查询词典 gelatin process

PVA-2080 is one of the important dispersing agents to produce loose polyvinyl chlorid. At present KH-20 is mainly imported from Japan to take the place of the traditional gelatin to produce high quality PVC in our country. In order to solve this problem, we exploit PVA-2080 to replace the foreign products. The experiment includes two steps of polymerization and a process of partial alcohlysis. After a number of trials, we get a product of white particles.Its average degree of alcoholysis is 80.77% and t...

利用热分析研究了干凝胶自燃烧过程，并且利用X衍射、透射电子显微镜研究了pH值、温度、成胶时间以及燃烧温度对MnZn铁氧体的晶体结构、晶体组成和粒径大小的关系。

It was shown that the absorption peaks of amine and amide groups of gelatin were shifted in HDPE/PE-g-MAH/Gelatin blends because of the reaction of PE-g-MAH with gelatin. The addition of PE-g-MAH made the increase of HDPE glass transition temperature. The compatibilizing effect of PE-g-MAH was due to the crystal compatibility produced by forming the co-crystals of HDPE, PE-g-MAH and PE-g-MAH-g-gelatin. The blends of EAA and gelatin were prepared by melting process and the compatibility of the blends was also studied.

红外光谱分析结果表明：体系中明胶的氨基吸收峰、酰胺Ⅱ带吸收峰峰位发生了明显的变化；二甲苯和水抽提实验表明，在熔融共混过程中EAA与明胶发生了反应；DMA测试共混物的玻璃化转变温度发现：两组分的玻璃化转变温度差值减小；SEM的实验结果表明，共混物中明胶的表面有接枝物形成。

The blends of PE-g-MAH and gelatin were prepared by melting process and the compatibility of PE-g-MAH and gelatin in blends were characterized. The results of FTIR showed that the characteristic absorption band peaks of amine and amide groups of gelatin were shifted in PE-g-MAH/Gelatin blends, the equilibrium values of torque were higher with the increase of blending temperature, which proved that graft copolymer PE-g-MAH-g-gelatin was formed during the preparation process, and the amount of PE-g-MAH-g-gelatin was increased with increasing the amount of PE-g-MAH. SEM micrographs exhibited that there was PE-g-MAH-g-gelatin formed in surface of gelatin phase.

通过红外光谱分析、HAAKE流变分析、抽提等实验证明：共混物中明胶的氨基、酰胺基团吸收峰峰位发生了明显的变化；在熔融共混过程中，随着温度的提高，平衡扭矩增大；明胶与PE-g-MAH发生了反应形成PE-g-MAH-g-明胶接枝共聚物，而且随着PE-g-MAH用量的增加，形成接枝共聚物的量也提高；SEM的实验结果表明，在明胶的表面确有接枝物形成；通过DMA测试共混物的玻璃化转变温度，发现两组分的玻璃化转变温度差值减小，二者的相容性提高，实现了共混体系的自增容。

Gelatin microsphere is firstly made by encapsulating bFGF into gelatin by special manufacture process, then this microsphere was combinated into PLGA conduit or PLGA film.when used, we need only pack the injury peripheral nerve, injury spinal cord, wounded pars encephalic with the PLGA conduit. The conduit or film can slowly release buff which would be absorbed by around tissues.bFGF was already proved to be nutritious to the regeneration and alive of neuron and protect injury neuron.bFGF can also promote morphogenesia and division of nerve cell which would raise the survival rate of neuron, guide the generation of axon etc.bFGF is one of the important factors of sustaining the normal survival of cholinergic nerve.

使用时，只需将此材料贴敷外周损伤神经伤患处，脊髓伤口，或在脑部开颅手术后填充于术后创面，可有效地在伤口局部缓慢地释放并由机体组织吸收bFGF等神经营养因子。bFGF等已被证明具有神经营养作用，可促进神经元的再生与存活，保护受损的神经元。bFGF等对神经细胞兼有促进形态发生与分裂作用，具有提高神经元的成活率、诱导轴突向外生长等功能，是维持前脑基底部胆碱能神经元正常生存的重要因素。
