White latex use, use and detection methods

White latex is the most commonly used type of adhesive in home decoration, its practicality is strong, adaptability is also very strong, so the amount is also very large. White latex is very convenient to use, at room temperature its curing speed is very fast, viscosity is very high, and durability is very strong, aging speed is also relatively slow, can be applied to a variety of materials, such as paste toilet, wallpaper, reinforced cement, bonded wood and so on.
product quality indicators
appearance: milky white, particle-free and foreign
white latex use method
pH value 4 - 6
viscosity (mPa.s, 25 degrees C) more than 250,000
solid content (%) 46 - 50
ash (%) 0. 15
film-forming can be made into colorless transparent continuous skin film
bonding strength (Newton / cm 2) ≥2077 (normal) ≥759 (water resistant)
gel temperature is not higher than (C) 2
use method and effect
white latex, depending on the bonding object, can be appropriately diluted with water
China
. Diluted to add 30 -40 degrees C warm water as a good, not suitable for cold water. When bonding wood, the amount of glue can be applied according to the specific use, generally in two bonding surfaces. After bonding, place for a moment and press for another 3 hours with pressure of 3-5 kg/cm2. At this point the strength can reach about 70-80% of the bonding strength. Full curing takes 8-16 hours. If the method of heating curing is used, the curing time can be shortened, usually at a pressure of 3-5 kg/cm2, about 80 degrees C heating curing. The sheet only needs to be pressed for a few minutes, while the thick plate extends the time appropriately.
Main Use
This product is mainly used for the paste of ordinary wood, paste wood, stickers, also used for pressing splints, synthetic board fiberboard and fire plate paste;
packaging, storage and
series of products using plastic barrel packaging, a net weight of 50KG per barrel. This product should be stored in a cool place, not open-air exposure or freezing, the recommended storage temperature of 10-35 degrees C. The shelf life of this product is six months.
Product Technical Features
1, the use of new formulations, new processes to produce this product, with excellent performance of polymer materials and several other Tesco chemical raw materials formulated, completely changed the traditional white latex materials, formulations and production processes. The production process is simple.
2, the main technical indicators: dry strength, the national standard is 6.9Mpa, this product up to 9.6Mpa, wet strength (after water immersion strength), the national standard of 2.0Mpa, this product up to 4.8Mpa. Viscosity, bonding strength, water resistance, antifreeze performance are far more than national standards.
3, the appearance of the product is milky white, no organic solvents, non-toxic, odorless, non-combustible, non-corrosive, packaging, transportation, storage, easy to use, long shelf life of the product.
4, the performance of this product is stable, good film-forming, film-forming temperature is low, the minimum film-forming temperature is 3 degrees C. With water as the medium, it can be mixed with water, traditional white latex and other lotions when used, and the viscosity and bonding strength of the product can be adjusted as needed. There will be no precipitation, layering, gel, freezing and other undesirable phenomena, no pollution to the production and construction environment.
5, good water resistance, soaked in water for 10 days do not open glue. The film is soft and elastic, with good initial viscosity and high bonding strength.
6, this product on wood, paper, fiber, cement, leather and other materials adhere to the strong, widely used in the printing industry, wood bonding, plywood processing, construction, leather shoes, cigarette industry, paper processing, fiber processing, aluminum foil processing, sandpaper bonding, coatings, decoration and decoration industries. And can be used for paper -plastic, paper-glass bonding, in some areas to replace special glue. Unique water resistance is regarded by paint manufacturers as the ideal low-cost emulsion, the market prospects are very broad.
7, the production cycle of this process is only 4-6 hours, saving time and labor, saving energy, equipment investment is small, high utilization rate. No condenser, reflow unit.
White latex detection method
identification of white latex good or bad method
1, with the finger dot white latex evenly applied to the glass clock tearing to show the hair green almost transparent glue layer can approximate to see the surface object color glue

"four pieces" identified by the white latex paint
"white glue" is short for white latex! Although we may be a little familiar with the name, but a lot of times we will choose white glue when more confused, because do not know how to judge the quality of good or bad.
first is to
shee" can take a small stick in the paint mixing, the quality of white latex paint has layering, precipitation and other phenomena;
the second is the
" can use a stick to pick up the white latex paint, to see if the down-flowing white latex paint can hang out a long wire, is not average;
Thy is "sticky
you can use two fingers to rub, good goods feel very smooth, no rough feeling and grainy feeling, dry and then take water, the quality of better white latex paint is not easy to fall off, demand to key down, poor quality paint is easier to remove;
fourth is to
", the quality of better white latex paint has no breath, the quality of poor paint breath pungent, very stinging. In particular, it is worth mentioning that there are some paint in order to cover up the harmful substances in the paint, in which the addition of spices, shopping to be particularly vigilant about this, the stronger the fragrance of white latex paint more attention to its quality is not a setback.
