PMMA color paste instructions
Based on the production feature of PMMA industry, combined with foreign technology, our company adapts the efficient dispersant which is independently research and developed, and have a production and management system in accordance with the ISO900. We are specialized in the production color paste. The use of color paste can avoid the problem of difficult to weigh, color deviation and poor dispersion defects caused by using color powder directly. It is the indispensable raw materials in production of display boards, sanitary ware, sculpture.
1. Stability: the raw materials are from the internationally well-known companies to ensure that the high degree of stability of color hue, shade, brightness and saturation.
2. easy to disperse: strict refinement process and good dispersant ensure the excellent dispersion in the very low hardness of the compound
3. resistance to weather: based on SGS test GB/T 1865-2009 xenon arc aging standard, the color fading will be under 20% in 3 years and the hue change is also very small.
4. comprehensive: variety, it can be equipped with all the visible spectrum of color according to the principle of three primary colors. Special color can be customized.
5. standardization: the paste and its related additives have been standardized, as long as the customer reserves a small number of models of products, they can meet the timely proofing and emergency production needs.
1. Stir well before using
2. With 1 (color paste): 3 (raw material) ratio, high-speed stirring 20min, and then into the bubble barrel, but also high-speed mixing with clinker evenly mixed about 50min.
3. When adding a paste, do not stir the second catalyst with the cream.
4. If use OK-1 opacifier, no need to dissolve with raw materials, OK-1 0.5% = 1% of the liquid can be directly into the clinker bucket and paste high-speed mixing.
5. It is recommended that the viscosity of the MMA sheet be at least 45 seconds (to be coated with four cups of viscometer), preferably at least 60 seconds (depending on the product). If the color paste concentration to be added to 2% (bathtub), the viscosity of 80 seconds or more is better to avoid double-sided problem.
6. The color paste storage time up to more than a year, if the time to place a longer color cream, because the proportion of the problem of toner, there will be part of the separation phenomenon, but the use of high-speed mixing mixer can be used.
Method for the ratio of adding the color paste
In general, the production of sheet of 3mm 1% of the proportion, take the length and width of 1220mm * 2440mm of 3mm thickness of the plate as an example, it is 1220mm * 2440mm * 3mm * 1.19Kg / m3 (MMA specific gravity) ≒ 10.7KG, then 1% of the paste was added to 10.7 kg * 0.01 = 0.107 kg = 107 g
1. With the same size but different thickness, the usage is as the same as the thickness of 3mm, the special size of the customer needs to be adjusted.
2. Special Note: Because the secondary material is less likely to control, so for some specific colors or models, in the operation of under 2.5mm thin plate, we recommend the ok-1 opacifier, with which the precipitation and shadow will be reduced to lightest. Some color liquid can be used by ps liquid (styrene), but also depending on the actual situation.
3. Storage: Store in a cool, dark, ventilated place. Shelf life: 12 months
