Muna Zvita 2021, State Forestry and Grassland Administration, National Development and Reform Commission nemamwe madhipatimendi gumi vakabatana vakapa "Maonero eKumhanyisa Iyo Innovation uye Kubudirira kweBamboo Indasitiri". Nzvimbo dzakasiyana-siyana dzakatevedzana dzakagadzira mitemo yekutsigira kupa rutsigiro rwakasimba rwemitemo yekusimudzira budiriro yemhando yepamusoro yeindasitiri ye bamboo, kusanganisira iyo bamboo pulp neindasitiri yemapepa. nyika yangu huru ye bamboo pulp uye nzvimbo dzekugadzira mapepa dzakanangidzirwa muSichuan, Guizhou, Chongqing, Guangxi, Fujian neYunnan. Pakati pavo, Sichuan parizvino ndiyo yakakura bamboo pulp uye purovhinzi yekugadzira mapepa munyika yangu. Mumakore achangopfuura, Dunhu reSichuan rakagadzira zvine simba mubatanidzwa wemapulp uye mapepa indasitiri sumbu re "bamboo-pulp-pepa-processing-sales", yakagadzira inotungamira mhando ye bamboo pulp pamba bepa, uye yakashandura mabhenefiti egirinhi zviwanikwa zve bamboo kuita mabhenefiti ekuvandudza maindasitiri, kuwana mhedzisiro inoshamisa. Zvichienderana nehupfumi hwemushenjere zviwanikwa, Sichuan akarima emhando yepamusoro masango emasango, akavandudza hunhu hwemasango emushenjere, akadyara masango emushenjere pamateru anodarika madhigirii makumi maviri neshanu nenzvimbo yekurima ine materu e15 kusvika 25 madhigirii munzvimbo dzakakosha dzemvura dzinosangana negwara, nesainzi kusimudzira manejimendi emasango emushenjere, akasimudzira nesainzi manejimendi emasango emushenjere. uye ecological bamboo masango, uye akasimbisa akasiyana muripo uye rubatsiro rwemari. Mishenjere inochengeterwa yakawedzera zvishoma nezvishoma. Muna 2022, sango remushenjere mudunhu iri rakapfuura mamirioni gumi nemasere mu, richipa huwandu hukuru hwemhando yepamusoro bamboo fiber mbishi zvinhu zve bamboo pulping uye kugadzira mapepa, kunyanya bamboo pulp echisikigo ruvara rweimba mapepa. Kuti ive nechokwadi chemhando yebamboo pulp bepa reimba uye nekuvandudza ruzivo rwemavara emumba emba pamba nekune dzimwe nyika, iyo Sichuan Pepa Indasitiri Association yakanyorera kuTrademark Hofisi yeHurumende Intellectual Property Hofisi yekunyoreswa kwe "Bamboo Pulp Pepa" chiratidzo chemubatanidzwa. Kubva panguva yakapfuura yeruoko rumwe chete kurwira kusvika kune yazvino yepakati uye yakakura-kukura budiriro, kubata pamwe chete mukudziya uye kukunda-kuhwina kubatana kwave kwakanakira hunhu hwekusimukira kweSichuan Pepa. Muna 2021, pakanga paine mabhizinesi gumi nematatu ekupuruzira bamboo pamusoro pehukuru hwakatarwa mudunhu reSichuan, aine bamboo pulp yakabuda yematani 1.2731 miriyoni, gore negore kuwedzera kwe7.62%, inoverengera 67.13% yenyika yekutanga bamboo pulp kubuda, iyo inenge 80% yepepa; paive ne58 bamboo pulp emumba yemapepa base emabhizinesi emapepa aine gore negore kubuda kwematani miriyoni 1.256; paive ne248 bamboo pulp emumba ekugadzira mapepa emabhizinesi aine gore negore kubuda kwematani miriyoni 1.308. 40% yeyakasikwa bamboo pulp imba bepa inogadzirwa inotengeswa mudunhu, uye makumi matanhatu muzana inotengeswa kunze kwepurovhinzi uye kunze kwenyika kuburikidza ne e-commerce kutengesa mapuratifomu uye yenyika "Belt uye Road" chirongwa. Nyika inotarisa kuChina kune bamboo pulp, uye China inotarisa kuSichuan kuti iite pulp yemushenjere. Iyo Sichuan "bamboo pulp paper" brand yaenda pasi rose.
Michina mitsva
nyika yangu ndiyo inogadzira pasi rose ye bamboo pulp/bamboo dissolving pulp, ine mitsara gumi nemaviri yemazuva ano yekugadzira makemikari emushenjere ane simba rekugadzira repagore rinopfuura 100,000 matani, huwandu hwese hwekugadzira hunosvika 2.2 miriyoni matani, ayo 600,000 matani ari bamboo anonyungudutsa pulp. Fang Guigan, muongorori uye maneja wezvechiremba kuInstitute of Forest Products Chemical Industry yeChinese Academy of Forestry, agara akazvipira mukutsvagisa nekusimudzira matekinoroji akakosha nemidziyo yeindasitiri yenyika yangu ine goho repamusoro. Akataura kuti mushure mekuedza kwakabatana kweindasitiri, dzidzo uye tsvagiridzo, vaongorori vakapaza matekinoroji akakosha e bamboo pulp / kunyungudika kugadzirwa kwe pulp, uye yepamberi yekubikira uye bleaching matekinoroji nemidziyo zvakashandiswa zvakanyanya mukugadzira bamboo kemikari pulp. Kuburikidza neshanduko uye nekushandiswa kwesainzi uye tekinoroji yekutsvaga mhinduro senge "New Technologies yeAnoshanda Bamboo Pulping uye Papermaking" kubva "Gumi neMashanu-Makore Chirongwa", nyika yangu yakatanga kugadzirisa dambudziko reN uye P munyu chiyero mukuita kwekubvisa doro nhema silicon uye kurapa kwekubuda kunze. Panguva imwecheteyo, kufambira mberi kwebudiriro kwakaitwa mukuwedzera kwemuganho wekuchena kwe bamboo yakakwira-goho pulp bleaching. Pasi pemamiriro ehupfumi hwekuita bleaching agent dosage, kuchena kwe bamboo high-yego pulp kwawedzera kubva pasi pe65% kusvika pa70%. Parizvino, vaongorori vari kushanda kuti vapwanye mabhodhoro ehunyanzvi akadai sekushandiswa kwesimba rakawanda uye goho rakaderera mukugadzirwa kwe bamboo pulp, uye kuyedza kugadzira zvakanakira mukugadzirwa kwe pulp uye kuvandudza kukwikwidza kwemusika wepasi rose we bamboo pulp.
Mikana mitsva
Muna Ndira 2020, hurongwa hutsva hwepasi rose hwekurambidza mapurasitiki hwakaratidza huwandu hwezvirambidzo zvepurasitiki uye kusarudzwa kwedzimwe nzira, zvichiunza mikana mitsva kumakambani ekugadzira mapepa ne bamboo pulp. Nyanzvi dzakaratidza kuti pasi pe "dual kabhoni", bamboo, sechinhu chakakosha chisiri chehuni masango, inoita basa rakakosha pakuita kuti pasi rose kuchengetedzwa kwehuni, kuderera kwekabhoni girini kusimukira, uye kuvandudza raramo yevanhu. "Kutsiva purasitiki ne bamboo" uye "kutsiva huni ne bamboo" kune mukana mukuru uye hukuru hwekusimudzira maindasitiri. Bamboo inokura nekukurumidza, ine biomass yakakura uye yakapfuma muzviwanikwa. Hunhu hwe bamboo fiber morphology uye cellulose yemukati iri pakati pehuni coniferous uye yakafara-mashizha huni, uye iyo bamboo pulp inogadzirwa inofananidzwa nehuni pulp. Iyo bamboo pulp fiber yakarebesa kupfuura yehuni-yakafara, iyo sero madziro microstructure yakakosha, kurova kwesimba uye ductility zvakanaka, uye bleached pulp ine yakanaka optical properties. Panguva imwecheteyo, bamboo ine yakakwira cellulose yemukati uye yakanakisa fiber mbishi zvinhu zvekugadzira mapepa. Iwo akasiyaniswa maitiro e bamboo pulp uye huni pulp anogona kushandiswa kugadzira akasiyana epamusoro-ekupedzisira mapepa uye mapepa emapepa. Fang Guigan akataura kuti kusimukira kwakasimba kweiyo bamboo pulp uye indasitiri yemapepa haiparadzaniswe kubva kune hutsva: kutanga, kuvandudza mutemo, kuwedzera rutsigiro rwemari, uye kuvaka nekuvandudza zvivakwa zvakaita semigwagwa, tambo dzetambo, uye masiraidhi munzvimbo dzesango. Chechipiri, kuvandudzwa kwemidziyo yekutema, kunyanya kushandiswa kwakakura kwemichina yekutema neotomatiki uye nehungwaru, ichavandudza zvakanyanya kugadzirwa kwevashandi uye kuderedza mitengo. Chechitatu, modhi innovation, munzvimbo dzine zvakanaka zviwanikwa zvekushandisa, kuronga uye kuvaka bamboo kugadzirisa maindasitiri mapaki, kuwedzera maindasitiri ketani uye kukudza ketani yekugadzira, kunyatsowana kuzara kwemhando yekushandiswa kwe bamboo zviwanikwa, uye kuwedzera mabhenefiti ehupfumi eindasitiri ye bamboo. Chechina, sainzi uye hunyanzvi hwekuvandudza tekinoroji, wedzera mhando dzezvigadzirwa zvekugadzira bamboo, senge bamboo zviumbwa, mapuranga eshenjere, kudzika kwakadzika kwemashizha emushenjere, kudzika kwakadzika kwe bamboo chips (node, bamboo yero, bamboo bran), kukosha kwekushandiswa kwe lignin, uye kuwedzera chiyero chekushandiswa kweselulosi (kunyungudutsa pulp); gadzirisa akakosha tekinoroji mabhodhoro mukugadzira bamboo pulp nenzira yakanangwa uye ziva kuvandudzwa kwehunyanzvi hwepamba nemidziyo. Kune mabhizinesi, nekugadzira zvigadzirwa zvitsva zvakasiyaniswa zvekupedzisira zvakaita sekunyungudutsa pulp, pepa reimba, uye pepa rekurongedza chikafu, uye kusimbisa iyo yakakwirira-yakawedzera kukosha-yakawedzera kushandiswa kwefiber tsvina mukugadzira, inzira inoshanda yekubuda mumhando yepamusoro-purofiti nekukurumidza uye uwane kusimudzira kwemhando yepamusoro.
