Actually I am making Polyacrylamide gel under room temperature. My current
working formula is list below:
Acrylamide (monomer) (~ 8%, wt)
bis-acrylamide (crosslinker)
Redon: Tetramethylethylenediamine/ammonium persulfate
solvent: water/ethylene (10:1)
This formula works pretty well. However, I am trying to replace water/
ethylene glycol with pure ethylene glycol but the crosslinking cannot be
initiated even after two days. I tried to vary the reaction temperature but

finish up my yearly maintenance on the car, before the North East winter

如果散热器加注口盖里面如果有沉积物或铁锈，或者冷却液太脏，就需要换。看看过程好
像也不是很复杂，和换机油差不多吧。说做就做！
先看看要什么耗材和工具。
手册里倒是没说要用什么牌子的冷却液,只是要求用好牌子的乙二醇(ethylene–glycol)基
的冷却液兑蒸馏水，乙二醇的浓度在50％到70％之间。总之浓一点，凝固点会低一些，沸
点会高一些。反正现在是夏天，用不着太低的凝固点，就1：1吧。到walmart和autozone一
看，各种牌子五花八门的还真不少，找个好点的吧。比较价格后发现还是walmart的便宜，
同样的Prestone的要便宜1块多。
至于工具，实在是没啥专用工具，只需要拧螺丝(94camry的六角螺帽直径是14mm)的工具就
足矣。
把车开上ramps开始动手。
我可不想被开水烫着，乖乖等到发动机冷了再拧开散热器口盖。

最tricky的问题是corrosive inhibitor。老coolant里常用的corrosive inhibitor有
