Sinjani isimo semakethe yasekhaya nengaphandle ye-non-ionic cellulose ether?

(1)Ukubuka konke kwemakethe yomhlaba wonke ye-nonionic cellulose ether:

Ngokombono wokusatshalaliswa kwamandla okukhiqiza emhlabeni wonke, ama-43% engqikithi yomhlaba wonkei-cellulose etherukukhiqizwa ngo-2018 kwavela e-Asia (i-China yabalelwa ku-79% wokukhiqiza wase-Asia), iNtshonalanga Yurophu yaba ngama-36%, kanti iNyakatho Melika yaba ngu-8%. Ngokombono wesidingo se-cellulose ether emhlabeni wonke, ukusetshenziswa kwe-cellulose ether emhlabeni wonke ngo-2018 cishe kungamathani ayizigidi ezingu-1.1. Kusukela ngo-2018 kuya ku-2023, ukusetshenziswa kwe-cellulose ether kuzokhula ngesilinganiso sonyaka se-2.9%.

Cishe ingxenye yengqikithi yokusetshenziswa kwe-cellulose ether yomhlaba wonke i-ionic cellulose (emelwe yi-CMC), esetshenziswa kakhulu ezintweni zokuhlanza, izithasiselo zasezindaweni zikawoyela nezithasiselo zokudla; cishe ingxenye eyodwa kwezintathu i-non-ionic methyl cellulose kanye nezinto eziphuma kuyo (emelweI-HPMC), futhi ingxenye eyodwa kwesithupha esele i-hydroxyethyl cellulose kanye nokuphuma kwayo kanye namanye ama-cellulose ethers. Ukukhula kwesidingo sama-non-ionic cellulose ethers kuqhutshwa ikakhulukazi ukusetshenziswa emkhakheni wezinto zokwakha, okokuhlanganisa, ukudla, imithi, namakhemikhali ansuku zonke. Ngokombono wokusatshalaliswa kwesifunda kwemakethe yabathengi, imakethe yase-Asia iyimakethe ekhula ngokushesha kakhulu. Kusukela ngo-2014 kuya ku-2019, izinga lokukhula elihlanganisiwe lonyaka lesidingo se-cellulose ether e-Asia lifinyelele ku-8.24%. Phakathi kwazo, isidingo esikhulu e-Asia sivela eChina, esibalelwa ku-23% wesidingo somhlaba wonke.

(2)Uhlolojikelele lwemakethe yasekhaya engeyona ionic cellulose ether:

E-China, ama-ether e-ionic cellulose amelwe nguI-CMCithuthukiswe ngaphambilini, yakha inqubo yokukhiqiza eseyivuthiwe kanye namandla amakhulu okukhiqiza. Ngokusho kwedatha ye-IHS, abakhiqizi baseShayina bathathe cishe ingxenye yomthamo wokukhiqiza wemikhiqizo eyisisekelo ye-CMC emhlabeni jikelele. Ukuthuthukiswa kwe-non-ionic cellulose ether kuqale sekwephuzile kakhulu ezweni lami, kodwa isivinini sokuthuthuka siyashesha.

Ngokwemininingwane ye-China Cellulose Industry Association, amandla okukhiqiza, okukhiphayo kanye nokuthengiswa kwama-non-ionic cellulose ethers amabhizinisi asekhaya e-China kusuka ngo-2019 kuya ku-2021 ami kanje:

Ngemva kweminyaka yokuthuthuka, imakethe yaseShayina engeyona ionic cellulose ether yenze inqubekelaphambili enkulu. Ngo-2021, umthamo oklanyelwe wokukhiqiza we-HPMC webanga lezinto zokwakha uzofinyelela amathani ayi-117,600, okuphumayo kuzoba amathani ayi-104,300, kanti umthamo wokuthengisa uzoba amathani angama-97,500. Izinga elikhulu lezimboni kanye nezinzuzo zasendaweni ngokuyisisekelo ziye zabonakala esikhundleni sasekhaya. Kodwa-ke, emikhiqizweni ye-HEC, ngenxa yokuphela kwesikhathi kwe-R&D nokukhiqizwa ezweni lami, inqubo yokukhiqiza eyinkimbinkimbi kanye nezithiyo zobuchwepheshe eziphakeme kakhulu, umthamo wamanje wokukhiqiza, ukukhiqizwa kanye nomthamo wokuthengisa wemikhiqizo yasekhaya ye-HEC mancane kakhulu. Kodwa-ke, eminyakeni yamuva nje, njengoba amabhizinisi asekhaya eqhubeka nokwandisa ukutshalwa kwezimali ocwaningweni nasekuthuthukisweni, athuthukise izinga lobuchwepheshe futhi athuthukise ngenkuthalo amakhasimende awela phansi, ukukhiqizwa nokuthengisa kuye kwanda ngokushesha. Ngokusho kwedatha evela ku-China Cellulose Industry Association, ngo-2021, amabhizinisi amakhulu asekhaya i-HEC (okufakwe nezibalo zenhlangano yezimboni, yonke inhloso) anekhono lokukhiqiza eliklanyelwe amathani ayi-19,000, ukukhishwa kwamathani ayi-17,300, kanye nevolumu yokuthengisa engamathani ayi-16,800. Phakathi kwazo, umthamo wokukhiqiza ukhuphuke ngo-72.73% unyaka nonyaka uma kuqhathaniswa no-2020, okukhiphayo kukhuphuke ngo-43.41% unyaka nonyaka, futhi umthamo wokuthengisa ukhuphuke ngo-40.60% unyaka nonyaka.

Njengesengezo, ivolumu yokuthengisa ye-HEC ithintwa kakhulu isidingo semakethe esiphansi. Njengenkambu yesicelo ebaluleke kakhulu ye-HEC, imboni yokumboza inokuxhumana okuhle okuqinile nemboni ye-HEC mayelana nokuphumayo nokusatshalaliswa kwemakethe. Ngokombono wokusatshalaliswa kwemakethe, imakethe yezimboni zokumboza isatshalaliswa ikakhulukazi eJiangsu, eZhejiang naseShanghai eMpumalanga China, eGuangdong eNingizimu neChina, ogwini oluseningizimu-mpumalanga, naseSichuan eNingizimu-ntshonalanga yeChina. Phakathi kwazo, ukukhishwa kwe-coating e-Jiangsu, e-Zhejiang, e-Shanghai nase-Fujian kulinganiselwa ku-32%, nokuthi eNingizimu ye-China nase-Guangdong kubalwe cishe ama-20%. 5 ngenhla. Imakethe yemikhiqizo ye-HEC igxile kakhulu eJiangsu, Zhejiang, Shanghai, Guangdong naseFujian. I-HEC okwamanje isetshenziswa ngokuyinhloko ekugqokeni kwezakhiwo, kodwa ifanele zonke izinhlobo zezingubo ezisekelwe emanzini ngokwezimfanelo zayo zomkhiqizo.

Ngo-2021, inani eliphelele lokukhishwa kwezingubo zaseChina kulindeleke ukuthi libe amathani ayizigidi ezingama-25.82, kanti ukukhishwa kwezingubo zezakhiwo nezingubo zezimboni kuzoba amathani ayizigidi eziyi-7.51 kanye namathani ayizigidi eziyi-18.31 ngokulandelana6. Izigqoko ezisekelwe emanzini njengamanje zenza cishe amaphesenti angama-90 ezinto zokwakha, futhi cishe zibalelwa ku-25%, kulinganiselwa ukuthi ukukhiqizwa kopende osuselwa emanzini wezwe lami ngo-2021 kuzoba cishe amathani ayizigidi eziyi-11.3365. Ngokwethiyori, inani le-HEC elengezwe kupende osuselwe emanzini lingu-0.1% kuya ku-0.5%, libalwa ngokwesilinganiso esingu-0.3%, kucatshangwa ukuthi bonke opende abasekelwe emanzini basebenzisa i-HEC njengesithasiselo, isidingo sikazwelonke se-HEC yezinga likapende singamathani angama-34,000. Ngokusekelwe engqikithini yokukhiqizwa kokumboza komhlaba wonke okungamathani ayizigidi ezingama-97.6 ngo-2020 (okuhlanganisa ama-architectural coatings afinyelela ku-58.20% futhi okokunamathela ezimbonini kubalelwa ku-41.80%), isidingo somhlaba wonke sokumboza ibanga le-HEC silinganiselwa kumathani ayi-184,000.

Ukufingqa, okwamanje, isabelo semakethe sebanga le-HEC lokumboza labakhiqizi basekhaya e-China sisaphansi, futhi isabelo semakethe yasekhaya sithathwa ikakhulukazi abakhiqizi bamazwe ngamazwe abamelwe yi-Ashland yase-United States, futhi kunesikhala esikhulu sokushintshwa kwasekhaya. Ngokuthuthukiswa kwekhwalithi yomkhiqizo wasekhaya we-HEC kanye nokwanda kwamandla okukhiqiza, izophinde iqhudelane nabakhiqizi bamazwe ngamazwe emkhakheni ongezansi omelwe ama-coatings. Ukushintshwa kwasekhaya kanye nokuncintisana kwezimakethe zamazwe ngamazwe kuzoba inkambiso enkulu yokuthuthukiswa kwale mboni esikhathini esithile esizayo.

I-MHEC isetshenziswa kakhulu emkhakheni wezinto zokwakha. Ivamise ukusetshenziswa odakeni lukasimende ukuze kuthuthukiswe ukugcinwa kwayo kwamanzi, kwelule isikhathi sokumisa sikasimende, kunciphise amandla ayo aguquguqukayo namandla acindezelayo, futhi kwandise amandla ayo okubopha okuqinile. Ngenxa yephuzu lejeli lalolu hlobo lomkhiqizo, lisetshenziswa kancane emkhakheni wezingubo, futhi ikakhulukazi lincintisana ne-HPMC emkhakheni wezinto zokwakha. I-MHEC inephuzu lejeli, kodwa iphakeme kune-HPMC, futhi njengoba okuqukethwe kwe-hydroxy ethoxy kwanda, iphuzu layo lejeli liya lapho lihamba khona izinga lokushisa eliphezulu. Uma isetshenziswa odakeni oluxubile, kuyazuzisa ukubambezeleka kukasimende ezingeni lokushisa eliphezulu Ukusabela kwe-Bulk electrochemical, kukhuphule izinga lokugcinwa kwamanzi namandla ebhondi eqinile ye-slurry neminye imiphumela.

Isilinganiso sokutshalwa kwezimali kwemboni yezokwakha, indawo yokwakha izindlu, indawo eqediwe, indawo yokuhlobisa indlu, indawo yokuvuselela indlu endala kanye nezinguquko zabo yizici eziyinhloko ezithinta isidingo se-MHEC emakethe yasekhaya. Kusukela ngo-2021, ngenxa yomthelela wobhubhane olusha lwenyumoniya, ukulawulwa kwenqubomgomo yezindawo ezithengiswayo, kanye nobungozi bezinkampani ezithengisa izindlu nezindlu, ukuchuma kwemboni yezindlu zaseChina kwehlile, kodwa imboni yezindlu nezindlu iseyimboni ebalulekile ekuthuthukisweni komnotho waseChina. Ngaphansi kwezimiso eziphelele "zokucindezela", "ukuvimbela isidingo esingenangqondo", "ukusimamisa amanani entengo yomhlaba, ukusimamisa izintengo zezindlu, kanye nokuqinisa okulindelekile", kugcizelela ukugxila ekulungiseni ukwakhiwa kokuhlinzekwa kwempahla yesikhathi esimaphakathi neside, kuyilapho kugcinwa ukuqhubeka, ukuzinza, nokungaguquguquki kwezinqubomgomo zokulawula, kanye nokuthuthukisa imakethe yezindawo ezithengiswayo yesikhathi eside. Indlela yokuphatha ephumelelayo yokuqinisekisa intuthuko yesikhathi eside, ezinzile futhi enempilo yemakethe yezindlu nezindlu. Esikhathini esizayo, ukuthuthukiswa kwemboni yezindlu ezithengiswayo kuzovame ukuthuthukiswa kwekhwalithi ephezulu ngekhwalithi ephezulu kanye nesivinini esiphansi. Ngakho-ke, ukwehla kwamanje ekuchumeni kwemboni yezindlu ezithengiswayo kubangelwa ukulungiswa kwemboni ngezigaba ngenqubo yokungena enqubweni yokuthuthukiswa okunempilo, futhi imboni yezindlu ezithengiswayo isenayo indawo yokuthuthukiswa esikhathini esizayo. Ngasikhathi sinye, ngokohlelo lwe-14th lweminyaka emihlanu lweNational Economic and Social Development kanye ne-2035 Long-term Goal Outline, kuhlongozwa ukuthi kuguqulwe indlela yokuthuthukiswa kwamadolobha, okuhlanganisa ukusheshisa ukuvuselelwa kwamadolobha, ukuguqula nokuthuthukisa imiphakathi emidala, amafekthri amadala, amadala. Ukwanda kwesidingo sezinto zokwakha ekuvuselelweni kwezindlu ezindala nakho kuyisiqondiso esibalulekile sokwandisa indawo yemakethe ye-MHEC esikhathini esizayo.

Ngokwezibalo ze-China Cellulose Industry Association, kusukela ngo-2019 kuya ku-2021, umkhiqizo we-MHEC ngamabhizinisi afuywayo wawungamathani angama-34,652, amathani angama-34,150 kanye namathani angama-20,194 ngokulandelana, kanti umthamo wokuthengisa wawungamathani angama-32,531, angama-33,5200 kuya phansi, ukwehla kuye phezulu. umkhuba. Isizathu esikhulu yilesoI-MHECkanye ne-HPMC inemisebenzi efanayo, futhi isetshenziselwa ikakhulukazi izinto zokwakha ezifana nodaka. Kodwa-ke, izindleko nentengo yokuthengisa ye-MHEC iphakeme kunaleyo ye-I-HPMC. Esimweni sokukhula okuqhubekayo kwamandla okukhiqiza we-HPMC yasekhaya, isidingo semakethe se-MHEC sehlile. Ngo-2019 Ngo-2021, ukuqhathanisa phakathi kokuphumayo kwe-MHEC ne-HPMC, ivolumu yokuthengisa, intengo emaphakathi, njll.
