Zithini iindidi ezahlukeneyo zeselpulose en efumaneka kwikhonkrithi?

I-Telupelose Ether sisiseko esibalulekileyo sokwakha esisetyenziswa ngokubanzi kwikhonkrithi kunye nodaka ukuphucula iipropathi zabo. Imisebenzi ephambili ye-Telulose Ether kwikhonkrithi ibandakanya ukuqina, ukugcinwa kwamanzi, ukulibazisa ukuseta, ukuphucula ukusebenza, njl.

1. I-Methyl Selelose (MC, Methyl Selelose)
I-methylcelculose yeyona ndlela ixhaphakileyo ye-ether ese seluplose, eveliswa ngokutshintsha amaqela e-hydroxyl kwi-seluplose kunye namaqela e-APLEGS (-och3). I-Methylcelsulose idlala indima yokutsalwa kunye nokugcinwa kwamanzi kwikhonkrithi. Ingayiphucula kakhulu ukunganyangeki kwekhonkrithi, yonyusa ubumbano lwekhonkrithi, ukunciphisa ukopha, ngaloo ndlela kuphucule ukusebenza kwekhonkrithi yokwakha kunye nokuqina kwekhonkrithi. Ukongeza, i-methylcelcelsulose ikwanazo iipropathi ezifanelekileyo zefilimu, ezinokuphucula ngokufanelekileyo ukugudla kunye nokufana komgangatho wekhonkrithi.

I-2. Hydroxypropyl methyl seluplose (hpmc, hpmroxypropyl methyl sethyl seluplose)
I-Hydroxypropyl Methylcelcelgalose iveliswa ngokwazisa ngakumbi i-hydroxypropyl (-C2chohch3) kwisiseko se-methylceltulose. I-HPMC inezinto ezingcono zokugcinwa kwamanzi kunye neepropathi ezinkulu, ngoko ke zibonisa uzinzo ezinamandla kunye ne-anti-SAG kwikhonkrithi yekhonkrithi. Ingagcina intsebenzo elungileyo yokugcina amanzi kumaqondo obushushu aphezulu kwaye kuthintele amanzi kwikhonkrithi ekukhupheleni okuphuma ngokukhawuleza, ngaloo ndlela kuncitshiswa ukwenzeka kweendawo zokuhlala. Ukongeza, i-HPMC inokulibazisa ukukhawulezisa isantya se-qumedym hydration, ivumela ikhonkrithi ukuba isebenze ixesha elide kwaye iququzelele ulwakhiwo.

I-3. Hydroxykyl seluplose (hec, hydroxyythy seluplose)
I-HydroxyEtheetheetheetheethy iveliswa ngokwazisa amaqela e-hydroxythyl (-C2C2C2oh) kwiimolekyuli. Umsebenzi ophambili we-hec kwikhonkrithi kukuphucula kwaye uphucule iipropathi zekhonkrithi zekhonkrithi. Xa kuthelekiswa nezinye i-Selese, i-HC iZinzile kakhulu phantsi kweemeko ze-Alkaline, ngoko ke isetyenziswa ngokubanzi kwikhonkrithi. Ingaphucula ukusebenza kwe-anti-SAG yekhonkrithi kwaye yonyuse amandla aphezulu ekhonkrithi. Ingakumbi kwikhonkrithi exutywe elungele efuna ukuba isigcini sexesha elide okanye i-hec, i-HEC inokuthintela ngokufanelekileyo ukulibazisa nokopha.

4. I-HYDROXPOPLL LELULOse (HPC, Hydroxdpropy)
I-Hydroxypropyl iseluplose iveliswa ngokwazisa iQela le-hydroxypropy ye-hydropyl Ifana ne-HPMC, i-HPC ikwanazo neepropathi ezihle kakhulu nezamanzi. Ukongeza, i-HPC ikwanokufumana izibonelelo ezifanelekileyo ze-therm kunye nefilimu, ezinokuphucula ukunganyangeki kwe-rack kunye nokuqina kwekhonkrithi. Phantsi kweemeko zobushushu obuphezulu, i-HPC inokunciphisa kakhulu ukukhutshwa kwamanzi kwikhonkrithi, ngaloo ndlela kuthintela ikhonkrithi.

I-5. Hydroxyl methyl seluplose (hemc, hydroxyythy methyl sethyl seluplose)
I-HydroxyEthythylcelcelcelcelose iveliswa ngokwazisa amaqela e-hydrokyteythyl kwi-methylceluplose. I-HMC idibanisa iimpawu ze-HeC kunye ne-MC, ineepropathi ezintle kwaye inakho ukuphucula ukusebenza kunye nokuqina kwekhonkrithi. Isetyenziswe ngokubanzi kwikhonkrithi, ngakumbi ekuziqokeleleni isigulo somlinganiso kunye nodaka lobushushu. I-HMC inokuphucula ukusebenza ngokuphumelelayo ukusebenza, ukunciphisa ilahleko yokufuma kodaka, kwaye kuthintele imifuno emva komomo.

I-6. I-Ethym seluplose (EC, Ethyl Selelose)
I-Ethylcellulose iveliswa ngokutshintsha amaqela e-hydroxyl kwimolekyuli eselselose eneqela le-ethoxy (-oc2h5). I-EC ayifane isetyenziswe kwikhonkrithi, kodwa idlala indima ebalulekileyo kwikhonkrithi ekhethekileyo efana nekhonkrithi ephezulu yekhonkrithi. I-EC ineepropathi ezintle kwaye zibonisa iipropathi kwaye zinokuphucula amandla kunye nokunganyangeki kwekhonkrithi. Ukongeza, i-EC ikwanokuchaswa kakuhle kunye nokuzinza kobushushu, ukuze isetyenziswe ngokufanelekileyo kwezinye iindawo ezikhethekileyo.

7. Methyl Hydroxyythyl seluplose (MHC, Methyl Hydroxyythyl seluplosethy
I-Methyl HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheetheetheethl idibanisa iimpawu ze-MC kunye ne-hec kwaye inesithukuthezi esihle, ukugcinwa kwamanzi kunye nokugcina amanzi. Indima ephambili ye-MHEC kwikhonkrithi kukuphucula iipropathi eziqhutywa kunye nokunganyangeki kwekhonkrithi. Yeyona nto isetyenziswa ngokubanzi kwikhonkrithi yekhonkrithi kunye nokulungisa ukufa.

I-Seleulose Teltulose Telwely isetyenziswe ngokubanzi kwikhonkrithi kwaye ineentlobo ezahlukeneyo. Iindidi ezahlukeneyo zeSeluplose e-Seles zineziseko ezahlukeneyo zekhemikhali kunye neepropathi zomzimba kwaye zinokuhlangabezana neemfuno zeeprojekthi ezahlukeneyo. Ukukhetha uhlobo lwe-ether ye-Elessulose ekunene kunokuphucula kakhulu ukusebenza, amandla kunye nokuqina kwekhonkrithi, ngaloo ndlela kunyusa umgangatho kunye nokuthembeka kweeprojekthi zokwakha. Kwizicelo ezisebenzayo, kufuneka ukhethe ngokufanelekileyo uhlobo kunye nedosi ye-seluplose i-ether ngokusekwe kwiimfuno zoNqununu zeNjineli kunye neemeko zokwakha ukufezekisa ezona ziphumo zisetyenziswayo.
