家里的bathtub 会有各种不同的材料,普通的tub 有类似于plastic 的涂层,如果每次
使用完后不及时擦干,the moisture and chemicals 会deteriorate 涂层。平时最好
不要把shampoo/condition bottles 留在浴盆边,这也是浴盆老化损坏的一个重要原因。
1,为何不换个新浴缸:太麻烦,可能还要敲掉瓷砖,费用至少得上千
2,用别人来做:可以,大概400多块吧,看你的budget.对喜欢自己动手找满足感的人们
,就选
3,自己买材料油漆:homedepot 有Rust-Oleum Tub and Tile Refinishing Kit $26一
瓶,可以用来刷三层没问题
可以辊,刷,或喷。建议辊,但刷子一必备,来处理底部的四个高位曲面,那里不好油
辊。
味道很大,要保持通风,买个box fan 来吹,还必须要respirator mask.
三天后就可以在白亮如初的浴盆里relax好心情啦!希望the DIY can last long

若打磨,购买密封性能好的Dewalt D26453K或Bosch ROS20VSK就可以了,可以买个shop
vac,这些足可以了。而respirator mask很憋气,我只有在喷漆时用,因喷漆的微粒很
细小,且喷漆需要在屋里操作。打磨这种活通常在院子干,通风,会降低粉尘的吸入,
戴一般的mask即可。
凡事不可教条,每种油漆的性能不同,需先打磨试刷,找到好的方法,漆柜子是很讲究
的,打磨的平整度决定了刷漆的效果,喷漆是最好,但要求技术。

The death probably has nothing to do with 输液.
It is more likely due to respiration failure (obstruction of air pathway).
The doctor should have done an emergency trachea cut to let the patient
breath -- pretty simple procedure, can be done by anybody with any tool one
can find in order to save a life.

pop corn含石棉的话,如果没有彻底浸湿,铲的时候会产生石棉粉尘,致癌的。戴口罩
可能不够,要respirator。保险起见最好找专业人士做,做完检测一下空气中石棉含量。
另外,不去动pop corn,石棉粉尘一般不会释放出来。自己铲处理不好反倒危害更大。

国际SOS说伊波拉病毒不会通过空气传染,但又说医护人员必须戴呼吸器(不是口罩)
,要与病人保持3尺距离。
healthcare workers must wear full personal protective equipment when in
contact with Ebola patients, including appropriate respiratory protection (a
respirator).
so a key message is to stay at least 3 feet (1 metre) away from anyone who
is sick.
还说The virus can survive for hours or days, depending on the environmental
conditions,outside the body.
反正还是小心为妙,口罩确实是不够抵挡伊波拉。全球400位医护人员感染,不是个小
数字,可以说是对抗伊波拉传染的一个大失败。血的教训。
