I-ether ye-cellulose engeyiyo i-ionic yinto ebalulekileyo yeekhemikhali ezifunekayo kwishishini lezinto zokwakha kunye noshishino lokugqoka. Okwangoku, phantsi kwemvelaphi yokunyuka ngokuqhubekayo kwixabiso elipheleleyo lemveliso yoshishino lokwakha lwasekhaya kunye nokwandiswa okuqhubekayo kweemarike zokugubungela, imfuno yayo yemarike iyaqhubeka ikhula.
I-ether ye-cellulose ibhekisela kwikhompawundi ye-polymer enesakhiwo se-ether esenziwe nge-cellulose. Iyanyibilika emanzini, ixutywe nesisombululo sealkali kunye ne-organic solvent, kwaye ine-thermos-plasticity. Isetyenziswa ngokubanzi kukutya, amayeza, imichiza yemihla ngemihla, ulwakhiwo, i-textile, i-petroleum, ikhemikhali, isetyenziswa kakhulu kwiingubo, i-electronics kunye nezinye iindawo. Ngokweempawu ezahlukeneyo ze-ionization, ii-ether ze-cellulose zinokwahlulwa zibe ngamacandelo amathathu: i-non-ionic cellulose ethers, i-ionic cellulose ethers, kunye ne-ethers ye-cellulose edibeneyo.
Xa kuthelekiswa ne-ionic kunye ne-ethers ye-cellulose edibeneyo, i-ethers ye-cellulose e-non-ionic inokumelana nobushushu obungcono, ukumelana netyuwa, ukunyibilika kwamanzi, ukuzinza kweekhemikhali, iindleko eziphantsi kunye nenkqubo evuthiweyo, kwaye inokusetyenziswa njengee-agent ezenza ifilimu, i-Emulsifiers, i-thickeners, ukugcina amanzi. Iiarhente, izibophelelo, izinzisi kunye nezinye izongezo zekhemikhali zisetyenziswa ngokubanzi kulwakhiwo, iingubo, iikhemikhali zemihla ngemihla, ukutya, amalaphu kunye namanye amasimi. Imarike inamathuba abanzi ophuhliso. Okwangoku, i-ethers ye-cellulose ye-non-ionic eqhelekileyo ibandakanya i-hydroxypropyl methyl (HPMC), i-hydroxyethyl methyl (HEMC), i-methyl (MC), i-hydroxypropyl (HPC), i-hydroxyethyl (HEC) njalo njalo.
I-Nonionic cellulose ether yinto ebalulekileyo yekhemikhali efunwa ngushishino lwezixhobo zokwakha kunye neshishini lokugubungela. Okwangoku, imfuno yemarike yayo iyaqhubeka nokukhula phantsi kwemvelaphi yokunyuka okuqhubekayo kwixabiso elipheleleyo lemveliso yoshishino lokwakha lwasekhaya kunye nokwandiswa okuqhubekayo kweemarike zokugquma. Ngokweenkcukacha ezisuka kwi-National Bureau of Statistics, ixabiso lilonke lemveliso yoshishino lokwakha lesizwe kwikota ezintathu zokuqala zowama-2022 laliyi-20624.6 yeebhiliyoni zeeyuan, ukunyuka nge-7.8% xa kuthelekiswa nexesha elifanayo kulo nyaka uphelileyo. Kulo mongo, ngokwe "2023-2028 China Nonionic Cellulose Etere ISicelo seMfuno yeMarike yeSicelo kunye neNgxelo yoPhuhliso lweThuba loPhando" ekhutshwe yi-Xin si jie IZiko loPhando loShishino, umthamo wentengiso yemarike yasekhaya ye-nonionic cellulose ether ngo-2022 iya kufikelela kwi-172,000 tons. , ukunyuka konyaka nonyaka nge-2.2%.
Phakathi kwabo, i-HEC yenye yeemveliso eziqhelekileyo kwimarike yasekhaya engeyiyo ionic cellulose ether. Ibhekisa kwimveliso yeekhemikhali elungiswe kwi-cotton pulp njengento ekrwada ngokusebenzisa i-alkalization, i-etherification, kunye nasemva konyango. Isetyenziswe ekwakhiweni, eJapan, njl njl. Imichiza, ukukhuselwa kwendalo kunye nezinye iindawo zingasetyenziswa ngokubanzi. Iqhutywa kukukhula okuqhubekayo kwemfuno, inqanaba letekhnoloji yemveliso yamashishini e-HEC asekhaya ahlala ephucuka. Amashishini amaninzi ahamba phambili kunye neteknoloji kunye neenzuzo zesikali ziye zavela, ezifana ne-Yi Teng New Materials, iYin Ying New Materials, kunye ne-TAIAN Rui tai, kwaye ezinye zeemveliso eziphambili zala mashishini zifikelele kwinqanaba lamazwe ngamazwe. inqanaba eliphezulu. Ukuqhutywa luphuhliso olukhawulezayo lwamacandelo emarike kwixesha elizayo, uphuhliso lweshishini lasekhaya le-non-ionic cellulose ether liya kuba lihle.
Abahlalutyi boshishino lweXin Si Jie bathi i-ether ye-cellulose engeyiyo i-ionic luhlobo lwemathiriyeli yepolymer esebenza ngokugqwesileyo kunye nokusetyenziswa okubanzi. Iqhutywe kuphuhliso olukhawulezayo lweemarike zayo, inani lamashishini asekhaya kule ndawo liyanda. Amashishini aphambili abandakanya i-Hebei SHUANG NIU, i-Tai An Rui Tai, i-Shandong Yi Teng, i-Shang Yu Chuang Feng, i-North Tian Pu, i-Shandong He da, njl., ukhuphiswano lweemarike luba lubi kakhulu. Kulo mongo, i-homogeneity yeemveliso ze-ether ze-cellulose zasekhaya ezingenayo i-ionic ziba ngakumbi kwaye zivelele. Kwixesha elizayo, iinkampani zasekhaya kufuneka zikhawuleze uphando kunye nophuhliso lweemveliso eziphezulu kunye nezahlulo, kwaye imboni inegumbi elikhulu lokukhula.
