Firstly, polyacrylamide with 26 million molecular weight was compounded in lab through establishing optimum compounding initiator proportionality of 1:1. 3 and mass concentration of 170 mgL^(-1), temperature of 10 ℃, acrylamide mass percentage of 25%, electrical conductivity of 3.6 μSm^(-1) and pH value of 6.57. The salt-resistance, thermal endurance and shear-resistance of polyacrylamide could be enhanced b introducing sulfonic acid group or styrene sulfonate group or drawing the two groups above at the same time. Secondly, chelator HEDP, bactericide isoquinoline ketone and oxygen scavenger thiourea were optimized to improve the compatibility of polyacrylamide and formation water.

As for the mesh screen type, its volume multiplied by 100% its porosity was the desirable filling amount. Having considered the forgoing findings, the researchers add up the amounts of the above two types as the filling amount of the composite micro structure, with the filling fluid being acetone. In fabricating the heat spreader, a copper pipe is added to serve the filling purpose. What is more, because the manufacturing process is not carried out in a totally clean environment, there is some noncondensible gas left, which will have a negative effect on the performance of the heat spreader. Consequently, the copper pipe has to be reserved so that the exhaust gases can be evacuated after the filling is done.
Kempers 文中可知,沟槽结构之填充量以微结构体积之80%为最佳,网格结构则是以网格体积乘上孔隙率(porosity,φ)之100%为最佳,故本研究便以两者之加总做为复合式微结构之填充量,填充液为丙酮;在均温基板之制造程序中,会加装一铜管做充填之用,且而由于制造过程并非于一完全干净之环境下完成,故板内会有一些不利于均温基板作用之非凝结性气体noncondensible gas (NCG残留,因此铜管需保留一定的长度,以方便充填完成后将废气排出之用。
