I-cellulose ethers, ngakumbi i-hypromellose ethers, zizinto ezibalulekileyo zodaka lwezorhwebo. Kwi-cellulose ether, i-viscosity yayo isalathiso esibalulekileyo samashishini okuvelisa udaka, i-viscosity ephezulu iphantse ibe yimfuno esisiseko yoshishino lodaka. Ngenxa yempembelelo yetekhnoloji, inkqubo kunye nezixhobo, kunzima ukuqinisekisa i-viscosity ephezulu yasekhayai-cellulose etheriimveliso ixesha elide. I-ether ye-cellulose isetyenziswe njenge-agent egcina amanzi, i-thickener kunye ne-binder kwiimveliso zodaka, ezinempembelelo enkulu ekusebenzeni komsebenzi, i-viscosity emanzi, ixesha lokusebenza kunye nemodi yokwakha yenkqubo yodaka. Le misebenzi ifezekiswa ikakhulu yi-hydrogen bond phakathi kwe-cellulose ether molekyuli kunye ne-molecule yamanzi kunye nesenzo sokujija se-cellulose ether molekyuli, enyanisweni, ithatha inxalenye yebhondi ye-hydrogen kwikhonkco ye-cellulose ye-ether ye-molecular kwaye yenza buthathaka ukuphonswa kwe-ether cellulose, eyenza buthathaka ukugcinwa kwamanzi kunye nokukwazi ukumanzisa kwe-cellulosether. abenzi udaka ubukhulu becala musa bazive le ngongoma, kwelinye icala, iimveliso zodaka lwasekhaya kusekho rhabaxa ngokwentelekiso, abakhange balumkele ingqalelo kwinqanaba ukusebenza ukusebenza, kwelinye icala, sikhetha viscosity iphezulu kakhulu kunobugcisa efunekayo viscosity, le nxalenye kwakhona imbuyekezo ilahleko nokugcinwa kwamanzi, kodwa kwi wettability yonakele.
Ukusebenza kodaka kuphenjelelwa yi-cellulose ether equkethe i-adhesive extractant kwinkqubo yokuvelisa, kweli phepha, umahluko wamandla okunamathela obunzima phakathi kwemveliso ye-cellulose kunye nemveliso ye-cellulose ether eyongeziweyo nge-tackifier kwi-adhesive tile adhesive yaqinisekiswa yizilingo. I-Tackifier luhlobo lwemathiriyeli eyongezwe ngabavelisi be-cellulose ether ukuze benze ukusilela kobugcisa bokuvelisa, itekhnoloji kunye nezixhobo. Ubukho be-tackifier benza iimolekyuli zekhonkco elide le-cellulose ether cross-link kwaye ibe yi-net-like, echaphazela isantya sokubunjwa kwefilimu ye-cellulose ether kunye nemeko yefilimu, ngaloo ndlela ichaphazela indima ye-cellulose ether kwi-mortar, impembelelo yokujonga ngokuthe ngqo yile: amandla okunamathela atshintshileyo atshintshile phantsi kwemeko nganye yokunyanga; ixesha lokumisa udaka liyongeziwe.
I-1.Ngaphantsi kwemeko yonyango esemgangathweni, ukongezwa kwe-tackifier kunye ne-cellulose ether ngaphandle kwe-tackifier kwinkqubo yokuvelisa kunempembelelo ethile kumandla okunamathela kwi-tile ye-ceramic adhesive, iimveliso ezongeziweyo nge-tackifier kwinkqubo yokuvelisa zinamandla aphezulu okubambelela.
I-2.Kumba wokumelana nokumelana namanzi, amandla okubambelela kwi-tile ye-ceramic adhesive kunye ne-cellulose ether eyongeziweyo i-tackifier kwinkqubo yokuvelisa imbi kakhulu kunemveliso ngaphandle kwe-tackifier kwinkqubo yokuvelisa eqhelekileyo, i-cellulose ether equkethe i-tackifier ichaphazela ukuxhathisa kwamanzi kwi-adhesive tile.
3. Ngokwexesha lokuseta umoya,i-cellulose etherkunye ne-tackifier yayisetyenziswe kwi-adhesive ye-tile, amandla ayo okubambelela angaphantsi kwemveliso ngaphandle kwe-tackifier, kwaye ixesha lokuvula lalifutshane.
4.Ngokubhekiselele kwixesha lokumisela, isantya sokunyanga se-cellulose ether ceramic tile adhesive ngaphandle kokongeza i-tackifier phantsi kwenkqubo eqhelekileyo yokuvelisa ngokukhawuleza. Isishwankathelo, ubukho be-tackifier, i-cross-linking action eyenza i-cellulose ether isisombululo samanzi sibe nesithintelo esiphezulu se-steric, esiboniswa ukuba siphezulu kuvavanyo, kodwa ubukho be-tackifier buchaphazela iimpawu ezininzi zesicelo esibalulekileyo se-cellulose ether, ezifana nokuchasana kwamanzi, ixesha lokuvula, ukumanzisa njalo njalo. Enyanisweni, i-viscosity enye kuphela yezalathisi zokusebenza ze-cellulose ether, i-viscosity ayiyona isalathiso esibalulekileyo kwintsebenzo ebanzi ye-cellulose ether, kodwa uhlobo kunye nomxholo wamaqela kufuneka ube ingqwalasela yabenzi bodaka.
5.Kukwangenxa yokuba abenzi bodaka banikela ingqalelo kakhulu kwi-viscosity, nto leyo ebangela ukuba amashishini emveliso ye-cellulose ether anyuse i-viscosity ngokusebenzisa izinto ezongezelelweyo ukuhlangabezana neemfuno zabenzi bodaka, kwaye olu hlobo lweemveliso lune-viscosity ephezulu ebonakalayo, ukusebenza kwayo okubanzi kufanelekile ukuqwalaselwa kwabasebenzisi, kunye nokubonakala okubonakalayo okuphezulu kwe-viscosity ephezulu kunokwandisa i-viscosity ephantsi. abavelisi bodaka balindele, kodwa ayikho enyanisweni. Ukuze ukhethe i-cellulose ether, eyona nto ibalulekileyo ekrwada kwidaka, amashishini omdaka alandela umgangatho ophezulu kunye nozinzile kufuneka azi ulwazi oluthile emva, oku kuya kuba luncedo kubavelisi ukuphuhlisa iimveliso eziphezulu, ukuqinisekisa ukuzinza komgangatho wemveliso.
