Tuam Tshoj yog lub tebchaws uas muaj ntau hom xyoob thiab qib siab tshaj plaws ntawm kev tswj hwm xyoob. Nrog nws cov txiaj ntsig zoo ntawm cov khoom siv xyoob thiab cov thev naus laus zis ua ntawv xyoob uas laus zuj zus, kev lag luam ua ntawv xyoob tab tom vam meej thiab qhov nrawm ntawm kev hloov pauv thiab kev txhim kho tau nrawm dua. Xyoo 2021, kuv lub tebchaws cov khoom tsim tawm xyoob yog 2.42 lab tons, nce ntxiv 10.5% txhua xyoo; muaj 23 lub tuam txhab tsim khoom xyoob ntau dua qhov loj me, nrog 76,000 tus neeg ua haujlwm thiab tus nqi tsim tawm ntawm 13.2 billion yuan; muaj 92 lub tuam txhab ua ntawv xyoob thiab ntawv ua thiab tsim khoom, nrog 35,000 tus neeg ua haujlwm thiab tus nqi tsim tawm ntawm 7.15 billion yuan; muaj ntau dua 80 lub tuam txhab tsim ntawv ua tes siv xyoob ua cov khoom siv raw, nrog kwv yees li 5,000 tus neeg ua haujlwm thiab tus nqi tsim tawm ntawm kwv yees li 700 lab yuan; Qhov kev nrawm ntawm kev tshem tawm cov peev xwm tsim khoom rov qab tau ua kom nrawm dua, thiab cov thev naus laus zis ua noj pulping thiab bleaching siab heev, cov tshuaj lom neeg tshuab pulping ua ntej impregnation thiab pulping thev naus laus zis thiab cov khoom siv tau siv dav hauv kev tsim cov xyoob pulp. kuv lub teb chaws txoj kev lag luam ua ntawv xyoob pulp tab tom txav mus rau kev niaj hnub thiab qhov loj me.
Cov kev ntsuas tshiab
Thaum Lub Kaum Ob Hlis Ntuj xyoo 2021, Lub Chaw Haujlwm Saib Xyuas Hav Zoov thiab Thaj Av, Pawg Neeg Saib Xyuas Kev Txhim Kho thiab Kev Hloov Kho Hauv Tebchaws thiab 10 lub chaw haujlwm tau sib koom ua ke tshaj tawm "Cov Lus Qhia Txog Kev Ua Kom Sai Sai Kev Tsim Kho Tshiab thiab Kev Txhim Kho ntawm Kev Lag Luam Xyoob". Ntau lub zos tau tsim cov cai txhawb nqa los muab kev txhawb nqa txoj cai zoo rau kev txhawb nqa kev txhim kho zoo ntawm kev lag luam xyoob, suav nrog kev lag luam xyoob pulp thiab ntawv. Kuv lub tebchaws cov chaw tsim khoom xyoob pulp thiab ntawv tseem ceeb yog nyob hauv Sichuan, Guizhou, Chongqing, Guangxi, Fujian thiab Yunnan. Ntawm lawv, Sichuan tam sim no yog lub xeev tsim khoom xyoob pulp thiab ntawv loj tshaj plaws hauv kuv lub tebchaws. Nyob rau xyoo tas los no, Sichuan Xeev tau tsim kho kom muaj kev lag luam pulp thiab ntawv sib xyaw ua ke ntawm "xyoob-pulp-ntawv-ua-muag", tsim lub npe ua lag luam xyoob pulp hauv tsev, thiab hloov cov txiaj ntsig ntawm cov peev txheej xyoob ntsuab mus rau hauv kev txhim kho kev lag luam, ua tiav cov txiaj ntsig zoo kawg. Raws li cov peev txheej xyoob nplua nuj, Sichuan tau cog cov ntoo xyoob zoo, txhim kho qhov zoo ntawm cov hauv paus ntoo xyoob, cog cov ntoo xyoob rau ntawm cov roob siab tshaj 25 degrees thiab cov av ua liaj ua teb tsis yog yooj yim nrog cov roob siab ntawm 15 txog 25 degrees hauv cov dej tseem ceeb uas ua tau raws li txoj cai, txhawb nqa kev tswj hwm peb-seem ntawm cov ntoo xyoob, sib koom tes tsim cov ntoo xyoob thiab cov ntoo xyoob ecological, thiab txhawb nqa ntau yam kev them nyiaj thiab kev pab txhawb nqa. Cov chaw khaws cia xyoob tau nce ntxiv tas li. Xyoo 2022, thaj chaw ntoo xyoob hauv lub xeev tau tshaj 18 lab mu, muab ntau cov khoom siv xyoob fiber zoo rau kev ua cov ntoo xyoob pulp thiab ua ntawv, tshwj xeeb tshaj yog cov ntawv hauv tsev xim ntuj xyoob pulp. Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov ntawv hauv tsev xim ntuj xyoob pulp thiab txhim kho kev paub txog hom ntawv hauv tsev xim ntuj hauv tsev thiab txawv teb chaws, Sichuan Paper Industry Association tau thov rau Lub Chaw Haujlwm Trademark ntawm Lub Xeev Intellectual Property Office rau kev sau npe ntawm "Bamboo Pulp Paper" lub npe lag luam ua ke. Txij li yav dhau los kev tawm tsam ib leeg mus rau qhov kev loj hlob tam sim no thiab loj, kev tuav ua ke rau kev sov siab thiab kev koom tes yeej-yeej tau dhau los ua qhov zoo ntawm Sichuan Paper txoj kev loj hlob. Xyoo 2021, muaj 13 lub tuam txhab ua cov ntawv xyoob loj dua qhov loj teev tseg hauv Sichuan Xeev, nrog rau cov khoom tsim tawm ntawm xyoob ntawm 1.2731 lab tons, nce ntxiv txhua xyoo ntawm 7.62%, suav txog 67.13% ntawm lub teb chaws cov khoom tsim tawm ntawm xyoob thawj, uas kwv yees li 80% tau siv los tsim cov ntawv hauv tsev; muaj 58 lub tuam txhab ua ntawv hauv tsev ua ntawv xyoob nrog cov khoom tsim tawm txhua xyoo ntawm 1.256 lab tons; muaj 248 lub tuam txhab ua ntawv hauv tsev ua ntawv xyoob nrog cov khoom tsim tawm txhua xyoo ntawm 1.308 lab tons. 40% ntawm cov ntawv hauv tsev ua los ntawm xyoob ntuj tsim tau muag hauv xeev, thiab 60% muag sab nraum xeev thiab txawv teb chaws los ntawm cov platform muag khoom hauv online thiab lub teb chaws "Belt and Road". Lub ntiaj teb saib rau Tuam Tshoj rau xyoob pulp, thiab Tuam Tshoj saib rau Sichuan rau xyoob pulp. Lub npe Sichuan "bamboo pulp paper" tau mus thoob ntiaj teb.
Cov thev naus laus zis tshiab
Kuv lub teb chaws yog lub ntiaj teb tus tsim cov xyoob pulp / xyoob yaj pulp loj tshaj plaws, nrog 12 cov kab tsim khoom xyoob niaj hnub nrog lub peev xwm tsim khoom txhua xyoo ntawm ntau dua 100,000 tons, tag nrho cov peev xwm tsim khoom ntawm 2.2 lab tons, ntawm cov uas 600,000 tons yog xyoob yaj pulp. Fang Guigan, tus kws tshawb fawb thiab tus thawj coj saib xyuas kev kawm tiav qib siab ntawm Lub Tsev Kawm Ntawv Hav Zoov Khoom Siv Tshuaj ntawm Suav Academy of Forestry, tau cog lus ntev rau kev tshawb fawb thiab kev txhim kho cov thev naus laus zis tseem ceeb thiab cov khoom siv rau kuv lub teb chaws kev lag luam pulping huv siab. Nws hais tias tom qab kev sib koom tes ntawm kev lag luam, kev kawm thiab kev tshawb fawb, cov kws tshawb fawb tau tawg los ntawm cov thev naus laus zis tseem ceeb ntawm xyoob pulp / yaj pulp ntau lawm, thiab cov txheej txheem ua noj thiab tshuaj dawb thiab cov khoom siv tau siv dav hauv kev tsim cov xyoob tshuaj pulp. Los ntawm kev hloov pauv thiab kev siv cov txiaj ntsig tshawb fawb thiab thev naus laus zis xws li "Cov Txuj Ci Tshiab rau Kev Ua Npuas Ncauj Xyoob Zoo thiab Ua Ntawv" txij li "Txoj Kev Npaj Tsib Xyoos Thib Kaum Ob", kuv lub teb chaws tau daws qhov teeb meem ntawm N thiab P ntsev sib npaug hauv cov txheej txheem ntawm kev tshem tawm cov kua qaub dub thiab kev kho cov khoom tawm sab nraud. Tib lub sijhawm, kev vam meej tau ua tiav hauv kev nce qib ntawm qhov dawb ntawm cov khoom ua npuas ncauj siab. Nyob rau hauv qhov xwm txheej ntawm kev siv tshuaj dawb, qhov dawb ntawm cov khoom ua npuas ncauj siab tau nce ntxiv los ntawm tsawg dua 65% mus rau ntau dua 70%. Tam sim no, cov kws tshawb fawb tab tom ua haujlwm los rhuav tshem cov teeb meem kev siv tshuab xws li kev siv hluav taws xob ntau thiab cov txiaj ntsig qis hauv cov txheej txheem tsim cov khoom ua npuas ncauj, thiab siv zog los tsim cov txiaj ntsig zoo hauv kev tsim cov khoom ua npuas ncauj thiab txhim kho kev sib tw thoob ntiaj teb ntawm cov khoom ua npuas ncauj.
Cov cib fim tshiab
Thaum Lub Ib Hlis Ntuj xyoo 2020, tsab cai tshiab txog kev txwv yas hauv tebchaws tau teev tseg qhov ntau thiab tsawg ntawm kev txwv yas thiab kev xaiv lwm txoj hauv kev, coj cov cib fim tshiab rau cov tuam txhab tsim cov ntawv thiab cov khoom siv xyoob. Cov kws tshaj lij tau taw qhia tias nyob rau hauv keeb kwm yav dhau los ntawm "ob chav carbon", xyoob, ua ib qho tseem ceeb ntawm cov hav zoov tsis yog ntoo, ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ruaj ntseg ntoo thoob ntiaj teb, kev txhim kho ntsuab uas tsis muaj carbon, thiab kev txhim kho tib neeg txoj kev ua neej. "Hloov yas nrog xyoob" thiab "hloov ntoo nrog xyoob" muaj peev xwm loj thiab muaj peev xwm loj hlob kev lag luam. Xyoob loj hlob sai, muaj biomass loj thiab nplua nuj nyob rau hauv cov peev txheej. Qhov zoo ntawm xyoob fiber morphology thiab cellulose cov ntsiab lus yog nyob nruab nrab ntawm ntoo coniferous thiab ntoo dav-leaved, thiab xyoob pulp tsim tawm yog sib piv rau ntoo pulp. Cov xyoob pulp fiber ntev dua li ntoo dav-leaved, lub cell phab ntsa microstructure yog tshwj xeeb, lub zog ntaus thiab ductility zoo, thiab cov bleached pulp muaj cov khoom zoo optical. Tib lub sijhawm, xyoob muaj cov ntsiab lus cellulose siab thiab yog cov khoom siv fiber zoo heev rau kev ua ntawv. Cov yam ntxwv sib txawv ntawm cov xyoob pulp thiab ntoo pulp tuaj yeem siv los tsim ntau yam ntawv thiab cov ntawv zoo. Fang Guigan tau hais tias kev txhim kho kev lag luam xyoob pulp thiab ntawv yog qhov tsis sib cais los ntawm kev tsim kho tshiab: thawj zaug, kev tsim kho tshiab txoj cai, nce kev txhawb nqa nyiaj txiag, thiab tsim thiab txhim kho cov khoom siv xws li txoj kev, cableways, thiab slides hauv thaj chaw hav zoov xyoob. Qhov thib ob, kev tsim kho tshiab hauv cov khoom siv txiav, tshwj xeeb tshaj yog kev siv dav dav ntawm cov khoom siv txiav tsis siv neeg thiab ntse, yuav txhim kho kev ua haujlwm ntau thiab txo cov nqi txiav. Qhov thib peb, qauv kev tsim kho tshiab, hauv thaj chaw uas muaj cov peev txheej zoo, npaj thiab tsim cov chaw ua lag luam ua xyoob, nthuav dav cov saw hlau kev lag luam thiab nthuav dav cov saw hlau ua tiav, ua tiav kev siv cov peev txheej xyoob zoo tag nrho, thiab ua kom muaj txiaj ntsig zoo tshaj plaws ntawm kev lag luam xyoob. Qhov thib plaub, kev tshawb fawb thiab thev naus laus zis tshiab, nthuav dav cov hom khoom ua xyoob, xws li cov ntaub ntawv qauv xyoob, cov laug cam xyoob, kev ua tiav tob ntawm nplooj xyoob, kev ua tiav tob ntawm cov chips xyoob (nodes, xyoob daj, xyoob bran), kev siv lignin muaj nqis siab, thiab nthuav dav qhov ntau thiab tsawg ntawm kev siv cellulose (dissolving pulp); daws cov teeb meem tseem ceeb hauv kev tsim cov xyoob pulp hauv txoj kev tsom mus rau thiab paub txog kev niaj hnub ntawm cov thev naus laus zis hauv tsev thiab cov khoom siv.
