Xaashida bawdada ee ka samaysa Shiinaha ayaa leh taariikh dheer. Cudurka 'bamboo fiber' iyo mooyeeya kiimikada waxay leeyihiin astaamo gaar ah. Celceliska Fiber dhererkiisu waa mid dheer, oo microboot-ka darbiga loo yaqaan 'fiberka' waa mid gaar ah, oo garaacaya xoogga waxqabadka pull-ka ah waa mid wanaagsan, oo ah furfurnadda indhaha ee wanaagsan: furfurnaan badan oo iftiin leh oo kala firidhsan. Bamboo ceyriinka cee'da Lighin waxa ku jira (qiyaastii 23% illaa 32%) ayaa ka sarreeya, iyadoo la go'aaminayo karinta alkali sareeya iyo sulfide (sulfide guud ahaan 20% ilaa 25%), oo u dhaw qoryaha wareegaya; Alaabada ceyriinka, walxaha kuleylka iyo silicon-ka ayaa ka sarreeya, laakiin sidoo kale in lagu dhaqo saxarka, jirada loo yaqaan 'black' uumi baxa ashtakada ashtakoolka khamriga iyo feejignaanta qalliinka caadiga ah ee hawlgalku wuxuu soo gaadhay dhibaatooyin xoogaa. Si kastaba ha noqotee, bambaanooyinka ceyriinka ah ma aha wax fiican oo ceyriin ah oo waraaqda lagu sameeyo.
Mustaqbalka Bamboo Dhexdhexaad Dhexdhexaad ah iyo Nidaamka Kiimikada Maskaxda ee Pull Milkiilaha Maskaxda, Asal ahaan waxay isticmaali doontaa geedi socodka TCF ama geedi socodka nadiifinta ee ECF. Guud ahaan marka lagu daro, oo lagu daro qoto dheer ee sharafta iyo sharafta oksijiinta ee hubka, isticmaalka tikniyoolajiyadda TCF ama tikniyoolajiyadda 'TCF', iyadoo la raacayo tirada qaybaha shaashadda, bamboo pulls-ka waa la jeexjeexi karaa ilaa 88% ~ 90% ISO Cunness.
Isbarbardhiga bamboor ee loo yaqaan 'bambo eCF iyo dhiig-baxa TCF
Sababta oo ah caqabadda ugu sarreysa ee bamboo, waxay u baahan tahay in lagu daro khiyaano qoto dheer iyo tikniyoolajiyad hagaajinta oksijiinta si loo xakameeyo qiimaha Kappa ee slurry galka ECF iyo TCF (10), iyadoo la adeegsanayo EPH-da ee loo yaqaan 'EPF', acid Ka-hortagga ama EOP laba-marxalad laba-marxalad TCF ah oo dhan, kuwaas oo dhammaantood biliijectisan kara biliiject Sulboo Pull Pull ilaa heer sare oo ah 88% ISO.
The bleaching performance of different raw materials of bamboo varies greatly, Kappa to 11 ~ 16 or so, even with two-stage bleaching ECF and TCF, the pulp can only achieve 79% to 85% whiteness level.
Marka la barbar dhigo TCF BAMBO Pull Pull, boor-ka-boobka ee ECF waxay leedahay dhiig-qabad yar iyo viscosity sare, kaas oo guud ahaan gaari kara in ka badan 800ml / g. Laakiin xitaa ha wanaajiyey in la wanaajiyey bamboo pulp, viscosity wuxuu gaari karaa oo keliya 700ml / g. Tayada Pluqu iyo TCP ee TEFP ee Tooska ah waa xaqiiqo aan la taaban karin, laakiin tixgelinta dhameystiran ee tayada saxarka, maalgashiga iyo kharashka ku shaqeeya, bamboo pull by pull beling ama dhiig-goynta dhiigga ee ECF. Go'aannada shirkadaha kaladuwan ee kaladuwan ayaa adeegsada geedi socodyo kala duwan. Laakiin isbeddelka horumarka mustaqbalka, bamboo gacmaha loo yaqaan 'bamboo pulp pulp' iyo inflaha TCF waqti dheer ayey wada noolaan doonaan.
Taageerayaasha 'ECF's tikniyoolajiyadda ayaa rumeysan in saxarka loo yaqaan' ECF 'ay leedahay tayo wanaagsan oo saxarka, iyadoo la adeegsanayo kiimikooyin yar, hufnaan badan oo hufan, halka nidaamka qalabka uu yahay mid qaangaar ah oo deggan oo deggan. Si kastaba ha noqotee, u doodayaasha tikniyoolajiyadda tikniyoolajiyadda TCF ayaa ku doodaya in tikniyoolajiyadda dhiig-baxa TCF ay leedahay faa'iidooyinka dheecaanka wasakhda ka yar ee geedka dhiig-baxa, shuruudaha kahortaga-xudunta ee qalabka, iyo maalgashiga hoose. Khadka wax soo saarka ee 'sulphate' ee sadarka wax soo saarka ee bilaashka ah ee lagu xidho ee-xiritaanka, qiiqa bilaha wasakhda wasakhda ah ayaa lagu xakamayn karaa 5 illaa 10m3 / t proop. Qeybta wasakhda ah ee (po) Qeybta loo yaqaan 'po)' waxaa loo diraa qaybta iska dhigista oksijiinta ee loo isticmaalo, iyo wasakhda laga soo qaado qaybta dharka lagu maydho ee loo adeegsado, oo ugu dambeyntiina wuxuu galayaa alqati soo kabashada alkali.idic Sababo la xiriira dhiig-gooyayaasha oo aan lahayn koloriin, kiimikooyinku waa kuwo aan caadi ahayn, qalabka loo yaqaan 'cliting-ka' uma baahna in la isticmaalo birta iyo bir qaas ah, sidaa darteed kharashka maalgashiga ayaa hooseeya. Marka la barbar dhigo khadka waxsoosaarka TCF, ee ECF saxarada Khadadka Maalgashiga Khadadka Safka ah ee 20% ilaa 25%, iyadoo maalgashiga khadka wax soo saarka saxarka uu ka sarreeyo, maalgashiga nidaamka soo kabashada kiimikada ayaa sidoo kale ka weyn, iyo Qalliinku wuu ka adag yahay.
Marka la soo gaabiyo, bamboo pulp TCF iyo ECF ee soosaarka ee wax soo saarka u sarreeya 88% ilaa 90% si buuxda loo jeexjeexay bamboo pulp waa macquul. Qaboojiyeyaasha waa in loo adeegsadaa tikniyoolajiyadda qoto dheer, daahfurka oksijiinta ka hor intaanu nadiifinin, xakameynta saxarka nidaamka sunta ah ee qiimaha lagu isticmaalo. Soojeedin taxane ah oo loo soo jeediyay Isku xigxiga 'L-ECF' waa OD (EOP) Q (PO); Isku xigxiga marinka 'TCF' waa EOP (ZQ) (PO) (PO), O (ZQ) (PO) (ZQ) (PO) (PO). Sida iskuxirka kiimikaad (gaar ahaan lignin waxyaabaha ka kooban) iyo manphilogy-ga '' fiber-ka 'aad u kala duwan yihiin noocyo kala duwan oo bamboo ah, daraasad nidaamsan oo ah noocyada bamboo ee kala duwan ee bambo ee kala duwan ka hor dhismaha geedka si loo helo hagitaan macquul ah Wadooyinka nidaamka iyo xaaladaha.
