Changzhou Contact: Charles Guocai Tel :0519-889026188890281888900007E-mail: market @ yibu. corn Features: fast drying,[link widoczny dla zalogowanych], after the spraying of liquid surface area increased significantly, in the hot air flow, the moment a 98, 95 can be evaporated moisture, drying time is only a few seconds to complete, especially suitable for drying heat sensitive materials. Product has a good uniformity, fluidity and solubility, high purity and good quality. Production process is simplified, convenient control. 40% moisture content for a 60% (up to the special materials 9O) into the liquid to a dried powder products, dried without crushing and screening to reduce the production processes, improve product purity. Product size, bulk density, moisture,[link widoczny dla zalogowanych], within a certain range can be adjusted by changing the operating conditions, control and management are very convenient. ・ 15 ・ [link widoczny dla zalogowanych] cmasteq.
