Biomass energy refers to the energy that plant chlorophyll converts solar energy into chemical energy stored in biomass. Currently, the development and utilization technology is mainly to convert solid biomass into combustible gas, tar, etc. through thermochemical conversion technology. The chemical conversion technology converts biomass into biogas, alcohol, etc. under the fermentation of microorganisms, and compresses biomass into high-density solid fuel by compaction molding technology. The energy contained in biomass fuels is formed by photosynthesis of plants and is a renewable energy source. The use of this fuel, if it reaches the balance of output and consumption, does not increase the carbon dioxide in the atmosphere, but excessive consumption such as deforestation and depletion of organic matter that can be returned to the soil will destroy the balance of production and consumption. The biomass is used to generate biogas in the biogas digesters for the lighting, and the residue is still a good organic fertilizer. The production of ethanol methanol from biomass can be used as an automotive fuel.
It features a nail specifically designed for wood that, when inserted into the wood, is very firmly embedded. If the wood is not rotten, it is impossible to pull out, even if forced out will bring out the nearby wood. There is a point to pay attention to, wood screw must be screwed in with a screwdriver, do not use hammer in, will damage the wood around.
The advantage of the wood screw is that it has stronger consolidation ability than the nail joint, and can be removed and replaced, so it is more convenient to use without damaging the wood surface. 1. The common types of wood Screws are made of iron and copper. Depending on the head of the screw, there are round head, flat head and Oval Head. On the head of the screw, there are two kinds of slotted screws and cross slotted screws. Generally, round head screws are made of soft steel and are blue in colour, polished flat head screws, Oval head screws are usually cadmium-chromium plated and are commonly used for installation of loose-leaf, Hook and other hardware accessories. Specifications to rod diameter, length and nail head type to determine the purchase of the box as a unit. 2. Install wood screw tool the screwdriver is its loading and unloading tool, the shape matches the wood screw head trough shape to have a word and the cross shape two kinds; in addition has one kind to mount on the arcuate drill the special screwdriver, is suitable for loading and unloading the bigger wood screw, the utility model has the advantages of convenient use and labor saving.
