Mataira anonamira anoita basa rakakosha muindasitiri yekuvaka nekuda kwekugona kwavo kuchengetedza mataira kunzvimbo dzakasiyana siyana, kusanganisira madziro, pasi, uye countertops. Kuitwa kwekunamira kunotarirwa nezvinhu zvakaita sesimba rayo, kusimba, kuramba kwemvura uye kusungirira zvinhu. Nokufamba kwenguva, zvinowedzera kukosha kuvandudza kushanda kwematairi ekunamatira kuti asangane nezvinodiwa zvekuvaka kwemazuva ano. Imwe nzira yekuita izvi ndeye kushandisa cellulose ethers.
Cellulose ethers ikirasi yezvakagadzirwa organic zvinotorwa kubva kune cellulose, yakasikwa polymer inowanikwa mumadziro emadziro ezvirimwa zvese. Aya makomisheni ane hydrophilic, anonyungudika mumvura, uye akanyanya kushanda. Ivo vane huwandu hwakasiyana hwekushandisa mumaindasitiri akasiyana siyana, anosanganisira ekuvaka, emishonga, machira uye zvigadzirwa zvekuchengeta munhu.
Kuwedzera cellulose ethers kumatairi anonamira kunogona kuwedzera kunamira kweanonamira uye akabatana zvivakwa, nekudaro zvichiwedzera kushanda kwayo. Hedzino dzimwe nzira dze cellulose ether dzinovandudza mashandiro ematairi anonamira:
Wedzera kuchengetwa kwemvura
Chinhu chakakosha chekunamatira mataira ndiko kuchengetedza mvura. Tile inonamira inoda kuchengetedza kuenderana kwayo uye kushanda kwayo kana yaiswa mumvura. Izvi zvinodaro nekuti mvura inogona kukanganisa zvakanyanya kunaka kwekunamatira. Kana ma cellulose ether awedzerwa kune matiles adhesive formulations, anowedzera kunamira kwemvura inobata simba.
Cellulose ethers inoshanda semvura-inonyungudika mapolima anotora mvura uye anogadzira chinhu chakafanana nejeli. Iyi gel-yakaita sechinhu inogovera mvura zvakaenzana mukati memusanganiswa wekunamira, kuve nechokwadi chekunamatira kunoramba kuchishandiswa kwenguva refu. Ichi chimiro chinowedzerawo nguva yakavhurika yekunamatira, ichibvumira nguva yakakwana yekuti tile igadzirise isati yakanamatira yaoma.
Kuvandudza chisungo simba
Kusimba kwechisungo chekunamatira tile ndicho chimwe chinhu chakakosha chinotarisa kushanda kwekunamatira. Bond simba zvinoreva simba rinodiwa kutyora chisungo chiri pakati penamira ne substrate. Apo simba rezvisungo rakakwirira, iyo yakanamatira inopesana nekushungurudzika uye deformation, kuve nechokwadi chokuti tile inonamatira zvakasimba kune substrate.
Cellulose ethers inogona kuvandudza simba rekubatanidza rematairi anonamira nekuwedzera kusungirirwa kwezvinhu zvekunamatira. Izvo zvakanamatira zvimiro zvekunamatira zvinogadziriswa nekukwanisa kwayo kunamatira kumusoro kwe substrate. Kana ma cellulose ether awedzerwa kumatairi anonamira maumbirwo, anogadzira nzvimbo inonamira iyo inonamira iyo inonamira inobata zvimiro.
Wedzera kushanduka
Flexibility chinhu chakakosha chekunamatira mataira, kunyanya kana uchigadzirisa mataira kune substrates anoona kuwedzera kwekupisa uye kuderera. Masubstrates akadai sekongiri nehuni anogona kukanganisa zvakanyanya nekuda kwekushanduka kwetembiricha, zvichikonzera kutsemuka kwematairi uye zvinonamira.
Cellulose ethers inogona kuita seplasticizers kuti iwedzere kusimba kweanonamatira, nekudaro ichivandudza kuchinjika kwematairi e ceramic adhesives. Plasticizers makomisheni anowedzera kuchinjika kwezvinhu kuburikidza nekudzikisa intermolecular masimba anobata mamorekuru pamwechete. Kana cellulose ethers yawedzerwa kune mataira adhesive formulations, anoita seplasticizers, zvichiita kuti kunamira kusaite brittle uye kuwedzera elasticity yayo. Ichi chivakwa chinosimudzira kugona kweanonamira kutsungirira kushushikana uye deformation, kuve nechokwadi chekuti mataira anonamira zvakasimba kune substrate.
Vandudza kushanda
Iko kushandiswa kwekushanda kwematairi adhesives hunhu hunokosha hunosarudza kusununguka kwekushandiswa kwekunamatira panguva yekushandiswa. Paunenge uchishandisa tile yekunamatira, musanganiswa wekunamatira unofanirwa kuve neiyo chaiyo kuenderana, viscosity uye kuyerera maitiro. Izvi zvinogonesa kuti kunamatira kugovaniswa zvakaenzana pane substrate, zvichiita kuti mataira aenderane zvakanaka.
Cellulose ethers inogona kuita seyakakora uye rheology modifiers kuvandudza kushanda kwematairi anonamira. Makomisheni anowedzera viscosity yemhinduro, nepo rheology modifiers ari makomisheni anoshandura mafambiro emvura. Kana cellulose ethers ichiwedzerwa kune tile yekunamatira maumbirwo, inowedzera viscosity yemusanganiswa wekunamatira, kuve nechokwadi kuti iyo yakanamatira inopararira zvakaenzana pamusoro pe substrate. Ichi chivakwa chinosimudzirawo kushanda kweanonamira, zvichiita kuti zvive nyore kuisa uye kugadzirisa mataira.
mukupedzisa
Cellulose ethers yakaratidzwa kuvandudza zvakanyanya kushanda kwematairi adhesives. Sezvo kudiwa kwematairi ekushanda kwepamusoro-soro kunoramba kuchiwedzera, kuiswa kwe cellulose ethers mumatairi ekunamira maumbirwo kwakakosha. Kushandiswa kwema cellulose ethers mumatairi anonamira kunonatsiridza kuchengetedzwa kwemvura yekunamatira, kusimba kwechisungo, kuchinjika uye kushanda. Izvi zvivakwa zvinovimbisa kuti inonamira inogona kumira kushushikana uye deformation, ichipa yakavimbika fixation yematairi kune akasiyana substrates.
