Njengomnye we-cellulose ether admixtures ebalulekileyo kwi-powder mortar, i-hydroxypropyl methylcellulose inemisebenzi emininzi kumdaka. Eyona ndima ibalulekileyo ye-hydroxypropyl methylcellulose kudaka lwesamente kukugcina amanzi kunye nokujiya. Ukongeza, ngenxa yokusebenzisana kwayo nenkqubo yesamente, inokudlala indima encedisayo ekufakeni umoya, ukubuyisela umva, kunye nokuphucula amandla ebhondi. isiphumo.
Eyona ntsebenzo ibalulekileyo ye-hydroxypropyl methylcellulose kumdaka kukugcina amanzi. Njengomxube we-ether cellulose kudaka, i-hydroxypropyl methylcellulose ingasetyenziswa phantse kuzo zonke iimveliso zodaka, ngakumbi ngenxa yokugcinwa kwamanzi. Ngokuqhelekileyo, ukugcinwa kwamanzi kwe-hydroxypropyl methylcellulose kuhambelana ne-viscosity yayo, i-degree of substitution and particle size.
I-Hydroxypropyl methylcellulose isetyenziswe njenge-thickener, kwaye umphumo wayo wokuqina uhambelana nenqanaba lokutshintshwa, ubungakanani beqhekeza, i-viscosity kunye neqondo lokuguqulwa kwe-hydroxypropyl methylcellulose. Ngokuqhelekileyo, iqondo eliphezulu lokuthatha indawo kunye ne-viscosity ye-cellulose ether, kunye namancinci amancinci, kokukhona kubonakala ngakumbi isiphumo sokuqina.
Kwi-hydroxypropyl methylcellulose, ukuqaliswa kwamaqela e-methoxy kunciphisa amandla angaphezulu kwesisombululo samanzi esine-hydroxypropyl methylcellulose, ukuze i-hydroxypropyl methylcellulose ibe nefuthe lokungenisa umoya kwi-samente mortar. Yazisa amaqamza omoya afanelekileyo kudaka, ngenxa “yempembelelo yebhola” yamaqamza omoya,
Ukusebenza kokwakhiwa komdaka kuphuculwe, kwaye ngexesha elifanayo, ukuqaliswa kweebhubhu zomoya kwandisa izinga lokukhutshwa komdaka. Ngokuqinisekileyo, umthamo wokungena emoyeni kufuneka ulawulwe. Ukungena emoyeni kakhulu kuya kuba nefuthe elibi kumandla omdaka.
I-Hydroxypropyl methylcellulose iya kulibazisa inkqubo yokumisela i-samente, ngaloo ndlela inciphisa ukuseta kunye nokuqina kwenkqubo ye-samente, kunye nokwandisa ixesha lokuvulwa kodaka ngokufanelekileyo, kodwa esi siphumo asilungile kumdaka kwimimandla ebandayo.
Njengomxokelelwane omde wepolymer, i-hydroxypropyl methylcellulose inokuphucula ukusebenza kwe-bonding kunye ne-substrate emva kokuba yongezwe kwinkqubo ye-samente phantsi kwesiseko sokugcina ngokupheleleyo umswakama kwi-slurry.
Ukushwankathela, ukusebenza kweHPMCkudaka ikakhulu kubandakanya: ukugcinwa kwamanzi, ukujiya, ukolula ixesha lokumisela, ukungenisa umoya kunye nokuphucula amandla okuqina kwebhondi, njl.
