Water-based plastic composite ink is a product with water as the solvent. From the perspective of printing mode, water-based ink is not suitable for offset printing at present. Its main application fields are flexographic printing gravure printing and screen printing. Printing costs are related to the raw materials selected by ink manufacturers, such as the size of the molecular weight of the resi...
From the development of printing industry in developed areas of the future development track can be considered in China's packaging and printing industry to take the road of environmental protection is an inevitable trend, and the environmental protection of ink plays an increasingly important role.Although the stage has not yet established green ink or environmental protection ink discrimination ...
Water-based ink resin is suitable for intaglio printing ink. The ink coating prepared with this product has good film forming ability, quick drying, high gloss, high hardness and scratch resistance, good film forming ability on the surface of paper foil and good compatibility with water-based pigment. Application characteristics 1 Good film formation 2 Suitable for a variety of substrates, good ad...
Waterborne polyurethane fabric coating agent can give the fabric a good soft and plump feel and skin feeling, and the anti-wrinkle, anti-shrinkage, resilience and flexure of the coated fabric have been greatly improved, waterproof waterproof polyurethane fabric coating agent has become the fabric manufacturers and consumers favored object.So how does waterborne polyurethane work as a waterproofing...
Printing pressure has a great influence on printing quality.Maintaining an average and constant printing pressure in the effective printing area can not only make the printing ink uniform, small color difference, but also keep the size of the printing mark.It is feasible to achieve maximum flat flat printing printing pressure But because it is the manufacturing precision of printing plate flatness...
Polyurethane sealant is widely used in civil construction, transportation and other industries: Applications in construction - filling and sealing of doors and Windows, glass, etc.; Applications in civil engineering - caulking sealing of expressways, Bridges and airstrips; Automotive applications - Assembly and sealing of Windows (mainly windshield). Polyurethane sealant has many excellent charact...
Automobile seal strip is one of the important parts of the automobile, widely used in doors, Windows, body, seats, sunroof, engine case and trunk and other parts, with waterproof, sealing, sound insulation, dust, antifreeze, shock absorption, heat preservation and energy saving important role.The rubber flocking seal occupies a very important position in the automobile seal system. The rubber floc...
Water-based adhesives have various kinds and different properties, which can adapt to the trend of environmental protection. The important properties of water-based adhesive are: solid content (non-volatile mass percentage), viscosity, emulsifier or surfactant total agent dosage, surface tension, pH value, particle size and distribution, film forming temperature, mechanical stability, etc.Com...
All staff of Sinograc Chemical went rafting in Huoshan. We had a great time and had a happy holiday. I hope everyone was as happy as us.
Due to the printing speed is too fast, add too much, high hardness of tap water, ink solvent surface tension size is different, excessive circulation stirring and other reasons lead to the production of foam, ink texture is uniform to ensure printing quality, bubble is destroyed uniformity, will reduce production efficiency.After the foam overflow in the tank, the foam flows into the roller, wet t...
Now, people's environmental awareness is getting stronger and stronger, and many glue manufacturers are also seeking to transform themselves. Some water-based glue or oil-based glue are produced. Today, we will take water-based glue and oil-based glue as an example to talk about the difference between them. First, the difference between water-based glue and oily glue The first difference is that t...
The fluidity of ink includes viscosity, adhesion, viscoelasticity, and yield value and thixotropy.It mainly depends on the nature of pigment and binder, and its manufacturing process, the content of binder directly affects the fluidity of ink. In the printing press, the flow phenomenon is mainly manifested in the following three aspects: (1) When the container is poured into the ink...
After ink roller output, the flow phenomenon is called ink transfer. In the process of printing, the thickness and uniformity of the ink layer on the surface of the image and text of the plate are achieved by a series of ink rollers. Therefore, the quality of ink transfer is directly related to the ink distribution and distribution, and the smooth transfer of ink in the whole process. Generally sp...
Ink in the transfer, distribution (from the ink hopper ink, after complex transfer and distribution, until the smooth transfer to the surface of the printing sheet to form a blot), the flow phenomenon is called the transfer of ink, it is the main body of ink operation adaptability. The transfer of ink can be understood from two aspects: On the one hand, ink transfer, uniform ink and ink roller tra...
Waterborne polyurethane: A new type of polyurethane system using water instead of organic solvent as dispersion medium, also known as water dispersed polyurethane, water polyurethane or water based polyurethane. Oily polyurethane: polyurethane system with organic solvent as dispersion medium, polyurethane system with thermoplastic linear structure. Distinguish by appearance Waterborne polyurethane...
Water based polyurethane is a kind of block copolymer containing soft segment and hard segment. The soft segment is composed of oligomer polyols, and the hard segment is composed of polyisocyanate and chain extender. It has excellent wear resistance, oil resistance, low temperature resistance, aging resistance and chemical resistance.At present, the water based polyurethane emulsion on the market ...
