Papermaking Process PKSC 2010 Exam
1. Three steps of making paper: Pulp Production, Forming/Wet End, Dry End
2. Ingredients of Paper: Pulp, Additives, Water
3. Stock: Pulp that has been beaten/refined, cleaned, and bleached
4. Furnish: Blend of multiple pulps and additives
5. Furnish is: 3-5% water
6. Additives: Binders, fillers, Sizing Agents, and Coloring
7. What % of papermaking cost comes from additives: 10%
8. Binders: Promote and Facilitate fiber to fiber bonding
9. Binders are usually: natural starches and polymers
10. Binders make paper...: stiffer
1/3
, 11. Binders Improve...: Burst, tensile, and folding strength
12. Binders...: reduce water penetratrion
13. Fillers give you...: smoother paper
14. The most common filler is...: white clay
15. Other fillers include...: Titanium Dioxide, Calcium Carbonate, and Talc
16. Internal Sizing Agents...: Improve Liquid Resistance
17. Internal Sizing agents are added to...: furnish (wet end)
18. External sizing agents are added on the...: dry end
19. The most common internal sizing agent is...: rosin
20. Fine particles of rosin....: melt during heating and coat the paper
21. Pigments are and : insoluble, mechanically attatched
