Shiinaha waa dalka ugu badan ee noocyada bamboogu iyo heerka ugu sarreeya ee maaraynta bambooga. Iyada oo leh faa'iidooyinka kheyraadka bamboo ee qani ah iyo tignoolajiyada samaynta saxarka bamboo ee sii kordheysa ee qaan-gaadhka ah, warshadaha warqad-samaynta bamboo ayaa kor u kacaya oo xawliga isbeddelka iyo cusboonaysiinta ayaa sii kordhaya. Sannadka 2021, wax-soo-saarka saxarka bamboo ee dalkaygu wuxuu ahaa 2.42 milyan oo tan, sanad-sannad koror dhan 10.5%; waxaa jiray 23 shirkadood oo wax-soo-saar bamboo ah oo ka sarreeya cabbirka loo qoondeeyay, oo leh 76,000 oo shaqaale ah iyo qiimaha wax soo saarka ee 13.2 bilyan yuan; waxaa jiray 92 shirkadood oo farsameeya waraaqaha iyo xaashida bamboo, oo leh 35,000 oo shaqaale ah iyo wax soo saarka 7.15 bilyan yuan; waxaa jiray in ka badan 80 shirkadood oo wax-soo-saar waraaqo ah oo isticmaalaya bamboo sida alaabta ceeriin, oo ay ku jiraan ilaa 5,000 oo shaqaale ah iyo wax soo saarka qiimihiisu dhan yahay 700 milyan yuan; xawliga ciribtirka awoodda wax-soo-saarka dib-u-noqoshada ayaa la dedejiyay, iyo tikniyoolajiyada wax-soo-saarka ee kiimikaad sare leh, farsamaynta farsamaynta kiimikada ee wax-ku-oolka ah ee pre-impregnation iyo tignoolajiyada xajinta ayaa si weyn loogu isticmaalay soosaarka saxarka bamboo. Warshada samaynta xaashida bamboo ee dalkaygu waxay u socotaa casriyaynta iyo miisaanka.
Tallaabooyin cusub
Bishii Disembar 2021, Maamulka Dhirta iyo Daaqsinta ee Gobolka, Guddiga Horumarinta iyo Dib-u-habaynta Qaranka iyo 10 waaxood oo kale ayaa si wadajir ah u soo saaray "Ra'yiga ku saabsan Dardargelinta Hal-abuurka iyo Horumarinta Warshadaha Bamboo". Degaano kala duwan ayaa si isdaba joog ah u dejiyay siyaasado taageeraya si ay u bixiyaan taageero siyaasadeed oo xoogan oo lagu horumarinayo horumarinta tayada sare leh ee warshadaha bamboo, oo ay ku jiraan saxarka bamboo iyo warshadaha waraaqaha. Meelaha ugu muhiimsan ee dalkeyga saxarka bamboo-ga iyo meelaha wax-soo-saarka waraaqaha waxay ku badan yihiin Sichuan, Guizhou, Chongqing, Guangxi, Fujian iyo Yunnan. Waxaa ka mid ah, Sichuan hadda waa gobolka ugu weyn ee saxarka bamboo-ka iyo warqadaha ee dalkayga. Sanadihii la soo dhaafay, Gobolka Sichuan wuxuu si xoog leh u horumariyay koox warshadeed isku dhafan iyo waraaqo "bamboo-pulp-paper-processing- salees", abuuray calaamad hormuud u ah xaashida xaashida bamboo, waxayna u beddeshay faa'iidooyinka ilaha bamboo cagaarka ah horumarinta warshadaha faa'iidooyinka, gaaritaanka natiijooyin cajiib ah. Iyada oo ku saleysan kheyraadka bamboo ee hodanka ah, Sichuan waxay beeratay noocyo kaymo bamboo ah oo tayo sare leh, waxay hagaajisay tayada saldhigyada kaynta bamboo, kaymo bamboo ah oo lagu beeray jiirar ka badan 25 darajo iyo dhul beereed aan aasaasi ahayn oo leh qulqulo 15 ilaa 25 digrii biyo muhiim ah. Ilaha la kulma siyaasadda, si cilmiyaysan kor loogu qaaday maamulka saddex-geesoodka ah ee kaymaha bamboo, isku dubarid horumarinta kaymaha bamboo alwaax iyo kaymaha bambo ecological, iyo xoojiyeen magdhow kala duwan iyo tallaabooyinka kabka. Kaydka bamboo ayaa si joogto ah u kordhay. Sannadkii 2022, dhulka kaynta bamboo ee gobolka ayaa dhaaftay 18 milyan oo mu, taas oo siisay xaddi badan oo tayo sare leh oo fiber bamboo ceeriin ah oo loogu talagalay soo saarista bamboo iyo samaynta waraaqaha, gaar ahaan saxarka bamboo warqadaha guriga midabka dabiiciga ah. Si loo hubiyo tayada xaashida xaashida bamboo loona wanaajiyo wacyiga astaanta warqadaha midabka dabiiciga ah ee gudaha iyo dibadaba, Ururka Warshadaha Waraaqaha ee Sichuan ayaa ka codsatay Xafiiska Ganacsiga ee Xafiiska Hantida Caqliga ee Gobolka si loo diwaangeliyo "Warqada Bamboo Pulp Paper". "ganacsiga wadajirka ah. Laga soo bilaabo halgankii la soo dhaafay ee hal-gacan-ka-soo-baxa ilaa horumarka dhexe ee hadda jira iyo horumarka baaxadda leh, isu-duubnida diirimaadka iyo iskaashiga guul-guud waxay noqdeen faa'iidooyinka lagu garto horumarka Sichuan Paper. Sannadkii 2021, waxaa jiray 13 shirkadood oo bamboo ah oo ka sarreeya cabbirka loogu talagalay gobolka Sichuan, oo leh wax soo saarka saxarka bamboo ee 1.2731 milyan tan, koror sannad kasta ah 7.62%, taasoo ka dhigan 67.13% wax soo saarka saxarka bamboo ee asalka ah ee dalka, ee kaas oo qiyaastii 80% loo isticmaalay in lagu soo saaro waraaqaha guriga; waxaa jiray 58 shirkadood oo ah xaashida xaashida xaashida qoyska oo leh wax soo saarka sanadlaha ah 1.256 milyan oo tan; waxaa jiray 248 shirkadood oo ka shaqeeya waraaqaha bamboo-ga oo soo saara 1.308 milyan oo tan sanadkii. 40% xaashida saxarka bamboo-ga dabiiciga ah ee la soo saaro waxaa lagu iibiyaa gobolka, 60% waxaa lagu iibiyaa meel ka baxsan gobolka iyo dibadda iyada oo loo marayo goobaha iibka e-ganacsiga iyo hindisaha qaranka "Suunka iyo Waddada". Adduunku wuxuu Shiinaha u eegaa saxarka bamboo, Shiinuhuna wuxuu Sichuan u eegaa saxarka bamboo. Summada Sichuan "bamboo pulp paper" waxay noqotay mid caalami ah.
Farsamada cusub
Dalkaygu waa soo saaraha ugu wayn aduunka ee saxarka bamboo/bamboo millata, oo leh 12 khadadka wax soo saarka kiimikada bamboo casri ah oo leh awood wax soo saar sanadeed in ka badan 100,000 oo tan, wadarta wax soo saarka 2.2 milyan oo tan, kuwaas oo 600,000 oo tan ay yihiin millatariga bamboo saxarka. Fang Guigan, oo ah cilmi-baare iyo kormeere dhakhtar oo ka tirsan Machadka Warshadaha Kiimikada ee Kaymaha ee Akademiyada Kaymaha ee Shiinaha, ayaa muddo dheer u heellan cilmi-baarista iyo horumarinta tignoolajiyada muhiimka ah iyo qalabka warshadaha wax-soosaarka nadiifka ah ee waddankayga. Waxa uu sheegay in ka dib markii dadaalka wadajirka ah ee warshadaha, tacliinta iyo cilmi-baarista, cilmi-baarayaashu ay jebiyeen tignoolajiyada muhiimka ah ee saxarka bamboo/dirista wax soo saarka saxarka, iyo tignoolajiyada casriga ah ee karinta iyo bleaching iyo qalabka ayaa si weyn loogu isticmaalay soo saarista saxarka kiimikada bamboo. Iyada oo loo marayo isbeddelka iyo codsiga natiijooyinka cilmi-baarista sayniska iyo tignoolajiyada sida "Tiknoolajiyada Cusub ee Waxtarka Bamboo Pulping iyo Papermaking" tan iyo "Qorshaha Shanta Sano ee Laba iyo Tobnaad", dalkaygu wuxuu markii hore xalliyey dhibaatada N iyo P cusbada dheelitirka habka Silikoon ka saarida khamriga madow iyo daaweynta dheecaanka dibadda. Isla mar ahaantaana, horumar la taaban karo ayaa laga sameeyay kororka xadka cadaanka ee bamboo-soosaarka saxarka sare ee bleaching. Marka la eego xaalada qiyaasta wakiilka bleaching dhaqaale, cadaanka saxarka bamboo-soosaarka sare wuxuu ka kordhay wax ka yar 65% ilaa in ka badan 70%. Waqtigan xaadirka ah, cilmi-baarayaashu waxay ka shaqeynayaan sidii ay u jebin lahaayeen cilad farsamo sida isticmaalka tamarta sare iyo wax-soo-saarka hooseeya ee habka wax-soo-saarka bamboo, waxayna ku dadaalaan inay abuuraan faa'iidooyin kharash ah wax soo saarka saxarka bamboo iyo hagaajinta tartanka suuqa caalamiga ah ee saxarka bamboo.
Fursado cusub
Bishii Janaayo 2020, amarka cusub ee xannibaadda balaastikada ee qaranka ayaa qeexaya baaxadda xaddidaadda balaastikada iyo xulashada beddelka, taasoo u keenaysa fursado cusub shirkadaha saxarada bamboo iyo waraaqaha. Khubarada ayaa tilmaamay in marka la eego asalka "dual carbon", bamboo, oo ah kheyraad muhiim ah oo aan alwaax ahayn, ay door muhiim ah ka ciyaaraan xaqiijinta amniga qoryaha caalamiga ah, horumarinta cagaarka yar ee kaarboon, iyo hagaajinta nolosha dadka. "Ku beddelashada bacaha bamboo" iyo "ku beddelashada alwaax bamboo" waxay leeyihiin karti weyn iyo karti horumarineed oo warshadeed oo weyn. Bamboo si degdeg ah ayuu u koraa, waxa uu leeyahay bioomass weyn oo qani ku ah kheyraad. Tayada qaab-dhismeedka fiber bamboo iyo waxa ku jira cellulose waxay u dhaxaysaa alwaax fidsan iyo alwaax caleen-ballaaran, iyo saxarka bamboo ee la soo saaray waxay la mid tahay saxarka alwaax. Xadhkaha bamboodu wuu ka dheer yahay alwaax caleen-ballaaran, qaab-dhismeed yar oo gidaarka unuggu waa mid gaar ah, xoogga garaaca iyo ductility waa wanaagsan yahay, saxarka la caddeeyeyna wuxuu leeyahay sifooyin muuqaal ah oo wanaagsan. Isla mar ahaantaana, bamboodu waxay leedahay maaddo cellulose sare leh waana walxo ceeriin oo fibre ah oo aad u fiican oo loogu talagalay samaynta waraaqaha. Sifooyinka kala duwan ee saxarka bamboo iyo saxarka alwaax waxaa loo isticmaali karaa in lagu soo saaro waraaqo iyo waraaqo kala duwan oo heer sare ah. Fang Guigan ayaa sheegay in horumarinta joogtada ah ee saxarka bamboo iyo warshadaha waraaqaha ay yihiin kuwo aan ka go'in hal-abuurka: marka hore, hal-abuurka siyaasadda, kordhinta taageerada maaliyadeed, iyo dhisidda iyo horumarinta kaabayaasha sida waddooyinka, xargaha xargaha, iyo slides ee meelaha kaynta bamboo. Midda labaad, hal-abuurnimada qalabka wax lagu gooyo, gaar ahaan adeegsiga balaadhka ah ee iswada iyo qalabka wax lagu gooyo ee caqliga leh, waxay si weyn u wanaajin doontaa wax-soo-saarka shaqada waxayna yaraynaysaa qiimaha dhimista. Seddexaad, hal-abuurka moodeelka, meelaha leh xaaladaha kheyraadka wanaagsan, qorshee oo dhisa beero warshadaynta bamboo, fidin silsiladda warshadaha oo balaadhiso silsiladda farsamaynta, si dhab ah loo gaaro ka faa'iidaysiga tayo-buuxa ee kheyraadka bamboo, iyo in la kordhiyo faa'iidooyinka dhaqaale ee warshadaha bamboo. Midda afraad, hal-abuurnimada sayniska iyo tignoolajiyada, waxay balaadhisaa noocyada alaabada habaynta bamboo, sida agabka qaab-dhismeedka bamboo, looxyada bamboo, habaynta qoto dheer ee caleemaha bamboo, farsamaynta qoto dheer ee chips bamboo (nodes, bamboo yellow, bamboo bran), ka faa'iidaysiga qiimo sare leh lignin, oo balaadhisa baaxadda codsiga cellulose (kala diri saxarka); u xalliso cilad farsamo ee muhiimka ah ee soo saarista saxarka bamboo hab bartilmaameed leh oo xaqiiji casriyaynta tignoolajiyada gudaha iyo qalabka. Shirkadaha, iyaga oo horumarinaya alaabada terminaalka cusub ee kala duwan sida milanka saxarka, xaashida guriga, iyo xaashida baakadaha cuntada, iyo xoojinta ka faa'iidaysiga qiimaha sare leh ee qashinka ah ee wax soo saarka, waa hab wax ku ool ah oo looga baxo heer sare qaabka faa'iidada sida ugu dhakhsaha badan oo loo gaaro horumar tayo sare leh.
