The kraft paper embossed stucco aluminum sheet coil is made from kraft paper as a processing cloth, and the kraft paper is firmly bonded to the stucco embossed aluminum thru the high temperature and excessive strain. The normally used substances are 1060, 1050, 3003 and 5052 aluminum sheet plate, and the tempers are H14, H24, H16, H18, etc., the thickness range zero.1-3.0mm, the thickness of kraft paper is 10-15 micro. Due to the kraft paper has suitable ductility, sturdy moisture-proof characteristic, the stucco embossed aluminum with kraft paper are desired with the aid of customers because of the best corrosion resistance and outstanding value maintenance in thermal insulation enterprise.
There are strategies for coating kraft paper on the floor of stucco embossed aluminum:1: Bonded by using glue, the surface of the kraft paper is glued by using itself, the gain of this technique is high manufacturing performance, activate transport, low production cost, the daily output can attain 30 tons. The shortcoming is that due to temperature modifications, the surface of the kraft paper is liable to bubbles, which affects the bonding impact, and the garage time in the outdoors should no longer be too long.
2: the kraft paper and the stucco aluminum sheet are bonded together by using heating. The gain of this product is that the adhesion is very excessive, the water immersion test does no longer open the glue for twenty-four hours, and does no longer fall off. The climate resistance is extraordinarily excessive, and the kraft paper isn't always stricken by temperature changes, and the downside is that the manufacturing performance is gradual and the production price is too high.
