5.FAQ
1)How many tons does your factory can supply each moth?
30000tons/month
2)How to quarantee the quality of the products?
you can arrange SGS&BV or other quality inspection.
3) why you buy from me?
We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.
- Q: For example, sulfates can emit SO2 or SO3 gas. If this were to occur in this experiment, would the % H2O calculated from the data be too high or too low? Explain.
- You would measure the mass lost, and you would assume that this is equal to the amount of water that was in the sample. So decomposition would add to the mass lost during heating and this would lead you to overestimate the amount of water that was in the sample, and overestimate the %h20.
- Q: How to get an inorganic salt
- Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
- Q: Like the role of B, Fe, Mg, Ca, Mn, Cu, Cl, P, S, N ...., the more specific the better (college entrance examination range)
- 1. constitute the body tissue material .2. Regulate the physiological function .3. To participate in the regulation of body fluid balance and maintain the body's acid-base balance .4 cells of some complex compounds of the important components
- Q: What are the disadvantages of inorganic salt deficiency and too much
- The role of inorganic salts in plant life Plants require the most inorganic salts to be nitrogen-containing, phosphorus-containing and potassium-containing inorganic salts. These three types of inorganic salts have different effects in plant life. Lack of performance nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown. P: Promote the development of seedlings and the opening of flowers so that the fruit and seed are mature early. Lack of performance: the plant is particularly short, leaves were green, and purple. Potassium: Stable stem to promote starch formation. Lack of performance: stems weak, easy to lodging, leaves the edge and the tip was brown, and gradually dry. In addition to these three types of inorganic salts, plants also require many types of inorganic salts. Among them, the demand for some inorganic salts is very small, but they are in the life of the plant also plays a very important role. For example, the lack of iron-containing inorganic salts, fruit trees will be yellow leaf disease; lack of boron-containing inorganic salts, rape will be "spent" (only flowering fruit)
- Q: By balancing the benefits of dietary supplementation with inorganic salts, what are the advantages and disadvantages of taking health care agents?
- There will be no imbalance in the state, and those survey reports are often too exaggerated unbalanced side to emphasize the use of a balanced diet. You may want to talk about how the natural diet through the general way to add the advantages of inorganic salts, and the advantages and disadvantages of taking health care agents
- Q: Can inorganic salts act as stabilizers for emulsified asphalt?
- Heze Tongren Road Machinery Co., Ltd. is a asphalt heating and storage equipment as the main body, set road maintenance equipment production, asphalt library design and transformation of technical services, to undertake asphalt library / depot and other construction and installation, industrial pipelines and chemical equipment The installation of the installation of the boiler, the installation of steel structures and accessories sales, such as integrated services in one company.
- Q: Is calcium carbide inactive?
- Calcium carbide, the chemical formula for the CaC2, not inorganic salts. Salt refers to the metal ions and acid ions of the compound, calcium carbide does not have the corresponding acid.
- Q: Is all the inorganic salts in the body related to life activities?
- Sugar is the most important material for the human body, all the activities of the human body, including learning, walking, digestion and breathing, etc., which are the most important substances in the human body. Consumption of energy (about 70%) mainly from the carbohydrates, fat is the body of the energy material, the protein is the basic material of human cells, but also to provide energy, vitamins are neither the main raw material of the organization, nor the supply of energy Material, but it has an important role in the life activities of the human body; inorganic salts constitute an important raw material of human tissue, water is the main component of cells. Which protein, sugar, fat, vitamins can burn for organic matter, and water, inorganic salts can not burn as inorganic.
- Q: What is the difference between "organic salt" and "inorganic salt"? What is the difference between "organic salt" and "inorganic salt"?
- Organic salts are organic acids with alkali (carboxylic acid) occurs in the reaction of the salt is called organic salt.
- Q: is table salt organic or inorganic, why?
- if its found in nature its organic if its made by man its synthetic. table salt is found in the ocean so i guess it would be organic.
