IHydroxyethyl methylcellulose (HEMC), njengekhompawundi yepolymer enyibilikayo esetyenziswa ngokuqhelekileyo emanzini, ineenzuzo ezibalulekileyo kwiingubo ezisekelwe kwisamente. Isakhiwo sayo samakhemikhali sivumela ukuba idlale indima ebalulekileyo ekuphuculeni ukusebenza kweengubo ezisekelwe kwi-samente.
1. Ukuphucula ukusebenza kolwakhiwo
Ngethuba lenkqubo yokwakhiwa kweengubo ezisekelwe kwi-samente, u-fluidity kunye nokusebenza zizinto ezibalulekileyo ezichaphazela umgangatho wokugquma kunye nokusebenza kakuhle kokwakhiwa. I-HEMC inokuphucula kakhulu ukusebenza kokwakhiwa kweengubo ngokunyusa i-viscosity kunye nokugcinwa kwamanzi kweengubo. Ukusebenza okuthe ngqo kuku:
Ukuphucula ukusebenza kwepeyinti: I-HEMC inokunyusa ukuhambelana kwepeyinti, okwenza kube lula ukulawula ipeyinti ngexesha lenkqubo yokugubungela kunye nokuphepha iingxaki ezifana nokuhamba kwepeyinti kunye nokuvuza.
Ukuphucula ukugcinwa kwamanzi kwiingubo: I-HEMC inokuphucula ukugcinwa kwamanzi kwi-cement-based based coatings, ukunciphisa izinga lokunyuka kwamanzi, kunye nokuqinisekisa ukufana kunye nokuzinza kwengubo.
Olu phawu lufanelekile ngokukodwa kwiimeko zokwakha ezifuna imisebenzi yexesha elide. Inokuqinisekisa ukuba i-sement slurry ayiyi kumisa ngaphambi kwexesha ngexesha lokwakhiwa kwengubo, ngaloo ndlela iqinisekisa umgangatho wokugqoka.
2. Yandisa iiyure zokuvula
Ixesha elivulekileyo lepeyinti esekwe kwisamente lixesha emva kokuba ipeyinti isetyenzisiwe ukuba isenokuguqulwa okanye igqitywe. Njenge-thickener esebenzayo, i-HEMC inokwandisa ixesha lokuvula i-cement-based coatings, ngaloo ndlela ikhulise ukuguquguquka kokwakhiwa. Emva kokongeza i-HEMC kwiingubo ezisekelwe kwi-samente, abasebenzi bezokwakha banokuba nexesha elingakumbi lokulungelelanisa i-coat and trimming ukuphepha iingxaki ezibangelwa ukunyangwa ngokukhawuleza kwengubo.
3. Ukuphucula ukunamathela kwepeyinti
HEMC inokuphucula ngokufanelekileyo ukunamathela phakathi kwengubo kunye ne-substrate kwiingubo ezisekelwe kwi-samente, ngokukodwa kwiindawo ezigudileyo okanye ezinzima-ukubopha i-substrate (njengesinyithi, iglasi, njl.). Ukongezwa kwe-HEMC kunokuphucula kakhulu ukunamathela kwengubo. Gxininisa. Ngale ndlela, kungekhona kuphela ukuqina kwengubo ephuculweyo, kodwa kunye nokukwazi ukuchasana nokuwa kwengubo kuphuculwe.
4. Ukuphucula ukuxhathisa kokuqhekeka kweengubo
Iingubo ezisekwe kwisamente zithande ukuqhekeka ngexesha lenkqubo yokunyanga, ngakumbi kwiingubo ezishinyeneyo okanye kwiindawo ezinobushushu obuphezulu. I-HEMC inokuphucula i-elasticity of coatings ngokusebenzisa isakhiwo sayo esisodwa se-molecular, ukunciphisa umthamo we-volume shrinkage obangelwa ukuguquguquka kwamanzi, kunye nokunciphisa ukuvela kweentanda. I-HEMC ingakwazi ukusebenzisana namanye amacandelo kwi-samente ukwenza isakhiwo sothungelwano esizinzile, ngakumbi ukuphucula ukuqina kunye nokumelana nokuqhekeka kwengubo.
5. Ukuphucula ukuxhathisa kwamanzi kwiingubo
Ukuxhathisa kwamanzi kwiingubo ezisekelwe kwisamente kubalulekile kwisakhiwo sangaphandle, amagumbi angaphantsi, kunye nezinye iindawo ezivezwe kukufuma okanye amanzi. Iipropati zokugcina amanzi ze-HEMC zinokucotha ngokufanelekileyo ukulahlekelwa kwamanzi kwiingubo ezisekelwe kwi-samente, ngaloo ndlela kuphuculwe ukuxhathisa kwamanzi kwengubo. Ukongezelela, i-HEMC inokubambisana kunye nezithako kwi-samente ukuze kuphuculwe amandla okumelana nokungena kwengubo, ngaloo ndlela iphucula ukusebenza kokungena kwamanzi kwengubo.
6. Ukuphucula i-rheology yeengubo
Ukusetyenziswa kwe-HEMC kwiingubo ezisekelwe kwi-samente kunokuphucula i-rheology yokugqoka, ukunika i-fluidity engcono kunye neempawu zokulinganisa. Emva kokongeza i-HEMC kwiingubo ezisekelwe kwi-samente, umbane we-coating ngexesha lenkqubo yokugquma iphuculwe, kwaye i-coating surface inokwenza i-coating smooth and more uniform coating, ukuphepha iziphene zokugubungela okubangelwa ukugqithisa okanye ukungalingani kwe-viscosity.
7. Ukusebenza kwendalo
Njengemveliso yendalo yepolysaccharide,HEMC inokonakala kwezinto eziphilayo kwaye ngoko inokusebenza okuncomekayo kokusingqongileyo. Inokuthi ithathe indawo yezongezo zekhemikhali ezenziweyo kunye nokunciphisa izinto ezinobungozi kwiingubo, ngaloo ndlela iphucula ukusebenza kokusingqongileyo kweengubo ezisekelwe kwisamente. Kwiingubo zezakhiwo zanamhlanje, ukukhuselwa kwendalo kuye kwaba yinto ekugxilwe kuyo kwiimarike kunye nemimiselo, ngoko ke ukusetyenziswa kwe-HEMC kudlala indima enhle ekuphuculeni ukukhuselwa kokusingqongileyo kweengubo.
8. Ukuphucula ukuqina kwepeyinti
Ukongezwa kwe-HEMC kunokuphucula ukunyanzeliswa kokugqoka, ukuchasana kwemozulu kunye nokuxhatshazwa kwe-UV yeengubo ezisekelwe kwi-samente. Inokucothisa iingxaki ezinjengokubuna kunye nokuqhekeka kweengubo ezenziwe ngesamente ezibangelwa yimiba yangaphandle yendalo efana nokukhanya kwelanga kunye nokhukuliseko lwemvula, kunye nokuphucula ukuqina kwengubo. Olu ncedo lufanelekile ngokukhethekileyo ekwakheni iingubo zangaphandle zodonga ezibonakaliswe kwimeko yangaphandle ixesha elide kwaye linokwandisa ubomi benkonzo yokugqoka.
9. Ukuphucula iimpawu ze-antibacterial ze-cement-based coatings
Njengoko iimfuno zempilo kunye nokhuseleko kwizinto zokwakha ziqhubeka zikhula, iipropati ze-antimicrobial kwi-coatings ziba ngumlinganiselo obalulekileyo. I-HEMC ngokwayo ineempawu ezithile zokulwa ne-antibacterial kwaye inokuthintela ngokufanelekileyo ukukhula kwesikhunta kunye neebhaktheriya kwindawo yokugubungela. Kwindawo enomswakama ophezulu, ukongezwa kwe-HEMC kunokunceda ukugquma ukuxhathisa ukukhukuliseka kwesikhunta kunye nefungi kunye nokuphucula ucoceko kunye nokuqina kwengubo.
10. Ukuphucula ukhuseleko lolwakhiwo lweengubo ezisekelwe kwisamente
Njengekhemikhali engeyiyo inetyhefu kunye nengenabuhlungu, i-HEMC inokhuseleko oluphezulu. Ngexesha lenkqubo yokwakha,HEMCayinabungozi kangako kumzimba womntu kwaye inciphisa impembelelo kwimpilo yabasebenzi bokwakha. Ukongezelela, i-HEMC inokunciphisa ngokufanelekileyo uthuli oluveliswa ngexesha lokwakha, ngaloo ndlela iphucula umgangatho womoya wendawo yokwakha.
Ukusetyenziswa kweihydroxyethyl methylcellulosekwiingubo ezisekelwe kwisamente zineenzuzo ezininzi. Ayinakuphucula kakhulu ukusebenza kokwakhiwa kwengubo, ukwandisa ixesha lokuvula, kunye nokuphucula ukunamathela, kodwa kunye nokuphucula ukuxhathisa ukuqhekeka, ukumelana kwamanzi, i-rheology kunye nokuqina kwengubo. Ukongezelela, i-HEMC, njenge-additive-friendly and non-toxic additive, ayiphuculi kuphela ukusebenza kwengubo, kodwa inceda ukunciphisa umthwalo wokusingqongileyo. Ngoko ke, i-HEMC isetyenziswe ngokubanzi kwiingubo zanamhlanje ezisekelwe kwi-samente kwaye ibe yinto ebalulekileyo ekuphuculeni umgangatho wokugqoka kunye nokusebenza kakuhle kokwakhiwa.
