehyde to type a hardcore, hard, high-- strength polymer material, thereby minimizing the urea formaldehyde when added. The result of resin stuff. Its reaction with formaldehyde indicates that it also has a great aldehyde- reducing function.

Identical to theadditive made by 641 Uf Resin Powder is normally also obviously not identical to the starch glue of general meaning. Earlygelatin will react with all the starch comprehensive, such as the grafting in the first level as well as the coupling in the later stage, last but not least become a typical colloid. It can truly be applied in high- midsection and low- grade urea- formaldehyde resin glues. This is added in just a good large number and can be blended with urea- chemical resin glue in just about any percentage. Moreover, it could become used not merely on urea- formaldehyde resin but likewise on resin glues including phenolic resin and melamine. This can be the initial property that is not actually easily achieved by other chemicals.
