2. There are many blood vessels, nerves, sebaceous glands, sweat glands, etc. distributed on the human scalp, not only can dandruff and grease be removed, but also when combing. the teeth are gently stroked back and forth across the head. It can stimulate nerve endings, regulate the nerves of the head through the cerebral cortex, relax the tense state of the head, promote blood circulation, and stimulate hair follicles and sebaceous glands. The sweat glands are well nourished.

Rainwater grid
Water grid generally refers to the rainwater grid. It is welded by flat steel and twisted square steel or flat steel and flat steel. Rainwater grates have the advantages of beautiful appearance, better drainage, high strength, wide specifications and low cost, so steel grates are generally used for grates for rainwater.Grille. With the development of science and technology, resin or plastic is used to make steel bars and inorganic fillers to form a new composite water grid. AvaThe advantage is that the weight is lighter than cast iron water grid and the cost is low. is that the resistance is not as high as the cast iron water grid.
Features of the water grid
1. Light weight: The weight of the product is only about one third of that of cast iron, which is easy. to transport, install and repair, and greatly reduce the weight of the product, increased labor intensity.
2. Anti-theft: This synthetic material has no recycling value and is naturally anti-theft it is also equipped with a locking structure to prevent theft of goods in the well. This can completely prevent the occurrence of “urban black hole” accidents.
3. Strong weather resistance: This product uses polymer materials with high molecular weight and strong chemical stability as raw materials. Through scientific formula, advanced technology and equipmentcomplete technical, the product can be used at -50 °C. ℃—+150℃ for normal use.
4. High precision: Since this product is cast at high temperature, the gap between the cover and the gasket is small, which solves the problems of cast iron and cement manhole covers such as "running, jumping and ringing" tree fences, and improves product efficiency and driving comfort
5. chemical construction and has obvious acid and alkali resistance and corrosion resistance. The anti-aging index reaches level three or higher. Long life performance characteristics. cast iron grate
1. High strength: Inspection of magnesite shows that it has high compressive strength, flexural strength, impact resistance and toughness.ity. This product will not crush or damage manhole covers after long-term use and can completely eliminate "urban black hole" accidents.
2. Beautiful: The surface pattern of the magnesite manhole cover is exquisitely designed, the color is bright and adjustable, and beautifies the urban environment.
3. Easy to use and lightweight: The weight of the product is only about one third of that of cast iron, which is convenient for transportation, installation and emergency repairs, and greatly reduces labor intensity.
4. Anti-theft: Magnesite manhole covers have no recycling value and are naturally anti-theft according to customer requirements, they are equipped with a locking structure to prevent theft of goods in the well.
5. Strong weather resistance: With scientific formula, advanced technology and complete technical equipment,magnesite manhole covers can be used normally at -50℃~+300℃.
6. Resistant to acid and alkali, corrosion, wear, vehicle rolling and long service life.
