[0019] Make 2 kilograms of wax liquid, its proportioning is as follows: dewaxing bleaching shellac 14%; Ammonia 2.99%; Polydimethylsiloxane 0.01%; Water 83%.
[0020] Weigh 280 grams of dewaxed bleached shellac, 59.8 ml of ammonia (concentration 25%), 1660 ml of water, and 0.2 gram of polydimethylsiloxane. First, dilute 59.8ml of ammonia water with 1660ml of water, heat it to 60-80°C in a water bath, add 280 grams of dewaxed bleached shellac directly into the diluted ammonia water, stir until the shellac component is dissolved, then filter to remove undissolved substances. Add 0.2 g of polydimethylsiloxane, and stir to mix. Put the crude wax liquid overnight and filter again to obtain about 2 kilograms of shellac fresh-keeping fruit wax. It can be used to dip and coat about 200 kg of huanghuali.
