Various Laboratory Products Bring Many Benefits In Our Life

There are kinds of Laboratory products we know, such as Flasks, Burettes, Beaker, Test Tubes, Alumina crucible, Glass Bottles and so on. They play an important role in the Laboratory, with the development of Chemistry, our life will be more and more nice. Laboratory products are widely used in the chemistry lab. For example, Laboratory Porcelain has already used for Tooth. Glass Bottles used for storage.
 Laboratory Porcelain
There no big difference between porcelain and Zirconia ceramic crowns for teeth. Both effectively satisfy patients' aesthetic considerations because the material can be chosen carefully so that it matches the color and shade of any existing natural teeth. It is strong enough to support force and load and when it is reinforced by a metal of zirconium core, it is given even better strength to perfect function to the mouth of patients.

Glass Bottles: Bottles are common glassware used in a laboratory. A Glass Bottle provides adequate, long term storage solution for harmful and toxic gases.

When it comes to selecting the right kind of Laboratory Glassware, a number of things should be kept in mind. For instance, it should be resistant to thermal shock, should have high chemical potency and must withstand high temperature. Laboratory Glassware has a lower alkalinity and this attribute makes it much more durable and long-lasting.

There are one product we most familiar is the flask. Flasks have a narrow-neck entry. They can be conical, spherical or cylindrical in shape. These are used to heat substances on a wire gauge. Flasks are one of the most important Scientific Laboratory Glassware.

High Quality Porcelain Insulators Supply With Best Materials

CS Ceramic CO.,LTD produce high quality products for high voltage and railway electricity networks. Porcelain Insulator is one of the main products of our company, we have our own factories in china, the best quality materials for the best products. And the many products can be customized by the different needs.
  Porcelain Insulator
Porcelain Insulator
Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation. The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmission towers. They support the weight of the suspended wires without allowing the current to flow through the tower to ground.

Our insulators for transmission lines are produced in accordance with international standards and the respective customer specification for applications in the area of energy distribution and transmission in mechanical classes up to 400 KN tensile forces. In addition, we also design entire insulator chains from long rods. To improve the outer layer properties our products are also available with silicone coating.

Electrical ceramic insulators are the absence of electrical conduction. Electronic band theory (a branch of physics) says that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal. If no such states are available, the material is an insulator.

Older dry process insulators were sometimes embossed. Like with glass insulators, markings were engraved into the mold, and when pressed the letters would be raised on the insulator surface. A number of earlier Ohio Brass styles are also embossed.

Under glaze ink marked insulators are stamped with an ink pad prior to glazing. The glaze does not hide the mark completely, and so a permanent identification is made. This method is commonly used at present.

There are also many different materials of the high quality porcelain insulators available in our factory, welcome to visit and the best services for you!

The Features About Zirconia Oxide Ceramics And Full Ceramic Bearing

Full ceramic bearing could be used in following industries: chemical, semi-conductor, valve & pump, food, electronic, medical, vacuum, refining, insulation, etc. Compared with traditional metal bearing, full ceramic bearing have some excellences details at below.
 full ceramic bearing
Zirconia Oxide Ceramics could be used at higher temperature. Ceramic maintains mechanical properties at high temperature, so full ceramic bearing can be used at elevated temperature. Full ceramic bearing are more suitable for chemical industry application. Zirconia Ceramics are more suitable for temperature-variation application. Because thermal expansion co-efficiency of ceramic are smaller than metal, so the change of clearance of full ceramic bearing is smaller than that of metal bearing. And it has more resistance to seizing due to smaller thermal expansion. Full ceramic bearing could work under poor lubrication, because ceramics are self-lubrication. Full ceramic bearing could be used at high-vacuum environment. Zirconia Oxide Ceramics could be used as insulation bearing and can prevent Electrical Arcing because ceramics is not electrical conductor.
Zirconia Ceramics

Pure zirconia exists in three crystal phases at different temperatures. At very high temperatures (>2370°C) the material has a cubic structure. At intermediate temperatures (1170 to 2370°C) it has a tetragonal structure. At low temperatures (below 1170°C) the material transforms to the monoclinic structure. The transformation from tetragonal to monoclinic is rapid and is accompanied by a 3 to 5 percent volume increase that causes extensive cracking in the material.

Zirconia is an extremely refractory material. It offers chemical and corrosion inertness to temperatures well above the melting point of alumina. Zirconia Oxide Ceramics could be used in magnetic environment because ceramics do not respond to magnetic forces. The material has low thermal conductivity. It is electrically conductive above 600°C and is used in oxygen sensor cells and as the susceptor (heater) in high temperature induction furnaces. With the attachment of platinum leads, nernst glowers used in spectrometers can be made as a light emitting filament which operates in air.

Know About The Chemical Properties Of Magnesia Cupel

 
Know About The Chemical Properties Of Magnesia Cupel


Do you know about the use of magnesia cupel? If you are interested in the experiment, I'll tell you some things about it. The features of our new products- High purity Magnesia cupel: High temperature, good thermal conductivity, corrosion resistance, high melting purity, long life.
 
magnesia cupel

An experiment of grey blow:
The magnesia cupel placed in a muffle furnace, close the door at 900-1000 ºC 15-20 minutes to remove the volatile matter and organic matter, will lead buckle into the magnesia cupel ash blowing. When the molten lead all peeling, slightly open, temperature should be controlled (not less than 800 ºC in order to avoid the occurrence of lead oxide coagulation) at 800-850 ºC. When the lead oxide is absorbed by all the magnesia cupel, there's a flash of gold and silver alloy grain immediately, quickly remove the magnesia cupel to cool. Remove the gold particles; small hammer flat the next step to be determined procedures.

Magnesia cupel is absorbed lead oxide (or bismuth oxide) porous refractory vessel with ash blowing lead button (or bismuth buckle) when. There are three common magnesia cupels: cement gray dish, ashes - and magnesia cement gray magnesia cupel dish.
 magnesia cupel ash blowing
① Cement dust pan with 400,500 No. of portland cement, plus 8 to 12% of water, mix, pressed on gray dish machine. Portland cement composition contains CaO60 ~ 70%, A1 2O3 4 ~ 7%, SiO2 l9 ~ 24%, Fe2O3 2 ~ 6%. Cement is inexpensive common materials. Cement gray dish hard, not easy to crack, but the precious metal after the loss of two larger than when the ash blowing.

② Magnesia cupel and ashes - cement dust pan with sheep bones burning ashes, ground, and then get burned, including organics must all be removed. Its composition was 90% calcium, 5.65% calcium oxide, 1% magnesium oxide, 3.1% calcium fluoride. Fineness of ashes is less than 0.147mm, 0.088mm which should account for more than 50%. Made with pure ashes loose magnesia cupel can be used for coarse gold, crude gold ash blowing. Assay analysis generally mixed magnesia cupel ashes and cement, ashes and cement mix in different proportions, plus 8 to 12% water, dish machine in the gray repression. Different people do different test results, some believe 3: 7 Well, there are believed to be four: 6 or 5: 5 good. Ashes - harder than pure cement gray ashes magnesia cupel dish, but, more than cement gray fluffy dish. With ashes - cement gray magnesia cupel to blow, the loss of gold, silver dish smaller than the gray cement. Preparation of the ashes of more trouble to go through burning, ground several procedures to be made.

③ The calcined magnesia cupel ground, require more than 63% by 0.074mm sieve of 0.2 ~ 0.1mm particles does not exceed 20%. End of magnesia to pressure in the ground after a few days, or else have to place long after agglomeration. Take 85 parts and 15 parts of finely ground magnesite No. 500 cement, mix, add 8 to 12% water pressure made ​​the dish. When the blow with the loss of precious metals made ​​magnesia gray magnesia cupel is smaller than the first two.

How to use crucibles in an correct way



How to use crucibles in an correct way


CS Ceramic CO.,LTD has a catalog that covers a series of carbon &sulfur crucibles, Infrared carbon Sulfur Analyzer Crucibles,Alumina Crucibles,Zirconia (zirconium oxide) ceramic ,labware Ceramic Crucible ,stonewares, wolfram and tin-assisted flux and has a total number of commodities of over one thousand.



As we all know, there are kinds of different types of Alumina Crucible, and the applicability and attention of using are different as well. Now, I'll tell you how to use crucible in an correct way.

 Carbon Sulfur Crucibles

Carbon Sulfur Crucibles is a deep bottom bowl ceramic container. When you want to fire solid when heated, it is necessary to use a crucible. Because it is better able to withstand high temperatures than glassware. The crucible using a crucible cover will usually inclined on the crucible was heated to prevent jumping out, and to allow air to pass in and out of the oxidation reaction may be carried out.

Because the bottom of the crucible is small, generally need to stand in the mud on the triangle directly heated by fire. Crucible being put to use in the iron triangle rack or diagonal can be, depending on the needs of the experiment can be placed on their own. After heating the crucible can not immediately be placed on a cold metal table to avoid it because of the rapid cooling and rupture. Neither shall immediately placed on a wooden table in order to avoid scorch your desktop or cause a fire. The correct approach for the indwelling natural cooling rack in the Iron Triangle, or on the Internet so that it slowly cooled asbestos. Please refer to access the crucible tongs.

The purposes of Alumina Crucibles are evaporation of the solution, concentration or crystallization and burning solid matter. There are some caution of using crucible, it can be directly heated, heat is not quenched, remove the crucible tongs, when use crucible, it should heated in a technica shelves. To stir when evaporation; evaporated by heat when nearly evaporated.
