(2) disposable gypsum meal spoon manufacture method:
1, starch pasting technology in the disposable gypsum meal spoon raw material:
Starch is added clear water put into the gelatinization cylinder; stir; make the abundant water-swelling of starch be made into 10%～30% suspension; selecting solid content (purity) in the embodiment of the invention table for use is that (selecting solid content (purity) for use is 15% pasted starch for 15% pasted starch;, be not qualification just) to protection domain of the present invention for the ease of calculating the raw material percentage composition.By 85～90 ℃ of steam-heated cal(l)andria, being incubated 15 minutes can finish again.
2, polyvinyl alcohol aqueous solution system method in the disposable gypsum spoon raw material:
The polyvinyl alcohol resin-oatmeal was added the clear water bubble more than 30 minutes; be made into 20%～80% mixed solution; selecting solid content (purity) in the embodiment of the invention table for use is the 50% polyvinyl alcohol aqueous solution (selecting solid content (purity) for use is that the 50% polyvinyl alcohol aqueous solution is for the ease of calculating the raw material percentage composition, is not the qualification to protection domain of the present invention).Again by in 90～100 ℃ the steam-heated cal(l)andria still heating and stirred 15 minutes, the water white transparency polyvinyl alcohol aqueous solution.
3, terra alba is added in the polyvinyl alcohol resin aqueous solution, can add food flavour, pigment stirs into pasty state through stirrer.
4, slurry is injected gypsum mold took out in 1～60 minute.
5, blank is sent into 40～90 degree drying sheds or oven dry kiln dry, can be through being packaged into finished product.
(3) disposable gypsum tableware WATER REPELLENT and production technique:
1, directly mixes the raw material waterproof.The waterproof raw material generally adopts import food grade silicone oil, by emulsifying agent emulsification, adds materials (being food grade) such as stablizer and toughener simultaneously and synthesizes.The waterproofing agent of organosilicon solid content is generally 8%～35%, and present embodiment waterproofing agent of organosilicon solid content is selected 30% (the waterproofing agent of organosilicon solid content selects 30% for use just for the ease of calculating the raw material percentage composition, is not the qualification to protection domain of the present invention) for use.That this water-resisting agent has is nontoxic, harmless, tasteless, volume is few, can strengthen and keep characteristics such as gypsum self whiteness, with its synthetic gypsum slurry excellent waterproofness and adhesive property is arranged.Select different water-resisting agent incorporations according to the different class needs of product, be generally 5% of amount of gypsum, in pulping process, directly add with the water mixing.
2, appearance water-proof coating.With 1 part of water-resisting agent mix 10 parts of water rare after, dried disposable gypsum is immersed in the water-resisting agent after the dilution, take out then and dry or dry.
The manufacturing main raw material of disposable gypsum chopsticks and disposable gypsum spoon is a terra alba.Select for use and the consumption of tackiness agent kind how much be according to institute's production kind, class is different with requirement of strength and select the tackiness agent and the consumption of different varieties.Kind class difference has also determined to use the kind of water-resisting agent and whether add food dye, essence.
