Ndi zinthu ziti zomwe zimakhudza kuchuluka kwa mapepala?

Mzaka zaposachedwa,opanga mapepalandipo ogwiritsa ntchito apereka chidwi kwambiri pazambiri za pepala, chifukwa chochuluka chimakhudza kwambiri mtengo ndi ntchito ya mankhwala.Kuchuluka kwakukulu kumatanthawuza kuti pa makulidwe omwewo, kulemera kwa maziko kungathe kuchepetsedwa, ndipo kuchuluka kwa ulusi wogwiritsidwa ntchito kungathe kuchepetsedwa kuti akwaniritse ndalama;kuchulukirachulukira kumatha kukulitsa kuuma kwa mapepala, kulola osindikiza mabuku kukhalabe makulidwe athunthu abuku ndi masamba ochepa, komanso kutha kukulitsa mawonekedwe a pepala, kusindikizidwa, ndikuchepetsa kutulutsa kwa inki yosindikiza.Chifukwa chake, kuchuluka kwakukulu kumakhala kofunikira kwambiri pakuwongolera mtengo wa pepala, magwiridwe antchito komanso mtengo wowonjezera wazinthu.

Kodi kuchuluka kwakukulu ndi chiyani?Ichi ndi chizindikiro chofunikira cha pepala, chomwe ndi chiŵerengero cha kulemera kwa maziko ndi makulidwe.Chochuluka chimasonyeza kachulukidwe ka pepala, ndiko kuti, kukula kwa porosity ya pepala.

Zinthu zazikulu zomwe zimakhudza kuchuluka kwa mapepala ndi kuphatikiza zida zopangira mapepala, mtundu wa zamkati, kumenya, zodzaza, mankhwala, kukanikiza, kuyanika, kalendala, etc.

Fiber morphology of the papermaking fiber raw material imakhala ndi chikoka pazambiri zamapepala.Ulusi wokhuthala uli ndi porosity yapamwamba komanso mapepala apamwamba, koma zambiri sizimangokhudzana ndi makulidwe a fiber, komanso zimakhala ndi ubale wofunikira kwambiri ndi kuphwanya kwa ulusi panthawi yopanga mapepala.Pamapeto pake zimatengera kuchuluka kwa kuphwanya ndi kusinthika kwa ulusi.Chifukwa chake, ulusi wokhala ndi mainchesi ang'onoang'ono ndi makoma okhuthala ndi olimba, osavuta kuphwanyidwa, komanso osavuta kupanga mapepala ochuluka.
PAPER RAW MATERIAL

Mtundu wa zamkati umakhalanso ndi chikoka chachikulu pazambiri za pepala.Nthawi zambiri, zokolola zambiri zamkati> thermomechanical zamkati> kraft zamkati> zinyalala zamkati.Zopangira zosiyanasiyana zimakhala ndi kuchuluka kosiyana mu zamkati zomwezo, nkhuni zolimba> zofewa.Thechochulukazamkati zokolola zambiri sizingafanane ndi zamkati zina, kotero zamkati zokolola zambiri zimagwiritsidwa ntchito kwambiri m'malo mwa zamkati za bleached kraft hardwood pamapepala apamwamba.Kusankhidwa ndi chiŵerengero cha mitundu ya zamkati ndiye chinsinsi cha ndondomeko yamakono yopangira mapepala ambiri.Kuonjezera zokolola zambiri kuti mapepala ambiri apangidwe ndi njira yabwino kwambiri yomwe imagwiritsidwa ntchito kwambiri ndi mphero zamapepala.
pepala la pepala

Kuchuluka ndi chinthu chofunika kwambiri cha pepala.Zochuluka kwambirimapepala amatha kukhala owuma kofunikira, kuchepetsa kugwiritsa ntchito ulusi, kupulumutsa ndalama zamkati, ndikuwongolera zambiri.Njira zothekera kwambiri pakadali pano zikuphatikiza kuwonjezera zokolola zambiri, kusankha zamkati ndi machitidwe opangira.Kukhathamiritsa ndi kupanga zowonjezera zatsopano zambiri ndizofunikiranso pakufufuza.
