Can you tell us more about that?

A chemical sink is a piece of equipment used in a laboratory to store and dispose of chemicals. Its main functions are as follows: Storing chemicals:

Laboratories often need to store large quantities of chemicals, such as acids, alkalis, organic solvents, and more. These chemicals can have dangerous properties such as corrosive, toxic, or flammable, so they need to be kept in a chemical sink to be safe. Disposal of Waste Liquids:

The actual or annihilation operation will produce a variety of waste liquids, such as dilute acids, dilute alkalis, organic solvents, etc., which contain dangerous substances and cannot be directly discharged into the sewer or natural ring key flush. The chemical sink can be connected to a special drainage system to remove the waste liquid and dispose of it in a uniform manner. Washing utensils:

During the experiment, various experimental utensils need to be used, and they need to be cleaned in time after use. Chemical sinks can be used to wash, disinfect and wash utensils to ensure they are clean, hygienic and residue-free. Protective measures:

During the experimental operation, some chemicals may splash out, or leak out. Chemical water tanks can be used as a protective measure to prevent chemicals from splashing on the experimenter, ensuring the safety of the experiment. In conclusion, chemical sinks are important in the laboratory and can be used to store a variety of chemicals, dispose of waste, wash utensils, and provide protective measures to ensure the safety and science of experimental operations.

Uses of chemical sinks:

A chemical tank is a container used to store water, which is often used in conjunction with a laughing gas cylinder to collect gases by drainage. Glass tanks are often circular in shape, and because of their transparency, they are easy to observe when collecting gas by drainage.

Precautions for chemical sinks:

1. The chemical sink cannot be heated, nor can it hold hot water that is too hot.

2. When collecting gas, the chemical tank can choose different liquids according to the nature of the gas. For example, chlorine can be collected by draining saturated brine.

3. If stearic acid is used as the main raw material to determine the constant of Avogadero by single-molecule membrane method, it is advisable to use a more regular glass sink instead of plastic water tank.

Pro, mercury oxide because mercury + oxygen - (heating) - mercury oxide glass finger bell cover is equivalent to a gas collection cylinder, mercury tank is equivalent to a sink in the laboratory, and the water tank is mainly used to collect gas by drainage. Because the material of the sink is made of glass and plastic, there are two types of sinks: glass sinks and plastic sinks. When using the glass sink, take care of it and do not touch it on a hard iron utensil.

Plastic sinks, on the other hand, should be kept away from fire.

Summary. Pro, the sink is an instrument used to collect gas by draining water or used to hold a large amount of water and can be used to wash dishes and food, and its main material is stainless steel. In addition to stainless steel, there are also iron enamels, ceramics, etc.

What is a sink and what are the classifications of sinks.

Pro, Wuchang sink is used for drainage method to collect gas regret inspection body or used to hold a large amount of water and can be used to wash tableware, food instruments, its main material is stainless steel. In addition to stainless steel, there are also iron enamels, ceramics, etc.

It is divided into single pot, double pot, large and small double pot, special-shaped double pot, three pots, etc.

Stainless steel water type good groove: acid and alkali resistance, oxidation resistance, beautiful surface, can often keep bright as new, durable. The stainless steel sink with a thickness of the lead is strong and elastic, resistant to impact and abrasion, and does not damage the utensils to be cleaned.

It can develop a variety of functions, lightweight, and can be made into different shapes and styles through precision processing, which can be matched with all kinds of different kitchen countertops.

Ceramic sink: beautiful appearance, fashionable Songchai high-end, the white color of the coarse cherry key gives people a clean feeling, resistant to high temperatures, and inexpensive. However, its shortcomings are also obvious, with fewer styles, monotonous colors, and lack of luminosity; The water absorption rate is low, if the water penetrates into the ceramic, it will produce expansion and deformation;

1. The sink is used to drain water, collect gas, and can also be used to hold a large amount of water and wash tableware and food.

2. There are many types of sinks on the market, which are divided according to the material, such as stainless steel sinks, iron enamels, ceramics, etc.

3. Because stainless steel is not easy to rust and has stable performance in all aspects, it is also widely used.

Classification on the structure of the sink.

1. Single basin type, 2. Double basin type, 3. Triple basin type, 4. Wing type.

The single-basin sink basin is large, which is more convenient and comfortable to choose, and there are long basin types with a length of more than 900mm on the market. The shape is also more luxurious, of course, ** is also more expensive. The double basin type is the most practical, generally for the mother and son double basin, that is, a main basin and an auxiliary basin body, the main basin is washed, and the auxiliary basin is used for clean foam.

The division of labor between the three basins is more clear, and its disadvantage is that the basin is large, and the large kitchen can be useful. Tanks with airfoils are not very popular in the domestic market, but they are more popular in Europe and the United States.

Single slot double slot. Three troughs with drain plates.

High and low sink sinks are classified by material.

Sinks can be divided into cast iron enamel, ceramics, stainless steel, artificial stone, steel plate enamel, acrylic, crystalline stone and other varieties, among which stainless steel, artificial stone, granite (quartz) these four are more common.

Stainless steel: Stainless steel sinks are the most widely used, and their metallic texture can better integrate into the overall style of the kitchen. There are many types of stainless steel, among which the most suitable for making sinks is European 304 stainless steel, which is corrosion-resistant, oxidation-resistant, tough, strong and durable.

Granite: Granite (quartz) sink is made of the hardest high-purity quartz material in granite (quartz) mixed with food-grade high-performance resin, and is die-cast at high temperature by high-tech technology. The granite sink can effectively eliminate scratches and dirt, and can withstand temperatures of up to 300 degrees Celsius without fading.

The raw materials of the sink are environmentally friendly, non-toxic and radiation-free.

Artificial stone: Artificial stone is often used in the countertop of cabinets, it is rich in color and can be matched with many styles of cabinets. It's just that the texture is not as hard as stainless steel, so avoid bumping knives or hard objects when using it to prevent scratching the surface or destroying the finish.

Artificial stone sinks need to be gently wiped off with a cloth after each use, and if they are not cleaned for a long time, it is easy to cause stubborn stains.

Generally speaking, stainless steel sinks are durable, wear-resistant, moderate, cost-effective, and are the most widely used sinks. Stainless steel sinks are best to use cold drawing process, which can ensure that the internal physical structure of the steel is not damaged, maintain the original corrosion resistance, the bottom of the basin does not need to be coated, tough and durable, and often used and new.
