However, there are many aspects of knowledge that manufacturers still do not know clearly, so our factory is here to give you a brief introduction! 1. Eradicate the original wall surface, seal the base layer with interface enhancer, then use formaldehyde-free
Problems caused by irregular use of glass yarn
Although it is said that glass yarn can be glued in different ways using alkali-resistant emulsion or urea-formaldehyde glue no matter how many grams it is, for those in the industry, as long as they know the gram weight, not to mention the gluing method is basically fixed. The glue and weight of this product are the same at both ends and double-layered in the middle. The specific explanation is as follows: Taking
What special new features does glass yarn have?
Glass yarn is made of Fiber Glass tissue as the main raw material. After being soaked in polymer anti-emulsion coating, it has good alkali resistance and flexibility. It is currently widely used in thermal insulation, waterproofing, and waterproofing of interior and exterior walls of buildings. Anti-crack etc. glass yarn has some special properties, which are introduced below. 1. Glass yarn has relatively high node strength,
Properties that glass yarn that has good correlation with plastering glue should have
1.Higher node strength If the nodes slip when the glass yarn is stretched, the stress in the initial stage will be mostly borne by the plastering glue and cracks will occur. The test method for node strength is: cut a 330mm×50mm test strip along the weft direction, and cut off all the woven yarns on both sides about 150mm from the end of the test strip, leaving only one weft yarn in the middle; nodes), cut the weft yarn in the middle. Put the test strip on a tensile machine for a tensile test. One end of the testing machine clamps the weft yarn, and the other end clamps al
Glass yarn should be used to prevent cracking of external insulation system
1. Breaking strength and alkali resistance strength retention rate Breaking strength and alkali resistance strength retention rate are important properties of glass yarn. Breaking strength is inseparable from glass count or weight. At present, the glass yarn used for exterior wall insulation systems on the Chinese market generally weighs about 130g per square meter, and its strength is generally low. Its normal breaking strength is only about 1000N/5cm. In Europe or the United States, where exterior wall insulation technology and regulations are relatively mature, the requirements
Glass yarn plays a certain role in building insulation and anti-cracking projects
There are two types of glass yarn for exterior wall painting and plastering: one is glass yarn with a weight of more than 100 grams; the other is a glass yarn with a weight of less than 100 grams. Reasonable material selection and grid cloth specifications for painting construction should be carried out according to the requirements of the region and construction unit. Mostly 5*5, wire diameter between 0.4-0.9mm.
Glass yarn is the "soft steel bar" in the construction industry
In engineering construction, the most commonly used and obviously visible ones are steel bars and cement, which constitute the main body of the building. But today we are going to introduce to you a type of steel bar called "soft steel bar" in the insulation system. Engineering construction materials-glass yarn. Fiber Glass is made of glass fiber woven fabric as the base material, and is coated after being soaked i
The construction process sequence of wall treatment glass yarn is as follows
First, apply interface agent to the wall to be constructed, and paste kraft paper or Fiber Glass on cracks. Use an ink fountain to stretch the thread at the inner corner, and use plaster to find the straightness. The outer corner also needs to be vertical with a two-meter ruler hanging a hammer ball, and use plaster to find the straightness. The wall should be inspected with a two-meter ruler. High places can be shoveled down appropriately, and low places can be filled with plaster. After the yin and yang angles are straightened, the error is within 3 mm, and the wall surface is tested w
In the past, internal insulation technology for exterior walls was popular, and Fiber Glass insulation was in the experimental stage. In recent years, grid cloth insulation has increased, while internal insulation of exterior walls has decreased significantly. Some villas use exterior wall sandwich insulation technology. The materials are also diverse, including polystyrene foam board, silicate composite slurry, rock wool and slag wool, glass wool, foam glass, polyurethane foam board, etc.
What issues need to be paid attention to during the installation process of glass yarn?
The following points should be paid attention to during the production process of its mortar anti-crack Fiber Glass: 1. The glass yarn material must be put in in batches and cannot be put in all at once; 2. Precautions during the production process of mortar anti-crack Fiber Glass: When adding polypropylene fibers, they must be dispersed in cement first, because the fine particles of cement can eliminate the static
Glass yarn of three modes of exterior wall insulation system
Glass yarn exterior wall insulation technology is not only economical but also relatively simple to operate, but it also has some shortcomings: 1. The hot and cold bridges in the beam and column parts are not easy to deal with. 2. The required thickness of the insulation layer is relatively large, which will occupy the practical area of the building. 3. It will have some impact on the second decoratio
What performance indicators should be considered when choosing glass yarn?
1. Thermal conductivity: As a thermal insulation material, the thermal conductivity should be as small as possible. Generally, the thermal conductivity should be less than 0.14W/m*K. As a cold insulation material, the requirements for thermal conductivity are higher. 2. Bulk density: The bulk density of thermal insulation materials should generally be less than 600kg/m. Materials with small bulk density generally have
How to identify quality problems with glass yarn
1. The market price of the worst Fiber Glass is usually around 1.00 yuan to 1.60 yuan. Its Fiber Glass is usually made of some waste glass from beer bottles. The production process is clay crucible drawing, which is a production process prohibited by the state. The surface coating is also not an alkali-resistant emulsion. From an intuitive point of view: the workmanship is relatively rough, and generally sold in large quantities in the market. The length is often insufficient, the weight is insufficient, and it breaks after folding twice. The joints are not strong and easy to shift, and
Issues that should be paid attention to during transportation of glass yarn
During the transportation process of the Fiber Glass, first of all, we must pay attention to moisture and rain, prevent the glass yarn from being restored by moisture, and pay attention to weather changes; secondly, we must try to avoid heavy pressure on the glass yarn. Emulsion glass yarn is better, it is soft in nature, and is not afraid of squeezing. Pressure, but I can't do it at all with urine glue. It is relatively hard and brittle, and will deform and break under strong squeezing.
The use of glass yarn enhances the performance of buildings
Glass yarn is very popular in the new insulation material market. The E-shaped plate used on the outside of the glass yarn has a low thermal conductivity and can wrap the exterior wall as a whole, eliminating thermal bridges in the building and reducing air, wind and The infiltration of moisture reduces the thermal and cold impact of the outside world on the building. Whether it is hot summer or cold winter, the external insulation system is always effective and has superior performance than other insulation materials.
Briefly describe the corner protectors and their applications as supporting products for glass yarn
Glass yarn is a building material used to reinforce wall insulation structures, and it is inevitable that the corners of the wall will also need to be laid. This requires the use of another supporting material for glass yarn - PVC. Corner strips. PVC corner protection strips are made of PVC material and are divided into two types: external corner protection strips and internal corner protection strips, which are divi
How to make the glass yarn stick to the wall better?
1. A dedicated person must be responsible for preparing polymer mortar to ensure the mixing quality. Open the lid of the bucket by rotating it counterclockwise, and use a stirrer or other tools to re-stir the adhesive to avoid separation of the adhesive. Stir appropriately to avoid quality problems. 2. The mixing ratio of polymer mortar is: KL binder: 425# sulfoaluminate cement: sand (use 18 Fiber Glass sieve bottom): =1:1.88:3.
How to correctly use glass yarn in exterior wall insulation system
1. Under what circumstances may the surface layer crack ① When the density of the glass yarn is insufficient or the longitude and latitude lines are not straight, it will cause insufficient binding force during the expansion and contraction of the surface layer, and may even cause "breakage", which will not play the role of constraining the "ribs" and may easily cause the surface layer to crack; ② There are too few bu
