<p>PURPOSE:To enhance the bonding strength of the fluoroplastic film bonded to the surface of the surface plate member of a gas range and the surface plate member. CONSTITUTION:The surface treatment method of the surface plate member of a gas range made of a steel plate or a stainless steel plate consists of a first process forming deep grooves(g) on the surface of the surface plate member 1 by etching, sandblasting or a cutter, a second process pressing and wetting the walls(w) of the grooves(g) formed on the surface of the surface plate member 1 to form the grooves(g) into a bottom wide shape having a narrow inlet, a third process placing a fluoroplastic film Ff on the surface plate member 1 to heat the same to the softening point to press the film Ff to the surface of the surface plate member 1 to perform primary bonding, a fourth process heating the surface plate member 1 having the fluoroplastic film Ff bonded thereto to the m.p. of fluoroplastic to liquefy the fluoroplastic film Ff and a fifth process cooling and solidifying the surface plate member 1 having the fluoroplastic film Ff in a liquefied state.</p> |
