Definitions
- FIG. 2 is a flow chart describing a mechanical pulping and high yield pulping process for corn stalk pulp.
- FIG. 3 is a flow chart describing a paper making process from corn stalk pulp.
- DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS [0054] Today the paper industry in the United States is in the same situation as steel industry was a few decades ago. Small-scale modern steel industries are more efficient than large-scale facilities. Accordingly, it is time to look for technology for the development of small-scale efficient pulp and paper industry. It is also time to look for inexpensive fiber sources to face the competition from high yield plantation trees such as eucalyptus, acacia, and the like. Agricultural residue such as cornstover can compete with eucalyptus and acacia as an inexpensive source of fiber.
- Screening and cleaning of cornstalk pulp are preferably done before bleaching. This will save bleaching chemicals and improve the bleachability of the pulp.
- the bleached pulp is a mixture of long fiber mainly derived from cornstalk skin and short fiber derived mainly from pith. Refining of this mixture before papermaking will create more fines resulting in a water drainage problem because the fines hold more water than the fiber.
- Short fiber does not need refining, whereas the long fibers might or might not need refining in order to develop bonding properties.
- the bleached fiber should be fractionated into long and short fiber fractions. The long fiber fraction will be refined and then mixed with the short fiber fraction before papermaking.
- the bleached cornstalk pulp is mixed with bleached softwood kraft and/or bleached hardwood kraft pulp for papermaking, the fractionation is not necessary.
- Example 1 The cornstalk portions were separated manually from the leaves and other unwanted materials. The cornstalk stems were then broken into small pieces mechanically. The mechanical separation was accomplished with two oppositely rotating devil teeth plates. The system separates the skin, however, a substantial quantity of pith remains with the skin. It is noted that any other suitable mechanical separating tool may be utilized. [0083] Pulping experiments were conducted using the pith and skin as received from the process. The quantity of pith was about 23 % of total cornstalk except leaves, cones and ears. In a few laboratory scale experiments, the cornstalk skin was separated completely, and in some cases 15 % pith was added to the skin to verify the effects of pith on handsheet properties.
- Note -1 BD-2 (DEDP); Filler 6.6%: Handsheets of grammage 75 g/m 2 , like copy paper, were prepared by using 86.6% cornstalk, 6.6% bleached softwood kraft pulp and 6.6% precipitated calcium carbonate as filler. 20 kg/ton (o.d. basis) of cationic potato starch, 2 kg/ton of AKD sizing agents and cationic and anionic retention aid were used during handsheet making.
- the furnish for the preparation of hardwood paper is as follows: bleached mixed hardwood pulp (commercial grade): 60 %, bleached northern softwood kraft pulp (commercial grade): 20 %; filler (precipitated calcium carbonate): 20 %; starch: 0.5 %; Hercon size 79AKD (0.5 %): 0J %, and Nalco 7520 retention aid (0.1 %): .05 %.
- Hardwood and softwood kraft pulp laps are mixed in a hydrapulper and refined at 3.71 % consistency to 470ml CSF level. Filler and starch are added to machine chest. The Sizing agent and retention aid are metered into the machine chest. The results are presented in Tables 8, 9, 10, and 11. Table 8: Test results of paper made in pilot paper machine.
