Abstract
The invention provides a basalt scraper. The substrate is prepared by binding a basalt fiber cloth and a glass fiber cloth through utilizing bonding agent; the bonding agent is liquid resin glue; the basalt scraper is prepared by the following steps of: pre-dipping the basalt fiber cloth and the glass fiber cloth by glue, cutting, spreading, raising temperature, pressurizing and solidifying to form a sheet material; then splitting, milling and edging. At the edged end of the scraper, the angle of the cutting edge is 20-60 DEG, the thickness of the scraper is 1.5-5 mm and the width is 76-200 mm; and the length is customized according to the requirements. The other end of the scraper is a connection end and can be connected with a knife rest through utilizing a U-shaped tank or a rivet to rivet or utilizing the rivet to rivet after installing a butterfly sheet or utilizing a milling platform stage surface and the like. The basalt scraper provided by the invention has the advantages of high-temperature resistance, high strength, convenience in production, low cost and convenience in using.
Description
(the dispatch sequence number: what requirement 2010122400343090) was carried out divides an application the application according to sending the documents " division leads to notice " on December 29th, 2010.The applying date of original application case is on October 16th, 2009, and application number is 200910210727.1, and invention and created name is " basalt scraper and a manufacture method thereof ".
