Ukucoceka kwe-Pulp kubhekisela kwinqanaba le-cellulose umxholo kunye nobuninzi bokungcola kwi-pulp. I-pulp efanelekileyo kufuneka ibe sisityebi kwi-cellulose, ngelixa umxholo we-hemicellulose, i-lignin, umlotha, i-extractives kunye nezinye izinto ezingenayo i-cellulose kufuneka zibe ziphantsi kangangoko kunokwenzeka. Umxholo we-cellulose unquma ngokuthe ngqo ukucoceka kunye nokusebenziseka kwexabiso le-pulp, kwaye sesinye sezibonakaliso eziphambili zokuvavanya umgangatho we-pulp. Iimpawu zokucoceka okuphezulu kwepulp:
(1) ukuqina okuphezulu, i-cellulose licandelo eliphambili elibandakanya amandla ephepha, i-pulp yococeko ephezulu ithetha umxholo weselulosi ephezulu, ngoko ke iphepha lenziwe linamandla okuxhathisa ukukrazula, ukuxhathisa ukusonga kunye nezinye iimpawu zomzimba kunye noomatshini, ukwandisa ubomi benkonzo yephepha.
(2) Ukudibanisa okunamandla, iifayili ze-cellulose ezicocekileyo zingenza inethiwekhi edibeneyo edibeneyo phakathi kwephepha ukuze kuphuculwe ukudibanisa kwangaphakathi, ukwenzela ukuba iphepha lingabi lula ukuba lihlanjululwe okanye liphulwe xa lixhomekeke kumandla angaphandle, ukunyusa amandla onke ephepha.
(3) ubumhlophe obuphezulu, ubukho bokungcola buhlala buchaphazela ubumhlophe kunye neglosi yephepha. I-pulp yokucoceka okuphezulu, ngenxa yokususwa kwezinto ezininzi ezingcolileyo ezinemibala, yenza iphepha libonise ubumhlophe bendalo obuphezulu, obufaneleke ngakumbi ukuprinta, ukubhala kunye nokupakishwa, njl., kwaye kuphuculwe umphumo obonakalayo wemveliso.
(4) iipropati ezingcono zokugquma umbane, i-cellulose ineempawu ezintle zokugquma, ngelixa amacandelo angenayo i-cellulose kwi-pulp, njenge-lignin, ingaba nezinto eziqhubayo okanye ze-hygroscopic, ezichaphazela ukugquma kombane kwephepha. Ngoko ke, iphepha elenziwe kwi-pulp yococeko oluphezulu lunoluhlu olubanzi lwezicelo kubunjineli bombane, njengephepha le-cable insulation, iphepha le-capacitor, njl.
Ukulungiswa kwe-pulp yokucoceka okuphezulu, ishishini lephepha lanamhlanje lisebenzisa iinkqubo ezahlukeneyo ze-pulping eziphambili, ezifana ne-chemical pulping (kubandakanywa ne-sulphate pulping, i-sulphite pulping, njl.), I-pulping mechanical (njenge-thermal grinding mechanical pulp TMP) kunye ne-chemical pulping pulping (CMP) njalo njalo. Ezi nkqubo ziphucula ukucoceka kwe-pulp ngokususa okanye ukuguqula amacandelo angenayo i-cellulosic yezinto eziluhlaza.
I-pulp yokucoceka okuphezulu isetyenziswa ngokubanzi kwiinkalo ezininzi ezifana nephepha lenkcubeko ephezulu, iphepha lokupakisha, iphepha elikhethekileyo (umzekelo, iphepha lokufakelwa kombane, iphepha lokucoca, iphepha lezonyango, njl.
Iphepha le-Yashi lenza kuphela i-100% ye-bamboo pulp enyulu, i-ci bamboo fiber enye, lolona khetho lulungileyo lokucoceka okuphezulu kunye nephepha lekhaya elikumgangatho ophezulu.
