1. Before the construction of resin epoxy floor, it is very important for the pretreatment of the original cement ground or terrazzo (terrazzo). The surface must be roughened to make the adhesion between the floor and the resin epoxy paint layer stronger. In the future, heavy objects such as forklifts and carts can be walked on the epoxy resin floor, making it difficult to loosen and peel the floor paint. Multiply the service life of epoxy floor paint.
2. The ideal machine for sanding the ground—The main mechanical equipment for sandblasting the ground is water mill, milling machine, dustless grinder and sandblasting machine (also called shot blasting machine). Among them, sandblasting machines are the best for sanding, and they are often worth more than 100,000 yuan to tens of thousands of yuan. In Taiwan, many customers require the use of sandblasting machines for ground sanding.
The sandblasting machine contains a lot of small pellets. The machine accelerates mechanically, causing the pellets to impact the ground at a very high speed. The ground is roughened and then rebounded and sucked back into the air separator where it is completed. Steel pellets are separated from dust and impurities. Good pellets are recycled into the blasting chamber for dust and impurities transported to the dust collector.
3, after sandblasting the ground, the surface will form a very uniform and fine pockmark, with epoxy floor paint for a very close adhesion. Ordinary grinding machine, or circled, worn out of a circle of arc, or grinding the surface of the ground, the bottom is often not polished.
Which surfaces need to be grit blasted?
4. Because the old paint floor is smooth, it needs to be completely roughened or the whole layer is cleaned and needs to be grit blasted; especially smooth and hard ground, such as corundum hardened ground, the general grinding machine will not wear marks, and it can only idle and need to be sandblasted. Treatment; not to make the damp layer or the surface of the ground with heavy moisture, in order to prevent the pressure of the groundwater epoxy paint will be topped out bubbles, blisters, but also need to increase the adhesion, sandblasting treatment; machine vibration area, to prevent vibration caused The looseness of the floor paint will also need to be grit blasted. Even if it is not the above type of ordinary ground, in order to promote the adhesion of the floor paint and the ground, and then make the floor paint more durable, the best use of sandblasting.
Note: Sandblasting on the ground will increase the cost of the project. Suzhou Ruigu reminds customers to choose according to actual conditions and budgetary costs.
