I-Hydroxypropyl methylcellulose yi-ether ye-cellulose engeyiyo-ionic ecutshungulwa ukusuka kwikotoni esulungekileyo ngoluhlu lwee-chemical reactions.Yinto engenavumba, engeyotyhefu engumgubo omhlophe enyibilika emanzini kwaye inikezela ngesisombululo esicacileyo okanye esinamafu kancinane we-colloidal.Ineempawu zokuqina, ukugcinwa kwamanzi kunye nokwakhiwa okulula.Isisombululo samanzi se-hydroxypropyl methylcellulose HPMC sizinzile kuluhlu lwe-HP3.0-10.0, kwaye xa lungaphantsi kwe-3 okanye likhulu kune-10, i-viscosity iya kuncitshiswa kakhulu.
Umsebenzi oyintloko we-hydroxypropyl methylcellulose kwi-sement mortar kunye ne-putty powder kukugcinwa kwamanzi kunye nokuqina, okunokuphucula ngokufanelekileyo ukubambisana kunye nokuxhatshazwa kwe-sag yezinto.
Izinto ezinje ngeqondo lobushushu kunye nesantya somoya ziyakuchaphazela isantya sokunyakama kokunyakama kudaka, iputty kunye nezinye iimveliso, ke kumaxesha ahlukeneyo onyaka, isiphumo sokugcinwa kwamanzi kwiimveliso ezinobungakanani obufanayo beselulosi esongeziweyo siya kuba nokwahluka.Kulwakhiwo oluthile, umphumo wokugcinwa kwamanzi we-slurry unokulungiswa ngokunyuka okanye ukunciphisa inani le-HPMC elongezelelweyo.Ukugcinwa kwamanzi kwe-hydroxypropyl methylcellulose HPMC kwiqondo lokushisa eliphezulu luphawu olubalulekileyo lokuhlukanisa umgangatho we-HPMC.I-HPMC egqwesileyo inokusombulula ngempumelelo ingxaki yokugcinwa kwamanzi phantsi kweemeko eziphezulu zokushisa.Kwixesha elomileyo kunye neendawo ezinobushushu obuphezulu kunye nesantya esiphezulu somoya, kuyimfuneko ukusebenzisa i-HPMC ephezulu yokuphucula ukugcinwa kwamanzi kwi-slurry.
Ngoko ke, kwiqondo eliphezulu lokwakhiwa kwehlobo, ukuze kufezekiswe umphumo wokugcinwa kwamanzi, kuyimfuneko ukongeza inani elaneleyo le-HPMC ekumgangatho ophezulu ngokwefomula, kungenjalo kuya kubakho iingxaki ezisemgangathweni ezifana nokungonelanga kwe-hydration, ukunciphisa amandla, ukuqhekeka. , umgodi kunye nokuchithwa okubangelwa ukomisa ngokukhawuleza, kwaye ngexesha elifanayo Kwakhona kwandise ubunzima bokwakhiwa kwabasebenzi.Njengoko iqondo lokushisa liyehla, inani le-HPMC elongezelelweyo lingancitshiswa ngokuthe ngcembe, kwaye umphumo ofanayo wokugcinwa kwamanzi unokufumaneka.
Kwimveliso yezinto zokwakha, i-hydroxypropyl methylcellulose sisongezo esiyimfuneko.Emva kokongeza HPMC, ezi propati zilandelayo zingaphuculwa:
1. Ukugcinwa kwamanzi: Ukuphucula ukugcinwa kwamanzi, ukuphucula udaka lwesamente, iputty eyomileyo yomiswe ngokukhawuleza kunye nokungonelanga kwe-hydration kubangele ukuqina okungahambi kakuhle, ukuqhekeka kunye nezinye izinto.
2. Ukubambelela: Ngenxa yeplastiki ephuculweyo yodaka, inokudibanisa ngcono i-substrate kunye ne-adherend.
3. I-Anti-sagging: Ngenxa yempembelelo yayo yokuqina, inokuthintela ukutyibilika kodaka kunye nezinto ezinamathele ngexesha lokwakha.
4. Ukusebenza: Ukwandisa iplastiki yodaka, ukuphucula ushishino lokwakha kunye nokuphucula ukusebenza kakuhle.
