(3) Cleaning: At the end of the injection operation, injection holes, spills, and excess resins and putties on the crack surface should be removed from the visible surfaces of the work. This can be done by sanding, shaving, or high-pressure waterjet. Prepared mortars or other suitable repair materials should be anticipated and applied to fill […]
Epoxy resins have many unique applications in various industries, including building quality, due to their unique properties. These resins are used in the construction industry in fillers, coatings, flooring, repairers, polymer concretes, etc. Epoxy resin and Hardener are used in modern polymer concretes. Instead of using cement as an adhesive, epoxy resin flooring for homes […]
Polyurethane resins have a very short life after mixing, so mixing should be done when all components are ready and injection of special single-stage equipment such as that used for injection of epoxy resin in large repairs. Existing repair instructions do not allow the injection of 100% pure resin. A mixture of water and resin […]
Among the methods of repairing concrete structures is an injection of epoxy resin and polyurethane. Resin injection: Resin injection is used to repair only concrete with cracks or spots, joints, and wet cracks. Two main methods are used to improve concrete using the resin injection technique: A – Epoxy resin: Epoxy resins are solid treated with […]
Polyurethane and its derivatives are widely used polymers in various industries around the world. The formulation of these polymers is such that it covers a wide range of complex, dry, and compact materials. Polyurethanes are composed of an additive reaction between the isocyanate and hydroxyl functional groups. If a diamine reacts with isocyanate instead of […]
Differences between polyurethane flooring and epoxy flooring In general, polyurethane and epoxy flooring are the most widely used coating materials in Iran and even globally, but the differences between the two types of flooring have sometimes led to very different uses. As a general comparison between the properties of the two floors, it should be […]
Polyurethanes are a good example; these materials have many and varied applications in human life. Applications that are primarily for comfort and energy saving. Polyurethanes are also used for entertainment and fun. The unique properties of these materials have led to a great variety in the use of polyurethane resin floors . We cannot really […]
In general, reducing floor pollution and protecting surfaces from corrosion may lead to the provision of durable flooring that is resistant to harsh environmental and chemical conditions. On the other hand, issues related to the architecture and aesthetics of the environment are just as important. Polyurethane flooring system or polyurethane flooring is one of the […]
Polyurethane resin flooring is a type of polymer used for various purposes in the medical world due to its many benefits. This property of polyurethane has expanded its application in multiple sectors of life. Due to its hygienic form in the form of elastomers, this polymer has many applications in the manufacture of tank covers, […]
Polyurethane dispersion resins (PUDs) A well-known approach within the manufacture of water-primarily based polyurethane dispersion resins is getting ready a prepolymer with the very last isocyanate institution, which modifies the polyol withinside the chain shape carboxylic acid purposeful institution. This fabric with the 0.33 form of amine in Water is dispersed to shape ionic centres […]
