Saamaynta nadiifinta saxarka ee tayada warqadda

Nadiifnimada saxarka waxaa loola jeedaa heerka xaddiga cellulose iyo xaddiga wasakhda ku jirta saxarka. Saxarada ugu habboon waa inay qani ku tahay cellulose, halka waxa ku jira hemicellulose, lignin, dambas, waxyaabaha soo saara iyo qaybaha kale ee aan cellulose ahayn ay tahay inay ahaadaan kuwo hooseeya intii suurtogal ah. Waxyaabaha ku jira cellulose waxay si toos ah u go'aamiyaan daahirnimada iyo qiimaha isticmaalka saxarka, waana mid ka mid ah tilmaamayaasha asaasiga ah ee lagu qiimeeyo tayada saxarka. Astaamaha saxarka saafiga ah ee sare:

(1) cimri dherer sare, cellulose waa qaybta ugu weyn ee ka kooban xoogga warqadda, saxarka saafiga ah ee sare macnaheedu waa ka kooban cellulose oo sarreeya, sidaa darteed warqadda la sameeyay waxay leedahay iska caabin ilmo oo xooggan, iska caabin laablaab ah iyo sifooyin kale oo jireed iyo farsamo, taasoo dheereyneysa cimriga adeegga warqadda.
(2) Xidhmo xooggan oo leh xadhkaha cellulose-ka saafiga ah ayaa samayn kara shabakad isku xidhan oo isku xidhan oo u dhaxaysa warqadda si kor loogu qaado isku xidhka gudaha, si warqadda aanay u fududayn in la kala furfuro ama la jabiyo marka la mariyo xoogagga dibadda, si loo xoojiyo xoogga guud ee warqadda.
(3) cadaan badan, joogitaanka wasakhda badanaa waxay saameysaa cadaanka iyo dhalaalka warqadda. Saxarada saafiga ah ee sare, sababtoo ah ka saarista inta badan wasakhda midabka leh, waxay ka dhigaysaa warqadda mid cadaan dabiici ah oo sare leh, taas oo ku habboon daabacaadda, qorista iyo baakadaha, iwm, waxayna kor u qaadaysaa saameynta muuqaalka ee badeecada.
(4) sifooyinka dahaarka korontada oo ka wanaagsan, cellulose waxay leedahay sifooyin dahaar wanaagsan, halka qaybaha aan ahayn cellulose ee saxarka, sida lignin, ay ka koobnaan karaan walxo gudbiya ama hygroscopic, taasoo saameyn ku yeelanaysa dahaarka korontada ee warqadda. Sidaa darteed, warqadda laga sameeyay saxarka saafiga ah waxay leedahay codsiyo badan oo ku saabsan injineernimada korontada, sida warqadda dahaarka fiilada, warqadda capacitor-ka, iwm.
Diyaarinta saxarka saafiga ah ee sare, warshadaha casriga ah ee warqadda waxay adeegsadaan habab kala duwan oo saxarka sare ah, sida saxarka kiimikada (oo ay ku jiraan saxarka sulphate, saxarka sulphite, iwm.), saxarka farsamada (sida saxarka farsamada ee kulaylka lagu shiido TMP) iyo saxarka farsamada kiimikada (CMP) iwm. Hawshani waxay hagaajisaa daahirnimada saxarka iyagoo ka saaraya ama beddelaya qaybaha aan cellulosic ahayn ee walxaha ceeriin ah.
Saxarka saafiga ah ee sare waxaa si weyn loogu isticmaalaa meelo badan sida warqadda dhaqanka ee heerka sare ah, warqadda baakadaha, warqadda takhasuska leh (tusaale ahaan, warqadda dahaarka korontada, warqadda shaandhada, warqadda caafimaadka, iwm.) iyo warqadda guriga, taasoo buuxisa heerka sare ee tayada warqadda ee ay u baahan yihiin warshadaha kala duwan.

Warqadda Yashi waxay ka samaysan tahay oo keliya 100% saxarka bamboo bikro ah, faybar ci bamboo ah oo hal mar la isticmaalo, taas oo ah doorashada ugu fiican ee saafinimada sare iyo warqadda guriga ee tayada sare leh.
