The method of improving the quality of artificial quartz stone plate in stone decoration engineering

After the rapid development in recent years, China's artificial quartz stone plate production has increased sharply, the annual output of nearly 10 million square meters, a considerable part of which are exported abroad. quartz slab The current problem is how to improve the quality of artificial quartz stone plate, I think it can be considered from the following aspects.

First of all, reduce the amount of resin used in artificial quartz stone plates

The cost must be reduced to reduce the amount of synthetic quartz resin. For every 1% reduction in the amount of resin, 7 yuan will be saved per square meter of sheet (such as 2cm thickness).

is the need of export plate information technology development requirements, engineered stone benchtops export enterprises require the quartz content of the plate 93%, that is, the resin content we must strictly control within 7%.

According to the process parameters of the quartz sheet press, the factors affecting the resin content of the quartz sheet were determined.

(1) The pressure applied by the indenter will affect the amount of sheet resin. After many tests and on-site statistics found that when the pressure of the head is less than 1kgu002Fcm2, if the resin dosage is 8%? 9% fell short of export requirements. engineered stone supplier When the pressure applied by the head is ≥5? 10kg/ cm2, the resin used is 6%? 7%, in order to make the product meet the export requirements, cylinders and cylinders can be used to apply force.

(2) The vibration frequency of the indenter vibrator also has an impact on the resin content of the quartz stone plate.

(3) The vibration of the vibrator must match the pressure applied by the indenter.

At present, the parameter information of the press used by many artificial quartz stone plate production plants in our enterprises is different frequency 2900, and the unit working pressure is less than 1kg/cm2, so the technical content of the coarse quartz stone slab resin we produce is 8%. About 9%, fine particle quartz plate resin content 10%? About 11%. The above figures can show that with the production of quartz stone sheet resin in China, the main task is very heavy, and the potential is great, how to do? Modify the press so that it can reach its required parameters.

The second is to improve the quality of quartz stone plate

1. When observing the surface finish of the plate, it is found that the place with particles is brighter, but the powder is not bright. The powder is not bright, caused by the low hardness of quartz powder. Therefore, increasing the hardness of quartz powder is an effective way to improve the hardness and smoothness of sheet metal. After many tests and applications, it is found that adding 10% of 100 mesh flat glass powder to 325 mesh quartz powder can increase the Mohs hardness of the plate by 0.5 and improve the surface finish.

2. The watermarking problem of fine quartz plate is a difficult problem to solve in the production of quartz plate. Generally, manufacturers are starting from improving the mixing effect of the mixer, and solving it before the cloth surface increases will receive a certain effect, but it cannot be eradicated. After careful study, the so-called watermarking problem, in addition to the formula of a problem, is actually due to the different density of the entire plate, that is, the pressure and vibration force of the entire plate at different points in the compression process, and the solution is to improve the head stiffness.

3. Increase the color types of quartz stone plate surface and expand the application range of quartz stone plate. At present, the surface of the domestic production of quartz stone plate is flat. With the development of decoration, it is required to make the surface natural, which requires the application of a new technology.
