1) Construction paper
For the special paper used in construction, the "paper construction" used in the Sydney Olympics can be cited as an example. The gypsum paperboard, tar paper, wallpaper board, etc. used in the past cannot be compared with the new construction paper of today in terms of strength, rigidity, and waterproof performance. In addition to plant fiber paper, the new construction paper also uses polymer compounds.

2) Wear-resistant layer paper for composite floor
In recent years, my country has introduced a large number of composite floor production lines, and the demand for composite floor surface layer wear-resistant paper is increasing. The weight of wear-resistant paper is 30-60g/m2, the roll width is about 1300mm, and the paper has high tensile strength and moisture. Good wetness. The raw material is long fiber, and when it is laminated with other material resins, it has good body absorbency. Composite flooring has gradually become a new variety in flooring products, and it requires the collaboration of professional material supporting manufacturers. With the increase in the amount of laminate flooring, the added value and profit margins of wear-resistant paper are greater. Now is a good time to research and develop wear-resistant paper.

3) Color axis cotton brick lining paper
Color axis cotton brick is a new type of building decoration material that makes various buildings more magnificent. The decorative lining paper for bonding the color axis cotton brick can improve the production efficiency of the cotton brick, and it can also facilitate the construction on the construction site. This kind of backing paper looks the same as ordinary paper from the outside, but has a special physical index. It not only requires a certain dry and warm strength, but also must have good water absorption properties.

4) Paper steel
Paper steel is a contemporary high-tech achievement. It is a new type of building material made by papermaking methods by mixing extremely fine metal wires and fibers in pulp, also known as metal fiber paper. The thin one is only a few tenths of a millimeter, as thin as paper, but the strength is equivalent to steel; the thick one can be made of several layers of thin paper and steel sheets bonded with synthetic resin, and the thickness is 2-3 cm. Paper steel can be made into plates, and can also be stamped and rolled into grooves, waves and various special-shaped materials.
Once paper steel came out, it showed strong vitality and broad prospects. It has played a wide range of roles in industry, agriculture, construction, national defense and military industry, and daily life. Foreign countries have used it to make the inner wall materials of cars and trains and aircraft fuselages. Lightweight houses made of paper and steel can be assembled and transported and are suitable for temporary workshops, classrooms and camping houses. The United States has used paper steel to form a paper bridge with a span of 15 meters and a bridge deck of about 3 meters wide. It can not only pass pedestrians, but also small tractors and 2.5-ton jeeps, and it can be disassembled and installed. The paper and steel materials used to build a bridge can be transported away in a Jiefang brand car, so it is very suitable for military use. Thin paper steel is as light and soft as gauze and plastic cloth, and can be used for daily necessities such as tablecloths, curtains, and sheets; thicker paper steel can be stamped into various utensils, such as bowls, basins, boxes, etc. All plastic products can be replaced by paper steel and will not age. Paper steel can also replace wood to make chest of drawers, wardrobes, boxes and other furniture.

5) Various new wallpapers
A heating wallpaper
Britain has successfully developed a wallpaper that can radiate heat. This kind of wallpaper is coated with a special paint coating. The coating can convert electric energy into heat energy after being energized, and emit heat, which is suitable for pasting in winter.
B Hygroscopic wallpaper
Japan invented a moisture-absorbing wallpaper. The surface of this wallpaper is covered with countless tiny pores, which can absorb 100ml of water per square meter. It is an ideal decoration for the wall of the bathroom.
C Anti-mold reproduction wallpaper
Japan has developed a wallpaper that is difficult for mold to reproduce. This kind of paper is made of polyvinyl chloride resin, which is the raw material of the wallpaper, with an anti-mold agent. The paper not only improves the living environment, but also benefits people's health.
D insecticide wallpaper
The United States invented a wallpaper that can kill insects. As long as flies, mosquitoes, cockroaches and other pests come into contact with this wallpaper, they will be quickly killed, and its insecticidal effect can be maintained for 5 years. This wallpaper can be scrubbed and is not afraid of water vapor and chemicals.
E sucking wallpaper
The odor-absorbing wallpaper developed in Japan has certain chemical substances, which specifically absorb and decompose some peculiar smells, and are mixed with aromatic substances, so that the room is always fragrant, especially suitable for kitchens and toilets.
F Fire Alarm Wallpaper
The United States has developed a fire alarm wallpaper, which has been used in many hotels. This kind of wallpaper will emit an odorless, colorless and harmless gas under high temperature and fire, which will trigger the ion-type smoke detector to send out a fire alarm, and then activate the fire extinguishing device to extinguish the fire source.
G anti-eavesdropping wallpaper
Germany has developed a wallpaper that can prevent electromagnetic interference and electronic eavesdropping in the room. It is made of nylon non-proof cloth and copper skin, and the screen performance is better than steel and galvanized iron skin, and it is not easy to be noticed.
H high shielding wallpaper
Britain has developed a high-shielding wallpaper, which is nickel-plated on the surface of carbon fiber, which can completely shield highly sensitive electronic equipment from electromagnetic waves and high-frequency noise interference, prevent electronic reconnaissance activities, and its shielding effect can match steel walls. , And can be pasted with ordinary adhesive.
I Non-combustible paper
Japan issued non-combustible paper using calcium silicate as raw materials, which can be used as wallpaper and heat-resistant fillers. During manufacturing, silicic acid powder reacts with lime water through heat to extract fibrous calcium silicate, and then add glass fiber and paper reinforcing agent. Non-combustible paper can replace asbestos materials that are restricted due to environmental issues.
