How to identify the quality of compound fertilizer
Compound fertilizer is a multi-element compound fertilizer made by re-granulation of two or more single fertilizers. Most manufacturers use urea, ammonium sulfate, and ammonium carbonate as nitrogen sources, and ammonium chloride is also used as a nitrogen source. Potassium chloride or potassium sulfate is used as a potassium source, and general calcium, monoammonium phosphate, and calcium magnesium phosphate are used as phosphorus sources. Depending on the needs of the crop, compound fertilizers with different contents of nitrogen, phosphorus and potassium are formulated. Some are also made into special fertilizers and long-term special fertilizers. Then how to identify the quality of compound fertilizer, the following points of view, for the reference of farmers friends. 1. Look at the outer packaging of the regular manufacturer's product packaging is more standardized, printed product name, trademark, national standards, production license number, general NPK ratio, total nutrient content, net weight, manufacturer, site of the compound fertilizer And contact telephone and so on. The "s" marked on the bag is potassium sulfate as the source of potassium, and no or "c1" is based on potassium chloride as the source of potassium. The purchase should be based on the planting crop. However, the quality of compound fertilizers produced by some non-regular manufacturers is poor, and the printed items are not complete nor standardized. 2. Look at the appearance of fertilizer The products produced by regular manufacturers are uniform, uniform in color, free from caking, and have good water-solubility. The compound fertilizer which generally uses ammonium carbonate as a nitrogen source dissolves faster than urea as a nitrogen source, and the columnar extrusion granulation dissolves faster than the spherical one. Such as bagged compound fertilizer agglomeration, if it is based on urea as a nitrogen source, and the knot of the block is broken, the quality is no problem, will not affect the fertilizer effect after application, otherwise the fertilizer effect is not good. 3. How to judge the price of compound fertilizer There are many varieties of compound fertilizer in the market. The difference is in the nutrient content, and some are in the same proportion of nitrogen, phosphorus, and potassium in the nutrient content level. When buying fertilizer, it is unscientific to only look at the price, not to see the content, which is the lowest price to buy. A bag of fertilizer is not necessarily cheap. Such as 85 yuan 1 bag to buy nitrogen: phosphorus: potassium = 18:10:6 total nutrient content of 34% of the compound fertilizer than to spend 90 yuan to buy a bag of nitrogen: phosphorus: potassium = 27:9:9 total nutrients The content of 45% of the compound fertilizer is expensive. Although the price of the former is low, the total nutrient content is also low, averaging 2.5 yuan per nutrient, the second fertilizer is expensive, and the total nutrient content is also high, averaging 2.0 yuan per nutrient. Similarly spent 85 yuan to buy 1 bag of fertilizer content of 45% of the compound fertilizer, buy nitrogen: phosphorus: potassium = 12:18:15 than buy nitrogen: phosphorus: potassium = 15:15:15 value, because the market is single Fertilizer, buy a nitrogen need 1.74 yuan, buy a phosphorus need 2.15 yuan, spend the same money to buy phosphorus high on the cheap.
A mixture of Cosmetic Raw Materials, which is made up of various raw materials after reasonable dispensing. Cosmetics have various kinds of raw materials and different properties. According to the properties and uses of cosmetics, they can be broadly divided into two categories: matrix materials and auxiliary materials. The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetics formula and plays a major role in cosmetics. The latter plays a role in shaping, stabilizing or giving color, fragrance and other characteristics of cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are made from natural, synthetic or extracted substances with different functions as raw materials by heating, stirring and emulsifying processes.
The main raw materials of cosmetics are commonly used as matrix materials and natural Additives. The general base materials for cosmetics include: oily raw materials, which are the most widely used raw materials for cosmetics, play a protective, moisturizing and softening role in skin care products, play a stereotyping and aesthetic role in the use of products; surfactants, which can reduce the surface tension of water, with decontamination, wetting, dispersion, foaming, emulsification, thickening. Other functions, known as industrial monosodium glutamate, moisturizing agents and essential ingredients for cream cosmetics, are used to prevent dry and cracked paste and keep skin moisture. Adhesives are mainly used for hair gel, mousse and gelatin mask. Powder is mainly used for making powder products, and pigments and dyestuffs are mainly used for cosmetic modification. Products; preservatives, antioxidants, in the cosmetics shelf-life and consumer use in the process of inhibiting microbial growth; perfumes, increase cosmetic fragrance, improve product value; other raw materials, including UV absorbers, dye intermediates used for dyeing black hair, perm raw materials, antiperspirant, deodorant, anti-dry skin crack Raw materials, anti acne raw materials, etc. Common natural additives are hydrolyzed gelatin, hyaluronic acid, superoxide dismutase (SOD), Royal jelly, silk fibroin, mink oil, pearls, aloe vera, malt meal stone, organic germanium, pollen, alginic acid, seabuckthorn, Chinese herbal medicine and so on.
