How do we deal with the toxic players?
When it comes to what materials to use to
decorate the house, the first idea that comes to mind is that it's ceramic
tiles. However, because there are many kinds of ceramic tiles in the building
materials market, most consumers do not know how to choose the tiles,
especially in the choice of tile color. They do not know which color is
suitable for their own home. If you have the same question, let's understand it
together.
1. White and gray
White and gray are the most popular and
popular types of ceramic tile products this year. Because the application of
gray and white ceramic tiles is relatively versatile, and there is not much
attention to architectural decoration, it is also the common choice of many
designers and home decoration owners.
2. Warm colors
Warm color tiles give people a full sense
of warmth, but also more grounded, warm color occupies a large proportion in
the traditional Chinese home style, its low-key decorative effect can make the
overall building space become very harmonious, at the same time, not out of
style and noble, fashionable.
Ceramic tiles are also the basic elements
of building construction. When ceramic tiles are perfectly combined with various
accessories, the home space can become more artistic and cultural. All kinds of
metal home objects are the standard of modern home space. More fashionable
furniture also adds different visual senses to the space.
3. Brown, dark grey
Brown, dark gray tiles, will never miss a
visual feast, they are unrestrained, rough crazy, personality, they are a
wonderful interpretation of every architectural space, but also more like a
unique existence, not how dazzling, just for the real essence of the decoration
effect.
4. Dark color system
Heavy color ceramic tile, with strong color
expression, is the ultimate pursuit of personality, and also a new definition
of the effect of new decorative space. The more forward-looking expression of
color space decoration is a higher respect for architecture, breaking through
the space application of traditional color system, which is a higher level of
subversive visual application innovation and concept sublimation.
Therefore, whether it is warm, bold or
rough crazy, or even personality, in the use of tile color can be shown.
Ceramic tile can not only make every inch of space full of a stronger sense of
art, but also decorate the space with more company. The application of ceramic
tile decoration is a complete system, and it is also a kind of artistic
expression and creation that can give full play to imagination. Choose a good
tile, decorate a good mood.
The popular fashion Brazilian human hair bob wigs style is very popular with many beauties, but they are willing to cut
their own hair. Fortunately, wigs can meet the needs of beauties. Now let's
learn the skills of wearing long hair wigs. Soon you can also wear super
fashionable wigs out of the street.
If you want to change your hairstyle
frequently, but don't want to hurt your hair, it's wise to wear wig. If you
want to wear it well and vividly, let's learn from the makeup artist!
How
to wear wig cover
When wearing it in front of the mirror,
first comb your hair, hold the sideburns of the wig cover in both hands. When
you start to wear it on your head, you should be slightly forward. When you
have worn it in the mirror, press your head with both hands to make the wig
cover move backward to the appropriate position. First fix the front face, and
then fix the back. According to the width of the forehead, wear it in the
appropriate position. If it is fixed with clips, just press the two ends of the
clip to fix it. Wide forehead, long court, slightly pull down the edge of wig
when wearing; Narrow forehead, short court, when wearing, wig edge slightly
upward, but not too upward. It's better to use the headgear tightly at the
initial stage, because the headgear will be looser than before after a long
time. If you want to take it off, you can take it from front to back.
1. Divide your hair into two or more bundles (according to your hair size and length)
2. Braid the separated hair into braids,
then fix the hair behind the head with clips
3. Then put on the hair net (used to net
your real hair) and don't run around. Short hair can be directly with hair net)
4. Put on the bob wigs and comb, the beauty
is finished
MM are in dish hair when don't braid a good
plate in the head, because this plate out of the place will drum Oh! You can
use more clips to clip the clothing. You may feel a little troublesome at the
beginning, but you will get used to it immediately. M's take time to slowly
clip a little patience.
The heat treatment process of cast aluminum
is composed of three stages: heating, heat preservation and cooling. The whole
process can be described by several parameters, such as heating speed, heating
temperature, heat preservation time, cooling speed and heat treatment period.
In each heat treatment process specification, temperature is very important. If
the temperature measurement is not accurate, the heat treatment process
specification can not be correctly implemented, which will cause the quality of
aluminum castings to decline or even scrap. Temperature measurement and control
is the key of heat treatment technology and the key factor affecting
deformation. The influence of cooling process on deformation of aluminum
castings after quenching is also an important reason. After the metal heat
treatment, the thin part is always cold fast and the thick part is cold slowly.
In order to reduce the distortion and cracking tendency of transition zone due
to stress concentration, the difference between thickness and thickness of
workpiece should be minimized when the actual production needs are met. After
heat treatment, aluminum castings are processed. According to the deformation
law of the castings, reverse deformation and pre expansion holes at the shrinkage
end are applied to improve the qualified rate of deformation after quenching.
1、Datum selection
The datum plane must be determined for the
selection of elements, the dimension inspection of the die cavity, the marking
of the casting and the machining of the die casting. The outer circle, plane, inner
hole and end face of the casting can be used as the reference plane. The
appropriate datum plane is generally agreed by design, processing and casting.
The following points should be considered when selecting datum:
a. the non machined surface is generally
selected as the reference plane of the investment casting. If the machining
surface is selected, it is better to select the surface with less machining
allowance.
b. the datum shall be selected with the
surface with precision requirements between the surface to be processed, and
the design datum and processing process datum of the parts shall be coincident
as far as possible.
c. the number of datum plane shall be
restricted by six degrees of freedom, so generally three base surfaces (two
base surfaces are selected for rotating parts) are generally selected, and the
line marking and processing shall be the same base plane.
2、Structural design of cast aluminum parts
Whether the structure of castings is
reasonable has great influence on the quality of castings, the feasibility and
simplicity of production technology and the production cost. The structure of
the investment casting should conform to the production characteristics of the
investment casting. The example of the reasonable structure of the part of the
casting is shown.
In order to ensure the quality of the
casting, process ribs and process holes are often set on the casting according
to the needs. The example of application of process rib is shown. The reference
dimensions for the process rib design are shown. The application example of
process hole is shown.
The casting of the molten metal can be used
to cast complex parts. In order to improve productivity and improve accuracy,
the assembly and weldment of several parts produced by other methods can be
directly cast into a molten casting after slightly structural improvement. The
structural example of the multiple parts assembly and welding parts changed
into the whole casting of the molten mold is shown.
3、Selection of casting structural elements and process parameters
Small wall thickness: because the inner
surface of the mold shell is smooth and dry, and it is generally poured by hot
shell, the wall thickness of the investment casting can be designed thinner.
The recommended values for small wall thickness and the possible small values
of the various alloy casting are shown. For local parts, thin wall thickness
can be cast, which is 30% - 50% smaller than the small value in the table.
The application range of zinc die casting is
universal. Aluminum casting is one of the metal forming methods, which is the
way to complete the process of less chip and no chip. It is widely used and
developed rapidly. At present, die casting alloy is no longer limited to zinc,
aluminum, magnesium and copper of non-ferrous metals, but also gradually
expanded to cast iron and steel castings. The size and weight of die casting
parts depend on the power of die casting machine. Because of the increasing
power of die casting machine, the shape size of casting can be from several mm
to 1 ~ 2m; The weight can range from a few grams to dozens of kilograms. Die
casting is no longer limited to the automotive industry and instrument
industry, and gradually extends to other industrial sectors, such as
agricultural machinery, machine tool industry, electronic industry, national
defense industry, computer, clock, camera and daily hardware industry. In the
aspect of die casting technology, new technologies such as vacuum die casting,
oxygen injection die casting, precision and density die casting and application
of soluble core are presented.
