胶化时间 meaning in English
gel time
Examples
- Determination of gel time of thermosetting powder coatings at a given temperature
热固性粉末涂料在给定温度下胶化时间的测定 - It was shown that the gel time and rf carbon aerogels properties were mainly determined by the catalyst content ( r / cat ) and reactant concentration
催化剂含量( r cat )和反应物浓度是影响凝胶化时间和气凝胶性质的主要因素。 - In comparison with sol - gel system catalyzed by potassium carbonate and sodium carbonate , the gel time was markedly shortened and the densities of the prepared carbon aerogels were obviously reduced
相对以k _ 2co _ 3和na _ 2co _ 3为催化剂的凝胶体系，凝胶化时间大大缩短，所得气凝胶密度降低。 - The tlow distance and gelating time of the nanocomposites were shorter than that of the pure pf , which meet the standard of the pf used in frictional materials . compared to the pure pf , the silica7pf nanocomposites exhibited excellent heat stability only in nitrogen atmosphere , however , so do vermiculite / pf nanocomposites in both nitrogen and air atmospheres . compared to the brake pad based pf resin , the wear rate of the present one based with silica / pf nanocomposite decreased obviously , especially in high temperature
