Beschreibung
Zusammenfassung:	The invention relates to a process of preparing anti-hurricane glass, comprising following steps: cutting and edging glass; heating glass in the tempering furnace to softening point; feeding the glass into cooling room at speed of 25-50 cm/ s, the air pressure in cooling room should be controlled at 6.5-7.5 * 103 Pa to make the surface compressive stress reach to more than 150 MPa; putting glass into acid-etching slot for suitable acid etching; washing glass surface with clean water; coating the surface with organic silicon protecting membrane. The invention is characterized by low production cost and short producing time.
