Zvinoenderana neshumo yazvino kubva IHS Markit, kushandiswa kwepasi rose kwecellulose ether-polymer inogadziriswa nemvura inogadzirwa nemakemikari ekugadzirisa cellulose-iri pedyo nemamiriyoni 1.1 emamiriyoni muna 2018. Pahuwandu hwepasi rose cellulose ether kugadzirwa muna 2018, 43% yakabva kuAsia (China yakaverengera 79% yekugadzirwa kweAsia), Western Europe yakaverengera 36%, uye North America yakaverengera 8%. Maererano ne IHS Markit, kushandiswa kwe cellulose ether kunotarisirwa kukura pamwero wegore negore we 2.9% kubva ku2018 kusvika ku 2023. Munguva iyi, kudiwa kwekukura kwemitengo mumisika yakakura muNorth America neWestern Europe ichave yakaderera kudarika chiyero chepasi rose, 1.2% uye 1.3% maererano. , nepo kukura kwekudiwa muAsia neOceania kuchave kwakakwirira kudarika avhareji yepasi rose, pa3.8%; chiyero chekukura kwekudiwa muChina chichava 3.4%, uye chiyero chekukura muCentral neEastern Europe chinotarisirwa kuva 3.8%.
Muna 2018, dunhu rine kushandiswa kukuru kweselulosi ether pasi rose iAsia, inoverengera makumi mana muzana ehuwandu hwekushandisa, uye China ndiyo inonyanya kutyaira. Western Europe neNorth America dzakaverengera 19% uye 11% yekushandiswa kwepasirese, zvichiteerana.Carboxymethyl cellulose (CMC)yakaverengera 50% yehuwandu hwekushandisa kwe cellulose ethers mu2018, asi kukura kwayo kunotarisirwa kuve kwakaderera pane iyo cellulose ethers yakazara mune ramangwana.Methylcellulose (MC) hydroxypropyl methyl cellulose (HPMC)yakaverengera 33% yehuwandu hwekushandisa,hydroxyethyl cellulose (HEC)yakaverengerwa 13%, uye mamwe ma cellulose ether akaverengera anenge 3%.
Sekureva kwemushumo, cellulose ethers anoshandiswa zvakanyanya mukukora, zvinonamira, emulsifiers, humectants, uye viscosity control agents. Kupera kwekushandisa kunosanganisira sealants uye grouts, chikafu, pendi uye machira, pamwe nemishonga yemishonga uye zvinovaka muviri. Yakasiyana-siyana cellulose ethers zvakare inokwikwidzana mumisika yakawanda yekushandisa, uye zvakare nezvimwe zvigadzirwa zvine mabasa akafanana, senge ekugadzira-anonyungudika mvura mapolymers uye echisikigo anonyungudika mvura mapolymer. Synthetic mvura-soluble mapolymers anosanganisira polyacrylates, polyvinyl alcohols, uye polyurethanes, nepo echisikigo-anonyungudika mvura mapolymers anonyanya kusanganisira xanthan chingamu, carrageenan, uye mamwe mazamu. Mune chaiyo application, iyo polymer inozosarudzwa nemutengi zvinoenderana nekutengesa-kusiyana pakati pekuwanikwa, kuita uye mutengo, uye mhedzisiro yekushandisa.
Muna 2018, iyo yakazara yepasi rose carboxymethylcellulose (CMC) musika yakasvika zviuru mazana mashanu nemakumi matatu emakumi matatu ematani, ayo anogona kukamurwa kuita maindasitiri giredhi (stock solution), semi-yakacheneswa giredhi uye yakakwirira-kuchena giredhi. Kunyanya kukosha kwekupedzisira kushandiswa kweCMC ndeye detergent, uchishandisa maindasitiri giredhi CMC, inoverengera inosvika 22% yekudyiwa; Oiri munda application accounting inosvika 20%; chikafu chekuwedzera chinotora chikamu che13%. Mumatunhu mazhinji, misika yekutanga yeCMC yakura, asi kudiwa kubva kuindasitiri yemafuta kune kusagadzikana uye kwakabatana nemitengo yemafuta. CMC inotarisanawo nemakwikwi kubva kune zvimwe zvigadzirwa, senge hydrocolloids, izvo zvinogona kupa hukuru hwekuita mune mamwe maapplication. Kudiwa kwema cellulose ethers kunze kweCMC kuchafambiswa nekushandiswa kwekupedzisira kwekuvaka, kusanganisira machira epamusoro, pamwe nekudya, mishonga yemishonga uye yekuchengeta munhu, IHS Markit yakati.
Sekureva kweiyo IHS Markit mushumo, musika wemaindasitiri weCMC uchiri wakakamukana, nevagadziri vashanu vakuru vanoverengera 22% chete yehuwandu hwese. Parizvino, vagadziri veChinese maindasitiri-giredhi CMC vanotonga pamusika, vachiverengera 48% yehuwandu hwehuwandu. Kugadzirwa kwegiredhi rekucheneswa CMC musika kwakaringana, uye vagadziri vakuru vashanu vane huwandu hwekugadzira huwandu hwe53%.
Nzvimbo yemakwikwi yeCMC yakasiyana neiyo yemamwe cellulose ethers. Chikumbaridzo chakaderera, kunyanya kune maindasitiri-giredhi CMC zvigadzirwa zvine kuchena kwe65% ~ 74%. Musika wezvigadzirwa zvakadaro wakanyanya kupatsanurwa uye unotongwa nevagadziri veChinese. Musika wekucheneswa giredhiCMCyakanyanyisa, iyo ine kuchena kwe96% kana kupfuura. Muna 2018, kushandiswa kwepasi rose kwema cellulose ethers kunze kweCMC kwaive 537,000 matani, ainyanya kushandiswa mumaindasitiri ane chekuita nekuvaka, achiverengera 47%; chikafu neindasitiri yemishonga zvikumbiro zvakaverengerwa 14%; Indasitiri yekupfeka yepasi yakaverengera 12%. Musika wemamwe ma cellulose ethers wakanyanya kutariswa, nevagadziri vashanu vepamusoro pamwe chete vanoverengera 57% yepasi rose kugadzira.
Pakazere, tarisiro yekushandiswa kwema cellulose ethers mumaindasitiri ezvekudya uye ega ega anochengetedza kukura. Sezvo kudiwa kwevatengi kune zvigadzirwa zvekudya zvine hutano zvine mafuta akaderera uye shuga zvirimo zvicharamba zvichikura, kuitira kudzivirira zvingangoita senge gluten, zvichipa mikana yemusika ye cellulose ethers, iyo inogona kupa mabasa anodiwa, pasina kukanganisa kuravira kana kuumbwa. Mune mamwe maapplication, cellulose ethers zvakare inotarisana nemakwikwi kubva kufermentation-inotorwa thickeners, senge akawanda echisikigo gums.
