Munzvimbo yezvivakwa zvekuvaka, mabhandi anoita basa rakakosha pakuona kutendeseka nekusimba kwezvivakwa zvakasiyana. Kana zvasvika pakuisa matairi maapplication, mabhainda akakosha kuchengetedza mataira kune pamusoro zvinobudirira. Imwe bhainda yakadaro iyo yakawana kutariswa kwakakosha kune ayo akasiyana zvivakwa uye eco-hushamwari hunhu iHydroxyethyl Methyl Cellulose (HEMC).
1. Kunzwisisa HEMC:
Hydroxyethyl Methyl Cellulose (HEMC) isiri-ionic cellulose ether inotorwa kubva kune yakasikwa cellulose kuburikidza neakatevedzana emakemikari ekugadzirisa. Ihwo hupfu hwakachena kusvika kuchena, husinganhuhwi, uye husingaravi hunyoro hunonyungudika mumvura uye hunoita mugadziriso wakajeka, une viscous. HEMC inogadzirwa nekurapa cellulose nealkali uye yozoigadzirisa ne ethylene oxide uye methyl chloride. Chigadzirwa chinoguma chinoratidza musanganiswa wezvivakwa zvinoita kuti ive yakakodzera kune akasiyana maapplication, kusanganisira senge bhinda rematairi.
2. Zvinhu zveHEMC Zvinoenderana neTile Binding:
Kuchengetedzwa Kwemvura: HEMC ine yakanakisa yekuchengetedza mvura zvivakwa, izvo zvakakosha kune mataira adhesives. Inobatsira kuchengetedza hunyoro hunodiwa mumusanganiswa wekunamatira, zvichibvumira hydration yakakodzera yezvinhu zvesimenti uye kuve nechokwadi chekunamatira kune zvose tile uye substrate.
Kukora Mhedzisiro: HEMC inoshanda seyakakora mumiriri kana yawedzerwa kune mvura-based formulations. Inopa viscosity kumusanganiswa wekunamatira, kudzivirira kudonha kana kudonha kwematiles panguva yekushandisa. Uku kukora mhedzisiro zvakare kunofambisa zvirinani kushanda uye nyore kushandisa.
Firimu Kuumbwa: Pakuoma, HEMC inoumba firimu inoshanduka uye yakabatana pamusoro pepamusoro, iyo inowedzera kusimba kwechisungo pakati pe tile uye substrate. Iyi firimu inoshanda sechidziviriro chekudzivirira, kuvandudza kupikisa kwetairi yekunamatira kune zvakatipoteredza zvinhu zvakadai sehunyoro uye kushanduka kwekushisa.
Kuvandudzwa Kwekushanda Kwekushanda: Kuwedzerwa kweHEMC kune matile adhesive formulations inovandudza kushanda kwavo nekuderedza kunamatira uye kuwedzera kupararira. Izvi zvinobvumira kushandiswa kwakapfava uye kwakafanana kweadhesive, zvichikonzera kufukidzwa kuri nani uye kunamatira kwematiles.
3. Zvishandiso zveHEMC muTile Binding:
HEMC inowana kushandiswa kwakakura mune dzakasiyana siyana dzinosunga mataira maapplication, kusanganisira:
Tile Adhesives: HEMC inowanzoshandiswa sechinhu chakakosha mumatairi anonamatira nekuda kwekugona kwayo kuvandudza kunamatira, kushanda, uye kuchengetedza mvura. Iyo inonyanya kukodzera kune yakaonda-yebhedha yekumisikidza mataira apo inotsvedzerera uye yakafanana adhesive layer inodiwa.
Grouts: HEMC inogonawo kuiswa mumatairi grout magadzirirwo kuti awedzere kuita kwavo. Iyo inovandudza kuyerera kweiyo grout musanganiswa, ichibvumira kuzadza nyore kwemajoini uye zvirinani compaction kutenderedza mataira. Uyezve, HEMC inobatsira kudzivirira shrinkage uye kuputika mugrout sezvainorapa.
Self-Leveling Compounds: Mukuzvimisikidza pasi makomisheni anoshandiswa kugadzirira subfloors isati yaiswa mataira, HEMC inoshanda senge rheology modifier, ichiona kuyerera kwakaringana uye kuenzana kwechinhu. Inobatsira kuwana yakatsetseka uye kunyange pamusoro, yakagadzirira kushandiswa kwematiles.
4. Zvakanakira Kushandisa HEMC seTile Binder:
Yakavandudzwa Adhesion: HEMC inokwidziridza chisungo chesimba pakati pematairi uye substrates, zvichikonzera kugadzika uye kwenguva refu yekuisa mataira.
Kuwedzerwa Kushanda Kwekushanda: Kuwedzerwa kweHEMC kunovandudza kushanda uye kupararira kwematairi adhesives uye grouts, zvichiita kuti zvive nyore kushandisa uye kuderedza nguva yekuisa.
Kuchengetedzwa Kwemvura: HEMC inobatsira kuchengetedza huwandu hwakakwana hwehunyoro mumatairi anonamira maumbirwo, kusimudzira kwakaringana hydration yesimende zvinhu uye kuderedza njodzi yekutadza kunamatira.
Yakaderedzwa Shrinkage uye Kutsemuka: Iyo firimu-inogadzira zvimiro zveHEMC inobatsira kuderedzwa shrinkage uye kuputika mumatairi anonamira uye grouts, kuve nechokwadi chisungo chakagadzikana uye chakavimbika nekufamba kwenguva.
Inoenderana Nezvakatipoteredza: Seselulosi-yakavakirwa polymer inotorwa kubva kune zvinogonekazve zviwanikwa, HEMC ine hushamwari kwezvakatipoteredza uye inogadzikana, zvichiita kuti ive sarudzo inokwezva yemapurojekiti ekuvaka egirini.
5. Mhedziso:
Hydroxyethyl Methyl Cellulose (HEMC) inopa huwandu hwakawanda hwezvivakwa zvinoita kuti ive yakakodzera binder yekumisikidza mataira. Kuchengeta kwayo mvura, kukora, kugadzira firimu, uye kushanda-kunatsiridza zvivakwa zvinobatsira mukuvandudza kunamatira, kusimba, uye nyore kushandisa mune akasiyana matile anosunga maapplication. Nechimiro chayo-eco-hushamwari uye nekuita kwakaratidza, HEMC inoramba iri sarudzo inosarudzika kune makondirakiti uye vavaki vari kutsvaga mhinduro dzakavimbika uye dzakasimba dzemapurojekiti ekuisa matairi.
