Unjani isimo semakethe sasekhaya nezangaphandle se-ether engeyona eye-cellulose?

(1)Sibutsetelo semakethe ye-ether ye-gelvuc yomhlaba wonke ye-cellulose:

Ngokombono wokusatshalaliswa kwamandla okukhiqizwa kwamandla omhlaba wonke, ama-43% okukhiqizwa okuphelele kwe-Global Cellulose ether ngo-2018 (China avele ngo-79% wokukhiqizwa kwe-Asia), eNtshonalanga Yurophu yabalwa ngo-36%. Ngokombono we-Global Cellulose Ether Ukudliwa, ukusetshenziswa kwe-gerule komhlaba jikelele ngonyaka we-2018 kungamathani ayizigidi eziyi-1,1. Kusukela ngo-2018 kuya ku-2023, ukusetshenziswa kwe-cellulose ether kuzokhula ngesilinganiso sonyaka esingu-2.9%.

Cishe ingxenye yesigamu senani eliphelele le-Global Cellulose ether I-Cellulose i-Ionic Cellule Cishe ingxenye eyodwa kwezintathu yi-nonic methyl celtule Ukukhula okufunwayo kwe-nonic cellulose Afers kuqhutshwa ikakhulukazi izinhlelo zokusebenza emikhakheni yezinto zokwakha, ukumboza, ukudla, umuthi, kanye namakhemikhali nsuku zonke. Ngokombono wokusatshalaliswa kwesifunda kwemakethe yabathengi, imakethe yase-Asia iyimakethe ekhula ngokushesha kakhulu. Kusukela ngo-2014 kuya ku-2019, izinga lokukhula lonyaka elihlanganisiwe le-CelLose Ether e-Asia lifinyelele ku-8.24%. Phakathi kwazo, isidingo esikhulu e-Asia sivela eChina, sibalwa ngama-23% wesidingo sembulunga yonke.

(2)Ukubuka konke kwemakethe ye-ether ye-ether yasekhaya engenayo:

E-China, i-Ionic Cellulose, izithembiso ezimelelwa yi-CMC zithuthukiswa ngaphambili, zakha inqubo yokukhiqiza evuthiwe kanye nomthamo omkhulu wokukhiqiza. Ngokusho kwedatha ye-IHS, abakhiqizi baseChina bahlale cishe isigamu sendawo yokukhiqiza yomhlaba yemikhiqizo eyisisekelo ye-CMC. Ukuthuthukiswa kwe-nonic cellulose ether kwaqala ngokuhamba kwesikhathi ezweni lami, kepha ijubane lokuthuthuka liyashesha.

Ngokwemininingwane ye-China Cellulose Industry Association, umthamo wokukhiqiza, umphumela kanye nokuthengiswa kwezithambisi ezingezona ezikhona zamabhizinisi asekhaya eChina kusuka ngo-2019 kuya ku-2021 zimi ngokulandelayo:

Ngemuva kweminyaka yentuthuko, imakethe ye-ether ye-ether ye-China engemihle ye-mollulose yenze intuthuko enkulu. Ngo-2021, umthamo wokukhiqiza owenzelwe ukwakhiwa kwe-HPMC ye-Maild-Grade HPMC uzofinyelela amathani angama-117,600, okuphumayo kuzoba amathani ayi-104,300, futhi ivolumu yokuthengisa lizoba ngamathani angama-97,500. Isilinganiso esikhulu sezimboni kanye nezinzuzo zasendaweni ziye zabona ngokuyisisekelo esikhundleni sokufakwa esikhundleni esifuywayo. Kodwa-ke, ngemikhiqizo ye-HEC, ngenxa yokuqalisa sekwedlule isikhathi kwe-R & D kanye nokukhiqizwa ezweni lami, inqubo ekhiqizwayo enzima kanye nezithiyo eziphakeme zobuchwepheshe, umthamo wokukhiqiza, ukukhiqizwa kanye nevolumu yokuthengisa ye-HEC imikhiqizo yasekhaya incane. Kodwa-ke, eminyakeni yamuva nje, njengoba amabhizinisi asekhaya ayaqhubeka ukukhulisa ukutshalwa kwezimali ocwaningweni nasekuthuthukisweni, athuthukise izinga lobuchwepheshe futhi athuthukise amakhasimende aphansi, ukukhiqizwa kanye nokuthengisa sekukhule ngokushesha. Ngokusho kwemininingwane evela e-China Cellulose Industry Association, ngo-2021, amabhizinisi amakhulu asemabhizinisini asezimoneni (afakwa kwizibalo zeNhlangano Yezimboni, injongo yonke) anekhono lokukhiqiza elenzelwe amathani angu-19,000, futhi umqulu wokuthengisa wamathani ayi-16,800. Phakathi kwazo, umthamo wokukhiqiza ukhuphuke ngonyaka ka-72.73% ngonyaka uma uma uqhathaniswa no-2020, okuphumayo kukhuphuke ngonyaka ka-43.41% ngonyaka, futhi ivolumu yokuthengisa lenyuke ngo-40.60% unyaka nonyaka.

Njengesengezo, umthamo wokuthengisa we-HEC uthintwe kakhulu yisidingo semakethe esiphansi. Njengensimu yohlelo lokusebenza ebaluleke kakhulu ye-HEC, imboni yezambane inokuhlangana okuqinile okunamandla nokukhanga kweHec ngokuya ngokukhishwa kanye nokusatshalaliswa kwemakethe. Ngokombono wokusatshalaliswa kwemakethe, imakethe yezimboni ye-Coatings isatshalaliswa kakhulu eJiangsu, uZhejiang naseShanghai e-East China, e-Guangdong eSouth China, iSouthweast Coast, kanye neSichuan eningizimu-ntshonalanga yeChina. Phakathi kwazo, umphumela we-coating eJiangsu, uZhejiang, uShanghai noFujian babalwa cishe ama-32%, nokuthi eSouth China naseGuangdong babalelwa cishe ama-20%. 5 ngenhla. Imakethe yemikhiqizo ye-HEC igxile kakhulu eJiangsu, uZhejiang, eShanghai, eGuangdong naseFujian. I-HEC okwamanje isetshenziswa kakhulu egqokezelwa izakhiwo, kepha ilungele zonke izinhlobo zezingubo ezisuselwa emanzini ngokuya ngezimpawu zalo zomkhiqizo.

Ngo-2021, okuphelele kokukhishwa konyaka kwezimbali zaseChina kulindeleke ukuthi kube cishe amathani ayizigidi ezingama-25,82, kanye nemiphumela yezembatho zezakhiwo kanye nezingubo zezimboni zizoba ngamathani ayizigidi eziyi-7.51. Izambatho ezisuselwa emanzini njengamanje zibalelwa kuma-90% ezimbozo zezakhiwo, futhi mayelana nokubalwa kwama-25%, kulinganiselwa ukuthi ukukhiqizwa kwepende yezwe lami okususelwa kumanzi ngo-2021 kuzoba cishe amathani ayi-11.3365 million. Ngokweqiniso, inani le-HEC elingezwe kumapende asuselwa emanzini angu-0,1% kuye ku-0.5%, libalwa ngokwesilinganiso esingu-0.3%, isidingo sikazwelonke se-Peant-grade hec cishe amathani angama-34,000. Ngokusekelwe ekukhiqizeni okuphelele kwe-37,6 amathani ayizigidi ezingama-97

Ukufingqa, njengamanje, isabelo semakethe sebanga le-coating grade ye-China lisezingeni eliphansi, futhi isabelo semakethe sasekhaya ikakhulukazi sihlala phansi abakhiqizi bamazwe omhlaba, futhi kunesikhala esikhulu sokufaka esikhundleni sasekhaya. Ngokwephuculwa kwekhwalithi yomkhiqizo wasekhaya we-HEC kanye nokwanda kwekhono lokukhiqiza, kuzoqhudelana kakhulu nabakhiqizi bamanye amazwe enkambini ephansi emelelwe yizimbali. Ukungena esikhundleni sasekhaya kanye nomncintiswano wemakethe yamazwe omhlaba kuzoba yinkambiso enkulu yalombo imboni esikhathini esithile ngokuzayo.

I-MHEC isetshenziswa ikakhulukazi emkhakheni wezinto zokwakha. Imvamisa isetshenziswa ku-usimende kasimende ukuthuthukisa ukugcinwa kwayo kwamanzi, yandisa isikhathi sokusetha sikasimende, yehlisa amandla ayo aguqukayo namandla acindezelayo, futhi andise amandla awo ashubile, futhi andise amandla awo abugqilayo. Ngenxa ye-gel iphuzu le-gel yalolu hlobo lomkhiqizo, alusetshenziswa kancane emkhakheni wezimbozo, futhi ikakhulukazi lincintisana ne-HPMC emkhakheni wezinto zokwakha. I-MHEC inephuzu lejeli, kepha liphakeme kune-HPMC, futhi njengoba okuqukethwe kwe-hydroxy ethoxy kukhuphuka, iphuzu laso le-gel liya ekuqondisweni kokushisa okuphezulu. Uma isetshenziswa ngodaka oluxubile, kuyazuzisa ukuthambekela usimende slurry ekuvuseleleni okuphezulu kwe-bulk freen reatechemical ukusabela, kwandise izinga lokugcinwa kwamanzi namandla okubumba ama-slurry neminye imiphumela.

Isilinganiso sokutshala kwemboni yezokwakha, indawo yokwakhiwa kwezindawo, indawo eqediwe, indawo yokuhlobisa indlu, indawo yakudala yokuvuselela indlu kanye nezinguquko zabo yizici eziphambili ezithinta isidingo seM khadi yasekhaya. Kusukela ngo-2021, ngenxa yomthelela wobhubhane olusha lwe-Crown Pneumonia, umthetho wenqubomgomo yezezindawo, kanye nobungozi bezinkampani zezezindlu, kepha imboni yezezakhiwo yaseChina ihlehlisile, kepha imboni yezezakhiwo yaseChina ihlehlisile, kepha imboni yezezakhiwo yaseChina ihlehlisile, kepha imboni yezezakhiwo yaseChina ihlehlisile, kepha imboni yezezakhiwo yaseChina ihlehlisile, kepha imboni yezezakhiwo nezezindlu ziyimboni ebalulekile yentuthuko yezomnotho yaseChina. Ngaphansi kwezimiso eziphelele ze- "Suprepression", "Ukuvimba Ukuchithwa Kwezwe", "Ukuzinza Amanani Emanani Endlu, Ukuqina Kwendlu, Ukugcina Ukugxila Ekuguqukeni Kwezinqubomgomo Zokulawula Okuhlala isikhathi eside, kanye nokuqina kwezinqubomgomo zokulawula, kanye nokwenza ngcono imakethe yezezakhiwo isikhathi eside. Indlela yokuphatha ephumelelayo yokuqinisekisa ukuthuthukiswa kwesikhathi eside, ezinzile nenempilo yemakethe yezezakhiwo. Esikhathini esizayo, ukuthuthukiswa komkhakha wezezakhiwo kuzothambekela ekuthuthukisweni okuseqophelweni eliphezulu ngekhwalithi ephezulu nejubane eliphansi. Ngakho-ke, ukwehla kwamanje ekuchumeni kwemboni yezezakhiwo kubangelwa ukulungiswa kwemboni embonini kwinqubo yokungena kwinqubo enempilo yentuthuko, futhi imboni yezezakhiwo isenendawo yokuthuthuka ngokuzayo. Ngasikhathi sinye, ngokusho kohlelo lwe- "14th lweminyaka emihlanu lokuthuthuka kwezomnotho nakulolu-2035 kanye nohlaka lwezinhlamvu zesikhathi eside", kuhlongozwa ukuguqula indlela yokuvuselelwa kwamadolobha, kufaka phakathi ukusheshisa imiphakathi yasemadolobheni, kanye nokukhulisa imisebenzi yezindawo ezindala njengamabhulokhi amadala kanye nezinye izinhloso. Ukwanda kwesidingo sezinto zokwakha ekwakheni kabusha kwezindlu ezindala nakho kuyindlela ebalulekile yokwanda kwendawo yemakethe ye-MHEC ngokuzayo.

Ngokwezibalo zeChina Cellulose Industry Association, kusukela ngo-2019 kuya ku-2021, umphumela we-MHEC ngamathani asekhaya kwakungamathani angama-34,194 ngamathani angama-32,451 namathani angama-20,411 ngokulandelana, okubonisa ukuthambekela okuphelele. Isizathu esiyinhloko ukuthi i-MHEC ne-HPMC ibe nemisebenzi efanayo, futhi ikakhulukazi isetshenziselwa izinto zokwakha ezifana nodaka. Kodwa-ke, izindleko kanye nentengo yokuthengisa ye-MHEC ziphakeme kunalokho kwe-HPMC. Ngokwesimo sokukhula okuqhubekayo kwekhono lokukhiqizwa kwasekhaya kwe-HPMC, isidingo semakethe se-MHEC sehle. Ngo-2019 ngonyaka ka-2021, ukuqhathanisa phakathi kweMhec kanye ne-HPMC okukhipha, ivolumu yokuthengisa, intengo ephakathi, njll. Iminyaka elandelayo:
