Hydroxypropyl methyl cellulose is a kind of non-ionic cellulose ether which is made from natural macromolecular material cellulose through a series of chemical processing. They are a white powder that swells into a clear or slightly turbid colloidal solution in cold water. It has the characteristics of thickening, adhesion, dispersion, emulsification, film forming, suspension, adsorption, gel, surface activity, water retention and colloid protection. Hydroxypropyl methyl cellulose and methyl cellulose can be used in building materials, coating industry, synthetic Resin, ceramic industry, medicine, textile, agriculture, daily chemical and other industries.
2. Improve the wet strength and the adhesion of the plate after extrusion.

Ancient architecture is a historical relic and a resource of culture. It has undergone countless times and the baptism of nature. They are non-renewable and modern lighting design and implementation must be achieved with reliable protection. This is different from the general lighting requirements for the lighting of ancient buildings.
The ancient buildings are exposed to the sun and ultraviolet rays during the day, and they are exposed to ultraviolet rays from high-pressure gas discharge lamps at night, which accelerates the damage of the appearance of ancient buildings. In recent years, LED lighting equipment has developed rapidly, and various professional lamps can better meet the needs of special decorative lighting such as ancient buildings. It not only has the characteristics of small size, low power, and saturated color, but also does not have ultraviolet light. The shape of the daytime lamp will not affect the overall landscape of the building, and it will not cause ultraviolet damage to buildings and night sky at night, but also the building. The appearance of the object is beautifully decorated.
In ancient architectural lighting, LEDs show unparalleled advantages:
First, the safety of the lighting system: LED light source power is all low-voltage drive, solve the heat dissipation problem without large heat accumulation, the requirements of safety and fire protection are easy to meet.
Second, the green lighting products: the light source does not have infrared and ultraviolet light, will not destroy the cultural relics, while the light source does not contain mercury, will not cause environmental pollution, is a true green lighting products.
Third, the small size in the design of the full play of the space with point lighting, surface lighting, local lighting features, suitable for art lighting display, design space is very large.
Fourth, long service life, up to tens of thousands of hours, low maintenance and maintenance costs.
Among them, Pinergy Optoelectronics specializes in the characteristics of ancient buildings, using LumiLEDs1W high-power ultra-high brightness LED, developed an ancient architectural LED flood light. Its installation is simple and versatile, and the style is novel and exquisite, which not only can meet the demand of illumination brightness, but also because it is small, the light source can not be seen during the day. Therefore, it will not destroy the beauty of the ancient buildings during the day. This product has been used in Xi'an, Tengchong County and Yunnan Shunqiao Township in Yunnan Province, and has won great praise from lighting designers and owners.
It is hoped that in the near future, more and more Chinese ancient buildings will show their more charming charms under the backdrop of ultra-high brightness LEDs.

Application field:
â—† Cement-based plastering
1. Improve the uniformity, make the plastering easier to apply, and improve the anti-sagging ability. Enhance mobility and pumpability to improve work efficiency.
2. With high water retention, it can prolong the working time of mortar, improve the working efficiency, and help the mortar to form high mechanical strength during the solidification period.
3. The air infiltration is controlled to eliminate the micro-cracks of the coating and form an ideal smooth surface.
â—† Light board
1. It enhances the machinability of the extruded lightweight board, and has adhesive strength and lubricity.
2. High water retention, extending the working time of mortar, and producing high mechanical strength during solidification.
3. By controlling the uniformity of mortar consistency, a high-quality surface coating is formed.
â—† Masonry mortar
1. Enhance the adhesion with the masonry surface, and can enhance the water retention, so that the strength of mortar can be improved.
2. Improve the lubricity and plasticity to improve the construction performance. The use of cellulose ether reinforced mortar is easier to use, save time, and improve cost efficiency.
3. The model with special high water retention is available for the bricks with high water absorption
â—† Plate joint filler
1. Excellent water retention, can prolong the cooling time and improve work efficiency. High lubricity makes application easier and smoother.
2. Improve the shrinkage resistance and cracking resistance, and improve the surface quality.
3. Provide a smooth and uniform texture, and make the bonding surface more adhesive.
â—† Tile adhesive
1. The dry mixing ingredients are easy to mix without agglomerates, thus saving working time. As the application is faster and more effective, it can improve the constructability and reduce the cost.
2. The tiling efficiency is improved by extending the cooling time. Achieve adhesion effect.
3. Special development models with high skid resistance are available.
â—† Water-based paint and paint remover
1. The storage life is extended by preventing solid precipitation. It is compatible with other components and has high biological stability.
2. It dissolves quickly without lumps, which helps to simplify the mixing process. The cold water dispersion model can make the mixing faster and more convenient,And it does not produce lumps.
3. It produces favorable flow characteristics, including low splashing and good leveling, which can ensure excellent surface finish and prevent paint sagging.
4. Enhance the viscosity of water-based paint remover and organic solvent paint remover, so that the paint remover will not flow out of the workpiece surface.
â—† Self-leveling floor materials
1. It provides viscosity and can be used as an anti-settlement agent.
2. Enhance mobility and pumpability, thus improving the efficiency of paving.
3. Control water retention to greatly reduce cracking and shrinkage.
