Coloring plastics technology improvements
Pigment surface, adding a direct relationship between the amount of paint formulations the number of i West 『core. Practice shows that can be used per square meter area of 2 mg pigment dispersant efficiency (Table 2) is more appropriate. Table 2 wet pigment dispersant effective amount of the required 2. Deepen the color to deepen the color to do business involves a lot of processing technology, but the use of highly efficient dispersant, the quality and cost savings from the process also occurs with the similar benefits,[link widoczny dla zalogowanych], and increased color depth 3O, production has also been enhanced. Usage: to roll or roll band in high-speed mixing, internal mixing, extrusion or rolling, such as conventional dispersants used in the program efficiently, regardless of what kind of processing. Shall be according to the following procedure: 1. Pre-polymer mixing equipment will add | 2. Efficient dispersant added and thoroughly mixed with the polymer I3. Adding pigments, fillers, excipients, and other important components, and for mixed} 4. Regular way, that is extruded or combination of twin-roll processing of mixed sets of objects. Must strictly follow the above procedures, in order to save high over the surface of the polymer dispersant. Making it highly efficient dispersant and direct contact with the greatest possibilities. If the efficient while adding dispersant and pigment premix equipment, and the above can be relatively lower. : To simplify the calculation, can paint filler and 5% of the rice root absorption CO. Introduction of the progress Kwong Yan Hua Liu Qiongying (South China Agricultural University) by the roots of plants absorb CO. Research (coz - including co ±, HCO3 one, HCOa, etc.) began in the thirties. Livingston et al (1934) has proposed plants absorb from the soil solution CO. Transferred along with the transpiration stream to the shoots of plants as a carbon source supply units role in the theory of light. Hartel has reported the transfer of each liter 177 ~ 570mgCOz transpiration stream to the shoot. Overstreet, Ruben, etc. in the forties on the use of the fixed CO: barley roots was studied the role of carbon sequestration, the fifties Court Sarnoff (Kursanov) had such young soybean root absorption by CO conducted a study, Craft et al (1955) have also reported the onion , pea roots on the role of carbon Chou, Mitsui, Kurihara (1959) studied the application of tracer contained in the fertilizer in the absorption of carbon assimilation by the roots, which defined the rice (paddy field conditions) than in upland (upland conditions), and wheat and other crops with more efficient by adding dispersant root resorption, and a preliminary test. 3. Liquid dye proved efficient in the liquid dye dispersant added after the rheological properties of the liquid dye will be well improved. Low viscosity of the liquid produced by the dye can be more easily filtered. In the plastics industry using high dispersion of wattle, the ability to produce very 3OCO2. Jackson et al (1959) confirmed that plant roots on the role of CO in the week set by phosphoenolpyruvate carboxylase (PhOsphoenolpyruvateCarboxylase) achieved. Rice often has obvious roots in silicon uptake and concentration characteristics of straw dry matter and therefore in general silicon content up to 10%. As we all know, the role of this pest and disease resistance of rice is important. Tengen et al (1977) found that absorption of rice not only has the concentration of silicon (s】) characteristics, but also absorb a similar concentration and chemical properties of silicon germanium (oeOD and carbon (c) characteristics, as carbon, silicon, germanium in the element cycle table for the same group element. to make necessary the issue of rice through root absorption of C re-evaluation. So in recent years on the issue of rice through root uptake of CO revival. mountains, etc. (1979) to applied organic fertilizer as c source absorbed by the roots of rice c issues that rice rhizosphere soil than in non-rhizosphere soil COa concentration was higher, but faded port (1982,1986) and Wada (1983), who found that with the growth of rice, rice farming area in the total carbonate concentration in soil solution than no rice cultivation area in the total carbonate concentration in soil solution excellent color brightness and uniformity, reduced production costs, increase productivity, with the continuous improvement of its performance, it will make plastic products industry presents a new look. ● Covent more [1] PlasticsEngineeringt2, 1989 [2] ibid.tEngineering, 3,1989 [3] PlasticsTechology, 1 ~ 3. 1989
