Doka chinhu chekuvakisa chinoshandiswa kusunga nekuzadza maburi pakati pezvidhinha, mabhuroko ekongiri, uye zvimwe zvakafanana zvekuvaka.Kazhinji inoumbwa nemusanganiswa we simenti, jecha nemvura.Nekudaro, madhaka anogona zvakare kugadziridzwa nekuwedzera cellulose ethers, iyo inosimudzira kuenderana kwezvinhu uye anti-sag zvivakwa.
Cellulose ethers mapolymers anonyungudika nemvura anobva muselulosi, makhahydrates echisikigo anowanikwa mumiti.Iwo anowanzo shandiswa mukuvaka zvinhu se thickeners, stabilizers uye mvura inochengetedza vamiririri.Cellulose ethers yakawanikwa ichishanda mukuvandudza zvinhu zvedhaka, kusanganisira kushanda, simba uye kusimba.
Muchikamu chino tichakurukura kushandiswa kwe cellulose ethers mumatope uye maitiro avo pakuenderana uye sag kuramba.
Kusagadzikana kwedhaka
Kubatana kwedhaka zvinoreva kugona kuumba, kuumba nekupararira pasina kutsemuka kana kugwedeka.Icho hunhu hwakakosha hunosarudza kusununguka kwekushandisa uye kunaka kwechigadzirwa chakapedzwa.Dhaka rinoenderana richabatana zvakasimba uye zvakaenzana kune zvigadzirwa zvekuvaka, zvichigadzira chimiro chakasimba uye chakasimba.
Nekudaro, kuwana kuenderana chaiko kwedhaka kunogona kuve kwakaoma, kunyanya kana zvinhu zvekuvakisa zviine nzvimbo isina kuenzana kana chimiro.Uku ndiko kubatsirwa kwekushandisa cellulose ethers.
Cellulose ethers inogona kuvandudza kuenderana kwedhaka nekuwedzera iyo inobatisa mvura yechinhu.Kana cellulose ethers yawedzerwa kumusanganiswa wedhaka, inotora unyoro uye inoita gel-sechinhu chinosunga zvimwe zvinhu pamwechete.Iyi gel-yakaita sechinhu chinobatsirawo kuderedza shrinkage yedhaka, nokudaro kuderedza kuputika uye mapeji muchigadzirwa chakapedzwa.
Anti-sag zvimiro zvedhaka
Sag resistance yedhaka inoreva kugona kwayo kuchengetedza chimiro chayo uye kudzivirira kudonha kana yaiswa yakatwasuka.Zvimwe zvekuvaka, zvakaita semabhuroko ekongiri, zvine nzvimbo dzakakasharara dzinoda dhaka dzakakora kuti pave nechisungo chakasimba.Kana iyo dhaka yakashandiswa ikashaya sag resistance, inotsvedza kubva pamusoro, ichigadzira mapundu uye ichideredza simba rezvisungo.
Cellulose ethers inogona kuvandudza sag kuramba kwedhaka nekuwedzera viscosity yayo kana ukobvu.Iyi viscosity inobatsira dhaka kuchengetedza chimiro chayo kana ichiiswa panzvimbo yakatwasuka, ichidzivirira kubva pakutsvedza kana kudonha.Pamusoro pezvo, cellulose ethers inoshanda semafuta, zvichiita kuti dhaka rive nyore kupararira, kunyangwe panzvimbo yakaoma.
mukupedzisa
Kushandiswa kwe cellulose ethers mudhaka kwakawanikwa kuvandudza kuenderana kwezvinhu uye kuramba kusag.Cellulose ethers inowedzera simba rekuchengetedza mvura yedhaka, zvichiita kuti zvinhu zvienderane zvinobatanidza zvakaenzana kune zvigadzirwa zvekuvaka.Pamusoro pezvo, cellulose ethers inogona kuvandudza sag resistance yedhaka nekuwedzera viscosity yayo, ichiibvumira kuchengetedza chimiro chayo kana ichinge yaiswa panzvimbo yakatwasuka.
Pakazara, kubatanidzwa kwe cellulose ethers mumatope inhanho yakanaka munharaunda yekuvaka, inobvumira kubatanidza zviri nani, kugadzikana kukuru uye kuvaka kwepamusoro.
