Koj puas tau hnov dua txog cov khoom siv pov tseg uas lwj thiab cov khoom siv lwj tau? Lawv qhov zoo yog dab tsi? Cia peb kawm txog cov khoom siv raw ntawm cov suab thaj qab zib!
Feem ntau cov khoom siv pov tseg hauv peb lub neej muaj nyob rau hauv peb lub neej. Vim yog qhov zoo ntawm tus nqi qis thiab yooj yim, tus cwj pwm ntawm "siv yas" tseem muaj txawm tias nyob rau hauv cov kev txwv thiab kev txwv yas niaj hnub no. Tab sis tam sim no nrog kev txhim kho ntawm kev paub txog ib puag ncig thiab kev nrov ntawm lub neej carbon tsawg, cov khoom siv pov tseg tau maj mam nyob hauv txoj haujlwm hauv kev ua lag luam, thiab cov khoom siv suab thaj yog ib qho ntawm lawv.
Cov kua txiv qaub ntsuab yog ib hom ntawv ua los ntawm cov kua txiv qaub ntsuab. Cov khoom siv los ntawm cov bagasse uas tau muab zom ua suab thaj. Nws yog cov tais diav ua los ntawm cov kauj ruam ntawm kev zom, yaj, zom, zom, molding, trimming, tua kab mob, thiab cov khoom tiav. Cov kua txiv qaub ntsuab yog cov fiber nruab nrab thiab ntev nrog qhov zoo ntawm lub zog nruab nrab thiab kev tawv nruab nrab, thiab tam sim no yog cov khoom siv raw tsim nyog rau kev zom cov khoom.
Cov khoom ntawm cov fibers bagasse tuaj yeem sib koom ua ke los ua ib lub network nruj, uas tuaj yeem siv los ua cov thawv noj su rau tib neeg. Hom tshiab ntawm cov tais diav ntsuab no muaj qhov nyuaj zoo thiab tuaj yeem ua tau raws li qhov xav tau ntawm kev ntim khoom noj thiab kev khaws cia zaub mov hauv tsev. Cov khoom siv muaj kev nyab xeeb, tuaj yeem lwj tau ntuj, thiab tuaj yeem lwj mus ua cov organic hauv ib puag ncig ntuj.
Cov organic no feem ntau yog carbon dioxide thiab dej. Yog tias cov khoom seem uas peb feem ntau noj yog composted nrog hom lub thawv noj su no, nws puas yuav txuag sijhawm rau kev cais cov khib nyiab? Tsis tas li ntawd, cov bagasse qab zib kuj tseem tuaj yeem ua composted ncaj qha hauv lub neej txhua hnub, ua tiav los ntawm kev ntxiv cov kab mob decomposing agent, thiab muab tso rau hauv cov lauj kaub paj kom cog paj. Bagasse tuaj yeem ua rau cov av xoob thiab ua pa tau thiab txhim kho qhov acidity thiab alkalinity ntawm cov av.
Cov txheej txheem tsim cov khoom siv hauv cov khoom qab zib yog cov nroj tsuag fiber molding. Ib qho ntawm nws cov txiaj ntsig yog qhov siab plasticity. Yog li ntawd, cov khoom siv hauv cov khoom qab zib tuaj yeem ua tau raws li cov khoom siv hauv tsev neeg thiab kev sib sau ua ke ntawm cov txheeb ze thiab cov phooj ywg. Thiab nws kuj tseem yuav siv rau qee lwm cov xov tooj ntawm tes zoo, cov thawv ntim khoom plig, cov tshuaj pleev ib ce thiab lwm yam ntim.
Cov khoom siv ua los ntawm cov suab thaj qab zib tsis muaj kuab paug thiab tsis muaj khib nyiab hauv cov txheej txheem tsim khoom. Kev tshuaj xyuas kev nyab xeeb thiab kev siv cov khoom zoo yog raws li tus qauv, thiab ib qho ntawm cov ntsiab lus tseem ceeb ntawm cov khoom siv ua los ntawm cov suab thaj qab zib yog tias nws tuaj yeem ua kom sov hauv lub qhov cub microwave (120 °) thiab tuaj yeem tuav 100 ° dej kub, tau kawg, kuj tuaj yeem tso rau hauv lub tub yees.
Nrog kev hloov kho tas mus li ntawm cov cai tiv thaiv ib puag ncig, cov ntaub ntawv lwj tau maj mam qhib cov cib fim tshiab hauv kev ua lag luam, thiab cov khoom siv hauv chav ua noj uas zoo rau ib puag ncig thiab lwj yuav maj mam hloov cov khoom yas yav tom ntej.
