Mataira anonamira anoshandiswa zvakanyanya mumabasa ekuvaka emazuva ano. Basa ravo guru nderekunamatira zvakasimba matiles panzvimbo yekuvaka kuti ave nechokwadi chokuti matairi haazodonha kana kushanduka. Cellulose ether, sechinhu chinowedzera chinowedzera, chinoshandiswa zvakanyanya mumatairi ekunamatira kuvandudza kushanda kwavo.
Basic components of tile adhesive
Mataira anonamira kazhinji anoumbwa nesamende, jecha, cellulose ether, glue poda uye zvimwe zvinowedzera. Simende inoshandiswa sechinhu chikuru chinosunga kuti chipe simba renheyo; jecha rinoshandiswa sekuzadza kuwedzera huwandu uye kuderedza shrinkage; cellulose ether uye rubber powder inoshandiswa semagadzirirwo ekuvandudza kushanda kwekushanda uye maitiro emuviri wekunamatira.
Basa re cellulose ethers
Cellulose ether musanganiswa wepolymer wakatorwa kubva kune yakasikwa cellulose. Mabasa ayo makuru ndeaya:
Kuchengetwa kwemvura: Cellulose ether inogona kuvandudza zvakanyanya simba rekuchengetedza mvura yekeramic tile adhesives uye kuderedza kubuda kwemvura, nekudaro kuve nechokwadi chekuti hydration yakakwana yesimende uye kuvandudza simba.
Kuomesa mhedzisiro: Cellulose ether inoita kuti kunamira kuve kwakanaka thixotropy uye kutsvedza kuramba, iyo inofambisa kuvaka uye inovandudza chisungo mhedzisiro.
Kuvandudza kushanda kwekushanda: Cellulose ether inogona kuita kuti kunamira kuve nyore uye kuve nyore kushanda panguva yekuvaka, kuvandudza kugona kwekuvaka uye kunaka.
Mhedzisiro ye cellulose ether zvirimo pakuita kweceramic tile adhesives
Kuchengetwa kwemvura: kuwedzera zvinyorwa zve cellulose ether kuchavandudza zvakanyanya kuchengetwa kwemvura kwekunamatira. Munguva ye simenti hydration process, kuchengetwa kwemvura kwakakosha pakuita kuti simende iwane mvura yakakwana. Iyo yakakwirira iyo dhigirii ye hydration, iyo yakawanda hydration zvigadzirwa zvinogadzirwa ne simenti uye kukwira kwesimba rebhondi. Naizvozvo, huwandu hwakakodzera hweselulosi ether hunobatsira kuvandudza kusimba uye kusimba kwekunamatira.
Simba rekubatanidza: Sezvo iyo cellulose ether yemukati inowedzera, iyo yekubatanidza simba rekunamatira ichawedzera zvakanyanya. Izvi zvinodaro nekuti kuchengetwa kwemvura uye kukora mhedzisiro ye cellulose ether inobvumira kunamira kuti ipinde zvirinani mukati meiyo ceramic mataira uye substrates, ichivandudza iyo interface bonding effect. Nekudaro, yakawandisa yemukati ye cellulose ether inotungamira kune yakawandisa viscosity, inokanganisa kushanda, uye inogona kutokonzera kutsemuka mukunamira panguva yekuomesa, izvo zvinozoderedza kusimba kwekubatanidza.
Kushanda: Cellulose ether ine simba guru pakushanda kwezvinonamira. Huwandu hwakakodzera hweselulosi ether hunogona kuita kuti kunamira kuve nyore kuisa uye kugadzirisa panguva yekuvaka, kuderedza kutsvedza kwematairi eceramic, nekuvandudza kugona kwekuvaka. Yakanyanya kuderera cellulose ether content ichaita kuti kunamira kuve nekusakwana viscosity uye kutsvedza nyore; nepo yakawandisa cellulose ether yemukati ichaita kuti inonamira yanyanya viscous uye yakaoma kugadzira.
Slip kuramba: Kuvakwa kwemadziro mataira, kutsvedza kuramba chiratidzo chakakosha. Cellulose ether inogona kuvandudza zvakanyanya anti-slip performance yeadhesive, kuve nechokwadi chekuti matiles haazotsvedza pasi mushure mekunamatwa. Tsvagiridzo inoratidza kuti huwandu hwakakodzera hweselulosi ether hunogona kuvandudza zvakanyanya anti-kutsvedza kugona kweanonamira, nepo yakawandisa cellulose ether ichaita kuti kuvaka kuome nekuti kuyerera kweinamira kwakadzikira.
Maedzo uye Analysis
Kuti uongorore maitiro eiyo cellulose ether zvirimo pakuita kweceramic tile adhesives, zvinotevera zviedzo zvinogona kuitwa:
Zvishandiso zvekuyedza: Shandisa mhando imwechete uye modhi yesimende, jecha, nehupfu yerabha, uye wedzera zvakasiyana zviri mukati meselulosi ether (senge 0.1%, 0.2%, 0.3%, 0.4%, 0.5%).
Nzira dzekuedza:
Muedzo wekuchengetedza mvura: Edza simba rekuchengetedza mvura yeadhesive pasi pezvakasiyana cellulose ether zviri mukati kuburikidza nesefa bepa rekunyudza mvura nzira.
Kuedzwa kwesimba reBonding: Zvinoenderana neiyo yenyika chiyero nzira, kusimba kwekubatana kweanonamira pasi pezvakasiyana cellulose ether zviri mukati inoedzwa.
Constructability bvunzo: Ongorora kureruka kwekushandisa uye kutsvedza kuramba kweadhesive kuburikidza nekuita kwekuvaka chaiko.
Ongororo yedata: Ongorora data rekuyedza, dhirowa hukama pakati peselulosi ether zvirimo uye zviratidzo zvekuita sekuchengetedza mvura, kusimba kwekubatanidza, uye kushanda kuti uwane yakakwana cellulose ether yemukati renji.
Cellulose ether content ine simba guru pakuchengetedza mvura, simba rekubatanidza uye kushanda kwematairi e ceramic adhesives.
Nhamba yakakodzera ye cellulose ether inogona kuvandudza zvakanyanya kushanda kweadhesive, asi yakawandisa zvinyorwa zve cellulose ether zvinotungamira kune yakawandisa viscosity yekunamatira, inokanganisa kushanda uye kusungirira mhedzisiro.
Kuburikidza nekuyedza dhata kuongororwa, iyo yakakwana cellulose ether yemukati renji inogona kutariswa kuti iwane yakakwana chiyero cheanonamira zvivakwa.
Kudzora kunonzwisisika kwehuwandu hwekuwedzera kwe cellulose ether ndiyo kiyi yekuvandudza mashandiro eceramic tile adhesives. Tsvagiridzo yeramangwana inogona kuenderera mberi nekuongorora mhedzisiro yemhando dzakasiyana dze cellulose ethers pane adhesive zvivakwa kuti igadzire yakakwirira performance tile inonamira zvigadzirwa.
