The winter temperature drops significantly. Under the influence of cold stimulation, the pig is susceptible to disease and affects normal growth. If we can take correct and feasible methods, scientifically prevent cold and increase temperature, it will not only promote the healthy fattening of pigs, but also reduce the occurrence of various respiratory and intestinal diseases and increase the income of pig farmers. The author now introduces several common methods of insulation.
The site of the pig house to be repaired should be high, dry and sunny. It is necessary to plug the window holes on the north, west and east sides, and to repair the roof and gaps on the four walls in time. The window and ventilation holes of the pig house should be 1-1.5 meters from the ground, and can adjust the size of the hole to keep the temperature stable.
Hanging wind curtains are used to cover the entire doors and windows of pig houses before the winter with a plastic sheet to keep them warm and cold. In the direction of the building, straw or corn stalks are used to form wind barriers or windrows to prevent the wind from invading the shed.
Build housing estates Build housing estates in housing estates. Plastic film and felt can be used. The plastic film can transmit light and heat, the felt can breathe and accumulate temperature, and can increase the temperature of 5°C-7°C. The construction of houses in housing estates is characterized by low investment, simple production and quick results, but it should be adapted to local conditions. Since it is simple, it can be built in the form of suspended ceilings with a height of about 1.8 meters. At the same time, a ventilated window is left at the same time to provide ventilation and ventilation.
Adding litter 15-20 cm thick sawdust, rice husks, and hay are added to the bed of pigs. In addition to heat preservation, moisture absorption and dehumidification are also possible. Pay attention to constantly check and update the urine wet hay, found that the pig urine should promptly remove the wet grass and replace the hay to keep the pig house dry and comfortable. Spray peracetic acid at noon in good weather, or add lime under litter to remove ammonia and moisture, and properly separate the joints of the houses in the house to eliminate ammonia and moisture in the house.
Increase the stocking density to feed the scattered pigs in groups. The number of pigs in the house can be increased by 30%-50% compared with the summer. The use of the body temperature between the pigs can increase the temperature. Attention should be paid when pigs enter a new pig when it is dark. They should be sprayed with wine or low concentration of Lycopene and then gregarious. At the same time, the breeder needs to observe for a few hours to prevent the pig from fighting. It is also possible to choose the sunny day to rush the pigs outside to enjoy the sun, enhance the exercise and increase the pig's resistance to cold weather.
I. Introduction
Cationic fixing agent is polyelectrolyte, consists of a series of organic synthesis with low molecular weight and strong cationic, which is generally 100% cationic. Product character is aqueous solution.
II. Performance Indicators:
1. Appearance: colorless to pale yellow viscous liquid
2. Solid content: ≥ 50%
3. PH: 2 ~ 6
4. Viscosity: 50 ~ 200 mpa.s
III. Application Field
Used in paper pulp as a cationic fixing agent. Usually the slurry contains colloidal particles consisted of fiber materials, additives and water, which are with anionic charge and interfere the papermaking process, so it is also known as anionic trash; the interference is mainly in the following aspects:
1. Influence wet chemical additives` normal function, especially for cationic retention and drainage aids, sizing agent; or cause to increase the amount of wet chemical additives;
2. Deposits in the paper machine system; interfere the efficient papermaking process.
3. COD discharge of sewage systems, increasing the load on the sewage treatment plant. Recommended for use in mechanical pulp, chemi-mechanical pulp, and secondary fiber pulp slurry and coating waste stuff. Anionic trash neutralized by fixing agent can be bonded to the fibers so as to be taken away by paper sheets.
IV. Methods of Application
Adding methods: excellent water-solubility; can spread out in water instantly. Dosing pump is generally used to drive it into a static mixer or a mixing pump , mixed with water, diluted to about 0.2% of the dissolved solution, and then into the slurry system.
Adding point: the general adding point is in the front of flow system, that is, before the machine chest or fan pump; or add in the pulp plant. Which is taken into consideration for the reaction time of the cationic fixing agent polymer molecules and garbage, also need to time and space for other wet end additives. According to the slurry source, sometimes you need to select two or more points to add. When the slurry contains a source of coated broke, generally requires additional anionic trash fixative in the transport of the paper sheet.
Adding dosage: anionic trash content in the slurry is usually gauged by the cationic charge contents measured by PCD (particle charge analyzer) in the slurry. The measure will directly show the dosage tips, but the real dosage depends on the practical application. For general slurry, the recommend amount is in the range of 0.3kg ~1.8kg/t dry pulp.
V. Safe Operation
1. Cationic fixing agent is a water-soluble polymer, dissolved in water in a highly slippery state and avoid to spill on the floor. If spill, shall timely absorb with sand, sawdust.
2. Wear gloves, wear overalls to operate.
VI. Storage
The product should be kept sealed, stored in cool, dry, ventilated places, and appropriate temperature should be 10-30 ℃.
VII. Package
200 kg plastic drums or 1000 kg PE IBC drum.
