Iselulosi etherligama eliqhelekileyo kwiintlobo ezahlukeneyo ze-derivatives ezifunyenwe kwi-cellulose yendalo (i-cotton ecocekileyo kunye ne-pulp yomthi, njl.) Imveliso ephumayo yi-derivative derivative ye-cellulose. Emva kwe-etherification, i-cellulose iyanyibilika emanzini, i-dilute isisombululo se-alkali kunye ne-organic solvent, kwaye ine-thermoplasticity. Kukho iintlobo ezininzi ze-cellulose ethers, ezisetyenziswa ngokubanzi kulwakhiwo, isamente, ipeyinti, amayeza, ukutya, i-petroleum, imichiza yemihla ngemihla, i-textile, i-papermaking kunye ne-electronic components kunye namanye amashishini. Ngokwenani lee-substituents, inokwahlulwa ibe yi-ether enye kunye ne-ether edibeneyo, kwaye ngokwe-ionization, inokwahlulwa ibe yi-ionic cellulose ether kunye ne-non-ionic cellulose ether. Okwangoku, iimveliso ze-ionic cellulose ether ionic zineteknoloji yemveliso evuthiweyo, ukulungiswa okulula, ixabiso eliphantsi, kunye nemiqobo ephantsi yoshishino. Zisetyenziswa ikakhulu kwizongezo zokutya, izinto ezincedisa i-textile, iikhemikhali zemihla ngemihla kunye namanye amasimi, kwaye zezona mveliso ziphambili kwimarike.
Okwangoku, ii-ethers ze-cellulose eziphambili kwihlabathiCMC, HPMC, MC, HEC, njl. Phakathi kwabo, i-CMC inemveliso enkulu, ibalwa malunga nesiqingatha semveliso yehlabathi, ngelixa i-HPMC kunye ne-MC i-akhawunti malunga ne-33% yemfuno yehlabathi, kwayeI-HECyenza malunga ne-50% yemfuno yehlabathi. I-13% yemarike. Eyona nto ibaluleke kakhulu ekupheleni kokusetyenziswa kwe-carboxymethyl cellulose (CMC) yi-detergent, ibalwa malunga ne-22% yemfuno yemarike esezantsi, kunye nezinye iimveliso zisetyenziswa kakhulu kwiindawo zokwakha, ukutya kunye namayeza.
Usetyenziso olusezantsi
Ngaphambili, ngenxa yophuhliso olulinganiselweyo lwemfuno yelizwe lam ye-cellulose ether kwimimandla yeekhemikhali zemihla ngemihla, amayeza, ukutya, iingubo, njl., imfuno ye-cellulose ether e-China yayigxininiswe kwintsimi yezinto zokwakha. Ukuza kuthi ga namhlanje, ishishini lezinto zokwakha lisathatha i-33% yemfuno ye-cellulose ether yelizwe lam. Imfuno yelizwe lam i-cellulose ether kwintsimi yezinto zokwakha iye yahlutha, kwaye imfuno kwimimandla yeekhemikhali zemihla ngemihla, amayeza, ukutya, iingubo, njl. Ngokomzekelo, kwiminyaka yakutshanje, i-capsules yemifuno ene-cellulose ether njengeyona nto iphambili ekrwada, kunye nenyama eyenziweyo, imveliso evelayo eyenziwe nge-cellulose ether, inethemba elibanzi lemfuno kunye negumbi lokukhula.
Ukuthatha intsimi yezinto zokwakha njengomzekelo, i-cellulose ether ineempawu ezibalaseleyo ezifana nokuqina, ukugcinwa kwamanzi, kunye nokunciphisa. Ngoko ke, i-ether yomgangatho wokwakha i-cellulose ether isetyenziswa ngokubanzi ekuphuculeni imveliso yodaka oluxubeneyo (kubandakanywa udaka olumanzi oluxubekileyo kunye nodaka oluxubekileyo), i-resin ye-PVC, njl. iimveliso zezinto zokwakha. Ndiyabulela kuphuculo lwenqanaba lelizwe lam lokuhlala ezidolophini, uphuhliso olukhawulezayo lweshishini lezinto zokwakha, ukuphuculwa okuqhubekayo kwenqanaba lomatshini wokwakha, kunye nokwanda kweemfuno zokhuseleko lokusingqongileyo kubathengi bezinto zokwakha kuqhubele phambili imfuno ye-non-ionic cellulose ethers. kwintsimi yezinto zokwakha. Ngexesha le-13 leSicwangciso seMinyaka emiHlanu, ilizwe lam lakhawulezisa inguqu kumatyotyombe asezidolophini kunye nezindlu ezidilikayo, laze laqinisa ulwakhiwo lweziseko ezingundoqo zasezidolophini, kuquka nokukhawulezisa inguqu yamatyotyombe axineneyo kunye neelali zasezidolophini, ngocwangco ukukhuthaza ukulungiswa okubanzi kweendawo zokuhlala ezindala; izindlu ezindala ezidilikayo kunye neeseti ezingagqitywanga Ukulungiswa kwezindlu kunye nokunye. Kwisiqingatha sokuqala sika-2021, indawo yezakhiwo zokuhlala ezisanda kuqaliswa kwizindlu zokuhlala yayiyi-755.15 yezigidi zeemitha zesikwere, ukwanda kwe-5.5%. Indawo egqityiweyo yokwakhiwa kwezindlu beziyi-364.81 million square metres, ukwanda ngama-25.7%. Ukubuyiselwa kwendawo egqityiweyo ye-real estate kuya kuqhuba imfuno ehambelanayo kwintsimi yezinto zokwakha i-cellulose ether.
Ipateni yokhuphiswano lwemarike
Ilizwe lam lelona livelisa i-cellulose ether ehlabathini. Ngeli nqanaba, izixhobo zokwakha zasekhaya ibakala le-cellulose ether liye lahlala kwindawo. I-Shandong Heda yinkampani ehamba phambili kwintsimi ye-cellulose ether e-China. Abanye abavelisi abakhulu basekhaya baquka iShandong Ruitai, iShandong Yiteng, kunye neNorth Tianpu Chemical, iYicheng Cellulose, njl. njl. Lotte. Ukongeza kwi-Shandong Heda kunye nezinye iinkampani ezinomthamo weetoni ezingaphezu kwe-10,000, baninzi abavelisi abancinci be-non-ionic cellulose ethers kunye nomthamo weetoni ze-1,000. Ukutya okuphezulu kunye neemveliso zebakala lamayeza.
Ukungenisa nokuthumela ngaphandle kwe-cellulose ether
Ngo-2020, ngenxa yokuhla kwamandla emveliso yeenkampani zangaphandle ngenxa yobhubhani waphesheya, umthamo wokuthumela ngaphandle kwe-cellulose ether kwilizwe lam ubonise ukukhula okukhawulezayo. Ngo-2020, ukuthunyelwa kwe-cellulose ether kuya kufikelela kwiitoni ezingama-77,272. Nangona umthamo wokuthumela ngaphandle welizwe lami-cellulose etherikhule ngokukhawuleza, iimveliso ezithunyelwa kumazwe angaphandle ikakhulu zizinto zokwakha i-cellulose ether, ngelixa umthamo wokuthumela ngaphandle weyeza kunye nebakala lokutya le-cellulose ether lincinci kakhulu, kwaye ixabiso elongezelelweyo leemveliso ezithunyelwa ngaphandle liphantsi. Okwangoku, umthamo wokuthumela ngaphandle we-ether yeselulosi yelizwe lam uliphinda kane umthamo wokungenisa, kodwa ixabiso lokuthumela ngaphandle lingaphantsi kabini ixabiso lokungenisa. Kwintsimi yeemveliso eziphezulu, inkqubo yokuthumela ngaphandle kwe-ether cellulose yasekhaya isenayo indawo eninzi yophuhliso.
