Methods To Improve The Quality Of Artificial Quartz Stone Slabs

After rapid development in recent years, the production of artificial quartz slabs, such as the classic quartz slabs in my country has increased sharply. According to statistics, the annual output of quartz stone is over 10 million square meters, of which a considerable part is exported abroad.

 

As the application demand for artificial quartz slab in my country continues to increase, the quartz stone market is entering a rapid development track, enabling some large-scale quartz stone manufacturers to develop rapidly.

 

But it is precisely because of this reason that my country's quartz stone market is chaotic, and there is a huge gap in the quality of artificial quartz  slab. For how to improve the quality of artificial quartz slabs, we can consider from the following aspects:

1. Reducing the amount of resin used in artificial quartz stone slabs

Reducing the amount of artificial quartz stone resin is the need to reduce the cost. Every 1% reduction in the resin amount will save 7 yuan per square meter of the slab (take a thickness of 2cm as an example).

Also, for the technical requirements of export slabs, the export requires that the quartz content of the slabs is 93%. That is, the resin content must be controlled within 7%.

The factors affecting the amount of quartz stone slab resin are determined by the parameters of the quartz stone slab press as stated below;

(1) The pressure applied by the press head will affect the amount of sheet resin.

After many tests and on-site statistics, it is found that when the pressure applied to the press head is less than or equal to 1kg/cm2. If the amount of resin used is 8%-9%, it will not meet the export requirements.

 

When the pressure applied by the pressure head of the press is ≥5~10kg/cm2, the resin used is 6%~7%. If you want to make the product meet the export requirements, you can use cylinders and oil cylinders to add force.

(2) The vibration frequency of the vibrator on the indenter also affects the resin used in the artificial quartz slab.

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

 

2. Improving the production technology of quartz stone slabs.

(1) When observing the surface finish of the board, it is found that the areas with particles are bright, but the powder is not bright.

 

The powdery part is not bright, which is caused by the low hardness of the quartz powder. Therefore, increasing the hardness of quartz powder is an effective way to improve the hardness and smoothness of the slab.

(2) The watermark problem of fine-grained quartz slabs is a difficult problem to be solved in the production of quartz slabs.

 

The so-called watermark problem, in addition to the formula problem, is actually caused by the different densities of the entire surface of the board. That is, the pressure and vibration force on the whole board during pressing are different. The solution is to increase the rigidity of the indenter.

 

(3) Increase the variety of patterns on the surface of the quartz stone slab and expand the scope of use of the quartz stone slab.

 

At present, the surface of the quartz stone slabs produced in our country is all flat. With the development of decoration, the surface is required to be made into a natural surface, which requires the application of new technology.

 

This requires the participation of our company's core technology and production personnel to work out an optimal production process. I believe that shortly, our company can use this technology to provide customers with higher quality quartz stone.
