Igipimo cyo Kwibanda
Ubunini bwa pulp mu gituza cyimashini bugera kuri 2,5-3,5% muri rusange. Amazi arasabwa kugabanya ifu kugirango igabanuke kugirango fibre ikwirakwijwe neza no kuvanaho umwanda.
Kuriimashini zine, ifumbire yibanze yinjira muri mesh ni 0.3-1.0% mubisanzwe ukurikije imiterere ya pulp, imiterere yibikoresho, hamwe nubwiza bwimpapuro. Kuri iki cyiciro, urwego rwo guhindagurika ruhuye nibisabwa bya pulp kuri mesh, bivuze ko icyerekezo kimwe gikoreshwa mugusukura, kuyungurura, no gukora kuri mesh.
Imbuto yibanze kuri mesh iri munsi ya 0.1–0.3% kumashini ya silinderi gusa. Igipimo cyo gutembera binyuze mu kweza no kuyungurura kiri hejuru y'ibisabwa hamwe na pulp-concentration nkeya. Byongeye kandi, ibikoresho byinshi byo kweza no kuyungurura birakenewe kugirango habeho gutunganya imbaraga nkeya, bisaba igishoro kinini, umwanya munini, imiyoboro igoye, hamwe n’ingufu nyinshi.
Imashini ya silinderi akenshi ifata aibyiciro bibiri,aho kwibanda kumanuka kugera kuri 0.5 ~ 0,6% ubanza kugirango bisukure mbere kandi byungururwe; hanyuma umanurwe kugirango ugere kumurongo mbere yo kwinjira kuri mesh mugutuza agasanduku.
Amashanyarazi akoresha amazi yera binyuze muri mesh muburyo busanzwe bwo kubungabunga amazi no kugarura fibre nziza, kuzuza, hamwe n’imiti ivuye mumazi yera. Kugarura amazi yera ninyungu zo kubungabunga ingufu kumashini zisaba gushyuha.
Ibintu by'ingenzi bigira ingaruka ku guhunika kwa pulp
Guhindagurika muburyo bwa Pulp Kwinjiza Kwinjiza Agasanduku
Imihindagurikire ihamye kuva gukubitwa cyangwa guhinduka muri sisitemu yamenetse birashobora gutera itandukaniro mubitekerezo bya pulp. Kuzenguruka nabi mu gatuza k'imashini birashobora gutuma habaho guhuzagurika kwa pulp mu bice bitandukanye, bigatera umutekano muke.
Gusubira inyuma kwangwas inKwezwa nokuyungurura
Kwanga kwezwa no kuyungurura mubisanzwe byongeye kwinjizwa muri sisitemu n'amazi yo kuyungurura. Guhindagurika mubunini no kwibanda kuri uku kwanga biterwa nigikorwa cyibikoresho byo kweza no kuyungurura hamwe nurwego rwamazi kuri pompe.
Izi mpinduka zitanga ingaruka kumazi yera akoreshwa mukuyungurura, hanyuma, nubuso bwanyuma bwa pulp. Ibibazo nkibi birashobora kugaragara muri sisitemu yo kugaruka ya mashini ya silinderi yuzuye.
Guhindagurika muburyo bwa pulp yibanze bishobora kugira ingaruka kumikorere yimashini yimpapuro hamwe nubwiza bwimpapuro zanyuma. Kubwibyo, ni ngombwa gukurikiranira hafi pulp yibanze hamweuburebure bwa metero pulpbyakozwe naLonnmetermugihe cyo kubyara no guhindura ibyinjira mubisanduku bigenzura kugirango ugumane ibitekerezo bihamye. Imashini zimpapuro zigezweho zikoresha ibikoresho byikora kuri:
- Hindura mu buryo bwikorakwibandakwinjiza agasanduku.
- Hindura urujya n'uruza rushingiye ku mpinduka zishingiye ku mpapuro uburemere kandiAgasanduku k'umutwe.
Ibi bituma impagarike ihamye.
Inyungu zo Guhindura Ibitekerezo Guhindura Amashanyarazi
Kwishyira hamwe kugabanura inyungu zunguka kubikorwa byombi byimashini yimpapuro hamwe no kubungabunga ubuziranenge bwimpapuro.
Kumashini ya Cylinder
Iyo ifu ifite urugero rwo gukubita no gutemba vuba vuba, amazi yimbere nayandi yo hanze mugice cya mesh aragabanuka, bikagabanya kwizirika kumpapuro. Ibi byongera ingaruka yibitekerezo, bigabanya umuvuduko mwinshi, kandi byongera itandukaniro ryihuta hagati ya pulp na mesh, biganisha kumpapuro zidahwanye.
Kugira ngo iki kibazo gikemuke, gukoresha amazi yera byongerewe kugirango ugabanye imbaraga, byongera umuvuduko wa mesh. Ibi bizamura urwego rwamazi atandukanye, byongera umuvuduko mwinshi, bigabanya ingaruka ziterwa no kwibanda, kandi bigabanya itandukaniro ryihuta, bityo bitezimbere impapuro.
Kumashini ya Fourdrinier
Impamyabumenyi nyinshi yo gukubita ituma amazi atemba, kwagura umurongo wamazi, kongera ubushuhe mumpapuro zitose, kandi biganisha ku gushushanya cyangwa kumenagura mugihe cyo gukanda. Impagarike yimpapuro hejuru ya mashini iragabanuka, no kugabanuka mugihe cyo kumisha byiyongera, bigatera inenge nkubunini n'iminkanyari.
Kugira ngo ukemure izo mbogamizi, kwibumbira hamwe bishobora kugabanuka mugukoresha amazi yera, kugabanya ibibazo byamazi.
Ibinyuranye, niba urwego rwo gukubita ruri hasi, fibre ikunda guhindagurika, kandi amazi atemba vuba vuba kuri mesh, bikagira ingaruka kumpapuro. Muri iki gihe, kongera amazi yera kugirango ugabanye umuvuduko wa pulp urashobora kugabanya flokculation no kunoza uburinganire.
Umwanzuro
Gukoresha nigikorwa gikomeye mugukora impapuro. Mu musaruro, ni ngombwa kuri:
- Gukurikiranira hafi no kugenzura byimazeyo impinduka zivanzekwibandakwemeza ibikorwa bihamye.
- Witondere impinduka mubicuruzwa byiza nibikorwakandi, nibiba ngombwa, hindura kwibanda kuri pulp nkigikoresho cyo gutsinda ingorane nkizo zavuzwe haruguru.
Mugucunga neza impanuka ya pulp, umusaruro uhamye, impapuro zujuje ubuziranenge, nibikorwa byiza birashobora kugerwaho.
