Bagged tshuaj yej tau tsim sai heev vim nws qhov zoo ntawm "ntau, huv si, yooj yim, thiab ceev", thiab thoob ntiaj teb bagged tshuaj yej kev lag luam tau qhia txog kev loj hlob sai.
Raws li cov khoom ntim rau tshuaj yej hnab,tshuaj yej lim ntawvyuav tsum tsis tsuas yog xyuas kom meej tias cov khoom xyaw zoo ntawm cov tshuaj yej tuaj yeem tawg sai sai rau hauv cov tshuaj yej kua zaub thaum lub sij hawm brewing, tab sis kuj tiv thaiv cov tshuaj yej hmoov hauv lub hnab los ntawm infiltrating mus rau hauv cov tshuaj yej kua zaub. Tom qab xyoo ntawm txoj kev loj hlob, cov khoom ntawm cov tshuaj yej lim ntawv tau maj mam hloov los ntawm gauze, lim ntawv, nylon, PET, PVC, PP thiab lwm yam ntaub ntawv rau pob kws fiber.
Pob kws fiber, tseem hu ua polylactic acid (PLA) fiber, yog muab los ntawm cov khoom siv txuas ntxiv mus ntxiv xws li pob kws, qos yaj ywm, thiab qoob loo straw. Nws muaj biocompatibility zoo thiab biodegradability, antibacterial zog, thiab breathability. Nws tuaj yeem tsis tsuas yog siv los ua biodegradable non-woven tshuaj yej hnab, tab sis kuj siv rau hauv cov ntaub ntawv ntub dej los tsim cov ntawv ntim khoom noj xws li tshuaj yej hnab, hnab kas fes, thiablim ntawv.
Yog li, tsom mus rau qhov ua tau zoo ntawm cov khoom siv nws tus kheej, dab tsi yog qhov zoo ntawm kev siv PLA fiber ntau hauv cov ntaub ntawv ntub dej?
1. Cov khoom siv yog ntuj thiab tuaj yeem sib cuag nrog cov khoom noj
Cov khoom siv raw ntawm polylactic acid fiber yog los ntawm cov khoom siv cog dua tshiab. Raws li cov ntaub ntawv pov thawj kev nyab xeeb khoom noj khoom haus, polylactic acid fiber ntau tuaj yeem siv dav hauv ntau hom zaub mov, tshuaj, thiab qee cov ntawv thov hauv tsev. Kev siv cov tshuaj yej hnab thiab kas fes lim ntawv ua piv txwv, muab tso ncaj qha rau hauv dej kub yam tsis muaj nag lossis daus ntawm cov yas lossis lwm yam khoom tsis zoo rau tib neeg lub cev.
2. Biodegradability
Siv daim ntawv thov cov hnab tshuaj yej ua piv txwv, ntau lub hnab tshuaj yej pov tseg tau noj thoob ntiaj teb txhua hnub. Tshuaj yej hnab ua los ntawm cov khoom siv ib txwm muaj lub voj voog degradation ntev heev, uas yuav ua rau muaj kev kub ntxhov rau lub ntuj ecology. Txawm li cas los xij, lub hnab tshuaj yej lossis lwm yam khoom tsim los ntawm cov ntaub ntawv polylactic acid muaj biodegradability zoo heev.
Polylactic acid fiber non-woven npuag cov khoom tuaj yeem decomposed rau hauv cov pa roj carbon dioxide thiab dej los ntawm cov kab mob nyob rau hauv ib puag ncig ntuj nrog qee qhov kub thiab av noo, xws li xuab zeb, silt, thiab dej hiav txwv. Polylactic acid cov khoom pov tseg tuaj yeem decomposed tag nrho rau hauv carbon dioxide thiab dej nyob rau hauv industrial composting tej yam kev mob (kub 58 ℃, vaum 98%, thiab microbial tej yam kev mob) rau 3-6 lub hlis; Landfilling nyob rau hauv cov pa ib puag ncig kuj tuaj yeem ua tiav degradation hauv 3-5 xyoos.
3. tuaj yeem tov nrog ntoo pulp lossis lwm yam ntuj fibers rau kev siv
Polylactic acid fibers feem ntau yog sib xyaw rau hauv ib qho kev faib ua feem nrog ntoo pulp fibers, nanofibers, thiab lwm yam. Polylactic acid feem ntau ua lub luag haujlwm hauv kev sib txuas thiab kev txhawb zog, los ntawm kev sib txuas ntawm lwm cov fibers los ntawm kev kub thiab kub kom ua tiav lub hom phiaj ntawm kev sib txuas thiab ntxiv dag zog. Tsis tas li ntawd, los ntawm kev kho cov slurry piv thiab cov txheej txheem ua, nws tuaj yeem ua tau raws li qhov xav tau ntawm cov xwm txheej sib txawv.
4. Ultrasonic thermal bonding tuaj yeem ua tiav
Los ntawm kev siv polylactic acid fibers los ua pulp thiab ntawv, ultrasonic thermal bonding tuaj yeem ua tiav hauv kev tsim khoom tom ntej, uas tsis tsuas yog txuag zog thiab txo cov nqi, tab sis kuj txhim kho kev tsim khoom.
5. Lim kev ua haujlwm
Cov tshuaj yej lim ntawv ua los ntawm polylactic acid fiber ntau muaj kev pom zoo thiab muaj zog ntub dej, uas tuaj yeem khaws cov tshuaj yej nplooj thiab lwm yam khoom, thaum tso cai rau saj thiab aroma ntawm tshuaj yej kom nkag mus rau hauv cov tshuaj yej nplooj.
Ntxiv rau cov tshuaj yej lim ntawv, polylactic acid fiber kuj tuaj yeem siv rau hauv cov tshuaj suav tshuaj ntim cov ntawv lim dej, kas fes lim ntawv, thiab lwm yam ntawv ntim khoom noj.
