I-Hydroxyethylmethylcellulose (HEMC) i-ether ye-cellulose engeyiyo i-ionic esetyenziswa ngokubanzi kwimibhobho yokwakha, ngokukodwa kwi-dry-mix mortars, i-plastering mortars, i-self-leveling mortars kunye ne-adhesives tile. Iinzuzo zayo eziphambili zibonakaliswa ekuphuculeni ukusebenza kodaka, ukuphucula iimpawu zomatshini kunye nokuphucula ukusebenza kakuhle kokwakhiwa.
1. Ukwandisa ukugcinwa kwamanzi kwidaka
I-HEMC ineempawu ezigqwesileyo zokugcina amanzi, nto leyo ebalulekileyo kwizicelo zodaka. Ekubeni i-samente idinga i-hydration eyaneleyo ngexesha lenkqubo yokuqina, kwaye indawo yendawo yokwakha ihlala yomile, amanzi alula ukuba abe ngumphunga, ngakumbi phantsi kobushushu obuphezulu okanye iimeko ezinomoya. I-HEMC inokunciphisa kakhulu ukulahlekelwa kwamanzi kwaye iqinisekise ukuchithwa okwaneleyo kwe-samente, ngaloo ndlela iphucula amandla kunye nokudibanisa amandla omdaka. Kwangaxeshanye, ukugcinwa kakuhle kwamanzi kukwanceda ukuphepha iintanda ezinciphayo kumdaka kunye nokuphucula umgangatho wokwakha.
2. Ukuphucula ukusebenza kodaka
I-HEMC inokuphucula ngokufanelekileyo ukusebenza kunye nokuguquguquka kodaka, okwenza kube lula ukusebenzisa kunye nenqanaba. Emva kokongeza inani elifanelekileyo le-HEMC kumdaka, i-lubricity kunye ne-slipperiness of mortar inokuphuculwa, ivumela abasebenzi ukuba benze ukwakhiwa ngokulula kunye nokuphucula ukusebenza kakuhle. Ukongezelela, i-HEMC inokwandisa ixesha lokuvula udaka, ukuvumela abasebenzi ukuba bahlengahlengise iinkcukacha zokwakha ngokulula kwixesha elithile, ngaloo ndlela kuphuculwe umphumo wokwakha.
3. Ukuphucula ukunamathela kodaka
Ukusebenza kokubambisana kodaka luphawu olubalulekileyo lokuqinisekisa umgangatho wokwakha. I-HEMC inokuphucula amandla okudibanisa phakathi kodaka kunye nesiseko sezinto eziphathekayo, ngaloo ndlela iphucula ukusebenza kokubambelela kodaka. Oku kubaluleke kakhulu kwizicelo ezifana ne-tile yokunamathela kunye ne-thermal insulation mortar, njengoko inokuphepha ngokufanelekileyo iingxaki ezifana nokugoba kunye nokuwa ngenxa yokunganyaniseki ngokwaneleyo.
4. Ukuphucula ukumelana nokutyibilika kodaka
Ngexesha lenkqubo yokubeka i-tile ye-ceramic, ukusebenza kwe-anti-slip kubalulekile, ngakumbi kwiithayile ze-ceramic ezinobungakanani obukhulu okanye ukwakhiwa kodonga. I-HEMC inokuphucula ngokufanelekileyo ukusebenza kwe-anti-slip ngokulungisa i-viscosity kunye nokuhambelana komdaka, ukuqinisekisa ukuba iileyile ze-ceramic zifakwe ngokuzinzileyo kwisiseko sesiseko kwinqanaba lokuqala ngaphandle kokufuduka. Olu phawu lubaluleke kakhulu kulwakhiwo oluthe nkqo.
5. Ukwandisa ukumelana nokuqhekeka kunye nokuguquguquka kodaka
HEMC inokuphucula ukuguquguquka kunye nokumelana nokuqhekeka kodaka ukuya kumlinganiselo othile. Ukugcinwa kwayo kwamanzi kunye ne-rheology kwandisa ukusabalalisa uxinzelelo ngaphakathi kodaka kunye nokunciphisa umngcipheko wokuqhekeka okubangelwa yi-shrinkage eyomileyo kunye nokuhluka kweqondo lokushisa. Ukongezelela, kwiindawo ezikhethekileyo, ezifana nokwakhiwa kweqondo eliphezulu langaphandle okanye ukwakhiwa kweqondo lokushisa eliphantsi, ukongezwa kwe-HEMC kunokulungelelanisa ngakumbi utshintsho lweqondo lokushisa kunye nokwandisa ubomi benkonzo yodaka.
6. Ukuphucula ukusebenza ngokuzimeleyo
Kwimizila yokuzimela, i-rheological adjustment effect ye-HEMC ibaluleke kakhulu. Ukutyeba kwayo okugqwesileyo kunye namandla okulawula i-rheology yenza ukuba udaka lukwazi ukuzilinganisa ngexesha lolwakhiwo ukwenza umphezulu ogudileyo kunye nothe tyaba, ngelixa unqanda i-delamination okanye ukuhlaliswa kunye nokuphucula umgangatho uwonke wokwakhiwa komgangatho.
7. Uqoqosho kunye nokusingqongileyo
Nangona i-HEMC isongezo esisebenzayo, idosi idla ngokuba yincinci kwaye ngoko ayinyusi kakhulu iindleko zodaka. Ukongezelela, i-HEMC ngokwayo ayinayo ityhefu kwaye ayinabungozi, ayinayo isinyithi esinzima okanye i-volatile organic compounds (VOC), kwaye ihlangabezana neemfuno zokukhusela okusingqongileyo. Oku kuyenza ilungele uzinzo kushishino lokwakha.
I-Hydroxyethyl methylcellulose ineenzuzo ezininzi zokusebenza kudaka kwaye inokuphucula kakhulu iipropati eziphambili ezifana nokugcinwa kwamanzi, ukusebenza, ukunamathela kunye nokuchasana nodaka. Ezi mpawu aziphuculi nje ukusebenza kakuhle kolwakhiwo kunye nomgangatho weprojekthi, kodwa zinciphisa imingcipheko kunye neendleko zokugcina ngexesha lenkqubo yokwakha. Ke ngoko, i-HEMC inethemba elibanzi lokusetyenziswa kwezinto zokwakha zale mihla kwaye iye yaba sisongezo esiyimfuneko nesibalulekileyo.
