هاردنرهای مورد مصرف در صنعت کفپوش عمدتا به دو گروه عمده اصلی زیر تقسیم میشوند
هاردنرهای پلی آمید : این گروه از هاردنرها عمدتا در رنگهای اپوکسی و پرایمر کاربرد داشته و بدلایل خصوصیات مناسب زیر استفاده گسترده ای دارند : انعطاف پذیرند مقاومت بالا نسبت به ضربه و مواد شیمیایی دارند و بدلیل چسبندگی بالا به بتن و مقتاومت مناسب به رطوبت در صنعت کفپوش عمدتا بعنوان هاردنر پرایمر مورد استفاده قرار میگیرد .
هاردنرهای پلی آمین
IHهاردنر پلی آمین این هاردنرها بسیار در صنعت و بخصوص صنعت کفپوش کاربرد داشته و برای روکش و لایه های کفپوش استفاده میشود این هاردنر بامقاومت شیمیایی نسبتا خوب معمولا در لایه ها و روکش استفاده میشودو رزین پس از خشک شدن بسیار سخت گردیده ودر دمای اتاق خشک میگردد
These diluents participate in the reaction and form part of the non-volatile binder. These diluents are non-volatile and do not evaporate. These low-viscosity liquids, when mixed with the original resin, reduce the final viscosity. In addition, the diluents improve the resin flexibility and the air bubbles formed leave the reaction faster.
Inactive epoxy thinners
These diluents do not react and are volatile and usually have high evaporation. These solvents reduce viscosity and cause problems such as reduced final strength after drying, risk of fire, evaporation and risk of poisoning by it.
Zinc Reach coatings are paints that have large amounts of zinc particles in their formulation along with resin and other additives to protect steel or other metals that are in very hard and permanent corrosion conditions. Zinc metal powder in these coatings is sacrificed. In these environments, it prevents corrosion and decay of the main metal and gives it electrochemical or cathodic protection.
Zinc Rich epoxy coating is two-component as a primer and primer is applied on the metal in the first layer and is very suitable for protecting the metal in marine and wet environments.
Barite is the most common barium mineral in nature and is an important additive in many industries, especially in the paint industry as a filler. This mineral has a specific gravity of more than 4 and its powder color is from white to gray.
Barite is widely used in the oil and gas drilling industry due to its neutrality, reasonable price, high specific gravity. The great advantage of barite in the paint industry is that it has no pigment effect and is used for uniform distribution of colored particles. And usually comes in 20 kg bags.
Hardeners used in the flooring industry are mainly divided into the following two main groups
Polyamide hardeners: This group of hardeners are mainly used in epoxy and primer paints and are widely used due to the following suitable properties: They are flexible, have high resistance to impact and chemicals, and due to their high adhesion to concrete and good moisture resistance in industry. Flooring is mainly used as a hardener primer.
IH Polyamine hardener These hardeners are widely used in industry, especially in the flooring industry, and are used for floor coverings and layers. This hardener with relatively good chemical resistance is usually used in layers and veneers. The resin hardens after drying and dries at room temperature.
The first step is to clean the polyurethane flooring, which is done in different ways according to its dirty condition, after which the floor should be sanded for more cleanness and creating suitable scratches. After completing these two steps, the primer coating should be applied on the floor. In this step, the diluted polyurethane liquid with high permeability should be poured on the floor. Creating a surface with high adhesion will protect the next layer from the separation of the floor in the future.
Therefore, the life and durability of the flooring directly depends on the quality of the primer, and choosing the right type of primer and the dryness and cleanliness of the surface when doing it is very important. One of the most important issues that should be considered before applying the primer is the complete dryness of the surface and not paying attention to it will cause a lot of damage.
It is one of the products of Farapooyesh which is produced on the basis of epoxy bisphenol A and hardener polyamine resin. Suitable and high quality and features as follows have many customers and is one of the main products of the company.
Excellent rolling property that creates smooth, undulating surfaces.It does not bubble due to having quality anti-bubble material.Due to the lack of inactive solvents, its strength and scratch-resistant properties are excellent.They do not catch fish due to high quality materials and advanced formulation.Its surface is not distorted due to its quality materials and proper formulation.It can be supplied in various colors according to the order.Can be ordered in relatively small quantities.It is very hard and does not get scratches easily.
The most important hardener used in polyurethanes is hardener
After the reaction of hardener and resin, which is an exothermic reaction and does not require heat to continue, and the result of this reaction is a stable material that is used in many industries such as flooring and protective coatings for pipes and metal structures and many others.
