Disposable mops are a one time use products,They are the products made by 100% non-woven cloth or very cheap cleaning fabrics that just can use a short time.
Disposable mops will cost you less on initial purchase but are also a one-time use product.with low costs and after used will damage.use a disposable mop will not have any soil build-up or chemical residue from previous cleaning procedures. Disposable Microfiber Mops can increase your worker`s productivity and reduce labor costs. While you use reusable Microfiber Dust Mop or Microfiber Tube Mop,we need wash after each time.
Water-based ink composition
Water-based ink is a combination of specific water-based polymer resins, pigments, water, and additives added by the physical and chemical process of ink, referred to as ink. Water-based ink uses water as a solvent. After the ink is transferred to the substrate, the water evaporates into the environment or penetrates into the substrate. The ink is dried with the evaporation of moisture. Aqueous polymer resin is the most important component of water-based ink. It plays a role as a binder in ink, allowing the pigment to be uniformly dispersed, giving the ink a certain degree of fluidity, and providing adhesion to the substrate material, making the ink Can form a uniform ink layer after printing. Alkali-soluble resins are currently used for research and development. These resins can be dissolved in water to make water-based binders that become insoluble in water after printing and drying.
The hue of water-based inks is mainly determined by the pigments. The pigments are evenly distributed in the binder in the state of particles. The pigment particles can absorb, reflect, refract, and transmit light, and thus can exhibit a certain color. General requirements Pigments have a bright color, suitable coloring power and hiding power, and a high degree of dispersion. In addition, depending on the purpose of use, it is also possible to select different resistance solvents. The role of the solvent is to dissolve the resin, so that the ink has a certain degree of fluidity, can be successfully transferred during the printing process, and adjust the viscosity and drying properties of the ink. Auxiliaries have a great influence on ink performance and are an indispensable part of ink painting. The commonly used additives in inks include pH stabilizers, slow drying agents, defoamers, dilutants, and the like.
Water-based ink's environmental safety features
Water-based inks are distinguished from solvent-based inks, the most prominent feature being the dissolving vehicle used. Solvent-based inks are dissolved in organic solvents such as toluene, ethyl acetate, and ethanol, while aqueous inks are dissolved in water and a small amount of alcohol (about 3% to 5%). Due to the use of water as a carrier for dissolving, aqueous inks have significant environmental and safety features: safe, non-toxic, non-hazardous, non-inflammable, non-explosive, and virtually free of volatile organic gases. Mainly in the following four aspects:
1. No pollution to the atmosphere;
2. Reducing residual poisons on the surface of printed matter to ensure food hygiene and safety;
3. Reduce resource consumption and reduce environmental costs;
4. Improve the safety of the operating environment and ensure the health of the contact operators.
Application of water-based inks
From the printing point of view, water-based inks are not yet suitable for offset printing, and its main application areas are flexographic printing, gravure printing and screen printing.
Countries that have used water-based screen printing inks in large quantities are Sweden, Germany and the United States. Since the 1980s, light and matt water-based inks have been developed internationally for fabric printing, paper, PVC, PS, aluminum foil and metal on-line printing. The development of screen printing in our country is very fast, and the progress in the development and popularization of screen printing water ink is slow. What is gratifying is that China has attracted people's attention in the research and development of screen printing inks. After several years of hard work, we have achieved some results. According to reports, screen-printed water-based inks have been applied to printing materials such as paper and plastics in China.
