The main measures to improve the release rate of silkworm cocoons

Last year, some silkworms in the Xishan District of Wuxi City appeared to have sluggish sales, mainly because of the low rate of cockroach sampling. In spring this year, silkworms will go uphill again, and improving the rate of unwinding has become a top priority for the production of spring quails in the region. The unwinding rate is a measure of the ease of male disability dissociating males. The high dispelling rate indicates that the cocoon filaments are easily dissociated, which is conducive to reeling silk mills, and vice versa. In order to improve the quality of silkworm cocoons in Xishan District, the main measures to improve the unwinding rate are briefly described as follows: 1. The site must be dry and ventilated, and avoid dark and damp. Secondly, it is not advisable to spend too early on the clams in order to minimize the residual fecal urine in cooked silkworms; the density of the clams should not be too large. 3. Dry straw or newspapers shall be laid under the cooking utensils to absorb the mature silkworm excreta. After the camping starts, the hygroscopic material should be removed from the cooked room in order to reduce the total amount of indoor moisture. 4. During the captain's stay, the dormitory must open the window to facilitate ventilation and dehumidification. Fifth, in case of continuous rain or wet weather after the last time, artificial dehumidification measures can be used, such as the use of fans to remove moisture or dry lime moisture.

Maxillofacial Fixation

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.
