Impembelelo ye-fiber morphology kwiipropati ze-pulp kunye nomgangatho

Kwishishini lephepha, i-fiber morphology yenye yezinto eziphambili ezimisela iimpawu ze-pulp kunye nomgangatho wephepha lokugqibela. I-Fiber morphology ibandakanya ubude obuqhelekileyo be-fibers, umlinganiselo we-fiber cell wall thickness to cell diameter (ebizwa ngokuba yi-wall-to-cavity ratio), kunye nenani le-heterocytes engekho-fibrous kunye ne-fiber bundles kwi-pulp. Ezi zinto zisebenzisana kunye, kwaye zichaphazela ngokudibeneyo amandla ebhondi ye-pulp, ukusebenza kakuhle kwamanzi, ukukopisha ukusebenza, kunye namandla, ukuqina kunye nomgangatho jikelele wephepha.

1) I-avareji yobude befiber
Umyinge wobude bemicu sesinye sezibonakaliso ezibalulekileyo zomgangatho wepulp. Iintsinga ezinde zenza imixokelelwane emide yothungelwano kwipulp, enceda ukomeleza amandla ebhondi kunye neepropathi eziqinileyo zephepha. Xa umyinge wobude beefayili zanda, inani lamaphuzu adibeneyo phakathi kweefayili liyenyuka, livumela iphepha ukuba lisasazeke kakuhle uxinzelelo xa lixhomekeke kumandla angaphandle, ngaloo ndlela kuphuculwe amandla kunye nokuqina kwephepha. Ke ngoko, ukusetyenziswa kweefibers zobude obude, ezinje ngespruce coniferous pulp okanye umqhaphu kunye nelinen pulp, kunokuvelisa amandla aphezulu, ukuqina okungcono kwephepha, la maphepha afaneleke ngakumbi ukusetyenziswa kwimfuno yeempawu eziphezulu zeso sihlandlo, njengezinto zokupakisha, iphepha lokushicilela njalo njalo.

Umlinganiselo wodonga ukuya kwi-cavity yenye into ebalulekileyo echaphazela iipropati ze-pulp. Umlinganiselo osezantsi wodonga-kwi-cavity uthetha ukuba udonga lweseli yefiber luncinci kwaye i-cell cavity inkulu, ukuze imicu ye-pulping kunye ne-papermaking ibe lula ukufunxa amanzi kwaye ithambe, inceda ukucocwa kweentsinga, ukusabalalisa. kunye nokuhlangana. Ngelo xesha, iifiber ezinodonga oluncinci zibonelela ngokuguquguquka okungcono kunye nokugotywa xa kusenziwa iphepha, okwenza iphepha lifaneleke ngakumbi kwiinkqubo eziyinkimbinkimbi kunye nokwenziwa. Ngokwahlukileyo, iifiber ezinodonga oluphezulu ukuya kwi-cavity ratios zingakhokelela kubunzima obugqithisileyo, iphepha elinqabileyo, elingenakulungele ukusetyenzwa kunye nokusetyenziswa okulandelayo.
3) Umxholo wee-heterocytes ezingenayo i-fibrous kunye ne-fiber bundles
Iiseli ezingenayo i-fibrous kunye ne-fiber bundles kwi-pulp zizinto ezimbi ezichaphazela umgangatho wephepha. Oku kungcola akuyi kunciphisa kuphela ukucoceka kunye nokufana kwe-pulp, kodwa nakwinkqubo yokwenza iphepha ukwenza amaqhina kunye neziphene, ezichaphazela ukuguquguquka kunye namandla ephepha. I-heterocytes engekho-fibrous inokuvela kumacandelo angenayo i-fibrous efana ne-bark, i-resin kunye neentsini kwi-raw material, ngelixa i-fiber bundles i-fiber aggregates eyenziwe ngenxa yokungaphumeleli kwezinto eziluhlaza ukuhlukana ngokwaneleyo ngexesha lokulungiselela inkqubo. Ngoko ke, oku kungcola kufuneka kususwe kangangoko kunokwenzeka ngexesha lenkqubo ye-pulping ukuphucula umgangatho we-pulp kunye nesivuno sephepha.
