The network shows that more than 90% of the people are willing to switch to LED lights

The traditional light bulb mainly uses electric current to pass through the tungsten wire to generate the light source. Compared with the LED light bulb, the electric energy is directly converted into light energy. The traditional light bulb consumes more energy than the LED light bulb, and with the awareness of energy conservation in recent years, the LED light bulb has become a public. One of the choices when buying a light bulb, but in the face of the price of LED bulbs, is the public buying it?

Will you consider changing the LED tube (light bulb) in the future? According to the online survey, for the above-mentioned problems, 34.6% of the people who choose “will definitely”, 57.3% who choose “may”, and 6.8% who choose “may not” and “must not” and 1.3%. In other words, more than 90% of the people will consider replacing LED bulbs in the future.

In addition to less power consumption than conventional light bulbs, LED bulbs have longer lamp life than conventional bulbs. In addition, traditional bulbs contain some ultraviolet light, while LED bulbs do not contain ultraviolet light. They may be healthier for the human body, but LED bulbs are at a price. Part of it is also higher than the traditional light bulb, so the public can change the price, you can buy a cheap and large bowl of LED bulbs.

This survey conducted a questionnaire survey on members of the Boss Online Network for over 13 years old. The survey time was 2015/3/22 (day), and 1377 copies of valid samples were collected. At 95% confidence level, positive and negative errors were used. It is 2.64%. The implementation method is that Pollster Online Survey conducts sample surveys for members through the website market platform; Bostel sends emails to invite members to fill out the questionnaires issued by Boss, conduct market research and market. Information gathering. Bostel members have passed the mobile phone newsletter and email certification.

Silica Sol Casting

Compared with large complex thin - wall castings, civil products have lower requirements on casting quality. However, for the latter, shorten the production cycle, improve the production efficiency of the problem becomes more prominent. The gelation process of common silica sol mainly depends on the dehydration and drying of silica sol, which takes longer time than the gelation of chemical hardening ethyl silicate. Ethyl silicate shell using ammonia dry each layer can be completed in 2h, and the final hardening of silica sol generally takes more than 12h, for some deep holes and other difficult to dry parts of the need for a longer time. At the same time, because the Investment Casting shell needs to be made in layers, each layer needs to be fully dried, to ensure that the lower shell immersion coating will not cause the problem of remelting off, and immersion coating itself, water will be immersed in the dried shell, resulting in a long overall drying cycle. It is a schematic diagram of the production cycle of silica sol shell investment casting under general conditions. As can be seen from the figure, shell making time accounts for more than 50% of the whole casting production cycle. To shorten the delivery time and shell making cycle is the core of the problem. The key factors to shorten the shell-making period can be divided into two aspects: internal cause and external cause. The main internal cause is the characteristics of the binder, and the external cause is the drying condition.

Silica Sol Casting industry in China is developing rapidly and its application is also very extensive.
