Q:What is the principle of ceramic membrane ?
Ceramic film, also known as the CT film. It is a kind of solid film, which was first introduced into the market by Japan's big Japanese printing company and Toyo ink company in 1996. Ceramic membrane has the high separation efficiency , stable effect, good chemical stability, acid and alkali resistance, resistance to organic solvents, bacteria resistance, high temperature resistance, anti pollution, high mechanical strength, good regeneration performance of membrane, separation process is simple, low energy consumption, operation and maintenance simple and membrane using long life and many other advantages and potential. Ceramic membrane equipment has been successfully used in food, beverage, plant (Medicine) deep processing, bio medicine, fermentation, chemical and other many fields, can be used in the process of separation, clarification, purification, concentration, sterilization, in addition to the salt. Ceramic membrane equipment can replace the centrifuge, frame and other traditional solid-liquid separation equipment, and material quality of the liquid is that traditional methods can not match, and the yield of the product is compared with the traditional method for the high.
Q:What if there is water during construction of geomembrane?
The main role of geomembrane on the road is water insulation, the part higher than the underground water level is isolated by geomembrane, and then backfill and grind, preventing the water through soil capillarity from soaking roadbed filler.
Q:Can composite geo-membrane be used for roof leaks?
No, usually we use SBS for roof waterproof. Composite geo-membrane is often used on the road and bridge projects.
Q:Why composite geo-membrane can not be used in underground garage?
Composite geo-membrane was invented in China, applied in the The South-to-north Water Diversion Project with good anti-seepage effect. While there are no composite geo-membrane in foreign countries. It has also been widely used in subway tunnel and other underground constructions. Of course, it can be used in underground garage , but you must choose the appropriate specifications. It is recommended to use 300g/1.0mm/300g composite geo-membrane. The following are the details. Composite geo membrane is geotechnical impermeable material made of plastic film as anti-seepage material and non-woven fabrics. Its waterproof performance mainly depends on the performance of plastic film. Impermeable plastic film at home and abroad are mainly polyvinyl chloride (PVC) and polyethylene (PE), which are Polymer chemistry flexible material with smaller proportion, good extensibility and high adaptability to the deformation. Corrosion resistance, low temperature resistance, good anti-frost property. The main mechanism is to block earth dam leakage passage by imperviousness of plastic film and bear hydraulic pressure and adapt to deformation of dam with greater tensile strength and elongation. Non-woven geotextile is also a kind of macromolecule staple fibre chemical material shaped through acupuncturing or hot sticking, having high tensile strength and extensibility. Combined with plastic film, it can not only increases the tensile strength and anti-puncture ability of plastic film, but also increase the friction coefficient of contact surface and make the composite geo-membrane and packaging layer stable as the non-woven fabrics surface becomes rough. At the same time, they have good corrosion resistance to bacteria and chemical action, not afraid of acid, alkali, salt erosion, high seepage coefficient.
Q:HDPE construction process of HDPE geomembrane
Clear substances that have hidden danger of puncture on bare base surface, completion and acceptance, etc. Acceptance of construction quality. ③Repair methods of damaged parts; welding form is double bead. 5. Recommendation 1, the maximum design water level. Ther is nooil pollution at joint. Planned duration is 3 days. Substances that can cause harm to anti-seepage film and constructors related to water proof materials. First, cut HDPE geomembrane into trumpet-shaped pipe sleeve according to the diameter of leachate in dam. 50×4m, do not wipe in hands. Bond is made up of asphalt latex paint, otherwise, set aside telescopic deformation caused by changes of temperature. ②Operating temperature of sweat soldering is 280 -300℃. ②Water resistance of bridge foundation. Weld after treatment. 4, Need latitudinal splicing so as not to damage the membrane surface. Dew: 5% to 8%.
Q:Why imported geomembrane (HDPE) is most frequently used impermeable material among artificial synthetic materials?
Because of its minimal permeability coefficient
Q:Which one is better, electrothermal film or electric hot plate
Electrothermal film. Electrothermal film: High resistance to pressure, aging, moisture, high toughness. shrinkage. It has stable performance, full sealing, wide range of tolerance. Its advanced technology can ensure safety and benefit human body. It has a long using period. Electrothermal film heating system is highly secure, creat no security risks. It is a very mature product. Through the test of relevant departments, it reaches national standard in terms of insulation level, pressure capacity, leakage current, flame retardant capability. User can use it with confidence. The electric heating plate is made of electric heating alloy wire and mica soft palte as heating material, coated with thin plate material for heating (aluminum plate, stainless steel plate, etc.). Its yypical applications is electric water bottles. Construct or fill in metal tubular electric heating element into aluminum dish cast in aluminum plate or aluminum plate to form aluminum plate of various shape. Typical application can be seen as rice cookers, electric irons, electric coffee pot etc..
Q:Which kind of the mobile phone screen protector is better?
There are now many kinds of film, such as high-definition film, frosted film and mirror film. If you require the beauty, I recommend the diamond film and mirror film; if you require the hand feeling, I would recommend frosted film
Q:What are the applications of geomembrane in roadbed?
Geomembrane in the roadbed is not only strengthening the subgrade, but also plays a role in the anti-seepage and anticorrosion. The geomembrane has good heat resistance and cold resistance. good chemical stability, high rigidity and toughness, good mechanical strength, environmental stress cracking resistance and tearing strength. With density is rising, the mechanical properties and barrier properties will be a corresponding increase, heat resistant, and the tensile strength is higher; It can resisit the corrosion of acid, alkali and organic solvents and others.
Q:Introduction of geomembrane
Geomembrane plastic film used as seepage-proof base material and combined with woven cloth geotechnique seepage-proofing material new material geomembrane anti-seepage property mainly depends on plastic film anti-seepage property at present at home and abroad seepage-proof application plastic film mainly include polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), tunnel practical design using ECB (blending geomembrane of ethylene-acetic acid-ethylene modified asphalt) a kind of high polymer chemistry flexible material, with small proportion, strong extensibility, high adaptability to the deformation, corrosion resistance, low temperature resistance and good anti-frost property.
