Sida loo farsameeyo cawska sarreenka ee wax soo saarka waraaqaha

Waraaqaha casriga ah ee wax soo saarka, alaabta ceeriin ee ugu badan ee la isticmaalo waa waraaqaha qashinka ah iyo saxarka bikrada, laakiin mararka qaarkood waraaqaha qashinka ah iyo saxarka bikradu lagama heli karo meelaha qaarkood, way adag tahay in la helo ama kharash aad u badan si loo iibsado, kiiskan, soo saaraha ayaa tixgelin kara u isticmaal caws qamadi ah alaab ceeriin ah si aad waraaqo u soo saartid, cawska qamadigu waa wax soo saarka beeraha ee caadiga ah, kaas oo ay fududahay in la helo, xaddi badan iyo kharash yar.

Marka la barbar dhigo fiber alwaax ah, fiber caws qamadi waa aad u qallafsan oo daciif ah, ma fududa in la nadiifiyo caddaan, sidaas darteed inta badan, cawska qamadiga ayaa inta badan loo isticmaalaa in lagu soo saaro warqad foori ama jiingado, qaar ka mid ah warshadda waraaqaha ayaa sidoo kale isku qasan saxarka cawska qamadida iyo saxarka bikrad ah ama warqad qashin ah si ay u soo saaraan waraaqo unug tayo hoose leh ama warqad xafiis, laakiin warqad foori ama warqad jiingado ayaa loo arkaa inay yihiin alaabta ugu jecel, sababtoo ah habka wax soo saarka waa mid aad u fudud oo kharashka wax soo saarku waa yar yahay.

Si loo soo saaro warqad, caws qamadi ah ayaa loo baahan yahay in la gooyo marka hore, dhererka 20-40mm ayaa la door bidaa, aad u fudud in caws lagu wareejiyo ama lagu qaso kiimikooyinka karinta, mashiinka qamadiga ah ayaa codsanaya inuu qabto shaqada, laakiin isbeddelka warshadaha beeraha ee casriga ah, sarreenka waxaa si caadi ah u goosan by mishiinada, kiiskan, mishiinka goynta looma tixgeliyo lagama maarmaan. Ka dib marka la gooyo, cawska sarreenka ayaa loo wareejin doonaa si loogu daro kiimikooyinka karinta, habka karinta soodhaha ee caustic ayaa inta badan loo isticmaalaa habkan, si loo xaddido kharashka karinta, biyaha dhagaxa lime ayaa sidoo kale la tixgelin karaa. Ka dib markii cawska sarreenku si fiican loogu qaso kiimikooyinka wax lagu kariyo, waxaa loo wareejin doonaa dheef-shiid kiimikaad wareegsan ama barkad wax lagu kariyo oo dhulka hoostiisa ah, wax yar oo wax lagu kariyo, barkadda wax lagu karsado ee dhulka hoostiisa ayaa lagula talinayaa, dhismaha shaqada madaniga ah, kharash yar, laakiin waxtarka hoose. Awoodda wax-soo-saarka sare, waxay u baahan tahay inaad tixgeliso inaad isticmaasho dheef-shiid kiimikaad wareega ama qalabka karinta ee isku xiran, faa'iidada ayaa ah waxtarka karinta, laakiin dabcan, qiimaha qalabku aad ayuu u sarreeyaa. Barkadda wax lagu karsado ee dhulka hoostiisa ah ama dheef-shiid kiimikaad wareegsan waxay ku xiran tahay uumiga kulul, iyadoo kor u kaca heerkulka weelka ama haanta iyo isku darka wakiilka karinta, lignin iyo fiber-ka ayaa la kala saari doonaa midba midka kale. Ka dib habka karinta, cawska qamadida ayaa laga soo dejin doonaa weelka wax lagu kariyo ama haanta wax lagu karsado oo la geeyo weelka wax lagu karsado ama taangiga wasakhda ah ee diyaarka u ah in laga soo saaro fiber-ka, mashiinka sida caadiga ah loo isticmaalo waa mashiinka bleaching, mashiinka dhaqidda saxarka xawaaraha sare leh ama bivis extruder, ilaa markaas caws qamadida fiber si buuxda ayaa loo soo saari doonaa, ka dib habka sifaynta iyo baaritaanka, waxaa loo isticmaali doonaa in lagu sameeyo warqad. Wax soo saarka warqadda ka sokow, fiber cawska sarreenku waxa kale oo loo isticmaali karaa samaynta saxaarad alwaax ah ama qaabaynta saxaaradda ukunta.
