Zeziphi izinto ezichaphazela ukugcinwa kwamanzi kwi-cellulose ether?

I-cellulose ethers, njenge-methyl cellulose (MC) kunye ne-hydroxyethyl cellulose (HEC), ziqhele ukusetyenziswa njengeejenti zokugcina amanzi kwizinto zokwakha ezifana nodaka olusekelwe kwisamente kunye ne-gypsum-based plasters.Ukugcinwa kwamanzi kwi-cellulose ethers kunokuphenjelelwa zizinto ezahlukeneyo:

1. Ubume beMichiza: Ubume bemichiza ye-cellulose ethers ichaphazela iimpawu zabo zokugcina amanzi.Umzekelo, i-hydroxyethyl cellulose (HEC) idla ngokubonisa ukugcinwa kwamanzi okuphezulu xa kuthelekiswa ne-methyl cellulose (MC) ngenxa yobukho bamaqela e-hydroxyethyl, ephucula umthamo wokubopha amanzi.
2. Ubunzima beMolekyuli: I-ethers ephezulu ye-molecular weight cellulose ikholisa ukuba neepropati ezingcono zokugcina amanzi kuba zenza uthungelwano olubanzi lwe-hydrogen bonding kunye neemolekyuli zamanzi.Ngenxa yoko, i-cellulose ethers ezinobunzima obuphezulu bemolekyuli ngokubanzi zigcina amanzi ngokufanelekileyo kunezo zinee-molekyuli ezisezantsi.
3. Umthamo: Ubungakanani be-ether ye-cellulose eyongeziweyo kumxube wodaka okanye udaka luchaphazela ngokuthe ngqo ukugcinwa kwamanzi.Ukonyusa idosi ye-cellulose ether ngokubanzi kwandisa ugcino lwamanzi, ukuya kutsho kwindawo ethile apho ukongeza okongezelelekileyo kusenokungaphuculi kakhulu ukugcinwa kwaye kunokuchaphazela kakubi ezinye iimpawu zemathiriyeli.
4. Ubungakanani beNcam kunye noSasazo: Ubungakanani beqhekeza kunye nokuhanjiswa kwe-cellulose ethers kunokuchaphazela ukusasazeka kwabo kunye nokusebenza kakuhle ekugcineni amanzi.I-ethers ye-cellulose ephantsi komhlaba kunye nokusabalalisa ubungakanani bamasuntswana afanayo ithande ukusasazeka ngokulinganayo kumxube, okukhokelela ekuphuculeni ukugcinwa kwamanzi.
5. Iqondo lobushushu kunye nokufuma: Iimeko zokusingqongileyo, ezifana neqondo lobushushu kunye nokufuma, zinokuchaphazela ukufakwa kwamanzi kunye nokugcinwa kwamanzi kwi-cellulose ethers.Amaqondo obushushu aphezulu anokukhawulezisa inkqubo yokufakwa kwamanzi, okukhokelela ekufunxeni kwamanzi ngokukhawuleza kunye nokunciphisa ukugcinwa kwamanzi.Ngokuchaseneyo, iimeko zokufuma okuphantsi zinokukhuthaza ukuvela kwamanzi kwaye kunciphise ukugcinwa kwamanzi.
6. Uhlobo lwe-Cement kunye neZongezo: Uhlobo lwesamente kunye nezinye izongezo ezikhoyo kwi-mortar okanye umxube we-plaster zingasebenzisana ne-cellulose ethers kwaye ziphembelele iimpawu zabo zokugcina amanzi.Ezinye iintlobo zesamente okanye izongezo zinokuphucula okanye zithintele ukugcinwa kwamanzi ngokuxhomekeke ekusebenzisaneni kwazo neekhemikhali ze-cellulose ethers.
7. Inkqubo yokuxuba: Inkqubo yokuxuba, kubandakanywa ixesha lokuxuba, isantya sokuxuba, kunye nomyalelo wokongezwa kwezithako, kunokuchaphazela ukusabalalisa kunye ne-hydration ye-cellulose ethers kumxube.Iindlela zokuxuba ezichanekileyo ziyimfuneko ukuze kuqinisekiswe ukuhanjiswa okufanayo kwee-cellulose ethers kunye nokwandisa ukugcinwa kwamanzi.
8. Iimeko zokunyanga: Iimeko zokunyanga, ezifana nexesha lokunyanga kunye nobushushu, zinokuchaphazela ukuhanjiswa kunye nokugcinwa kwamanzi kwi-cellulose ethers kwizinto eziphilisiweyo.Ukunyanga okwaneleyo kuyimfuneko ukuvumela i-cellulose ethers ukuba i-hydrate ngokupheleleyo kwaye ifake isandla ekugcinweni kwamanzi ixesha elide kwimveliso enzima.

Ngokuqwalasela le miba, iingcali zokwakha zinokwandisa ukusetyenziswa kwee-ethers ze-cellulose njengeejenti zokugcina amanzi kudaka kunye nokwakhiwa kodaka ukuze kuphunyezwe iimpawu zokusebenza ezinqwenelekayo ezifana nokusebenza, ukunamathela, kunye nokuqina.
