流行病学研究 为了预防经尿道前列腺切除术后患者发生上行性尿路感染,研究了一种局部抗菌剂应用于腹股沟和外生殖器的使用。进行了一项前瞻性随机对照试验,其中50例患者每天应用2%多聚硝基纤维素粉,50例患者作为未治疗的对照组。治疗组和未治疗组的患者年龄和导管留置时间相似。在减少术后尿路感染方面,治疗组没有显示出显著的好处(P>0.05)。
/EPIDEMIOLOGY STUDIES/ To prevent ascending urinary infection in patients following transurethral prostatectomy, ...the use of a topical antibacterial agent applied to the groin and external genitalia /was studied/. A prospective randomized controlled trial was conducted, with 50 patients being treated by daily application of a 2% polynoxylin powder, and 50 patients acting as untreated controls. Patient age and duration of catheterization were similar in the treated and untreated groups. No significant benefit was seen in the treated cohort (P>0.05) in terms of reduction in postoperative urinary infection.

制备方法与用途

根据您提供的信息,以下总结了关于脲醛树脂的主要内容:

  1. 脲醛树脂是由尿素和甲醛在催化剂作用下缩聚而成的一种热固性树脂。

  2. 主要用途:

  • 木材、胶合板等的粘接剂
  • 家具制造
  • 农机具修理
  • 织物处理
  • 纸张处理
  • 制造各类日用品如瓶盖、钮扣等
  • 塑制电器元件、装饰件等
  1. 特点:
  • 无色透明或乳白色液体
  • 对粘接材料无污染性
  • 价格低廉,使用方便
  • 耐油、抗霉、耐光
  • 粘接力强,固化后硬度高
  1. 缺点:
  • 含有游离甲醛和甲酸,有毒性
  • 耐水性和强度较酚醛树脂低
  • 胶层易老化
  1. 改性方法:
  • 通过加入亚硫酸钠等进行磺化改性以提高溶解度和湿粘合性能
  • 加入多元胺、乙二胺等进行阳离子改性以增强增湿强效果
  • 制备粉状脲醛树脂延长存放期
  1. 生产工艺:由尿素与甲醛缩聚成低分子量初产物溶液,再经干燥得到固体产品。

总的来说,脲醛树脂是一种广泛应用的粘合剂材料,但也存在一些不足之处。通过改性可以进一步提高其性能。
