Poly Aluminium Chloride is referred to as PAC. It is also commonly called basic aluminum chloride or coagulant. It is a new type of high-efficiency inorganic polymer flocculant. Its aqueous solution is a hydrolysis product between aluminum trichloride and aluminum hydroxide, with a colloidal charge, so it has a strong adsorption on suspended matter in water. To achieve the purpose of condensing suspended matter in water. The Polyaluminium Chloride produced by Jinhe are white, yellow or light yellow powder.
Polyaluminum Chloride has the functions of removing suspended matter, COD and BOD, degreasing, decoloring, removing heavy metals and residual chlorine in water, etc. It is mainly used for purification treatment of tap water and industrial wastewater. Polyaluminum chloride is currently the most widely used inorganic coagulant in water purification processes. There is no need to adjust the pH value of the source water, it has a wide range of adaptation to the pH value of the source water, which is unmatched by traditional inorganic low molecular coagulants.
Polyaluminium Chloride is used in metallurgical, electric power, tanning, medicine, printing and dyeing, papermaking, chemical and other industries` sewage treatment.It`s also used in tap Water Treatment. Its coagulation effect forms flocs (also known as alum flowers) fast, the particles are large and heavy, and the sedimentation is fast. The applicable PH value ranges from 5 to 9, and has the characteristics of low dosage, low cost, high activity, convenient operation, wide adaptability, and low corrosion.

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.
