Ukuvula i-cotton-father-i-althering-ukwahlula-hlula-ukwahlula-hlula-hlula, ukuvula-ukusoma-ukupakisha i-cotton ekupakisheni: Ikotoni ecocekileyo ivuliwe ukususa i-iron, emva koko ikhutshelwe. Ikotoni ecocekileyo ikwimo yepowder ikwimo yomgubo, kwaye ubungakanani bayo buyi-80 Mesh kunye ne-Districtation yi-100%. Ngaphandle koko, kulula ukuphatha kunye ngexesha lokuphendula kunye nokunciphisa ukusebenza kakuhle kowaso.
I-Alkalization: Yongeza i-cotton ye-powded emva kokuvula i-intert ye-intert, kwaye isebenze nge-Alkali kunye ne-Alkali kunye ne-Alkali kunye ne-Internation ye-cottiment ye-estion, kwaye iphucula ukufana kwe-etherming yokuphendula. I-alkali esetyenziswa kwi-alkalization yi-hydroxide yensimbi okanye isiseko sezinto eziphilayo. Isixa se-alkali esongeziweyo (ngobunzima, esingezantsi) sisi-0.1-0.6 amaxesha ekotoni ecocekileyo, kunye nenani lamanzi athambileyo yi-cotton yomqhaphu; I-Inert ye-Instevent ngumxube wotywala kunye ne-hydrocarbon, kunye nenani le-intert ye-Inict yongezwa yikotoni ecocekileyo. Amaxesha angama-7 ukuya kweli-15: I-Inert ye-InEtven inakho ukuba yi-aton ye-carbon ene-Atoni (efana notywala, i-propanol), i-acetone. Ingakwazi ukuba nee-hydrocarbons ze-hydrocarbons kunye neebhulukhwe ze-hydrocarbons; amaqondo obushushu kufuneka alawulwe ngaphakathi kwe-0-35 ° C ngexesha lokuphulukana; Ixesha le-alkali imalunga ne-1hr. Uhlengahlengiso lobushushu kunye nexesha lungagqitywa ngokweemfuno zezinto ezibonakalayo kunye nemveliso.
Isiqinisekiso: Emva konyango lwe-alkalition, phantsi kweemeko ze-vacuum, i-ethe therhemu yenziwa ngokongeza iarhente eyaziwayo, kwaye iarhente ye-estide i-proplene oxide. Ukwenzela ukunciphisa ukusetyenziswa kwearhente yokuthetha, kwinkqubo yokuthengisa, iarhente ye-E-EUREAT idityanisiwe ngamaxesha amabini, kunye nenani longezelelo lwe-1-3.5. amaxesha. Emva kokongeza iarhente yokuthetha okokuqala, ivuse kwiqondo lokushisa le-≤ 30 ° C ukuya kwi-45min-90min, i-Shormaider ukuya kwi-1 ukuya kwi-5 yexesha, kwaye emva koko ifudumeza? ? ? Yenza i-ether, ixesha yi-1-4h, ngeli xesha, i-cotton yecotton kunye nearhente yokuphucula i-esser iphendule ngokupheleleyo ukuvelisa i-H-HPC.
Ukucofa kunye nokupakisha: imveliso eyomileyo yendawo yokuyilwa yangoku ikhutshelwa kwaye ihleliwe. Ubungakanani bentsalela yemveliso etyhidiweyo kunye ne-Direen of the and i-40 mesh kunye ne-Deritrating yi-10096, okanye ngokokudinga umsebenzisi. Emva koko ukupakishe ngaphandle komzi-mveliso.
Ixesha leposi: NgoFebwe-20 ukuya ku-525
