Abstract
The present invention discloses a kind of nano particle regenerated slurry paper. The material includes papermaking sewage slduge 20-80 wt%, paper pulp 20-80 wt%, nano level calcium carbonate material 20-10 wt% and coagualting chemical asssitant 1-5 wt%. The production process includes sequeezing and washing of papermkaing sewage sludge, adding nano level calcium carbonate material, paper pulp and in coagulating chemical assistant the pond, netting, squeezing, stoving and winding.
Description
Technical field
The present invention relates to a kind of regenerated mud paper, relate in particular to a kind of prescription and production technology of utilizing nanometer technology to make regenerated mud paper.
Background technology
Waste water of paper mill mud after treatment, fiber content is also very high, but general paper mill all abandons this mud as refuse, and the mud stacking needs the place, but also easily cause environmental pollution, though also there is the minute quantity paper mill to utilize this mud to make the mud cardboard, only be used for the mill blank of low-grade leather and fur products, price is low, slack market.So the development and use of mud cardboard have at present become both pollution abatements of papermaking enterprise, produce the key subjects of economic benefit again.
Current, this new and high technology of nanometer technology begins to apply, and is mainly used in the industries such as plastics, synthetic fiber, magnetic material, coating and printing and dyeing, catalyst, pottery and battery.Nano material has performances such as physics than traditional material excellence, chemistry, machinery, biology, and the not available distinctive performance of many traditional materials arranged, so, nano material is applied in the traditional material, be used for improving effectively the performance and the class of numerous traditional material products, make traditional product obtain updating.And nano material is applied to paper industry, still in the experimental study stage.Simultaneously, utilize nanometer technology, being applied to regenerated mud papermaking also is the target that present papermaking enterprise is explored.
Summary of the invention
The object of the invention is to provide a kind of applying nano technology, with the nano narticle regneerated slurry paper and the production technology thereof of papermaking wastewater mud development and use.
For achieving the above object, technical solution of the present invention is: nano narticle regneerated slurry paper, the mud that papermaking wastewater is produced after the floating physical treatment of vapour is as base-material, and applying nano calcium carbonate and electronegative macromolecule emulsifier and third rare amide monomer are that the chemical assistant that plays cohesion that main polymer is formed produces.Because nanometer grade calcium carbonate has surperficial suction-operated, electronegative macromolecule emulsifier and third rare amide monomer are that the chemical assistant that main polymer is formed has the adsorpting polymerization effect, wrap up some tiny fibers, attached planting on the paper, thus improve the quality of paper greatly.
The parts by weight of the component of nano narticle regneerated slurry paper of the present invention are: papermaking wastewater mud 20-80, paper pulp 20-80, nano grade calcium carbonate material 2-20, the chemical assistant 1-5 of a cohesion.The chemical assistant that wherein plays cohesion includes electronegative macromolecule emulsifier and third rare amide monomer is main polymer.This percentage by weight that plays the chemical assistant each component of cohesion is: electronegative macromolecule emulsifier 30-40%, acrylamide monomer are main polymer 35-45%, and surplus is an additive.
Technological process of the present invention is: mud mud squeezing is cleaned (filtrations) and is gone into the pond and add chemical assistant that nanoscale calcium carbonate material blending paper pulp reach cohesion and mix to surf the Net to squeeze and dry the paper delivery rewinding and go out finished product.
Advantage of the present invention is: 1, this new and high technology of applying nano technology is made nano narticle regneerated slurry paper, because nanometer grade calcium carbonate and electronegative macromolecule emulsifier and third rare amide monomer are that the chemical assistant that main polymer is formed has fiber adhesion, cohesion, improved the quality and the performance of paper, fineness, pull resistance, durability, the folding strength of paper are improved significantly.2, make full use of and abandon and the papermaking once again of no papermaking mud, reach make a silk purse out of a sow's ear, the purpose of resource regeneration, energy savings.3, environment purification reduces and pollutes, and protection is ecological.4, replace normal body paper, save cost, economic benefit is considerable.5, product is used for corrugated board manufacturing paper, reaches normal technical indicator.The present invention is applicable to the processing of paper mill papermaking wastewater mud.
The specific embodiment
The present invention is described in further detail below in conjunction with embodiment.
Because papermaking mud is the refuse after the papermaking, contain the fiber of some, and these mud are surfed the Net owing to too thin short being not easy to, number of dropouts is big, thus to add the paper pulp and the additive of some, to increase its fibre concentration.
EXAMPLE l: get 70 kilograms in papermaking mud, 20 kilograms of paper pulp, 5 kilograms of nano grade calcium carbonate materials, 5 kilograms of chemical assistants, wherein electronegative macromolecule emulsifier and third rare amide monomer are that main polymer respectively accounts for 32% and 36%, and surplus is an additive.Earlier papermaking mud is squeezed, add in the pond that with reentering after the clear water cleaning and filtering paper pulp, nano grade calcium carbonate material and electronegative macromolecule emulsifier and third rare amide monomer are the chemical assistant that main polymer is formed, stir mixed, the mud of mixing thoroughly is dried the nano narticle regneerated slurry paper that gets product with being pumped to the paper production line online, squeezing.
Embodiment 2: get 64 kilograms in papermaking mud, 30 kilograms of paper pulp, 3 kilograms of nano grade calcium carbonate materials, 3 kilograms of chemical assistants, wherein electronegative macromolecule emulsifier and third rare amide monomer are that main polymer content is respectively 36%, 40%, and surplus is an additive.Earlier papermaking mud is squeezed, add in the pond that with reentering after the clear water cleaning and filtering paper pulp, nano grade calcium carbonate material and electronegative macromolecule emulsifier and third rare amide monomer are the chemical assistant that main polymer is formed, stir mixed, the mud of mixing thoroughly is dried the nano narticle regneerated slurry paper that gets product with being pumped to the paper production line online, squeezing.
Embodiment 3: get 55 kilograms in papermaking mud, and 35 kilograms of paper pulp, 8 kilograms of nano grade calcium carbonate materials, 2 kilograms of chemical assistants, wherein electronegative macromolecule emulsifier and third rare acid amides unit are that main polymer is respectively 39% and 43%, surplus is an additive.Earlier papermaking mud is squeezed, add in the pond that with reentering after the clear water cleaning and filtering paper pulp, nano-calcium carbonate calcium material and electronegative macromolecule emulsifier and third rare acid amides unit are the chemical assistant that main polymer is formed, stir mixed, the mud of mixing thoroughly is dried the nano narticle regneerated slurry paper that gets product with being pumped to the paper production line online, squeezing.
