Three methods for quickly cleaning range hoods

The range hood is a good helper in the modern family kitchen, but how to clean the range hood often makes the family nervous. Here are three simple cleaning methods:

1. Pressure cooker steam flushing method. Boil the cold water in the pressure cooker. When the steam is continuously discharged, take the low-pressure valve, turn on the range hood, and aim the steam water column at the rotating blades. As high-temperature steam continuously rushes into the fan blades and other parts, oily sewage will flow into the waste oil cup along the way until there is no oil in the oil cup.

2. Soaking with detergent and vinegar. Remove the oil smoke extraction impeller and soak it in a pot of warm water for 10-20 minutes. Mix 3-5 drops of detergent and 50 ml of vinegar in the warm water.

Then scrub with a clean rag. The shell and other parts are also cleaned with this solution. This method has no damage to human skin and no corrosion to equipment, and the surface still maintains its original luster after cleaning.

3. Soap surface coating method. Make the soap into paste, and then smear it on the surface of the impeller and other devices. After the range hood is used for a period of time, remove the impeller and other devices and wipe them with a rag.

Oil stains will come off.

Wonderful method of polishing stainless steel pool

Gem identification can be divided into three aspects:

(1) The name of the gem, and determine what it is.

(2) material classification, clear material attributes.

③ Gem quality is divided into two poles.

(1) Gemstone naming. For gem identification, the name can be determined by measuring the density and refractive index data of the gem. For example, the measured gem density is 3.52 (0.0 1) g/cm 3, the refractive index is 2.4 17, and the dispersion is O.O44. Combined with its high thermal conductivity, it can be named diamond. If we also have the data of chemical composition and crystal structure of gems, the naming of gems will be more accurate and perfect. On the basis of naming gemstone minerals, the varieties are classified according to color or special light properties (cat's eye, starlight, discoloration and discoloration). For example, beryl gem minerals are divided into green beryl (also known as emerald), blue beryl is called aquamarine, and colorless beryl is called Goshenite. Beryl varieties with special optical properties include beryl cat's eye and starlight beryl. Corundum gem minerals are classified by color. Corundum with special optical properties can be used to paint star ruby, starlight sapphire and sapphire cat's eye.

(2) Material classification. Material classification and identification is one of the most difficult tasks for gem appraisers. Before naming a gem, you must answer the following questions:

Is the gem natural, synthetic or artificial?

② Has the gem been dyed and coated? Oiled or chemically treated?

③ Has the gem undergone heat treatment or color diffusion?

(4) Is the gem irradiated and colored?

⑤ Are the cracks and holes on the gem surface artificially filled?

According to the nature of materials, we divide them into two categories: precious stones and man-made products.

The gem is:

Natural gem: a substance completely formed by nature refers to a natural mineral crystal without artificial influence, which is synonymous with "purity" and "nature". Include various natural materials.

(2) Optimization of gems (artificial treatment of gems): Gems are natural substances, and the quality of gems can be improved by various new methods and means such as chemistry, heat, optics and high-energy ray radiation, so as to enhance their value. Due to the different treatment methods and strengths, it is usually difficult to draw a line between natural gemstones and treated optimized gemstones.

Workpieces are:

(1) Synthetic gemstone: The product crystallized by some artificial method under artificially controlled crystallization conditions, and its physical or chemical properties and crystal structure are basically the same as the corresponding natural gemstone. Such as synthetic diamonds, synthetic rubies and synthetic sapphires.

② Artificial stone: refers to various crystals grown artificially, which have chemical composition, physical properties and crystal structure, and have no natural reference. This artificial stone is an imitation of precious stones, such as artificial cubic alumina (ZrO2 _ 2) imitation diamond. Its hardness is higher (8.5) and its optical effect is similar to that of diamond. But its chemical composition, physical properties and crystal structure are different from a natural diamond, and there is no natural comparison. It can only be called artificial stone, not "synthetic gem".

(3) Assembled stone (also called assembled stone): Assembled stone refers to two or more crystalline or amorphous substances that are combined into products by unnatural methods through adhesives or other means, and its components can be divided into gems, other minerals and chemicals. Split stones entering the market: emerald split stones, ruby split stones, etc.

(4) Imitation: using various materials: chemistry, plastic, glass, artificial crystal, etc. Imitate the effect, appearance or color of natural and synthetic gems, without their chemical properties, physical properties and crystal structure. There are both gemstone imitations and artificial gem imitations.

⑤ Recycled products: The raw materials of precious stones are melted, bonded or fused into an integrated artificial product.

At present, all kinds of artificial products flock to the market one after another, and the task of gem mineralogist is quite heavy to identify all kinds of artificial products to ensure the acquisition of real gems.

(3) Quality classification of gems. Gemstones are classified into three categories: diamond, colored gems and jade. At present, the principles and methods of grading and the quality grading standards of diamonds are relatively perfect, but the quality grading standards of colored gems and jade have not been universally recognized and unified as 4C standards of diamonds at home and abroad. Diamonds are generally classified by 4C classification standards in the world, namely, weight, color, clarity and cut. China has formulated a national standard for diamond classification, and in principle, it adopts 4C standard. However, it should be noted that people have different tendencies in understanding and mastering 4C standards in different periods, that is, they will pay different attention to 4C. At first, people emphasized the weight and thought that the bigger the diamond, the more valuable it was. Later, it was found that not all big diamonds were of good quality, so they developed to pursue high color grade, the highest clarity, glittering and translucent, and became more precious and rich. What's the next point? People will wait and see! Now it is suggested that the most perfect diamond comes from exquisite cutting. The position of the cutter may rise.

Jewellery circles all over the world are studying to establish a quality grading system for colored gems and jade. It is proposed that the quality grading standards of colored gems and jade should be gradually established and improved on the basis of 4C standard of diamond quality grading, which is a problem that everyone is concerned about at present.
