5. Ukubambelela: I-HPMC iphucula ukunamathela kodaka kwii-substrates ezahlukeneyo, ukuphucula amandla okudibanisa.Oku kubalulekile kubomi obude kunye nokuzinza kwezinto ezakhiweyo.

I-HPMC kuLwakhiwo lodaka:

1. Ukuhambelana kunye nokusebenza: Ukongezwa kwe-HPMC kwiifom zodaka kuvumela abavelisi ukuba balawule ukuhambelana nokusebenza komxube.Oku kubalulekile ekufezekiseni iimpawu ezifunwayo zesicelo kunye nokulula ukusetyenziswa kwiindawo zokwakha.

2. Ugcino lwaManzi kunye nexesha elongeziweyo lokuVula: Iipropati zokugcina amanzi ze-HPMC ziluncedo ngakumbi kwizicelo zodaka.Ngokucotha inkqubo yokomisa, i-HPMC yandisa ixesha elivulekileyo lodaka, inika abasebenzi ixesha elaneleyo lokubeka izitena okanye iithayile.

3. Ukunamathela okuPhuculweyo: I-HPMC yongeza ukunamathela kodaka kwiindawo ezahlukeneyo, kubandakanywa izitena, amatye, kunye neethayile.Oku kunegalelo kumandla onke kunye nokuzinza kwezinto ezakhiweyo.

4. Ukomelezwa kokuqina: Iimpawu zokwenza ifilimu ye-HPMC zenza umaleko okhuselayo kumphezulu wodaka.Lo maleko wongeza ukuqina kodaka, nto leyo eyenza ukuba imelane nemozulu kunye nezinye izinto zokusingqongileyo.

5. I-Crack Resistance: I-film-forming capabilities ye-HPMC inegalelo kwi-crack resistance of the mortar.Oku kubaluleke kakhulu kwizicelo zokwakha apho izinto eziphathekayo zinokuthi zibe phantsi koxinzelelo kunye nokunyakaza.

6. Ukuhambelana nezinye izongezo: I-HPMC ihlala ihambelana neentlobo zezinye izongezo ezisetyenziswa ngokuqhelekileyo kwimixube yodaka.Oku kuhambelana kuvumela ukuguquguquka ekuqulunqweni, okwenza abavelisi balungelelanise udaka ukuhlangabezana neemfuno ezithile zokusebenza.

Izikhokelo zokuSebenzisa i-HPMC kuMortar:

1. Ukukhethwa kweBakala le-HPMC: Amanqanaba ngamanqanaba e-HPMC ayafumaneka, ngalinye lineempawu ezithile.Abavelisi kufuneka bakhethe ngokucophelela ibakala elifanelekileyo ngokusekelwe kwiimpawu ezifunwayo zodaka.Izinto ezifana ne-viscosity, i-degree of substitution, kunye ne-molecular weight idlala indima ebalulekileyo kule nkqubo yokhetho.

2. Iingqwalasela zokuqulunqa: Ukwenziwa kodaka kubandakanya ukulungelelana kwamacandelo ahlukeneyo, kubandakanywa i-aggregates, i-binders, kunye nezinye izongezo.I-HPMC idityaniswe ekuqulunqweni ukuncedisana nala macandelo kunye nokufezekisa iipropati ezifunwayo.

3. Ulawulo loMgangatho: Ukuqinisekisa ukusebenza ngokungaguqukiyo kokwenziwa kodaka, imilinganiselo yokulawula umgangatho ibalulekile.Ukuvavanya rhoqo kunye nokuhlalutya kunceda ukugcina iimpawu ezifunwayo zodaka kunye nokuthobela imigangatho yomgangatho.
