Kodi msika wapakhomo ndi wakunja wa non-ionic cellulose ether uli bwanji?

(1)Mwachidule pamsika wapadziko lonse wa nonionic cellulose ether:

Kutengera kugawa kwapadziko lonse lapansi, 43% yapadziko lonse lapansicellulose etherkupanga mu 2018 kunachokera ku Asia (China idawerengera 79% ya Asia), Western Europe idawerengera 36%, ndipo North America idawerengera 8%. Kuchokera pakuwona kufunika kwa cellulose ether padziko lonse lapansi, kugwiritsidwa ntchito kwa cellulose ether padziko lonse lapansi mu 2018 ndi pafupifupi matani 1.1 miliyoni. Kuyambira 2018 mpaka 2023, kumwa kwa cellulose ether kudzakula pamtengo wapachaka wa 2.9%.

Pafupifupi theka la chiwerengero cha padziko lonse lapansi chomwe chimagwiritsidwa ntchito pa cellulose ether ndi ionic cellulose (yoyimiridwa ndi CMC), yomwe imagwiritsidwa ntchito makamaka mu zotsukira, mafuta opangira mafuta ndi zakudya zowonjezera; pafupifupi gawo limodzi mwa magawo atatu aliwonse ndi non-ionic methyl cellulose ndi zotumphukira zake (zoyimiridwa ndiMtengo wa HPMC), ndipo gawo limodzi mwa magawo asanu ndi limodzi otsala ndi hydroxyethyl cellulose ndi zotumphukira zake ndi ma cellulose ethers ena. Kukula kwa kufunikira kwa ma ethers omwe si a ionic cellulose kumayendetsedwa makamaka ndi ntchito pazinthu zomangira, zokutira, chakudya, mankhwala, ndi mankhwala atsiku ndi tsiku. Pakuwona kugawidwa kwamadera kwa msika wa ogula, msika waku Asia ndiye msika womwe ukukula mwachangu. Kuyambira 2014 mpaka 2019, kuchuluka kwapachaka kwa kufunikira kwa cellulose ether ku Asia kudafika 8.24%. Pakati pawo, kufunikira kwakukulu ku Asia kumachokera ku China, kuwerengera 23% ya zomwe zikufunika padziko lonse lapansi.

(2)Chidule cha msika wapakhomo wa non-ionic cellulose ether:

Ku China, ma ionic cellulose ethers amaimiridwa ndiCMCkupangidwa kale, kupanga njira yopangira okhwima komanso mphamvu yayikulu yopanga. Malinga ndi data ya IHS, opanga aku China atenga pafupifupi theka lazomwe amapanga padziko lonse lapansi pazinthu zoyambira za CMC. Kukula kwa non-ionic cellulose ether kudayamba mochedwa m'dziko langa, koma liwiro lachitukuko liri mwachangu.

Malinga ndi deta ya China Cellulose Industry Association, kuchuluka kwa kupanga, kutulutsa ndi kugulitsa ma ethers omwe si a ionic cellulose mabizinesi apakhomo ku China kuyambira 2019 mpaka 2021 ndi motere:

Pambuyo pazaka zachitukuko, msika waku China wopanda ionic cellulose ether wapita patsogolo kwambiri. Mu 2021, mphamvu yopangira zida zomangira HPMC idzafika matani 117,600, zotulutsa zidzakhala matani 104,300, ndipo voliyumu yogulitsa idzakhala matani 97,500. Kukula kwakukulu kwa mafakitale ndi maubwino opezeka m'derali zapangitsa kuti m'malo mwanyumba. Komabe, kwa mankhwala HEC, chifukwa cha mochedwa chiyambi cha R&D ndi kupanga m'dziko langa, ndondomeko zovuta kupanga ndi zotchinga ndi mkulu luso, mphamvu panopa kupanga, kupanga ndi malonda buku la HEC zoweta katundu ndi ochepa. Komabe, m'zaka zaposachedwa, monga mabizinesi apakhomo akupitiliza kukulitsa ndalama pakufufuza ndi chitukuko, kukonza luso laukadaulo ndikukulitsa makasitomala akumunsi, kupanga ndi kugulitsa kwakula mwachangu. Malinga ndi zomwe zachokera ku China Cellulose Viwanda Association, mu 2021, mabizinesi akuluakulu apakhomo HEC (yomwe ikuphatikizidwa ndi ziwerengero zamabizinesi, zolinga zonse) ali ndi kuthekera kopanga kopanga matani 19,000, kutulutsa matani 17,300, ndikugulitsa matani 16,800. Pakati pawo, mphamvu zopanga zidakwera ndi 72,73% pachaka poyerekeza ndi 2020, zotulutsa zidakwera ndi 43.41% pachaka, ndipo kuchuluka kwa malonda kumawonjezeka ndi 40,60% pachaka.

Monga chowonjezera, kuchuluka kwa malonda a HEC kumakhudzidwa kwambiri ndi kufunikira kwa msika wapansi. Monga gawo lofunikira kwambiri la HEC, makampani opanga zokutira ali ndi mgwirizano wamphamvu ndi makampani a HEC potengera kutulutsa ndi kugawa msika. Potengera kugawa msika, msika wamakampani opanga zokutira umagawidwa makamaka ku Jiangsu, Zhejiang ndi Shanghai ku East China, Guangdong ku South China, gombe lakumwera chakum'mawa, ndi Sichuan kumwera chakumadzulo kwa China. Pakati pawo, ❖ kuyanika linanena bungwe Jiangsu, Zhejiang, Shanghai ndi Fujian anali pafupifupi 32%, ndipo ku South China ndi Guangdong anali pafupifupi 20%. 5 pamwamba. Msika wazinthu za HEC umakhazikikanso ku Jiangsu, Zhejiang, Shanghai, Guangdong ndi Fujian. HEC pakali pano imagwiritsidwa ntchito makamaka pazovala zomanga, koma ndiyoyenera mitundu yonse ya zokutira zokhala ndi madzi potengera zomwe zimapangidwa.

Mu 2021, chiwopsezo chapachaka cha zokutira zaku China chikuyembekezeka kukhala matani pafupifupi 25.82 miliyoni, ndipo zopangira zopangira zomangamanga ndi zokutira zamafakitale zidzakhala matani 7.51 miliyoni ndi matani 18.31 miliyoni motsatana. Zopaka zokhala ndi madzi pakali pano zimapanga pafupifupi 90% ya zokutira zomanga, ndipo pafupifupi 25%, akuti kupanga utoto wopangidwa ndi madzi mdziko langa mu 2021 kudzakhala pafupifupi matani 11.3365 miliyoni. Mwachidziwitso, kuchuluka kwa HEC yowonjezeredwa ku utoto wopangidwa ndi madzi ndi 0.1% mpaka 0.5%, yowerengedwa pa avareji ya 0.3%, poganiza kuti utoto wonse wamadzi umagwiritsa ntchito HEC monga chowonjezera, kufunikira kwa dziko lonse kwa kalasi ya penti ya HEC ndi pafupifupi matani 34,000. Kutengera kuchuluka kwa zokutira zapadziko lonse lapansi za matani 97.6 miliyoni mu 2020 (omwe zokutira zomanga zimatengera 58.20% ndi zokutira zamafakitale ndi 41.80%), kufunikira kwapadziko lonse kwa kalasi ya HEC kukuyerekeza kukhala pafupifupi matani 184,000.

Pomaliza, pakali pano, gawo la msika wa ❖ kuyanika kalasi HEC opanga zoweta ku China akadali otsika, ndipo gawo msika zoweta makamaka wotanganidwa ndi opanga mayiko akuimiridwa ndi Ashland wa United States, ndipo pali malo lalikulu m'malo zoweta. Ndi kusintha kwa zinthu zapakhomo za HEC komanso kukulitsa mphamvu zopangira, idzapikisananso ndi opanga mayiko omwe ali pansi pamtsinje woimiridwa ndi zokutira. Kulowa m'malo mwapakhomo komanso mpikisano wamsika wapadziko lonse lapansi udzakhala njira yayikulu yopititsira patsogolo makampaniwa munthawi ina mtsogolo.

MHEC imagwiritsidwa ntchito kwambiri pantchito yomanga. Nthawi zambiri amagwiritsidwa ntchito mumatope a simenti kuti apititse patsogolo kusungirako madzi, kutalikitsa nthawi yoyika matope a simenti, kuchepetsa mphamvu yake yosinthasintha ndi mphamvu zopondereza, ndikuwonjezera mphamvu zake zomangirira. Chifukwa cha gel osakaniza a mtundu uwu wa mankhwala, sagwiritsidwa ntchito pang'onopang'ono m'munda wa zokutira, ndipo makamaka amapikisana ndi HPMC m'munda wa zipangizo zomangira. MHEC ili ndi malo a gel, koma ndi apamwamba kuposa HPMC, ndipo pamene zomwe zili mu hydroxy ethoxy zikuwonjezeka, gel ake amapita kumalo otentha kwambiri. Ngati imagwiritsidwa ntchito mumatope osakanikirana, ndizothandiza kuchedwetsa slurry ya simenti pa kutentha kwakukulu kwa Bulk electrochemical reaction, kuonjezera kuchuluka kwa kusungirako madzi ndi kulimba kwa mgwirizano wa slurry ndi zotsatira zina.

Kukula kwa ndalama zogwirira ntchito yomanga, malo omanga nyumba, malo omalizidwa, malo okongoletsera nyumba, malo okonzanso nyumba zakale ndi kusintha kwawo ndizinthu zazikulu zomwe zimakhudza kufunika kwa MHEC pamsika wapakhomo. Kuyambira 2021, chifukwa cha vuto la mliri wa chibayo chatsopano, malamulo oyendetsera nyumba, komanso kuwopsa kwamakampani ogulitsa nyumba, kutukuka kwamakampani aku China kwatsika, koma makampani ogulitsa nyumba akadali bizinesi yofunika kwambiri pakukula kwachuma ku China. Pansi pa mfundo zonse za "kuponderezedwa", "kuletsa zofuna zopanda nzeru", "kukhazikika kwa mitengo ya nthaka, kukhazikika kwa mitengo ya nyumba, ndi kukhazikika kwa ziyembekezo", ikugogomezera kuyang'ana pa kusintha kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake Njira yoyendetsera bwino yowonetsetsa kuti msika wanyumba ndi nyumba zikuyenda bwino, zokhazikika komanso zathanzi. M'tsogolomu, chitukuko cha malonda ogulitsa nyumba chidzakhala chitukuko chapamwamba kwambiri ndi khalidwe lapamwamba komanso liwiro lotsika. Choncho, kuchepa kwaposachedwa kwa chitukuko cha malonda ogulitsa nyumba kumayambitsidwa ndi kusintha kwapang'onopang'ono kwa makampaniwa polowa m'ndondomeko yachitukuko cha thanzi, ndipo malonda ogulitsa nyumba akadali ndi mwayi wopita patsogolo. Panthawi imodzimodziyo, malinga ndi "Pulogalamu ya 14 ya Zaka zisanu za National Economic and Social Development ndi 2035 Long-term Goal Outline", ikufuna kusintha njira yachitukuko cha mizinda, kuphatikizapo kufulumizitsa kukonzanso mizinda, kusintha ndi kupititsa patsogolo midzi yakale, mafakitale akale, akale. Kuwonjezeka kwa kufunikira kwa zida zomangira pakukonzanso nyumba zakale ndi njira yofunikira pakukulitsa msika wa MHEC mtsogolomo.

Malinga ndi ziwerengero za China Cellulose Viwanda Association, kuyambira 2019 mpaka 2021, kutulutsa kwa MHEC ndi mabizinesi apakhomo kunali matani 34,652, matani 34,150 ndi matani 20,194 motsatana, ndipo kuchuluka kwa malonda kunali matani 32,531, 33,1200 mpaka 33,5200 kutsika, mayendedwe. Chifukwa chachikulu ndi chimenechoMHECndi HPMC ntchito zofanana, ndipo makamaka ntchito zomangira monga matope. Komabe, mtengo ndi kugulitsa mtengo wa MHEC ndi wapamwamba kuposa waMtengo wa HPMC. Pankhani yakukula kosalekeza kwa HPMC yopanga zapakhomo, kufunikira kwa msika wa MHEC kwatsika. Mu 2019 Pofika 2021, kuyerekeza pakati pa MHEC ndi HPMC kutulutsa, kuchuluka kwa malonda, mtengo wapakati, ndi zina zotere ndi motere:
