Abstract
The present invention relates to the application of mineral fibers for papermaking processes, which belongs to the technical field of papermaking. The present invention is characterized in that the mineral fibres are used as substitutes for partial paper pulp and as papermaking raw materials. The mineral fibres as substitutes for paper pulp are added in the process of pulping after the process of paper pulp preparation, or sieved, filtered, edulcorated and added to the paper pulp before an addition agent is added. By using mineral fibres as substitutes for paper pulp and as papermaking raw materials, the present invention not only saves the use level of paper pulp, reduces the discharge amount of pulping polluted water and production cost and protects the ecological environment, but also improves the drainability of the pulp in the process of papermaking and increases the white content, the antistatic performance and the tearing toughness of finished product paper at different degrees.
Description
Technical field
The invention belongs to pulp technology for making paper, relate in particular to and use mineral fibres and add that part replaces paper pulp as paper making raw material in the paper pulp to.
Background technology
String in the raw material that paper industry is used is the main body of paper making raw material, and lumber fibre is the good raw material of papermaking.China's timber resources is more in short supply, and the grass raw material sources are abundant, and the large percentage that grass accounts in pulping raw material can produce a large amount of black liquor and waste water with timber and herbaceous plant slurrying the time, environment is polluted, and disposing of sewage also makes the cost of paper-making industry increase.Because China's timber resources lacks, in the age in the past, the utilization of non-wood-fiber has been played crucial effects to the development of China's pulp and paper industry, and the while has also brought many side effects to the environmental protection of China certainly.China researcher has successively developed various non-wood-fiber papermakings in recent years, replace ryegrass pulping with reed, bagasse and bamboo, but total size is less than normal, and pulping process complexity, pollution level do not change simultaneously.
Once having in the recent period utilizes the dried slag fiber of blast furnace to carry out the news report of composite papermaking, the diameter of the dried slag fiber of blast furnace is slightly lacked, impurity content is many, is applied to paper technology, must carry out fiber process, if the dried slag of blast furnace and other auxiliary material are cooperated high temperature melting in the adding furnace cupola, melt forms dried slag cellucotton through supercentrifuge, more dried slag cellucotton is used its complex manufacturing after softening modification, cost is too high simultaneously, is difficult to promote the use of.Also once had at present with the news report of wollastonite fine powder, but all be in theory stage as part paper pulp substitute.
Summary of the invention
The purpose of this invention is to provide the application of a kind of mineral fibres in paper technology, partly replace paper pulp as paper making raw material, not only saved the paper pulp consumption, and the quality of finished paper improves by adopting the inorganic non-metallic mineral fibres.
The technical solution used in the present invention is as follows:
The application of mineral fibres in paper technology is characterized in that mineral fibres is used as paper making raw material as part paper pulp substitute.
Described mineral fibres is that the microcosmic draw ratio is 10～15: 1 wollastonite mine fine powder.
Described mineral fibres is to add in the pulping operation after pulp preparation as the paper pulp substitute, perhaps with mineral fibres after the sieving removal of impurities, add in the paper pulp simultaneously at header box place and auxiliary agent.
It is 2～40% of paper pulp weight that described mineral fibres adds weight.
The concrete application process of mineral fibres in paper technology is: wood-pulp board or vegetation mixed pulp are when size degradation, the mineral fibres that adds proper proportion, through the pulping operation, mineral fibres and pulp mixture are refining through making beating, kneading again, add then auxiliary agent routinely the technology online manufacture paper with pulp and obtain finished paper.
If the employing straw pulp is a raw material, the application process of mineral fibres is: straw pulp adds the mineral fibres of proper proportion in when making beating, and mineral fibres and pulp mixture pass through the paper pulp refining step again, add then auxiliary agent routinely the technology online manufacture paper with pulp and obtain finished paper.
Another kind of application process is: with the removal of impurities of mineral fibres screening and filtering, add at the header box position, the good paper pulp after adding auxiliary agent and process pulping then and removing the gred mixes, and the technology online is manufactured paper with pulp and obtained finished paper routinely then.
There is abundant wollastonite mineral products resource in China, and explored wollastonite mineral reserve mainly concentrate on ground such as Shanxi, Yunnan, northeast.The main body mineral of wollastonite mine are eakleite, and ore is white in color-canescence, and fracture is glass-pearly luster, the about 2.7g/cm of density
3, hardness is 4.5, SiO in its chemical composition
2Account for 50.8%, CaO accounts for 47%, and other micro substances are the oxide of Al, Fe, Ti, Mn.
These mineral are generally fibrous agrregate, are radial and needle-like.From microcosmic, the infinite chain silicate sturcture that this mineral crystal is joined and forms with drift angle by the Si tetrahedron.Because these silicoglaserite mineral have three groups of cleavage, be parallel to one group of zoon of crystal face, and also constitution system of two groups of cleavage of two directions in addition, be splitting branch, the fibrous condition that provides is provided in the mineral processing.According to the character and the crystal characteristic of wollastonite mineral, peel off auxiliary agent and under uniform temperature and pressure effect, adopt and pressure wink fall technology by interpolation, mineral are processed into fiber rate and the crystal sign that micro mist can also keep mineral simultaneously.Handle if carry out materialization again in crushing process, make the mineral fibres surface have free positive charge, then this mineral fibres easily combines with paper pulp fiber, improves every performance of finished product paper.
In addition, the average whiteness of mineral fibres is about 85%, and the whiteness of high-quality paper pulp also only can reach about 80%, and the adding mineral fibres of appropriateness can effectively increase the whiteness of finished paper, reduces the consumption of brightening agent under the equal conditions.
Beneficial effect of the present invention is; by mineral fibres is used as paper making raw material as the paper pulp substitute; not only saved the paper pulp consumption; reduced the discharge capacity of pulping sewage; preserve the ecological environment; reduce production costs, also improved the drainability of slurry in the process of manufacturing paper with pulp simultaneously, the whiteness of finished paper, antistatic property and tearing toughness all have raising in various degree.
