Ngokutsho kwengxelo yamva nje evela kwi-IHS Markit, ukusetyenziswa kwehlabathi jikelele kwe-cellulose ether-i-polymer e-soluble yamanzi eveliswa yi-chemical modification ye-cellulose-isondele kwi-1.1 yezigidi zeetoni kwi-2018. Kwimveliso ye-cellulose ether yehlabathi jikelele kwi-2018, i-43% yeza. ukusuka e-Asia (i-China yabalelwa kwi-79% yemveliso yase-Asia), iNtshona Yurophu ibalwa kwi-36%, kunye neNyakatho Melika i-8%.Ngokutsho kwe-IHS Markit, ukusetyenziswa kwe-cellulose ether kulindeleke ukuba kukhule kumyinge wonyaka we-2.9% ukusuka kwi-2018 ukuya kwi-2023. Ngeli xesha, izinga lokukhula kweemfuno kwiimarike ezivuthiweyo eMntla Melika naseNtshona Yurophu ziya kuba ngaphantsi kwehlabathi. umndilili, 1.2% kunye 1.3% ngokulandelelanayo., ngelixa izinga lokukhula kwemfuno e-Asia nase-Oceania liya kuba liphezulu kune-avareji yehlabathi, kwi-3.8%;izinga lokukhula kwemfuno e-China iya kuba yi-3.4%, kwaye izinga lokukhula kuMbindi naseMpuma Yurophu kulindeleke ukuba libe yi-3.8%.
Kwi-2018, ummandla onokusetyenziswa kakhulu kwe-cellulose ether emhlabeni yi-Asia, ibalwa kwi-40% yokusetyenziswa okupheleleyo, kwaye i-China iyona nto iqhuba amandla.INtshona Yurophu kunye noMntla Melika babalelwa kwi-19% kunye ne-11% yokusetyenziswa kwehlabathi, ngokulandelanayo.I-Carboxymethyl cellulose (CMC) ibalwa kwi-50% yokusetyenziswa okupheleleyo kwe-cellulose ethers kwi-2018, kodwa izinga lokukhula kwayo kulindeleke ukuba libe ngaphantsi kwe-cellulose ethers ngokubanzi kwixesha elizayo.I-Methylcellulose / hydroxypropyl methyl cellulose (MC / HPMC) ibalwa kwi-33% yokusetyenziswa ngokupheleleyo, i-hydroxyethyl cellulose (HEC) ibalwa kwi-13%, kunye nezinye i-cellulose ethers zibalwa malunga ne-3%.
Ngokutsho kwengxelo, ii-cellulose ethers zisetyenziswa kakhulu kwii-thickeners, adhesives, emulsifiers, humectants, kunye ne-viscosity control agents.Izicelo zokuphela ziquka i-sealants kunye ne-grouts, ukutya, iipeyinti kunye neengubo, kunye neziyobisi ezichazwe ngugqirha kunye nezongezo zokutya.Iintlobo ezahlukeneyo ze-cellulose ethers zikhuphisana enye kwenye kwiimarike ezininzi zesicelo, kunye nezinye iimveliso ezinemisebenzi efanayo, efana neepolima zokwenziwa zamanzi ezinyibilikayo kunye neepolima zendalo ezinyibilikayo emanzini.Iipolymers zokwenziwa kwamanzi ezinyibilikayo zibandakanya iipolyacrylates, iipolyvinyl alcohols, kunye nepolyurethanes, ngelixa iipolima zendalo ezinyibilikayo emanzini ikakhulu ziquka i-xanthan gum, carrageenan, kunye nezinye iintsini.Kwisicelo esithile, apho i-polymer ekhethwa ngumthengi ekugqibeleni iya kuxhomekeka kurhwebo phakathi kokufumaneka, ukusebenza kunye nexabiso, kunye nesiphumo sokusetyenziswa.
Ngo-2018, imakethi ye-carboxymethylcellulose (CMC) iyonke yehlabathi ifikelele kwiitoni ezingama-530,000, ezinokuthi zohlulwe ngokwenqanaba lemizi-mveliso (isisombululo sesitokhwe), ibakala elihlanjululweyo kunye nenqanaba lococeko oluphezulu.Eyona nto ibalulekileyo yokusetyenziswa kwe-CMC sisicoci, kusetyenziswa ibakala leshishini le-CMC, kubalwa malunga ne-22% yokusetyenziswa;ukufakwa kwe-oyile kwibala elimalunga nama-20%;izongezo zokutya zibalelwa malunga ne-13%.Kwimimandla emininzi, iimarike eziphambili zeCMC zivuthiwe, kodwa imfuno evela kushishino lwe-oyile iyaguquguquka kwaye inxulunyaniswe namaxabiso eoyile.I-CMC ijongene nokhuphiswano oluvela kwezinye iimveliso, ezifana ne-hydrocolloids, enokubonelela ngokusebenza okuphezulu kwezinye izicelo.Imfuno ye-cellulose ethers ngaphandle kwe-CMC iya kuqhutywa kukusetyenziswa kokuphela kokwakhiwa, kubandakanywa iingubo ezingaphezulu, kunye nokutya, amayeza kunye nezicelo zokunakekelwa komntu, u-IHS Markit uthe.
Ngokwengxelo ye-IHS Markit, imarike yeshishini le-CMC isaqhekeka, kunye nabavelisi abakhulu abahlanu bathatha kuphela i-22% yomthamo uwonke.Okwangoku, abavelisi baseTshayina abakwinqanaba leshishini leCMC balawula imarike, bebalelwa kwi-48% yomthamo uwonke.Imveliso yomgangatho wokucoca imarike yeCMC igxininiswe, kwaye abavelisi abakhulu abahlanu banomthamo wemveliso we-53%.
Ubume obukhuphisanayo be-CMC bahlukile kuleyo yezinye ii-cellulose ethers.Umda usezantsi kakhulu, ngakumbi kwiimveliso ze-CMC zodidi lwemizi-mveliso ezinobunyulu obungama-65% ~ 74%.Imarike yeemveliso ezinjalo ihlukaniswe ngakumbi kwaye ilawulwa ngabavelisi baseTshayina.Imarike yeCMC yebakala elisulungekileyo igxininiswe ngakumbi, enobunyulu be-96% okanye ngaphezulu.Kwi-2018, ukusetyenziswa kwehlabathi jikelele kwe-cellulose ethers ngaphandle kwe-CMC yayiyi-537,000 yeetoni, ezisetyenziswa kakhulu kumashishini anxulumene nokwakhiwa, kubalelwa kwi-47%;izicelo zoshishino lokutya kunye namayeza zibalelwa kwi-14%;Ushishino lokugquma komhlaba lubalelwa kwi-12%.Imarike yezinye ii-cellulose ethers igxininiswe ngakumbi, kunye nabavelisi abahlanu abaphezulu bebonke babalelwa kwi-57% yomthamo wemveliso yehlabathi.
Ngokubanzi, amathuba okusetyenziswa kwe-cellulose ethers kumashishini okutya kunye nokhathalelo lomntu aya kugcina ukukhula ngokukhawuleza.Njengoko imfuno yabathengi yokutya okunempilo okunempilo kunye namafutha aphantsi kunye nomxholo weshukela uya kuqhubeka nokukhula, ukwenzela ukuba ugweme izinto ezinokuthi zenzeke ezifana ne-gluten, ngaloo ndlela zibonelela ngamathuba emarike ye-cellulose ethers, enokubonelela ngemisebenzi efunekayo, ngaphandle kokunciphisa incasa okanye ukuthungwa.Kwezinye izicelo, i-cellulose ethers ikwajongana nokhuphiswano oluvela kwi-fermentation-derived thickeners, njengeentsini zendalo.
