I-non-ionic cellulose ether yikhemikhali ebalulekileyo efunekayo kushishino lwezixhobo zokwakha kunye noshishino lokugquma. Okwangoku, phantsi kwemvelaphi yokwanda okuqhubekayo kwexabiso elipheleleyo lemveliso yoshishino lokwakha lwasekhaya kunye nokwanda okuqhubekayo kwemarike yokugquma, imfuno yayo yemarike iyaqhubeka nokukhula.
I-Cellulose ether ibhekisa kwi-polymer compound enesakhiwo se-ether esenziwe nge-cellulose. Iyanyibilika emanzini, inyibilikisa isisombululo se-alkali kunye ne-organic solvent, kwaye ine-thermos-plasticity. Isetyenziswa kakhulu ekutyeni, kumayeza, kwiikhemikhali zemihla ngemihla, kulwakhiwo, kwilaphu, kwi-petroleum, kwikhemikhali, isetyenziswa kakhulu kwiingubo, kwi-elektroniki nakwezinye iindawo. Ngokweempawu ezahlukeneyo ze-ionization, ii-cellulose ethers zinokwahlulwa zibe ziindidi ezintathu: ii-non-ionic cellulose ethers, ii-ionic cellulose ethers, kunye nee-mixed cellulose ethers.
Xa kuthelekiswa nee-ether ze-cellulose ze-ionic kunye ne-mixed, ii-ether ze-cellulose ze-non-ionic zinokumelana ngcono nobushushu, ukumelana netyuwa, ukunyibilika kwamanzi, uzinzo lweekhemikhali, iindleko eziphantsi kunye nenkqubo evuthiweyo, kwaye zingasetyenziswa njengee-arhente zokwenza ifilimu, ii-Emulsifiers, ii-thickeners, ii-arhente zokugcina amanzi, ii-binders, iziqinisi kunye nezinye izongezo zeekhemikhali zisetyenziswa kakhulu ekwakheni, kwiingubo, kwiikhemikhali zemihla ngemihla, ekutyeni, kwiindwangu nakwezinye iindawo, kwaye imakethi inamathuba abanzi ophuhliso. Okwangoku, ii-ether ze-cellulose ze-non-ionic eziqhelekileyo ziquka i-hydroxypropyl methyl (HPMC), i-hydroxyethyl methyl (HEMC), i-methyl (MC), i-hydroxypropyl (HPC), i-hydroxyethyl (HEC) njalo njalo.
I-Nonionic cellulose ether yikhemikhali ebalulekileyo efunekayo kushishino lwezixhobo zokwakha kunye noshishino lwezogquma. Okwangoku, imfuno yemarike yayo iyaqhubeka nokukhula phantsi kokukhula okuqhubekayo kwexabiso elipheleleyo lemveliso yoshishino lokwakha lwasekhaya kunye nokwanda okuqhubekayo kwemarike yezogquma. Ngokwedatha evela kwi-National Bureau of Statistics, ixabiso elipheleleyo lemveliso yoshishino lokwakha lwesizwe kwiikota ezintathu zokuqala zika-2022 yayiyi-20624.6 yeebhiliyoni zeerandi, ukunyuka kwe-7.8% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo. Kulo mongo, ngokutsho kwe-"2023-2028 China Nonionic Cellulose Ether Industry Application Market Demand and Development Opportunity Report" ekhutshwe yi-Xin si jie Industry Research Center, umthamo wentengiso yemarike ye-nonionic cellulose ether yasekhaya ngo-2022 iya kufikelela kwiitoni ezili-172,000, ukunyuka konyaka nonyaka kwe-2.2%.
Phakathi kwazo, i-HEC yenye yeemveliso eziphambili kwimarike yasekhaya ye-non-ionic cellulose ether. Ibhekisa kwimveliso yeekhemikhali elungiselelwe nge-cotton pulp njengezinto eziluhlaza ngokusebenzisa i-alkalizing, i-etherification, kunye ne-post-treatment. Isetyenziswe ekwakheni, eJapan, njl. Iikhemikhali, ukhuseleko lokusingqongileyo kunye nezinye iindawo zingasetyenziswa kakhulu. Iqhutywa kukukhula okuqhubekayo kwemfuno, inqanaba lobuchwepheshe bemveliso yamashishini asekhaya e-HEC lihlala liphucuka. Amashishini amaninzi aphambili aneenzuzo zobuchwepheshe kunye nobukhulu avele, njenge-Yi Teng New Materials, i-Yin Ying New Materials, kunye ne-TAIAN Rui tai, kwaye ezinye zeemveliso eziphambili zala mashishini zifikelele kwinqanaba eliphezulu lamazwe ngamazwe. Iqhutywa kuphuhliso olukhawulezileyo lwamacandelo emarike kwixesha elizayo, umkhwa wophuhliso lweshishini lasekhaya le-non-ionic cellulose ether uya kuba mhle.
Abahlalutyi beshishini le-Xin Si Jie bathi i-non-ionic cellulose ether luhlobo lwezinto ze-polymer ezisebenza kakuhle kwaye zisetyenziswa ngokubanzi. Ngenxa yophuhliso olukhawulezayo lwemarike yayo, inani lamashishini asekhaya kweli candelo liyanda. Amashishini aphambili aquka 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.njl., ukhuphiswano lwemarike luya lusanda. Kule meko, ukuhambelana kweemveliso ze-non-ionic cellulose ether zasekhaya kuya kusanda. Kwixesha elizayo, iinkampani zasekuhlaleni kufuneka zikhawulezise uphando kunye nophuhliso lweemveliso eziphezulu nezahlukeneyo, kwaye eli shishini linendawo enkulu yokukhula.
