1: 폴리에틸렌 폼 간지(시트, sheet).1: Polyethylene foam sheet.
2: 대전방지 고분자 시트.2: Antistatic Polymer Sheet.
본 발명은 전자부품(액정)을 적재 운반중에 표면 보호와 정전기에 의한 악영향을 방지할 수 있도록 합지공정에 의하여 제조되는 대전방지기능을 가진 폴리에틸렌(PE, Polyethylene) 폼 간지에 관한 것이다.The present invention relates to an antistatic function polyethylene (PE, Polyethylene) foam interlayer produced by the lamination process to protect the surface and prevent the adverse effects of static electricity during the transportation of electronic components (liquid crystal).
본 발명에 의하여 제조된 대전방지기능을 가진 폴리에틸렌 폼 간지는 합지공정을 통하여 이루어짐에 의하여 무엇보다도 반영구적인 대전방지 기능과 제조단가의 절감으로 가격 경쟁력을 가진다.Polyethylene foam sheet having an antistatic function produced according to the present invention is made through a lamination process and above all have a semi-permanent antistatic function and cost reduction in manufacturing cost.
상기 언급된 전자부품(액정)은 특히 인-주석 산화물 글라스(ITO(Indium-Tin Oxide) Glass, 이하 아이티오글라스이라고 명명함)에 해당하는 것으로 먼지 및 이물에 표면을 보호하여야 하며, 이동중에 발생하는 충격이나 낙하 등에 의한 보호가 필요한 부품으로 이를 안정하게 보호할 수 있는 제품을 필요로 함에 의하여, 본 발명은 폼(form)제품으로 충격 등에 제품을 보호할 수 있는 역활과 대전방지기능으로 이물흡착이나 흡착되어진 이물의 제거가 용이하게 할 수 있는 기능을 발휘할 수 있도록 이루어진 것이 특징이다.The above-mentioned electronic parts (liquid crystal) are especially phosphorus-tin oxide glass (ITO (Indium-Tin Oxide) glass, hereinafter referred to as ithio glass) to protect the surface from dust and foreign substances, and occurs during the movement By requiring a product that can protect it stably with a part that needs to be protected from impact or drop, the present invention is a foam product, which serves to protect the product from impact, etc. It is characterized in that it is made to exhibit a function that can facilitate the removal of foreign matter adsorbed.
