Izinto Ezichaphazela I-Cellulose Ether Kwi-Cement Mortar

Ii-cellulose ethers zidlala indima ebalulekileyo ekuphembeleleni iimpawu ze-samente mortar, zichaphazela ukusebenza kwayo, ukunamathela kwayo, ukugcinwa kwamanzi, kunye namandla oomatshini. Izinto ezininzi zinokuchaphazela ukusebenza kwee-cellulose ethers kwi-samente mortar:

1. Ulwakhiwo lweeKhemikhali: Ulwakhiwo lweekhemikhali ze-cellulose ethers, kubandakanya inqanaba lokutshintshwa (DS) kunye nohlobo lwamaqela asebenzayo (umz., i-methyl, i-ethyl, i-hydroxypropyl), luchaphazela kakhulu indlela ezisebenza ngayo kwi-samente mortar. I-DS ephezulu kunye neentlobo ezithile zamaqela asebenzayo zinokuphucula ukugcinwa kwamanzi, ukunamathela, kunye neempawu zokutyeba.
2. Ubungakanani kunye nokuSasazwa kweeParticle: Ubungakanani beeparticle kunye nokuSasazwa kwee-cellulose ethers kunokuchaphazela ukusasazeka kwazo kunye nokusebenzisana kwazo neeparticles zesamente. Iiparticles ezintle ezinokusasazwa okufanayo zihlala zisasazeka ngempumelelo kwi-mortar matrix, nto leyo ekhokelela ekuphuculweni kokugcinwa kwamanzi kunye nokusebenza kakuhle.
3. Umlinganiselo: Umlinganiselo wee-ether ze-cellulose kwi-metal yesamente uchaphazela ngqo ukusebenza kwazo. Amanqanaba omlinganiselo afanelekileyo amiselwa ngokusekelwe kwizinto ezifana nokusebenza okufunekayo, iimfuno zokugcina amanzi, kunye namandla oomatshini. Umlinganiselo ogqithisileyo unokukhokelela ekuqineni okugqithisileyo okanye ekubambezelekeni kwexesha lokubeka.
4. Inkqubo Yokuxuba: Inkqubo yokuxuba, kuquka ixesha lokuxuba, isantya sokuxuba, kunye nokulandelelana kokongeza izithako, inokuchaphazela ukusasazeka kunye nokufuma kwe-cellulose ethers kwi-samente mortar. Ukuxuba ngokufanelekileyo kuqinisekisa ukusasazwa okufanayo kwe-cellulose ethers kuyo yonke i-mortar matrix, kuphucula ukusebenza kwazo ekuphuculeni ukusebenza kunye nokunamathela.
5. Ulwakhiwo lweSamente: Uhlobo kunye nolwakhiwo lwesamente esetyenziswa kwimilo yesamente kunokuchaphazela ukuhambelana kunye nokusebenza kwee-ether ze-cellulose. Iintlobo ezahlukeneyo zesamente (umz., isamente yasePortland, isamente exutyiweyo) zinokubonisa ukusebenzisana okwahlukeneyo nee-ether ze-cellulose, nto leyo echaphazela iimpawu ezifana nexesha lokubeka, uphuhliso lwamandla, kunye nokuqina.
6. Iimpawu zeAggregate: Iimpawu zeaggregate (umz., ubungakanani besuntswana, imilo, ubume bomphezulu) zinokuchaphazela ukusebenza kwee-cellulose ethers kwi-mortar. Ii-aggregate ezineendawo ezirhabaxa okanye iimilo ezingacwangciswanga zinokubonelela ngonxibelelwano olungcono lwe-mechanical kunye nee-cellulose ethers, nto leyo ephucula ukunamathelana kunye nokuhlangana kwi-mortar.
7. Iimeko Zendalo: Izinto ezikwindalo ezifana nobushushu, ukufuma, kunye neemeko zokuphilisa zinokuchaphazela ukufuma kunye nokusebenza kwee-cellulose ethers kwi-samente mortar. Amanqanaba obushushu okanye ukufuma agqithisileyo anokutshintsha ixesha lokuseta, ukusebenza, kunye neempawu zoomatshini ze-mortar equlethe ii-cellulose ethers.
8. Ukongezwa kwezinye izongezo: Ukubakho kwezinye izongezo, ezifana nee-superplasticizers, ii-air-entraining agents, okanye ii-accelerators ezibekwe, zinokusebenzisana nee-cellulose ethers kwaye zichaphazele ukusebenza kwazo kwi-samente mortar. Uvavanyo lokuhambelana kufuneka lwenziwe ukuze kuvavanywe iziphumo ezihambelanayo okanye ezichaseneyo zokudibanisa ii-cellulose ethers nezinye izongezo.

Ukuqonda izinto ezichaphazela ii-cellulose ethers kwi-samente mortar kubalulekile ekwenzeni ngcono iifomyula ze-mortar kunye nokufezekisa iipropati ezinqwenelekayo ezifana nokusebenza ngcono, ukugcinwa kwamanzi, kunye namandla oomatshini. Ukwenza uvavanyo olucokisekileyo kunye novavanyo kunokunceda ekuchongeni iimveliso ze-cellulose ether ezifanelekileyo kunye namanqanaba omthamo kwizicelo ezithile ze-mortar.
