Ulwazi oluyinyani

I-Hydroxypropyl Methylcelcelsele (i-HPMC) yi-ionic ye-ionic sether ye-iether eyenziwe kwi-polymer yendalo ye-polymer ngothotho lweenkqubo zekhemikhali. Ziyi-odortives, engenakuthelekiswa nanto kwaye ingenatyhefu emhlophe eshukumayo kwisisombululo esicacileyo okanye esincinci esincinci emanzini abandayo. Ibiyele, ibophelelekile, isasaza, ukonakalisa, ukwenza ifilimu, ukumisa ifilimu, ukumiswa, ukulungisa, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid esebenzayo, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid esebenzayo, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid, ukugcinwa kwe-colloid esebenzayo, ukugcinwa kwe-colloid esebenzayo. I-HydroxyPOpyl Methyl Sellulose neMethyl Selelose inokusetyenziswa kwizinto zokwakha, ishishini lokupeyinta, i-resin yepeyinti, ishishini, ukutya, ezolimo, amanye amachiza emihlathi.

Iziphumo zokugcina amanzi kunye nomgaqo-siseko we-hydroxypropyl methylcelcelcelse hpmc

I-seluplose ether hpmc ikakhulu idlala indima yokugcinwa kwamanzi kunye nokutyibilika kwisamente yesamente i-cering kunye ne-fypsim esele i-Gypsim kunye nokuchasana ne-SEGRY.

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 weemveliso ezinomgangatho ofanayo we-HPMC yongezwa. 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 ezibalaseleyo ze-HPMC zinokusombulula ngokufanelekileyo ingxaki yokugcina amanzi phantsi kobushushu obuphezulu. 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, ukuze alawule ngokukuko kwamanzi okubangelwa bubushushu obunobushushu obuphezulu, kwaye afezekise ukugcinwa kwamanzi.

I-HETMPMEX ENTME STOPMC inokuba yinto efanayo kwaye ichithwe ngokufanelekileyo kwi-Creating Cetimes Andstor, kwaye i-Inorgamu ikhutshwe ngokuthe ngcembe, kwaye i-Inorganic Geation iqinisekise ukuba amandla ebhondini aya kuqinisekisa amandla ebhondini kwaye aqinisekise ukomelela kwe-bod. Ke ngoko, kulwakhiwo oluphezulu lokwakhiwa kweqondo lobushushu, ukuze kufezekiswe imisebenzi yokugcina amanzi, kunyanzelekile ukuba bongeze iimveliso ezikumgangatho we-HPMC kwi-FOTURAS ngokwefom yefomula, kungenjalo, ukuncitshiswa komgangatho, ukuqhekeza, ukungcungcutheka okubangelwa kukomile kakhulu. Iingxaki, kodwa ukwandisa ubunzima bokwakha abasebenzi. Njengoko iqondo lobushushu lihla, inani lamanzi e-HPMC longezwe linokuncitshiswa ngokuthe ngcembe, kwaye kuya kufezekiswa.

Ukugcinwa kwamanzi kwi-hydroxypropyl methylcelcelsulose yemveliso ye-HPMC ngokwayo ihlala ichaphazeleka kwezi zinto zilandelayo:

I-1. Ukufana kwe-seluplose ether hpmc

Ngokucacileyo i-HPMC, i-MacxGyl kunye ne-hydroxypropoxyl zisasazwe ngokulinganayo, kwaye inqanaba lokugcina amanzi liphezulu.

I-2. I-Telupelose Ether HPMC yeqondo lokushisa i-gel

Ukuphakama kweqondo lobushushu be-thermal, ukuphakamisa inqanaba lokugcina amanzi; Ngaphandle koko, iphantsi inqanaba lokugcina amanzi.

I-3. I-Telupelose Ether HPMC Viscofity

Xa i-vickosity ye-HPMC inyuka, iqondo lokugcina amanzi liyanda; Xa i-viscosity ifikelela kwinqanaba elithile, ukwanda kwemilinganiselo yokugcina amanzi ethambile.

4. Isixa semali yesellulose 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 linyusa ngokukhawuleza ngokunyuka kwenani elongeziweyo; Xa ukongezwa konyuso lonyuka, ukunyusa imeko yeqondo lokugcina amanzi liyacothisa.
