Q:What is the lower formaldehyde content of solid wood furniture than plate furniture?
Solid wood furniture, formaldehyde content than the number of low-grade furniture, no specific indicators, generally much lower.
Mainly affect the formaldehyde content of solid wood furniture is the paint part. Formaldehyde mainly from the glue, adhesives, paint and other processing to the part.
House decoration because of formaldehyde and other factors caused by very hot eyes, the air is not clear and other conditions, solutions are:
1, ventilation, vacant for some time.
2, put in the house rotten apples, activated carbon, the effect is very good.
3, you can find a clear clear formaldehyde cleaning company.
4, put some flowers, you can absorb formaldehyde, but the flowers on the sacrifice.
5, the best way is to place 3 months, so that formaldehyde volatile.
Q:How to do the corn stalks
Process Technology Line:
1. Straw density plate:
Air dry straw → impurity removal → cut off → wind selection (blown out of the heart) → cans → high pressure steam → spray → fine → spray → drying → pavement → preload → hot pressing → edge → cutting → packaging → finished product
2. Straw crushed plate (particleboard)
Drying Straw → Cutting → Wind Selection → Recovering → Drying → Screening → (Surface Layer, Dust, Core Material) → Mixing → Pavement → Preloading → Hot Press → Edge → Cutting → Inspection → Packaging
3. Straw composite board
Straw → Cutting → Steam Blasting → Mixing → Paving → Wood Veneer → Glue → Preloading, Hot Press → Side → Varnish → Sanding → Finished
4. New wall materials:
Corn stover high grain straw → election → leaves → cut → pavement → irrigation → do the surface layer → veneer → sanding → finished
In addition to the above processing, the straw can also be used for pulp making after steam blasting, which is about a third less expensive than traditional pulping methods and only one third of the traditional method. It is helpful to solve the problem of pulp gap caused by the forced cessation of small papermaking by the state.
Fourth, the main technical key and expected to achieve the technical and economic indicators:
1. Main technical key:
① developed as low as possible, environmentally friendly, waterproof superior, infiltration of a good name of the glue.
② design and improvement of grading pavement.
③ steam blasting equipment selection and the determination of the main process parameters.
④ hot pressing and cold pressing process parameters adjustment.
2. Expected technical and economic indicators:
① adhesive; solid content: 60% -65%
Free formaldehyde content: 0.2% or less
Viscosity: coated with 4 cups: 30 ℃ 10-20 seconds (fiberboard)
50-65 seconds (particle board)
Q:How can the wood on the wood directly on the paint ah?
Of course, ah, you use the wood is fresh? You go to paint stores, in general, big treasure and China Resources Wooden paint or can, where to ask the professionals on the OK
Q:Decoration used plate, and asked the price of three thousand square plate how ah
There are some quality of the plate although meet the requirements, but they are more complex processing technology, such as your paint to waste some of the amount, or not strong and so on.
Q:A5052P ー H34 aluminum alloy sheet number and the meaning of what is the letter?
A5052P rust-proof aluminum alloy, chemical composition%:
Si Fe Cu Mn Mg Cr Zn
0.25 or less 0.40 or less 0.10 or less 0.10 or less 2.2-2.8 0.15-0.35 0.10 or less.
5052 for the aluminum alloy grades, it is magnesium alloy (5xxx series are magnesium alloy) one of them, can solve the work hardening, strength comparable to steel. The alloy has good forming processability, corrosion resistance, can be candle, fatigue strength and moderate static strength, used in the manufacture of aircraft fuel tanks, tubing, and traffic vehicles, ship sheet metal parts, instruments, street lamps and rivets, Metal products and so on. "-" The subsequent H indicates that the work hardened state is suitable for products that are enhanced by work hardening, and the product can be subjected to an additional heat treatment that is reduced (or may not) after work hardening.
Commonly used aluminum
7075 aluminum alloy plate, 7075 aluminum alloy tube, 5052 aluminum alloy wire, 6063 aluminum coil, 2024 aluminum alloy rod, aluminum alloy profile.
GB / T3880-2006 "general industrial aluminum and aluminum alloy plate, strip"
GB 5237-2004 "aluminum alloy construction profiles"
Q:What are the advantages and disadvantages of using solid wood and blockboards (tatami)
What are the wood materials for tatami
To make the material of the platform can be used Paulownia, oak, the Russian barrier pine finger board, Ou Song board, fir finger board, Daxing board refers to the board, mostly with pine and fir, individual above the cork, OKorder fashion classic Tatami recommended cost is higher than the general use of Russian Pinus sylvestris, inside with fir, do not advocate with Daxin board, woodworking board, sauna board and so on.
We do not use a large core board, the general use of pine or fir, if the economy allows, you can consider oak and so on.
Pine appearance soft, delicate texture, fresh taste; Chinese fir scars, woody taste more exciting, it is recommended as the site can not see the place.
OKorder fashion classic and room tatami decoration, is committed to the use of Chinese living space and reasonable to build
Q:Is the epoxy sheet toxic?
Strictly speaking, epoxy sheets are toxic. But the toxicity is very weak, are the actual non-toxic products.
Because, simple epoxy resin is environmentally friendly non-toxic, but usually it is necessary and the use of curing agent, curing agent are generally some toxicity, modified amine curing agent can only be low toxicity, completely non-toxic impossible. Other types of curing agent are some toxicity, but the extent of a different, but basically are low toxicity. Where is the organic products, how can the toxicity of no Yeah, after curing epoxy glue no toxicity, it can be said that toxicity will not be higher than other plastic products Therefore, the epoxy resin sheet in daily life, is classified as the actual non-toxic products.
Q:The overall price difference between the overall wardrobe on the market, the plate is really a lot worse?
Q:Woodworking four meters of the cabinet to a few sheets
Cabinet fire board needs an area of 9.4 square meters (including) inside the partition, the specific area of how much (depending on how much), a sheet of 1.22 * 2.44 = 2.97 square meters, estimated the need for fire board (with loss) Four, even the top cabinet came out (these are counted on the table). Door area of about 4 square meters, count down 1.36, the door needs to buy two, but also some of the rich plate. Above for reference, if any access please do not see strange.
Q:Plate furniture formaldehyde release national standard is
0.08 bar. Furniture, what is more or less taste, so the distribution of formaldehyde will be more, this is also normal. Select the time to try to choose the sample, the placement of a long time there is no, or you can buy more time to smell, if you have bought back, put it, conditionally with some herbs to break down formaldehyde, Is no secondary pollution, no harm.
