A relatively recent development in the production of materials for the building industry is the use of wood particles and cement. There is also the production of chipboard combined with This provides great rigidity and high fire resistance A chip board having both of these features can be obtained. However, such chip board There are some practical drawbacks. This material is hygroscopic and contains 30% of its weight in water. can be absorbed. The natural balance water content is 9%, and if the water content decreases below this, the water will become stronger. degree loss occurs.

Designers calculating the weight of a structure that includes this board have a very large safety margin. It is necessary to provide some margin. The cement content is alkaline, which makes it difficult to harden with acid. The action is effectively stopped. Conventional paints can have high moisture content during application, causing Fluctuations in moisture can cause blistering. With an acid catalyst on a board like this Even if you simply apply a hardening phenolic resin, the effectiveness of the acid catalyst will affect the alkaline support. The above-mentioned difficulty is not alleviated because the data is lost even more.

Additionally, when manufacturing cement fiber boards, cement fines migrate to the surface. , the resulting finishing material may not be usable depending on the situation. A place like this In this case, the surface of the board is usually machined, which is expensive.

The board was then passed through calender rolls to consolidate the formulation. at the time The board, with the underside and two edges coated, is exposed to air at a temperature of 80°C. It was sent out through a tunnel oven with water flowing through it. In this state, water will separate The resin formulation is cured. Next, flip the board over, rotate it to 90 degrees, and again It was pumped through the system to coat the top surface and the remaining two edges. In this case, Stop spraying the powder and use the powder applicator head to coat the abrasion-resistant walking surface. Finished with makeup coloring. The powder used has a melting temperature of 4, which helps in fire safety tests. 00℃ colored glass frit, carporundum powder, fiber or coarse particles Alternatively, silica sand was also used.

Manufacture of fully encapsulated platform floor tiles with intricate and fine edges described At appropriate points during the process, the components are pressed in heated molds to fully cure the components. It was possible to do this by

The formulation was applied to the top and pressure was applied with a series of nip rollers. the above When the sandwich structure was tested at 1100℃ for 4 hours, no damage occurred. It was. This sandwich structure can be cut, drilled and screwed. Example 4 A cement-filled coating formulation was prepared according to the following formulation.

Alkaline phenol resin 50 parts by weight Butyllactone 10 parts by weight Cement 35 parts by weight Metal oxide colorant 5 parts by weight The water in the resin system hardens the cement, and the resin increases its strength. This formulation is applied inside the mold and transferred through the concrete pouring process. (transferred), a pre-finished casting can be formed.

Potassic resin, water, and catalyst were added. The mixture was placed on a stand mounted on a shaking table. Pour into a stainless steel flat tray.

After mixing and pouring, a portion of the mixture was cured, and the board could be removed from the mold within 7 seconds. warmth The cement was allowed to harden indoors for several hours to complete the production of the insulation board.

The surface of the board that used to be the mold surface has a good finish and can be painted with paint. It turned out that.

It also uses alkaline phenolic resin during the manufacture of cement-bonded chips and fiberboard. Adding esters to the formulation shortens curing time and reduces moisture absorption of the board. It was found that a small effect could be obtained.

In further experiments, two sheets of cement made by Pyrok The bonded wood fiber boards were placed vertically on the long edges and parallel to each other. board The gap between them is 40mm, and the size of the board is 10mm (thickness) x 2m.

Moisture generated, including that present in the resin, is removed from the cement and wax as part of the curing process. Absorbed by Lutracarb. Ultra Carb is a hydrated magnesium carbonate cal. It is the trade name of Cium. If the water and CO2 required are at the lower end of the temperature scale, Alumina trihydrate may be used in place of Ultracarb if released. . The mixture of alumina trihydrate and Ultracarb has more gas at the lower end temperature. This is followed by five further stages of gas production up to approximately ]000°C.

In Example 15, Cyment Fondue and Boatland Cement are - together. Cures extremely quickly, with resin/catalyst curing adjustable from 30 seconds to 30 minutes. Room-temperature molded products or coating materials can be produced. If the reaction time is too fast, Molasses can be added dissolved in a small amount of water to slow down the reaction rate (Example 16). However, appropriate ester catalyst selection is sufficient.

The formulations of Examples 13-1G may be used as binders for thermal materials. . In this case, Poraver (expanded) of various sizes is used as aggregate. 20-25 resin/powder to 80-8596 aggregate Good filling can be achieved at a ratio of 96%. Another suitable aggregate is Leka, which has different sizes. Expanded clay such as ca) or expanded kaolin clay in the form of granules ((prill) It is. The formulations that performed well in the index tests were composed of two sheets of 1011101 containing cement. British Standard 476 (BS476) part 8 (part 8) 8) gave a result of 4 hours for 40 carp thickness. This applies to both Reka and Polabar. It is a combination of both. Room-temperature molding porurusion can also produce paint.

The resin is alkaline (or neutral but has alkaline fillers) , meaning that it can be foamed by mechanical means. This operation 10 parts of cleaning agent such as Ally Liquid (Fajry Ljqujd) from 2 formulations Add to 100 parts of water coming out. Stir this mixture vigorously until all the water is absorbed. Taku. If using a molasses and water mixture, add it after this. after that, Mix resin thoroughly and add all powders. Ratioff10. 7 is obtained, and this This is maintained even when aggregate is mixed in.

The aggregates are Reka, expanded fireclay chamotte, kaolin grains (prill), and hill. Expanded foamed clay such as stone may also be used. All have a foamed or expanded structure and are It weighs less than water.

By adding a catalyst to this, aggregates with different sizes and compositions are created. Can be used to join together.

The resin is filled with powder particles of different sizes, so it does not shrink or crack. The chemical reaction absorbs excess water. One of the aggregates that can be used advantageously One is expanded vermiculite. Strong fire resistance using this combination of materials A sex board can be manufactured. Aggregate-free phenolic resin and powder components have good It provides a good adhesive for bonding many decorative boards onto lightweight aggregate-filled fire panels.

The board is made of calcium carbonate, Mineral fibers or vermiculite are placed in molds using phenolic resins and resin formulations. by pouring in layers with a concrete applicator or by spraying. It may be manufactured by joining them in a do-shape.

3. Next, apply a lightweight core material (26) consisting of phenolic resin powder and aggregate; Upper board (28) same as board (24) and metallization (22) (if required) Add and complete the process.

4. Remove air to keep the laminate stable and for the catalyst to work. , light pressure and vibration is sufficient.

The resulting board, especially the hillstone/fire sand inch construction, has a strong, lightweight, fast-heating layer. 4 hours or more without compromising integrity or insulation. can withstand flame for longer periods of time.

Example 20 A heat insulating agent was manufactured as follows.

In a mixing vessel, 200 g of water and liquid detergent Log were mixed. of phenolic resin Add alkaline phenol resin 600 [( were mixed and placed in a mixing container. Also, 200g of cement, 5° ultra curve A premix consisting of Og, 200 g of mica, 0 g of Sheepleaf and 20 g of Polklay. The composite powder was mixed. Next, Borabar (0゜5~Ill1m, 1~2m+n and 2-4[Il[[l is equivalent volume, 2-4[Il[n is 100g] Premix consisting of 500g and 800g of Reka (31 DOI ~ I Omm) After adding the aggregate, it was mixed with 80 g of ester catalyst.

The resulting mixture was poured into a mold and cured (5 minutes WR).
