Dab tsi yog Txoj Cai ntawm Biomass Pellet Tshuab?

Cov straw roj forming tshuab txais lub hauv paus ntsiab lus ntawm kev sib cuam tshuam ntawm lub tiaj tus module thiab lub siab lub log thiab lub extrusion quab yuam thiab tuag qhov sib txhuam los tsim cov khoom.

Cov khoom siv tsis tas yuav ntxiv cov additives lossis binders thaum ua. Cov ntaub ntawv xws li straw muaj qee qhov ntawm cellulose thiab lignin. Lignin yog cov qauv monomer hauv cov khoom siv thiab yog phenylpropanoid-hom polymer compound. Nws muaj kev ua haujlwm ntawm cov phab ntsa ntawm tes thiab khi cellulose.

Lignin yog amorphous, thiab nws qhov tseem ceeb yog insoluble nyob rau hauv ib qho hnyav ntawm chav tsev kub. Nws tsis muaj melting point, tab sis muaj ib tug softening point. Thaum qhov kub nce mus txog ib qho nqi, lignin softens thiab lub zog sib txuas ntxiv, thiab nyob rau hauv ib qho kev txiav txim, cov cellulose molecular pawg yog dislocated, deformed, thiab txuas ntxiv. Cov khoom siv biomass uas nyob ib sab hauv yog meshed nrog ib leeg, reassembled, thiab nias rau hauv cov duab. .Kev yuav khoom ntawm biomass molding tshuab khoom yog ib qho ntawm cov haujlwm txhawb nqa los ntawm lub xeev, thiab nws qhov kev cia siab yog qhov tseem ceeb.
