HPMC, inozivikanwawo se hydroxypropylmethylcellulose, ndeye multifunctional polymer iyo yakawana kugamuchirwa kwakafara muakasiyana maindasitiri ekushandisa. Ihupfu huchena husinganhuhwi, husingarapike, hunyungudika nyore mumvura uye nezvimwe zvinonyungudutsa. HPMC inogadzirwa nekemikari kushandura yakasikwa cellulose inotorwa kubva kumakwati emuti. Iyo inonyanya kushandiswa yeHPMC iri muindasitiri yekuvaka, iyo inoshandiswa sechinhu chikuru chesimende-based tile adhesives.
Cement-based tile adhesives inowanzoshandiswa pakuvaka zvivako zvekugara uye zvekutengesa. Ivo vanofarirwa pane echinyakare simende dhaka nekuda kwekusimba kwavo kwechisungo, kusimba kukuru uye nekukurumidza kuoma nguva. Kuwedzera HPMC kune simende-based tile adhesive inogona kuvandudza rheological zvimiro uye kuwedzera kushanda kwayo kwekubatana. Iyo zvakare inovandudza processability uye inobatsira kuderedza kuchengetwa kwemvura.
Basa reHPMC mune cementitious tile adhesives harigone kusimbiswa zvakanyanya. Iine zvakawanda zvakanakira, kusanganisira:
1. Kuvandudza kuchengetedza kwemvura: HPMC ine unhu hwakanaka hwekuchengetedza mvura, izvo zvinoreva kuti inogona kunyatsochengetedza huwandu hwemvura hunodiwa mukunamatira. Izvi zvinoita kuti adhesive iwedzere kushanduka uye inovandudza processability yayo.
2. Kuvandudza kukora: HPMC inoshanda sechinhu chakakora mune simende-based tile adhesives. Inosimudzira viscosity yekunamatira, ichibvumira kuti ishandiswe nyore nyore pamusoro penzvimbo huru pasina kudonha kana kumhanya.
3. Kuvandudza simba rekubatanidza: HPMC inovandudza simba rekubatanidza pakati pekunamatira uye substrate. Izvi zvinokonzerwa nekukwanisa kwayo kuderedza kuumbwa kwehomwe dzemhepo, izvo zvinoderedza chisungo.
4. Kuvandudza kuputika kupikisa: HPMC inopa kuwedzera elasticity kune adhesive. Izvi zvinobatsira kuderedza kuumbwa kwekuputika, izvo zvinogona kuderedza zvisungo uye kukanganisa simba rose rechimiro.
5. Kuvandudza kusimba: HPMC inobudirira inovandudza kusimba kwesamende-based tile adhesive. Imhaka yekuti inoshingirira kumvura, makemikari, uye tembiricha yakakwira, zvichiita kuti ive yakakodzera kushandiswa munzvimbo dzakaoma.
6. Kuvandudza kushanda kwekushanda: Kuwedzera HPMC kune simenti-based tile adhesive inogona kuvandudza zvakanyanya kushanda. Iyo inobvumira kunamira kupararira zvakanaka pamusoro pepamusoro kune yakanyanya kuenzana, inowirirana kupera.
7. Kuvandudzwa Kwekugadzirisa: HPMC inovandudza kuwirirana uye kunamatira, zvichiita kuti zvive zvakanaka kune zvakasiyana-siyana zvekushandisa.
Muchidimbu, HPMC chinhu chakakosha mukugadzira simende-based tile adhesives. Zvinhu zvayo zvakasiyana-siyana zvinonyanya kuvandudza kunaka kwekunamatira, zvichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekuvaka. Zvichienderana nekushandiswa, HPMC inowanikwa mumagiredhi akasiyana uye mafomati. Zvinokurudzirwa kuti usarudze mutengesi ane mukurumbira anogona kupa emhando yepamusoro HPMC zvigadzirwa zvinosangana nezvako chaizvo zvaunoda. Nechigadzirwa chakakodzera uye nzira yekushandisa chaiyo, unogona kunakidzwa nezvakawanda zvakanaka zveHPMC mumapurojekiti ako ekuvaka.
