Ukwakhiwa kwamaphepha we-bamboo eChina kunomlando omude. U-Bamboo Fibrphology kanye nokwakheka kwamakhemikhali kunezimpawu ezikhethekile. Ubude obumaphakathi wefiber bude, kanye ne-micross celldown udonga lukhethekile, ukushaya ngamandla kokusebenza kokuthuthukiswa kwe-pulp kuhle, kunikeza i-pulp epinki ye-Pillical Properties: i-opacity ephezulu kanye nokukhanyisa kokusakazeka coefflent. Ukuqukethwe kwe-Bamboo Raw eluhlaza (cishe ama-23% kuya ku-32%) kuphakeme, kunqunywa ukupheka kwayo i-pulp nge-alkali ephezulu ne-sulfide (sulfide ngokuvamile ama-20% kuya ku-25%), eduze kwezinkuni ezi-25%), eduze kwezinkuni ezivuthayo; Izinto ezisetshenziswayo, okuqukethwe kwe-hemishellulose kanye ne-silicon kuphakeme, kepha futhi nasekuhlanzeni upulethi, ukuhwamuka komkhathi omnyama wokuhwamuka kanye nemishini yokuhlushwa okujwayelekile kuletha ubunzima. Noma kunjalo, izinto eziluhlaza be-bamboo aziyona into enhle eluhlaza ekwenziweni kwamaphepha.
I-future bamboo medium kanye nesilinganiso samakhemikhali e-pulp mighter bleaching system, izosebenzisa inqubo ye-TCF noma ye-ECF. Ngokuvamile, kuhlanganiswe nokujula kokuncishiswa komoya kanye nokuhlelwa komoya-mpilo kokuphamba, ukusetshenziswa kwe-TCF noma ubuchwepheshe be-TCF noma ubuchwepheshe be-TCF noma i-ECF, i-Pulp ye-BEACHP ehlukile, i-bamboo pulp ingahlanganiswa i-88% ~ 90% iso elimhlophe.
Ukuqhathaniswa kwe-bamboo ECF ne-TCF Bleaching
Ngenxa yokuqukethwe okuphezulu kwe-bamboo ephezulu, kudinga ukuhlanganiswa nobuchwepheshe bokuhlelwa okujulile no-oxygen ukucacisa ubuchwepheshe ukulawula inani le-kappa le-ECPRry Expring Expring ECF ne-TCF (Kunconyiwe <10), i-acid Ukuhlekisa noma nge-eop-stage tcf bleaching ukulandelana, konke okungahle kwenziwe i-bamboo pulp evile
Ukusebenza kwe-Bleaching kwezinto zokwakha ezihlukene ze-bamboo kuyahlukahluka kakhulu, i-kappa kuya ku-11 ~ 16 noma ngaphezulu, ngisho ne-ECF eneziteji ezimbili ne-TCF, ipulpiti kuphela, i-pulp ingafinyelela kuphela amazinga angu-89%.
Uma kuqhathaniswa ne-TCF Bamboo Pulp, i-ECF Bleached Bamboo Pulp inokulahleka okuncane okuthe xaxa nokubonakala okuphezulu, okuvame ukufinyelela ngaphezu kwe-800ml / g. Kepha ngisho ne-bamboo ye-bambobo ethuthukisiwe yesimanje ethuthukisiwe, i-viscosity ingafinyelela kuphela ngo-700ml / g. Ikhwalithi ye-pulp ye-ECF ne-TCF ye-pulp iyiqiniso elingenakuphikwa, kepha ukucatshangelwa okuphelele kwekhwalithi ye-pulp, izindleko zokutshala imali, i-bamboo pulp bleaching usebenzisa i-ECF Bleaching noma i-TCF Bleaching, ayikapheli. Abenzi bezinqumo ezihlukile basebenzisa izinqubo ezahlukahlukene. Kepha kusukela kumkhuba wokuthuthuka okuzayo, i-bamboo pulp ECF kanye ne-TCF Bleaching izoba khona isikhathi eside.
Abasekeli be-ECF Bleaching Technology bakholelwa ukuthi i-ECF Bleached Pulp inekhwalithi engcono ye-pulp, ngokusetshenziswa kwamakhemikhali ambalwa, ukusebenza okuphezulu okuphezulu, ngenkathi uhlelo lwemishini luvuthiwe futhi lusebenza ukusebenza. Kodwa-ke, abameli bobuchwepheshe be-TCF Bleaching Technology bathi ubuchwepheshe be-TCF Bleaching bunezinzuzo zamanyala angaphansi akhuphukayo esitshalweni sokuxubha, izidingo eziphansi zokulwa nokuwohloka kwemishini, kanye nokutshala imali okuphansi. I-Sulphelate bamboo pulp tcf chlorine-free bleaching umugqa wokukhiqiza amukeliswa uhlelo lokufafaza oluvaliwe, ukufakwa kwamanzi okufaka izitshalo kungalawulwa ngo-5 kuye ku-10m3 / T Pulp. I-Wastewater kusuka esigabeni (PO) ithunyelwa esigabeni sokudilizwa komoya-mpilo ukuze isetshenziswe, futhi i-wastewater kusuka esigabeni ihlinzekwa engxenyeni yokuwasha ye-sweunce ukuze isetshenziswe, bese ekugcineni ingena emanzini abuyiselwe e-Alkali. Ngenxa yokuxubha ngaphandle kwe-chlorine, amakhemikhali awawonakalo, imishini yokufaka insimbi ayidingi ukusebenzisa i-titanium nensimbi ekhethekile, insimbi evamile engagqwali, ingabe izindleko zokutshala imali zingaphansi. Uma kuqhathaniswa nomugqa wokukhiqiza we-TCF Pulp, izindleko zokutshalwa kwezimali ze-ECF Pulp Production Line ukuze zibe ngama-20% ziye phezulu ezingama-25%, ngokutshala imali yokukhiqiza i-pulp kungamaphesenti ayi-10 kuye kwayi-15%, futhi Ukusebenza kuyinkimbinkimbi ngokwengeziwe.
Ngamafuphi, i-bamboo pulp tcf kanye nokukhiqizwa okumhlophe okumhlophe okuphezulu kwe-88% kuya ku-90% Bleached bamboo pulp kungenzeka. Ukuphambuka kufanele kusetshenziswe ebukhwini bokuhlelwa ngokujulile, ukudilizwa komoya-mpilo ngaphambi kokufaka i-bleaching, ukulawula ipulpiti kwisistimu ye-bleaching kappa, ukugcwala kusetshenziswa ukulandelana kokufiphaza okune-bleachi. Ukulandelanisa okuphakanyisiwe kwe-ECF kwe-ECF ye-Bamboo Pulp yi-OD (EOP) D (PO), od (eop) dp; Ukulandelanisa kwe-L-ECF Bleaching yi-OD (EOP) Q (PO); Ukulandelana kwe-TCF Bleaching yi-EOP (ZQ) (PO) (PO), O (zq) (PO) (ZQ) (PO). Njengokwakheka kwamakhemikhali (ikakhulukazi okuqukethwe kwe-lignin) kanye ne-fiber morphology kwehlukahluka kakhulu phakathi kwezinhlobo ezahlukene ze-bamboo, kufanele kwenziwe isifundo esihlelekile ekusebenzeni kwama-bamboo ahlukene ngaphambi kokwakhiwa kwalesi sitshalo ukunikeza umhlahlandlela wokuthuthuka kwentuthuko imizila yenqubo nemibandela.
