Points to be
noticed for the purchase of the ceramic wall tile and floor
tile
Ceramic bricks, for its various colors and sizes, are well
popular by people. See its glazed surface at first when choosing, glazed
surface should level, smooth, fine, sparkling and crystal, the matte
should soft ; See specification secondly, high-quality brick specification
deviates little, the size is unified , the corner does not have defect ,
at right angle of 90 degrees; Moreover see the pattern, the high-quality
brick pattern is clear and lifelike, there is no obvious phenomenon which
is short of color.
When choosing the ceramic brick it is necessary to
distinguish the difference between ceramic and porcelain quality , it
mainly differ in water absorption, the smaller the water absorption is,
the more close the structure is, the sound is clear and melodious while
beating, this is a porcelain quality brick; While water absorption is
higher with many structure holes, tedious sound when beating , that is
ceramic quality brick. You can choose ceramic quality brick of lower water
absorption, the crackle doesn't appear while changing in temperature.
Check geometric measurement
Whether the geometric measurement is standard is the key to
judging good and bad quality of ceramic tile . Can measure diagonal, four
side sizes and thickness and see if it is even so as to judged the brick
when choosing.
Compare chromatism
Can unpack and spot check several at random , place one oe
place to compare one by one together. Generally very slight difference is
normal, but it is problematic to be very obvious. But different ceramic
tiles which produces in different lot number will have colour difference,
so you'd better buy enough quantity once , otherwise it will difficult to
have same colors afterwards.
Simple Testing Method
Can drip a
droplet of ink on the brick surface, if the ink spread and soaked out
quickly, namely shows that he brick density is relatively bad , the
permeability is strong , quality is not good, on the contrary, if the ink
is dripped and does not move in the original place, proves that the brick
density is good, quality is better. Watch carefully its testing surfaces
is apt to leave scratch for brick (especially glazed tile, imitate Spanish
brick ,etc.. ) or not; Watch whether factory's name , brand , grade , lot
number are unanimous on the packing box of the product carefully.
Method of Choosing ceramic brick
Glazed surface
The glazed surface should be smooth ,
fine; Gloss glaze should be crystal and glossy, unglazed glaze should soft
, comfortable. Put several pcs of ceramic tiles together and watch
carefully under the light , the good products' colour difference is very
little, the tone between the products is unanimous basically; And the bad
products' colour difference is relatively big , the depth of tone differ
between the products
Polished brick
Can use the caliper to measure . The good
product specification deviation is small, after paste, the products are
uniform, the joint of brick is strought with good ornament result. The bad
product specification deviation is big, the size is not uniform in the
products. Can observe directly with the naked eye . Require the smooth
face and smooth surface, in this way the products is at the low rate to be
out of shape, construction is convenient, the brick is smooth and
beautiful after installation.
Porcelain tile
The floral pattern should be fine and
smooth , lifelike , no obvious defect of lacking the color, breaking ,
misplacing etc.. The tone of the wall brick should keep coordinating with
the surrounding environment , the high-story building should not generally
decorate bricks with the white or overly light-colored outer wall
decorative brick first , in order to avoid making the building lack the
quality feel; In interior decoration, the tone of ceramic tile and
interior wall brick should form a complete set each other. The bathroom
will rely mainly on cleaners, the quality, grade of wall tiles, floor
tiles, and various kinds of fittings include hardware and other related
materials should all be in harmony with it.
Expert answers your
questions?
Q
: Does the vitrified polished brick have any strong point,
shortcoming?
A : Compared with stone material, the
vitrified polished brick has such several advantages
1 , The
hardness is high, its index reaches 8 degrees;
2 , The
glossiness can be up to more than 80 degrees of surface of the
mirror;
3 , Does not need to maintain ; the vitrified polished
tile is simpler than the stone material for maintenance, and less
trouble. 。
4 , The colour difference of the natural stone
material is more serious, the vitrified polished brick will not has
colour difference, and can accomplish the color unanimously.
5 ,
The stone material produces radiation, the radiation of the known
brand vitrified brick is very little.
Q : Is it that a glazed tile is
good or is the vitrified brick good to be paved on the ground of
sitting room?
A : The working environment in the sitting
room is fewer influenced by temperature, pollution , it is
comparatively better environment, so it requests not very high to
ceramic tile material of itself, the only thing need to notice is
that select the concrete design according to light, individual taste
of sitting room; Additional for the ceramic tile in the sitting
room, considering there are many people coming in and going out, you
had better select the products of some known brands , its hardness
of surface is relatively high, and will be more secure, not easy to
scratch. In term of present social trend, select the ceramic brick
in the sitting room mostly. The glazed tile is used in the bathroom
and kitchen more.
Q : Whether the vitrified brick
needs to soak with water before being laid , if necessary, how long
does it need to soak?
A : It is unnecessary to soak with
water. It is all right to pave it directly.
Q : I want to know what type of
cement you used to pave the ceramic tile now ?
A : For
general inner house you'd better use the cement below No.425, if the
cement grade is too high, the result is not very ideal, especially
the quality that some small factories produced is not the cement
reaching a standard very much, sulphur content exceeds standard, the
brick surface will leave some defects , so it is a little better to
use the cement of the low grade. For outer wall brick you had better
select high grade cement when paving , can add some glue , increases
the compositions to resist coming off.
Q : Should ceramic tile in bathroom
be dryly pave or wetly pave?
A : it should be wetly paved
Q : Which kind of ceramic tile's
warm-resistance better? Which kind of ceramic tile's wearability is
better? Ask experts to introduce.
A : If from the class
of ceramic brick's manufacturing, the glazed tile is better for
dirt-resistance, in term of wear-resisting, the vitrified brick
wearability is better.
Q : After the ceramic tile is paved
well, is there any standard to confirm?
A : Main points
of confirmation methods :
1.use level paper to measure it and
see if the brick joint to be a line , unanimous in same size.
2.Step on it and see whether there are some noises partly. The
reason to cause it is that the cement can not be daubed evenly, so
it will have some places to be empty when stepping step on.
3 ,
Examine the joint see if it is even. When paving it should pay
attention , the cement should be wiped in time while filling. Paving
confirmation has something to do with quality of the ceramic tile in
addition, the cement does not totally finish inherent concreting
course when paving. You had better confirm the ceramic after the
cement intensity executes totally , see ceramic tile if it can split
open in twenty days. |
