Inkampani yaseKima iyimboni ye-cellulose ether esezingeni eliphezulu eChina. Ikhiqiza amabanga ahlukene e-cellulose ether kanye ne-cellulose ether eshintshiwe.
I-Cellulose EtherIsibikezelo Semakethe Sokuphuma Kwaso ngo-2022:
Ngo-2021, ukusetshenziswa komhlaba wonke kwama-cellulose ethers, ama-polymers ancibilikayo emanzini akhiqizwa ukuguqulwa kwamakhemikhali e-cellulose, kwakuseduze namathani ayizigidi ezingu-1.1. Engqikithini yokukhiqizwa kwe-cellulose ether yomhlaba wonke ngo-2021, ama-43% avela e-Asia (i-China yabalelwa ku-79% wokukhiqiza wase-Asia), iNtshonalanga Yurophu yaba ngama-36%, kanti iNyakatho Melika yaba ngu-8%. ukusetshenziswa kwama-cellulose ethers kulindeleke ukuthi kukhule ngesilinganiso sonyaka se-2.9% kusukela ngo-2021 kuya ku-2023, ngokukhula kwesidingo ezimakethe ezivuthiwe eNyakatho Melika naseNtshonalanga Yurophu kube ngaphansi kwesilinganiso somhlaba, ku-1.2% no-1.3%, ngokulandelana. , kuyilapho izinga lokukhula kwesidingo e-Asia nase-Oceania lizoba phezulu kunesilinganiso somhlaba wonke, ngo-3.8%; Izinga lokukhula kwesidingo saseShayina lingu-3.4%, kanti izinga lokukhula eCentral naseMpumalanga Yurophu kulindeleke ukuthi libe ngu-3.8%.
Isifunda esisetshenziswa kakhulu i-cellulose ether emhlabeni ngo-2022 yi-Asia, ebalwa ku-40% wengqikithi esetshenziswayo, kanti i-China ingamandla amakhulu okushayela. INtshonalanga Yurophu kanye neNyakatho Melika zenza u-19% kanye no-11% wokusetshenziswa komhlaba wonke, ngokulandelana. I-Carboxymethyl cellulose (CMC) yabalelwa ku-50% wengqikithi yokusetshenziswa kwama-cellulose ethers ngo-2022, kodwa izinga lokukhula kwayo kulindeleke ukuba libe ngaphansi kunalelo lama-cellulose ethers ewonke esikhathini esizayo. I-Methyl cellulose/hydroxypropyl methyl cellulose (MC/HPMC) ibalwa ku-33% wengqikithi yokusetshenziswa, i-hydroxyethyl cellulose (HEC) ibalwa ku-13%, kanti amanye ama-cellulose ethers abalelwa ku-3%.
Ama-cellulose ether asetshenziswa kakhulu njengama-thickeners, ama-binders, ama-emulsifiers, ama-humectants nama-ejenti okulawula i-viscosity. Izinhlelo zokusebenza zifaka ama-sealant nama-grouts, imikhiqizo yokudla, amapende nama-coatings, nemithi kadokotela kanye nezithasiselo zokudla okunomsoco. Ama-cellulose ether ahlukahlukene aphinde aqhudelane namanye ezimakethe eziningi zohlelo lokusebenza kanye neminye imikhiqizo enezici ezifanayo, njengamapholima okwenziwa ancibilika emanzini kanye namapholima 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. Ukukhethwa kokugcina kwe-polymer yohlelo oluthile kuzoncika ekuhwebeni phakathi kokutholakala, ukusebenza kanye nentengo, kanye nempumelelo yokusetshenziswa.
Ngo-2022, imakethe yomhlaba wonke ye-carboxymethyl cellulose (CMC) yafinyelela kumathani angama-530,000, engahlukaniswa ngokwezigaba zezimboni (isixazululo sesitoko), ibanga elihlanjululwe kancane kanye nebanga lokuhlanzeka okuphezulu. Ukusetshenziswa kokugcina okubaluleke kakhulu kwe-CMC okokuhlanza, esebenzisa i-CMC yezinga lezimboni, ehlanganisa cishe u-22% wokusetshenziswa; izicelo zenkundla kawoyela zibalelwa ku-20%; futhi izithasiselo zokudla zibalelwa ku-13%. Ezifundeni eziningi, izimakethe ezibalulekile ze-CMC sezivuthiwe, kodwa isidingo esivela embonini kawoyela siyaguquguquka futhi sihambisana nezintengo zikawoyela. I-CMC iphinde ibhekane nokuncintisana kweminye imikhiqizo, efana nama-hydrocolloid anganikeza ukusebenza okuphezulu kwezinye izinhlelo zokusebenza. Isidingo sama-cellulose ether ngaphandle kwe-CMC sizoqhutshwa ukusetshenziswa kokuphela kokwakha, okuhlanganisa ukumbozwa kwendawo, kanye nokudla, imithi kanye nezicelo zokunakekela komuntu siqu.
Imakethe yezimboni ze-CMC isahlukene phakathi, abakhiqizi abaphezulu aba-5 babalelwa ku-22% kuphela wesamba esiphelele. Njengamanje, abakhiqizi be-CMC abasezingeni lezimboni baseShayina baphethe imakethe, babala u-48% wawo wonke umthamo. Imakethe ye-CMC yezinga elihlanzekile igxile kakhulu ekukhiqizeni, abakhiqizi abahlanu abaphezulu bebonke baphethe u-53% wamandla okukhiqiza.
Indawo yokuncintisana ye-CMC ihlukile kuneyamanye ama-cellulose ether, anezithiyo eziphansi zokungena, ikakhulukazi emikhiqizweni ye-CMC yezinga lezimboni enobumsulwa buka-65% kuya ku-74%. Imakethe yemikhiqizo enjalo ihlukaniswe kakhulu futhi ilawulwa abakhiqizi baseShayina. Imakethe ye-CMC yezinga elihlanzekile igxile kakhulu, ngobumsulwa obungama-96% noma ngaphezulu. Ngo-2022, ukusetshenziswa komhlaba wonke kwama-cellulose ethers ngaphandle kwe-CMC kwakungamathani angu-537,000, futhi izicelo eziyinhloko kwakuyizicelo zemboni ezihlobene nokwakhiwa, ezibalelwa ku-47%; izicelo zemboni yezokudla nemithi zibalelwe ku-14%; imboni yezingubo ezingaphezulu ibalwa ku-12%. Ezinye izimakethe ze-cellulose ether zigxile kakhulu, abakhiqizi abaphezulu aba-5 bebonke babalelwa ku-57% womthamo womhlaba.
Sekukonke, amathuba okusetshenziswa kwama-cellulose ethers embonini yokudla neyokunakekelwa komuntu siqu azogcina umfutho wokukhula. Njengoba isidingo sabathengi sokudla okunempilo okunamafutha aphansi kanye nokuqukethwe ushukela sizoqhubeka sikhula, ukuze kugwenywe izinto ezingase zibe khona (ezifana ne-gluten), kuzoba namathuba emakethe ama-cellulose ethers, anganikeza ukusebenza okufunayo, Futhi akuphazamisi ukunambitheka. noma ukuthungwa. Kwezinye izinhlelo zokusebenza, ama-cellulose ether aphinde abhekane nokuncintisana okuvela kukuqina okutholakala ekuvubeleni, njengezinsini zemvelo eziningi.
