Safety fireproof glass, by Zhengzhou directly affiliated glass factory relying on international advanced technology and technology, the latest research and development of high-tech with international level of new safety fireproof glass, the product has more than two layers of high-quality float glass and imported American refractory chemical materials in accordance with the fireproof grade, by special lamination polymerization.
The product has excellent fire and heat insulation performance, high light transmittance, wear resistance, moisture resistance, high and low temperature resistance, aging resistance, and can be widely used in theaters, hotels, opera houses, dance halls, airports, stations, docks, waiting ship halls, archives, libraries, hospitals, cultural relics museums, commercial buildings, large conference rooms, etc., public buildings, and other industrial and civil buildings with fireproof partition requirements, and can adapt to the actual needs of different building functions to provide design combinations to meet the fire performance, thermal insulation performance, Special requirements for sound insulation performance, etc.
High-strength monolithic cesium-potassium fireproof glass is a kind of curtain wall or door and window glass for building exterior walls with fireproof function, which is obtained by using physical and chemical methods to treat float glass, which can keep 84-183 minutes without bursting under the impact of 1000 flames, so as to effectively prevent the spread of flames and smoke, which is conducive to the first time to find the fire, so that people have enough time to evacuate the scene and carry out disaster relief work. Its emergence solves the fatal weakness of poor fire safety of ordinary exterior walls, and greatly improves the safety factor of glass exterior walls. Not only does it have excellent fire resistance, but it is also superior in strength, at the same thickness, it is 6-12 times stronger than float glass and 1 5-3 times stronger than tempered glass.
As a result, it can be designed with a thinner thickness or a larger area for the same wind pressure, which increases transparency and reduces cost. At the same time, it also has good machinability, which can be processed into laminated safety glass, insulating glass, coated glass, and point curtain wall glass. It can also be used as an indoor fire partition and escape channel, with a large breakthrough in the use area of a single piece, which can reach 3 meters high * 2 meters wide.
The installation method is also simple and easy to understand, and it is close to ordinary glass.

Who said that it is inconvenient to kill fish with gloves, I go to the market every day, and the fish sellers all wear gloves to kill fish, which is the kind of gloves that workers wear, which are made of hard cloth. I don't know what the material is.

Sixth: finger change exercise; The method is to repeatedly exchange the fingers of both hands in turn, so as to exercise the flexibility of the fingers and exercise the brain response and coordination.
Seventh: Relaxation Method; Relaxation is the best way to let the arms hang naturally, shake at will, swing vigorously and other series of operations to achieve coordination of various parts of the hand.

Your problem is probably common to all tennis players. Cavity plexus letter. Personally, I feel that there are the following problems:
1.It may be that the grip is wrong, so check the way you hold the grip.
2.If the grip is too tight and too hard, relax a little, the thumb should be pressed on the middle finger, the index finger should be more comfortable on the handle, and the racket can be held tightly when hitting the ball, and try to relax at other times. This may also be the main cause of calluses.
When you're hitting the ball, you try to try to relax.
3. It is possible that the action is not standardized, the right place is not hit, the handle is not suitable, the thickness may be uncomfortable or slippery, and there is also a possibility that your racket is not suitable for novices, and the dessert is too small.
I would like to give you the following suggestions.
1.It's best to use a soft sweatband! Sweatbands are actually very important for the feel of playing wood wheelball, as well as calluses or something.
2.You can wrap two sweatbands, of course, the premise is to remove the layer of sweatband carried by the handle itself, and then wrap two layers, the main thing is to prevent your fingers from touching the soft point of the sweatband.
3.Try to hold the handle relaxedly.
Well, take good care of your fingers!
I hope the calluses on your hands get better as soon as possible! ~

I'm a piano pinch learner. ,.In fact, playing the piano in winter is really a troublesome thing.
Because the hand is not flexible. That's why I'll wear gloves all the time. Then the hands are generally warmer.
But suddenly a big tune doesn't work. The only way to warm your fingers is to warm your fingers first. Playing hanon or scales is a great way to do this, but it certainly can't be too much trouble.
The first few articles of Hanon must be played all the time. And it's going to be very slow, very slow, raise your finger high, touch the keys quickly. This will also work on your granularity and finger strength.
It's tiring to play like this. Take a break and start playing tunes. But don't be too fast, from slow to fast practice, a bullet will look too low to sink.

Fingers are a guitarist's most valuable asset. Take care of your fingers and don't let them hurt in the slightest. Key points:
1. If the tip of your finger is accidentally scratched, be sure to go to the hospital to do regular anti-inflammatory work to ensure that it does not become further infected and must not leave any scars! 2. Beginners generally feel that their fingers are painful to lift upright, especially the fingertips of the left hand, and even the fingers are blistered. Generally speaking, the pain in the fingers will disappear in about a week, and to avoid blisters, you should stop immediately when you feel a slight pain in your fingers every time you practice, and practice again the next day.
However, blisters can speed up the adjustment of fingers to the strings to some extent, so don't be nervous once you have blisters, just stop practicing that finger and wait until the blisters recede. Generally speaking, after a blister once, you will never get up again, unless you are too lazy and haven't practiced for more than a few months. 3. Control the amount of finger movement. Don't practice too hard, especially if you do some advanced techniques too early, otherwise your fingers will easily hurt.
One criterion is that if your knuckles are sore, stop practicing immediately and resume practicing when you recover.
I have been studying this issue for many years, and it is important to address the flexibility, flexibility and independence of the fingers first, and then the expansion training of the fingers, I used to study classical guitar and teach you a way to hook the middle finger with the index finger and the ring finger with the little finger, and rhythmically expand the span of the middle and ring fingers,。。 Hope it helps you. If you have any questions, you can consult me.
