Building template brightening additive type has five functions: moisturizing, softening, preventing pitting, improving paper toughness, and increasing brightness. Traditional laminated paper has part of its rubber surface before hot pressing on the machine. Premature curing will reduce the fluidity of the glue during high-temperature hot pressing, resulting in poor thermal curing performance of the membrane paper, and undesirable defects such as twists, spots, roughness, poor gloss, and reduced waterproof performance on the surface. After the additive building membrane paper modification additive is directly added to the (double-impregnated phenolic glue), it can also be directly added to the urea glue for hot pressing. It can effectively improve a series of shortcomings of traditional coated paper, such as being fragile, easy to break, easy to stick, easy to bubble, short in storage period, and low in surface brightness after hot pressing. It is currently the best improved functional additive to improve the quality of building formwork. 1. Product technical parameters: Appearance: concentrated transparent liquid, strong stability and stability coefficient, ionic and non-ionic, viscosity (℃
)
~ Solubility: easily soluble in water, no special odor, specific gravity and melting point: ℃
,
The effective active substance content value is applicable to the building template brightening additive, which can be used to improve the quality and performance of various colors of membrane paper and templates. The three-product purpose building template brightening additive can effectively extend the storage period of the laminated paper to facilitate long-distance transportation and long-term storage of inventory by manufacturers. It can effectively improve the flexibility of the laminated paper to reduce the cost of transportation and handling. The damage rate caused can effectively improve the fluidity of the adhesive film layer to reduce twists, spots, and roughness caused during the thermal curing process. It can effectively improve the gloss and smoothness of the adhesive layer after lamination, thereby improving the surface quality of the building formwork. and increase the number of repeated uses. Four usage methods: After the production of phenolic glue or urea glue, it can be added directly to the reaction kettle for uniform mixing. It can also be added to the batching tank for mixing evenly when the second dipping ingredients are mixed. The addition The amount is the total amount of phenolic glue (weight percentage), it can also be added directly to the urea glue and stirred evenly. The amount added is the total amount (weight percentage) of the urine-formaldehyde glue (can be adjusted according to the viscosity of the urine-formaldehyde glue). If you are producing black film paper, it is recommended to add it together with sulfide black and stir evenly. 5. Precautions: Before operation, be sure to make sure that the brightening additive for the building formwork and the glue are stirred evenly (generally just add it to the surface glue. Because the brightening additive for the building formwork is concentrated, if it comes into contact with your eyes, wash it off with plenty of tap water immediately. Keep away from children when operating, please store in a dry and cool place, valid for three years
