Water-resistant and high-temperature grease is special, and fully synthetic water-resistant grease or fully synthetic silicone grease should be used.
1) High-temperature bearing lubrication, using fully synthetic high-temperature motor bearing grease, fully synthetic high-temperature high-speed bearing grease;
2) High-temperature anti-jam assembly, using fully synthetic high-temperature anti-jam grease;
3) 600 degrees - 1200 degrees high temperature lubrication, the use of fully synthetic ultra-high temperature grease;
4) High temperature waterproof, use fully synthetic water-resistant grease or fully synthetic lubricating silicone grease;
Common brands include: Shanghai Tiger Head Hotolube, Krupp, and German Keyjet.

There are a lot of chemistry, but generally speaking, they are boring.
For example, when I was in college, although I often visited special museums, most of them were liberal arts museums, and it was rare for anyone to like to read science books.
However, reading some professional books can enrich knowledge and expand experience, and if you can read it, it is great Inorganic, organic, physicochemical, chemical principles, etc., have their own series of supporting teaching aids
I've read a few books before, and it's just a boring alternative when I'm bored Organic Element Trace Quantitative Analysis Wang Jober, edited by Gao Min.
Engineering CAD Fundamentals and Applications Yang Songlin, edited by Yu Yifeng (although he studied chemistry, the computer is very practical).
Chemistry and Life Yu Wenguang, edited by Li Hairong.
Ceramic Technology Zhang Rui, Wang Hailong, Xu Hongliang editors-in-chief.
Building Energy Saving Technology, edited by Wang Na.
Water Analytical Chemistry Huang Junli, Wu Mingsong, eds.
Fine Chemicals for Industry and Mineral Edited by Wang Dongmin, Zhang Yihe, and Li Duanle.
In fact, it is also very good to read the biographies of Marie Curie and Edison in your spare time, and it is also very encouraging to read literary works and relax

In the tank! Many couriers are like this, collect as much money as possible, and bear as little responsibility as possible. I used to use the house xx express to break my things, and when I complained to their complaint department, they actually said: Please support the development of private enterprises, you understand!
Agree with "Jiajia Bubu"! You're too young! It's not grown yet! Let's wait until after the age of 25!
My express delivery has nothing to do with Jiayunmei, it is Pinduoduo's merchant because there is no goods, and the platform will deal with it for a long time, so it has created a fake Jiayunmei's express tracking number, as well as tracking information, and it shows that it has been signed, contact the merchant's customer service, say rest, and then apply for a return before the customer service let the customer service change other reasons, saying that even if I complain to the merchant, the platform will not deal with them, this kind of deception is too hateful! There is no goods to tell, just refund directly, and make a fake courier!
Detailed ways to distinguish the real from the fake: 1. The packaging of the licensed goods is exquisite, and there are special marks on the bottom of the can, the inside of the lid, the handle and other inconspicuous places; And the fake packaging is mostly coarse. 2. There is a laser anti-counterfeiting mark in the circle in the lower right corner of the front of the can, and the letters have an obvious 3D sense when observed from different angles, while the counterfeit products have no three-dimensional sense and the difference in brightness is large.
Friend, you ask too much information in one breath, don't blame the superior brother for not being able to answer for you. >>>More
