(1) Coal fired stoves are the most economical heating equipment, but they must be fireproof when used. If the chicken house has good insulation properties, generally 15-20 m2 can be used with a stove. Keep it 15 cm away from the stove and isolate it with iron wire or brick to prevent chicks from entering the stove and burning or burning with litter. The stove flue should be placed according to the wind direction so as to prevent the chimney mouth from constantly blowing wind and the smoke from the stove.
(2) Another method is fire. Digging the ditch under the ground in the house, from the middle of the house to the other end, requires a certain slope of the fire, the beginning of the fire for the base furnace, the use of coal or firewood heating methods. In order to make the temperature in the house relatively uniform, the fire path near the fire end of the stove is higher than the ground, and the fire path far away from the fire end is lower than the ground. The fire can also be set on the ground, leading from one end of the house to the other, and then turning back and forth along the front and back walls. Put a layer of fine sand or bedding on the fire floor. If the heat insulation performance of the house is poor, a plastic film can be placed on the ceiling of the ground to improve the insulation effect.
Imported Bio-based Plastic Additives
Plastic additives, also known as plastic additives, are compounds that must be added to polymers (synthetic resins) to improve their processing properties or to improve the properties of the resin itself. For example, in order to reduce the molding temperature of PVC resin, to make the product soft and added plasticizer; Another example is to add foaming agent in order to prepare light weight, anti - vibration, heat insulation, sound insulation foam plastics; The thermal decomposition temperature of some plastics is very close to the molding temperature, and the molding cannot be done without adding heat stabilizer. Therefore, the plastic assistant agent occupies a particularly important position in the plastic forming process. A class of auxiliary agents for plastic molding products, including plasticizer, heat stabilizer, antioxidant, light stabilizer, flame retardant, foaming agent, antistatic agent, mildew agent, colorant and whitening agent (see pigment), filler, coupling agent, lubricant, mold release agent and so on. Colorants, brighteners and fillers are not special plastics chemicals, but the general use of materials.
