Cellulose ether rudzi rwepolymer compound inowanikwa nekushandiswa kwemakemikari e cellulose yechisikigo, iyo ine kunyunguduka kwakanaka, kukora, kuchengetedza mvura uye hunhu hwekugadzira firimu. Mhando dzakajairika dze cellulose ether dzinosanganisirahydroxypropyl methylcellulose (HPMC), methylcellulose (MC), hydroxyethyl cellulose (HEC), hydroxyethyl methylcellulose (HEMC), nezvimwewo. Zvinoshandiswa zvakanyanya mukuvaka, kunyanya mumasisitimu edhaka rakaoma rakasanganiswa.
1. Maitiro ekuita kwe cellulose ether mudhaka
Mumaformula emazuva ano emortar, cellulose ether, sechinhu chakakosha chemakemikari, inonyanya kuita basa mune zvinotevera:
1.1. Kuchengetedzwa kwemvura kwakavandudzwa
Mamorekuru e-cellulose ether akapfuma mumapoka anonyungudutsa mvura, anogona kunyungudutsa nekukiya mvura isina kuyerera, kunonoka kubuda kwemvura uye kupinda kwemvura, kubvumira mvura kuti itore chikamu zvizere mukuita kwemvura inonyungudutsa simende, uye kuvandudza kushanda kwesimba rekutanga. Pakuvaka pamusoro pezvinhu zvine mvura inonyungudutsa yakasimba (senge kongiri ine mhepo, zvidhinha), cellulose ether inogona kudzivirira mvura yakawandisa uye kudzivirira kutsemuka nekuputika.
1.2. Kukora uye kuvandudza mashandiro ekuvaka
Cellulose ether inogona kuvandudza zvakanyanya kunaka kwesimbi uye thixotropy yesimbi, kuitira kuti simbi iratidze kuyerera kwakanaka uye mashandiro ekuvaka pakusanganisa nekushandisa, asi ine hukama hwakanyanya uye hunodzivirira kutsvedza mumamiriro asina kusimba, nokudaro ichivandudza kutsetseka kwesimbi uye kuderedza kudzika kwesimbi.
1.3. Kuvandudza simba rekubatana
Nekuwedzera kubatana kwemota uye kushanda kwekubatana kwemukati memota ne substrate, cellulose ether inovandudza simba rekubatana kwemota, ichidzivirira matambudziko akadai sekubvisa madziro uye kuvharika kwegomba muchikamu chekupedzisira, uye inonyanya kukodzera kune anonamira mataira, mamota anozvienzanisa uye masisitimu ekudzivirira ekunze.
1.4. Kunonotsa nguva yekugadzirisa uye kuvandudza mashandiro
Cellulose ether inogona kuwedzera nguva yekuvhurika kwemota, zvichibvumira vashandi kuti vave nenguva yakawanda yekugadzirisa nekugadzirisa panguva yekuvaka, uku vachidzivirira zvikanganiso zvekuvaka zvinokonzerwa nekuoma nguva isati yakwana.
2. Kushandiswa kwe cellulose ether mumhando dzakasiyana dzematura
2.1. Kupurasita dhaka
Kuwedzera cellulose ether mudhaka rekupurasita kunogona kunatsiridza kunamira pakati pedhaka nemadziro, uye kudzivirira matambudziko akadai se "kuvhunika nekutsemuka". Kuchengetedza kwayo mvura zvakanaka kunogonawo kuve nechokwadi chekuti dota rinooma zvakaenzana uye kunatsiridza kupedzisa.
2.2. Kunamira Mataira
Zvinonamira zvemataira zvine zvinodiwa zvakanyanya kuti zvirambe zvichichengetedza mvura uye zvisatsvedze. Cellulose ether inogona kuwedzera simba rayo rekubatanidza, kudzivirira mataira kuti asatsvedzerere pasi, uye kuve nechokwadi chekuti zvinonamira zvakanaka kumashure kwemataira zvine mvura shoma.
2.3. Dura rinozvienzanisa
Cellulose ether inoita kuti mvura igare yakafanana uye igare yakagadzikwa mumota inoyera yega kuitira kuti ive nechokwadi chekuti yakarongedzwa zvakaenzana pasina matambudziko emhando yepamusoro akadai sekubuda ropa uye kutsemuka. Mhando dze cellulose ether dzine viscosity yakaderera dzakakodzera kushandiswa kwakadaro.
2.4. Dura rekudzivirira kupisa (EIFS system)
Musystem yekudzivirira madziro ekunze, cellulose ether inowedzerwa kune bonding mortar uye anti-cracking mortar kuti ivandudze kuramba kutsemuka, kuwedzera simba re bonding, uye kuvandudza kugara kwenguva refu uye kugadzikana kwesystem yese.
2.5. Dhaka rekugadzira masonry rakasanganiswa nevhu rakaoma
Dhaka rekugadzira masonry rakasanganiswa nemvura rinowanzo shandiswa pakuvaka masonry ezvidhinha. Cellulose ether inogona kuvandudza kupomba kwayo, kuchengetedza mvura uye kudzivirira kudonha, kuita kuti dhaka rive rakafanana uye rakazara, uye kuwedzera huwandu uye simba rekumanikidza redhaka.
3. Zvinhu zvinokanganisa mashandiro
Kushanda kwe cellulose ether kune simba guru pakushanda kwekupedzisira kwedhaka, kunyanya kusanganisira zvinhu zvinotevera:
Chiyero chekusimba: High-viscosity cellulose ether yakakodzera mamortar anoda hunhu hwakanyanya hunodzivirira kutsvedza, nepo low viscosity yakakodzera zvigadzirwa zvinozvienzanisa.
Dhigirii rekutsiva (DS) uye molar substitution (MS): Aya ma parameter maviri anosarudza kunyungudika, kuchengetwa kwemvura uye kugadzikana kwe cellulose ether.
Saizi yezvikamu: Hupfu hwakatsetseka huri nyore kupararira mudura, zvichivandudza kufanana kwese.
Mwero wekunyungudika: Cellulose ether inonyungudika nekukurumidza inobatsira kuvandudza kushanda zvakanaka kwekugadzira uye kusanganisa kushanda zvakanaka.
4. Mazano ekushandisa uye matanho ekudzivirira
Sarudza viscosity yakakodzera uye rudzi rwe cellulose ether kuti ienderane nezvinodiwa zvemortar system.
Maitiro ekusanganisa anofanira kuve nechokwadi chekuti cellulose ether yakapararira zvakaenzana kudzivirira kusangana kwenzvimbo kuchikanganisa mashandiro.
Dzora huwandu hwekuwedzera, kazhinji 0.1%-0.5% yehuremu hwesimende. Yakawandisa inogona kukanganisa kusimba uye nguva yekuoma.
Kana ikashandiswa pamwe nezvimwe zvinowedzerwa (zvakaita sehupfu hwelatex hunonyungudika, chinodzikisa mvura, nezvimwewo), kutarisirwa kunofanira kupihwa pakuongorora kuenderana kwechinhu chacho.
Seimwe yezvinowedzerwa zvikuru mudhaka remazuva ano rakaoma rakasanganiswa,cellulose ether ine basa guru mukuvaka, hunhu hwemakanika uye kugara kwenguva refu. Nekuvandudzwa kwezvivakwa zvakasvibira uye zvivakwa zvakagadzirwa kare, kudiwa kwedhaka repamusoro-soro kuri kuramba kuchikura, uye mhando netekinoroji ye cellulose ether zviri kugara zvichigadziriswa. Kusarudzwa kwakanaka uye kushandiswa kwesainzi kwe cellulose ether kuchavandudza zvakanyanya mhando yezvigadzirwa zvedhaka uye kushanda zvakanaka kwekuvaka, inova nzira yakakosha yekuvandudzwa kwezvinhu zvekuvaka pari zvino.
