There are many different types of Agate depending on
the colors and formation. Common types of agate include blue agate, moss
agate, green agate, tree and wood agate, Indian black agate, Montana
agate, banded agate, red agate, graveyard point agate. A Mexican agate,
showing only a single eye, has received the name of cyclops agate.
Included matter of a green, golden, red, black or other color or
combinations embedded in the chalcedony and disposed in filaments and
other forms suggestive of vegetable growth, gives rise to dendritic or
moss agate.
The fake agate is synthetic, part of them are act as a
high-quality stone. Its basic features are: Though it has cool
handfeel, but there is no waxy feel and gloss. Some of the hardness is
low, It is not easy to Score the agate with a knife . broke it and
observed the cross-section, in addition to it has not the laminated
structure, granular-roughened or hispidulous;Check for any gaps. Opaque,
the color is clear-cut. Some unscrupulous traders glue a thin layer of
organic on the surface of fake agate, it will giving a waxy luster and
good feeling .This gives a person a kind of illusion. Meantime, The name
must not let confuse an eye when buying, must notice to distinguish.
Please Careful selection .
First, the larger the printing area, the lower the box's resistance to stress. Secondly, when the printing area is equal, foreign packaging researchers researched (see Figure 3): when printing for the first shape, the empty box can withstand the pressure drop of 28 to 36%; When the two shapes are printed, the pressure resistance of the empty box of the carton can be reduced by 12 to 25%; when printing for the third shape, the pressure resistance of the empty box of the carton can be reduced by about 5%. Especially in the case of full-scale printing and circular belt-shaped printing in the first case, the impact is most pronounced.
The reason for this is that the printing pressure causes the corrugations of the carton to be deformed, thereby reducing the pressure bearing capacity of the corrugated carton. And the larger the printing area is, the greater the damaged area is, the worse the pressure bearing capacity is, resulting in the reduction of the pressure resistance of the carton empty box.
However, with the continuous improvement of printing equipment and printing technology in the carton industry. The degree of influence in this area has been greatly reduced. (image 3) 
In our daily life, we often see home appliances cartons and food cartons. These cartons have hand holes and vents on the wall. What effect does the presence of these holes have on the pressure resistance of the carton's empty box? Studies have shown that the transverse hand hole has a greater effect on the carton's resistance to pressure than the longitudinal hand hole. The hand hole should be as small as possible, as close as possible to the center of the carton so that the impact can be minimized.
What has been mentioned above is the impact of the box design on the pressure resistance of the empty carton box, in addition to the carton forming process, which is related to the manufacturer's equipment. Workers technology. It mainly includes: chamfer slotting of cartons, binding and binding of cartons.
In summary, it can be seen that there are many factors that affect the carton's resistance to pressure. In order to increase the strength, we should focus on comprehensive evaluation in order to achieve the best results with lower costs. Of course, the direction of development in the future is to use computer-aided design. In the computer, elements such as design ideas and printing requirements are input as input, and then the best empty box compression effect is sought. (Text / Zhang Xiaorong Jiang Wei)
How to identify and choose the agate?
Agate is a kind of gemstone jewelry ,the jewelry which produced by
agate is quite popular with women. But How to identify the true
agate?Please according to the following rules.The symbol of the
difference between Natural agate and false is there has cross-sectional
structure of a layer of grain, Make use of this flag, agate
will be very easy to identify. The finished products after cutting,
because there is no obvious pattern neatly, so it's easy to confuse the
two. But generally speaking, natural agate has cool feeling, like a
painted surface, a layer of wax and a wax luster, translucency, It's the
hardness of the Moroccan 6-7,Even it will not scratch if use the knife.
Because it is in the molten state to form crystals, so mostly of them
are spherical, the internal structure of the nature agate is tighter.
After grinding the surface is more delicate, rough wood and agate for a dramatic friction, instant, the agate is
not fever, but wood will burning. It Is often mixed with a variety of
colors, forming a beautiful pattern, such as the flowery one or the
striped one.
2, texture: most of the fake agate are made of imitation stone ,The Texture is more softer than the real one. It is easy to Score the fake agate with a knife , and It is not easy to Score the real one with a knife. On the surface,usually the real one has pure without any defect. The more expensive an item is the more carefully we should examine it for faults.
3, Transparency:The Transparency of the natural agate is not as good as the synthetic one, it is a little chaos in it.But the transparent of the Synthetic agate is good as glass balls.
4, weight: the weight of real agate jewelry is higher than synthetic agate.
5, temperature: the real agate is cool in summer and warm in winter, but the temperature of fake agate isn't maintained internally the way it is, but fluctuates with the temperature of their environment.
