Ngokutsho kwe "China Cellulose Ether Industry Research and Investment Forecast Report (2022 Edition)" ekhutshwe nguLi mu Information Consulting, i-cellulose iyona nxalenye ephambili yeendonga zeeseli zezityalo kunye neyona polysaccharide isasazwe kakhulu kwaye ininzi kakhulu kwindalo.Ibalela ngaphezulu kwe-50% yekhabhoni yomxholo wezityalo.Phakathi kwabo, umxholo we-cellulose wekotoni usondele kwi-100%, owona mthombo we-cellulose wendalo ococekileyo.Ngokhuni ngokubanzi, i-cellulose i-akhawunti ye-40-50%, kwaye kukho i-10-30% ye-hemicellulose kunye ne-20-30% ye-lignin.
Ushishino lwe-cellulose ether lwangaphandle lukhulile, kwaye lulawulwa ngamashishini amakhulu afana neDow Chemical, Ashland, kunye neShin-Etsu.Umthamo wokuvelisa i-cellulose ether yeenkampani ezinkulu zangaphandle umalunga neetoni ezingama-360,000, apho iShin-Etsu yaseJapan kunye neDow yaseUnited States zombini inomthamo wemveliso omalunga neetoni eziyi-100,000, iAshland 80,000 yeetoni, kunye neLotte ngaphezulu kweetoni ezingama-40,000 (ukufunyanwa kweSamsung. -amashishini anxulumeneyo), abavelisi abane abaphezulu be-akhawunti ye-Production umthamo ngaphezu kwe-90% (ngaphandle kwamandla okuvelisa e-China).Inani elincinci lemveliso ye-pharmaceutical-grade, imveliso yokutya kunye ne-high-end-grade-grade-grade cellulose ethers efunekayo kwilizwe lam ibonelelwa ngamashishini angaphandle aziwayo.
Okwangoku, uninzi lwamandla emveliso yezinto eziqhelekileyo zokwakha-ibakala le-cellulose ethers eyandisiweyo e-China iye yaqinisa ukhuphiswano lweemveliso zomgangatho ophantsi wokwakha, ngelixa iimveliso zamayeza kunye nokutya okunemiqobo ephezulu yobugcisa iseyibhodi emfutshane ishishini lelizwe lam le-cellulose ether.
Umgangatho kunye nomthamo wemveliso ye-carboxymethyl cellulose kunye neemveliso zayo zetyuwa kwilizwe lam ziphuculwe kakhulu kwiminyaka yakutshanje, kwaye umthamo wokuthumela ngaphandle unyuke unyaka nonyaka.Imfuno yemarike yangaphandle ixhomekeke ikakhulu kurhwebo lwelizwe lam ngaphandle, kwaye imarike igcwele.Igumbi lokukhula kwexesha elizayo lilinganiselwe.
I-Nonionic cellulose ethers, kuquka i-hydroxyethyl, i-propyl, i-methylcellulose kunye ne-derivatives yazo, inethemba elihle lemarike kwixesha elizayo, ngokukodwa kwizicelo eziphezulu, ezisenendawo enkulu yokuphuhlisa imarike.Okufana namayeza, ipeyinti yodidi oluphezulu, iiseramikhi zodidi oluphezulu, njl.njl. kusafuneka zingeniswe kumazwe angaphandle.Kusekho indawo eninzi yokuphucula kwinqanaba lobugcisa bemveliso kunye nophando kunye nophuhliso, kwaye kukho namathuba amakhulu otyalo-mali.
Okwangoku, inqanaba lezixhobo zoomatshini kwinkqubo yokucoca yasekhaya liphantsi, elithintela kakhulu uphuhliso loshishino.Ukungcola okuphambili kwimveliso yi-sodium chloride.Ngaphambili, i-centrifuges enemilenze emithathu yayisetyenziswa ngokubanzi kwilizwe lam, kwaye inkqubo yokuhlanjululwa yayiyimisebenzi engapheliyo, eyayinzima kakhulu, idla amandla kunye nezinto eziphathekayo.Umgangatho wemveliso nawo kunzima ukuphucula.Uninzi lwemigca emitsha yemveliso ingenise izixhobo zangaphandle ezihambele phambili zokuphucula umgangatho wezixhobo, kodwa kusekho umsantsa phakathi kwe-automation yomgca wemveliso wonke kunye namazwe angaphandle.Uphuhliso lwexesha elizayo loshishino lunokuqwalasela ukudityaniswa kwezixhobo zangaphandle kunye nezixhobo zasekhaya, kunye nezixhobo zokungenisa impahla kwiikhonkco eziphambili zokuphucula ukuzenzekelayo komgca wemveliso.Xa kuthelekiswa neemveliso ze-ionic, ii-ethers ze-cellulose ezingenayo i-ionic zineemfuno eziphezulu zobuchwepheshe, kwaye kungxamisekileyo ukunqumla imiqobo yobugcisa kwi-teknoloji yokuvelisa kunye nokwandiswa kwesicelo.
