Pampiri ea Kraft e bōpiloe ka mokhoa oa vulcanization, o tiisang hore pampiri ea kraft e loketse ka ho feletseng bakeng sa tšebeliso ea eona e reriloeng. Ka lebaka la litekanyetso tse ntseng li eketseha tsa ho senya botsitso, ho taboha le matla a ho tsitsa, hammoho le tlhokahalo ea ho fokotsa ho satalla le porosity e phahameng haholo, pampiri ea kraft ea boleng bo phahameng ka ho fetisisa e na le litlhoko tse phahameng bakeng sa 'mala, sebopeho, botsitso le boleng bo botle.
Ho fihlella maemo a mmala le boleng bo botle, makhasi a tlameha ho fifala ho fihlela khanya e pakeng tsa 24% le 34% ha a ntse a boloka boleng ba 'mala o mosehla le bofubedu bo sa fetohe, ke hore, ho boloka matla a makhasi a masoeu.
Mokhoa oa ho etsa pampiri ea Kraft
Ts'ebetso ea ho etsa pampiri ea kraft e kenyelletsa mekhahlelo e latelang.
1. Sebopeho sa lisebelisoa tse tala
Mofuta ofe kapa ofe oa mokhoa oa ho etsa pampiri o tšoana, o fapane feela ka boleng, botenya, le ho eketsoa ha litšobotsi tse eketsehileng. Pampiri ea kraft e entsoe ka makhasi a mapolanka a nako e telele, 'me e na le litekanyetso tse phahameng tsa thepa ea' mele. Ts'ebetso ena e fana ka motsoako oa makhasi a softwood le hardwood a fihlelang litekanyetso tsa boleng ba pampiri ea kraft ea pele. Mahlaku a mapolanka a Broadleaf a etsa hoo e ka bang 30% ea kakaretso ea tlhahiso. Karolelano ena ea thepa e tala ha e na phello ho matla a 'mele a pampiri, empa e na le tšusumetso e kholo ho gloss le litekanyetso tse ling.
2. Ho pheha le ho soeufatsa
Kraft pulp e tlameha ho ba le likhoele tse fokolang tsa likhoele tse mahoashe le 'mala o tsitsitseng, hammoho le ho fihlela litlhoko tsa mekhoa ea ho pheha ea boleng bo holimo le ea bleaching. Ho lumeloa ka bophara hore ho pheha le ho soeufatsa ho fapana haholo lipakeng tsa lisampole tsa lehong. Haeba mola oa pulp o ka arola softwood le hardwood pulping, softwood le hardwood pheha le bleaching li ka khethoa. Mokhahlelo ona o sebelisa ho pheha coniferous le lehong le thata, hammoho le bleaching e kopantsoeng ka mor'a ho pheha. Ts'ebetsong ea tlhahiso, mefokolo ea boleng joalo ka likhoele tsa fiber tse sa tsitsang, likhoele tse mahoashe tsa likhoele, le 'mala o sa tsitsang oa pulp li tloaelehile.
3.Ho hatella
Ho ntlafatsa ts'ebetso ea pulping ke mohato oa bohlokoa oa ho eketsa boima ba pampiri ea kraft. Ka kakaretso, ho eketsa khatello ea makhasi le ho boloka porosity ea eona e ntle le ho satalla ho tlase hoa hlokahala ho ntlafatsa ho tiea ha pampiri, ho teteana le ho ts'oana.
Pampiri ea Kraft e na le matla a maholo le liphoso tse ka lekanyetsoang ka ho kheloha ho ea holimo le ka mahlakoreng. Ka lebaka leo, litekanyo tse nepahetseng tsa pulp ho bophara ba pampiri, li-screen shaker, le liforomo tsa marang-rang li sebelisoa ho ntlafatsa limaraka. Mokhoa oa ho hatisa o sebelisoang ho etsa pampiri o ama ho kenella ha moea oa eona, ho satalla le ho boreleli. Ho hatella ho fokotsa porosity ea lakane, ho theola ho kenella ha eona le vacuum ha ho ntse ho eketsa tiiso; e ka boela ea eketsa matla a 'mele a pampiri.
Tsena ke litsela tseo hangata kraft pampiri e etsoang ka tsona.
