Borosilicate glass mainly refers to toughened (tempered) borosilicate glass. It is a type of glass whose main components are SiO 2   and B 2 O 2 . It has high working temperature, considerable thermal shock resistance and excellent resistance to chemical attacks. Buy All Type  Gauge Glass  From Aohong Special Glass Manufacturing Co,.Ltd. Borosilicate glass has a very low coefficient of thermal expansion, which can withstand high thermal shock, and the glass surface changes very little with temperature. It is the first choice for precision instruments. Borosilicate sight glass contains few ferrous ions and has no obvious absorption in the visible spectral region, so it appears clear, transparent and colorless. It can be used as an observation window for effective and intuitive observation, so it is widely used. Borosilicate sight glass can be processed into flat (such as round, square, special-shaped) glass, and it can also be processed into tubular glass. The flat gl...

Despite its small size, a boiler’s sight glass has big importance. In this post we’ll cover how to replace an old or malfunctioning sight glass so you can keep your boilers working and your workplace safe.  It’s important to note that different types of glass and different lengths of glass will provide you with different readings. Always make sure that the glass you’re using is rated for your boiler. Now let’s get started! NO PRESSURE Check to make sure the shut-off valves are tightly closed, or make sure your boiler is completely empty of pressure and water. Be positive that there is no pressure in the line before replacing your sight glass, or you risk serious injury. In our sight glass replacement demonstration video, we use a boiler that is not firing or hooked in.  DOWN THE DRAIN Once you’re positive the line has no pressure, valve the water column off, and drain the water from the gauge through a valve at the bottom. Remove the protective rods, crack the nuts on the...

  As a   Fused Quartz Glass Supplier , share it with you. Quartz Glass After the instrument has been used for a period of time, it will appear to be dusty. The dust on the machine will cause a large error in the instrument, and it may also lead to a failure of the test. Therefore, the instrument must be clean and punctual in the process of use, so as to ensure the normal use of the instrument. Today, I will introduce us to the cleaning methods of quartz glass instruments and meters, and hope that these cleaning methods can help us. Quartz glass instrumentation Quartz glass instrumentation cleaning. Never use strong alkali to clean, because strong alkali will corrode the polished cuvette. It can only be soaked in lotion or 1% to 2% detergent, and then rinsed with tap water. At this time, use a small stick or cotton swab wrapped in silk cloth to rinse. The effect will be very good. Clean and clean the cuvette No water droplets hang on the inner and outer walls. The glass and pla...

As a   Glass Lab Manufacturer , share with you. Coating is to coat a very thin transparent film on the surface to reduce light emission. There are many production methods for coated glass, mainly including vacuum magnetron sputtering method, vacuum evaporation method, chemical vapor deposition method and sol-gel method. Optical Glass Blanks 1. Magnetron sputtering coated glass can design and manufacture multi-layer complex film system by using magnetron sputtering technology, which can plate a variety of colors on the white glass substrate. The film has good corrosion resistance and wear resistance, which is suitable for production. And one of the more used products. 2. There is a certain gap between the variety and quality of vacuum evaporation coated glass and magnetron sputtering coated glass, which has been gradually replaced by vacuum sputtering. 3. The chemical vapor deposition method is to introduce reaction gas into the float glass production line to decompose on the hot gl...

  As a   Level Gauge Glass Manufacturer , I would like to share with you. Routine inspection of level gauge and troubleshooting methods, suitable for magnetic flap level gauge, two-color quartz tube level gauge, glass tube level gauge, etc. 1. First check whether the power supply is connected correctly. If the connection method is found to be incorrect, modify it according to the operation manual. 2. Use a three-voltmeter to measure the voltage between +24V and O/P. The voltage should be between 13V and 36V. If the voltage is abnormal, check whether the circuit or related equipment is abnormal. 3. The second item should be confirmed to be normal, and then a milliamp meter should be connected to the 4~20MA circuit to check whether the current is normal. If the current value is abnormal, replace it with a new product or contact customer service personnel. Transparent Level Gauge 4. Use a voltmeter to check the voltage between IN and COM. Normally, it should be about 2.5V. If the...
