Sida loo farsameeyo cawska sarreenka ee wax soo saarka waraaqaha

Wax soo saarka waraaqaha casriga ah, alaabta ceeriin ee ugu badan ee la isticmaalo waa waraaqaha qashinka ah iyo saxarka bikrada, laakiin mararka qaarkood waraaqaha qashinka ah iyo saxarka bikrada ah lagama heli karo meelaha qaarkood, way adag tahay in la helo ama kharash aad u badan si loo iibsado, kiiskan, soo-saaruhu wuxuu tixgelin karaa inuu isticmaalo cawska qamadiga ah si uu u soo saaro warqad.

Marka la barbardhigo fiber alwaax ah, fiber caws qamadi waa aad u qallafsan oo daciif ah, ma fududa in la caddeeyo, sidaas darteed inta badan, cawska qamadiga ah ayaa inta badan loo isticmaalaa in lagu soo saaro warqad foorno ama warqad jiingado, qaar ka mid ah warshadda warqad sidoo kale qasan saxarka caws qamadi saxarka bikrad ah ama warqad qashinka si ay u soo saaraan tayo hoose warqad nudaha ama warqad xafiis, laakiin fluing warqad ama warqad jiingado ayaa loo arkaa in wax soo saarka ka yar yahay wax soo saarka.

Si loo soo saaro warqad, caws qamadi ah ayaa loo baahan yahay in marka hore la gooyo, dhererka 20-40mm ayaa la door bidaa, aad u sahlan in cawska lagu wareejiyo ama lagu qaso kiimikooyinka karinta, mashiinka qamadiga ah ayaa codsanaya inuu sameeyo shaqada, laakiin isbeddelka warshadaha beeraha ee casriga ah, qamadiga waxaa badanaa la goostaa mashiinnada, kiiskan, mashiinka wax lagu gooyo 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 kariyo ilaa weel dharbaaxo ah ama taangiga wasakhda ah ee diyaarka u ah in laga soo saaro fiber, mishiinka sida caadiga ah loo isticmaalo waa mashiinka bleaching, mashiinka dhaqidda saxarka xawaaraha sare leh ama bivis extruder, ilaa markaas fiber cawska qamadida si buuxda ayaa loo soo saari doonaa, ka dib habka nadiifinta iyo baarista, waxaa loo isticmaali doonaa in lagu sameeyo warqad. Wax soo saarka warqadda ka sokow, fiber cawska qamadiga ayaa sidoo kale loo isticmaali karaa samaynta saxaarad alwaax ah ama qaabaynta saxaaradda ukunta.
