I-HydroxyPOpyl Methyl Selelise HPMC yi-Ionic se-ionic sether sether eyenziwe kwi-polymer yendalo ye-polymer ngoluhlu lwemichiza. Ziyi-odortives, engenakuthelekiswa nanto kwaye ayinatyhefu emhlophe eshukumayo kwi-colloidal yesisombululo esicacileyo okanye esincinci emanzini abandayo. Ineempawu zokutyibilika, ukusasaza, ukusasazwa, ukwakhiwa, ukwenziwa kwefilimu, ukumiswa, i-adsorvotion, umsebenzi wokuthambisa, umphezulu we-colloid kunye nokukhusela i-colloid. I-HydroxyPOpyl Methylcelceltulose inokusetyenziswa kwizinto zokwakha, ishishini lokutshona kwe-windows, ishishini le-ceramic, i-ceramic, ishishini, impahla yezolimo, amanye amakhamisi, amanye amakhamamikhali kunye namanye amakhamisi.
Umsebenzi wokugcinwa kwamanzi kunye nomgaqo: I-Seleulose Ether HPMC ikakhulu idlala indima yokugcinwa kwamanzi kunye nokuhlelwa kwamanzi e-Cetican kunye ne-Gypsim esekwe yi-furry kunye nokuchasana ne-SUGRY. Izinto ezifana neqondo lobushushu lomoya, ubushushu kunye nesantya somoya esinesantya somoya siya kuchaphazela ireyithi yamanzi esinqeni sesamente Ke ngoko, kumaxesha ahlukeneyo, kukho umahluko kumsebenzi wokugcinwa kwamanzi wexabiso elilinganayo leemveliso ze-HPMC. Kumsebenzi othile, umphumo wokugcinwa kwamanzi okutyibilika unokwanda ngokwanda okanye ukwehla kwe-HPMC yongezwa.
Ukugcinwa kwamanzi kwe-Methyl Seler I-Ether phantsi kweemeko zobushushu obuphezulu kubalulekile ukwahlula umgangatho we-methyl seteli. Iimveliso ezigqwesileyo ze-HPMC ze-HPMC zinokusombulula ngokufanelekileyo ingxaki yokugcinwa kwamanzi kumaqondo obushushu aphezulu. Kumaxesha obushushu aphezulu, ngakumbi kwiindawo ezishushu nezomileyo kunye nolwakhiwo olucekeceke kunye ne-HET-DEARE
I-HPMC esem nangaphezulu ye-HPMC inento entle kakhulu. Indlela yayo ye-hydroxypropospy ihanjiswa ngokulinganayo kwi-selseul ye-folecular, enokuphucula amandla eeathom zeoksijini kwi-hydroxyl kunye ne-ether Binds ukuba idibanise namanzi ukwenza i-hydrogen hands. , Ukuze amanzi asimahla abe ngamanzi adityanisiweyo, ngaloo ndlela ukulawula ukukhutshwa kwamanzi okubangelwa bubushushu obungaphantsi kwemozulu, kunye nokufezekisa ukugcinwa kwamanzi.
I-HETMPME-EKITMS ELPMC inokuthi ilingane kwaye ichithwe kakuhle kwi-CETATIONS ECANDELEKILEYO NOBUCHULE BOKUGQIBELA Amanzi esiseko akhutshwa ngokuthe ngcembe ixesha elide. Izinto ezincitshisiweyo zisabela ngokusabela, ukuze kuqinisekiswe amandla e-bondile kunye namandla engcinezelo yezinto. Ke ngoko, kulwakhiwo oluphezulu lokwakha, ukuze kufezekiswe iziphumo zokugcina amanzi, iimveliso ezikumgangatho ophezulu ze-HPMC kufuneka zongezwe ngamanani aneleyo ngokwefomula, kungenjalo, ukunciphisa amandla, ukuqhekeza, ukuwela iya kwenzeka ngenxa yokomisa kakhulu. Iingxaki, kodwa ukwandisa ubunzima kwabasebenzi bokwakha. Njengoko iqondo lobushushu liyancipha, isixa se-HPMC songezwe sinokuncitshiswa ngokuthe ngcembe, kwaye indlela yokugcina amanzi efanayo inokufezekiswa.
Ukugcinwa kwamanzi kwe-HPMC kuchaphazeleka kwezi zinto zilandelayo:
1
Kwi-HPMC eyayisenziwa nge-HPMC, i-Mazantsi kunye ne-hydroxypropospy yamaqela ahanjiswa ngokulinganayo, kwaye inqanaba lokugcina amanzi liphezulu.
I-2. Iqondo lokushisa i-germal ye-sellulose ether hpmc
Amaqondo obushushu e-thermal iphakamile, inqanaba lokugcina amanzi liphezulu; Ngokuchasene noko, inqanaba lokugcina amanzi liphantsi.
I-3. I-Viscosity ye-Selese-I-EREMC
Xa i-vickosity ye-HPMC inyuka, iqondo lokugcina amanzi liyanda; Xa i-viscosity ifikelela kwinqanaba elithile, ukwanda kwiphepha lokugcina amanzi lithanda ukuba lifihla.
4. Ukongezwa kwe-selselese ether hpmc
Inqanaba elikhulu le-iler i-erlulose i-HPMC yongezwa, iphakamile kwinqanaba lokugcina amanzi kunye nokulungileyo komsebenzi wokugcinwa kwamanzi. Kuluhlu lwe-0.25-0.6% eyongezwayo, izinga lokugcina amanzi liyanda ngokukhawuleza ngokunyuka kwenani elongeziweyo; Xa ukongezwa konyuso lonyuka, ukunyuka kwenqanaba lokugcina amanzi kuyacotha.
IXESHA LOKUQALA: I-DEX-16 ukuya ku-2001
