1. Indlela yokuphelisa i-Ethyy Selelose
I-Ethyl Selelose (EC) yikhemikhali eyenziweyo nge-sellylase yendalo, enee-biomatiwes ilungileyo, enganetyhefu kunye nokuhlanjwa. Kuba isakhiwo sayo sinenani elikhulu le-hydroxyl kunye namaqela e-ethyl, inomngeni othile wokunyibilikisa. Ukwenzela ukunyibilikisa i-seluplose ye-sellyulose, iindlela ezithile zokuchitha kunye nezitoli zihlala zifuneka.
Ukukhethwa kweSolvent
I-solity ye-ethyl sellulose ixhomekeke kubunzima bemolekyuli, isidanga se-ithemy kunye nesinyibilikisi esikhethiweyo. Ngenxa yeempawu zesakhiwo se-Ethyy Selelose, ngokubanzi ingena emanzini, kodwa inokuchithwa kwiintlobo ezahlukeneyo zezinyibilikisi eziphilayo. Izinto eziqhelekileyo ezisetyenzisiweyo zibandakanya:
Izinyibilikisi zotywala: ezinje nge-ethanol, i-Iyopropanol, i-N-Propanol, njl. Njl.
I-ether izinyibilikisi: ezinje nge-dimthyl sulfoxide (DMSO), i-chloroform, njl njl.
I-Ketones isuti: njengeacetone, njl.
Izinyibilikiswa eziphisweyo: ezinjenge-chloroform, i-carbon tetrachloride, njl njl.
Amanyathelo okunyithi
Amanyathelo aphulukene ne-Sethyl Selelose ngokubanzi ngolu hlobo lulandelayo:
Ukuchithwa kwangaphambili: Yongeza ngononophelo se-Sethyl sellulose kwi-Solvent ekhethiweyo, qinisekisa ukuba isixa se-solvent sanele ukugubungela ise sethyl sethyl, kwaye ngobushushu begumbi ukuze siyincede sisasaze ngokulinganayo.
Ukufudumeza: Ukuba kunzima ukunyibilikisa kubushushu begumbi, iqondo lobushushu linokunyuka ngokufanelekileyo (lingabi ngaphezu kwama-70 ° C) kwaye ifudumele inyibilikisile ukwenza i-sthyl secelose kunokuba lula ukuyinyibilika.
Ukudinwa: Emva kokupheliswa kugqityiwe, ukuba kukho amaqabungo kwi-solvent, amaqabu avumelekile ukuba abaleke ngokunciphisa uxinzelelo okanye ukuma ixesha lokuqinisekisa uzinzo kunye nokufana kwesisombululo sokugqibela.
Ukuthatha amanyathelo ngexesha lokupheliswa
Ulawulo loxinzelelo: Eyona phenyane ye-Ethyl Sethyl Selelose inokubangela ubunzima. Kuyacetyiswa ukuba uhlengahlengise i-smobibance njengoko kufuneka.
Ukukhethwa kweSolvent: Iimodeli ze-Sethyl ze-Sethyl Selelse (ezinje ngemilinganiselo yemolekyuli eyahlukileyo, idigri eyahlukeneyo yokulungisa) ineemfuno ezahlukeneyo zokuzithoba. Ukukhetha isisweli esifanelekileyo kunceda ekuphuculeni ukusebenza ngempumelelo.
2. Ukusetyenziswa okuphambili kweSellyulose
I-Ethyy Seluplose isetyenziswa ngokubanzi kumasimi amaninzi ngenxa yeepropathi zayo ezibalaseleyo zomzimba kunye neekhemikhali (ezinjengokungasebenzi, uzinzo lwefilimu, uzinzo, njl njl). Nazi ezinye zezinto eziphambili:
I-Carried Contrimed Commer
I-Ethyl Selelose ine-bimoMPise elungileyo kunye nokungasebenzi, kwaye ihlala isetyenziswa njengearhente yokukhutshwa kweziyobisi okanye iarhente yokukhupha i-arhente. Inokuphucula ukusebenza ngempumelelo kweziyobisi kwaye inciphise iziphumo ebezingalindelekanga ngokulawula isantya kunye nexesha lokukhululwa kweziyobisi. Izicelo eziqhelekileyo zibandakanya amachiza omlomo, iipakethi ze-transbal, njl.
I-Coasthings kunye ne-membrane zixhobo
I-Ethyy Seluplose inepropathi ebalaseleyo yefilimu kunye namandla omatshini, ngoko ke isetyenziswa ngokubanzi ekutyeni nasekuhlawuleni amachiza. Inokwenza umaleko ocekeceke kwaye ungenise i-wilimu ukukhusela izinto zangaphakathi kwindalo yangaphandle kwaye unyuse uzinzo nobomi bemveliso yemveliso. Izicelo eziqhelekileyo zokudibana zibandakanya ukuqeshwa kweswekile, ukurhweba ngamachiza, njl.
Ishishini lokutya
Kwishishini lokutya, i-sethyl sethylse isetyenziswe ngokubanzi njengesongezo lokutya. Ingasetyenziswa njenge-thi checker, i-sticker, i-mulsifier, njl njl. Ukuphucula ukuthungwa kunye nokuncancisa ukutya. Umzekelo, i-Ethyl Selelose inokusetyenziswa njengendawo yokutya okuphantsi kakhulu ukunceda ukulawula umxholo wamanqatha kunye neswekile.
Ishishini le-cosmetics
Kwi-cosmetics, i-sthyl secelose ihlala isetyenziswa njenge-thi chulener, i-emulsifier kunye nefilimu yangaphambili, enokuphucula ukungqinelana, uzinzo kunye nokuchukumisa i-emulsion xa isetyenziswa. Umzekelo, iselkhel sethyl selselose inokufumaneka kwiimveliso ezinjengeekhrims zobuso, ii-condioners kunye neelephu.
Iphepha kunye nokwenza i-leleil
Njengokukhupha i-seluplose yendalo, i-sthyl secelose idlala indima ebalulekileyo ekuqhubeni iphepha kunye nee-tics. Inokonyusa amandla ephepha, ukuphucula umgangatho womhlaba, kunye nokuphucula ukumelana nebala kunye nokuchasana kwamabala.
Iingubo kunye neepeyinti
Njengefilimu eyayisakuba yingubo yangaphantsi, iseti se-Sellyl Selese iseyinto esetyenziswayo kwimveliso yeepeyinti kunye neengubo. Ingaphucula ukuqina, uzinzo kunye nobiyelelo lwekhreyithi, ngelixa iyonyusa i-gloss yokuhamba.
Izixhobo ezinobuhlobo kwindalo
Ngenxa yokuhlaselwa kwayo kunye netyhefu esezantsi, i-sellyl secelose ikwafundisiwe kuphuhliso lwezinto ezinobuhlobo bokusingqongileyo. Umzekelo, kumacandelo onyango lwamanzi kunye nokuphuculwa komhlaba, iimpawu zokukhusela okusingqongileyo ze-Ethyl SellUlose zenza ukuba kube yinto eluhlaza enokubakho.
Njengezinto ezibalulekileyo zekhemikhali, i-sthyl secelose idlala indima ebalulekileyo kumashishini amaninzi. Indlela yayo yokugqabhuka ikakhulu ixhomekeke ekukhetheni izinyibilikisi eziphilayo, kunye nezinyibilikisi eziqhelekileyo zibandakanya ilokishi, oonina, naseKetones. Ngokutsho kokusetyenziswa okwahlukileyo, i-sethyl sethyl sethyl isenokusetyenziswa ngokubanzi kukhululo olulawulwa ngamachiza, ishishini lokutya, ukuvelisa izinto zokutya, ukuvelisa amayeza, kwaye kunesidima esihle sendalo kunye nobuhlobo bokusingqongileyo. Ngeemfuno ezandayo zezinto eziluhlaza nezisingqongileyo ezinobuhlobo, amathuba esicelo seselokose abanzi kakhulu.
