The longevity of product features and appearance depends on daily maintenance. The correct method can extend the effective life of the inner door. Paying attention to the inner door in the home and taking care of it slightly will have unexpected results. The first thing is to teach everyone how to wipe the door that covers the entire interior door. The neat and bright door panel will make the inner door of the home look good.
For daily cleaning of the door panel, use a soft, dry cotton cloth or silk wipe. Wiping with a hard or hard (eg, dusty) medium may scratch the surface; if the inner door panel is heavily stained, use a neutral detergent or special furniture cleaner. After cleaning the stain first , then dry rub. But do not rinse with water.
If the door panel is made of resin or metal plate, remove the slight scratches on the surface, and use a soft cloth to take a small amount of toothpaste for repeated cleaning.
If the door panels are made of wood or painted sheets, waxing on a regular basis is an effective way to keep the surface bright and bright, whereas glass or resin panels do not require waxing.
In fact, how to clean hardware and hardware is the soul of the entire interior door, including handles, locks, hinges, etc., which are small in size, a major role. The key to the service life of the inner door is the maintenance of the hardware.
Stainless steel handles and stainless steel other hardware can be wiped with brighteners, can add light.
The moving parts such as hinges, hanging wheels, and casters may lose their performance due to the adhesion of dust during long-term movement. One or two drops of oil can be kept smooth every half year or so.
When the lock cylinder is not flexible enough to rotate, a small amount of black powder may be scraped from the pencil lead and lightly blown into the lock hole. This is because the graphite component is a very good solid lubricant. Do not instill lubricating oil as this will make it easier to adhere to dust.
Special attention should be paid to the direction in which the handle is rotated and the dead force should be avoided. In particular, children should be educated. Do not hang on the doorknob and it is both prone to danger and may cause damage to the inner door.
Solar cells use sunlight to generate electricity. As long as the sun shines on the battery, it will continue to generate electricity. It is a clean energy with the advantages of safety, reliability, no noise and no consumption of raw materials. It has the advantages of great convenience for residents in remote areas. So what is the working principle of solar energy? Today we'll explore it. Solar cell is a device that directly converts light into electric energy through photochemical effect. When sunlight shines on the semiconductor pn junction, a new hole (electron pair) is formed. Under the action of the electric field, the hole flows from the N region to the p region, and the electron flows from the p region to the N region. After the circuit is connected, a current is formed to convert light energy into electric energy.Solar panel, also known as solar cell module, is a kind of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. It is an assembly composed of several solar cells assembled on a plate in a certain way. It is the core part of the solar power generation system.The earth, the green home for human survival.
With the development of human civilization, it has gradually become a victim of economic growth. Clean energy is imminent.
The sun concentrates 99.87 percent of the mass of the solar system, and one twenty-two percent of the energy radiates to the earth, becoming the main source of photosynthetic heat on the earth. Solar energy is one of the cleanest, most lasting and most magical energy of all.
