Abstract
The invention discloses chalk dusts to recycle production technology, it includes the following steps：After the chalk dust being collected into is poured into container, suitable hypochlorite solution's bleaching is added in, and pass through varying pitch bar and apply pressure, chalk dust is pressed into slurry press-in molding outlet, obtains chalk mortar, it is spare as filler；By following raw materials of proportion by weight, turpentine oil, cera alba, nonionic surfactant, linseed oil, food-grade colorant after mixing, stirs 1 2h at 90 95 DEG C, obtains beeswax base-material；Above-mentioned beeswax base-material and chalk mortar are pressed into quality proportioning 1 again：35 mixing by hot briquetting mold output chalk, then are cut by disconnecting device a bit of, by natural air drying, obtain finished product.Utilize the chalk dust for the recycling that erases the board, it is processed, add in turpentine oil, cera alba, linseed oil, the chalk similar to wax crayon performance is produced, not loose colour, also easily wiping, add nonionic surfactant, so that color is more bright-coloured, food-grade colorant more safety and environmental protection so that traditional chalk quality is more preferable.
Description
Technical field
The present invention relates to a kind of chalk dusts to recycle production technology.
Background technology
General classroom is imparted knowledge to students using traditional blackboard, blackboard eraser, chalk pattern, and chalk dust problem is this among these
The major issue of influence teachers and students' health present in pattern.Statistical analysis shows that the 90% of chalk dust derives from
Flying upward for the accumulation dust of blackboard eraser is flown upward with the dust caused by grey reentrainment of dust that falls.
The problem of how collecting chalk dust, chalk dust utilized once again, reducing secondary pollution.
Therefore, it is necessary to it further makes improvements to solve the above problems.
Invention content
The technical problem to be solved in the present invention is to provide a kind of chalk dusts to recycle production technology.Chalk dust is sharp once again
With reduction secondary pollution.
To solve the above problems, the technical solution adopted in the present invention is：
Chalk dust recycles production technology, it includes the following steps：
After the chalk dust being collected into is poured into container, suitable hypochlorite solution's bleaching is added in, and pass through varying pitch bar and apply pressure
Chalk dust is pressed into slurry press-in molding outlet, obtains chalk mortar by power, spare as filler；
By following raw materials of proportion by weight, turpentine oil：15~18 parts, cera alba：50~58 parts, non-ionic surface active
Agent：4~7 parts, linseed oil：16~22 parts, food-grade colorant：5~8 parts, with 1800~2000 turns after mixing
/ point speed, at 90~95 DEG C stir 1~2h, obtain beeswax base-material；Again by above-mentioned beeswax base-material and chalk mortar
Material is by quality proportioning 1：3-5 is mixed, and by hot briquetting mold output chalk, then by disconnecting device to be cut into one small
Section, by natural air drying, obtains finished product.
The food-grade colorant is capsanthin, famille rose, lemon yellow, brilliant blue or melanin.
The nonionic surfactant includes one or both of fatty alcohol polyoxyethylene ether and alkyl glycosides.
The advantageous effect that the present invention is reached：Using the chalk dust for the recycling that erases the board, it is processed, adds in turpentine
Oil, cera alba, linseed oil produce the chalk similar to wax crayon performance, not loose colour, and also easily wiping, adds nonionic table
Face activating agent so that color is more bright-coloured, food-grade colorant more safety and environmental protection so that traditional chalk quality is more preferable.
Specific embodiment
In order to deepen the understanding of the present invention, the specific embodiment of the present invention is described below in detail, which is only used for solving
The present invention is released, is not restricted the protection scope of the present invention.
