Which kind of computer anti-reflective screen film is better?
- Fashionable IT computer screen protective film has both the type which doesn't prevent scratching and light reflection resistance film. They all have high definition and high light transmittance with light transmittance of more than 95%. Electrostatic adsorption, does not contain glue, automatic attachment, convenient to stick. dedicated model, no need to cut, size precision of 0.01MM, perfect fit. filtering and brightening, filter 10% redundant glare, comfortable vision. Blocking 90% radiation and ultraviolet rays, so as to protect the eyes. Dust-proof, water-proof, oil-proof, fingerprint-proof, clean with water before using if necessary.s

How to stick digital plate film ?
- As long as the activity area of patch, somewhere else stick not so-called, in fact not the film board with no matter, I use the cth-670 should be no film (buy back what is what, in fact there are scratches) no matter ah, anyway is not display, and not to look. Flower flower.s
Concrete engineering quality defects how to deal with?
- Phenomenon 1: Local lack of concrete surface rough paste, or a small pit, no exposed steel reinforcements. The reason: 1) template surface roughening or cleaning is not clean; 2) release agent brushing uneven or local leak brush; 3) the template joints loose stitching, slit pouring concrete slurry leakage. 4) vibration is not dense, concrete air bubbles remain in the bubble does not discharge a portion of the template surface. Patching scenarios: After the concrete surface well watered wet mortar with concrete grade will Pock smooth pressure light, the color is consistent. After the repair within 12 hours, water moisture conservation. Low partial concrete strength part, immediately remove and re-organize staff reinforced adjustment, formwork and pouring concrete, the template before pouring water wet. 2 phenomenon: A cavity within the concrete structure, no concrete local or cellular particularly large. The reason: 1) In the densely reinforced or reserved holes and embedded parts at the concrete pouring is not smooth; 2) out of order and construction technology construction serious operation, resulting in leakage vibration; 3) segregation of concrete, mortar separation, Dan Zicheng heap, or run pulp; 4) a cutting excessive vibration is not in place. Patching scenarios: The concrete around the loose and weak serous chiseled, rinse with water pressure, support is provided with trays template, moist after watering, a concrete structure with a high specific strength grade Semi hard fine stone concrete pouring carefully layered, powerful tamping, and conservation. Outstanding concrete structure surface, to be the strength of 50% and then chipped away, the surface with a 1: 2 cement mortar smooths
What are the impermeable advantages of comosite geomembrane?
- composite geo-membrane is combined by geotextile and geomembrane, permeable material is mainly used in seepage-proof, the products have high extensibility and deformation, modulus, acid and alkali resistance, corrosion and chemical resistance, seepage-proof and other features.s
How to construct and weld hdpe high density polyethylene sheet material?
- Start motor. 9mm × 0. Welding can't be done under the condition of large sand. Set temperature. Peel on the scene. Welding is in progress. Use welding rod that has the same quality as raw material. Under the condition that geomembrane length is not enough: Adjust the pressure and need atitudinal joint. When HDPE geomembrane is paved, taking protective measures is exceptional according to the temperature change in the lacal area and performance requirements of HDPE geomembrane. The welding machine is used in the welding of HDPE seepage-proof film. 3mm sample is needed during the welding of heat carve welder. 3. Dew should use squeezing-mode hot melting welding machine. Whether HDPE is what you said HDPE high density polyethylene board material. Pay attention to the operation condition of welding machine at any time. When the welding is started every day, use dual-track sweat soldering. 9. Beauty. Dart is not allowed to appear during the welding of film. Set speed://dlyamaxun.com/ shear test, set aside telescopic deformation resulting from the changes of temperature, do not cross. After the sample is qualified, temperature is lower than 5℃. 4. During the raining days or under the condition that humidity, dust and pressure exist at seam, welding line requires tidiness and lap joint check of welding line. 1. Moisture condensation. Oil pollution is not allowed at seam. The voltage stabilizer must be used. The test weld should be done on the scene, then re-weld with stitching in longitudinal direction. Sundries like sediment are not allowed in the lapping section of HDPE seepage-proof film. Use the speed that is adjusted before. Under special circumstances, when local electricity is used and sundries exist, clear before welding://dlyamaxun. The welding process of heat carve welder is divided into. The following is the construction welding of HDPE seepage-proof film. 2.7s
Does seepage-proof membrane belong to geomembrane?
- Geomembranes are widely used for their excellent seepage-proof performance measured by order of magnitude of 1*10*-13. The basic function of which is cultivation. The seepage-proof performance is good, but you'd better choose environmental ones with GBT17642-1998, GBT17643-2008 as well as other specifications and standards as reference.s
What are the benefits of the water film floor?
- 1, the mill floor brick table light treatment brightness reached more than 70, to achieve the quality of marble dust slip. 2, the mill floor tile surface hardness can reach 6-8 level, close to the surface of granite with high hardness, good abrasion resistance. 3, terrazzo floor tile can optionally spliced color, color can be custom made. 4, water floor brick cracks, not afraid, not afraid of heavy vehicles rolled heavy drag, not contraction deformation. 5, terrazzo floor brick does not dust, and has high cleanness. 6, the mill floor brick not burning, not firing, aging resistance, fouling, corrosion resistance, no smell and no pollution. 7, terrazzo floor brick bright finish, if need to improve the light hit the ordinary floor wax (does not affect the anti-static performance). 8, terrazzo floor brick decoration case of horizontal and vertical dividing strip without clearance, connection density, the overall appearance is good. 9, water floor brick building performance and mechanical properties and all kinds of construction quality of terrazzo floor is complying with the requirements of GB50209-2002, to meet the requirements of JC507-1993 standard building terrazzo.s
