Ithini inkqubo yemveliso kunye noyilo lwe-sellulose ether?

I-SelerUlose Ether yi-polymer ye-polymer ye-polymer yesakhiwo esenziwe nge-sellyulose. I-Glucosyl nganye ye-Glucosyl kwi-selsulose iqukethe amaqela amathathu e-hydroxyl, iqela le-hydroxyl kwi-atom yesithandathu ye-carbon, i-hydroxy yeqela le-hydrocyl ithathelwa indawo ye-hydrocarbon yeqela lokwenza izinto.

Ukusetyenziswa kwe-selsulose ether

I-1

I-SeleseE-I-SelerUlose Ether yaziwa ngokuba yi "Freemied Monosodium Glutamate". Enkosi ngokugcinwa kwayo ngokungagungqiyo, ukugcinwa kwamanzi kunye nokubuyisa ipropathi, kusetyenziswa kakhulu ukuphucula nokwandisa udaka oluthe kratya, i-PVC Recince Peper, ipeyinti ye-PETEX, i-Petty Powder kunye nezinye izinto zokusebenza kwemveliso yokwakha. Enkosi ngokuphuculwa kwenqanaba lokufudukela kwelizwe lam, ukuphuculwa ngokukhawuleza kweshishini lokwakha, ukuphuculwa okuqhubekayo kwenqanaba lokukhula kwezendalo, kunye nokwanda kweemfuno zoKhuselo lweNkcubeko yezeNdawo kwi-Ionic ye-Ionic Seths.

I-Seleulsulose Teltulose isetyenziswe ngokubanzi kwimveliso yefilimu, imifula, iifilimu zamayeza, iiflimu, iicaphu zemifuno, iicaphu zemifuno, ezigciniweyo nezilawulwa kunye nezinye iindawo zamachiza. Njengemicimbi ye-skeleton, i-seluplose Ether inemisebenzi yokwandisa ixesha lokufumana iziyobisi nokukhuthaza ukusasazeka kweziyobisi kunye nokuchitheka; Njengekeyitha kunye nokudibana, kunokukuphepha ukonakaliswa nokunqunyulwa okunqamlezileyo kunye nokunyanga ukunyanga, kwaye sisixhobo esibalulekileyo sokuveliswa kwemveliso yamayeza. Itekhnoloji yesicelo yeBanga lase-Ethergulose I-Ether ivuthwa kumazwe aphuhlileyo.

I-3. IBakala lokutya ye-GEATE

I-Ibangane-Ibanga lesifo I-Ether i-Ether i-Ether kukhuseleko olukhuselekileyo lokutya. Ingasetyenziswa njengendawo yokutya, isitayile kunye nesifo se-suistrizer ukuba sikhule, sigcine amanzi, siphucule incasa. Isetyenziswe ngokubanzi kumazwe aphuhlileyo, ikakhulu kukubhaka ukutya okubhaka, i-collagen i-cream, ijusi yeziqhamo, iisosi, inyama kunye nezinye iimveliso zeprotein, ukutya okuthosiweyo, njl.

Inkqubo ye-Ether ye-Sele

1. Hydroxylyl methylcelcelcelose

Indlela yokulungiselela i-Hydroxyleleyl MethylcelceLcelose, le ndlela kukusebenzisa ikotoni ecocekileyo njengendawo engafunekiyo kunye ne-Ethylene oxide njenge-Arhente ye-ENGRONGEECTELOSE. Iinxalenye ezinobunzima bezixhobo eziluhlaza zokulungiselela i-Hydroxykyl Methyl Selelose zezi zilandelayo ze-typroxide, ezingama-80-85 ze-oxy-eshane, i-8-10-60 ye-methyl chloride, 16-19 iinxalenye ze-accetic acid; amanyathelo athile:

Inyathelo lokuqala, kwi-ketete ye-ketete, yongeza i-tolue kunye nomxube we-Isopropanol, kunye neSodium Hydroxide, ubushushu besiya kuthi ga kwi-60-80 ° C, qhubeka ufudumele imizuzu engama-20 ukuya kwengama-40;

Inqanaba lesibini, i-alkalition: pholisa le nto ingentla ukuya kwi-30-50 ° C, yongeza i-cotton ye-toluene, phuma i-Toopropanol Mxube, phumla i-itrogen ye-3, kwaye wenze i-alkali emva kokutshintsha. I-Alkali i-Alkalization, iimeko ze-alkalicys zezi: Ixesha le-alkalition yiyure ezi-2, ubushushu be-alkalic ngu-30 ℃ 50 ℃ 50 ℃;

Inyathelo lesithathu: Isivumelwano: Emva kokuba i-alkalization igqityiwe, i-reactor ikhutshwe kwi-0.05-0.07.07MPA, kunye ne-ithylene oxide kunye ne-methyl chloride yongezwa imizuzu engama-30-50; Inqanaba lokuqala lokuthengiswa: 40-60 ° C, 1.0-2.0 iiyure, uxinzelelo lulawulwa phakathi kwe-0.150.3.3.3. Inqanaba lesibini le-Etherheli: 60 ~ 90 ℃, 2.0 ~ iiyure eziyi-2.5, uxinzelelo lulawulwa phakathi kwe-0.40.8MPA;

Inqanaba lesine, ukungathathi cala: Yongeza i-acetic acetic acid, cinezela kwi-102 ° C yokuba kube yi-PHIPE Itanki yokuthintela i-deveolvenution igcwaliswa ngama-90 ~ I-100 ℃ I-Tap All All inyangwa sisixhobo se-osmos;

Inyathelo lesihlanu, ukuhlamba kwe-centrifugal: Izinto ezikwinqanaba lesine lifakwe kwi-Centrifuge ethembekileyo, kwaye izinto ezahluliweyo zitshintshelwe kwitanki yokuhlamba ephethwe ngamanzi ashushu ngaphambi kokuhlamba umxholo;

Inyathelo lesithandathu, i-Centrifugal yomisa: Izinto ezihlanjwe zidluliselwa kwi-certififul ye-screyitifu, kwaye loo nto yomiswa nge-150-16 ° C, kwaye izinto ezomileyo zityunyuzwe kwaye zipakishwe.

Xa kuthelekiswa neTekhnoloji ye-EERMUSE ye-OERUSEE, i-Inglone yangoku isebenzisa i-E-Inglone Axide njenge-Arhente yokulungiselela i-Hydroxyl Methyl Sellyl Guiling Amaqela e-hydroxyyl. Inozinzo oluhle lozinzo kunye nokuxhathisa i-therdew ngexesha lokugcina ixesha elide. Ingasetyenziswa endaweni yokunye iiselwase.
