1)Daim ntawv thov tseem ceeb ntawm lub tsev cov khoom siv qib cellulose ether
Daim teb ntawm cov ntaub ntawv tsim tsev yog cov teb tseem ceeb ntawmCellulose etherCov. Cellulose ether muaj cov khoom zoo heev xws li xaim xaim hluav taws xob, ua kom nrawm nrawm nrawm nrawm dua) Cov khoom lag luam nplais, kev ua haujlwm khoom siv suav nrog cov khoom siv hluav taws xob thiab kev tsim kho kom zoo nkauj, thiab yog kev tsim kho kom ncaj qha rau cov yasonry thiab sab nrauv phab ntsa Kho kom zoo nkauj ntawm ntau hom kev tsim kho cov haujlwm. Vim tias cov peev txheej loj ntawm kev nqis peev hauv kev tsim kho cov engineering, ntau hom kev tsim kho tau tawg ntau heev, muaj ntau hom kev ua haujlwm ntawm cov yam ntxwv ntawm kev siv dav ntau yam, kev lag luam loj , thiab cov neeg siv khoom tawg.
Ntawm cov qauv nruab nrab thiab qib siab kawg ntawm tsev cov khoom kawm qib HPMC, lub tsev khoom siv qib HPMC nrog lub qhov kub thiab txias ntawm ultrasonic cug thiab lwm daim teb. Nws muaj cov kub siab tiv thaiv thiab cov ntawv thov zoo nyhuv. Nws daim ntawv thov kev ua tau zoo yog qhov chaw kub thiab txias nws tsis tuaj yeem hloov los ntawm lub tsev cov khoom qib HPMC ntawm 60 ° C, thiab High-° siab yuav tsum muaj qhov zoo dua ntawm cov khoom lag luam zoo ntawm hom khoom no. Nyob rau tib lub sijhawm, nws yog qhov kev nyuaj nyuaj los tsim HPMC nrog qhov kub ntawm 75 ° C. Cov peev txheej ntawm cov khoom siv tsim khoom loj heev, thiab nkag mus hauv chaw nkag yog qhov siab. Tus nqi ntawm cov khoom yog qhov siab dua li ntawd ntawm lub tsev cov khoom kawm qib HPMC nrog qhov kub ntawm 60 ° C.
Lub siab-kawg PVC-SPAGE HPMC yog qhov tseem ceeb ntxiv rau cov khoom siv ntawm PVC. Txawm hais tias HPMC ntxiv rau hauv cov nyiaj thiab cov nqi tsawg ntawm PVC cov nqi thov kev ua tau zoo, yog li nws cov kev xav tau yog qhov siab. Muaj ob peb cov neeg ua lag luam txawv teb chaws ntawm HPMC rau PVC, thiab tus nqi ntawm cov khoom lag luam txawv teb yog ntau dua li cov khoom lag luam hauv tsev.
2)Kev txhim kho txoj kev loj hlob ntawm lub tsev cov khoom siv qib cellulose kev lag luam ether
①Kev tsim kho ntawm kuv lub teb chaws txoj kev tsim kho txuas ntxiv mus tsav lub lag luam xav tau lub tsev cov khoom siv txheeb cais Ether
Raws li cov ntaub ntawv tso tawm los ntawm National Coreau ntawm cov neeg txheeb cais, hauv 2021, kuv lub teb chaws hauv nroog) yuav ncav cuag 64.72 feem pua cov ntsiab lus piv nrog 2020, thiab Qhov nce ntxiv piv nrog Urbanization tus nqi ntawm 49.95% xyoo 2010. 14.77 feem pua hauv xyoo 2010. Qhia tias kuv lub teb chaws tau nkag mus rau hauv nruab nrab thiab lig theem ntawm cov nroog hauv nroog. Sib xyaws, txoj kev loj hlob ntawm tag nrho cov kev thov hauv kev ua lag luam qub tsev kuj tseem nkag mus rau theem sib txawv, thiab sib txawv ntawm kev xav tau hauv cov nroog sib txawv tau dhau los ua qhov pom tseeb. Qhov kev thov kom muaj vaj tse nyob ntxiv. Yav tom ntej, nrog kev poob qis ntawm kuv lub teb chaws tsim kev lag luam thiab kev nce siab ntawm cov kev pabcuam ua haujlwm, thiab kev tsim kho cov qauv hauv chav ua haujlwm, cov kev xav tau tshiab yuav yog Muab tso rau pem hauv ntej rau hauv nroog lag luam, chaw nyob thiab chaw nyob sib npaug. Cov khoom lag luam muag khoom cov kev xav tau ntawm kev lag luam yuav muaj ntau yam kev lag luam, thiab kev lag luam kev tsim kho vaj tse tau nkag mus rau lub sijhawm hloov pauv thiab hloov pauv.
Kev lag luam teev ntawm kev tsim kho kev tsim kho, thaj chaw tsim kho, thaj chaw ua tiav, yog qhov tseem ceeb ntawm cov neeg nyob hauv tsev ua lag luam rau kev ua lag luam hauv tsev Cov khoom siv tau qhab nia ntawm Cellulose ether. Cov txheej txheem ntawm cov txheej txheem yog ze rau. Txij xyoo 2010 txog 2021, Kuv lub teb chaws cov peev txheej vaj tse ua tiav thiab tsim cov txiaj ntsig tawm ntawm kev tsim kho cov txiaj ntsig yeej tswj hwm kev loj hlob sib luag. Xyoo 2021, kuv lub teb chaws yog Vaj Tse Vaj Tse Kev Tsim Kho Cov Nqi yog 14.76 trillion yuan, ib xyoo-nyob rau xyoo nce ntawm 4.35%; Kev tsim kho kev lag luam Tag nrho cov zis cov txiaj ntsig yog 29.31 Treillion Yuan, nce 11.04% thawm xyoo.
Los ntawm 2011 txog 2021, qhov nruab nrab txhua xyoo compound kev loj hlob ntawm vaj tse kev tsim kho vaj tse nyob hauv kuv lub teb chaws txoj kev tsim kho ntawm kev tsim kho ntawm vaj tsev yog 0.91%. Xyoo 2021, thaj chaw tsim kho vaj tse ntawm kuv lub teb chaws txoj kev tsim kho yuav yog 9.754 billion square metres, nrog ib xyoos-xyoo-xyoo; Lub chaw tsim kev kawm ua tiav yuav yog 1.014 billion square metres, nrog ib xyoos-nyob rau ib xyoos kev loj hlob tus nqi ntawm 11.20%. Txoj kev loj hlob zoo ntawm kev tsim kho kev tsim kho hauv tsev yuav ua rau kev siv cug cov khoom lag luam xws li npaj ua khoom lag luam, thiab cov xim yas, thiab cov xim yas, thiab cov xim yas, thiab cov xim yas, thiab cov khoom lag luam yas, thiab cov khoom lag luam yas, thiab cov khoom lag luam yas cellulose ether.
②Lub teb chaws nquag txhawb nqa cov khoom siv ntsuab tom ntsuab sawv cev los ntawm npaj hom khoom siv cov khoom lag luam ether ether yog txuas ntxiv ntxiv
Tshuaj khib nyiab yog ib qho khoom sib xyaw ua ke hauv kev tsim cov cib. Nws yog tsim ntawm qee qhov kev faib ua feem ntawm cov xuab zeb thiab cov khoom lag luam hauv tsev (Maas, Qime Muab Tshuaj Txhuam, av nplaum, thiab lwm yam) thiab dej. Kev coj ua ntawm kev siv tshuaj cug yog nyob rau ntawm kev tsim kho cov kev tsim kho thiab kev txhim kho ntawm cov kev tsim kho, xws li tsis muaj zoo, loj pov tseg ntawm Cov ntaub ntawv, ib hom tshuaj khib, tsawg degree ntawm kev tsim kho kom meej thiab ua kom ib puag ncig, thiab lwm yam.
Piv nrog on-site tov cug, cov txheej txheem npaj txhij-sib xyaw ua ke, thiab cov txheej txheem txau ntawm ntub sib xyaw nws tus kheej, uas tau txo ntau tiam neeg ntawm hmoov av thiab yog yooj yim rau kev tsim kho mechanized. Yog li ntawd npaj-mixed-mixed-mixed-zoo hom, muaj zog ntau yam, txuag hluav taws xob, thiab muaj kev pab nyiaj txiag zoo thiab ib puag ncig. Txij li xyoo 2003, lub xeev tau tshaj tawm cov ntaub ntawv tseem ceeb ntawm txoj cai los txhawb nqa cov tshuaj khib thiab ua tiav npaj kom npaj txhij cov qauv cug kev lag luam.
Tam sim no, kev siv ntawm kev npaj txhij-mixed-mixed-mixed-mixed-ensed cug vem tau dhau los ua ib qho tseem ceeb ntawm PM2.5 emissions hauv kev tsim kho kev tsim kho. Nyob rau yav tom ntej, nrog kev nce nqi ntawm cov xuab zeb thiab gravel cov nqi, tus nqi ncaj qha siv cov xuab zeb nce ntxiv, thiab nce ncaj qha rau kev siv cov nqi ntawm cov nqi ntawm cov tshuaj sib nphoo, Thiab qhov kev thov tau npaj txhij-sib xyaw ua ke hauv kev tsim kho kev tsim kho yuav txuas ntxiv mus ntxiv. Tus nqi ntawm lub tsev cov khoom siv qib cellulose ether hauv kev txhaj tshuaj khib nyiab feem ntau suav nrog kwv yees li 2 / 10,000. Ntxiv cov cellulose ether pab ua kom tuab cov tshuaj khib, khaws dej thiab txhim kho kev ua haujlwm. Qhov nce kuj tseem yuav tsav txoj kev loj hlob ntawm kev thov kom lub tsev cov khoom siv Cellulose ether.
