the common problem of quartz stone countertop

一.crack of the quartz stone countertop:

1.common crack situation:

⑴crack of the joint of the quartz stone countertop⑵corner cracking of the quartz stone countertop⑶cracking of furnace hole perimeter⑷cracking of black splash⑸cracking of the connection between the black splash and quartz countertop⑹Cracking in the center of the quartz stone countertop；

2、reasons for the cracking of the quartz stone countertops

⑴.crack of the joint of the quartz stone countertop: joint is unaligned when the worker joint two piece of the quartz stone countertop, or cut the quartz stone countertop as a mouth of a horn, which on side is bigger than the other side , or don’t spread the glue evenly and more important is don’t clip the quartz stone countertop or don’t clip tightly after spreading glue , or add excess curing agent and accelerator to the glue when do joint to make the joint is brittle and will be easy to crack by a slight impact cracking;

⑵.corner cracking of the quartz stone countertop: too close to the wall without any shrinkage space, or the two cabinets is rugged, or make before turning into a right angle, then the quartz stone countertop will be easy to crack by external shocks or changes in temperature;

(3).cracking of furnace hole perimeter:There is no gap between the gas stove and the stove holes, or the holes are not polished smooth, or the basin hole are not worn round or have serrated marks, then the quartz stone countertop will be easy to crack by external shocks or changes in temperature;

(4).cracking of black splash: The cabinet or the support plate is not even or smooth:

(5).cracking of the connection between the black splash and quartz countertop: Glue is not firm;

(6) .cracking in the center of the quartz stone countertop: Because of high temperature, external shocks, cabinets or support plate is uneven or the quartz stone slab is internal injury etc.;

二.quartz stone countertop is deformed

there is part deformation occurring of the quartz stone countertop, the main problem is the quartz stone slab is soft, or there is no shrink space when install the quartz stone countertop in and so on; all of these is due to the quality of the quartz stone slab and fabrication quality;

三. color change of the part of quartz stone countertop

A: deep color or light colored quartz stone slab color changes as they dipped in water or colored liquid, deep color quartz stone slab will variable light or whitish, and there will be water mark on the surface of light color quartz stone slab. This is mainly caused by poor quality of filler of the quartz stone slab; another situation is quartz stone slab is exposure to sunlight for prolong time and then the quartz stone countertop will be color changing. This main reason of this is the anti UV ability is of the quartz stone slab is worse, because of pigment is instability, poor quality.

tips of operating the quartz stone fabrication machine

it is better to follow certain procedures during the operation of the quartz stone cutting machine.

1 during the fabrication, it is better to inspect and supervise the cutting conditions, and deal with or solve it immediately if there is any problem.

2 when programming, should be according to the real situation to determine the correct fabrication technology and fabrication route, to avoid the fabrication position is insufficient or take edge strength is not enough and the work piece of quartz stone scrapped in advance.

3 checking whether the jet selection is reasonable, with high pressure jet flow when rough machining, with low pressure jet flow when finish machine.

4. moving workbench or spindle should be according to the distance with the work piece of quartz stone. Taking the correct moving speed and take strict precautions against moving too quickly to avoid the collision occurred.

5 to check whether the feeding speed of the electrode wire is appropriate.

6 lines cutting must be confirmed before the procedure or the amount of compensation is correct.

7 before the cutting, should pay attention to observe the fabrication stability, and timely adjustment of bad.

8 according to the real situation of the fabrication parts of quartz stone, to choose the open machining or close processing, in the premise of avoiding interference as far as possible to shorten the distance between the nozzle and the fabrication parts of quartz stone.During close process, the distance between the nozzle and the fabrication parts of quartz stone is generally 0.05 ~ 0.1mm.

9 checking the wire tension is sufficient. In taper cutting, usually turn down the tension to the half tone of normal.

What thickness of Quartz Stone is better for countertop

The other day, discussed with our colleague about the thickness of Quartz Stone for countertops. What thickness is better for countertops?

As we know, there are several kinds of thickness of quartz stone,12mm,15mm,18mm,20mm,

30mm, but which is better? In domestic area, many Property developers are prefer to use the 12mm Quartz Stone for countertop to save the cost. However, actually, 12mm Quartz Stone slab is easy to break as Quartz Stone is brittleness itself, and 12mm Quartz Stone will can bear lower impact. Then which thickness of Quartz Stone is better for countertops,15mm,18mm,20mm or 30mm? as we discussed, and find out, 18mm or 20mm may will be better for the quartz stone to be used for the countertops. As 18mm and 20mm ones is thicker than the 12mm and 15mm ones, so 18mm and 20mm quartz stone could bear more impact, at the meanwhile, 18mm and 20mm is little thinner than the 30mm Quartz Stone, this will make the 18mm or 20mm Quartz Stone to be much lighter than the 30mm Quartz Stone, then will be much safer when there is some impact or concussion. Also, as 18mm or 20mm Quartz Stone is thinner than the 30mm Quartz Stone, so will be easier to be fabricated and could save the cost.

Our Quartz Stone and Acrylic Granite Sink

As we know, Quartz Stone is made from natural Quartz and little resin. and we also have the product Acrylic Granite Sink, also knew as acrylic quartz sink. Then,sometimes, customers are curious whether the material for acrylic quartz sink is same as quartz stone. Actually, the raw material for making quartz stone is same as acrylic quartz sink, but the content of the raw material is different for this two kinds of product. Raw material content for quartz stone is 93% natural quartz and 7% resin, but the content of raw material for acrylic quartz sink, is about 20% resin and 80% natural quartz. Because the raw material for acrylic quartz sink have to be pour into the stainless steel mould, so the mixed raw material should be fluid and easier to be modelled, then the resin content have to be higher. So the hardness of acrylic quartz sink is well, but is not as high as quartz stone. However, the acrylic quartz sink is still with excellent performance and also is more and more popular.
