I-Methyl Hydroxyethyl Cellulose (MHEC) i-thickener kunye ne-adhesive esetyenziswa ngokuqhelekileyo kwizinto zokwakha. Ukuqaliswa kwayo kunempembelelo ebalulekileyo kwiipropati ze-matrix yesamente.
1. Ukuphucula ukuguquguquka kunye nokusebenza
I-Methyl hydroxyethyl cellulose, njenge-thickener, inokuphucula kakhulu ukumanzi kwe-matrix yesamente. Yenza i-sement slurry izinzile kwaye i-fluid ngexesha lenkqubo yokwakha ngokunyusa i-viscosity yomxube. Oku kunceda ukuzalisa iimbumba eziyinkimbinkimbi kunye nokunciphisa i-spatter ngexesha lokwakha. Ukongeza, i-methyl hydroxyethyl cellulose inokunyusa ukugcinwa kwamanzi kwi-matrix yesamente kunye nokunciphisa into yokopha kwe-sement slurry, ngaloo ndlela iphucula umgangatho wokwakha.
2. Ukuphucula ukubambelela
I-Methyl hydroxyethyl cellulose inokuphucula ngokubonakalayo iipropathi zokubopha i-matrix yesamente. Oku kungenxa yokuba ineempawu ezintle zokuncamathelisa kwaye inokudibanisa kunye nokufuma kwisamente ukwenza i-colloid kunye nokunamathela olomeleleyo. Esi siphumo sokuguqulwa sibaluleke kakhulu ekuphuculeni ukunamathela phakathi kwe-matrix ye-samente kunye ne-substrate, ngokukodwa kwi-plastering eludongeni, i-ceramic tile pasting kunye nezinye izicelo.
3. Ichaphazela amandla kunye nokuqina
Ukongezwa kwe-methylhydroxyethylcellulose kunempembelelo ethile kumandla e-matrix yesamente. Ngaphakathi koluhlu oluthile lwedosi, i-methylhydroxyethyl cellulose inokuphucula amandla oxinzelelo kunye namandla okuguquguquka kwe-matrix yesamente. Ngokuphucula ukufana kunye nokuzinza kwe-cement paste, kunciphisa ama-pores kunye nokuqhekeka kwi-matrix ye-samente, ngaloo ndlela iphucula amandla onke kunye nokuqina kwezinto. Nangona kunjalo, ukuba kuninzi kakhulu kufakwe, kunokubangela ukuhla kwe-bond phakathi kwe-samente kunye ne-aggregate kwi-matrix ye-samente, ngaloo ndlela ichaphazela amandla ayo okugqibela.
4. Ukuphucula ukuxhathisa kokuqhekeka kwe-matrix yesamente
Ekubeni i-methylhydroxyethylcellulose inokuphucula ukugcinwa kwamanzi kwi-matrix yesamente, inokunciphisa iintanda ezibangelwa ukomisa kwinqanaba elithile. Ukomisa ukucutheka kwe-matrix yesamente sesinye sezona zizathu ziphambili zokuqhekeka, kwaye i-methylhydroxyethyl cellulose inceda ukunciphisa umngcipheko wokuqhekeka okubangelwa kukomisa ukuncipha ngokunciphisa ukuphuma kwamanzi ngokukhawuleza.
5. Ukulawulwa kwe-Bubble kwi-matrix yesamente
I-Methyl hydroxyethyl cellulose inokwenza isakhiwo se-foam esizinzileyo kwi-matrix ye-samente, enceda ekuphuculeni i-air encapsulation ye-matrix ye-samente. Le propati yokulawula i-bubble yomoya idlala indima ekuphuculeni iimpawu zokugquma kwe-thermal ye-matrix ye-samente kunye nokunciphisa ubuninzi be-matrix ye-samente. Nangona kunjalo, amaqamza amaninzi kakhulu anokubangela ukuba imathiriyeli iphelelwe ngamandla, ngoko ke imali efanelekileyo kufuneka yongezwe ngokusekelwe kwisicelo esithile.
6. Ukuphucula ukungakwazi ukungena
Ngokuphucula ukugcinwa kwamanzi kwi-matrix ye-samente, i-methylhydroxyethylcellulose inokunciphisa ngokufanelekileyo ukunyanzeliswa kwe-matrix ye-samente. Oku kubaluleke kakhulu ekuphuculeni ukungabikho kwamanzi kunye nokusebenza kwamanzi kwi-matrix ye-samente, ngokukodwa kwizicelo ezifuna ukukhuselwa kwamanzi, njengezindlu zangaphantsi, iindonga zangaphandle, njl.
Ukusetyenziswa kwe-methylhydroxyethyl cellulose kwi-matrix ye-samente kunokuzisa ukuphuculwa komsebenzi ohlukeneyo, kubandakanywa nokuphucula umbane, ukuphucula ukunamathela, ukuqinisa amandla, ukuphucula ukuxhathisa ukuqhekeka, ukulawula amaqamza kunye nokuphucula ukunganyanzeki. Nangona kunjalo, ukusetyenziswa kwayo kunye nomlinganiselo kufuneka kuhlengahlengiswe ngokufanelekileyo ngokweemfuno ezithile zesicelo kunye neemfuno zemathiriyeli ukufumana iziphumo ezilungileyo zokusebenza. Ngokudibanisa kunye nokulungiswa kwenzululwazi kunye nokufanelekileyo, i-methyl hydroxyethyl cellulose inokuphucula ngokufanelekileyo ukusebenza ngokubanzi kwe-matrix yesamente kwaye ihlangabezane neemfuno ezahlukeneyo zobunjineli.
