Indima ebalulekileyo ye-HPMC kwi-mortar exutywe ngamanzi

Indima ebalulekileyo ye-HPMC kwi-mortar exutywe ngamanzi ikakhulu inale miba mithathu ilandelayo:

1. I-HPMC inomthamo obalaseleyo wokugcina amanzi.

2. Impembelelo ye-HPMC ekuqineni nasekuqineni kwe-thixotropy ye-mortar exutywe ngamanzi.

3. Intsebenziswano phakathi kwe-HPMC kunye nesamente.

Ukugcinwa kwamanzi ngumsebenzi obalulekileyo we-HPMC, kwaye kukwangumsebenzi oqwalaselwa kakhulu ngabavelisi abaninzi be-wet-mixed mortar.

Isiphumo sokugcina amanzi se-HPMC sixhomekeke kwisantya sokufunxwa kwamanzi kwisiseko somaleko, ukwakheka kwesamente, ubukhulu somaleko wesamente, imfuno yamanzi yesamente, kunye nexesha lokuseta izinto zokuseta.

I-HPMC - ukugcinwa kwamanzi

Okukhona ubushushu bejeli ye-HPMC buphezulu, kokukhona ukugcinwa kwamanzi kuphucuka.

Izinto ezichaphazela ukugcinwa kwamanzi kwe-mortar exutywe ngamanzi kukuxinana kwe-HPMC, ubungakanani bokongeza, ubuncinci bee-particles kunye nobushushu bokusetyenziswa.

Ukuqina kwe-viscosity yiparameter ebalulekileyo yokusebenza kwe-HPMC. Kwimveliso efanayo, iziphumo ze-viscosity ezilinganiswa ngeendlela ezahlukeneyo ziyahluka kakhulu, kwaye ezinye zide ziphindaphinde umahluko. Ke ngoko, xa kuthelekiswa ukuqina kwe-viscosity, kufuneka kwenziwe phakathi kweendlela zovavanyo ezifanayo, kubandakanya ubushushu, i-spindle, njl. Ngokubanzi, okukhona ukuqina kwe-viscosity kuphezulu, kokukhona isiphumo sokugcina amanzi singcono.

Nangona kunjalo, okukhona i-viscosity iphezulu kwaye ubunzima be-molecular ye-HPMC bukhulu, ukwehla kokunyibilika kwayo kuya kuba nefuthe elibi kumandla kunye nokusebenza kolwakhiwo lwe-mortar. Okukhona i-viscosity iphezulu, kokukhona isiphumo sokuqina kwe-mortar sibonakala ngakumbi, kodwa asilingani. Okukhona i-viscosity iphezulu, kokukhona i-mortar emanzi ixinene ngakumbi, nto leyo ebonisa ukunamathela kwi-scraper ngexesha lokwakhiwa kunye nokunamathela okuphezulu kwi-substrate. Nangona kunjalo, i-HPMC ayinampembelelo ingako ekuphuculeni amandla olwakhiwo lwe-mortar emanzi ngokwayo, nto leyo ebonisa ukuba ukusebenza kokungawi akubonakali. Ngokuchasene noko, ezinye i-HPMC ezilungisiweyo ezine-viscosity ephakathi nephantsi zibalaseleyo ekuphuculeni amandla olwakhiwo lwe-mortar emanzi.

Ukuqina kwe-HPMC kunempembelelo ethile ekugcinweni kwamanzi. Ngokubanzi, kwi-HPMC ene-viscosity efanayo kodwa enobuncinci obahlukeneyo, kokukhona i-HPMC incinci, kokukhona isiphumo sokugcinwa kwamanzi singcono phantsi komlinganiselo ofanayo wokongeza.
