Ngokombiko wakamuva we-IHS Markit, ukusetshenziswa komhlaba wonke kwe-i-cellulose ether-i-polymer encibilikayo emanzini ekhiqizwa ukuguqulwa kwamakhemikhali we-cellulose-iseduze namathani ayizigidi ezingu-1.1 ngo-2018. Engqikithini yokukhiqizwa kwe-cellulose ether yomhlaba wonke ngo-2018, i-43% yavela e-Asia (i-China yabalelwa ku-79% wokukhiqiza wase-Asia), iNtshonalanga Yurophu yaba ngu-36%, kanti iNyakatho Melika ibalwa ngo-8%. Ngokusho kwe-IHS Markit, ukusetshenziswa kwe-cellulose ether kulindeleke ukuthi kukhule ngesilinganiso sonyaka se-2.9% kusukela ku-2018 kuya ku-2023. Phakathi nalesi sikhathi, izinga lokukhula kwesidingo ezimakethe ezivuthiwe eNyakatho Melika naseNtshonalanga Yurophu lizoba ngaphansi kwesilinganiso somhlaba, 1.2% no-1.3% ngokulandelana. , kuyilapho izinga lokukhula kwesidingo e-Asia nase-Oceania lizoba phezulu kunesilinganiso somhlaba wonke, ku-3.8%; izinga lokukhula kwesidingo e-China lizoba ngu-3.4%, futhi izinga lokukhula eCentral naseMpumalanga Yurophu kulindeleke ukuthi libe ngu-3.8%.
Ngo-2018, isifunda esisetshenziswa kakhulu i-cellulose ether emhlabeni yi-Asia, esibalelwa ku-40% wengqikithi esetshenziswayo, kanti i-China ingamandla amakhulu okushayela. INtshonalanga Yurophu kanye neNyakatho Melika babalelwa ku-19% kanye no-11% wokusetshenziswa komhlaba wonke, ngokulandelana.I-Carboxymethyl cellulose (CMC)kubalwe u-50% wengqikithi yokusetshenziswa kwama-cellulose ethers ngo-2018, kodwa izinga lokukhula kwawo kulindeleke ukuba libe ngaphansi kunalelo le-cellulose ethers lilonke esikhathini esizayo.I-Methylcellulose(MC) i-hydroxypropyl methyl cellulose (HPMC)kubalwe u-33% wokusetshenziswa okuphelele,i-hydroxyethyl cellulose (HEC)abalwe ku-13%, kanti amanye ama-cellulose ethers abalelwa ku-3%.
Ngokwalo mbiko, ama-cellulose ether asetshenziswa kakhulu ezintweni eziwugqinsi, izinto zokunamathisela, okokufanisa ama-emulsifiers, ama-humectants, nama-ejenti okulawula i-viscosity. Izinhlelo zokusebenza zifaka ama-sealant nama-grouts, ukudla, amapende nama-coatings, kanye nemithi kadokotela kanye nezithako zokudla okunomsoco. Ama-cellulose ether ahlukahlukene nawo ancintisana namanye ezimakethe eziningi zohlelo lokusebenza, kanye neminye imikhiqizo enemisebenzi efanayo, njengama-polymers okwenziwa ancibilika emanzini kanye nama-polymer emvelo ancibilika emanzini. Ama-polymer okwenziwa ancibilika emanzini ahlanganisa ama-polyacrylates, ama-polyvinyl alcohols, nama-polyurethanes, kuyilapho ama-polymer emvelo ancibilika emanzini ikakhulukazi ahlanganisa i-xanthan gum, i-carrageenan, nezinye izinsini. Kuhlelo lokusebenza oluthile, i-polymer umthengi ekugcineni ayikhethayo kuzoncika ekuhwebeni phakathi kokutholakala, ukusebenza kanye nentengo, kanye nomthelela wokusetshenziswa.
Ngo-2018, imakethe yomhlaba wonke ye-carboxymethylcellulose (CMC) yafinyelela kumathani angama-530,000, engahlukaniswa ngokwezigaba zezimboni (isixazululo sesitoko), ibanga elihlanzwe kancane kanye nebanga eliphakeme. Ukusetshenziswa kokugcina okubaluleke kakhulu kwe-CMC okokuhlanza, kusetshenziswa i-CMC yezinga lezimboni, ebalwa cishe ngama-22% okusetshenziswa; isicelo senkundla kawoyela esibalelwa ku-20%; izithasiselo zokudla zibalelwa ku-13%. Ezifundeni eziningi, izimakethe eziyinhloko ze-CMC sezivuthiwe, kodwa isidingo esivela embonini kawoyela siyaguquguquka futhi sixhumene nezintengo zikawoyela. I-CMC iphinde ibhekane nokuncintisana kweminye imikhiqizo, efana nama-hydrocolloids, anganikeza ukusebenza okuphezulu kwezinye izinhlelo zokusebenza. Isidingo se-cellulose ethers ngaphandle kwe-CMC sizoqhutshwa ukusetshenziswa kokuphela kokwakhiwa, okuhlanganisa ukumbozwa kwendawo, kanye nokudla, izinhlelo zokusebenza zemithi nezokunakekelwa komuntu siqu, kusho i-IHS Markit.
Ngokombiko we-IHS Markit, imakethe yezimboni ze-CMC isahlukene phakathi, kanti abakhiqizi abakhulu abahlanu benza u-22% kuphela wesamba esiphelele. Njengamanje, abakhiqizi be-CMC abasezingeni lezimboni baseShayina baphethe imakethe, benza ama-48% yenani eliphelele. Ukukhiqizwa kwemakethe ye-CMC yebanga lokuhlanza kugxile kakhulu, futhi abakhiqizi abakhulu abahlanu banamandla okukhiqiza angama-53%.
Isimo sokuncintisana se-CMC sihlukile kunesamanye ama-cellulose ether. Umkhawulo uphansi uma kuqhathaniswa, ikakhulukazi emikhiqizweni ye-CMC yezinga lezimboni enobumsulwa obungu-65%~74%. Imakethe yemikhiqizo enjalo ihlukaniswe kakhulu futhi ilawulwa abakhiqizi baseShayina. Imakethe yebanga elihlanzekileI-CMCigxile kakhulu, enobumsulwa obungama-96% noma ngaphezulu. Ngo-2018, ukusetshenziswa komhlaba wonke kwama-cellulose ethers ngaphandle kwe-CMC kwakungamathani angama-537,000, ikakhulukazi asetshenziswa ezimbonini ezihlobene nokwakhiwa, okulinganiselwa ku-47%; izicelo zemboni yezokudla nemithi zibalelwe ku-14%; imboni yokumboza ingaphezulu ibambe u-12%. Imakethe yamanye ama-cellulose ethers igxile kakhulu, abakhiqizi abahlanu abaphezulu bebonke babalelwa ku-57% wamandla okukhiqiza emhlabeni jikelele.
Sekukonke, amathuba okusetshenziswa kwama-cellulose ethers embonini yokudla neyokunakekelwa komuntu siqu azogcina umfutho wokukhula. Njengoba isidingo sabathengi semikhiqizo yokudla okunempilo enamafutha aphansi kanye nokuqukethwe ushukela kuzoqhubeka nokukhula, ukuze kugwenywe izinto ezingase zibe khona ezifana ne-gluten, ngaleyo ndlela kunikeze amathuba emakethe ama-cellulose ethers, angahlinzeka ngemisebenzi edingekayo, ngaphandle kokuyekethisa ukunambitheka noma ukuthungwa. Kwezinye izinhlelo zokusebenza, ama-cellulose ether aphinde abhekane nokuncintisana okuvela kukuqina okutholakala ekuvubeleni, njengezinsini zemvelo eziningi.
