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 yeselulosi 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 kunokungaphuculi 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 kunye nokunciphisa 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 nokunyanga ixesha kunye nobushushu, zinokuchaphazela i-hydration 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.
