Water-based adhesive with high polymer, water-soluble resin as the main raw materials, water as the solvent, odor is small, environmental protection and non-toxic. With the continuous improvement of people's environmental awareness, water-based adhesives have become the mainstream of the market in recent years. In practical application, some packaging and printing manufacturers do not know enough about water-based adhesives, which causes some quality problems. Among them, the water-based adhesive "difficult to bond" problem is one of the technical bottlenecks plaguing many packaging printing enterprises.In order to let more packaging and printing enterprises understand water-based adhesive, the following will be elaborated from the characteristics and selection of water-based adhesive two aspects, I hope to help you. Characteristics of water-based adhesive Any kind of adhesive for substrate is not omnipotent, an adhesive is only suitable for bonding some or some kind of specific material. Such as Lamination Adhesive SA-2800X and Water Based Dry Laminating Adhesive SA-228 series water-based adhesives are mainly used for bonding between paper/paper, PET film/paper, BOPP film/paper, wood/paper and other substrates. Every kind of water-based adhesive has its "inherent characteristics". The inherent characteristics of water-based adhesive mainly include appearance (product appearance and film appearance), solid content, density, pH value, solvent ratio, opening time, high and low temperature resistance, initial viscosity, curing viscosity, etc. The bonding mode of water-based adhesive is generally divided into three kinds: machine adhesive, hand adhesive, machine adhesive and hand adhesive. Different bonding modes correspond to different inherent characteristics. For example, when using machine adhesive, water-based adhesive opening time is required to be short; When using hand adhesive, the water-based adhesive is required to open for a long time; When the film surface bonding, the adhesive film is flexible and the curing viscosity is high. For the analysis of the characteristics of water-based packaging adhesive, please see the next article.

I.Overview: Refilm process is widely used in all kinds of packaging, small to medicine box, artifact box, large to outer packing boxes and various product packaging.The current recoating technology includes precoating, dry recoating and wet recoating.Wet composite uses water-soluble adhesive cold paste process. Dry composite traditional composite film process is to apply solvent-based adhesive directly to BOPP film, and after drying in the drying channel, press with printed matter under heating and pressure. Due to the use of flammable and toxic solvents, it brings great harm to workers and the environment. And it's a fire hazard. The process generally adopts SBS one-component adhesive and polyurethane two-component adhesive.At present, due to the price rise of solvents and related raw materials, resulting in increased production and use costs, basically unprofitable. Water-based hot recompound is also called water-based dry compound adhesive, dry laminating adhesive, dry laminating adhesive, dry laminating adhesive and so on.Special use of traditional  Dry laminating machine or water-based dry reproducing machine, dry reproducing machine, instead of Solvent-based laminating adhesive, suitable for BOPP, PET film and a variety of color printing paper high speed bonding.

1. the reason why non-stick pot is not stick, all rely on the coating material on the surface of the pot. These coating materials have good lubricity, small friction coefficient, small surface tension, food is not easy to stick to the pot.Two types of coating materials are commonly used for nonstick pans: fluoropolymers, such as teflon, and silicone polymers. Non-stick wok use PFOA-free high quality non-stick coating, safe and non-toxic; 2.The upper limit of the safe use of non-stick pot temperature is 260℃, beyond this temperature, non-stick coating may decompose and produce some toxic gases, and the general smoke temperature of cooking oil is about 200℃, less than the safety limit, so it is relatively safe; 3.non-stick pot good thermal conductivity, the use of small and medium fire can achieve the best cooking effect. At present, our company's non stick coating and water based ptfe coating and Ceramic Series coating, has been put on the market, the market feedback is good, the performance is excellent, fully able to meet the complex needs of customers of various packaging structures. Description Water based Three-layer Marble-Coating (Starry Sky)PF-612 is Water based Two-layer Marble-Coating (Starry Sky).

Type Water based marble-coating Key features -Eco-friendly and PFOA free -Showing the effect of natural marble -Excellent chemical resistance and abrasive resistance -Excellent and lasting non-stick performance, easy to clean Our company produces a safer pfte nonstick coating for use on nonstick pans,Welcome to consult

"Non-stick pan" is a very common pot in the kitchen, because in the process of using less oil consumption, less smoke, but also not easy to paste the problem, so it is welcomed by many people. In recent years, however, there have been more and more controversies about non-stick pans: Some people think that non-stick coating will produce toxic substances, can not be used for a long time; Some people feel that the use of non-stick pan is very convenient, and use for so long, also did not find the body appears any discomfort symptoms. So is nonstick coating really toxic? Can the nonstick pan at home still be used? Today we'll have a look too. The reason why the non-stick pan is not stick The non-stick pan we use is able to do non-stick, the main reason is the coating material on the surface of the pan. The surface of non-stick pot will use a special coating, this coating has good lubrication performance, and the coefficient of friction is very small, the surface tension is very small, so as to ensure that the non-stick pot in the process of use will not easily adhere to the substance, so it can achieve the effect of non-stick. The reason why we are willing to choose to use a non-stick pan is because of the characteristics of non-stick. It is not easy to paste the pan when frying dishes. Even when frying steak or eggs, it is also very convenient to put a little oil and not to stick to the pan. Is the coating of nonstick pans really toxic? As we all know, the most important thing about nonstick wok is the coating material used on its surface, but at the same time, the coating material is also the controversy of nonstick wok. Some people think that the coating used on the surface of non-stick pans will produce harmful substances. If these usually enter the food, it may even lead to poisoning and other symptoms, which will pose a great threat to our health. So what is the material of the coating of the nonstick pan? Teflon is the main substance of the coating material used in nonstick pans. The Teflon material does break down a little bit with the temperature, and the products that do break down, they have some toxicity. So is the coating of nonstick pans really bad for us? You don't have to worry too much about this. Although the Teflon coating in the nonstick pan will decompose, but the harm to the human body is very small, under normal circumstances, you can rest assured to use the nonstick pan. The Teflon in the nonstick coating doesn't start to break down until the temperature reaches 300 degrees Celsius. Experiments have shown that when the temperature reaches the decomposition temperature of Teflon, the decomposition will be carried out, but due to different temperature changes, the decomposed products will be different and the final toxicity will be different. In our normal cooking process, the temperature inside the nonstick pan rarely reaches 300 degrees Celsius, which means it does not reach the temperature of Teflon decomposition, and does n...
