With the improvement of people’s living standards, heating in winter has entered the vision of everyone, installing air conditioners, installing floor heating, installing radiators, installing electric floor heating, and so on. As the main heating methods appearing on the market today, it is summarized that there are 9 kinds of Heating, the following brief introduction.
First, centralized heating: urban heating suitable residence: ordinary residential, office building principle: the urban heating network, regional heating network or central heating boiler room as a source of heat heating. Advantages: the technology is more mature, safe, reliable, the use of price Cheap. Disadvantages: 1, heating time and temperature can not control their own, heating comfort is poor. 2, heat sink is not beautiful space, affecting the decoration effect. 3, difficult to pay is difficult to solve the old hard problems, especially the new community The low occupancy rate leads to no heating. 4. When the temperature of the heat sink reaches 80 degrees, dust clusters will be generated, causing the wall above the heating to be covered with dust. 5. No heat source before and after the heating period, heating charges increase year by year. 6. Heating pipe The network facilities must be maintained, repaired, and replaced.
Second, domestic coal-fired boilers: home heating advantages: 1, heating time free. 2, heating furnace can provide domestic hot water at the same time. Disadvantages: 1, need someone at home to guard, dirty dirty, low comfort. 2, heating furnace use The service life is about 6 years, and the update cost should be borne by the owner. 3. Burning dust is serious and there is air pollution. 4. The pipeline radiator occupies the inner area of ​​the cover and affects the appearance.
Third, hot air-type air conditioners: warming fast principle: the use of electrical heating. Advantages: 1, ready to use, warming faster. 2, easy installation, removable. Disadvantages: 1, resulting in dry and static, is not conducive to human health .2, higher costs.
Fourth, home central air-conditioning system: Comfort and safety Applicable places: Villa advantages: 1, high grade, good shape, high comfort. 2, air-cooled with a fresh air system is more comfortable. 3, temperature and time can be preset. 4 , suitable for larger areas of low-density residential and villas. Disadvantages: 1, a larger initial investment, higher operating costs. 2, can not enjoy the national trough electricity preferential policies.
5. Electric boiler for home use: free temperature adjustment Applicable residence: Villa principle: It adopts electric energy heating. Advantages: 1. Small floor area, simple installation, convenient operation. 2. Heating can also provide domestic hot water. The advantage is that it has a variety of time and temperature control preset functions. Disadvantages: Larger initial investment, high operating costs, the product is not suitable for the use of low valley heat storage heating.
Heating film heating: Applicable residence: Fine decoration apartment principle: With electricity as energy source, a pure resistive heating element made of special conductive ink printed between two layers of polyester film is equipped with an independent temperature control device. Most of the ceiling type, but also a small part of the laying in the wall. With adjustable temperature, comfortable and environmentally friendly, long life, maintenance-free features. Advantages: 1, no indoor radiator, room usage area can be increased by 2% to 3% ,Easy to decorate and place the furniture .2, generally do not need to maintain. 3, is a clean energy, no pollution .4, can use the thermostat to adjust the room temperature .5, no traditional heating of hot feeling, temperature uniformity. Disadvantages: 1, electric The temperature rise of the film is slow, it generally takes 1 to 1.5 hours to reach 18 degrees Celsius. 2. The system installation must be synchronized with the decoration, and can not be nailed, drilled, etc. on the ceiling. It is not conducive to ceiling molding. 3. Poor electrical energy supply. Unstable or too high electricity rates are not suitable for the community.
7. Hot water floor heating: The room temperature is gradually reduced from the bottom up. Applicable residences: Residential principle: Floor heating is achieved by radiating heat evenly into the room through a heating pipe buried under the ground. This can be achieved by a separate gas heating stove and factory. Boilers, residential boiler rooms and other ways to provide heat source. Advantages: 1, the ground temperature is uniform, the room temperature gradually decreases from the bottom up, high comfort, 2. Air convection weakened, there is a good degree of air cleanliness. 3, and other heating methods Compared to the more energy-efficient, the energy-saving rate is about 10%.4. It is conducive to interior decoration, an increase of 2% to 3% of indoor use area. 5, is conducive to floor insulation. Disadvantages: 1, the height of 8-10 cm Occupied left and right. 2. Underground pipelines are easy to be damaged during surface decoration. 3. Because the water temperature is not adjusted accurately, it is better to use floor tiles or composite flooring. 4. The set temperature should not be too high, otherwise it will greatly reduce the service life of the pipeline. , Small boiler heat pump often start and flame combustion, noise, there is a certain pollution problem.
8. Household wall-mounted gas heating: free temperature adjustment Applicable residence: low-density residential principle: usually a fireplace is installed in the kitchen or balcony, and the sky-burning gas is used to heat the gas. The advantages: 1, free time for heating time The temperature of each room can be adjusted in a range. 2. Some heating stoves can provide domestic hot water at the same time. Disadvantages: 1. To ensure the use of gas, the newly-increased residential community has no gas heating capacity. 2. Heating The service life of the furnace is about 6-8 years, and the replacement cost should be borne by the owner. 3. When there is no one at home, the low-temperature operation (antifreeze) needs to be maintained at about 4 degrees. 4. The heat pump often starts and the flame combustion noise is relatively loud. Air pollution problem. 5. Occupied area within the cover, affecting the appearance.
Nine, intelligent electric floor heating system: health, safety, energy saving, beautiful
Applicable residence: residential, office building principle: electricity as energy, mainly with heating cable heating room for indoor heating. Advantages: 1, the ground temperature is uniform, the room temperature decreases from the bottom up, comfort is high, there is no traditional heating sense of heat 2 Reduced air convection, good air cleanliness, no pollution, no noise. 3, compared with other heating methods, more energy-saving, energy saving rate of about 10% -20%. 4, installation, easy to use without maintenance, Separate households are intelligently controlled, and the temperature, time and cost are determined by themselves.

According to the different production methods of calcium carbonate, calcium carbonate can be divided into Heavy Calcium Carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. White solid, tasteless and odorless. There are two forms of amorphous and crystalline. The crystal type can be divided into orthorhombic crystal system and hexagonal crystal system, which are columnar or diamond-shaped.
Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. The addition of calcium carbonate has a certain effect on improving certain properties of plastic products and expanding their application range. In plastic processing, they can reduce resin shrinkage, improve rheology, and control viscosity. It can also play the following roles:
(1) Improve the dimensional stability of plastic products;
(2) Improve the hardness and rigidity of plastic products;
(3) Improve plastic processing performance;
(4) Improve the heat resistance of plastic products;
(5) Improve the astigmatism of plastics;
(6) It can make the product have some special properties;
(7) Reduce the cost of plastic products.
