Ukongeza i-HPMC inceda ukuthintela udaka lomxube owomileyo ukuba ungagxuphuleki kunye nokuqhekeka.Oku kunenzuzo ngakumbi kwizicelo ezithe nkqo apho udaka lufuna ukunamathela kumphezulu ngaphandle kokuwa okanye ukuqhekeka ngexesha lenkqubo yokunyanga.

6. Impembelelo kwi-rheology

I-HPMC itshintsha iipropati ze-rheological zodaka olomileyo, oluchaphazela ukuziphatha kwayo kunye ne-viscosity.Oku kuqinisekisa ukuba i-mortar ingasetyenziswa kwaye isasazeke ngokulula ngelixa igcina ubukhulu obufunekayo kunye nokuhambelana.

Iingenelo zokusebenzisa i-HPMC kumxube owomileyo wodaka

1. Ukuvisisana nomanyano

I-HPMC inceda ukugcina umgangatho wodaka lomxube owomileyo, ukuqinisekisa ukufana kweempawu ezifana nokusebenza, ukunamathela kunye nokugcinwa kwamanzi.Oku kubalulekile ekufumaneni iziphumo ezithembekileyo neziqikelelwayo kwizicelo zokwakha.

2. Yandisa iiyure zokuvula

Ixesha elivulekileyo lodaka lixesha apho udaka luhlala lusetyenziswa emva kokuxuba.I-HPMC yandisa ixesha elivulekileyo, ibonelela ngokuguquguquka ngexesha lokwakha, kwaye inciphisa amandla okomisa kwangaphambi kwexesha.

3. Ukomeleza ukuqina

Ukugcinwa kwamanzi kunye neempawu zokubambelela ezinikezelwa yi-HPMC zinceda ukuphucula ukuqina komxube owomileyo.Ukuqulunqwa kodaka usebenzisa i-HPMC akuthandeki kangako kwiingxaki ezifana nokuqhekeka, okunokuthi kuphazamise ingqibelelo yexesha elide yesakhiwo.

4. Ukuguquguquka

I-HPMC iyahambelana neentlobo ezahlukeneyo zokwenziwa kodaka, iyenza isongezo esisebenza ngeendlela ezahlukeneyo kwizinto ezahlukeneyo zokwakha.Inokudibaniswa kunye nezinye izongezo zokufezekisa iimfuno ezithile zokusebenza.

Ukusetyenziswa kwe-HPMC kudaka olomileyo oluxutyiweyo

1. Ukutyabeka udaka

Kwiidaka zokutyabeka, i-HPMC ithintela ukudilika kunye nokuphucula ukunamathela kwi-substrate, inceda ukufezekisa ukugudiswa, kunye nomphezulu.

2. I-adhesive ye-tile

I-HPMC idla ngokusetyenziswa kwiindlela zokuncamathelisa iithayile ukunyusa ukuncamathelisa, ukugcinwa kwamanzi kunye nokuxhathisa i-sag, ukuqinisekisa ibhondi ethembekileyo phakathi kwethayile kunye ne-substrate.

3. Udaka lwamatye

Kwimibhobho ye-masonry, i-HPMC inceda ukuphucula ukusebenza kolwakhiwo kunye nokuqina, okukhokelela ekusebenzeni, udonga oluhlala ixesha elide kunye nolwakhiwo lwezakhiwo.
