Abstract
The invention relates to the process of paste used in molding environmental protective dinnerware and the method of adding paper pulp board fiber into mixer, belonging to the manufacturing technology of environmental protective dinnerware. It is characterized in that: the paper pulp board is cut into strips and added water in the rate of 1:35 to put into inundator; the mixed strips are put into mixer with 40 % starch, 15 % polyvinyl alcohol in 5 % concentration; the two-throw screw in the mixer is droved to conversely circumrotate the mixer to mix the material fully. Said method has strong strength of mixing, uniform mixed paste, and the fiber of inundated paper pulp strips will not be destroyed. Since the length of paper pulp board fiber is uniform, the thickness of finished dinnerware and the cost will be reduced.
Description
One, technical field: the present invention relates to the making of a kind of environment protecting tableware moulding with slurry, and the method that adds the pulp board fiber in batch mixer.The invention belongs to environment protecting tableware manufacturing technology field.
Two, background technology: at present, produce environment protecting tableware moulding slurry, generally adopt by pulverizer raw material pulverizing, directly drop in the agitator by formula rate and stir, (number of patent application is: 93109998.6).When particularly containing the pulp board fibre composition in environment protecting tableware, to the processing of pulp board fiber, the employing pulverizer that has is pulverized pulp board and is the directly use of velvet-like back; After the employing that has is pulverized paper pulp earlier, stir together with other adding ingredients again that (number of patent application is respectively: 98111941.7,94209590.1).
Three, summary of the invention: difficulty is big, energy resource consumption is big in view of at present the processing aspect existence of pulp board fiber being pulverized; Pulp board after the pulverizing is velvet-like, is difficult for metering, is difficult for making slip to disperse, be difficult for mixing; Pulp board after crushed, the pulp board fiber is destroyed, directly influences deficiencies such as tableware product quality.The object of the present invention is to provide the making of a kind of environment protecting tableware moulding with slurry, and the method that in batch mixer, adds the pulp board fiber, to solve above-mentioned existing problems, prepare the moulding slurry of high-quality for producing environment protecting tableware.Content of the present invention is:
(1). environment protecting tableware moulding slurry is to form with mixing manufactures such as polyvinyl alcohol 15%, water 35% under starch 40%, paper pulp fiber 10%, 5% concentration,
(2). with 3～30 millimeters of pulp board cut growths, wide 2～8 millimeters paper pulp lath, quantitatively in input inundator, become 1: 3.5 ratio to add water-soaked with water with the paper pulp lath by prescription requirements in (1),
(3). adopt manually, also can adopt the method for machinery, paper pulp lath in the inundator and water were stirred for 3～30 seconds, make the paper pulp lath fully absorb water, soak into,
(4). by prescription requirement in (1), good paper pulp lath and water etc. will be soaked in polyvinyl alcohol and the inundator under starch, 5% concentration, drop in the batch mixer in the lump, one group of crutches spiral counter-rotating agitator is housed in the batch mixer, two counter-rotational gears are driven through reducing gear by power source, drive the crutches counter-rotating respectively, mix and stir material 5～30 minutes, the needed high-quality pulp of environment protecting tableware moulding promptly prepares success, and it is stand-by to put into storage bin hopper by discharging opening.The invention has the beneficial effects as follows: equipment is simple, and is easy to operate; After pulp board cuts into strip, be convenient to metering, be convenient to soak dispersion; Because of not destroying the pulp board fiber, make processing back pulp board fibre length even, not only can increase tableware finished product structural strength, and can reduce finished product tableware thickness, thereby reduce the tableware cost of goods manufactured; Crutches spiral counter-rotating agitator is housed in the batch mixer, to the existing squeezing action of slurry, the kneading effect is arranged again in the batch mixing process, make that the stirring dynamics is strong, slurry mixes, batch mixing efficient height, effective.
Four, description of drawings:
Figure one is environment protecting tableware moulding slurry manufacture craft flow process
Figure two is the batch mixer structure chart
Five, specific embodiments:, stand-by in the big packaging bag of packing into 15 millimeters of pulp board cut growths, wide 3 millimeters paper pulp lath; Paper pulp lath 10% by formula rate requirement weighing well cutting drops in the inundator, become 1: 3.5 ratio in inundator, to add water with water with the paper pulp lath, soak the paper pulp lath, in inundator, stirred for 15 seconds, the paper pulp lath is fully absorbed water with artificial or mechanical method; In batch mixer, add polyvinyl alcohol 15% under starch 40%, 5% concentration successively, reach and soak into good pulpboard bar and water etc. in the inundator by the formula rate requirement, one group of crutches spiral counter-rotating agitator is housed in the batch mixer 3, gear 1 and gear 2 are driven through reducing gear by power source, drive is turned 4, is turned 5 counter-rotatings, mix and stirred material 20 minutes, the needed high-quality pulp of environment protecting tableware moulding promptly prepares success, and it is stand-by to put into storage bin hopper by discharging opening 6.
