Q: What is the function of the cardboard in the reflection of light?: The reflection of light refers to the phenomenon that the light changes its direction of propagation and returns to the original substance when it travels to different substances. Light reflects on the surface of water, glass, and many other objects. The phenomenon that light changes its direction of propagation at the interface of two substances and returns to the original substance is called the reflection of light.

Q: What is over printing paper?: Printing paper is a kind of paper that is often used in offset printing. The use of printing paper is also a way to reduce the cost of printing.

Q: Excuse me, how to calculate the weight of honeycomb paperboard, I have a formula but not sure, thank!: The core paper area consumed by honeycomb paperboard per unit area is S=1.9*t/c. (t is honeycomb panel thickness, C is honeycomb side length). Taking area multiplied by core paper weight is core paper weight

Q: Why will the paperboard be warped during the production of corrugated paper?: Corrugated paper is made of multilayer base paper (paper, inner paper and middle grade corrugated paper). In the process of production, the paste should be added between the layers.

Q: What kind of cardboard do you have?: Paperboard for industrial use, such as electrical insulating pressboard, asphalt waterproof paperboard, etc..

Q: What's the size of the 14 paper opening?: Specifications for printing paper:The size of the paper refers to the paper made after, after finishing cutting, cut to size. In the past, how many "open" (such as 8 open or 16 open, etc.) to represent the size of the paper, and now I use international standards, the provisions of A0, A1, A2, B1, B2, and other marks to indicate the format of the paper specifications. Standard paper width (X) and length (Y) ratio is X:Y=1:1.42.In accordance with the basic area of the paper format, the format specification is divided into A series, B series and C series, format specifications for A0 size is 841mm * 1189mm, surface area of 1 square meters; the B0 size is 1000mm * 1414mm, surface area of 2.5 square meters; C0 format ruler inch 917mm * 1279mm format, an area of 2.25 square meters; the format specifications of copy paper by A and B series. If the A0 along the length of paper into two parts, will become the A1 specification, the A paper along the length direction of, will become the A2 specifications, so to open to the A8 specification; B8 paper also according to the method of opening to B8 specifications. The sizes of A0 ~ A8 and B0 to B8 are listed in the following table. The A3, A4, A5, A6 and B4, B5, B6 7 format specifications for copy paper commonly used specifications.

Q: How are the quality of the paperboard separated?: I can see that no matter what kind of paper or cardboard there is a positive and negative points, in the paper, the wet paper and net contact surface is opposite, and the other side is positive. On the contrary, because of the contact with copper net, the small fiber and packing loss more, showing screen printing, so the opposite is more rough. There are obvious differences between the positive and negative aspects. The smooth, positive negative is higher, more negative than positive picking speed; white tails better than positive, therefore has two sides of paper and paperboard.

Q: What is fluorescent paper?: Fluorescent paper and plain paper itself is not luminous in the dark, so they are black. In the sun, when light irradiates on plain paper, paper put the light reflected, but also the ultraviolet reflected light reflected from the eye can see, but can not see the ultraviolet ray;

Q: What's the difference between coated paper and offset paper?: In brief, the difference between the two is that both sides of the copper sheet are coated, and the offset paper is not. Offset paper, the base paper of coated art paper, is uncoated coated art paper.It can not be simply said that coated paper is better than offset paper. If so, offset paper will be eliminated by coated paper. Offset paper is suitable for his market, such as all monochrome text type books, or color printing of the rough paper effect of the offset paper.And then the same weight of offset paper, usually cheaper than coated paper. Different prices, different characteristics, each has its advantages.

Q: What is the difference with the white paper board, is that they are the same paper?: The white paper is a positive is white and smooth, the back is the ash bottom board, this board is mainly used for single-sided color printing carton packaging made for use, or for the design and handicrafts. White paper is composed of surface layers in the slurry and the bottom slurry multi cylinder paper machine dryer or multi combination the cardboard machine is made. The slurry is generally divided into Mianjiang (surface layer), two layers, three layers and four layers, each layer of pulp fiber ratio is different, and each layer of fiber proportion, according to the quality of the copy paper are different. The conventional white paper weight: 230 g/m2250 g/m2270 g/m2300 g/m2350 g/m2400 g/m2450 g/m2500 g/m2.
