In the south, there is lots of rainning day in summer, so it is necessary to do waterproofing for   building formwork , since they are made of hot-pressed glue. With the increase of the number of turnovers and the cross-section is eroded by water immersion, building formwork is becoming no longer waterproof. Apply oil on the surface of building formwork after it removed. In the north, due to high temperature, dryness and strong wind weather in summer, it cause many defects for concrete, especially dry cracking. Therefore, the concrete pouring on the construction site should avoid the high temperature period, and pay much attention on maintenance of the concrete in hot weather. ZMADTO Plywood Co.Ltd.  is professional manufacture in plywood. We supplier all kind of film faced plywood, particle board, MDF board in all kinds and size, if you have any require, welcome to call us.

1. Raw Material The cost of raw materials will affect the price of the plywood formwork used on the construction site. For example, for a 42 yuan construction plywood formwork, if the original board core or adhesive is replaced by cheap materials, the cost of the manufacturer can be reduced by 2 yuan. 2. Thickness and Size The thickness is between 1.2cm and 1.8cm, and some small manufacturers will deliberately describe the difference between the specification and actual thickness of the plywood formwork as a manufacturing error. How much does it cost to buy a piece of plywood? Taking 1.4cm plywood as an example, the market price is 42 yuan/piece, so if the manufacturer makes it 1.3cm thick, the price becomes 37 yuan/piece. 3. Turnover Large manufacturers can ensure that their plywood can be used a certain number of times. For example, the 8 layers of some plywoods have been used more than 10 times, and a few small manufacturers can only use 5-6 times.  The above are the factors tha...

The full name of   OSB   is oriented strand board, it is source to the scientific name of "Osong board", which is a new type of board from Europe and developed rapidly in international market in the 1970s and 1980s. Its production process is similar to   particle board . Both of them are made of stone glue pressed to board after crushing and slicing wood. The difference of them are on the size of the sheet and the layer of paving. The thin slices of particle board are small, and it has 1mm balance layer in the middle. There are three layers in total, while OSB is five layers. OSB board is taking small-diameter timber, thinning timber and wood core as raw materials, and is processed into long shavings (usually 40-100mm long, 5-20 mm wide, 0.3-0.7 mm thick). ZMADTO Plywood Co.Ltd.  is professional manufacture in plywood. We supplier all kind of film faced plywood, particle board, MDF board in all kinds and size, if you have any require, welcome to call us.

  Plywood is a construction wood sheet made up of thin layers of wood veneers glued together placing wood grains 90 degrees to one another.  That leads to a solid board or piece of plywood that can be used for a wide array of applications. Below are the pros and cons of Plywood:   Advantages: 1.  Plywood  features durability and high strength. It is large-scale used in engineering and civil projects because of the use of many layers of wood veneer. 2. Due to the way in which plywood is made, you can customize the thickness that you want ranging from 6mm to 32mm. 3. It is easy to cut in shapes and can be bent. Plywood is flexible and it can be bent and cut into various shapes. 4. It is relatively lightweight and inexpensive. 5. It is convenient to use any polish and paint on plywood with no worries.   Disadvantages: 1. It is not durable like wood. 2. It is hard to saw for its materials and structure. 3. Compared with wood, plywood may release volatile organi...

How to effectively remove the oil stain on the surface of the   building formwork ? Building formwork may have oil stains on it during the use and storage, which will affect its performance and service life. Therefore, the oil stain on the surface of the building formwork should be removed in time. Next, let's learn how to remove oil stains: 1. Degreasing with organic solvent. Using xylene and other solutions to clear the template of oil stains. It can remove oil stains well, but organic solvents are easy to burn and pollute the environment, which can not be widely used. 2. Degrease with lye. The saponified vegetable oil, animal oil and alkali are reacted to produce water-soluble glycerin and soap. Glycerin is dissolved in water, after it flows out with water, the soap can further emulsify the oil and generate the emulsification of water and oil to achieve the purpose of oil removal, so this method is very effective. ZMADTO Plywood Co.Ltd.  is professional manufacture in plywo...

Deformation often happened on   construction formwork , so we must to pay attention to do maintenance to prevent formwork deformation during usage. Preventing construction formwork deformation is mainly in the following five points. 1. After the wooden formwork is installed and passed the strict inspection, should pour concrete in time to prevent the building formwork from being exposed to the sun or rain for a long time to absorb water and deform. 2. The beam bottom support distance between each point ensures that the load effect is not affected by the span impact and deformation. On the ground support bottom, a stable and hard object should be placed to ensure that the support point does not sag, and pay attention to waterproofing. 3. In the construction planning of the formwork and support system, the self-weight, load and additional pressure and impact force of the concrete should be considered to ensure that the construction support of the formwork can meet the bearing capacit...

Plywood formwork is a relatively low-cost, lightweight, flexible, warping and cracking resistance building material that provides a high-quality concrete cast surface. What materials are used to produce plywood? 1. The foundation plywood is made of pine wood, poplar wood, and eucalyptus wood. The thickness of the side plate of the floor beam is 20mm. a. Pine is better for ordinary plywood because it is not easy to deformation with high strength. b. Poplar is basically used for  film-faced plywood , which is widely applied in projects with high requirements. c.  Eucalyptus is a little more brittle. Plywood formwork of all eucalyptus is relatively few, and its weight is heavier than pine. 2, The main beam, bottom plywood and floor plywood use 9 Feet Plywood Board, with a thickness of 12mm. 3. The supporting system is made of fir logs with a small head diameter of no less than 70mm, and the bottom supporting system is supported by steel pipes. 4, Plywood and support system shall ...
