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.
