Viscosity of cellulose ether HPMC for self-leveling mortar

I-viscosity ye-Hydroxypropyl Methylcellulose (HPMC) esetyenziswa kwi-self-leveling mortar formulations yiparameter ebalulekileyo echaphazela ukuziphatha kokuhamba, ukusebenza, kunye nokusebenza kodaka. Iifama zokuzilinganisa ziyilelwe ukuba zihambe ngokulula kwaye zizenzele ngokwazo ngaphandle kwe-troweling, ukwenza ulawulo lwe-viscosity luyimfuneko ekufezekiseni iipropati ezifunwayo. Nantsi isikhokelo esibanzi sokukhetha i-viscosity ye-HPMC yodaka lokuzilinganisa:

1. AmaBanga e-Viscosity ephantsi: Izixhobo zokuzilinganisa ngokuqhelekileyo zifuna i-HPMC ene-viscosity ephantsi ye-400 amabakala e-CPS. La mabanga e-HPMC abonelela ngokuqukuqela okuyimfuneko kunye neempawu zokulinganisa kudaka ngelixa ligcina ubumbano olufanelekileyo kunye nokuzinza.
2. Uluhlu lweViscosity eKhethekileyo: Uluhlu oluthile lwe-viscosity ye-HPMC esetyenziswa kwi-self-leveling mortar formulations inokwahluka ngokuxhomekeke kwizinto ezifana nokuhamba okufunwayo, ubukhulu besicelo, ubushushu be-ambient, kunye nexesha lokunyanga. Nangona kunjalo, amabanga e-viscosity kuluhlu lwe-400 mPa·s aqhele ukusetyenziswa kwi-self-leveling mortars.
3. Ukusebenza kunye noLawulo lokuHamba: I-viscosity ye-HPMC kufuneka ihlengahlengiswe ukufezekisa ukusebenza okufunekayo kunye nolawulo lokuhamba kodaka oluzilinganisayo. Amanqanaba asezantsi e-viscosity abonelela ngokuqukuqela okukhulu kunye nokusasazeka lula, ngelixa amabakala aphezulu e-viscosity anika ulawulo olungcono lokuhamba kunye neempawu zokulinganisa.
4. Ukuhambelana nezinye izongezo: I-HPMC esetyenziswa kwimixube yodaka lokuzilinganisa kufuneka ihambelane nezinye izongezo ezifana ne-superplasticizers, i-air entrainers, kunye ne-defoamers. I-viscosity ye-HPMC kufuneka ikhethwe ukuqinisekisa ukuhambelana nezi zongezo kunye nokugcina iimpawu ezifunwayo zodaka.
5. Ulawulo loMgangatho kunye noVavanyo: Kubalulekile ukwenza uvavanyo lolawulo lomgangatho olucokisekileyo ukumisela eyona viscosity ye-HPMC yokwenziwa kodaka oluzilinganisayo. Uvavanyo lunokubandakanya imilinganiselo ye-rheological, iimvavanyo zokuqukuqela, kunye nokuvavanya ukusebenza phantsi kweemeko ezifaniswayo zesicelo.
6. Iingcebiso zabavelisi: Abavelisi be-HPMC babonelela ngedatha yedatha yobugcisa kunye nezikhokelo ezichaza amabakala e-viscosity acetyiswayo kwizicelo ezahlukeneyo, kubandakanywa udaka lokuzilinganisa. Kuyacetyiswa ukuba udibane nezi ngcebiso kwaye usebenze ngokusondeleyo nomthengisi we-HPMC ukuze ukhethe elona bakala lifanelekileyo le-viscosity kwisicelo sakho esithile.

Isishwankathelo, i-viscosity ye-HPMC yodaka lokuzilinganisa kufuneka ikhethwe ngononophelo ngokusekelwe ekuphumeni okufunwayo, ukusebenza, kunye neemfuno zokusebenza kodaka, kuthathelwa ingqalelo izinto ezifana nobukhulu besicelo, iimeko ze-ambient, ukuhambelana nezinye izongezo, kunye nomvelisi. iingcebiso.
