● Inqubo yokwenza papermaking ye-bamboo pulp
Kusukela ekuthuthukisweni okuphumelelayo kwezimboni kanye nokusetshenziswa kwe-bamboo, izinqubo eziningi ezintsha, ubuchwepheshe kanye nemikhiqizo yokuhlelwa kwe-bamboo kuqhamuke ngokulandelana, okuye kwathuthukisa kakhulu inani lokusetshenziswa kwe-bamboo. Ukuthuthukiswa kobuchwepheshe be-chin we-chinnited yeChina kuphule indlela yendabuko yendabuko futhi kuguqula imodeli yokukhiqiza ethuthukile nezezimboni. Izinqubo zokukhiqiza ezithandwayo zamanje ze-bamboo pulp ziyimishini yemishini, yamakhemikhali kanye namakhemikhali. I-bamboo pulp yaseChina ingamakhemikhali kakhulu, aphendule cishe ama-70%; I-Mechanical Mechanical incane, ngaphansi kwama-30%; Ukusetshenziswa kwezindlela zemishini ukukhiqiza i-bamboo pulp kukhawulelwe esigabeni sokuhlola, futhi akukho mbiko omkhulu wezimboni.
1.Mechanical Phringping indlela
Indlela yokuphambuka emishini yokugaya i-bamboo ibe yimicu ngezindlela zemishini ngaphandle kokungeza ama-ejenti wamakhemikhali. Inezinzuzo zokungcoliswa okuphansi, izinga eliphakeme lokuphamba kanye nenqubo elula. Ngaphansi kwesimo sokulawulwa kokungcoliswa okuthe xaxa nokushoda kwezinsizakusebenza ze-Wood Pulp ezweni, i-Mechanical Bamboo Pulp ibekelwe abantu kancane kancane.
Yize i-mehendi Pringping inezinzuzo zezinga eliphakeme lokuphamba kanye nokungcoliswa okuphansi, kusetshenziswa kabanzi embonini ephuculo nasezimboni ezingenasisekelo zezinto ezinama-coniferous ezifana ne-spruce. Kodwa-ke, ngenxa yokuqukethwe okuphezulu kwe-lignin, umlotha, kanye ne-1% naoh kukhishwe ekubumbeni amakhemikhali ku-bamboo, ikhwalithi ye-pulp ayimpofu futhi kunzima ukufeza izidingo zekhwalithi yephepha lokuhweba. Isicelo sezimboni asivamile futhi ikakhulukazi esiteji sokucwaninga kwesayensi kanye nokuhlola ubuchwepheshe.
Indlela yokuphambuka ye-2.Chemical
Indlela yokuphambuka yamakhemikhali isebenzisa i-bamboo njengento eluhlaza futhi isebenzisa indlela ye-sulfate noma indlela ye-sulfite yokwenza i-bamboo pulp. Izinto zokulala ze-bamboo zivinjelwe, zigezwe, ziphethwe ngamanzi, ziphekwe, zihlanjululwe, zihlanjululwe, zivikelekile, ukuhlolwa komoya, ukufakwa komoya-mpilo, ezinye izinqubo ukwenza i-bamboo pulp. Indlela yokuphambuka yamakhemikhali ingavikela i-fiber futhi ithuthukise izinga lokuphamba. I-pulp etholwe ikhwalithi enhle, ihlanzekile futhi ithambile, kulula ukuyiphinda, futhi ingasetshenziselwa ukukhiqiza iphepha lokubhala lebanga eliphakeme nephepha lokuphrinta.
Ngenxa yokususwa kwenani elikhulu le-lignin, umlotha kanye nokukhishwa okuhlukahlukene kwinqubo yokuphamba kwendlela yokuphambuka kwamakhemikhali, izinga lokuphamba le-bamboo purping liphansi, ngokuvamile ama-45% ~ 55% ~ 55%.
I-3.Chemical Mechanical Phringping
I-Mechamical Mechanical Phring iyindlela yokuphamba esebenzisa i-bamboo njengento eluhlaza futhi ihlanganisa ezinye izici zokuphahlazeka kwamakhemikhali kanye nokuphaphana kwemishini. Ukuphambuka kwemishini yamakhemikhali kufaka indlela yesikhathi samakhemikhali, indlela yamakhemikhali kanye nendlela yamakhemikhali ye-thermomechanical.
For bamboo purping kanye nokwehla, izinga lokuphamba kophahla lwemishini yamakhemikhali liphakeme kunalolo lokuphahlazeka kwamakhemikhali, okuvame ukufinyelela ama-72% ~ 75%; Izinga le-pulp elitholwe yimishini yamakhemikhali yokuphambuka liphakeme kakhulu kunaleso sokwehla kwemishini, esingahlangabezana nezidingo ezijwayelekile zokukhiqizwa kwamaphepha okuhweba. Ngasikhathi sinye, izindleko zokuvuselelwa kwe-alkali yokutakula nokuthuthwa kwendle nazo ziphakathi kokuphahlazeka kwamakhemikhali kanye nokugibela imishini.
▲ bamboo purping umugqa wokukhiqiza
● Ama-Bamboo Pulp Pulp PAPPERMANKZI
Imishini yengxenye eyakhekayo yomugqa wokukhiqiza we-bamboo pulp papermaking iyafana naleyo yomugqa wokukhiqiza uPulp. Umehluko omkhulu kakhulu we-bamboo pulp papermaking imishini etholakala ezigabeni zokulungiselela ezinjengokukhanya, ukugeza nokupheka.
Ngoba i-bamboo inesakhiwo esingenalutho, imishini yokukhanya yehlukile ihlukile kweyokhuni. Imishini esetshenziswayo esetshenziswa ngokujwayelekile (i-flaking) imishini esetshenziswa kakhulu Ama-roller bamboo cutters kanye nabasiki be-disc bamboo banokusebenza okuphezulu okusebenzayo, kepha ikhwalithi yama-bamboo chips acutshunguliwe (ukwakheka kwe-chip bomboo) akukuhle njengokuthi i-drum chippers. Abasebenzisi bangakhetha imishini efanelekile ye-slicing (flaking) efanele ngokwenhloso ye-bamboo pulp kanye nezindleko zokukhiqiza. Okwezitshalo ezincane ze-bamboo pulp ezincane naphakathi nendawo (okuphumayo Izitshalo ezinkulu ze-bamboo pulp (okuphuma ≥100,000 t / a), imishini ethuthukisiwe yasemazweni athuthukile (i-flaking) engakhethwa.
Imishini yokuwasha ye-bamboo chip isetshenziselwa ukususa ukungcola, futhi imikhiqizo eminingi enelungelo lobunikazi iye yabikwa eChina. Ngokuvamile, ama-basher we-vacuum pulp, asetshenziswa ama-washer we-pulp kanye nama-bult pulp washer. Amabhizinisi aphakathi nendawo futhi amakhulu angasebenzisa umshini wokuhlanza ama-pulp washer omusha we-pulp noma ama-washer aqinile asondelana ajwayelekile.
Imishini yokupheka ye-bamboo chip chip isetshenziselwa ukwathambisa kwe-bamboo chip Amabhizinisi amancane naphakathi aphakathi nendawo asebenzisa amabhodwe okupheka aqonde mpo noma abapheki abavundlile abaphekayo. Amabhizinisi amakhulu angasebenzisa abapheki abaqhubekayo be-Camille ngokugeza ngokungenisa ukuthuthukisa ukusebenza kahle kokukhiqiza, kanye nesivuno se-pulp sizokhuphuka ngokufanele, kepha sizokhulisa izindleko zokutshala imali ngesikhathi esisodwa.
I-1.bamboo pulp papermaking inamandla amakhulu
Ngokusekelwe ekuhlolweni kwezinsizakusebenza ze-bamboo yaseChina kanye nokuhlaziywa kokufaneleka kwe-bamboo uqobo ekwakheni kabusha imboni ye-bamboo Puring ayikwazi kuphela ukudambisa inkinga yezinto zokwakha amaphepha eziqinile embonini yamaphepha aseChina, kodwa futhi kube yindlela ephumelelayo yokushintsha Ukwakheka kwezinto ezibonakalayo ezibonakalayo zemboni yamaphepha ephakethe futhi kunciphise ukuncika kuma-hix angenisiwe izinkuni. Ezinye izazi zihlaziye ukuthi izindleko zeyunithi ye-bamboo pulp ngeyunithi ngalinye lingama-30% aphansi kunalesophawu, i-struce, ikhwalithi ye-bamboo pulp ilingana neyomapulangwe.
Ukuhlanganiswa kwephepha okungu-2.Inforkos kuyindlela ebalulekile yentuthuko
Ngenxa yezinzuzo ezikhula ngokushesha futhi ezivuselelekayo ze-bamboo, eziqinisa ukutshala kwamahlathi akhethekile akhula ngokuqinile kanye nokusungula isisekelo sokukhiqiza se-bamboo pulp esihlanganisa ihlathi nephepha kuzoba yisiqondisi sokuthuthuka okuqhubekayo kwemboni ye-pulp yaseChina ne-Pulping, ukunciphisa Ukuthembela kuma-Chips ezinkuni angenisiwe kanye ne-pulp, futhi kwakha izimboni zikazwelonke.
I-3.Cluster bamboo Phring Phring inekhono elikhulu lokuthuthuka
Embonini ye-bamboo esebenza njengamanje, ngaphezu kwama-90% wezinto ezingavuthiwe ezenziwe nge-mosboo bomboo (Phoebe Nanmu), esetshenziselwa ikakhulukazi ukukhiqiza izinto zasendlini kanye nezinto zokwakha ezakhiwo. I-Bamboo Pulp Papermaking futhi isebenzisa kakhulu uMoso Bamboo (Phoebe Nanmu) kanye no-Cycad bamboo njengezinto zokwakha eziluhlaza, ezakha isimo sokuncintisana esibonakalayo, esakha isimo sokuncintisana esingavuthiwe futhi asilungele ukuthuthukiswa okuqhubekayo komkhakha. Ngokwesisekelo sezinhlobo ezikhona ze-bamboo ezikhona, imboni ye-bamboo pulp papermaking kufanele ithuthukise izinhlobo ezahlukahlukene ze-bamboo zokusetshenziswa kwezinto ezibonakalayo, zisebenzise ngokugcwele i-cycad bamboo ethosiwe ye-cycad beamboo, i-cast dragon bamboo, i-dendroculalus latiflorus futhi Olunye uBarboo ongenacala lokuphamba kanye nokuphambana, futhi uthuthukise ukuncintisana kwemakethe.
I-bamboo ehlanganisiwe ingasetshenziswa njengento ebalulekile ye-pulp
