醫(yī)用透氣膠的涂布方法有哪些？
刮刀式涂布 利用刮刀的揩抹作用以達到將壓敏膠粘劑均勻涂抹在基材表面。
Scraper coating is made by wiping the scraper to achieve the uniform application of pressure sensitive adhesive on the surface of the substrate.
轉(zhuǎn)移涂布，將醫(yī)用透氣膠帶的基材（醫(yī)用無紡布）與預(yù)先涂有壓敏膠粘劑的防粘性基材（醫(yī)用硅油紙）加壓復(fù)合，從而使壓敏膠粉劑從醫(yī)用硅油紙的表面轉(zhuǎn)移到醫(yī)用無紡布上。
The substrate (medical nonwoven fabric) of the medical permeable adhesive tape is compacted with the anti sticky substrate (medical silicon paper) coated with pressure-sensitive adhesive (medical silicone paper) in advance to transfer the pressure sensitive adhesive powder from the surface of medical silicone paper to the nonwoven fabric.
凹印涂布 利用圓形棍筒表面上均勻或規(guī)則排布的凹印坑，將粘度小的液體膠均勻轉(zhuǎn)移到醫(yī)用透氣膠帶的基材上。
Gravure printing uses uniform or regularly arranged gravure pits on the surface of the circular cylinder to transfer the small viscosity liquid adhesive onto the substrate of the medical breathable adhesive tape.
擠出涂布 利用壓力將壓敏膠由縫隙中擠出，并涂抹于醫(yī)用透氣膠帶基材表面。
Extrusion coating uses pressure to squeeze pressure sensitive adhesive from the gap and smear it on the surface of medical breathable adhesive tape.
其實，醫(yī)用透氣膠帶基本上都屬于轉(zhuǎn)移涂布，先將醫(yī)用熱熔膠或醫(yī)用溶劑膠先涂布到醫(yī)用硅油紙上，然后經(jīng)過加壓復(fù)合將硅油紙表面膠黏劑轉(zhuǎn)移到醫(yī)用無紡布上，從而加工成醫(yī)用透氣膠帶，常見的擠出涂布主要用于熱溶膠，溶劑膠主要用刮刀涂布法，也有用凹印涂布法的。
In fact, the medical permeable adhesive tape is basically a transfer coating. First, the medical hot melt adhesive or the medical solvent glue is first coated on the medical silicone paper, then the silicone oil paper surface adhesive is transferred to the medical nonwoven fabric through pressure compound, and then the medical air permeable adhesive tape is processed. The adhesive is mainly coated with scrapers and gravure coating.
