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 yenziwa ikakhulu yi-hydrogen bond phakathi kwe-cellulose ether molekyuli kunye ne-molecule yamanzi kunye nesenzo sokujija se-cellulose ether molekyuli, eneneni, ithatha inxalenye yebhondi ye-hydrogen kwi-cellulose ether molecular chain kwaye yenza buthathaka ukubanjiswa kwe-cellulose ether, eyenza buthathaka ugcino lwamanzi kunye nokukwazi ukumanzisa kwe-cellulose ether. abavelisi udaka ubukhulu becala abaziva le ngongoma, kwelinye icala, iimveliso zodaka lwasekhaya zisenjalo rhabaxa ngokwentelekiso, abakakulungeli ukunikela ingqalelo kwinqanaba yokusebenza yokusebenza, kwelinye icala, sikhetha viscosity iphezulu kakhulu. kunobuchwephesha obufunekayo be-viscosity, le nxalenye iphinde ihlawule ukulahleka kokugcinwa 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 sokwakheka kwefilimu ye-cellulose ether kunye nemeko yefilimu, ngaloo ndlela ichaphazela indima ye-cellulose ether kumdaka, ngokuthe ngqo- impembelelo yokujonga yile: amandla okuncamathela okuxinana atshintshile phantsi kwemeko nganye yokunyanga; ixesha lokumisa udaka liyongeziwe.
1.Ngaphantsi kwemeko yokunyanga esemgangathweni, ukongezwa kwe-tackifier kunye ne-cellulose ether ngaphandle kwe-tackifier kwinkqubo yokuvelisa kunempembelelo ethile kumandla okunamathela kwi-tile ye-ceramic enamathelayo, iimveliso ezongezwe nge-tackifier kwinkqubo yokuvelisa zinamandla aphezulu okunamathela. .
2. Kwinkalo yokumelana namanzi, amandla okubambelela kwithayile ye-ceramic adhesive kunye ne-cellulose ether eyongezelelweyo i-tackifier kwinkqubo yokuvelisa imbi kakhulu kunemveliso ngaphandle kwe-tackifier kwinkqubo yokuvelisa eqhelekileyo, i-cellulose ether equkethe i-tackifier ichaphazela amanzi. ukuchasana kwe-adhesive tile.
3. Ngokwexesha lokusetha 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, isenzo sokudibanisa i-cross-link esenza ukuba isisombululo se-cellulose ether yamanzi sibe nesithintelo esiphezulu se-steric, esiboniswa siphezulu kuvavanyo, kodwa ubukho be-tackifier buchaphazela iipropati ezininzi ezibalulekileyo zesicelo se-cellulose. I-ether, njengokumelana kwamanzi, ixesha lokuvula, ukumanzi kunye nokunye. 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 abavelisi bodaka banikela ingqalelo kakhulu kwi-viscosity, ebangela ukuba amanye amashishini emveliso ye-cellulose ether anyuse i-viscosity ngokusebenzisa izinto ezongezelelweyo ukuhlangabezana neemfuno zabenzi bodaka, kwaye olu hlobo lweemveliso lune-viscosity ephezulu ebonakalayo, ngokubanzi. ukusebenza kufanelekile ukuhoywa kwabasebenzisi, kwaye i-viscosity ephezulu ebonakalayo eyenziwe ngokunyuka kwe-viscosity ayinakufezekisa ithiyori "ye-viscosity ephezulu ephantsi" ithiyori elindelwe ngabavelisi bodaka, 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.
