Vim li cas cov khoom qab zib bagasse thiaj li nrov?
Nrog rau txoj kev loj hlob ntawm kev lag luam hauv ntiaj teb, qhov tseem ceeb ntawm kev siv lub zog kom zoo, txo kev ua qias tuaj ib puag ncig, txo qhov zaus ntawm kev nyab xeeb ntau lawm, tiv thaiv ib puag ncig thaum muaj xwm txheej ceev, thiab ua kom muaj kev nyab xeeb ntawm lub neej tau dhau los ua qhov tseem ceeb.
Nyob rau hauv xyoo tas los no, nrog kev tso tawm ntawm "txheej txheem yas" thiab kev txhawb nqa kev tiv thaiv ib puag ncig, tib neeg txoj kev paub txog kev tiv thaiv ib puag ncig tau maj mam ntxiv dag zog, thiab kev txhim kho kev cia siab ntawm bagasse su boxes yuav zoo dua thiab zoo dua.Niaj hnub no peb tham txog vim li cas cov khoom qab zib bagasse thiaj li nrov hauv ntiaj teb.
Qab zib bagasse yog dab tsi?
Bagasse yog ib yam khoom los ntawm cov khoom qab zib thiab cov khoom siv raw rau cov ntawv fibers.Qab Zib yog cov qia zoo li cov nroj tsuag fibers uas loj hlob hauv ib xyoos.Qhov nruab nrab fiber ntau ntev yog 1.47-3.04mm, thiab bagasse fiber ntev yog 1.0-2.34mm, uas zoo ib yam li cov dav-leaved fiber ntau.Bagasse yog ib qho khoom siv zoo rau kev ua ntawv.
Bagasse yog cov nyom fiber ntau.Nws yog ib qho yooj yim mus ua noj thiab blanch.Nws siv cov tshuaj tsawg dua thiab muaj cov silicon tsawg dua li ntoo, tab sis tsawg dua li lwm cov nyom fiber ntau raw cov ntaub ntawv.Yog li ntawd, bagasse pulping thiab alkali rov qab technology thiab cov cuab yeej yog cov paub tab thiab yooj yim dua li lwm cov straw fiber raw cov ntaub ntawv.Yog li bagasse yog ib qho khoom siv pheej yig dua rau pulping.
Cov lag luam yuav tsum siv cov peev txheej txuas ntxiv sai sai.Bagasse siv cov pa hluav taws xob tsawg dua, uas yuav pab txo kom lub ntiaj teb sov.Nws xav tau lub zog tsawg dua los ua vim nws tsuas yog cov fiber ntau tshuav los ntawm kev ua suab thaj.
Dab tsi ntxiv, nws ruaj khov thiab tiv thaiv qhov kub thiab txias, uas ua rau nws muaj txiaj ntsig zoo hauv cov neeg siv khoom.
Bagasse khw
Kev tshawb fawb qhia tias molded pulp ntim lag luam tuaj yeem tshaj $ 4.3 nphom los ntawm 2026.
Tam sim no yog lub sij hawm los saib mus rau hauv qhov muaj txiaj ntsig tiag tiag rau kev tsim cov khoom lag luam moulded pulp, qab zib pov tseg.Peb muaj kev nkag tau mus rau lwm txoj kev ruaj ntseg dua vim hais tias qab zib yog cov khoom noj khoom haus loj hlob sai.
Kev xaiv ntse dua.
Kev siv cov pov tseg ua liaj ua teb yog qhov kev xaiv zoo dua.Cov khoom pov tseg no twb tau tsim tawm, tsis yog tshwj xeeb cog zoo li ntoo, uas yuav siv sijhawm ntau xyoo los loj hlob.Piv nrog rau daim ntawv, bagasse kuj xav tau ntau cov tswv yim tsawg dua los tsim cov khoom sib xws.
Qhov no yog lub sijhawm tsis pom zoo thaum tab tom nrhiav kev ntim khoom zoo tiag tiag.Muaj txog 80 lub teb chaws tsim cov suab thaj thiab muaj peev xwm zoo rau kev siv cov fibers residue hu ua bagasse.
Cov txiaj ntsig tseem ceeb ntawm bagasse muaj xws li:
Microwave thiab qhov cub nyab xeeb
Muaj peev xwm tuav cov kua dej kub txog li 120 degrees Celsius
Qhov cub muaj kev nyab xeeb txog li 220 degrees Celsius.
Environmentally phooj ywg noj su lub thawv ua los ntawm biodegradable cov ntaub ntawv, tag nrho biodegradable cov ntaub ntawv, biodegradable granules, starch biodegradable cov ntaub ntawv thiab lwm yam ntaub ntawv yuav ua kom tiav thiab sai degraded nyob rau hauv cov av thiab ntuj ib puag ncig raws li tsim nyog, tsis muaj tshuaj lom, tsis muaj kuab paug, thiab tsw- dawb.Nws yuav tsis rhuav tshem cov qauv av, thiab ua tiav "los ntawm xwm, tab sis kuj nyob rau hauv xwm", uas yog ib qho zoo dua hloov rau cov yas thiab ntawv ntim.
