The expert group led by Jiang Shicheng, an academician of the Chinese Academy of Engineering, recently conducted a site visit to Qingdao Jifa Group's “highly liquid-missing chitosan fiber and medical materials†project. The expert group consistently made the project “total technical achievement of the projectâ€. Appraisal opinion of the international advanced level and the product quality has reached the international leading level.
According to the research and development personnel, the chitosan fiber medical material has high moisture absorption and high moisturizing properties. After rapidly absorbing the wound exudate, it expands to form a gel, which can lock moisture and maintain humidity. It is an upgrade of medical dressing raw materials. product. Medical dressings processed with chitosan fiber have the effects of bacteriostatic, hemostasis, promoting healing, non-adhesion, and reducing scar formation. Wound care can reduce the use of antibiotics, and the dressing cycle can be shortened without frequent dressing changes. The production technology of the high-hygroscopic chitosan fiber of Jimei Group has been authorized by three invention patents and has complete independent intellectual property rights.
NFT does not give average support to roots. Typically, the roots sit in a long sloping channel irrigation (Fig. 1.1). The nutrient is introduced into the high class of the canal and allowed to flow over the roots after which it drains into the nutrient tank. This is then re-pumped back into the channel to repeat the watering process.
This feed cycle can be intermittent or continuous. An & lsquo; The intermittent 'rss cycle is controlled by the clock and repeated several times per hour. this is sometimes called the "NFT pulse".
