First, pour the glue on the flat glass to observe its rheology, and wiggle it to observe its rheology,If the flow of glue is too fast, it means that the glue is too thin and poor, and too thick is not conducive to bonding. Secondly, with a hand dip to observe its viscosity if you can slowly draw, a little sticky hand is better. Then, pour it on a small piece of glass to observe its film forming time if it is about 1 to 2 minutes, the film forming time of the glue can form a film on the glue surface is better. The fourth step, the glue after the film is basically solidified with fingers dipped in water to diarrhea, observe its cohesion if the glue is quickly changed to open cohesion is poor after diarrhea glue is turbidified - with filler Finally, stagger the two boards and glue them together. After 24 hours, measure the tension. Soak them for a day and then dry them in the sun to observe the color change Our company produces water based adhesive, welcome to consult

Surface treatment of metal materials 1)metal material surface degreasing: organic solvent degreasing alkali degreasing electric degreasing ultrasonic degreasing 2)metal material surface derusting 3)Activation treatment of metal surface 4)Metal surface sandblasting treatment: increase the surface roughness Surface treatment of non-metallic materials 1)Mechanical treatment: sandpaper grinding, etc 2)Physical treatment: electric field flame plasma treatment and other methods 3)Chemical treatment: acid strong oxidant, et 4)Radiation grafting treatment With the progress of The Times and society, people's requirements for automotive interior parts are constantly improving. In addition to internal decoration, they also need to take into account the requirements of functional safety, energy saving and environmental protection.In this regard, our research and development and innovation of automotive interior adhesive will follow the market orientation to meet customer needs Sinograce chemical produces all kinds of non-stick coating, and provides technical guidance, welcome to contact

Non-stick pot is cooking will not stick to the bottom of the pot, because the bottom of the pot uses a non-stick coating, the common non-stick can best have teflon coating and ceramic coating. The non-stick pan overcomes all the shortcomings of the traditional pot, easy to clean, a light wipe is clean, non-stick pan can easily fry food without sticking to the bottom, can minimize the oil, the kitchen is clean and less lampblack.It can also help reduce the intake of fat, following the modern trend of low fat and low calorie consumption. Non-stick products according to the use of different functions can be divided into boiling pot frying pot frying pot milk pot, according to the inner surface of the non-stick coating system can be divided into a layer of system two layer system and three layer system pot. A layer system refers to a non-stick layer composed of a single coating; The two-layer system refers to the non-stick layer composed of the bottom layer and the surface layer; The three-layer system refers to the non-stick layer composed of the bottom middle layer and the surface layer of 3 kinds of coating according to the product surface treatment method can be divided into enamel high temperature resistant paint polishing non-stick pan Sinograce chemical produces all kinds of non-stick coating, and provides technical guidance, welcome to contact

(1)The labels on the market (especially film labels) mostly use screen printing and flexographic printing, which not only has a complex processing process, a long cycle, but also has poor timeliness. (2)In terms of product design, the selection of design scheme needs to be modified repeatedly, which is not only troublesome, but also costly (3)The traditional printing method to achieve variable data printing digital coding bar code and other anti-counterfeit logo printing, need to be realized by two or even three times of printing, than digital printing cumbersome (4)The inability to handle short editions of less than 2,000 copies, such as labels or packaging for promotional or trial sale items, makes printing companies not only unprofitable, but also lose money (5)Customers have higher and higher requirements for print quality, print volume is getting smaller and smaller, making the market competitiveness of traditional label printing constantly decline We produce all kinds of printing inks, welcome to consult,this is our email sales@sinogracechem.com
