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 lelona candelo liquka ukomelela kwephepha, ukucoceka okuphezulu kwe-pulp kuthetha umxholo weselulosi ephezulu, ngoko ke iphepha lenziwe linamandla okuxhathisa ukukrazula, ukuxhathisa ukusonga kunye nezinye iimpawu zomzimba kunye noomatshini, ukwandisa ubomi benkonzo iphepha.
(2) Ukudibanisa okunamandla, imicu ye-cellulose ecocekileyo inokwenza uthungelwano olusondeleyo phakathi kwephepha ukuze kuphuculwe ukudibanisa kwangaphakathi, ukuze iphepha lingabi lula ukuba lihlanjululwe okanye liphulwe xa lixhomekeke kumandla angaphandle, ukuphucula 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 ephezulu yokucoceka, ishishini lephepha lanamhlanje lisebenzisa iinkqubo ezahlukeneyo zokucofa, ezifana ne-chemical pulping (kubandakanya i-sulphate pulping, i-sulphite pulping, njl. njl.), i-pulping mechanical (efana ne-thermal grinding mechanical pulp TMP) kunye ne-chemical pulping pulping (CMP). ) kwaye nangokunjalo. Ezi nkqubo ziphucula ukucoceka kwe-pulp ngokususa okanye ukuguqula amacandelo angenayo i-cellulosic yezinto eziluhlaza.
I-pulp yococeko oluphezulu lusetyenziswa ngokubanzi kwiinkalo ezininzi ezifana nephepha eliphezulu lenkcubeko, iphepha lokupakisha, iphepha elikhethekileyo (umzekelo, iphepha lokugquma umbane, iphepha lokucoca, iphepha lezonyango, njl. ezifunwa ngamashishini ahlukeneyo.
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.
