Impembelelo ye-cellulose ether ekusebenzeni kwe-self-leveling mortar

I-self-leveling mortar inokuxhomekeka kubunzima bayo ukwenza isiseko esisicaba, esithambileyo kunye nesiqinileyo kwi-substrate yokubeka okanye ukudibanisa ezinye izinto, kwaye kwangaxeshanye inokuqhuba ukwakhiwa okukhulu kunye nokusebenza kakuhle. Ke ngoko, ulwelo oluphezulu ngumba obaluleke kakhulu wodaka lokuzilinganisa. Ukongezelela, kufuneka kube nokugcinwa kwamanzi athile kunye namandla okudibanisa, akukho nto yokwahlulwa kwamanzi, kwaye ibe neempawu zokufudumeza ukushisa kunye nokunyuka kweqondo lokushisa eliphantsi.

Ngokuqhelekileyo, udaka lokuzilinganisa lufuna ukuguquguquka okulungileyo, kodwa ukuguquguquka kweyona nto ye-samente intlama idla ngokuba yi-10-12cm kuphela; I-cellulose ether iyona nto yokudibanisa i-mortar edibeneyo edibeneyo, nangona isixa sokongeza siphantsi kakhulu, sinokuphucula kakhulu ukusebenza kwe-Mortar, inokuphucula ukuhambelana, ukusebenza okusebenzayo, ukusebenza kwebhondi kunye nokugcinwa kwamanzi omdaka. Idlala indima ebaluleke kakhulu kwintsimi yodaka olulungeleyo.

1. Ukushukuma

I-ether ye-cellulose inempembelelo ebalulekileyo ekugcinweni kwamanzi, ukuhambelana kunye nokusebenza kokwakhiwa kwe-self-leveling mortar. Ngokukodwa njengodaka lokuzilinganisa, ukumanzi sesinye sezibonakaliso eziphambili zokuvavanya ukusebenza kokuzilinganisa. Ngaphantsi kwesiseko sokuqinisekisa ukubunjwa okuqhelekileyo kodaka, ukunyanzeliswa kodaka kunokulungiswa ngokutshintsha inani le-cellulose ether. Nangona kunjalo, ukuba idosi iphezulu kakhulu, i-fluidity ye-mortar iya kuncitshiswa, ngoko ke idosi ye-cellulose ether kufuneka ilawulwe ngaphakathi koluhlu olufanelekileyo.

2. Ukugcinwa kwamanzi

Ukugcinwa kwamanzi kwi-mortar yisalathiso esibalulekileyo sokulinganisa ukuzinza kwamacandelo angaphakathi kwi-sand mortar ye-cement. Ukuze ufezekise ngokupheleleyo ukuphendulwa kwe-hydration yezinto ze-gel, isixa esifanelekileyo se-cellulose ether sinokugcina umswakama kwi-mortar ixesha elide. Ngokuqhelekileyo, izinga lokugcinwa kwamanzi kwi-slurry liyenyuka ngokunyuka kwe-cellulose ether content. Ukugcinwa kwamanzi kwi-ether ye-cellulose kunokuthintela i-substrate ekufunxeni amanzi amaninzi ngokukhawuleza, kwaye ithintele ukuphuphuma kwamanzi, ukuze kuqinisekiswe ukuba indawo yodaka inika amanzi aneleyo kwi-samente hydration. Ukongezelela, i-viscosity ye-cellulose ether nayo inempembelelo enkulu ekugcinweni kwamanzi omdaka. Ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi. Ngokuqhelekileyo, i-cellulose ether ene-viscosity ye-400mpa.s isetyenziswa kakhulu kwi-self-leveling mortar, enokuthi iphucule ukusebenza komgangatho wodaka kunye nokwandisa ukuqina kodaka.

3. Ukumisela ixesha

I-ether ye-cellulose inesiphumo esithile sokunciphisa udaka. Ngokunyuka komxholo we-cellulose ether, ixesha lokumisela lomdaka lithatha ixesha elide. Isiphumo esibambekayo se-cellulose etere kwintlama yesamente ixhomekeke ikakhulu kwiqondo lokuthatha indawo yeqela le-alkyl, kwaye ayinanto yakwenza nobunzima bayo bemolekyuli. Incinci iqondo lokutshintshwa kwe-alkyl, ubukhulu bomxholo we-hydroxyl, kunye nesiphumo esicacileyo esicacileyo. Kwaye okukhona uphezulu umxholo we-cellulose ether, kokukhona kubonakala ngakumbi isiphumo sokulibaziseka somaleko wefilimu entsonkothileyo kwi-hydration yokuqala yesamente, ngoko ke isiphumo sokubambezela sikwabonakala ngakumbi.

4. Amandla e-Flexural kunye namandla oxinzelelo

Ngokuqhelekileyo, amandla yenye yezalathisi ezibalulekileyo zovavanyo lwesiphumo sokuphilisa sesamente esekwe kwimathiriyeli yesamente kumxube. Xa umxholo we-cellulose ether ukhula, amandla oxinzelelo kunye namandla okuguquguquka kodaka luya kuncipha.

5. Amandla ebhondi

I-ether ye-cellulose inempembelelo enkulu ekusebenzeni kokubambisana kodaka. I-cellulose ether yenza ifilimu ye-polymer enefuthe lokutywinwa phakathi kweengqungquthela ze-sement hydration kwinkqubo yesigaba se-liquid, ekhuthaza amanzi amaninzi kwifilimu ye-polymer ngaphandle kweengqungquthela ze-cement, ezihambelana nokuhanjiswa okupheleleyo kwe-cement, ngaloo ndlela kuphuculwe ibhondi. amandla entlama emva kokuqina. Kwangaxeshanye, isixa esifanelekileyo se-ether ye-cellulose siphucula iplastiki kunye nokuguquguquka kodaka, kunciphisa ukuqina kwendawo yokutshintsha phakathi kodaka kunye ne-interface ye-substrate, kunye nokunciphisa ukukwazi ukutyibilika phakathi kwe-interfaces. Ukuya kumlinganiselo othile, impembelelo yokudibanisa phakathi kodaka kunye ne-substrate iphuculwe. Ukongezelela, ngenxa yobukho be-cellulose ether kwi-sement paste, indawo ekhethekileyo yokutshintshwa kwendawo kunye ne-interface layer yenziwa phakathi kweengqungquthela zodaka kunye nemveliso ye-hydration. Olu jongano lojongano lwenza ummandla wotshintsho ubhetyebhetye kwaye ungaqini kancinci, ngoko ke, ukuze udaka lube namandla ebhondi eyomeleleyo.
