4 major causes of cracking of PC lampshade, T8 lamp housing solution4 major causes of cracking of PC lampshade, T8 lamp housing solution
The reasons for the cracking of the PC lamp cover can be roughly divided into two types. One is that the material is out of order, the other is artificial, and the material is out of order. Then the solution is also very simple to change the material. What is the artificial situation? What? In general, this is caused by improper installation and operation, and is subject to relatively large pressure, but relatively speaking, this situation will be relatively small. Today we will mainly look at the 4 major reasons for the cracking of the PC lampshade due to the material:
1. The stress is too large, divided into two types. First, the shape of the product itself, as well as the size of the mold itself and the stress caused by demolding. Secondly, the external stress on the product. If the stress is too large, the pc lampshade will break the molecules.
2. Repeated use. When used repeatedly, the product's molecules will undergo fission under the constant high temperature. The molecular chain will break and crack with high-quality pc lampshade. From a high-molecular substance to a low-molecular substance, the material becomes brittle.
3. Wrong choice of material filler. PC itself is a high-molecular polymer, and the molecules are linked into many elastic network structures. If the filler used for high-quality PC lampshade or the molecular weight of the filled PC lampshade is not matched. Then, the elastic mesh structure of the PC is filled with other molecular structure materials, so that the toughness of the product is destroyed, and the interaction between the molecules will become smaller, thereby cracking.
4. Environmental factors. Acid and alkaline environment, strong ultraviolet, high and low temperature (please refer to the table of environmental characteristics of PC materials for details), so in the process of using high-quality PC lampshade, especially pay attention to the environmental impact.

Example: Once a customer listens to our quotation, he will say that it is too expensive. Do n’t ask for 4 yuan for your talents. 7 yuan for your family. In fact, everyone knows that the 4 yuan lamp kit is definitely not the 7 yuan. The same, why do you say that, since 4 dollars can be bought, why would anyone choose 7 dollars? Expensiveness is often due to quality. The quality is basically derived from materials, so some customers will clearly say that last time It's cheaper to buy in other homes, but there will be problems within half a year. This time I hope to find products with a three-year warranty.
A passage often seen in the circle of friends: Market price arbitrage has become morbid, novices look at prices, veterans seek quality, and scammers have no cost. Everyone is fighting for IQ. If you care about quality, please respect its price, if what you want is cheap, please do not want to have good quality. No one will be so stupid as to drive high prices and push out old customers! Gold is valuable, reputation is priceless, the transaction is just the beginning, making a single business to make a friend, the service is endless!
