I-HydroxyPOpyl Methylcelcelse

I-HydroxyPOpyl Methylcelceltulose (HPMC), njenge-Isuplose eqhelekileyo, isetyenziswa ngakumbi kwizinto zokwakha, ngakumbi i-Gyppum-esekwe kwi-Gyppum-esekwe kwi-Gypsim kunye neemveliso zeGypsim. I-HPMC inomoya ofanelekileyo wamanzi, ukugcinwa kwamanzi, ukugcinwa kwamanzi kunye nezinto ezenziweyo zefilimu, kwaye ke idlala indima ebalulekileyo kwimveliso kunye nokusetyenziswa kweemveliso ze-gypsim.

Iipropati ezisisiseko ze-hydroxypropyl methylcelcelculose (hpmc)
I-HPMC yi-ionic selsulose ether, ebizwa emva kokuqaliswa kwe-hydroxypropy kunye namaqela e-methyl kwimolekyuli. Iipropati zayo ezisisiseko zibandakanya:

Ukuluka: i-HPMC inokunyibilikisa ngokukhawuleza emanzini ebandayo ukwenza isisombululo esibonakalayo okanye kancinci isisombululo se-colloid.
Ukutyibilika: i-HPMC inefuthe elihle kakhulu kwaye linokunyusa i-viscosity yesisombululo.
Ukugcinwa kwamanzi: i-HPMC inokuhlala imanyiwe ixesha elide xa amanzi evala, ewathintela amanzi ukuba alahleke ngokukhawuleza.
Ukwenza ifilimu: I-HPMC inokwenza ifilimu eguqukayo nengabonakaliyo emva komile.
Ezi mpawu zenza i-HPMC i-adsorting ebalulekileyo kwi-Gyppum-esekwe kwi-Gyppum kunye neemveliso zeGypsim.

Ukusetyenziswa kwe-HPMC kwi-Gyppum-esekwe
I-Gyppum-esekwe kwi-Gyppum-esekwe ngaphakathi nangasemva kwempahla yokuhombisa kwizakhiwo zanamhlanje, ubukhulu becala ye-gidpsum ye-hydam, i-agergates kunye neezongezo ezahlukeneyo. Ukusetyenziswa kwe-HPMC kwi-Gypsim-esekwe ikakhulu kuboniswa ikakhulu kwezi zinto zilandelayo:

Isiphumo sokuqaqamba: I-HPMC inokunyusa kakhulu i-viscofity ye-Gyppum-esekwe kwiGyppum, esenza i-Plaster isebenza ngakumbi ngexesha lolwakhiwo kunye nokuthintela ukungcungcutheka kunye ne-SAG.
Iziphumo zokugcina amanzi: Ngenxa yokugcinwa kwe-HPMC ye-HPMC, iqondo lokuphuma kwamanzi e-Gypsim lingayibala ngokufanelekileyo, ukuqinisekisa ukuba inkqubo eyaneleyo yokuthatha inxaxheba kunye nokuthathwa kwengqondo emva kokukhanya.
Ukuphuculwa kokuSebenza kokwakha: I-HPMC inokuphucula i-qubrity kunye nolwelo lweplastimu esekwe kwiGyppum, esenza kube lula ukusasazeka kwaye igudile ngexesha lokwakha, ukunciphisa ubunzima bokwakha kunye nokuphucula ukusebenza ngokukuko.
Ukunganyangeki: Ngokwandisa ukuguquguquka kweplasta, i-HPMC inokukunciphisa ngokufanelekileyo ukuqhekeka okubangelwa kukuntywila kwaye kwandise ubomi benkonzo yomhlobiso.

Ukusetyenziswa kwe-HPMC kwiimveliso ze-gypsim
Ukongeza kwisicelo sayo kwiPlasters-esekwe kwiGypsim, i-HPMC isetyenziswa ngokubanzi kwiimveliso ezahlukeneyo ze-gypsim, ezinjengeBhodi yeGypsim, imigca ye-Gypsim, ukongezwa kwe-HPMC inokuzisa iziphumo ezibalulekileyo:

Ukuguqulwa kunye nokutyibilika: ukongeza i-HPMC ukuya kwi-Gypsim Slarry kunokuphucula i-viscofity ye-gixit, yenza ukuba i-throptropy igcwalise i-probries yayo, yehlisa imigangatho yemveliso ephezulu.
Ukuphucula ubuchule kunye namandla: Isakhiwo sefilimu ezenziwa yi-HPMC ngexesha lenkqubo yokukhula sinokunyusa ukuguquguquka kunye nokungaxhathisi kweemveliso zeGypsim kwaye kunciphise ukonakala ngexesha lokuhamba kunye nokufakwa.
Ukuphucula ukugcinwa kwamanzi: i-HPMC inokugcina imeko enomswakama ixesha elide ngexesha lenkqubo yokomisa ye-Gypsim, ukunqanda ukuqhekeka kunye nokudakumba okubangelwa kukusoma ngokukhawuleza.
I-intermy ye-interm: i-HPMC inokwenza i-gypsum slurry isasazwe ngokulinganayo ekubumbeni, iphucule ukuxinana kunye nokufana kwemveliso, kunye nokuqinisekisa ukuchaneka kwemveliso kunye nokugqibezela komgangatho.

Ukusetyenziswa kwe-hydroxypropyl methylcelcellulose (i-HPMC) e-Gypsim-esekwe kwi-Gypsim kunye neemveliso zeGypsim zinezibonelelo ezibalulekileyo. Ngokuphucula ukugcinwa, ukugcinwa kwamanzi, ukwenza ifilimu kunye nezinye iipropathi, i-HPMC ayiphuluki kuphela ukwakhiwa kolwakhiwo kunye nomgangatho wemveliso egqityiweyo, kodwa ikwandisa inkonzo yenkonzo ye-gypsim. Kwixesha elizayo lophando kunye nophuhliso kunye nokusetyenziswa kwezinto zokwakha, i-HPMC, njengesongezelelo esibalulekileyo, siya kuqhubeka nokudlala indima eyahlukileyo kwaye senze iminikelo emikhulu kuphuhliso lweshishini lokwakha.
