Mhedzisiro yechimiro chefiber pahunhu hwepulp uye kunaka kwayo

Muindasitiri yemapepa, chimiro chefiber ndechimwe chezvinhu zvikuru zvinosarudza hunhu hwepulp uye kunaka kwepepa rekupedzisira. Chimiro chefiber chinosanganisira avhareji yehurefu hwefibers, chiyero chekukora kwemadziro efiber cell nedhayamita yesero (chinonzi chiyero chemadziro-kune-cavity), uye huwandu hwemaheterocytes asina fibrous uye mabhurugwa efiber mupulp. Zvinhu izvi zvinodyidzana, uye zvinokanganisa pamwe chete simba rekubatana kwepulp, kushanda zvakanaka kwemvura, kushanda kwekukopa, pamwe nesimba, kuomarara uye kunaka kwepepa.

1) Avhareji yehurefu hwefaibha
Avhareji yehurefu hwemafiber ndeimwe yezviratidzo zvakakosha zvemhando yepulp. Mafiber marefu anoumba cheni refu dzenetwork mupulp, izvo zvinobatsira kuwedzera simba rekubatanidza uye hunhu hwekusunga bepa. Kana avhareji yehurefu hwemafiber ikawedzera, huwandu hwenzvimbo dzakarukwa pakati pemafiber hunowedzera, zvichibvumira bepa kuparadzira zviri nani kushushikana kana richinge rabatwa nemasimba ekunze, nokudaro zvichivandudza simba uye kusimba kwebepa. Nokudaro, kushandiswa kwemafiber marefu ehurefu, akadai sespruce coniferous pulp kana donje nelinen pulp, kunogona kuburitsa simba rakawanda, kusimba kuri nani kwebepa, mapepa aya akakodzera kushandiswa mukuda kwezvinhu zvepamusoro zvemuviri zvechiitiko ichi, zvakaita sezvinhu zvekurongedza, bepa rekudhinda nezvimwewo.
2) Chiyero cheukobvu hwemadziro efaibha nedhayamita yemukati mesero (chiyero chemadziro nemukati mesero)
Chiyero chemadziro negomba chimwe chinhu chakakosha chinokanganisa hunhu hwepulp. Chiyero chemadziro negomba chakaderera chinoreva kuti madziro esero efiber akatetepa uye gomba resero rakakura, kuitira kuti fiber dziri mu pulping nekugadzira mapepa zvive nyore kunyudza mvura nekunyorova, zvichibatsira kunatswa kwemafiber, kupararira uye kubatana. Panguva imwe chete, fibers dzakatetepa dzinopa kuchinjika kuri nani uye kupetwa zviri nani pakuumba bepa, zvichiita kuti bepa rive rakakodzera kugadziriswa kwakaoma uye maitiro ekuumba. Kusiyana neizvi, fibers dzine ratios dzakakwirira dzemadziro negomba dzinogona kutungamira kune bepa rakaoma kwazvo, rinopwanyika, izvo zvisingakodzeri kugadziriswa nekushandiswa gare gare.
3) Zviri mukati memasero eheterocyte asina fibrous uye mafibre bundles
Masero asina fibrous uye mafibre bundles ari mu pulp zvinhu zvakaipa zvinokanganisa kunaka kwepepa. Kusachena uku hakungoderedzi kuchena uye kufanana kwe pulp chete, asiwo mukugadzira mapepa kuti agadzire mapfundo uye zvikanganiso, zvichikanganisa kutsvedzerera uye kusimba kwepepa. Ma heterocytes asina fibrous anogona kubva muzvinhu zvisina fibrous zvakaita semakwati, resin uye gums muzvinhu zvakagadziriswa, nepo ma fibre bundles ari ma fiber aggregates akaumbwa nekuda kwekutadza kwechinhu chisina kugadzirwa kupatsanurwa zvakakwana panguva yekugadzirira. Nokudaro, kusachena uku kunofanira kubviswa zvakanyanya panguva ye pulping kuti kunatsiridze kunaka kwe pulp uye kubereka kwepepa.
