Ukuhlanzeka kwe-pulp kubhekisela ezingeni lokuqukethwe kwe-cellulose kanye nenani lokungcola ku-pulp. I-pulp efanelekile kufanele ibe ne-cellulose ecebile, kuyilapho okuqukethwe kwe-hemicellulose, i-lignin, umlotha, i-extractives nezinye izingxenye ezingezona i-cellulose kufanele kube phansi ngangokunokwenzeka. Okuqukethwe kwe-cellulose kunquma ngokuqondile ubumsulwa kanye nevelu yokusebenziseka ye-pulp, futhi ingenye yezinkomba eziyinhloko zokuhlola ikhwalithi ye-pulp. Izici zokuhlanzeka okuphezulu kwe-pulp:
(1) ukuqina okuphezulu, i-cellulose iyingxenye eyinhloko ehlanganisa amandla ephepha, ukuhlanzeka okuphezulu kwe-pulp kusho okuqukethwe kwe-cellulose ephakeme, ngakho-ke iphepha elenziwe linokumelana okunamandla kwezinyembezi, ukumelana nokugoqa nezinye izakhiwo ezingokomzimba nezomshini, okunweba impilo yesevisi yephepha.
(2) Ukuhlanganiswa okuqinile, imicu ye-cellulose ehlanzekile ingakha inethiwekhi ehlanganisiwe esondelene phakathi kwephepha ukuze kuthuthukiswe ukuhlangana kwangaphakathi, ukuze iphepha lingabi lula ukuchithwa noma ukuphulwa lapho libhekene namandla angaphandle, ukuthuthukisa amandla onke ephepha.
(3) ubumhlophe obuphakeme, ukuba khona kokungcola kuvame ukuthinta ubumhlophe nokucwebezela kwephepha. I-pulp yokuhlanzeka okuphezulu, ngenxa yokukhishwa kokungcola okuningi okunemibala, yenza iphepha libonise ubumhlophe bemvelo obuphezulu, obufaneleka kakhulu ukuphrinta, ukubhala nokupakisha, njll, futhi kuthuthukise umphumela wokubukwa komkhiqizo.
(4) izici ezingcono zokuvala ugesi, i-cellulose inezinto ezinhle zokuvikela ugesi, kuyilapho izingxenye ezingezona i-cellulose ku-pulp, njenge-lignin, zingaqukatha izinto ezibambayo noma ze-hygroscopic, ezithinta ukufakwa kukagesi ephepheni. Ngakho-ke, iphepha elenziwe kusuka ku-high-purity pulp linezinhlobonhlobo zezinhlelo zokusebenza kwezobunjiniyela kagesi, njengephepha le-cable insulation, iphepha le-capacitor, njll.
Ukulungiswa kwe-pulp yokuhlanzeka okuphezulu, imboni yamaphepha yesimanje isebenzisa izinqubo ezithuthukisiwe ze-pulping, ezifana ne-chemical pulping (okuhlanganisa i-sulphate pulping, i-sulphite pulping, njll.), i-pulping mechanical (njenge-thermal grinding mechanical pulp TMP) kanye ne-chemical pulping mechanical (CMP) nokunye. Lezi zinqubo zithuthukisa ukuhlanzeka kwe-pulp ngokususa noma ukuguqula izingxenye ze-non-cellulosic zempahla eluhlaza.
I-pulp yokuhlanzeka okuphezulu isetshenziswa kakhulu emikhakheni eminingi efana nephepha lesiko lezinga eliphezulu, iphepha lokupakisha, iphepha elikhethekile (isb., iphepha lokufaka ugesi kagesi, iphepha lokuhlunga, iphepha lezokwelapha, njll.) kanye nephepha lasendlini, elihlangabezana nezinga eliphezulu lekhwalithi yephepha elidingwa izimboni ezahlukene.
Iphepha le-Yashi lenza kuphela u-100% we-bamboo pulp, i-ci bamboo fiber eyodwa, okuyisinqumo esingcono kakhulu sokuhlanzeka okuphezulu kanye nephepha lasendlini lekhwalithi ephezulu.
