● Ho etsa pampiri ea bamboo pulp
Ho tloha ha nts'etsopele e atlehileng ea indasteri le ts'ebeliso ea bamboo, lits'ebetso tse ngata tse ncha, mahlale le lihlahisoa tsa ts'ebetso ea bamboo li hlahile ka mor'a e 'ngoe, e leng se ntlafalitseng haholo boleng ba tšebeliso ea bamboo. Ntshetsopele ya theknoloji ya China ya ho phuphura ka metjhini e sentse ka mokgwa wa setso wa ho sebetsa ka matsoho mme e fetohela ho mmotlolo wa tlhahiso ya diindaseteri le tsa indasteri. Mekhoa ea hajoale ea tlhahiso ea makhasi a bamboo ke mochini, oa lik'hemik'hale le oa lik'hemik'hale. Lehlaka la bamboo la China hangata le na le lik'hemik'hale, tse etsang karolo ea 70%; lik'hemik'hale tsa lik'hemik'hale li ka tlaase ho 30%; tšebeliso ea mekhoa ea mechine ho hlahisa makhasi a bamboo e lekanyelitsoe sethaleng sa liteko, 'me ha ho na tlaleho e kholo ea indasteri.
1.Mechanical pulping mokhoa
Mokhoa oa mochini oa pulping ke oa ho sila bamboo hore e be likhoele ka mekhoa ea mochini ntle le ho eketsa lisebelisoa tsa lik'hemik'hale. E na le melemo ea tšilafalo e tlase, sekhahla se phahameng sa pulping le ts'ebetso e bonolo. Tlas'a boemo ba taolo e matla e ntseng e eketseha ea tšilafalo le khaello ea lisebelisoa tsa mapolanka ka har'a naha, makhasi a bamboo a entsoeng ka mochini a 'nile a nkoa e le a bohlokoa ke batho.
Le hoja pulping ea mechine e na le melemo ea tekanyo e phahameng ea pulping le tšilafalo e tlaase, e sebelisoa haholo indastering ea pulping le ea ho etsa pampiri ea thepa ea coniferous e kang spruce. Leha ho le joalo, ka lebaka la litaba tse phahameng tsa lignin, molora, le 1% NAOH e nkiloeng ka har'a lik'hemik'hale tsa bamboo, boleng ba makhasi bo futsanehile 'me ho thata ho finyella litlhoko tsa boleng ba pampiri ea khoebo. Tšebeliso ea indasteri ha e tloaelehe 'me hangata e boemong ba lipatlisiso tsa saense le lipatlisiso tsa tekheniki.
2.Mokhoa oa pulping oa lik'hemik'hale
Mokhoa oa ho hula ka lik'hemik'hale o sebelisa bamboo joalo ka thepa e tala 'me o sebelisa mokhoa oa sulfate kapa mokhoa oa sulfite ho etsa makhasi a bamboo. Lisebelisoa tse tala tsa bamboo lia hlahlojoa, li hlatsuoa, li felloa ke metsi, li phehiloe, lia hloekisoa, lia hloekisoa, li hlatsuoa ka li-countercurrent, tlhahlobo e koetsoeng, delignification ea oksijene, bleaching le lits'ebetso tse ling ho etsa makhasi a bamboo. Mokhoa oa ho phunya lik'hemik'hale o ka sireletsa fiber le ho ntlafatsa sekhahla sa pulping. Motsoako o fumanoeng ke oa boleng bo botle, o hloekile ebile o bonolo, o soeufalitsoe habonolo, 'me o ka sebelisoa ho hlahisa pampiri ea ho ngola ea boemo bo holimo le pampiri ea khatiso.
Ka lebaka la ho tlosoa ha palo e kholo ea lignin, molora le li-extracts tse fapa-fapaneng ts'ebetsong ea ho hula ka mokhoa oa lik'hemik'hale, sekhahla sa pulping sa bamboo pulping se tlaase, ka kakaretso 45% ~ 55%.
3.Chemical Mechanical Pulping
Chemical Mechanical Pulping ke mokhoa o sebelisang bamboo joalo ka thepa e tala, 'me o kopanya litšobotsi tse ling tsa lik'hemik'hale le pulping ea mochini. Chemical Mechanical Pulping e kenyelletsa mokhoa oa halofo ea lik'hemik'hale, mokhoa oa mochini oa lik'hemik'hale le mokhoa oa lik'hemik'hale oa thermomechanical.
Bakeng sa pulping ea bamboo le ho etsa pampiri, sekhahla sa ho phunya ha lik'hemik'hale tsa lik'hemik'hale se phahame ho feta sa lik'hemik'hale tsa lik'hemik'hale, tseo ka kakaretso li ka fihlang 72% ~ 75%; boleng ba makhasi a fumanoang ke lik'hemik'hale tsa lik'hemik'hale tsa lik'hemik'hale li phahame haholo ho feta tsa pulping ea mechine, e ka finyellang litlhoko tse akaretsang tsa tlhahiso ea pampiri ea thepa. Ka nako e ts'oanang, litšenyehelo tsa ho hlaphoheloa ha alkali le phekolo ea likhoerekhoere li boetse li pakeng tsa lik'hemik'hale tsa lik'hemik'hale le pulping ea mechine.

Kaha bamboo o na le sebopeho se sekoti, thepa ea ho seha e fapane le ea lehong. Lisebelisoa tse sebelisoang ka tloaelo tsa bamboo slicing (flaking) haholo-holo li kenyelletsa mochini o sehang oa bamboo, mochini o sehang oa bamboo le drum chipper. Li-roller bamboo cutters le disc bamboo cutters li sebetsa hantle haholo, empa boleng ba lichipisi tsa bamboo tse sebetsitsoeng (sebopeho sa lehlaka la bamboo) ha bo ntle joalo ka ba meropa. Basebelisi ba ka khetha lisebelisoa tse nepahetseng tsa ho seha (flaking) ho latela sepheo sa pulp ea bamboo le litšenyehelo tsa tlhahiso. Bakeng sa limela tse nyenyane le tse mahareng tsa bamboo pulp (se hlahisoang <100,000 t/a), lisebelisoa tsa lapeng tsa bamboo slicing li lekane ho fihlela litlhoko tsa tlhahiso; bakeng sa limela tse kholo tsa bamboo pulp (output ≥100,000 t/a), lisebelisoa tse tsoetseng pele tsa machaba tsa ho khaola (flaking) li ka khethoa.
Lisebelisoa tsa ho hlatsoa li-bamboo chip li sebelisoa ho tlosa litšila, 'me ho tlalehiloe lihlahisoa tse ngata tse nang le tokelo ea molao China. Ka kakaretso, ho sebelisoa li-vacuum pulp washers, li-washer tsa khatello ea khatello le li-washer tsa pulp ea lebanta li sebelisoa. Likhoebo tse mahareng le tse kholo li ka sebelisa li-washer tse ncha tsa "double roller displacement" tsa "pulp washer" kapa li-washer tse matla tse hlakisang metsi.
Lisebelisoa tsa ho pheha tsa bamboo chip li sebelisetsoa ho nolofatsa lehlaka la bamboo le karohano ea lik'hemik'hale. Likhoebo tse nyane le tse mahareng li sebelisa lipitsa tsa ho pheha tse otlolohileng kapa li-continuous cookers tse tšekaletseng. Likhoebo tse kholo li ka sebelisa li-cookers tse tsoelang pele tsa Camille tse hlatsoang metsi ho ntlafatsa ts'ebetso ea tlhahiso, 'me lihlahisoa tsa pulp le tsona li tla eketseha ho latela, empa li tla eketsa litšenyehelo tsa nako e le' ngoe.
