Xyoob dhau los ua lub tsev khoom muaj nqis ntawm cov khoom siv tshiab
Nrog thaj tsam ntawm 7.01 lab hectares ntawm xyoob hav zoov, Tuam Tshoj yog lub teb chaws uas muaj cov khoom siv xyoob ntau tshaj plaws hauv ntiaj teb. Cov peev txheej xyoob, thaj chaw thiab cov khoom lag luam yog thawj zaug hauv ntiaj teb. Txog tam sim no, muaj 857 hom xyoob nroj tsuag uas muaj 39 genera hauv Suav teb, suav txog 52 feem pua ntawm 1642 hom xyoob hauv ntiaj teb.
Xyoob muaj qhov zoo ntawm kev rov ua dua tshiab, nqus cov pa roj carbon dioxide, cov khoom tsis muaj kuab lom thiab degradable, thiab muaj ntau yam kev siv. Nws tuaj yeem paub txog kev siv txhua xyoob ntoo, yuav luag tsis muaj pov tseg. Los ntawm cov khoom siv xws li riam, diav rawg, diav, khob thiab daim hlau mus rau cov khoom siv hauv tsev niaj hnub, tsheb sab hauv, cov khoom siv hluav taws xob, thiab txawm tias xyoob lattice fillers rau cov cua txias hauv kev lag luam, cov khoom xyoob tau maj mam nkag mus rau tib neeg lub neej.
Txhim kho kev siv cov khoom siv xyoob los ntawm kev tshawb fawb thiab thev naus laus zis, thiab maj mam txhim kho thiab siv xyoob los hloov cov ntoo, yas, hlau thiab lwm yam ntaub ntawv, tsim ntau tshaj 100 series thiab ntau tshaj 10000 ntau yam ntawm xyoob reconstituted, xyoob woven handicrafts, xyoob. cov khoom siv fiber ntau, cov khoom siv xyoob carbon, thiab lwm yam, thiab cov khoom ua tiav xyoob tau npog tag nrho cov teb ntawm tib neeg cov khoom thiab lub neej. Tuam Tshoj yog lub teb chaws loj tshaj plaws hauv kev tsim khoom thiab kev lag luam ntawm cov khoom xyoob hauv ntiaj teb. Xyoo 2020, tus nqi tsim tawm ntawm lub teb chaws xyoob kev lag luam yuav ze li ntawm 320 billion yuan.
Nrog rau kev xav tau ntau ntxiv rau kev kho kom zoo nkauj ntawm ib puag ncig hauv tsev, muaj ntau thiab ntau kev tshawb fawb txog kev hloov cov ntaub ntawv tiv thaiv ib puag ncig xws li ntoo thiab xyoob rau hauv cov ntaub ntawv tshiab, tab sis ob peb ntawm lawv ncaj qha ua cov xyoob nyoos rau hauv cellulose composites nrog cov khoom siv kho qhov muag zoo.
Vim yog qhov tsis tshua muaj porosity ntawm xyoob, lub sij hawm tshem tawm lignin thiab impregnating polymer los ntawm xyoob yog ntev dua li cov ntoo uas tsis tshua muaj ntom xws li Basha ntoo thiab poplar, yog li nws yog ib qho nyuaj rau npaj pob tshab xyoob nrog tej thickness.
Pab pawg tau xaiv 5- xyoo-laus phyllostachys pubescens ua cov khoom siv raw, soaked xyoob ntsuab nyob rau hauv cov tov tov ntawm hydrogen peroxide thiab acetic acid, thiab reacted lignin nrog peracetic acid los tsim trans-dihydroxylation ntxiv cov khoom; Tom qab ntawd siv cov tshuaj pretreatment yooj yim tshem tawm cov lignin hauv cov xyoob qub. Nws qhov kev tshem tawm txhais tau tias ploj ntawm "nplaum" (txuas cellulose thiab hemicellulose), ua rau cov tsos ntawm cov pores ntau dua, uas yog qhov zoo rau kev sau cov resin nrog refractive Performance index txuam nrog xyoob cellulose template.
Thaum kawg, tom qab kev kho sai sai, cov khoom siv xyoob pob tshab tshiab nrog kev ua haujlwm zoo tshaj plaws ntawm kev sib kis, tensile tsis kam, nto kho kom zoo nkauj thiab tus nqi zoo nkauj tau los ua.
Piv nrog rau lwm cov qauv pob tshab biomass npaj los ntawm cov txheej txheem polymer impregnation sib txawv, lub sijhawm kho ntawm pob tshab pob tshab yog luv heev, yog li nws qhia tau hais tias muaj peev xwm tseem ceeb rau kev npaj sai thiab ua tiav.
Pob tshab xyoob hloov electromagnetic shielding khoom
Nrog rau txoj kev loj hlob sai ntawm kev sib txuas lus wireless thiab cov khoom siv hluav taws xob, kev yooj yim ntawm tib neeg lub neej tau nce, tab sis cov teeb meem ntawm electromagnetic cuam tshuam, hluav taws xob thiab hluav taws xob hluav taws xob tau nce ntxiv. Ib puag ncig electromagnetic deteriorating tsis tsuas yog ua rau tib neeg txoj kev noj qab haus huv, tab sis kuj cuam tshuam nrog kev ua haujlwm ntawm ntau yam khoom siv hluav taws xob.
Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau kawm cov ntaub ntawv tiv thaiv electromagnetic rau cov tsev thiab cov tsev.
Xib fwb Wu Yan tau hais tias kev ua haujlwm ncaj qha ntawm cov xyoob nyoos rau hauv cov khoom siv cellulose tsis tsuas yog txo cov kev siv zog ntau hauv cov txheej txheem ua ntej, tab sis kuj tseem khaws cov txheej txheem cellulose skeleton ua tiav ntawm cov xyoob nyoos. Hauv txoj kev tshawb no, lawv ncaj qha tsim thiab ua tiav xyoob nyoos hauv nws tus kheej daim ntawv, uas tsis tsuas yog nthuav dav siv biomass optical pob tshab cov ntaub ntawv, tab sis kuj tau ua ntau hom kev ua qauv.
Nws tau tshaj tawm tias cov phab ntsa tuab ntawm cov khoom siv pob tshab tshiab tuaj yeem ncav cuag 6.23 hli, lub teeb xa tawm yog li 60 feem pua, lub teeb pom kev zoo yog 1000 lux, cov dej nqus huab cua hloov pauv tsawg dua 4 feem pua, qhov ntev tensile lub zog ncav cuag 46.40. MPa, thiab qhov kev ua haujlwm saum npoo yog 80.2HD (lub hardness unit ntsuas los ntawm Brinell hardness tester).
Cov neeg koom tes tsim cov cuab yeej sib xyaw ntawm cov pob tshab pob tshab, pob tshab xyoob chips thiab electromagnetic shielding zaj duab xis. "Cov qauv tag nrho zoo ib yam li lub rooj sib tham honeycomb," Wu Yan tau hais. Ntawm lawv, pob tshab xyoob chips ua cov pob txha pob txha, pob tshab xyoob chips ua vaj huam sib luag, thiab tin-doped indium oxide zaj duab xis ua cov txheej txheem ua haujlwm.
Tom qab kev tshawb fawb, Wu Yan pab neeg tau pom tias cov cuab yeej sib xyaw no tuaj yeem ua kom pom cov rwb thaiv tsev kub, thermal rwb thaiv tsev thiab electromagnetic shielding kev ua tau zoo, thiab muaj kev cia siab dav hauv cov khoom siv kho kom zoo nkauj hauv tsev thiab lub tsev.
"Qhov no txoj kev ncaj qha ua raw xyoob rau hauv cellulose templates thiab tom qab ntawd synthesizing pob tshab cov ntaub ntawv yuav txo tau cov kauj ruam ntawm mechanical processing raw cov ntaub ntawv nyob rau hauv thaum ntxov thiab molding ntawm raw cov ntaub ntawv nyob rau hauv lub tom ntej theem, tsis tsuas yog txo lub zog noj, tab sis kuj txo. kev pov tseg ntawm cov peev txheej petrochemical, "Wu Yan tau hais. Nyob rau tib lub sijhawm, txoj kev no tseem tuaj yeem txuas ntxiv mus rau lwm cov khoom siv biomass uas muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom tshuab tuaj yeem txuas ntxiv mus rau lwm cov khoom siv biomass.
