Fiberglass Grating
The fiberglass grating also named FRP grating & fiberglass grid, and the fiberglass grating panels can be made into FRP grating cover, fiberglass walkway grating, fiberglass trench grating and so on.
The fiberglass grating is light in weight and has good elasticity, so it can be cut freely during the installation process, without using lifting equipment, and only a small amount of labor and cutting tools are required. Because the FRP grid is made of non-metallic materials, the corrosion resistance of the FRP grid is very good. The FRP grid will not rust and rust under the chemical medium, nor will it damage the structure of the material.
Beyond that, the color of fiberglass grating including yellow, gray, green and as your demands.

Ginger oil processing technology
Ginger is rich in ginger, Gingerol and Eucalyptol and many other nutrients. Ginger oil extracted from ginger has unique odor and aroma, and it has the effects of qi and phlegm, blood circulation, and anti-virus. It can be used not only for seasoning and pickling, but also Extraction of flavors, etc., can also be used as raw materials for medicine and light industry. The processing of high-quality ginger oil has low cost and significant benefits. 1, the choice of materials and processing will be fresh ginger wash, cut into 4 ~ 5 mm thick ginger, dried, charcoal fire conditions available baking. With the slow fire lasting 60C, slowly increase to about 80C, diligent turning to prevent roast ginger coke baking. Generally 7 kilograms of fresh ginger can bake 1 kilogram of ginger. After the ginger is dry, it can be sent to the grinder for smashing. The old sieve should be used in the pulverizer (not too airtight when too finely distilled, too thick and affecting the oil rate), the ginger slice will be crushed into rice grains, and then used. 2, equipment installation and requirements (1) install steamer. The floor is first built, and a large iron pan with a diameter of 1.2 meters is placed on the floor stove. There is an active wooden frame on the pot, and a cloth sack is used as a steaming pad to prevent the ginger powder from leaking into the bottom of the pot. A pot of 2 meters in height, 6 centimeters in wall thickness, 1.25 inches in diameter at the lower end, and 0.9 meters in diameter at the upper mouth can be used to hold 50 kilograms of ginger powder at a time. After loading, a small wooden barrel is added above the large wooden barrel. The barrel height is 0.7 meters, the lower diameter is 0.9 meters, and the upper diameter is 0.5 meters. Finally, put a small iron pot inside the small wooden barrel, add cold water. (2) Install the cooling tank. The barrel can be made of wood or concrete and placed next to the cooker. In order to dissipate heat, its shape should be large and small, 1.75 meters in height, and a bamboo tube with a midpoint in the barrel for use as inlet water for cooling. (3) Install the plate intestine. Wrap around a bamboo tube made of white iron or tin on a bamboo tube in a cooling drum and make a total of 9 laps and immerse it in cold water. A small bamboo tube is installed at the small barrel and connected with the upper end of the pancreatic tube. The lower end of the pancreatic tube is connected to the oil separator. (4) Install the oil separator. The oil separator can be large or small, but it must be made of white iron to prevent corrosion. Due to the different density of oil and water, the positions of the outlet and outlet holes should be installed one by one. 3, refining operations and note elements (1) charge. Ginger powder inside the whole wooden barrel should be packed evenly and elastically to avoid sticking of ginger powder into the air, so as to facilitate the smooth flow of gas. Otherwise, loose air and fast oil, tight gas stagnation and slow oil delivery, and it is not easy to net out, will affect the oil rate and extend the oil time. Before filling, add enough water to the cauldron. Normally, the water level must be 4-5 cm below the steaming pad, and the first water intake should be about 1.5 tons. And insert a water inlet pipe at the bottom of the vat to facilitate adding water at any time so as not to dry it. 2) Leakproof. In all junctures between vats and kegs, vats and wok, smear with mud to prevent air leakage. If the pancreatic tube is welded, it must be soldered without gaps so that the ginger oil will not sink in the cooling water. (3) Cooling. The water should be constantly flowing. If it is interrupted, the oil rate will be affected. After the oil-water mixed steam enters the intestine of the pan. The outlet temperature should not exceed 30-35C, otherwise, oil and gas will escape from the outlet hole of the oil separator and affect the oil rate, so it is necessary to cool down in time and cool it with warm water. (4) The heat. When the fire is refined, the water in the pot should keep boiling. When the oil is out, the firepower must be large and urgent, and when the coal is added, the fire should be less. The fire in the stove should be covered. Do not concentrate on one side or a little. When the oil is exhausted, use a big fire to slam a bang. When the oil outlet stops, you can turn off the stove. According to the above method, 3 kg of high-quality ginger oil can be extracted for every 100 kilograms of fresh ginger.
