Impembelelo yemo yefayibha kwiipropati zepulp kunye nomgangatho wayo

Kwishishini lephepha, imo yefayibha yenye yezinto eziphambili ezichaza iipropati zepulp kunye nomgangatho wokugqibela wephepha. Imo yefayibha ibandakanya ubude obuqhelekileyo beefayibha, umlinganiselo wobukhulu bodonga lweseli yefayibha ukuya kububanzi beseli (ebizwa ngokuba yi-wall-to-cavity ratio), kunye nobungakanani bee-heterocytes ezingezizo iifayibha kunye nee-fibre bundles kwipulp. Ezi zinto ziyasebenzisana, kwaye zichaphazela amandla okubopha kwepulp, ukusebenza kakuhle kokuphelelwa ngamanzi emzimbeni, ukusebenza kokukopa, kunye namandla, ukuqina kunye nomgangatho uwonke wephepha.

1) Ubude obuqhelekileyo befayibha
Ubude obuqhelekileyo beefayibha yenye yezona zinto zibalulekileyo ezibonisa umgangatho we-pulp. Iifayibha ezinde zenza imixokelelwane yenethiwekhi emide kwi-pulp, nto leyo enceda ekuphuculeni amandla okubopha kunye neempawu zokuxinana kwephepha. Xa ubude obuqhelekileyo beefayibha busanda, inani lamanqaku adibeneyo phakathi kweefayibha liyakhula, okuvumela iphepha ukuba lisasaze ngcono uxinzelelo xa liphantsi kwamandla angaphandle, ngaloo ndlela liphucula amandla kunye nokuqina kwephepha. Ke ngoko, ukusetyenziswa kweefayibha ezinde ezinde, ezifana ne-spruce coniferous pulp okanye i-cotton kunye ne-linen pulp, kunokuvelisa amandla aphezulu, ukuqina okungcono kwephepha, la maphepha afaneleke ngakumbi ukusetyenziswa kwisidingo seempawu zomzimba eziphezulu zesiganeko, ezifana nezinto zokupakisha, iphepha lokuprinta njalo njalo.
2) Umlinganiselo wobukhulu bodonga lwe-fiber cell ukuya kububanzi bomngxuma weseli (umlinganiselo wodonga ukuya kumngxuma)
Umlinganiselo wodonga ukuya kumgodi yenye into ebalulekileyo echaphazela iipropati zepulp. Umlinganiselo ophantsi wodonga ukuya kumgodi uthetha ukuba udonga lweseli yefayibha lubhityile kwaye umngxuma weseli mkhulu, ukuze iifayibha kwinkqubo yokugaya kunye nokwenza iphepha kube lula ukufunxa amanzi nokuthamba, okunceda ukucocwa kweefayibha, ukusasazwa kunye nokudibana. Kwangaxeshanye, iifayibha ezinodonga olubhityileyo zibonelela ngokuguquguquka okungcono kunye nokugobeka xa kusenziwa iphepha, okwenza iphepha lifaneleke ngakumbi kwiinkqubo ezinzima zokucubungula nokwenza. Ngokwahlukileyo koko, iifayibha ezinomlinganiselo ophezulu wodonga ukuya kumgodi zinokukhokelela kwiphepha eliqinileyo kakhulu, elibuthathaka, elingafanelekiyo ekucutshungulweni nasekusetyenzisweni okulandelayo.
3) Umxholo wee-heterocytes ezingezizo iifayibha kunye neefayibha ezihlanganisiweyo
Iiseli ezingezizo iifayibha kunye neefayibha ezikwipulp zizinto ezimbi ezichaphazela umgangatho wephepha. Ezi ngcola aziyi kunciphisa kuphela ubunyulu kunye nokufana kwepulp, kodwa nakwinkqubo yokwenza iphepha ukuze zenze amaqhina kunye neziphene, okuchaphazela ukuguda kunye namandla ephepha. Ii-heterocytes ezingezizo iifayibha zinokuvela kwizinto ezingezizo iifayibha ezifana nexolo, i-resin kunye neentsini kwizinto eziluhlaza, ngelixa iifayibha zizinto ezihlanganisiweyo ezenziwe ngenxa yokungaphumeleli kwezinto eziluhlaza ukwahlukana ngokwaneleyo ngexesha lenkqubo yokulungiselela. Ke ngoko, ezi ngcola kufuneka zisuswe kangangoko kunokwenzeka ngexesha lenkqubo yokugaya ukuze kuphuculwe umgangatho wepulp kunye nemveliso yephepha.
