Ucwaningo nokuhlaziywa kwesimo samanje sokuthuthukiswa kwemboni ye-Cellulose ether eShayina. I-Cellulose ether eShayina yaqala sekwephuzile, amazwe athuthukile athuthuka kusenesikhathi imakethe isivuthiwe, njengamanje, amabhizinisi okukhiqiza i-cellulose ether aziwa kakhulu emhlabeni wonke ayimakethe enkulu yomhlaba wonke, aqonda ukusetshenziswa kobuchwepheshe obuthuthukisiwe, uma kuqhathaniswa nabasebenzi bakwamanye amazwe ababandakanyeka ocwaningweni nasekukhiqizweni kwe-cellulose ether eShayina, inani lezindawo zokugcina kanye nochwepheshe abasezingeni eliphezulu, linegebe elithile ocwaningweni nasekuthuthukisweni nasekusetshenzisweni kobuchwepheshe.
Njengoba ukuthuthukiswa kolwazi lokuvikelwa kwemvelo kanye nezinqubomgomo zemvelo eziqinile, izidingo zemvelo zikhuphuka kakhulu zezinto zokwakha, ukumbozwa okuphezulu kokuvikelwa kwemvelo, yinani elikhulu labathengi, kwabangela ukuthuthukiswa okusheshayo kokumbozwa kwezakhiwo eminyakeni yamuva nje, kukhuthaza ukukhula kwesidingo semakethe ye-cellulose ethers ngasikhathi sinye, i-cellulose ether yakhiwe kakhulu yi-ethyl cellulose, i-methyl cellulose, i-methyl cellulose, i-hydroxyethyl cellulose, njll.
Udaka oluxubile olomile lusebenzisa kakhulu i-cellulose encibilika emanzini, engahlukaniswa ngohlobo oluncibilika ngokushesha kanye nohlobo lokuncibilika olulibazisekile.
Ngaphezu kwalokho, i-cellulose ether ingasetshenziswa emikhakheni ehlobene kakhulu nathi, njengamabhethri, amazinyo okuxubha, insipho, ukwenza amaphepha, izinto zobumba, izindwangu nokunye.
Ngokusho kwesakhiwo samakhemikhali, ukuhlukaniswa kwezinto ezithatha indawo, kungahlukaniswa kube ama-ether e-anionic, cationic kanye nama-non-ionic.
I-non-ionic cellulose ether isetshenziswa kakhulu kwezokwelapha, ukudla nokuhlola, ukumboza kanye nezinsipho, amakhemikhali ansuku zonke, imboni yokumba uwoyela. Ngokusho kwezibalo zedatha ze-Chinese Cellulose Association, ngo-2012, ukukhiqizwa kwe-non-ionic cellulose ether yaseShayina okungamathani angaba yi-100,000, kuya ku-2018 ukukhiqizwa kwe-non-ionic cellulose ether yaseShayina kwakhula kwafika kumathani angu-300,000. Kunezizathu ezimbili eziyinhloko zentuthuko esheshayo yale mboni:
Ngakolunye uhlangothi, ukuzuza ekuthuthukisweni okusheshayo kokukhula kwedolobha lasekhaya kanye nokukhuthazwa kwezinqubomgomo zikazwelonke, isidingo semakethe semikhiqizo yezinga lezinto zokwakha engeyona i-ionic cellulose ether siyakhula.
Izici ezimbili, ikakhulukazi ukukhiqizwa kwe-cellulose ether okuzimele kanye nezinga locwaningo nentuthuko liyaqhubeka nokuthuthuka, ebangeni lokudla kanye nemithi kanye nemikhiqizo yasekhaya ye-cellulose ether kancane kancane ithatha indawo yesilinganiso sokungeniswa kwamanye amazwe sanda kancane kancane, nge-cellulose ether ekungeneni kwemakethe okuphansi kanye nokudonsa kwamanye amazwe, kulindeleke ukuthi umthamo wemakethe ye-cellulose ether yesikhathi esizayo uqhubeke nokukhula.
Njengamanje, iphethini yemakethe yemboni ye-cellulose ether yaseShayina ihlakazekile, umehluko wemikhiqizo mkhulu, umncintiswano wemakethe wezinga eliphansi uqine kakhulu, ukudla nemithi kanye nezinhlobo zezinga eliphezulu kufinyelele emkhawulweni ophezulu, abakhiqizi abambalwa. Ingabe ibhodi elifushane lemboni ye-cellulose ether yaseShayina.
I-Cellulose ether ngokwensimu yesicelo: Ibanga lokudla kanye nebanga lemithi kanye nebanga lezinto zokwakha kanye namakhemikhali ansuku zonke, isidingo semakethe yezinto zokwakha embonini ye-cellulose ether sikhulu kakhulu, sifinyelela esidingweni semakethe iyonke, kufaka phakathi ukwakhiwa kanye nokumbozwa kanye nensimu ye-PVC ebalelwa ku-80%, kufaka phakathi insimu yokumbozwa ebalelwa ku-60% womhlaba, kwamanye amazwe i-cellulose ether isetshenziswa kabanzi kumakhemikhali ansuku zonke kanye nasemasimini emithi kanye nokudla, ukudla kanye nemithi kanye nezicelo zamakhemikhali zansuku zonke zaseShayina zibalelwa ku-11% kuphela, ngokukhula okuqhubekayo kwensimu yesicelo, isidingo sokusebenza kwe-cellulose ether ensimini siyaqhubeka nokukhula.
Eminyakeni yamuva nje, isidingo semakethe ye-cellulose ether yaseShayina ngokwenethiwekhi eyinhloko ethi “ucwaningo lwemakethe yemboni ye-cellulose ether yaseShayina ka-2019-2024 kanye nombiko wokuhlaziywa kokutshalwa kwezimali kwecebo lokuncintisana” idatha yocwaningo lwemakethe kanye nokuhlaziywa ikhombisa ukuthi ngo-2012, isidingo semakethe ye-cellulose ether yaseShayina esingaphansi kwamathani angu-336,600 engxenyeni yokuqala ka-2016 isidingo se-cellulose ether sifinyelela kumathani angu-314,600, Isidingo semakethe yonyaka singamathani angu-635,100, isidingo semakethe ngo-2019 singaphezu kwamathani angu-800,000, futhi kubikezelwa ukuthi isidingo semakethe ngo-2020 sizoba ngaphezu kwamathani angu-900,000. Umthamo wemakethe ye-cellulose ether yaseShayina ka-2019-2025 uhlanganisa izinga lokukhula lonyaka ukuze kugcinwe ukukhula okungu-3%, isidingo semakethe sizoqhubeka nokwandisa izindawo ezintsha, imakethe yesikhathi esizayo izobonisa ukuthambekela kwesivinini esimaphakathi sokukhula.
