So, how can we choose a glass glue that works well in construction and decoration, with strong adhesion, pure color, and the same price? Industry experts believe that consumers only need to have the following common sense, buy a good glass glue is Easy.
1. Do not understand the product, not rush to buy. Some consumers purchased glass glue without knowing the basic knowledge of the product, and found many problems in the process of use. Such as: What is the difference between acidic gel and neutral gel? Why only structural adhesive can achieve structural bonding between glass? Why some transparent glass adhesive will change color? ... If you buy before you understand the classification and use of glass glue , restrictions, methods of use and shelf life, construction can certainly not only save expenses, but also reduce the rework in construction, but also extend the life of glass adhesive.
2. Don't plan and save money. Although glass glue has been widely used in construction projects or decoration, most users still put cheap products in the first place. As long as the project Party A does not specify the glass glue brand, it is inevitable that low-price glue is selected. However, the use of low-cost rubber not only affects the quality of the project and its useful life, but more importantly, it can easily lead to rework, delays in the construction period, and even liability accidents. In addition, in order to win huge profits, unscrupulous traders are still making hands on their packaging. Using thick bottles to reduce the weight of plastics and using inferior glue to replace brand plastics, the profits they earn are on the price. A low-grade glass glue of the same weight is 3 times cheaper than the brand glass glue, but the viscosity and pulling force of the brand glass glue are 3-20 times stronger than the low-grade glass glue, and the service life is 10-50 times longer. Therefore, the engineering unit can not save time, shop around to better quality of the project; consumers can not be cheap, so as not to affect the interior decoration life.
3. Do not know the performance, do not blindly use. There are many kinds of glass glue in the market, such as acidic glass glue, neutral weathering glue, neutral structure of silicic acid, neutral mildewproof glue, hollow glass glue, special aluminum-plastic board glue, and bathroom mold-proof special glue, etc. The classification properties, applicability, use restrictions and construction methods of glass glue are not completely understood, and more are never touched. Some consumers regard glass glue as a "universal glue". After one year, they found that the place where the glass glue was used was peeled off and discolored. Originally, different architectural materials were chosen to have different properties of glass glue. Therefore, the blind use of glass glue is one of the conditions for purchasing suitable products.
So, what should you pay attention to when purchasing glass glue?
1. Recognize the brand. An effective registered trademark, clear image identification, reasonable price positioning, and perfect after-sales service are the standards for the identification of branded products.
2. Look at the packaging. A look at the cartons on the name, factory name, specifications, origin, color, date of manufacture, whether there is a certificate, quality assurance, product inspection report inside the carton; second, see the use of the plastic bottle, usage, precautions, etc. Clear and complete; third, see if the net content is accurate, the manufacturer must mark the model number and net content on the bottle.
3. Check the quality of the glue. One smell, two gloss, three check particles, four look bubbles, five test cure effects, six test pull and viscosity

The bearings for automobile wheels are composed of two sets of tapered roller bearings or ball bearings, and the installation, oiling, sealing and clearance adjustment of the bearings are carried out in the automobile production line. This structure makes it difficult to assemble, costly, and unreliable in automobile production plants, and the bearings need to be cleaned, oiled and adjusted when the car is maintained at the repair point.
The hub bearing unit is developed on the basis of standard Angular Contact Ball Bearings and tapered roller bearings, which integrates the two sets of bearings, which has good assembly performance, can omit clearance adjustment, light weight, compact structure, large load capacity, can be pre-loaded with grease for sealed bearings, omitted external hub seals and free from maintenance, etc., has been widely used in cars, and has a tendency to gradually expand its application in trucks.
In the process of use, it is affected by axial load, shock load and radial centrifugal force when rotating at high speed, in addition, because the fork thrust and the reaction force of the separation lever are not in the same straight line, a torsional moment is also formed. The clutch Release Bearing has poor working conditions, intermittently rotates at high speed and bears high-speed friction, high temperature, poor lubrication conditions, and no cooling conditions.
