Heavy winter maintenance of farm machinery
In general, agricultural implements have a long parking time in the winter. If they are not carefully kept and neglect the maintenance of the storage period, the damage during the parking of the implements will greatly exceed the damage during the working period. In order to prolong the service life of equipment, the following seven precautions should be taken into account during the storage period. Anti-iron parts corrosion When the farm machinery is kept in storage, it is necessary to remove the external mud, cleanse the seed, fertilizer, pesticide and crop residues in the implement and clean it with water or oil if necessary. Clean the lubricated parts and re-lubricate, such as plows, plows, spade shovels, openers, etc. After cleaning, coat the oil as much as possible to block contact with the air to prevent oxidation and rust. It is best kept in a cool, dry, ventilated room. Stored in the open air should be placed in a dry place with high ground and away from direct sunlight. It must be covered by scaffolding. Iron parts rust generally can be used the following methods: First, rosin gasoline rust. With 50 grams of rosin, add 50 grams of gasoline, mix and stir into rosin gas, and apply it to rust-free iron tools to dry it to prevent rust. The second is ammonium sulfate solution rust removal. Add 1 kg of ammonium sulfate and 20 kg of clear water. Put the rusted iron tools into it after stirring. After soaking, the rust will fall off automatically, and then rinse with clean water. Then immerse in lime milk or paint with rosin. rust. The third is rust removing vinegar. Put rusted furniture and agricultural machinery parts in vinegar, soak it out until the rust layer is easily peeled off, brush the rust with a thin wire, wash it, dry it, and apply it with anti-rust oil or petrolatum. The fourth is soda rust removal. Add baking soda in an amount of 1:500 in the tank, put the implements and agricultural machinery parts into baking soda, and remove them with clean water after a few days to remove rust. Anti-corrosion Racks, thresher barrels, drums and other wooden pieces should be wiped, dried and coated with tung oil, stored in a dry and ventilated room. Textile machinery such as canvas, improper storage and easy to be rotten. Such products can not be placed in the open air, cleaned and dried, and stored indoors in a dry and pest-free place. Anti-aging rubber The rubber parts are damp or stained with oily substances, which are prone to aging and deterioration, resulting in wrinkles and cracks, shortening the service life. Therefore, the tractor, the pump, and the flat belt or the V-belt on the harvester should be removed and hung on a ventilated and dry wall, which is prone to aging on agricultural machines for a long time. During storage and parking of tractors and harvesters, wooden blocks are used to lift the front and rear bridges of the locomotive to lift the tires off the ground, without pressure, and to maintain proper air pressure. Anti-motor damp After the motor gets wet, it will cause the internal insulation performance to drop, and even cause a short circuit in the internal line group. When it is not used for a long time, it should be placed in a dry, ventilated and clean warehouse. If the motor is stored together with pesticides, fertilizers, etc., or placed on damp mud, it will be damp and corroded after a long time and the service life will be shortened. In order to prevent the motor from getting wet, the housing should be wiped clean, dried and put into a closed plastic bag, and then put fresh lime into the bag to prevent moisture, and the effect is better. Anti-spring deformation Parts such as springs, conveyor belts, long shanks, and tires may deform due to prolonged stress or improper placement. All mechanically stressed or pulled springs must be loosened. After the tractor is parked in the storage, the clutch handle should be placed in the “closed†position. Otherwise, the clutch spring will lose its elasticity due to long-term compression and will be scrapped. The intake and exhaust valves of the engine should also be in a closed state, so that the spring can not only avoid long-term pressure, but also prevent dust from entering the cylinder and corroding the valve seat and valve to cause leakage. Remove the belt and keep it in the room. Some detachable deformable parts such as arbors should be laid flat or hung vertically. In addition, when the removed parts such as seedlings, tires, etc. are stored, they must be protected against dust accumulation, extrusion, and pressure deformation. After winter tractor operation, the cooling water should be let off to avoid freezing of the cylinder and tank. Anti-battery curing When large and medium-sized tractors are stored, the batteries should be removed and their external surfaces wiped clean and fully charged, and then petrolatum should be applied to the surfaces of the electric piles and connecting plates. Charging once every one month thereafter to prevent vulcanization or cracking. Loss prevention It is best to create files for farm implements and keep their random data. Registered cards must be established for farm machinery and tools that are parked for a long time, and the technical status, attachments, spare parts, and tools of the equipment must be recorded in detail. And do have a dedicated custody, it is strictly prohibited to disassemble parts for other purposes. Conditions should be the product production license, agricultural machinery promotion permit, product certification, "Three Guarantees" certificate, product brochures, product road signs, sales units, formal invoices and other random information, properly preserved to ensure that after-sale agricultural machinery products get normal service And when used correctly.
Plant Extract is a kind of product which is made of plant (whole or part of plant) as raw material, according to the need of the final product, through physical and chemical extraction and separation process, obtains and concentrates one or more effective components of plant without changing the structure of its effective components. At present, the product concept of Plant Extracts is broad. According to the different components of the extracted plants, glycosides, acids, polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids, etc. can be divided into vegetable oils, extracts, powder, lens and so on according to the characteristics of the final products. Plant extract is the main raw material of plant medicine preparation, and can be used in nutritional supplements, health food, cosmetics and other industries. It is the core product in the market of natural medicine and health care products. It includes Daily Chemicals, Cosmetic Raw Materials, raw materials for daily necessities, etc.
Daily chemicals refer to the industry that produces chemical products that people need in their daily life, also referred to as daily chemicals. The industrial sector that produces chemicals commonly used for chemicals and natural products. General chemicals have fixed chemical structure and physical and chemical properties. Natural products come from animals, plants or minerals, and their compositions are complex. They usually can not meet the requirements of people's daily life directly, but must be processed together with other chemicals and/or natural products to become daily chemicals with specific functions.
The main raw materials of cosmetic raw materials are commonly used as matrix raw materials and natural Additives . The general base materials for cosmetics include: oily raw materials, which are the most widely used raw materials for cosmetics, play a protective, moisturizing and softening role in skin care products, play a stereotyping and aesthetic role in the use of products; surfactants, which can reduce the surface tension of water, with decontamination, wetting, dispersion, foaming, emulsification, thickening. Functions, known as industrial monosodium glutamate; moisturizers, cream cosmetics are essential raw materials, its role is to prevent paste drying cracks, maintain skin moisture; binder, mainly used for hair glue, mousse and gelatinous mask; powder, mainly used in the manufacture of powder products; pigments, dyes, mainly used in the manufacture of cosmetic modification Products; preservatives, antioxidants, in the cosmetics shelf-life and consumer use in the process of inhibiting microbial growth; fragrance, increase cosmetic fragrance, improve product value.
Detergent is essential for people's daily life and work. It has been playing an important role in protecting human health, cleaning the environment and industrial production for a long time. Detergent Raw Materials include high foam deoiling emulsifier, nano deoiling emulsifier, high foaming essence, concentrated high foaming essence, detergent surfactant, degreasing agent and so on.
