Abstract
The invention relates to a papermaking process flow for recycling waste newspaper and magazines, belonging to the papermaking technology field, in particular to a papermaking process flow for recycling waste newspaper and magazines; in the invention, the waste newspaper and magazines are recycled by paper sorting, waste paper water granulation, screening, washing and blanching, internal starching and papermaking procedures. The method can effectively recycle the waste newspaper and magazines, and the quality of the manufactured finished paper is accord with requirements; the cost is reduced and the energy is saved, thereby radically solving the paper regeneration technology and having remarkable social and economic benefits.
Description
Technical field:
The invention belongs to pulp technology for making paper, especially relate to the papermaking process flow that a kind of waste newspaper and magazines is recycled.
Background technology:
The whole nation will produce a large amount of disregard message paper and magazine every year, if do not recycle, not only contaminated environment also can cause the waste of resource.
Summary of the invention:
The invention provides a kind of paper technology method of recycling waste newspaper and magazines.
The present invention is achieved by the following technical solution: the papermaking process flow that a kind of waste newspaper and magazines is recycled is characterized in that its step:
1, sorter preface:
2, the broken operation of waste paper water: earlier wastepaper≤60%, books and periodicals magazine≤30%, assorted paper foreign material≤0.5% mixes the mechanical size degradation in back, handle with the DEINKING CHEMICALS deinking then, printing ink impurity on the separating pulp fiber is removed thick foreign material in the paper pulp, the balance paper pulp brightness;
3, screening process: utilize pressure screening, cleaning equipment that proportion difference and particle size, ink particle, sicker and other impurity that granularity is bigger are separated from slurry;
4, wash and float operation: flotation before and after utilizing, washing facility are separated tiny ink particle and sicker in the slurry from slurry;
5, starch in the slurry: in slurry, add neutral sizing starch
6, surface sizing starch
7, add the retention agent operation
8, filler operation
9, papermaking operation: comprising: online, squeezing, drying, top sizing, press polish, batch, the rewinding operation.
The present invention can recycle obsolete waste newspaper and magazines effectively, and the manufactured finished paper amount meets the requirements.Reduce cost, energy savings has fundamentally solved paper industry regeneration techniques, has significant social and economic benefit.
The specific embodiment:
The paper technology that this waste newspaper and magazines is recycled: at first be the sorter preface: boxboard, brown paper, playing card paper, two sides gummed paper are selected, made wastepaper≤60%, books and periodicals magazine≤30%, assorted paper foreign material≤0.5%;
Two, the broken operation of waste paper water: wastepaper≤60%, books and periodicals magazine≤30%, assorted paper foreign material≤0.5% is by the high-concentration pulper size degradation, every cylinder paper (air-dry) 2.5-2.7 ton, 65-70 ℃ of hot plain boiled water temperature, 7 cubic metres of pulping plain boiled water consumptions, pulping concentration is 15-17%; Put into the DEINKING CHEMICALS deinking then and handle, liquid caustic soda 0.95%, waterglass 2.2%, chelating agent 0.2%, deinking agent 0.5-0.788%, hydrogen peroxide 1.85% enters brown stock chest by coarse classifier then.
Three, screening process: proportion difference and particle size, ink particle, sicker and other impurity that granularity is bigger are separated from slurry by HC Cleaner, oscillating flat sieve, pressure hole sizer, slotted screen.Floatation concentration 0.9-1.1% send the slurry dirt count: (fiber) 0.5-1.5m m
2≤ 10/gram, 1.5-2.5m m
2≤ 3/gram 2.5m m
2More than≤0; Send the slurry sicker: big 0.05-0.1m m
2≤ 15/gram, middle 0.1-0.2mm
2≤ 2/gram, 0.2m m
2More than≤0/gram.
Four, wash and float operation: utilize totally-enclosed floatation and ink removing machine, high-speed pulp washer, bleached pulp tower that tiny ink particle and sicker in the slurry are separated from slurry, send pulp brightness, high white 58-61%, pure white 59-62%; Send slurry pH value 7-8; Send the slurry sicker little/in/be faced with imminent disaster 5/2/0.
Five, finish pulping process by high-speed pulp washer and refining operation: guarantee the refining quality by high-speed pulp washer, double plate mill, pump, agitator.
Six, enter the papermaking operation: by starching interior starch: adding neutral sizing starch, surface sizing starch, interpolation retention agent, bactericide operation, filler operation, online, squeezing, drying, top sizing, press polish in slurry, batch, the rewinding operation is formed into product paper.
