Late-maturing apple orchards should generally be covered with reflective film from the end of September to the beginning of October. Laying a reflective film in the orchard is to improve the lighting conditions of the entire orchard, especially the canopy and lower skirt, through the reflection and radiation of the reflective film to the sun. The number of whole red fruits, thereby achieving the purpose of improving the appearance quality of apples. Laying a reflective film can not only promote fruit coloring, but also improve fruit tree photosynthesis, thereby increasing yield. In addition, the reflective film can also be used repeatedly to reduce the cost of use. Generally, silver-white aluminum-plated film is available.

Maxillofacial fixation system -- micro-plate for cranial and maxillofacial fracture fixation, designed for the surgical treatment of maxillofacial trauma fractures, suitable for the forehead, nose, orbit, zygomatic, maxillary region, and pediatric craniofacial bones.
The system is an orthopedic surgical instrument for neurosurgical tools. The maxillofacial fixation system includes micro-plates, straight plates, L-shaped plates, T-shaped plates, Y-shaped plates, double Y-shaped plates, H-shaped plates for cranial and maxillofacial fractures. The product range is complete, covering three-dimensional titanium mesh, self-drilling rotary bone screws, anatomical orbital floor plates, orthodontic nails, etc. However, the facial anatomical structure is special, and the screw plate needs to be placed away from the fracture line and avoid important anatomical structures such as nerves and teeth roots. Therefore, the specifications of the screw plate system are required to be as diverse as possible in order to be used in different bone structures, such as different radian, length, and number of screw holes. The bone plates forcranial and maxillofacial fractures are mainly divided into 1.5mm, 2.0mm and 2.4mm systems.
Titanium (including pure titanium and titanium alloy) is the most common material for hard tissue implants. Its elastic modulus and tensile strength are higher than those of human bone, and it is better than other metal materials such as nickel-titanium alloy and cobalt-chromium alloy in terms of biocompatibility and corrosion resistance. Our maxillofacial plate is made of titanium, and the self-tapping screws are mainly made of titanium alloy.
Jaw fractures include maxillary fractures and mandibular fractures. According to whether the fracture trauma is exposed, it can be divided into open fracture and closed fracture. Trauma is the most common cause of jaw fracture, which usually includes hit, traffic injury, fall injury, firearm injury, and a few iatrogenic injuries. All are caused by external forces acting directly or indirectly on the maxillofacial region. With the popularization of motor vehicles, the proportion of jaw fractures caused by traffic accidents has increased year by year, which has become the main cause of jaw fractures. In addition, neoplastic lesions in the maxillofacial region often lead to pathological jaw fractures.
In summary, maxillofacial fixation system has been widely used in clinical maxillofacial surgery, plastic surgery and ENT, and has a relatively mature market.
