Several reasons lead to quartz deformation
There are several reasons which will cause deformation:
1. The formula of quartz stone
The composition of quartz stone contains the curing agent, and the quality of the curing agent is essential:
1.1 The manufacturer should not easily change the supplier of the curing agent or the type of the curing agent;
The quality of the curing agent from different suppliers is different, and the formula of the curing agent is different from the different models.
1.2 Curing agent percentage and reaction temperature; time is also essential.
The percentage of the curing agent should adjust according to the different temperatures in summer and winter, and according to the different colors, the proportion of resin should adapt.
The curing temperature must be at least 80 ° before the curing agent can begin to function.
The curing time, on the one hand, is also related to the weather. Generally, it takes at least 60 minutes; when it is cold, it takes 90 minutes.
2. Way of curing
The curing method is different in different factories.
Some are using two large iron plates sandwiching a quartz slab;
(this method ensures that there is no deformation during curing.
After the curing oven comes out, some patterns, like black colors, still need to be clamped by auxiliary tools to avoid deformation during cooling.)
Some directly heat by electricity, and then after the curing oven comes out, the slab is clamped by auxiliary tools so that it will not deform during cooling. (But in the oven, it may deform.)
3. Cooling time
If the weather is hot, it should be cooled for at least half a day; if the weather is cold, it should be left open for one day to cool the slab. And then it can go to the polishing process.
4. Slab storage way
The slabs must be placed in the warehouse correctly.
Because of a lot of calacatta quartz, Carrara, including pure color fine-grained quartz stone, the amount of resin will be higher than the coarse-grained quartz stone.
If the placement is not correct, the proportion of deformation will be higher.
