Zithini iipropathi zebhokisi ye-carboxymethyl seluplose, seluplose alkyl other, kunye neseluplose hydroxaylkyl other?

CI-Arboxymethyl Selelose:

I-Ionic Seleulose Ether yenziwa kwi-fibers yendalo (ikotoni, njl njl. Inqanaba lokufakwa endaweni yi-0.4 ~ 1.4, kwaye intsebenzo yayo ichaphazeleka kakhulu ngumgangatho wokufaka endaweni.

(1) Ibhokisi ye-carboxymethyl seluprose ye-hygroscopic, kwaye iya kuba namanzi amaninzi xa igcinwe phantsi kweemeko ngokubanzi.

. Xa iqondo lobushushu lingaphezulu kwe-50 ° C, i-viscosity ayinakuphikwa.

(3) Uzinzo lwayo luchaphazeleka kakhulu yiPH. Ngokubanzi, inokusetyenziswa ngodaka olusekwe kwiGyppum, kodwa hayi kudaka lwesamente. Xa i-alkaline kakhulu, iyakuphulukana noVikosity.

. Inefuthe lokubuyisa kwi-gyppum-esekwe ngodaka kwaye inciphise amandla ayo. Nangona kunjalo, ixabiso lebhokisi yebhokisi ye-carboxymethyl isezantsi kakhulu kune-methyl seluplose.

CI-Elllulose Alkyl Ether:

Abameleki yi-methyl sellise kunye ne-Ethyl Selelose. Kwimveliso yezamashishini, i-methyl chloride okanye i-ethyl chloride isetyenziswa njenge-arhente yokwamkelwa, kwaye impendulo yile ilandelayo:

Kwifomula, r imele i-CH3 okanye C2h5. I-Alkali Discation ayichaphazeli inqanaba le-etheriya, kodwa ikwachaphazela ukusetyenziswa kweendlela ze-alkyl halides. Ezantsi kakhulu iAlkali, eyomeleleyo ye-hydrolysis ye-alkyl halide. Ukwenzela ukunciphisa ukusetyenziswa kwearhente yokuthetha, uxinzelelo lwe-alkali kufuneka lonyuswe. Nangona kunjalo, xa ugxininiso lwe-alkali luphakamile kakhulu, isiphumo sokubila seselfowuni sincitshisiwe, esingayilungesi kwi-ethe terication ke ngoko kwancitshiswa. Ukulungiselela le njongo, i-zue egqwesileyo okanye i-ly eqinileyo iyongezwa ngexesha lokuphendula. Isalathiso kufuneka sivuselele isixhobo esihle kwaye siqhekeze ukuze ialkali ingasasazwa ngokulinganayo.

I-Methyl Selelose isetyenziswa ngokubanzi njenge-tickener, imbeke kunye ne-Cosloid njl njl. Ingasetyenziswa njengokusasazeka kwembewu, i-inki ye-piele, i-inki ye-pied, kwaye idityaniswe kwisamente esetyenzisiweyo ukulawula ixesha lokuseta kwaye yandisa amandla okuqala, njl.

Iimveliso zeSemyl Selelose zinamandla amakhulu oomatshini, bhetyebhetye, ukumelana nobushushu kunye nokungaxhathisi kubanda. I-Seluplose ethathiweyo ye-Sethyl inyibilikiswe emanzini nasekuhlambeni izisombululo, kunye neemveliso ezikwimigangatho ephezulu zinyibilikiswa kwizinyibilikisi eziphilayo. Ihambelana ngokuchanekileyo kunye ne-Persins eyahlukeneyo kunye neeplasitikisi. Ingasetyenziselwa ukwenza iiplastiki, iifilimu, ii-varnies, ii-adhesivers, i-latex kunye nezinto zokuzihlaziya amachiza, njl.

Ukuqaliswa kweqela le-hydroxalkyl ukuya kwi-Selsulose Alkyl Ewe kungaphucula amandla, ukunyusa ubushushu bezinto ezikhoyo kwezi ndawo zingasentla ziyahluka kunye nomyinge we-alkyl ukuya kumaqela e-hydroxayayl.

CElluplose hydroxaylkyl other:

Abameli baHydroxyylyl seluplopy kunye ne-hydroxypropyl seluplose Iiarhente eziqinisekisayo zii-epoxides ezifana ne-Ethylene oxide kwaye i-propleynene oxide. Sebenzisa i-acid okanye isiseko njengokukhulisa. Ukuveliswa kwezamashishini kukuphendula i-alkali Seleese nge-Arhente ye-ESKICATER: I-HYDROXCYTHTH LOLXOIT ngexabiso eliphezulu linyibilika kuwo omabini amanzi abandayo kunye namanzi ashushu. I-Hydroxypropyl seluplose enexabiso eliphezulu linyibilika kuphela emanzini abandayo kodwa hayi emanzini ashushu. I-HydroxyEtheetheetheetheetheetheethy inokusetyenziswa njenge-tickener yengubo ye-Latex, iPrintale yokuPrinta kunye ne-DEE yokuthintela i-DEE Ukusetyenziswa kwe-hydroxdproplol yeseluplose ifana neyo ye-hydroxyythl sellulose. I-HydroxyPOpyl seluplose enexabiso eliphantsi lokusetyenziswa linokusetyenziswa njengokungafuneki kwexesha elifanelekileyo, elinokuba nokubopha kunye nokubopha iipropathi.

I-carboxeymethylcelcelcelcelose, ifinyezwe njenge-CMC, ngokubanzi ikhona kwimo yetyuwa yesodium. Iarhente ye-ether i-monolothorocetic acid, kwaye impendulo yile ilandelayo:

I-Carboxymethyl Selelose yesona sifo seselula sinyibiliki. Kwixa elidlulileyo, yayisetyenziswa ikakhulu njengokuntywila kodaka, kodwa ngoku idluliselwe ukuba isetyenziswe njengesongezo, impahla yengubo ye-Carboxymethy Inokusetyenziswa kukutya, i-cosmetics, kunye nokubumba.

I-Polyanionic selsulose (i-PAC) yi-Ionic Seleclose i-ether kwaye yimveliso ePhakamileyo ye-carboxymethyl sellyulose (CMC). Yinto emhlophe, emhlophe-emhlophe okanye igranugule etyheli, engenatyhefu, engenabungozi, inyibilika ngokulula emanzini, inozinzo olubonakalayo kunye nozinzo oluthe kratya kunye nokuxhathisa ubushushu obuthile, kunye nepropathi yetyuwa. Akukho mbiza kunye nokuwohloka. Ineempawu zokucoceka okuphezulu, inqanaba eliphezulu lokufakwa endaweni, kunye nokusasazwa ngokutsha kweendawo ezingenayo. Ingasetyenziswa njenge-binder, i-tickener, i-Rheoology Sposho, ilahleko ye-FAID, isetyenziswa kakhulu, njl njl.

I-cyanoethyl seluplose yimveliso yokuphendula ye-sellulose kunye ne-acrylonitile phantsi kwe-ialkali:

I-cyanothyl seluplose inomgangatho ophakamileyo wokulala kunye nelahleko ephantsi ye-counted kwaye inokusetyenziswa njenge-phostrix ye-phospix ye-phospix kunye nezibane ze-elektroniki. I-clainothyl ye-cutanoethyl esezantsi inokusetyenziswa njengephepha lokufaka i-spericars.

I-EARECY KOSTY KOROOS, Alfeleyl

Iindlela zokulungiselela i-Telulose I-Ete Inokwahlulwa ibe yindlela ephakathi yamanzi, indlela yeSolvent, indlela yokuxovula, indlela yesilayidi, indlela yesigaba segesi, indlela yesigaba segesi kunye nokudityaniswa kwezi ndlela zingasentla.
