Izinto ze-Bamboo zinokuqukethwe okuphezulu kwe-cellulose, i-Slender fiber rap, izakhiwo ezinhle zemishini kanye ne-plastiki. Njengenye yezinto ezinhle zokwakha izinkuni ezihlaselayo zokhuni, i-bamboo ingahlangabezana nezidingo ze-pulp zokwenza iphepha eliphakathi nelokuphela. Ucwaningo lukhombisile ukuthi ukwakheka kwamakhemikhali we-bamboo kanye ne-fiber proceties zinezici ezinhle zokuphamba. Ukusebenza kwe-bamboo pulp kungokwesibili kuphela ku-coniferous izinkuni uginindela, futhi kungcono kune-pulp yezinkuni ebanzi kanye ne-pulp yotshani. IMyanmar, i-India namanye amazwe baphambili emhlabeni emkhakheni we-bamboo Phringping kanye nokwakheka. Imikhiqizo ye-bamboo yaseChina yaseChina kanye nemikhiqizo yamaphepha ingeniswa ngokuningiliselwa kusuka eMyanmar naseNdiya. Ukuthuthukisa ngamandla i-bamboo puryping kanye nomkhakha wamapakethe kubaluleke kakhulu ekunciphiseni ukushoda kwamanje kwezinto zokwakha izinkuni.
U-Bamboo ukhula ngokushesha futhi ngokuvamile angavunwa ngeminyaka emithathu kuya kwengu-4. Ngaphezu kwalokho, amahlathi e-bamboo anomphumela oqinile wekhabhoni, enza izinzuzo zezomnotho, zemvelo nezenhlalo zemboni ye-bamboo zigqamile. Njengamanje, ubuchwepheshe bokukhiqiza be-bamboo bulpoo pulp kanye nemishini ikhule kancane kancane, futhi imishini esemqoka efana nokushefa nokuphamba kukhiqizwe ekhaya. Imigqa yokukhiqiza eyahlukene futhi ephakathi nendawo ye-bamboo ithuthukisiwe futhi yafakwa eGuizhou, eSichuan nakwezinye izindawo.
Izakhiwo zamakhemikhali ze-bamboo
Njenge-biomass material, bamboo inezinhlaka ezintathu ezinkulu zamakhemikhali: i-cellulose, i-hemicelulose, kanye ne-lignin, ngaphezu kwenani elincane le-pectin, isitashi, ama-polysaccharides, ne-wax. Ngokuhlaziya ukwakheka kwamakhemikhali kanye nezimpawu ze-bamboo, singakwazi ukuqonda ubuhle kanye nokubi kwe-bamboo njenge-pulpo kanye nephepha.
1. UBAmboo unokuqukethwe okuphezulu kwe-cellulose
Iphepha eliphakeme eliqediwe linezidingo eziphakeme zezinto zokwenziwa kwezindwangu ze-pulp, ezidinga ukukhuphuka okuqukethwe kwe-cellulose, okungcono, kanye nekwehlisa okuqukethwe kweLignin, ama-polysaccharides nokunye okukhishwe, okungcono. U-Yang Rendang et al. qhathanisa izingxenye eziphambili zamakhemikhali zezinto ze-biomass ezifana ne-bamboo (Phyllostachys kanye nokotshani kakolweni (35.23%); Okuqukethwe kwe-hemicellulose (Pentosan) kwakuyi-poplar (22.61%), i-bamboo (21.12%), utshani kakolweni (19.30%), kanye ne-masson pine (8.24%); Okuqukethwe kwe-lignin kwakunguBamboo (30.67%), i-masson pine (27.97%), i-poplar (17.10%), nokotshani kakolweni (11.93%). Kungabonakala lokho phakathi kwezinto zokuqhathanisa ezine, i-bamboo ingukuphahlazeka okubonakalayo kwesibili kuphela ku-masson pine.
2. Imicu ye-bamboo iba isikhathi eside futhi inesilinganiso esikhulu se-Aspect
Ubude obuphakathi be-bamboo fibers yi-1.49 ~ 2.28 mm, ububanzi obuphakathi bungu-12.24 ~ 17.32 μm, kanye nesilinganiso se-aspect singu-122 ~ 165; Ubukhulu obuphakathi kodonga lwefayibha lungu-3.90 μm, kanye nesilinganiso sodonga-to-cavity ngu-4.20 ~ 7.50, okuyi-fiber odongeni elibanzi ngesilinganiso esikhulu se-aspio. Izinto ze-Pulp zithembele ikakhulu kwiselula kusuka ezintweni ze-biomass. Izinto ezinhle ze-biofiber ezivuthayo ze-papermang zidinga okuqukethwe okuphezulu kwe-cellulose kanye nokuqukethwe okuphansi kwe-lignin, okungakwazi ukukhulisa isivuno se-pulp kuphela, kepha futhi kunciphise umlotha nokukhishwa. U-Bamboo unezici zemicu emide kanye nesilinganiso esikhulu sezici, okwenza i-fiber izohlangana kaninginingi endaweni ngayinye yeyunithi ngemuva kokuthi ipulpo ye-bamboo yenziwa ephepheni, futhi amandla ephepha angcono. Ngakho-ke, ukusebenza kwe-PricePop ye-bamboo kusondelene naleyo ngokhuni, futhi kunamandla kunezinye izitshalo zotshani ezifana notshani, utshani kakolweni kanye neBagasse.
3. I-Bamboo Fibre inamandla amakhulu we-fiber
I-Bamboo Clullulose ayivuselelwa kuphela, inenkohliso, ihambisane ne-biocoma, i-hydrophilic, futhi inezakhiwo ezinhle kakhulu zemishini nokushisa, kepha futhi inezakhiwo ezinhle zemishini. Ezinye izazi zaqhuba izivivinyo ezishubile ngezinhlobo eziyi-12 zemicu ye-bamboo futhi zathola ukuthi amamodulomu awo anstic namandla ashubile adlula lezo zezinkuni zokukhula kwehlathi elikhulisa amahlathi akhula ngokushesha okusheshayo. Wang et al. Qhathanisa izakhiwo zemishini ezi-Tensile zezinhlobo ezine zemicupho: bamboo, uKenaf, fir, noRamie. Imiphumela ikhombisile ukuthi i-modulus namandla we-bamboo fiber ayephakeme kunaleyo yezinye izinto ezintathu zefayibha.
4. UBAmboo unomlotha ophakeme nokukhipha okuqukethwe
Uma kuqhathaniswa nokhuni, i-bamboo inokuqukethwe okuphezulu komlotha (cishe ama-1.0%) kanye ne-1% naoh okukhishwe (cishe ama-30.0%), azokhiqiza ukungcola okwengeziwe ngesikhathi sokukhishwa, okungafanele ukwelashwa kwamanzi okuphuma kanye Umkhakha wamaphepha, futhi uzokwandisa izindleko zokutshala imali kwemishini ethile.
Njengamanje, ikhwalithi ye-Bamboo Pulp Pulp Pulp Pulp Pulloo Pulp Pulp Pulp Pulp Pull ye-Yashi ifinyelele ezimfuneko ezijwayelekile ze-EU Rohs, idlulise i-EU AP (2002) -1, i-US FDA kanye nezinye izivivinyo ze-FSc 100% yehlathi, futhi futhi yinkampani yokuqala eSichuan ukuthola ukuphepha kweChina kanye nesitifiketi esinempilo; Ngasikhathi sinye, ihlelwe ngokuthi "Umkhiqizo we-Sight Sugameriof Sampling ofanelekile" ngumkhiqizo ofanelekayo wePhepha Lemikhiqizo Yemikhiqizo yePhepha iminyaka eyishumi elandelanayo, futhi uzuze ama-honors anjenge- "National Izinga elifanelekile" kusuka kwikhwalithi ye-China Ukuvakasha.
