According to the method disclosed by the invention, microwave energy is used to heat uniformly, when the viscosity of the epoxy resin is minimum in the heating process, the small pressure is applied to the epoxy resin for a short time, so that the effect of reducing bubbles can be realized...
This study concentrates on the use of materials known as hollow glass spheres, also known as glass bubbles, to reduce the drilling fluid density below the ... B Kutlu,E Ozbayoglu,S Miska,... 被引量: 0发表: 2014年 Long-term water absorption and swelling of glass-bead filled plastics It...
The amount of air bubbles in the abrasive slurry can be minimized by pulling a vacuum during or after the mixing step. In some instances it is preferred to heat, generally in the range of 30° to 70° C. the abrasive slurry to lower the viscosity. It is important the abrasive slurry ...
provide greater packaging strength.For example, it may be possible to foam or inject air bubbles into plastic resin in such a way as to maintain the size, shape, and (importantly) the strength of the current generation of containers while reducing the amount of plastic resin used in ...
利用微波能量均匀加热减少气泡的环氧树脂成型方法 Epoxy molding method using microwave energy to reduce air bubbles uniformly heated本发明公开了一种利用微波能量均匀加热减少气泡的环氧树脂成型方法,其特征在于:包括以下步骤:(1),将环氧树脂或环氧树脂与其它复合材料置于模具中,(2),将微波发生器置于导波槽外,使得...
melt pressure, and melt state of the melt resin. D.V. Rosato and Marlene G. Rosato [15] proposed that surface defects, such as splay marks and silver streaks, are most often caused by bubbles in the melt coming from moisture, trapped air, etc. They suggest that appearance properties are...
The silicon containers were placed under a vacuum to remove air bubbles and left to polymerize for 24 h. A subsequent thermal treatment at 80 °C for 3 h was performed to finish the polymerization process. 2.3. PDA Preparation PDA synthesis was carried out by following the manufacturer’s ...
