Ubunyulu bepulp bubhekisa kwinqanaba lomxholo we-cellulose kunye nobungakanani bokungcola kwi-pulp. I-pulp efanelekileyo kufuneka ibe ne-cellulose eninzi, ngelixa umxholo we-hemicellulose, i-lignin, uthuthu, izinto ezikhuphayo kunye nezinye izinto ezingezizo ze-cellulose kufuneka ube sezantsi kangangoko. Umxholo we-cellulose umisela ngokuthe ngqo ubunyulu kunye nexabiso lokusebenziseka kwe-pulp, kwaye yenye yezona zinto ziphambili zokuvavanya umgangatho we-pulp. Iimpawu ze-pulp yobunyulu obuphezulu:
(1) ukuqina okuphezulu, i-cellulose yeyona nto iphambili eyenza amandla ephepha, i-pulp ecocekileyo kakhulu ithetha ukuba iqulethe i-cellulose eninzi, ngoko ke iphepha elenziweyo linokumelana nokukrazuka okunamandla, ukumelana nokugoba kunye nezinye iimpawu zomzimba nezoomatshini, nto leyo eyandisa ubomi bephepha.
(2) I-bonding eqinileyo, ii-cellulose fibres ezicocekileyo zinokwenza uthungelwano oludibeneyo phakathi kwephepha ukuze kuphuculwe i-bonding yangaphakathi, ukuze iphepha kungabi lula ukuliqhekeza okanye ukuliqhekeza xa liphantsi kwamandla angaphandle, ukuze kuphuculwe amandla ephepha ngokubanzi.
(3) ukuba mhlophe okuphezulu, ubukho bokungcola budla ngokuchaphazela ubumhlophe kunye nokukhazimla kwephepha. I-pulp ecocekileyo kakhulu, ngenxa yokususwa kobuninzi bokungcola okunemibala, yenza iphepha libonise ubumhlophe bendalo obuphezulu, obufaneleke ngakumbi ekuprinteni, ekubhaleni nasekupakisheni, njl.njl., kwaye buphucula isiphumo sokubonakala kwemveliso.
(4) iipropati zokukhusela umbane ezingcono, i-cellulose ineempawu zokukhusela ezilungileyo, ngelixa izinto ezingezizo ii-cellulose kwi-pulp, ezifana ne-lignin, zinokuba nezinto eziqhubayo okanye ezi-hygroscopic, ezichaphazela ukhuseleko lombane lwephepha. Ke ngoko, iphepha elenziwe nge-pulp ecocekileyo kakhulu linoluhlu olubanzi lwezicelo kubunjineli bombane, njengephepha lokukhusela intambo, iphepha le-capacitor, njl.
Ukulungiswa kwepulp ecocekileyo kakhulu, ishishini lephepha lanamhlanje lisebenzisa iinkqubo ezahlukeneyo eziphambili zepulping, ezifana ne-chemical pulping (kubandakanya i-sulphate pulping, i-sulphite pulping, njl.njl.), i-mechanical pulping (njenge-thermal grinding mechanical pulp TMP) kunye ne-chemical mechanical pulping (CMP) njalo njalo. Ezi nkqubo ziphucula ubunyulu bepulp ngokususa okanye ukuguqula izinto ezingezizo iiseli ze-cellulosic zezinto eziluhlaza.
I-pulp ecocekileyo kakhulu isetyenziswa kakhulu kwiindawo ezininzi ezifana nephepha lenkcubeko elikumgangatho ophezulu, iphepha lokupakisha, iphepha elikhethekileyo (umz., iphepha lokukhusela umbane, iphepha lokucoca, iphepha lezonyango, njl.njl.) kunye nephepha lasekhaya, elihlangabezana nomgangatho ophezulu wephepha ofunekayo kumashishini ahlukeneyo.
Iphepha leYashi lenza kuphela i-100% virgin bamboo pulp, i-single ci bamboo fibre, olulona khetho lufanelekileyo lokucoceka okuphezulu kunye nephepha lasekhaya elikumgangatho ophezulu.
