          降低醫用防護服成本需要怎樣制作哦防護服?

          來源:http://www.onews24.com 日期:2020-05-08 發布人:admin      

          每天跟血液、病毒、細菌打交道的“白衣天使”正時刻處于高風險之中,他們保衛著病人的健康,又是誰來保衛他們的健康?治療新冠病毒肺炎重癥患者,需要消耗10套防護服嗎?單件防護服成本接近三四百元嗎?當前疫情防控形勢下,身著防護服的“白衣天使”形象不斷刷屏,然而防護服也成為中國防疫急需物資之一。
          The "angels in white" who deal with blood, viruses and bacteria every day are at high risk. They are protecting the health of patients. Who is going to protect their health? Does the treatment of severe patients with new coronavirus pneumonia need to consume 10 sets of protective clothing a day? Is the cost of a single protective suit close to 340 yuan? Under the current situation of epidemic prevention and control, the image of "angel in white" wearing protective clothing is constantly brushing the screen. However, protective clothing has also become one of the urgently needed materials for epidemic prevention in China.

          Water repellent, blood repellent, alcohol repellent + antistatic
          防護服不僅要排濕透氣、穿著自如,還要讓醫護人員免受診療過程中病毒、細菌等各種污染物的感染,抵擋住水液、酒精、油漬侵入,而且要有效抗靜電,甚至防止灰塵進入。
          The protective clothing shall not only be moisture and air permeable, and be worn freely, but also prevent the medical staff from being infected by various pollutants such as viruses and bacteria in the process of diagnosis and treatment, resist the invasion of water, alcohol and oil stains, and effectively resist the static electricity, even prevent the dust from entering.
          由于采用微納米級別的醫衛防護非織造材料,防護服的基本要求就是“三拒一抗”,即拒水、拒血液、拒酒精以及抗靜電。靳向煜進行科普說,這樣的復合材料可以通過不同材料復合,如用聚乙烯/聚丙烯紡黏非織造布,與透氣微孔薄膜或其他非織造布復合,或用水刺非織造布與透氣微孔薄膜復合,或用木槳復合水刺非織造布。
          Due to the use of micro nano medical nonwovens, the basic requirement of protective clothing is "three repellents and one anti-static", that is, water repellent, blood repellent, alcohol repellent and anti-static. According to Jin Xiangyu, such composite materials can be compounded by different materials, such as polyethylene / polypropylene spunbond nonwovens, air permeable microporous films or other nonwovens, spunlaced nonwovens and air permeable microporous films, or wood oars.

          值得注意的是,防護服材料的幾種性能有嚴格標準,包括防護性(密封性)、服用性、安全衛生性。其中防護性要求具有液體阻隔功能,防護服關鍵部位(左右前襟、左右臂及背部位置)帶著抗滲水性,可耐靜水壓不低于1.67千帕(kPa);抗合成血液穿透性不低于2級,即合成血液以1.75千帕的壓強作用于防護服上,5分鐘后不得穿透;同時,防護服外側面沾水等級不低于3級。此外,還要防微顆粒物穿透,關鍵部位及接縫處對非油性顆粒物的過濾效率不低于70%。
          It is worth noting that there are strict standards for several properties of protective clothing materials, including protection (sealing), wearing, safety and health. Among them, the protective function is required to have liquid barrier function. The key parts of the protective clothing (left and right front, left and right arms and back positions) are water resistant, and the hydrostatic pressure resistance is not less than 1.67kpa; the penetration resistance of synthetic blood is not less than level 2, i.e. the synthetic blood acts on the protective clothing with a pressure of 1.75kpa, and shall not be penetrated after 5 minutes; at the same time, the water level on the outer side of the protective clothing is not Below level 3. In addition, it is necessary to prevent the penetration of micro particles. The filtration efficiency of key parts and joints for non oil particles shall not be less than 70%.
          對于服用性要求,防護服要有足夠強度和尺寸穩定性,進行拉伸試驗時,斷裂強力不低于45牛,斷裂伸長率不低于30%;穿著舒適性方面,防護服材料具有透濕量要求。而安全衛生性則要求自身無毒,無皮膚刺激性,抗霉菌滋生。
          For the wearing requirements, the protective clothing shall have sufficient strength and dimensional stability. During the tensile test, the breaking strength shall not be less than 45 n, and the elongation at break shall not be less than 30%; for the wearing comfort, the protective clothing material shall have the moisture permeability requirements. But the safety and health requires that it is non-toxic, non irritating and anti mildew.
