Ukuqaliswa ngokutsha kwe-selsulose ether

I-selsulose ether i-seluplose yendalo (i-cotton ye-pulko ye-pulthi, njl. Njl. I-seluplose inokuchithwa emanzini, i-dilute i-alkali i-solkali kunye nesinyibilikisi se-organic emva konyamezelo, kwaye ineempawu ze-thermoplastic. Iintlobo ngeentlobo ze-seluplose, ezisetyenziswa ngokubanzi ekwakhiweni, ukuqhuba, amayeza, ipetroleum, iikhemikhali zemihla ngemihla kunye namanye amashishini. Ngokwenani lezinye elinokwahlulwa endaweni ye-ether enye kwaye ixutywe ne-ether exutywe, ngokutsho kwe-ionsus inokwahlulwa kwi-Ionic Selersulose Ether i-Ether I-Ether Sethelise. Okwangoku, i-ionic seluplose i-ethe ye-Ionic imveliso iqolileyo ivuthiwe, kulula ukwenza kwaye ixabiseke kakhulu, isetyenziswa kakhulu kwizongezo zokutya, iikhemisi zendawo, zezona mveliso ziphambili kwintengiso.

Okwangoku, i-Wortustream yeHlabathi yeHlabathi yi-ERC, i-HPMC, i-MC, i-HEM kunye ne-Akhawunti ye-Akhawunti ye-33 ye-Akhawunti ye-Akhawunti ye-Global, i-HMC imalunga ne-13% yentengiso yehlabathi. Esona siphelo sibalulekileyo se-carboxymethyl seluplose (CMC) sisicoci, sinika ingxelo malunga neepesenti ezingama-22 zeemfuno zentengiso esezantsi, kunye nezinye iimveliso zisetyenziswa ikakhulu kwizinto zokwakha, ukutya kunye namayeza.

II. Isicelo se-Dowystream

Kwixa elidlulileyo, ngenxa yophuhliso lwemfuno encinci ye-seluplose kwiikhemikhali zemihla ngemihla, amayeza, ukutya, ishishini le-Cleculose eTshayina, ishishini lokwakha i-e Caluplose e Caluplose Ether e Caluplose e-Iteli. Kwaye njenge-CalUlose Ether I-Ersulose Ether kwicandelo le-china lezinto zokwakha ligcwele, kwiikhemikhali zemihla ngemihla, amayeza, ukutya, ukuthuka kunye nezinye iinkalo zemfuno zikhula ngokukhawuleza ngokuphuhliswa kwetekhnoloji yesicelo. Umzekelo, kwiminyaka yakutshanje, i-capsule yesityalo ephethe i-selsulose ether njengeyona nto iphambili, kunye neemveliso ezivelayo ezenziwe ngenyama yokufakelwa kunye ne-Ether I-Ether Amathemba aBanzi kunye nendawo yokukhula.

Kwicandelo lezinto zokwakha, umzekelo, i-seluplose i-ethe-therfung, ukugcinwa kwamanzi, ipeyinti ehamba kancinci, ipeyinti edibeneyo, i-Pelex, i-Pelex, i-Enter .... .. Umzi mveliso, inqanaba lokwakha indlela yokwakha liyaqhubeka, kwaye iimfuno zokusingamela kwezendalo ezizezona zinto zibonakalayo ziya zingaphezulu nangaphezulu, zikhokelela kwimfuno ye-ionic ye-ionic seric. Ngexesha leSicwangciso seminyaka emi-13, i-China yakhawulezisa ukulungiswa kweendawo ezirhabaxa kunye nezindlu ezixineneyo kwizixeko, kwaye zomeleze ukwakhiwa kwezindlu ezihamba ezidolophini kunye nokuhlaziywa kwezindlu ezixineneyo kunye neeseti ezingekho mthethweni kunye neeseti ezingezozadima. Kwisiqingatha sokuqala se-2021, 755.15 yezigidi zeemitha zendawo yokuhlala yaqalwa, ipesenti i-5.5 pesenti. Indawo egqityiweyo yezindlu ingama-364.81 yezigidi iimitha ezingama-25,7%. Indawo yokuphinda ibuyiselwe kwindawo yendawo yokuhlala iya kuqhuba ibango elifanelekileyo kwicandelo lezinto zokwakha i-selselose.

I-3. Ipateni yokhuphiswano lwentengiso

I-China liyindawo ye-Ether ye-Ether ye-Ether ye-Elersulose, kwinqanaba langoku lezixhobo zokwakha i-Ether ikwanokubandakanya amashishini aseSelew, i-Ashland i-Ethew okwangoku i-Eumaties i-EURE YENKULUMKO, EMISELWEYO SHINETSU, EMZANTSI ZE-MORTATE NOLWAZI I-Monopoly. Ukwengeza kwiI-Casin chemistryAmaqela angaphezu kwamawaka alishumi amashishini, amawaka eetoni ze-ionic selsulose e-Ioser amashishini amancinci emveliso, kwaye akukho mandla okuvelisa ukutya okuphezulu kwe-ETER kunye neemveliso zamachiza amayeza.

Ezine, iseti ye-ether yokungenisa kunye nemeko yokuthumela kwelinye ilizwe

Ngo-2020, ngenxa yokuBekina waphesheya kukhokelela ekwenzeni ukwehla kwamashishini angaphandle 'kwimveliso ye-Chinase e-Ether babonisa indlela yokukhula ngokukhawuleza, ngonyaka. Nangona ivolumu yokuthumela kwelinye ilizwe i-selsulose e-Calulose e-China ikhula ngokukhawuleza, iimveliso zokuthumela ngaphandle zisekwe ikakhulu kwiSublulose Ether, ngelixa i-ether yokuthengisa i-Ether kunye nexabiso longeziweyo kwiimveliso zokuthumela ngaphandle ziphantsi. Okwangoku, ivolumu yokuthumela i-Teluplose Ether e-China iphindaphindwe kane ivolumu, kodwa ivolumu yokuthumela ngaphandle ingaphantsi kwamaxesha amabini. Kwicandelo leemveliso ezikufutshane seSelsulose yaseKhaya kwi-Other yokuthumela ngaphandle kwe-Other isesisithuba esikhulu sophuhliso.
