Bagasse yog dab tsi?
Bagasse muaj peb qhov tshwm sim ntawm cov nroj tsuag fibers:cellulose (45-55%), uas muab cov qauv rigidity;hemicellulose (20-25%), uas ntxiv yooj; thiablignin (18-24%), ib tug natural polymer uas pab kom sov stability thiab dej tsis kam. Cov ntsiab lus lignin yog vim li cas bagasse tuav cov zaub mov kub, roj zoo dua li daim ntawv dawb - thiab vim li cas nws tuaj yeem tiv taus qhov kub ntawm microwave uas yuav deform PLA.
Thaum cov ntawv ntim khoom hais tias "bagasse," lawv yuav luag ib txwm txhais tau hais tias qab zib bagasse, uas suav nrog ntau dua 80% ntawm kev tsim khoom thoob ntiaj teb. Agave bagasse - cov byproduct ntawm tequila ntau lawm - yog structurally zoo sib xws tab sis tsim nyob rau hauv ntau me me ntim nrog tsawg daim ntawv thov kev lag luam.
Bagasse Ua li cas?
Cov txheej txheem tsim khoom piav qhia ntau yam ntawm bagasse tus cwj pwm hauv cov khoom tiav.
Kauj ruam 1 - Sau thiab thauj:Qab Zib raug txiav thiab xa mus rau mills, feem ntau hauv 24-48 teev.
Kauj ruam 2 - Kua txiv extraction:Heavy rollers tsoo cov stalks kom rho tawm sucrose- cov kua txiv hmab txiv ntoo nplua nuj, tawm hauv qab bagasse nyoos ntawm kwv yees li 50% noo noo.
Kauj Ruam 3 - Qhuav:Lub fibrous pulp yog qhuav ua ntej nkag mus rau ib qho ntawm peb txoj kev ua haujlwm:
- Moulded fiber ntau(phaj, tais, ntim) - re-pulped hauv dej, tsim nyob rau hauv pwm nyob rau hauv tshav kub thiab siab
- Kev tsim cov ntawv pulp- chemically los yog mechanically pulped rau cais cellulose fibers
- Bioenergy- hlawv raws li cov roj boiler, feem ntau ua rau lub zog ntawm lub tshuab qab zib nws tus kheej
