<P>PROBLEM TO BE SOLVED: To solve the problem wherein conventional plastic products, especially bath tubs, have no heat-retaining property and therefore require the use of electric or gas energy for heat retention and, especially bath tubs as well as water tanks, have poor antibacterial property and cannot ensure sanitation. <P>SOLUTION: The exterior or the interior of the plastic product is partially or entirely coated with a ceramic powder mixed into a binder. The ceramic powder is obtained by compounding 30-70% silicon oxide, 10-30% aluminum oxide, 3-10% calcium oxide, 0.1-0.5% chromium oxide, 0.05-0.2% manganese oxide, 3-9% iron oxide, 0.05-2% cobalt oxide, 0.4-2% potassium oxide, 1-6% sodium oxide and 0.4-2% magnesium oxide to obtain a mixture wherein the balance is normal impurities, grinding the mixture, kneading it with water to achieve a clay-like form which is subsequently formed it into a mass and drying and firing the mass which is subsequently pulverized into a powdery form, wherein 10-70% tourmaline and 5-30% titanium oxide are further added. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
