Waterproof and breathable membrane production process update

The gas permeability of the Kedebang waterproof and breathable membrane is more than 1500g/m2/24h.
Waterproof and breathable membrane production process:

There are three main types:

1. Casting compounding. This process uses plastic particles to add a permeable functional masterbatch after the hot melt relies on the viscous compounding of the plastic itself. The disadvantage is that the air permeability is relatively low, but the waterproof performance is very good. The waterproof and breathable membrane of the composite process is generally used in walls or relatively dry areas.

2. Glue or scrape compound (hot melt adhesive compound). This process was first applied to sanitary napkins and diapers, as well as protective clothing. At present, domestic manufacturers almost always use this process to produce highly breathable waterproof and breathable materials. The disadvantage is that the hot melt adhesive blocks a part of the micropores, thereby destroying the air permeability of the product. The waterproof gas permeable membrane has a gas permeability of between 1000 g/m2/24h and 1500g/m2/24h.

3. Hot pressing compounding. At present, the domestic market is mixed, and the manufacturers of genuine waterproof and breathable membranes are actually few. Because this product market is relatively narrow and the equipment is professional, it is difficult to recover the equipment investment cost without a certain amount of output and sales volume, let alone update the production process of the products. Many factories or distributors say that their waterproof and breathable membranes are good. In fact, the real waterproof and breathable membranes should be highly breathable, high temperature resistant and anti-aging. The production process should be pure thermal composite technology, without glue, so it can reach temperature resistance above 100 degrees, high strength and anti-aging, gas permeability over 1500g/m2/24h, stable at around 2300g/m2/24h. This is the current product that can truly meet EU standards. The waterproof and breathable membrane produced by Nantong Kangda Composite Materials Co., Ltd. (Jiangsu Kedebao Building Energy-saving Technology Co., Ltd.) adopts the latest technology to overcome the shortcomings of most manufacturers in the past, using glue-free water production, so the surface is flat, can not afford Wrinkle foaming, good composite fastness, high strength and air permeability, anti-aging and high temperature resistance. At present, it has a very wide market in European countries and is an indispensable product in the construction industry in these regions. Currently mainly exported to the United Kingdom, Poland, Finland, Sweden, Norway, Italy, Greece, Cyprus, Ukraine, the Netherlands, Latvia, Southeast Asia, Australia, New Zealand and other countries and regions.

In detergents, detergents are mainly surfactants and are mixed with certain adjuvants. The addition of adjuvant not only reduces the cost of finished detergent, but also improves the detergent decontamination ability, improves the appearance of detergent, and makes the detergent more convenient for use. In addition, a small amount of functional auxiliary ingredients (additives) are usually added to improve the comprehensive properties of washing.

Auxiliaries refer to the auxiliary components in synthetic detergents, which are related to decontamination and can increase washing characteristics. Most of the auxiliaries are inorganic, mainly Phosphate, 4A zeolite, silicate and Carbonate. In addition, organic chelating agents also belong to the category of auxiliaries.

Auxiliaries can be divided into inorganic auxiliaries, according to their functions in detergents, they can be divided into mixtures, foaming agents, defoamers, thickening (viscosity) agents, solvents, pearlescent agents, preservatives, bleaching agents, bactericides (disinfectants), antioxidants, softeners, antistatic agents, friction agents, fluorescent brighteners (FWA), solvents, anti-fouling and re-deposition. Agents, enzymes, flavors, pigments, etc.
