Under the mode of focusing on financing, the BT model is popular in the security market. It can be foreseen that the security platform software will get great development in the security process. The decade of prosperity before security was led by digital hard disk recorders. The security and prosperity of the platform brought by platform software is worth looking forward to. BT mode BT (Build-Transfer, construction - transfer) is actually a model of project financing, more common in all parts of the country safe city, intelligent transportation and other government projects. Due to the huge scale of the project, the total investment price in the previous period is high. To solve the government funding gap, the project construction company will pay for the project investment first, and the government will gradually pay for the project construction cost during the project construction and formal operation. At present, this model is widely implemented throughout the country, and some of the projects have also been relatively successful.
Alarm Operation The alarm operation mainly provides service for the police. The world's largest security company, ADT, USA, whose main business is the alarm service. The annual sales revenue is as much as 6 billion U.S. dollars, showing a large market share. At present, most of the services in China appear in the banking and public security industries. In a variety of forms, a third-party software platform may be constructed to monitor the system's video and alarm conditions. If there is a warning, it will be handled first, or directly to the bank security center or the public security department for assistance.
The operation and maintenance service security system is a unified system. After the delivery, there are still needs for training, maintenance, and subsequent upgrades and capacity expansion. It is also possible to use services to operate.
Training Services: Training services are currently provided free of charge by platform software contractors in the domestic market, and many do not perform well, which also affects the quality of the project after delivery. Many of the security system construction programs and concepts are very advanced and highly integrated, but after delivery, due to the low level of operators, coupled with the flow of personnel and many other reasons, many security systems did not play a role. Some role, so training is a big market, there is a lot of room for improvement.
System operation and maintenance services: System operation and maintenance services are mainly completed in the construction of the security system, and some routine maintenance of the system after delivery, such as system inspection or system troubleshooting. System operation and maintenance services are the main service market for security platform software companies, and they are also the most direct market. However, they are not doing well at present. Many engineering integrators do not have the ability to do so, and platform software providers have relatively no money to make, and not Develop this market.
Renovation, upgrading, and expansion services: During the operation and maintenance of a system, with the recommendation of time, product upgrades, equipment aging, and software updates, the system has the need for transformation, upgrading, expansion, and so on. The market has now been discovered by everyone and started to dominate the competition by platform software.
Potassium Carbonate, Potassium Bicarbonate and Magnesium Carbonate can be used as pH regulator, nutrient, food additive, pharmaceutical ingridient, yeast, baking powder, swelling agent, additive for beverage, infant formula powder etc.
Sodium carbonate ("soda" or "natron") and potassium carbonate ("potash") have been used since antiquity for cleaning and preservation, as well as for the manufacture of glass. Carbonates are widely used in industry, e.g. in iron smelting, as a raw material for Portland cement and lime manufacture, in the composition of ceramic glazes, in food additive and beverage ingredients, in pharmaceutical raw materials etc..
In aqueous solution, carbonate, bicarbonate, carbon dioxide, and carbonic acid exist together in a dynamic equilibrium. In strongly basic conditions, the carbonate ion predominates, while in weakly basic conditions, the bicarbonate ion is prevalent. In more acid conditions, aqueous carbon dioxide, CO2(aq), is the main form, which, with water, H2O, is in equilibrium with carbonic acid – the equilibrium lies strongly towards carbon dioxide. Thus sodium carbonate is basic, sodium bicarbonate is weakly basic, while carbon dioxide itself is a weak acid.
Carbonated water is formed by dissolving CO2 in water under pressure. When the partial pressure of CO2 is reduced, for example when a can of soda is opened, the equilibrium for each of the forms of carbonate (carbonate, bicarbonate, carbon dioxide, and carbonic acid) shifts until the concentration of CO2 in the solution is equal to the solubility of CO2 at that temperature and pressure. In living systems an enzyme, carbonic anhydrase, speeds the interconversion of CO2 and carbonic acid.
Although the carbonate salts of most metals are insoluble in water, the same is not true of the bicarbonate salts. In solution this equilibrium between carbonate, bicarbonate, carbon dioxide and carbonic acid changes consonant to changing temperature and pressure conditions. In the case of metal ions with insoluble carbonates, e.g. CaCO3, formation of insoluble compounds results. This is an explanation for the buildup of scale inside pipes caused by hard water.
Potassium carbonate (K2CO3) is a white salt, which is soluble in water (insoluble in ethanol)[2] and forms a strongly alkaline solution. It can be made as the product of potassium hydroxide's absorbent reaction with carbon dioxide. It is deliquescent, often appearing a damp or wet solid. Potassium carbonate is used in the production of soap and glass.
potassium carbonate is prepared commercially by the electrolysis of Potassium Chloride. The resulting potassium hydroxide is then carbonated using carbon dioxide to form potassium carbonate, which is often used to produce other Potassium compounds.
Potassium carbonate was historically for soap, glass, and china production.
in cuisine, where it has many traditional uses. It is an ingredient in the production of grass jelly, a food consumed in Chinese and Southeast Asian cuisines, as well as Chinese noodles and moon cake. It is used to tenderize tripe. German gingerbread recipes often use potassium carbonate as a baking agent.
in the production of cocoa powder to balance the pH (i.e., reduce the acidity) of natural cocoa beans; it also enhances aroma.
as a Buffering Agent in the production of mead or wine.
in antique documents, it is reported to have been used to soften hard water.
as a fire suppressant in extinguishing deep-fat fryers and various other B class-related fires.
in condensed aerosol fire suppression, although as the byproduct of potassium nitrate.
as an ingredient in welding fluxes, and in the flux coating on arc-welding rods.
as an animal feed ingredient to satisfy the potassium requirements of farmed animals such as broiler breeders.
