Umsebenzi kunye nokusetyenziswa kwe-cellulose ether kwi-mortar esele ixutywe

I-Cellulose ether inemisebenzi emithathu ilandelayo:

1) Iyakwazi ukujiyisa udaka olutsha ukukhusela ulwahlulo kwaye ufumane umzimba weplastiki ofanayo;

I-2) Inempembelelo yokungenisa umoya, kwaye iyakwazi nokuzinzisa iyunifomu kunye namaqamza omoya amahle angeniswa kumdaka;

I-3) Njenge-agent egcina amanzi, inceda ukugcina amanzi (amanzi akhululekile) kwi-meat-layer mortar, ukwenzela ukuba i-samente ibe nexesha elingakumbi lokukhupha emva kokuba udaka lwakhiwe.

Kwi-dry-mixed mortar, i-methyl cellulose ether idlala indima yokugcina amanzi, ukuqina kunye nokuphucula ukusebenza kokwakhiwa.Ukusebenza kakuhle kogcino lwamanzi kuqinisekisa ukuba udaka aluyi kubangela isanti, umgubo kunye nokunciphisa amandla ngenxa yokunqongophala kwamanzi kunye ne-cement hydration engaphelelanga;umphumo wokuqina uphucula kakhulu amandla okwakhiwa kodaka olumanzi, kunye nobuchule obuhle bokuchasana nokunamathela kwi-tile ngumzekelo;Ukongezwa kwe-base cellulose ether kunokuphucula kakhulu i-viscosity emanzi yodaka olumanzi, kwaye ibe ne-viscosity efanelekileyo kwii-substrates ezahlukeneyo, ngaloo ndlela iphucula ukusebenza kodonga lodaka olumanzi kunye nokunciphisa inkunkuma.

Xa usebenzisa i-cellulose ether, kufuneka kuqatshelwe ukuba i-dosage iphezulu kakhulu okanye i-viscosity iphezulu kakhulu, imfuno yamanzi iya kwanda, kwaye ukwakhiwa kuya kuziva kunzima (i-sticky trowel) kunye nokusebenza kuya kuncipha.I-ether ye-cellulose iya kulibazisa ixesha lokumisela isamente, ngakumbi xa umxholo uphezulu, umphumo wokubuyisela ubaluleke kakhulu.Ukongeza, i-cellulose ether iya kuchaphazela ixesha elivulekileyo, ukuxhathisa kwe-sag kunye namandla ebhondi yodaka.

I-ether ye-cellulose efanelekileyo kufuneka ikhethwe kwiimveliso ezahlukeneyo, kwaye imisebenzi yayo ihluke.Ngokomzekelo, kuyacetyiswa ukuba ukhethe i-MC ene-viscosity ephezulu kwi-adhesive tile, enokwandisa ixesha lokuvula kunye nexesha lokulungelelanisa, kunye nokuphucula ukusebenza kwe-anti-slip;kwi-self-leveling mortar, kuyacetyiswa ukuba ukhethe i-MC kunye ne-viscosity ephantsi ukugcina i-fluidity of mortar, kwaye kwangaxeshanye Iphinda isebenze ukukhusela i-stratification kunye nokugcinwa kwamanzi.I-ethers ye-cellulose efanelekileyo kufuneka imiselwe ngokweengcebiso zomenzi kunye neziphumo zovavanyo ezihambelanayo.

Ukongeza, i-cellulose ether inefuthe lokuzinzisa i-foam, kwaye ngenxa yokubunjwa kwefilimu kwangaphambili, kuya kubangela ukukhupha ulusu kumdaka.Ezi filim ze-cellulose ether zisenokuba zenzekile ngexesha okanye ngokukhawuleza emva kokuzamiswa, phambi kokuba umgubo werabha odispersible uqalise ukwenza ifilimu.Undoqo emva kwesi siganeko ngumsebenzi ongaphezulu we-cellulose ethers.Ekubeni amaqamza omoya angeniswa ngokwasemzimbeni yi-agitator, i-cellulose ether ngokukhawuleza ithatha ujongano phakathi kwamaqamza omoya kunye nodaka lwesamente ukwenza ifilimu.Iimbumba zazisemanzi kwaye ngaloo ndlela ziguquguquka kakhulu kwaye zicinezelekile, kodwa umphumo we-polarization waqinisekisa ngokucacileyo ukulungelelaniswa kocwangco lweeathomu zabo.

Ekubeni i-cellulose ether iyipolymer enyibilikayo emanzini, iya kufudukela kumphezulu wodaka oludibanisa nomoya kunye nokunyuka kwamanzi kumdaka omtsha ukwenza ubutyebi, ngaloo ndlela kubangele ukukhutshwa kwe-cellulose ether kumphezulu wodaka olutsha.Njengomphumo wesikhumba, ifilimu ye-denser yenziwa phezu komdaka, onciphisa ixesha elivulekileyo lomdaka.Ukuba iithayile zincanyathiselwe kumphezulu wodaka ngeli xesha, lo maleko wefilimu nawo uya kusasazwa ngaphakathi kodaka kunye nojongano phakathi kweethayile kunye nodaka, ngaloo ndlela kuncitshiswe amandla okudibanisa kamva.Ukukhutshwa kwe-ether ye-cellulose kunokuncitshiswa ngokulungelelanisa ifomula, ukukhetha i-ether ye-cellulose efanelekileyo kunye nokongeza ezinye izongezo.
