Gas heating boilers Maintenance brief (two) to share with you a small series of measures dry gas heating boiler maintenance, then share with you another maintenance measures that the maintenance of the wet method. Three wet maintenance method: (1) After heating boiler shutdown, we must first produced during the operation dirt clearing is completed, in the process should have a tubing connections with the outside world were cut block. (2) the internal heating boiler filled with demineralized water, avoid incorporation of air, in the process, should be carefully monitored to ensure no leakage of boiler. (3) filled with the gas heating boiler, an alkaline solution, the surface of the metal protective layer produced alkaline, boiler avoid corrosion phenomena. The above are some commonly used method of wet maintenance of boilers, of course, you may also have better ways, who will need to be different debugging, and choose a more appropriate and reasonable ways and means depending on the situation. In short, boiler maintenance shutdown of the boiler is the process of using a more important part to ensure that the boiler can always be safe and stable up and running.
Routine inspection of boiler energy saving way to check the boiler energy saving boiler is the most basic test. First, the overall boiler internal and external conduct a basic test. Routine testing basic skills boiler inspection, but the requirements of inspectors is higher, boiler inspectors are testing has a wealth of experience and high analytical skills. Hot water boiler steam energy saving Appearance test: First, to test boiler body, particularly the structure of the respective pressure element is reasonable, the pressure receiving surface and the metal member welded seams if there are defects, such as the presence or absence of corrosion, wear, there since no cracks or groove deformation, bracing and without fracture connecting seam, weld surface defect status. Found cracked test suspicious, but they can not only distinguish visually confirmed, can then use a solution of nitric acid concentration of 10% of the suspicious areas wiped clean, and then carefully observed with a magnifying glass to determine whether a crack . If the above test when the steel sheet has adhered dirt scale, a hammer tip may be used to test scale, rust knock, carefully tested after wiping. Energy saving hot water boiler steam hammer test: test hammer holding of local boiler pressure parts need to be inspected tap the appropriate strength, as well as the eyes and ears with hands, which is a comprehensive visual auditory tactile feel there are three kinds of senses to judge defect-free test. Our inspectors can properly grasp this method can be done to determine the correct level. It also reflects our boiler inspectors have a very solid basic skills. Two hammer test is not the same, are flat and round tip, the handle is made of rigid material, we have a special shape narrow neck, an elastic characteristic of the use of the handle to enhance the feel for easy inspection.
At the same time, we remind you that when choosing a gas boiler manufacturers, need to give consideration to the following four aspects: 1, seniority long, very mature technology and system manufacturers; 2, in the old users and good reputation of the manufacturer; 3, boiler cost-effective, long life and stable manufacturers; 4, regardless of pre-sale or service quality are guaranteed manufacturers.
Xiamen Rui Yi Hotel is available straight left Gulangyu the most beautiful views of the BRIC countries delegations designated top hotels, the best location in the heart of Xiamen, modern trends and classic style pavilions. The hotel features well-appointed room service, fashion and superior restaurant, bar, meeting rooms and a gym, swimming pool and other recreational facilities, people feel contented and comfortable. Projects and programs as Xiamen Rui Yi Hotel Xiamen City landmark hotel building, attaches great importance to environmental protection philosophy, which party fast boiler manufacturing philosophy coincide. In late 2016, the two sides signed an electric steam boiler for sodium metasilicate processs for hotel supplies disinfection work, since the electric steam boiler, any security incidents never happened, Rui Yi Hotel ensure normal operation.

Sodium metasilicate is produced by the fusion of sodium carbonate with silicon dioxide or silica sand at about 1400 °C. It is commercially available in various grades and in both the anhydrous and pentahydrate forms from several U.S. companies. Annual capacities range from 50 to 806 million pounds.Online chat
1.Citric acid and ammoniated citric acid. Citric acid is a weak, tri-basic, organic acid. It forms complexes with ironII, IronIII and CuII ions which are stable in solution over a wide pH range. When a citric acid solution is made up to a concentration of 3 to5 %, its pH is between 2 and 3, i.e. it is only weakly dissociated.Online chat
Introduction. The term sodium silicate refers to any one of several compounds containing sodium oxide, Na 2 O, and silica, Si 2 O, or a mixture of sodium silicates. Sodium orthosilicate is Na 4 SiO 4 (or 2Na 2 O·SiO 2); sodium metasilicate is Na 2 SiO 3 (or Na 2 O·SiO 2); sodium disilicate is Na 2 Si 2 O 5 (or Na 2 O·2SiO 2); sodium tetrasilicate is Na 2 Si 4 O 9 (or Na 2 O·4SiO 2).Online chat
PQ sodium metasilicate products like METSO BEADS® 2048 have a definite crystalline form and a SiO 2 to Na 2O ratio on a molar basis of 1:1. They are readily soluble in either hot or cold water and form solutions that are not as viscous or tacky as those made with other, higher-ratio silicates. The pH levels of sodium metasilicateOnline chat
Sodium silicate is obtained by mixing raw materials at first into a dissolution vessel and then into a reactor in which the reaction between siliceous sand and sodium, hydroxide occurs. Reactor is heated by saturated steam and works under pressure. When the reaction time is spent the batch is transferred into a vessel and then filtered.Online chat
Bring purified water to a low simmer (approximately 175 degrees) on an electric stove. Stir sodium silicate powder into hot water with a long-handled metal spoon. Continue stirring until the powder is completely dissolved. Remove solution from heat and allow it to cool to room temperature.Online chat
Jan 20, 2017 · Manufacture: Quartz sand and alkali are reacted in either the liquid or solid phase to produce water glass. Sodium carbonate or caustic soda are common alkaline materials used in the process. Water Glass Uses. Water glass is used to make silica gel beads or packets, which are used to protect clothing and electronics from moisture.Online chat
Sodium silicate Wikipedia. 2019-6-10 · Sodium silicate is a generic name for chemical compounds with the formula Na 2xSiO 2+x or (Na 2O) x·SiO 2, such as sodium metasilicate Na 2SiO 3, sodium orthosilicate Na 4SiO 4, and sodium pyrosilicate Na 6Si 2O 7. The anions are often polymeric.Online chat
Sodium Metasilicate. Sodium silicate has been successfully used as a chemical grouting material for many years. It is used in particular during the drilling of very permeable formations (Xiang 2007). When an aqueous mixture of sodium silicate and an activating agent, such as an ester, is injected into the ground, the silicate solution reacts to form a colloid, which polymerizes further to form a gel.Online chat
Apr 24, 2017 · Automotive Uses. Elevated temperature is the key to sodium metasilicate's usefulness in automotive applications.
