With the concept of green environmental protection deeply rooted, more and more people will pay attention to their environmental performance when choosing furniture and building materials. We all know that after the renovation of the new house, the interior has more or less harmful gases. These gases may contain formaldehyde, benzene, ammonia, hydrazine and other components. The source of these gases is mainly the renovation of building materials and furniture. The glue is very One of the important sources! So, there is formaldehyde in the decoration glue ? We now have a look at all kinds of decoration glue formaldehyde !
1, white latex
White latex, room temperature curing, with water as dispersant, is a water-soluble adhesive whose main component is polyvinyl acetate. White latex is often used to paste wallpaper and wood, but also as a waterproof coating adhesive. Under normal circumstances, qualified big brand products are green, healthy and non-toxic. However, due to the proliferation of fake and shoddy products in the market, some inferior products often use formaldehyde as a preservative, which greatly jeopardizes human health. Want to distinguish high-quality white latex, in addition to inspection certificates, you can see whether the appearance of the layer, whether precipitation, smell whether there is a pungent odor!
2, glass glue
This is also a common adhesive, mainly used to paste glass, ceramics, aluminum alloys and other building materials. The main components of glass glue are sodium silicate, acetic acid and silicone. The gap between our toilet and the floor is often sealed with glass glue. Glass glue is divided into acidic and neutral, neutral glass glue is non-corrosive, acidic glass glue is corrosive, and there is an odor to stimulate the eyes and respiratory tract after use. It is slightly toxic and often requires window ventilation after use.
It is important to note that inferior styrofoam can cause heavy odors, and certain harmful gases can be emitted during the curing process; besides, in terms of service life, inferior glass adhesives will differ from high-quality adhesives by more than 10 times. When, try to buy in the regular brand manufacturers!
3, all-purpose adhesive
In life, we often use all-purpose adhesives, which do not necessarily need to be used during decoration. Adhesives are used in a wide range of applications and can be used for the bonding of various materials such as wood, metal, ceramics, and plastics. The adhesive belongs to the solvent type glue and its main components are solvent, film and resin. Among them, the solvent is the most prone source of harmful substances. Many inferior multi-purpose adhesives use low-cost, high-toxicity solvents, leading to great harm to the adhesive!
When choosing the adhesive, you can choose the brand's environment-friendly universal adhesive. This kind of glue does not contain triphenyls and also has substances. The glue is clear and can be used with confidence!
4, marble adhesive
Marble glue is mainly used for sticking materials such as tiles and stone, and has good repairing, bonding and caulking effects. Its raw materials can be divided into two kinds of epoxy resin and unsaturated resin. High quality marble glue may contain a small amount of formaldehyde and other substances, but it must be within the environmental standards. However, some inferior adhesives contain aromatic hydrocarbons, which release harmful gases such as toluene. Therefore, when purchasing, remember to choose environmentally-friendly products!
It is also worth noting that marble adhesives should not be used in excessively humid environments and they are easily sticky. In addition, the marble resin with unsaturated resin can also work in a humid environment! After using marble glue, remember to open the window and ventilate, keep the air circulation, which will help dry!
About the decoration glue there is formaldehyde related content, Xiaobian introduced to everyone here, and hope to all of you help! In fact, now some of the big brands of glue will focus on the environmental protection of the product. When you choose, pay attention to the product's safety certificate!

Expanded wire mesh is a variety in the metal screen industry. Also known as metal mesh, Diamond Mesh, iron mesh, metal expanded mesh, heavy steel mesh, foot mesh, punched aluminum sheet mesh, stainless steel mesh, granary mesh, antenna mesh, filter mesh, audio mesh, etc.
specification
Short Pitch (SWM): The length of a short rhombus diagonal from the center of the node to the center of the node.
Long Pitch (LWM): The length of the long rhombic diagonal from the center of the node to the center of the node.
Short pitch (inner hole) (SWD): the length of the diagonal of the short rhombus hole (as shown)
Long Pitch (Inner Hole) (LWD): The length of the diagonal of the long diamond hole. (Pictured)
Strand: The edge of the diamond mesh hole of the expanded metal (as shown in the figure). The width of the stem is the length of the metal plate used to make a wire stem.
Bond: The junction of two silk stalks.
Thickness: The thickness of the original steel sheet.
Roll: A rolled wire mesh that indicates a specific length and width.
Mesh: A steel mesh that indicates a specific length and width
Weaving and characteristics
It is made of steel sheet through stamping and stretching; it is divided into expanded metal mesh and stainless steel expanded metal mesh; beautiful and elegant, durable.
Surface treatment
PVC dip (plastic spray, plastic coated), hot-dip galvanized, electro-galvanized, anodized (aluminum sheet), spray anti-rust paint, etc
Anti-rust method
First, add some rare elements in ordinary steel to change the internal structure of the metal.
Second, cover the metal surface with a protective layer to isolate the surrounding corrosive medium, thereby preventing the anti-corrosion effect. For example: the surface of the expanded metal is coated with oil, vaseline, paint or covered with non-corrosive non-metallic materials such as enamel, pvc, etc .; the surface of the expanded steel is plated with zinc, chromium, nickel, etc. ; Use chemical methods to form a fine and stable oxide film on the surface of steel. For example, a thin black iron oxide film is formed on the surface of steel parts such as machine parts and guns.
Third, often wipe metal equipment or place desiccants in precision instruments and add a small amount of corrosion inhibitors that can slow down the corrosion rate in corrosive media.
