I-Hydroxypropyl Methyl Selelise (HPMC) kunye noMgaqo-nkqubo wokuGcina amanzi!

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-HOTMEX ENTMC inokuthi ilingane kwaye ichithwe ngokufanelekileyo kwi-CETATE DETATIONS ENYE, NOKUGQIBELA Ukuphendula okungenamkhethe kwemixholo ebekiweyo kuya kuqinisekisa amandla ebhondi kunye namandla engcinezelo yezinto. Ke ngoko, kulwakhiwo oluphezulu lokwakha ihlobo, ukuze kufezekiswe imisebenzi yokugcina amanzi, kunyanzelekile ukuba bongeze iimveliso ezikumgangatho we-HPMCs ezikwi-HPMC kwifom yefomula ngokwefom, kungenjalo, ukuncitshiswa kwamandla, ukuqhekeka kunye nokuqhekeka 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-HPMC ethi i-HPMC, i-Macxyl kunye ne-hydroxypropoxyl zisasazwa ngokulinganayo, kwaye inqanaba lokugcina amanzi liphezulu;

I-seluplose ether hpmc i-helrmal ye-gel iphezulu, inqanaba lokugcina amanzi liphezulu; Ngaphandle koko, inqanaba lokugcina amanzi liphantsi;

Xa i-viscosity ye-seluplose ether HETMC inyuka, iqondo lokugcina amanzi liyanda; Xa i-viscosity ifikelela kwinqanaba elithile, ukwanda kwemilinganiselo yokugcina amanzi ethambile ukuba ubetha;

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.
