● Habka sameynta warqadda saxarka bamboo
Tan iyo markii uu si guul leh u horumaray warshadaha iyo isticmaalka bamboo, habab badan oo cusub, teknoolojiyad iyo badeecooyin loogu talagalay habaynta bamboo ayaa soo ifbaxay midba midka kale ka dib, taas oo si weyn u hagaajisay qiimaha isticmaalka bamboo. Horumarinta tignoolajiyada bamboo ee farsamaysan ee Shiinaha ayaa ka gudubtay habka gacanta ee dhaqameed waxayna isu beddeshay qaab wax soo saar warshadeed iyo warshadeed. Hababka wax soo saarka bamboo ee caanka ah ee hadda jira waa farsamo, kiimiko iyo kiimiko farsamo. Saxarada bamboo ee Shiinaha inta badan waa kiimiko, oo ka dhigan qiyaastii 70%; farsamada kiimikada ayaa ka yar, ka yar 30%; isticmaalka hababka farsamada si loo soo saaro saxarka bamboo waxay ku kooban tahay marxaladda tijaabada, mana jirto warbixin warshadeed oo baaxad weyn leh.
1. Habka xinjirowga farsamada
Habka loo isticmaalo saxarka farsamada waa in lagu shiido xabagta fiilooyinka iyadoo la adeegsanayo habab farsamo iyada oo aan lagu darin walxo kiimiko ah. Waxay leedahay faa'iidooyinka wasakhowga hooseeya, heerka saxarka sare iyo habka fudud. Xaaladda xakamaynta wasakhowga oo sii kordheysa iyo yaraanta kheyraadka saxarka alwaaxa ee dalka, saxarka farsamada ee saxarka bamboo ayaa si tartiib tartiib ah u qiimeeyay dadku.
In kasta oo xoqidda farsamada ay leedahay faa'iidooyinka heerka sare ee xoqidda iyo wasakhowga hooseeya, haddana waxaa si weyn loogu isticmaalaa warshadaha qodista iyo sameynta waraaqaha ee walxaha coniferous sida spruce. Si kastaba ha ahaatee, sababtoo ah maaddada sare ee lignin, dambas, iyo 1% soosaarka NAOH ee ku jira halabuurka kiimikada ee bamboo, tayada saxarka waa mid liidata waana ay adag tahay in la buuxiyo shuruudaha tayada ee warqadda ganacsiga. Codsiga warshaduhu waa naadir wuxuuna inta badan ku jiraa marxaladda cilmi-baarista sayniska iyo sahaminta farsamada.
2. Habka kiimikada ee nuugista
Habka kiimikada ee loo isticmaalo bamboo waa walxo ceeriin ah waxayna isticmaashaa habka sulfate ama habka sulfite si loo sameeyo saxarka bamboo. Alaabada ceeriin ee bamboo waa la baaraa, la dhaqaa, la fuuq-baxaa, la kariyaa, la sifeeyaa, la miiraa, la dhaqaa ka hortagga current-ka, la xidhaa, la sifeeyaa oksijiinta, la caddeeyaa iyo habab kale si loo sameeyo saxarka bamboo. Habka kiimikada ee loo isticmaalo saxarka bamboo wuxuu ilaalin karaa faybarka wuxuuna hagaajin karaa heerka saxarka. Saxaarka la helay waa mid tayo wanaagsan leh, nadiif ah oo jilicsan, si fudud loo caddeeyo, waxaana loo isticmaali karaa in lagu soo saaro warqad qoraal oo heer sare ah iyo warqad daabacan.
Sababtoo ah ka saarista xaddi badan oo lignin, dambas iyo soosaarro kala duwan habka xinjirowga ee habka xinjirowga kiimikada, heerka xinjirowga ee xinjirowga bamboo waa mid hooseeya, guud ahaan 45% ~ 55%.
3. Kiimikada Farsamo ee Buufinta
Soo saarista Kiimikada ee Mechanical Pulping waa hab soo saarista ul oo u adeegsada bamboo sidii walxo ceeriin ah isla markaana isku daraya qaar ka mid ah astaamaha soo saarista kiimikada iyo soo saarista farsamada. Soo saarista Kiimikada ee Mechanical Pulping waxaa ka mid ah habka nus-kiimikada, habka farsamada kiimikada iyo habka thermomechanical ee kiimikada.
Xabagta iyo sameynta warqadaha, heerka xabagta ee xabagta kiimikada ayaa ka sarreeya tan xabagta kiimikada, taasoo guud ahaan gaari karta 72% ~ 75%; tayada xabagta laga helo xabagta kiimikada ayaa aad uga sarreysa tan xabagta farsamada, taas oo dabooli karta shuruudaha guud ee wax soo saarka warqadda badeecadaha. Isla mar ahaantaana, kharashka soo kabashada alkali iyo daaweynta wasakhda ayaa sidoo kale u dhexeeya xabagta kiimikada iyo xabagta farsamada.
▲ Khadka Soo-saarka Buufinta Bamboo
● Qalabka Samaynta Warqadaha Bamboo Saxarada
Qalabka qaybta sameynta ee khadka wax soo saarka waraaqaha bamboo waa isku mid sida khadka wax soo saarka saxarka alwaaxa. Farqiga ugu weyn ee qalabka sameynta waraaqaha bamboo wuxuu ku jiraa qaybaha diyaarinta sida jarista, dhaqidda iyo karinta.
Maadaama bamboo uu leeyahay qaab-dhismeed godan, qalabka jarista ayaa ka duwan kan qoryaha. Qalabka jarista bamboo ee caadiga ah ee loo isticmaalo waxaa ugu horreyn ka mid ah jarista bamboo ee duuban, jarista bamboo ee saxanka iyo jarista durbaanka. Jarjarrada bamboo ee duuban iyo jarista bamboo ee saxanka saxanka leh waxay leeyihiin hufnaan shaqo oo sare, laakiin tayada jajabyada bamboo ee la farsameeyay (qaabka jajabka bamboo) ma fiicna sida kuwa jajabyada durbaanka. Isticmaalayaashu waxay dooran karaan qalabka jarista (jeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeexjeax ...
Qalabka dhaqidda jajabka bamboo ayaa loo isticmaalaa in lagu saaro wasakhda, waxaana laga soo sheegay Shiinaha alaabooyin badan oo shati haysta. Guud ahaan, dhaqidda saxarka faakuumka, dhaqidda saxarka cadaadiska iyo dhaqidda saxarka suunka ayaa la isticmaalaa. Shirkadaha dhexdhexaadka ah iyo kuwa waaweynba waxay isticmaali karaan dhaqidda saxarka ee cusub ee laba-roller ah ama dhaqidda saxarka ee adag ee biyaha ka saara.
Qalabka karinta jajabka bamboo waxaa loo isticmaalaa jilcinta jajabka bamboo iyo kala soocida kiimikada. Shirkadaha yaryar iyo kuwa dhexdhexaadka ah waxay isticmaalaan dheriyo karinta toosan ama makiinadaha karinta joogtada ah ee tuubada toosan. Shirkadaha waaweyn waxay isticmaali karaan makiinadaha karinta joogtada ah ee Camille oo leh dhaqidda faafinta si loo hagaajiyo waxtarka wax soo saarka, wax soo saarka saxarkana sidoo kale wuu kordhi doonaa si waafaqsan, laakiin waxay kordhin doontaa kharashka maalgashiga hal mar.
1. Samaynta warqadaha saxarka bamboo waxay leedahay awood weyn
Iyada oo lagu saleynayo sahanka kheyraadka bamboo ee Shiinaha iyo falanqaynta ku habboonaanta bamboo lafteeda sameynta waraaqaha, horumarinta xooggan ee warshadaha bamboo-ka ma yareyn karto oo keliya dhibaatada agabka ceeriin ee alwaaxa adag ee warshadaha warqadda Shiinaha, laakiin sidoo kale waxay noqon kartaa hab wax ku ool ah oo lagu beddelo qaab-dhismeedka alaabta ceeriin ee warshadaha sameynta waraaqaha iyo in la yareeyo ku tiirsanaanta jajabyada alwaaxa ee dibadda laga keeno. Qaar ka mid ah culimada ayaa falanqeeyay in qiimaha halbeegga ee saxarka bamboo halkii halbeeg uu ka hooseeyo 30% kan geed, spruce, eucalyptus, iwm., tayada saxarka bamboo-kana ay la mid tahay saxarka alwaaxa.
2. Is-dhexgalka warqadda kaynta waa jihada horumarinta muhiimka ah
Iyada oo ay ugu wacan tahay faa'iidooyinka koritaanka degdega ah iyo dib-u-soo-nooleynta ee bamboo, xoojinta beerista kaymaha gaarka ah ee bamboo ee si degdeg ah u koraya iyo sameynta saldhig wax soo saar bamboo ah oo isku dara kaymaha iyo warqadda ayaa noqon doona jihada horumarinta waara ee warshadaha saxarka iyo warqadda ee Shiinaha, yaraynta ku tiirsanaanta jajabyada alwaaxa ee dibadda laga keeno iyo saxarka, iyo horumarinta warshadaha qaranka.
3. Bamboo-samaynta kooxda waxay leedahay awood horumarineed oo weyn
Warshadaha hadda jira ee wax lagu farsameeyo bamboo, in ka badan 90% walxaha ceeriin ah waxaa laga sameeyaa bamboo moso (Phoebe nanmu), kaas oo inta badan loo isticmaalo soo saarista alaabta guriga iyo agabka dhismaha. Samaynta waraaqaha saxarada bamboo sidoo kale waxay inta badan u isticmaashaa bamboo moso (Phoebe nanmu) iyo bamboo cycad ah agab ceeriin ah, taas oo samaysa xaalad tartan walax ceeriin ah mana aha mid ku habboon horumarka waara ee warshadaha. Iyada oo lagu salaynayo noocyada bamboo ceeriin ah ee jira, warshadaha samaynta waraaqaha saxarada bamboo waa inay si xoog leh u horumariyaan noocyo kala duwan oo noocyada bamboo ah si loogu isticmaalo walxaha ceeriin ah, si buuxda u isticmaalaan bamboo cycad ah oo qiimo jaban, bamboo masduulaagii weynaa, bamboo dabada phoenix, dendrocalamus latiflorus iyo bamboo kale oo isku urursan si loogu sameeyo xaashida iyo warqadda, iyo in la horumariyo tartanka suuqa.
▲Bamboo isku urursan ayaa loo isticmaali karaa sidii walxo muhiim ah oo saxarka ah
