Dab tsi yog cov txheej txheem tshwj xeeb ntawm Straw pellet tshuab thaum ua haujlwm?
Jun 24, 2024
Lub tshuab straw pellet siv lub hauv paus ntsiab lus ntawm kev sib cuam tshuam ntawm extrusion quab yuam thiab kev sib txhuam ntawm lub log nias thiab pwm los ua cov khoom siv. Tsis muaj additives lossis binders yog xav tau thaum lub sij hawm ua cov khoom. Straw thiab lwm yam ntaub ntawv muaj ib tug npaum li cas ntawm cellulose thiab lignin. Lignin yog cov qauv monomer nyob rau hauv cov khoom thiab phenylpropane-hom polymer compound. Nws muaj lub luag haujlwm ntawm kev ntxiv dag zog rau phab ntsa ntawm tes thiab kev sib txuas ntawm cellulose. Lignin yog cov khoom siv uas tsis yog crystalline. Qhov tseem ceeb ntawm nws yog insoluble nyob rau hauv tej yam hnyav ntawm chav tsev kub. Nws tsis muaj melting point tab sis softening point. Thaum qhov kub thiab txias nce mus txog ib qho nqi, qhov softening thiab bonding quab yuam ntawm lignin nce, thiab nyob rau hauv ib lub siab, cov cellulose molecular pawg yog dislocated, deformed, thiab ncua, thiab cov nyob ib sab biomass hais nyob rau hauv yog meshed nrog ib leeg, recombined, thiab nias rau hauv cov duab.
Yog li dab tsi yog cov txheej txheem tshwj xeeb ntawm straw pellet tshuab hauv kev ua haujlwm?
Cov txheej txheem ntws ntawm straw pellet tshuab suav nrog: thawj zaug crushing straw, tom qab ntawd kev kho mob microbial (yog tias tsis kho microbial, nws kuj tuaj yeem ua tiav ncaj qha, tab sis cov ntsiab lus ntawm cov protein tsis tuaj yeem nce ntxiv. los ntawm ntau tshaj 3 zaug.
Vim tias lub tshuab straw pellet tsis yooj yim rau kev tsim, lub tshuab pellet ntawm cov txheej txheem ib txwm yuav muaj teeb meem xws li pwm, kev puas tsuaj yooj yim ntawm kev coj tus kheej, cov khoom siv nyuaj tsim, thiab kev thaiv pwm loj. Ntawm ib sab, ntau lub tuam txhab tsis muaj lawv cov thev naus laus zis tab sis tsuas yog ua raws li qhov muag tsis pom, thiab ntawm qhov tod tes, lawv tsis kam nqis peev, cov cuab yeej siv thev naus laus zis yog qhov qub, thiab cov khoom siv tsis tsim nyog. Siv lub tshuab straw pellet tuaj yeem ua kom muaj txiaj ntsig zoo ntawm cov straws thiab ua kom yooj yim cia.
