Abstract
The invention discloses a vacuum constant-force dehydration adsorption molding technology for pulp molded tableware. In the technology, a fluid body is directly molded into a container in the pulp fluid link. The technology comprises the following steps of: filtering pulp fluid on mesh cloth; performing adsorption molding by using vacuum and purpose-made die cavities; dehydrating and sucking up moisture by progressively increasing vacuum constant force until water content is reduced to be less than 75 percent; and curing.
Description
Affiliated technical field
The present invention relates to a kind of moulded pulp set for dining vacuum constant force dehydration adsorption forming technology.
Background technology
In the production process of moulded pulp set for dining, original technology is slurries to be copied into cardboard be moulded container again, and capacity and negative pressure are not enough and unstable when vacuumizing in the paper matrix environment protecting tableware production process; In the production technology of original paper environmental protection tableware, be slurries to be copied into cardboard be covered with plastic foil and be moulded container again.This kind technology belongs to plane papermaking, the cost height, and the goods result of use is poor, is not environment-friendly products completely.Important techniques of the present invention be exactly in the slurries link with the direct moulding one-tenth container of fluid, skipped some links with frontal plane papermaking; The present invention be with dope filtration on screen cloth, by vacuum and special die cavity by its adsorption forming, directly realize three-dimensional papermaking and increase progressively the dehydration suck dry moisture by the vacuum constant force again, and emphasis has solved the problem of capacity and negative pressure deficiency when vacuumizing in the production process, row solidifies again, improve output, reduced energy consumption.
Summary of the invention
In view of the body paper modular ring is protected in the tableware production process; not enough and the unsettled situation of capacity and negative pressure when vacuumizing; the present invention adopts vacuum constant force dehydration adsorption forming technology; in paper mould environment protecting tableware production process with dope filtration on screen cloth; by vacuum and special die cavity by its adsorption forming; form the cutlery box shape, increase progressively the dehydration suck dry moisture by the vacuum constant force again.Before product molding and in the forming process, its blank water content reaches 97.5%, the moisture of how removing after the moulding is to fall energy consumption in this technology, it is the key of putting forward output, increase progressively the dehydration suck dry moisture by the vacuum constant force among the present invention, allow its water content drop in 75%, row solidifies again, thereby realizes from plane papermaking to three-dimensional papermaking.Its technological process is as follows:
The invention has the beneficial effects as follows
Through overtesting, the utilization of vacuum constant force dehydration adsorption forming technology is adopted directly mouldingly, avoids passing through copying the paper link again, need applying glue outside paper surface yet, more save more environmental protection of cost; More can drain moisture, more can improve output, more cut down the consumption of energy.
Claims (3)
1. moulded pulp set for dining vacuum constant force dehydration adsorption forming technology, its technological core are exactly with the direct vacuum constant force of the fluid moulding one-tenth container that dewaters in the slurries link.
2. slurry fluids as claimed in claim 1 is moulding, it is characterized in that dope filtration on screen cloth, by vacuum and special die cavity by its adsorption forming.
3. vacuum constant force dehydration as claimed in claim 1 is characterized in that increasing progressively the dewater unit suck dry moisture by the vacuum constant force, allows the blank water content drop to 75%.
