Original Title: Introduction to Disposable medical protective suit PE Breathable Film [List of Manufacturers Attached] Since the fight against the new coronavirus pneumonia epidemic, with the gradual resumption of work in enterprises, the shortage of medical protective products has been alleviated, but there is still a gap. Especially as the "battle gown" protective suit of medical staff, it is usually replaced every four hours, and the demand is huge. Figure Disposable protective suit Disposable medical protective suit materials need to meet the requirements of "three repellency and one resistance" (water repellency, blood repellency, alcohol repellency and antistatic). The composite material can be compounded by different materials, such as polyethylene/polypropylene spunbonded nonwoven cloth compounded with a breathable microporous film or other nonwoven cloth, or spunlaced nonwoven cloth compounded with a breathable microporous film, or wood pulp compounded spunlaced nonwoven cloth. In addition, some membrane materials made of polytetrafluoroethylene can be used to make high-end protective suit fabrics. Among these materials, breathable microporous films are particularly important. The so-called breathable film is a kind of functional inorganic product which is evenly mixed into the polyolefin raw material, so that the product can produce pores due to high stretching in the film forming process, thus having the functions of ventilation and moisture conduction; the functions of the breathable film are briefly described as water insulation and ventilation (moisture), taking the most commonly used PE breathable film as an example. 1. The principle of ventilation The principle is very simple: inorganic substance + stretching = micropores. In fact, the operation is very particular. Only the micropores with appropriate size and uniform distribution are effective, as shown in Figure 1: Expand the full text Figure 1: Effective pore size of a breathable film As shown in Figure 2 and Figure 3 below, insufficient stretching and too small pore diameter, insufficient stretching and no pore diameter, poor stretching and micropores with insufficient size can only be waste products. Figure 2: Comparison of pore size of breathable film 2. Basic film-forming principle of breathable film Film-forming principle of breathable film: PE + CaCO3 (masterbatch) film-forming stretched breathable film PE breathable film is made by blending LDPE/LLDPE polyethylene resin carrier with about 50% special calcium carbonate, extruding into film and directionally stretching to a certain ratio. As that polyethylene resin is a thermoplastic plastic material, the polyethylene resin can be stretch and crystallized unde certain conditions, the interface between the polymer and the calcium carbonate particles is peeled off dure stretching, winding pores or channels which are communicated with each other are formed around the calcium carbonate particles, and the pores and the channels endow the film with a ventilation (moisture) function, so that the environments on both sides of the film are communicated. 3. Action mechanism of gas permeable membrane A humidity gradient pressure difference is formed when the water vapor concentration on one side of the membrane is greater than the environment on the other side of the membrane. This provides the basic condition for gas (vapor) convection, and the humidity environment on both sides of the film tends to be relatively balanced due to the formation of convection. The breathable membrane is used as a water barrier membrane, which has a barrier effect on liquid. Because there are many paths in the membrane, the "length-diameter ratio" (L/D) value of the tortuous channel formed by the membrane is very large, which can be understood as capillary. Therefore, in the case of the same liquid (such as water) and the same pressure, as long as the liquid column height of the capillary is less than the length of the capillary, it can ensure that the liquid will not leak out. Protective suit Breathable Film Raw Material Manufacturer PE breathable film raw material manufacturers are Golden Hair Technology, Honghe, Gaia, etc., many breathable film manufacturers also have their own modified granulation, the following is part of the protective suit PE breathable composite film raw materials and processing manufacturers, for reference, if there are errors or omissions can be added to the message; 1.
