On August 13, in Europe, the birthplace of household heating, condensing gas heating water heaters have won the majority of European consumption due to their ultra-high efficiency, excellent technology, strong fuel utilization and latent heat recovery capacity The trust of the people has become the mainstream product. With the development of global synchronization technology, more and more consumers in China are experiencing an unprecedented and efficient experience brought by condensing gas heating water heaters. In order to repay consumers' trust in Bosch products, from now on, Bosch, an excellent supplier in the global HVAC industry, will provide each condensing gas heating water heater user with a free three-year annual inspection and maintenance service.
Why do annual inspections and maintenance for condensing gas heating water heaters? Just like buying a car requires regular maintenance, gas heating water heater products, especially condensing gas heating water heaters also need maintenance. In Europe, the annual inspection of gas-fired heating water heaters has continued for many years as a mandatory policy. In addition to being able to clearly understand the working state of the condensing gas heating water heater, the annual inspection can also extend the service life of the condensing gas heating water heater through maintenance, maintain thermal efficiency, and help you create a safe and comfortable heating space and achieve continuous energy saving Environmental protection purpose. Not only that, through regular professional inspections and professional maintenance, it can also ensure the continuous efficient and stable operation of condensing gas heating water heaters, avoiding the reduction of thermal efficiency and the generation of scale, and can also avoid the safety problems of condensate corrosion.
The free annual inspection and maintenance project of the condensing gas heating water heater introduced by Bosch this time will conduct a comprehensive and detailed inspection of the water system, combustion system and combustion air-fuel ratio of the condensing gas heating water heater to help the condensing gas Users of heating water heaters develop good habits to create a safe and comfortable heating environment. At the same time, Bosch recommends that users sign an annual inspection agreement with Bosch certified after-sales service partners after the free maintenance period to ensure the long-term healthy use of the product.

Pe Plastic Sheet, full name is Polyethylene Sheet.
Physical properties: PE plastic Sheet is the most simple structure of the macromolecular organic compounds, the world's most widely used polymer materials, composed of ethylene polymerization, depending on the density is divided into high density polyethylene, medium density polyethylene and low density polyethylene.
(1) LDPE Sheet
Low density polyethylene Sheet (also known as high pressure polyethylene Sheet)
(2) LLDPE Sheet
Linear low density polyethylene
(3) MDPE Sheet
Medium density polyethylene
(4) HDPE Sheet
High density polyethylene (also known as low pressure polyethylene)
(5) UHMWPE Sheet
Ultra high molecular weight polyethylene(6)Modified polyethylene sheet
Chlorinated polyethylene (CPE) and crosslinked polyethylene (PEX)
(7)Ethylene - ethylene copolymer
Ethylene/propylene copolymer (plastic), EVA, ethylene, ethylene butene copolymer - other olefins, such as octene POE, cyclic olefin copolymer, ethylene/unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH).
Polyethylene, which has a molecular weight of 3 million to 6 million, is known as UHMWPE.
Ultra high molecular weight polyethylene is very strong and can be used for body armor.
1. Papermaking industry: suction box board, scraper, molding plate, bearing, gear;
2. Mining industry: charging barrel, abrasive and adhesive-resistant back lining for warehouses;
3. Chemical industry: acid pump, filter plate, worm gear, bearing;
4. Food industry: packing machinery parts, bottle guide, screw, wear plate, slide way, stud weld, roller and other transmission parts;
5. Textile industry:buffer board;
6. Food processing industry: chopping block, refrigerating plant;
7. Wharf: anti-collision board.
1. Acid and alkali resistance, resistance to organic solvents
2. Excellent electrical insulation and static resistance
3, Can still maintain a certain touness even at low temperature
4. Extremely high impact strength
5. Low friction coefficient
6. Non-toxic
7. Low water absorption
8.Lower density than any other thermoplastic plastics (<1g/cm3)
Disadvantages:
PE Plastic sheet have Weak mechanical property, air permeability, easy deformation, easy ageing, brittle, brittle less than PP, easy stress cracking, surface hardness, easy to scratch.
Difficult to print, in printing, surface discharge treatment, cannot electroplating, the surface has no luster.
Specification: the diameter of the PE rod can be produced from 2mm to 250mm. The conventional length is 1000mm, and the length is unlimited.
The thickness of PE sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of10-180mm is 600*1200mm.PE sheet can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited
Color: natural color is wax white, also can be customized black and color, the order of the color to order is 500KG.
Add antistatic agent to the permanent antistatic electric bar, and the volume resistance value is between 6 to 9 power of 10.Add flame retardant to the flame retardant rod from UL 94V-0 to HB flame retardant grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.
Combustion characteristics:
Combustion situation: easyCombustion flame status: molten drop, yellow lower blue
After the fire: continue to bur
Smell: the smell of wax burning
Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
