Hello\r\nIs the fuel class of your truck capacity (like some of your colleagues across the country) on the diesel fuel card lower than the capacity on the official vehicle ownership document issued by the traffic police?\r\nDue to various reasons, the main tonnage (capacity) of the truck, which is included in the official road document, is inconsistent with what is issued in the diesel fuel card, and the correction of this discrepancy requires follow-up and referral to different offices in Tehran.\r\nWe are in Tehran to solve your problem.\r\ncontact us.\r\nGood luck\r\nHamidreza Khaknejad

Polyurethane insulation (cold insulation) is one of the best materials in the world and the cold insulation industry in various industries. It has a very low heat transfer coefficient and the ability to maintain heat and cold from +120 to -200 Polyurethane is produced from the reaction of hydroxyl (polyol), isocyanate, permitted gases, permitted additives of fire retardant materials. Polyurethane spray foam is the most common type of spray foam. Insulation was created in the 1940s.\r\nIt was used in the military for airplanes.\r\nIt was used as insulation in buildings in the 1970s.\r\n\r\nThe most common type of poly insulation. Urethane is a spray insulation, this foam is a type of building insulation that is used in walls, ceilings, seams, open pores and other parts of the building, as well as to maintain heat in winter and cold in summer. In its closed cell type, it can be called He used it for sound and moisture insulation and thermal insulation.\r\n\r\nThis insulation consists of polyurethane foam and isocyanate (glue), which are combined together during spraying and form insulation foam.\r\ n\r\nCharacteristics and characteristics of polyurethane insulation\r\nThe following are the characteristics and characteristics of polyurethane insulation:\r\nIt has a low heat transfer coefficient\r\nResistant to erosion and corrosion\r\nResistant in Against moisture, acid and solvents\r\nPrevention of water penetration\r\nNo release of gas and harmful substances\r\nCan be used in a wide range of temperatures\r\nAnti-bacterial and banana-animals and resistant to microbial, fungal and Biological\r\nExcellent and stable thermal performance\r\nLow weight polyurethane insulation\r\nResistant to sudden temperature changes\r\nAbility to change density (from 30 to 1000 kg/m3)\r\nVery suitable for Industrial\r\nWhat are the types of polyurethane insulation?\r\n\r\nThe following types of polyurethane insulation can be mentioned:\r\n\r\nPolyurethane insulation in block and board form\r\nPolyurethane insulation Urethane as prefabricated pipe\r\nPolyurethane insulation as injection\r\nPolyurethane insulation as spray\r\nTypes of hot and cold mastics

Production of mastic and polyurethane adhesive 81-84, adhesive and sealant 30-45, sealant to cover vapor barrer 90-60 and mastic 95-44 in the form of cartridges on the surface of polyurethane insulation and insulation, pipelines and equipment with PM and pip brands and seam adhesives Silicone and polyurethane sausage band for concrete joints and.....\r\nProduction of mastic, glue and epoxy for use in wood, ceramics, tiles and insulation of marine piers and uPVC windows and...\r\nProduction of emulsion resins and water-based mastic and solvent and tile adhesive paste, flooring, swimming pool, cement, concrete, and glass glue\r\nNowadays, polyurethane mastic or polyurethane glue is very widely used in construction and industry. These adhesives are often favored by experts due to their special properties. Among the properties of polyurethane, we can mention things such as high mechanical resistance, high adhesion properties on most surfaces. The main application of glue or polyurethane sealant can be mentioned for sealing inside concrete, such as sealing June seam or expansion seam. Regarding the disadvantages of polyurethane, we can mention low strength on glass, low resistance to sunlight. Chasbiar Group is one of the most trusted sources of polyurethane glue.\r\nThe most important reason or feature that causes polyurethane mastic to be widely used is its proper elasticity and at the same time its adhesive strength on different surfaces. Polyurethane mastic has good resistance to impact and vibrations. In addition, the mechanical resistance of this glue is much higher compared to silicone.
