Stone, as a fashion, high-grade building materials, I believe many people do not understand the price , function, and type of stone care . Stone care is due to the natural environment, human factors, stone itself caused by the stone pollution, weathering and lesions, through chemical protection, cleaning, disease management and other physical and chemical combination of refurbishment, polishing and recrystallization hardening process and other processes, so that the restoration of stone The original "look" and improve its decorative effect. Now, the common stone in the market is mainly marble, granite, etc. The quality and appearance of various man-made stones are not inferior to natural stone. However, care must be taken when using natural or man-made stones. So, how should stone care? Do you understand the latest stone care prices ? If you are still bothering about this, you may wish to follow me to learn about it!
Stone Care Industry Overview
Due to the deterioration of the natural environment, dust, industrial waste gas, steam turbine exhaust, acid rain, and other pollutants can easily cause pollution to stone used in construction. Once the building stone is contaminated, cleaning is very difficult. If poor cleaning agents are used, the stains will be forcibly removed, which can easily damage the stone and accelerate the deterioration of the stone. In a modern building, in addition to perfect structural design, the entire exterior can't be ignored. The application of domestic stone in the interior and exterior of the building is becoming more and more common, and the maintenance of the stone is increasingly attracting attention from architects, construction companies and owners.
Stone care knowledge
The choice of stone is an important part in green home improvement. Stone is loved by home-improvement consumers for its characteristics of fire resistance, cold resistance, and pressure resistance. Natural stone and man-made stone need our special care to be more durable at home.
1, marble. It is soft, resistant to acid and alkali, poor weather resistance, easily absorbed oil, water and other liquids, easily scratched. The best protection for the polished surface marble is to pre-protect it with a water- and oil-resistant protective agent before the marble is put into use. Daily use Neutral detergents are regularly cleaned and must not be cleaned with acid cleaners.
2, limestone. Easy to absorb oils and other aqueous liquids, easily scratched and corroded by acidic substances, more susceptible to contamination than marble. Most limestones are porous and absorbent. It can be cleaned regularly with daily use of neutral detergent.
3, granite. Color darker, acid and alkali, anti-weathering. However, its surface is also porous, and it has strong water absorption and can be contaminated. Use a permeable protective agent as a pre-treatment and daily use a neutral or slightly acidic cleaner.
4, artificial stone. Applicable to the ground, stoves, etc. Daily maintenance can use neutral or weak alkaline cleaners.
In addition, if the maintenance of light-colored stone requires special care. It should normally be done before the installation of permeability protection treatment, maintenance in the future use of neutral or weak alkaline stone cleaner.
How to care for stone
Stone care, mainly because of the environment, man-made, stone itself and other reasons caused by weathering, lesions, after chemical treatment, reproduction of the original appearance of the stone, which is the renovation of the stone. General stone encounter external wall seepage, pollution, weathering, etc. will cause gloss wear and other issues, this time we need to carry out professional care of the stone. Under normal circumstances, the stone needs to be processed in the following aspects:
1. Stone exterior wall seepage and pollution: Wipe with water, no need to use other cleaning agents.
2. Prevention of water spot: Use multifunctional protective agent or special stone protection agent before construction.
3, Bai Hua's treatment: stone surface for protection and strengthen the sealing part of the waterproof function.
4. Treatment of rust spots: The use of strong scavenger can effectively remove rust and do not harm the stone. It is best to perform protection before installation.
5, the treatment of stains: Select the appropriate stone special cleaning agents can be effectively removed.
6, wax scale treatment: the use of decontamination and removal of wax, can effectively remove the stone surface and the pores within the wax and does not harm the stone gloss, in addition to wax, use multi-functional protective agent.
7, spit yellow (grass rope yellow) treatment: the use of multi-functional scavenger can be followed by protection products for protection, can effectively prevent the re-emergence of vomiting.
8, the treatment of wear: stone maintenance agent for surface treatment, a regular surface protection treatment.
Stone care prices how
Stone care is due to the natural environment, human factors, stone itself caused by the stone pollution, weathering and lesions, through chemical protection, cleaning, disease management and other physical and chemical combination of refurbishment, polishing and recrystallization hardening process and other processes, so that the restoration of stone The original "look" and improve its decorative effect.
Now the market is generally selling about 40-50 yuan a square meter, the quality is better, the price will be relatively expensive, the price difference is relatively different prices are different, there are brands are also relatively important, mainly to see Your own choice.

What are food additives?
Substances that are added to food to maintain or improve the safety, freshness, taste, texture, or appearance of food are known as food additives. Some food additives have been in use for centuries for preservation – such as salt (in meats such as bacon or dried fish), sugar (in marmalade), or sulfur dioxide (in wine).
Many different food additives have been developed over time to meet the needs of food production, as making food on a large scale is very different from making them on a small scale at home. Additives are needed to ensure processed food remains safe and in good condition throughout its journey from factories or industrial kitchens, during transportation to warehouses and shops, and finally to consumers.
The use of food additives is only justified when their use has a technological need, does not mislead consumers, and serves a well-defined technological function, such as to preserve the nutritional quality of the food or enhance the stability of the food.
Food additives can be derived from plants, animals, or minerals, or they can be synthetic. They are added intentionally to food to perform certain technological purposes which consumers often take for granted. There are several thousand food additives used, all of which are designed to do a specific job in making food safer or more appealing. WHO, together with FAO, groups food additives into 3 broad categories based on their function.
Flavouring agents
Flavouring agents – which are added to food to improve aroma or taste – make up the greatest number of additives used in foods. There are hundreds of varieties of flavourings used in a wide variety of foods, from confectionery and soft drinks to cereal, cake, and yoghurt. Natural flavouring agents include nut, fruit and spice blends, as well as those derived from vegetables and wine. In addition, there are flavourings that imitate natural flavours.
Enzyme preparations
Enzyme preparations are a type of additive that may or may not end up in the final food product. Enzymes are naturally-occurring proteins that boost biochemical reactions by breaking down larger molecules into their smaller building blocks. They can be obtained by extraction from plants or animal products or from micro-organisms such as bacteria and are used as alternatives to chemical-based technology. They are mainly used in baking (to improve the dough), for manufacturing fruit juices (to increase yields), in wine making and brewing (to improve fermentation), as well as in cheese manufacturing (to improve curd formation).
Other additives
Other food additives are used for a variety of reasons, such as preservation, colouring, and sweetening. They are added when food is prepared, packaged, transported, or stored, and they eventually become a component of the food.
Preservatives can slow decomposition caused by mould, air, bacteria, or yeast. In addition to maintaining the quality of the food, preservatives help control contamination that can cause foodborne illness, including life-threatening botulism.
Colouring is added to food to replace colours lost during preparation, or to make food look more attractive.
Non-sugar sweeteners are often used as an alternative to sugar because they contribute fewer or no calories when added to food.
What are feed additives?
According to the European Commission's commonly accepted definition,
Feed additives are products used in animal nutrition for purposes of improving the quality of feed and the quality of food from animal origin, or to improve the animals` performance and health, e.g. providing enhanced digestibility of the feed materials."
You thought that animals ate plants, or grass or some other `food` natural to their ilk. But in reality, in today`s factory farms, feeding livestock is a complicated endeavor fraught with controversy and split opinions.
According to a 2010 report by MarketsandMarkets, a market research company, the global feed additives market is expected to reach $18.7 billion by 2016. That`s no small industry.
There are four general types of feed additives:
- Sensory Additives – these stimulate an animals appetite so that they naturally want to eat more.
- Nutritional Additives – these provide a particular nutrient that may be deficient in an animal`s diet.
- Zootechnical Additive – these improve the overall nutritional value of an animal`s diet through additives in the feed.
- Coccidiostats and Histomonostats – these are feed additives which are antibiotics, intended to kill or inhibit protozoa (bacteria/micro-organisms). These have been banned in Europe since 2009 and replaced with probiotic alternatives.
