Durable

The transparent PVC gusset plate was introduced into Shouguang vegetable greenhouse in Shandong, China to solve the problems of fragile glass ceiling and rusty steel frame. The light transmittance of 12mm thick hollow board is 78%, and the ultraviolet transmittance is accurately controlled in the optimal growth range of crops. The intelligent temperature control test shows that the thermal insulation performance is 33% higher than that of glass in winter, and the temperature can be quickly reduced by 5℃ by adjusting the air flow in the interlayer in summer. Farmers found that the anti-dripping treatment on the surface of the plate made the condensed water flow away along the groove, and the mildew rate of leafy vegetables decreased by 27%. When the light is supplemented at night, the diffuse reflection characteristics improve the uniformity of light by 41%. The unexpected harvest was zero damage in hail weather. Last year, extreme weather saved 3.8 million yuan in economic losses. Attention should be paid to replacing the sealing strip every five years to prevent aging and air leakage.

Sanitary

In the renovation of key primary schools in Beijing, it was found that the sound absorption effect of traditional mineral wool board decreased year by year with the accumulation of chalk dust. After switching to double-layer hollow PVC sound-absorbing board, the classroom noise decreased from 65 decibels to 42 decibels, and the students' concentration test score increased by 19%. The innovative design lies in the porous structure formed by implanting regenerated particles of PET bottles into the board, and the absorption rate of low-frequency noise below 2000Hz is increased to 0.93. The teachers found that the beige surface enhanced the contrast of the projector by 28%, and the students in the back row could read the blackboard more clearly. The elastic suspension system is adopted during installation to effectively isolate the vibration and noise of the gymnasium upstairs. The unexpected harvest is that the amount of chalk dust attached is reduced by 64%, and the cleaning cost is saved by 24 thousand yuan every year. The Education Bureau specially stipulates that the purchased board should be accompanied by a third-party sound absorption test report to ensure that the performance attenuation does not exceed 15% within five years.

Commercial Value

ZARA's flagship store in Tokyo changes the display theme every month, and the printable PVC quick-loading roof becomes a trade secret. Digital inkjet technology realizes 24-hour ceiling pattern replacement, and the huge new poster with resolution of 360dpi is shocking. Magnetic splicing system allows three-dimensional decorative pieces to be superimposed on the original board, and Christmas ornaments and Valentine's Day light strings can be changed at will. The energy consumption monitoring shows that the white reflector reduces the lighting demand in the store by 32% and the air conditioning load in summer by 19%. The solution to fire hazards is exquisite: each board is pre-embedded with flame retardant strips, which will automatically fuse in case of fire to form a fire isolation belt. The store manager revealed that the ceiling advertising space has begun to attract foreign investment, and the monthly efficiency has increased to 270,000 yen/m 2.

Application

Xiaomi Eco-chain launched the "Smart Skyscreen System" to upgrade PVC board to the home control center. The plate is integrated with millimeter wave radar, which can identify the falling action and give an alarm automatically; The temperature and humidity sensor is linked with air conditioning, which is 1.8 seconds faster than the wall regulation response. DIY mode allows users to splice the touch area-tap the curtain on the ceiling and slide to adjust the color temperature of the light. In terms of privacy protection, the electromagnetic shielding layer reduces the leakage of WiFi signal by 26dB, and the infrared mode can generate a virtual skylight scene. The pressure test shows that the system runs stably in the extreme environment from -20℃ to 60℃, and the supercapacitor maintains its basic function for 72 hours during power failure. The first batch of users need to reserve a height of 5cm for tucao installation, but 90% think it is worth sacrificing space for future experience.
