Surveyors use inspection instrument ( single - yarn strength tester ) toexamine the anti - tensility of the medical gut suture and the seam of needle and suture of the suture with needle . all the teste attained the state standard . the safcty and trustiness of the quality is ensured 检测员采用检测仪器（单纱强力机）对医用缝合线羊肠线进行抗张强度的试验及带线缝针的针、线衔接拉力的测试，都达到国家标准要求，在对产品质量的要求上，保证产品的安全性、可靠性。
It mainly uses in rubber tyre ( espacially in top grade tyre ) , acting as perfect add - adhesive , intenerate and fill - strive . it can shorten the molding time , increase tensile strength , elongationg rate and avulsion - resitant of glue . so it ' s the perfect assistant of making tope grade sole , sebific duct , adhesive tape and light rubber goods 主要用在橡胶轮胎中（特别是高档轮胎中） ，能起到理想的增粘剂、软化剂、补强剂的作用，并在加工过程中缩短塑炼时间，提高胶料的抗张强度、伸长率、抗撕裂，是制造高档鞋底、胶管、胶带及浅色橡胶制品的理想助剂。
Based on the investigation of extracting process , a new kind of collagen medical wound dressing was made with the obtained collagen protein . chitosan was introduced to improve the properties of film . the blending properties of collagen protein and chitosan were discussed in this paper 根据膜的使用特性要求，以成膜性能、抗张强度、断裂伸长率、吸水性和透明度等指标对膜进行评价，制备出适用于创伤敷料的胶原蛋白-壳聚糖膜，并对胶原蛋白与壳聚糖的共混性能进行了一系列研究。
