Hydroxypropyl Methyl Cellulose (HPMC)
1. Yakagadzikana kune asidi uye alkali, uye mhinduro yayo yemvura yakanyatsogadzikana muhuwandu hwepH = 2-12. Caustic soda uye mvura yeraimu haina mhedzisiro yakawanda pakuita kwayo, asi alkali inogona kukurumidza kuparara kwayo uye kuwedzera zvishoma viscosity yayo.
2. HPMC inzvimbo yakakwirira-yekuchengetedza mvura yemvura yakaoma yeupfu dhaka system, iyo inogona kuderedza kubuda kweropa uye dhigirii rekuisa dhaka, kuvandudza kubatanidzwa kwedhaka, kunyatsodzivisa kuumbwa kwepurasitiki mumatope, uye kuderedza mapurasitiki. cracking index of mortar.
3. Iyo isiri-ionic uye isiri-polymeric electrolyte, iyo yakanyatsogadzikana mune aqueous solutions ine metal salt uye organic electrolytes, uye inogona kuwedzerwa kune zvigadzirwa zvekuvaka kwenguva yakareba kuti ione kuti kusimba kwayo kunovandudzwa.
4. Kushanda kwekushanda kwedhaka kwakagadziridzwa zvakanyanya. Iyo dhaka inoita se "mafuta", iyo inogona kuita kuti majoini emadziro azere, anotsvedzerera pamusoro, kuita dhaka uye chigadziko chisungo chisungo zvakasimba, uye kuwedzera nguva yekushanda.
kuchengetedza mvura
Kuwana kuchengetedza kwemukati, izvo zvinobatsira pakuvandudzwa kwesimba renguva refu
Kudzivisa kubuda ropa, kudzivirira dhaka kubva pakugadzirisa uye kupera
Kuvandudza kutsemuka kwedhaka.
thicken
Anti-segregation, kuvandudza dhaka kufanana
Inovandudza wet bond simba uye inovandudza sag resistance.
kubuda ropa
Kuvandudza kuita kwedhaka
Sezvo viscosity ye cellulose ichikwira uye cheni ye molecular ichirebesa, mhepo-intraining mhedzisiro inova pachena.
Retarding
Synergizes nekuchengetedza mvura kuwedzera nguva yakavhurika yedhaka.
Hydroxypropyl starch ether (HPS)
1. Iyo yakakwira hydroxypropyl yemukati mu starch ether inopa sisitimu ine yakagadzikana hydrophilicity, ichiita yemahara mvura mumvura yakasungwa uye kuita basa rakanaka mukuchengetedza mvura.
2. Starch ether ine zvakasiyana hydroxypropyl content inosiyana mukukwanisa kwavo kubatsira cellulose mukuchengetedza mvura pasi pedosi imwechete.
3. Kutsiviwa kweboka rehydroxypropyl kunowedzera dhigirii rekuwedzera mumvura uye kumanikidzira nzvimbo yekuyerera yezvikamu, nokudaro kuwedzera viscosity uye thickening effect.
Thixotropic lubricity
Kukurumidza kupararira kwe starch ether mumatope emarara kunoshandura rheology yedhaka uye inoisa iyo thixotropy. Kana simba rekunze rikaiswa, viscosity yedhaka inodzikira, ichiva nechokwadi chekushanda kwakanaka, kupomba, uye endowment Kana simba rekunze rabviswa, viscosity inowedzera, kuitira kuti dhaka rive rakanaka rinopesana nekusagika uye anti-sag performance, uye mune putty powder, ine zvakanakira kuvandudza kupenya kweiyo putty mafuta, kupenya kupenya, nezvimwe.
Mhedzisiro yekubatsira kwekuchengetedza mvura
Nekuda kwekuita kweboka re hydroxypropyl muhurongwa, starch ether pachayo ine hydrophilic maitiro. Kana yakasanganiswa ne cellulose kana kuwedzerwa kune imwe dhaka, inogona kuwedzera kuchengetwa kwemvura kune imwe nhanho uye kugadzirisa pamusoro pekuomesa nguva.
Anti-sag uye anti-slip
Yakanakisa anti-sagging mhedzisiro, kuumba maitiro
Redispersible latex poda
1. Kuvandudza kushanda kwedhaka
Iyo rubber powder particles inoparadzirwa muhurongwa, ichipa sisitimu ine mvura yakanaka, inovandudza kushanda uye kushanda kwedhaka.
2. Kuvandudza chisungo chesimba uye kubatana kwedhaka
Mushure mekunge hupfu hwerabha hwaparadzirwa mufirimu, inorganic matter uye organic matter mumortar system zvinosanganiswa pamwechete. Zvinogona kufungidzirwa kuti jecha resimende muvhu ndiro skeleton, uye latex powder inoumba ligament mairi, iyo inowedzera kubatana uye simba. gadzira chimiro chinochinjika.
3. Kuvandudza kudzivirira kwemamiriro ekunze uye kutonhora-kunyunguduka kwedhaka
Latex powder is thermoplastic resin ine yakanaka kuchinjika, iyo inogona kuita kuti dhaka ribate nekutonhora kwekunze uye shanduko yekushisa, uye zvinodzivirira kudzivirira dhaka kubva pakutsemuka nekuda kwekushanduka kwekushisa.
4. Kuvandudza flexural simba redhaka
Zvakanakira zvepolymer uye simende paste zvinopindirana. Kana makatsemuka achigadzirwa nekunze kwesimba, iyo polymer inogona kuyambuka kuputika uye kuvharidzira kuputika kubva pakuwedzera, kuitira kuti kuomarara kwekupwanyika uye deformability yedhaka ivandudzwe.
