Njengomvelisi we-HPMC oqeqeshiweyo, sikholelwa ukuba i-Hydroxypropyl Methyl Cellulose (HPMC) yenye yezona zinto ziguquguqukayo nezithembekileyo ze-cellulose ethers ezisetyenziswa kumashishini ahlukeneyo axhomekeke kwizongezo zekhemikhali ngenjongo ethile.
Enye yezona zinto zibalulekileyo ze-HPMC kukukwazi ukugcina amanzi. Oku kuyenza ilungele usetyenziso olubanzi kulwakhiwo, izithambiso, amayeza kunye namashishini okutya.
Nangona kunjalo, ngaphandle kweenzuzo ezininzi ze-HPMC, umthamo wayo wokugcina amanzi unokuchatshazelwa zizinto ezininzi, ezinokuchaphazela kakubi ukusebenza kwayo. Ngezantsi zezinye zezona zinto zixhaphakileyo ezichaphazela amandla okugcina amanzi e-HPMC.
1. Ubushushu
Iqondo lobushushu yenye yezona zinto zibalulekileyo ezichaphazela amandla okugcina amanzi e-HPMC. Njengoko ubushushu busanda, i-HPMC ithande ukuphulukana nomthamo wayo wokugcina amanzi. Ngoko ke, ukuba iqondo lobushushu liphezulu kakhulu, i-HPMC ayinakugcina amanzi aneleyo kusetyenziso lwayo.
Ngoko ke, kucetyiswa ukuba ugcine i-HPMC kwindawo epholileyo neyomileyo ukuthintela ukuthotywa kokusebenza ngenxa yokutshatyalaliswa kobushushu.
2. Ukufuma
Ukufuma bubuninzi bamanzi akhoyo emoyeni. I-HPMC ifunxa ukufuma emoyeni, echaphazela isakhono sayo sokubamba amanzi. Ukuba ukufuma kuphezulu kakhulu, i-HPMC iyakufunxa ukufuma okuninzi okuvela emoyeni, ibangele iingxaki ezifana ne-caking kunye nokuqina.
Ngoko ke, kubalulekile ukugcina i-HPMC kwizikhongozeli ezingangeni moya ukunqanda ukuba sesichengeni sokufuma nokufuma.
3. pH
Ixabiso le-pH lokusingqongileyo liya kuchaphazela nogcino lwamanzi lwe-HPMC. I-HPMC isebenza ngcono kwiindawo ezineasidi kancinane okanye ezingathathi hlangothi kwi-pH. Nangona kunjalo, kwiindawo ezineasidi kakhulu okanye ezinealkaline, amandla okugcina amanzi e-HPMC aya kuncitshiswa kakhulu.
Ngoko ke, kubaluleke kakhulu ukuqinisekisa ukuba indawo apho i-HPMC isetyenziswa khona iphakathi koluhlu lwe-pH olwamkelekileyo.
4. Ubungakanani besuntswana
Ubungakanani bamasuntswana e-HPMC bukwachaphazela amandla okugcina amanzi. Amasuntswana amancinci akholisa ukuba nommandla ongaphezulu komhlaba ukuya kumlinganiselo womthamo, nto leyo enokukhokelela ekwandeni komthamo wokugcina amanzi.
Ngoko ke, kwizicelo ezifuna umthamo ophezulu wokugcinwa kwamanzi, i-particle encinci ye-HPMC iyacetyiswa.
5. Isantya sokunyibilika
Izinga lokupheliswa kwe-HPMC likwachaphazela amandla ayo okugcina amanzi. I-HPMC enesantya esicothayo sokuchithwa ithande ukuba nomthamo ophezulu wogcino lwamanzi kune-HPMC enesantya esikhawulezayo sokuchithwa.
Ngoko ke, kwizicelo ezifuna umthamo ophezulu wokugcinwa kwamanzi, i-HPMC enezinga eliphantsi lokuchithwa iyacetyiswa.
ukuququmbela
Isishwankathelo, njengomvelisi we-HPMC, sithatha amandla okugcina amanzi e-HPMC njengenye yezona zinto zibalulekileyo. Nangona kunjalo, kubalulekile ukuqwalasela izinto ezahlukeneyo ezichaphazela amandla ayo okubamba amanzi.
Ngoko ke, kubalulekile ukuqinisekisa ukuba i-HPMC igcinwe kwindawo epholileyo, eyomileyo, kwisitya esingenawo umoya, kwindawo ene-pH efanelekileyo, kunye nobukhulu be-particle encinci kunye nesantya esincinci sokuchithwa kokugcinwa kwamanzi ngokufanelekileyo.
Ngokuthatha la manyathelo, HPMCs ukwenza kakuhle kuluhlu olubanzi izicelo.
