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 okuphezulu kwe-cellulose, ngakho-ke iphepha elenziwe linokumelana okunamandla kwezinyembezi, ukumelana nokugoqa nezinye izakhiwo zomzimba nemishini, ukwandisa impilo yesevisi iphepha.
(2) Ukuhlanganiswa okuqinile, imicu ye-cellulose emsulwa ingakha inethiwekhi exhumene eduze phakathi kwephepha ukuze kuthuthukiswe ukuhlangana kwangaphakathi, ukuze iphepha lingabi lula ukuchithwa noma ukuphulwa lapho lingaphansi kwamandla 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 pulping (CMP). ) njalo njalo. Lezi zinqubo zithuthukisa ukuhlanzeka kwe-pulp ngokususa noma ukuguqula izingxenye ze-non-cellulosic zempahla eluhlaza.
I-high purity pulp isetshenziswa kabanzi emikhakheni eminingi efana nephepha lesikompilo lezinga eliphezulu, iphepha lokupakisha, iphepha elikhethekile (isb., iphepha lokufakwa kukagesi, iphepha lokuhlunga, iphepha lezokwelapha, njll.) kanye nephepha lasendlini, elihlangabezana nezinga eliphezulu lekhwalithi yephepha. kudingwa yizimboni 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.
