Mataira anonamira anoita basa rakakosha mukuvaka kwemazuva ano, achipa kunamatira kwakasimba uye kuchinjika kune akasiyana matile application. Imwe yeakakosha ekuwedzera anoshandiswa mumatairi adhesive formulations ndeyeHydroxyethyl Methyl Cellulose (HEMC), cellulose ether inozivikanwa nekugona kwayo kukwidziridza mashandiro nekugadzirisa zvinonamira zverheological uye mechanical properties.
Zvimiro zveHydroxyethyl Methyl Cellulose (HEMC)
HEMC isiri-ionic, mvura-inonyungudika polima yakabva muselulosi. Inoshandiswa zvakanyanya mukuvaka zvinhu nekuda kwayokukora, kuchengetedza mvura, uye firimu-kugadzira zvinhu. Mumatairi anonamira, KimaCell®HEMC inoshanda searheology modifier, kuvandudza kushanda kwese kwekushandisa.
Zvinhu zvakakosha zveHEMC:
- Kuchengeta mvura:Inodzivirira kuoma nguva isati yakwana, kuve nechokwadi chekuti hydration yakakodzera ye simenti.
- Thickening agent:Inowedzera kuwirirana uye kushanda.
- Inovandudza adhesion:Inowedzera simba rekubatanidza pakati pemataira uye substrates.
- Inowedzera nguva yekuvhura:Inobvumira kushanda kwenguva refu kwekuisa matairi.

Mhedzisiro yeHEMC paTile Adhesive Performance
1. Kuvandudza Kuchengetedza Mvura
Kuchengetedzwa kwemvura chinhu chakakosha mukuita kwekunamira kwematairi, kunyanya mune simende-based adhesives. HEMC inonyanya kunatsiridza kuchengetwa kwemvura, kuderedza chiyero che evaporation uye kuve nechokwadi chakakwana sement hydration. Izvi zvinonyanya kubatsira mumamiriro ekupisa uye akaoma, kudzivirira kukanganisa kwekunamatira nekuda kwekuoma nguva isati yakwana.
2. Kuwedzeredzwa Kwekushanda uye Kuenderana
Kuwedzerwa kweHEMC kunonatsiridza rheological properties yeadhesives tile, zvichiita kuti zvive nyore kusanganisa, kupararira, uye kubata. Nekudzora viscosity, HEMC inodzivirira kudonha mumashandisirwo akatwasuka, ichibvumira matiles kuti arambe ari panzvimbo pasina kutsvedza. Izvi zvinonyanya kukosha kumapurojekiti ekuisa matairi emadziro.
3. Kuwedzera Adhesion Simba
HEMC inokwidziridza simba rekubatanidza pakati pemataira uye substrates nekusimudzira zvirinani hydration ye simenti zvinhu. Yakakodzera hydration inovimbisa kuvandudzwa kwematrix akasimba, zvichiita kuti pave nekuvandudzwa kwekunamatira kushanda. Izvi zvinoguma nekudzikiswa kwetairi uye kusimba kuri nani kweiyo tiling system.
4. Yakawedzerwa Nguva Yekuvhura
Kuvhura nguva inoreva nguva mukati meiyo matiles anogona kugadziridzwa mushure mekushandisa adhesive. KimaCell®HEMC inorebesa nguva yakazaruka nekunonotsa kubuda kwemvura. Izvi zvinopa kuchinjika panguva yekumisikidza, kuderedza mukana wekutangisa mataira nekuda kwekuiswa kusina kunaka.
5. Slump Resistance
Kune vertical tileng application, slump kuramba kwakakosha kudzivirira matiles kubva pakutsvedza asati agadzika. HEMC inowedzera viscosity yekunamatira, kuve nechokwadi chekuti mataira anoramba aripo mushure mekushandisa. Ichi chivakwa chinonyanya kubatsira muhombe-fomati mataira uye inorema matombo ekushandisa.
6. Kuvandudzwa kweFreeze-Thaw Kugadzikana
Mataira anonamira ane HEMC anoratidza kukwidziridzwa kuramba kutonhora-kunyungudika kutenderera. Iyo polymer inobatsira kuchengetedza kunamatira kutendeseka mukushanduka-shanduka tembiricha, kudzivirira kutsemuka uye kutadza nekuda kwekuwedzera kwekupisa uye kuderera.
HEMCchinhu chakakosha chekuwedzera mumatairi anonamira maumbirwo, inosimudzira mashandiro munzira dzakawanda. Kugona kwayochengetedza mvura, kuvandudza kushanda, kusimbisa kunamatira, uye kuwedzera nguva yakazarukainoita kuti ive yakakosha mumashandisirwo emazuva ano ekuisa matairi. Nekugadzirisa kuwanda kweKimaCell®HEMC mumatairi anonamira, vagadziri vanogona kuwana emhando yepamusoro zvigadzirwa zvinosimbisa kusimba, nyore kushandisa, uye inosimudzira kubatanidza kuita. Kufambira mberi mune ramangwana mune cellulose ether tekinoroji inogona kuwedzera kunatsiridza basa rayo mukunamira kwekuvaka, ichiita kuti matairi ashande uye akavimbika.
