Enthalpy of wetting process by heating air-conditioning system in the application of spinning
) Then (5), equation (6) is a linear regression equation, the experimental data (vpj,) dx-_ multiplication with the most calculated A, B,microsoft outlook, m, n, r, s, heat exchange efficiency to be TI. , Tl2 test formula. Enthalpy of wetting process by heating the first and second heat exchange efficiency of testing the formula in Table 1. 33 No. 1 Vo1.33. №.

Double of the spray O. 9283 (vP) 0.075 /. tom4 four kinds of wet process steam consumption compared by experiment and calculated four kinds of wet process steam consumption of comparison, as shown in Table 2. As can be seen from Table 2, the process of consumption by enthalpy steam humidification temperature at least,ugg botas, consumption of steam enthalpy largest humidification process. After the first isothermal enthalpy and isothermal humidification humidification process between the consumption of steam between the two. Mainly by enthalpy full advantage of the process of heating humidifying steam saturation enthalpy of water. Because the soft drink mixer is a direct hybrid heating, while other processes are using the room (on the next page 26) of sheet material properties of the shape of the hollow fiber culture conditions. 5 Outlook since the last century, 80 years, set off in the development worldwide of chitin, chitosan boom, the world are increasing chitin, chitosan and development efforts in the United States, Japan, South Korea, India, Netherlands, Norway, Canada, Poland and France have been able to produce,microsoft office 2010, Japan is taking the forefront in the country. 80 years from the last century, China began producing chitosan, a capacity of domestic 180t, main producers Jianhu Jinsheng Group Jiangsu, Zhejiang rings County chemical plant, a new chemical plant in Jiangsu Taicang County, Fujian Normal run Factory, Shanghai Reagent Factory, etc., production are concentrated in the coastal shrimp, crab gathering place. Although chitosan has a soluble, but the development of its fiber much later than the chitin fibers. The first report is wrapped in 2 units of air flow in the steam consumption of the process names kg (vapor) / kg (air) temperature by wetting enthalpy enthalpy 8.82 × 103 after the first isothermal isothermal humidification humidification 11.82 × 10-3 11.56 × 10-3 13.25 × 10-3 enthalpy then heated humidification, the air heater,uggs bestellen, the enthalpy of saturated condensate is not being used. Can be seen from Table 2, the use of air heater heating the air temperature is higher, the saturated condensate heat is wasted, the more units the greater the air flow of steam consumption. Tests to prove: the process of humidification heating operation by enthalpy easy to adjust; the air in the washer after the same initial and final state parameters, the process by enthalpy steam consumption of less heating humidification; for high temperature and humidity requirements of the occasion. IU4 \.5% acetic acid. and subsequently there have been some other solvents such as acetic acid / urea mixture, spinning liquid is used in different solidification. In 1993, found that chitin fibers can be spun chitosan fibers and then by derived anhydride acetylation acetylation, which provides a production line of chitin and chitosan fiber a more economical solution. also found that acetylation process is affected by processing conditions such as reaction time,tiffany schmuck, temperature, and anhydride and the ratio of the weight of such fibers effect. When the time integration of chitosan fiber loss, acetylation fibers have a dry and wet strength. Recently, at room temperature, saturated acid containing l0% ammonium sulfate solution as coagulation developed a good solution new functional bio-materials - chitin / silk fibroin silk fiber. using similar methods, also developed a chitin / protein, chitin / starch, chitosan / starch, chitosan / collagen mixed fiber . chitin polymer chains of the two hydroxyl groups and two hydroxyl groups in the chitosan polymer and amino occur on chemical reaction to produce highly value the development of new functional materials, the development of chitin, chitosan fiber products very high economic and social benefits, an attractive charm, good market prospects. |
