Cellulose ether (CE) musanganiswa wepolymer musanganiswa unowanikwa nekugadziriswa kwemakemikari echisikigo cellulose. Inoshandiswa zvakanyanya mumatairi ekunamatira mune zvekuvaka. Yayo yakasarudzika kemikari chimiro uye zvemuviri zvimiro zvinopa iyo yakakosha mabhenefiti mukuvandudza mashandiro ematairi anonamira.
1. Kukora uye kuturika zvinhu
Cellulose ether inonyanya kuita seyakakora mumatairi anonamira. Inogona kuwedzera zvakanyanya viscosity uye kuenderana kweiyo sisitimu, nekudaro optimize kuvaka uye kushanda kwekuita kweadhesive. Nekuwedzera viscosity yeadhesive, cellulose ether inogona kunyatso kumisa zvimedu zvakasimba uye kudzivirira colloids kubva kune stratification uye kunaya kwemvura panguva yekuchengetedza kana kushandiswa.
Kukora mhedzisiro: Cellulose ether inogona kuumba network dhizaini mune aqueous solution, encapsulate uye kumisa simende zvimedu, uye kuita kuti sisitimu ive nepamusoro viscosity. Ichi chivakwa chinobatsira kudzivirira kutsvedza kwematairi anonamira panguva yekuvaka panzvimbo dzakamira.
Suspension stability: Nekuparadzira zvakaenzana zvimedu mune viscous matrix, cellulose ethers inobvumira mataira anonamira kuti arambe ari yunifomu panguva yekumira, nokudaro kuve nechokwadi chekushanda kwakanaka uye kwekupedzisira kusungirira simba.
2. Kuchengeta mvura
Kuchengeta mvura ndeimwe yemabasa akakosha e cellulose ethers. Inogona kutora mvura yakawanda mumatairi ekunamatira, zvichiita kuti mvura isunungurwe zvishoma nezvishoma. Iri basa rakakosha kune hydration reaction yesimende-yakavakirwa zvinhu uye inobata zvakananga maitiro ekurapa uye kusungirira zvivakwa zvematairi anonamira.
Hydration reaction support: Kuchengetwa kwemvura kwe cellulose ethers kunovimbisa kuti simende ine mvura yakakwana ye hydration panguva yekuomeswa kwemaitiro, izvo zvakakosha pakuvandudza simba uye kusungirira zvinhu zvekunamatira.
Yakawedzerwa nguva yakazaruka: Nekuti kuchengetwa kwemvura kunowedzera nguva iripo yekunyorova pamusoro pekunamatira, vashandi vekuvaka vane nguva yakawanda yekugadzirisa uye kumira, nekudaro vachivandudza kugona kwekuvaka.
3. Kuvandudza rheological properties
Cellulose ethers ine simba guru pane rheological properties ye tile adhesives. Rheology inoreva kuyerera uye deformation maitiro echinhu chiri mukushushikana. Cellulose ethers inogona kugadzirisa kushushikana kwegoho uye thixotropy yekunamatira, nekudaro ichivandudza kushanda kwayo.
Kudzora kushushikana kwegoho: Cellulose ethers inogona kuumba imwe simba rezvimiro mukunamira, saka imwe simba rekunze rinodiwa kutanga colloid kuyerera. Izvi zvinobatsira kudzivirira kunamira kubva pakudonha kana kutsvedza panguva yekuvaka.
Thixotropy kunatsiridza: Cellulose ethers inoita kuti tile yekunamatira iratidze viscosity yakakwirira kana yakamira, asi viscosity inoderera nokukurumidza pasi pechiito cheshear force, zvichiita kuti zvive nyore kupararira uye kupararira panguva yekuvaka. Mushure mokunge kuvakwa kwapera, viscosity inodzorerwa, iyo inobatsira kuchengetedza matairi panzvimbo.
4. Kuvandudza anti-sag performance
Kana uchiisa matiles panzvimbo dzakamira kana dzakarerekera, kudzivirira kunamira kubva pakutsvedza inyaya yakakosha. Cellulose ethers zvinobudirira kuvandudza maitiro e-anti-sag ekunamatira kuburikidza nekukora uye rheology kugadzirisa mabasa, zvichiita kuti colloid igadzirise zvakasimba matiles panguva yekuvaka yakatwasuka.
Sag control: Cellulose ethers inogona kuumba gel chimiro nehupamhi hwekubatana, izvo zvinoita kuti kunamira kuve nekunetseka kwegoho repamusoro pane yakatwasuka, nekudaro kudzivirira mataira kubva pakutsvedza.
5. Kuwedzerwa simba rezvisungo
Cellulose ethers inoita basa rakakosha mukuvandudza kusimba kwechisungo chezvinonamira. Kuchengetedza kwayo mvura uye rheological regulation zvivakwa zvinoita kuti mataira anonamira kuti apinde zviri nani pamusoro pemataira uye substrates, nekudaro achivandudza kunamatira.
Kunyorova kuita: Cellulose ether inogadzirisa kuyerera kwezvinonamira kuti zvikwanise kupinda zviri nani uye kunamatira kumusoro kwematiles uye substrates, kuwedzera nzvimbo yekubatanidza, uye kuvandudza kusimba kwekubatana.
Yakavandudzwa kufanana: Nekuda kwekukora mhedzisiro ye cellulose ethers, izvo zvinonamira zvinogovaniswa zvakaenzana, zvichideredza dambudziko rekusaenzana kwesimba rekubatanidza rinokonzereswa nekudonha kwezvinhu zvemuno.
6. Kudzivirira kutsemuka
Tile adhesives anowanzoita shrinkage uye kuputika nekuda kwekurasikirwa kwemvura panguva yekuomeswa nekuoma. Kuchengetedzwa kwemvura kwe cellulose ethers kunogona kudzikamisa kurasikirwa kwemvura, kuderedza kuomeswa kwemvura, uye kudzivirira kuputika.
Kuomesa shrinkage control: Nekudzora chiyero chekuburitswa kwemvura, cellulose ethers inogona kuderedza kuderera kweanonamatira panguva yekuomeswa, nekudaro kuderedza njodzi yekutsemuka.
7. Kuvandudzwa kwemamiriro ekunze uye kusimba
Cellulose ethers inogona zvakare kuvandudza kupikisa kwemamiriro ekunze uye kusimba kwematairi anonamira. Kugadzikana kwayo kwepamusoro mumamiriro ekunyorova kunogona kukwidziridza mashandiro ezvinonamira munzvimbo dzine hunyoro uye kuvandudza masimba ekurwisa kuchembera.
Kupokana kwehunyoro: Cellulose ethers inogona kuramba ichichengetedza mabasa avo munzvimbo dzine hunyoro, iyo inobatsira mataira anonamira kuti arambe akanamatira kwenguva refu pasi pemamiriro ehunyoro.
Anti-kuchembera: Cellulose ethers inovandudza kusimba kwenguva refu kwezvinonamira nekuchengetedza simentitious substrates kubva pakurasikirwa nekunyorova nekukurumidza uye kukukurwa kwezvakatipoteredza.
8. Kuchengeteka kwezvakatipoteredza
Cellulose ethers inotorwa kubva kune yakasikwa cellulose uye inogadzirwa kuburikidza nekugadziriswa kwemakemikari. Vane biodegradability yakanaka uye kushamwaridzana kwezvakatipoteredza. Mumamiriro ezvinhu ezvigadzirwa zvemazuva ano zvekuvaka izvo zvinowedzera kutarisa nezvekuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba, cellulose ethers ine mabhenefiti akakosha seyakachengeteka uye inoshanda yekuwedzera.
Kushandiswa kwe cellulose ethers mumatairi anonamira ndiyo kiyi yekuvandudza mashandiro avo. Iko kukora kwayo, kuchengetwa kwemvura, rheology kugadziridzwa, anti-sagging, yakawedzera bonding, uye kuputika kwekudzivirira zvivakwa zvinovandudza mashandiro ekuvaka uye yekupedzisira mhedzisiro yekunamatira mataira. Panguva imwecheteyo, iyo ecological chengetedzo ye cellulose ether inosanganawo nekuchengetedzwa kwezvakatipoteredza zvinodiwa zvemazuva ano zvekuvaka. Sekuwedzera kwakakosha kunoshanda, cellulose ethers icharamba ichiita basa rakakosha mumunda wekuvaka adhesives, zvichibatsira kukudziridzwa kweanoshanda uye anogara matile paving masisitimu.
