Mashandisirwo Akanakisisa eHydroxypropyl Methylcellulose muZvivako
Hydroxypropyl Methylcellulose (HPMC) ndeimwe ye cellulose ethers dzinoshandiswa zvakanyanya mukuvaka kwemazuva ano. Nekuda kwekuchengetedza kwayo mvura, kukora, kugadzira mafirimu, uye hunhu hwekutonga rheology, HPMC inoita basa rakakosha mukuvandudza mashandiro ekugadzira simende negypsum. Kunzwisisa zviri pamusoro Kushandiswa kwehydroxypropyl methylcellulose muzvinhu zvekuvaka inobatsira vanogadzira, vagadziri, uye makondirakiti kugadzirisa mhando yechigadzirwa uye kushanda zvakanaka panzvimbo yacho.
Gwaro iri rehunyanzvi rinotsanangura kuti HPMC inoshandiswa kupi mukuvaka, mabasa ainoita, uye kuti inovandudza sei mashandiro ekupedzisira ekuvaka.
Chii chinonzi Hydroxypropyl Methylcellulose mukuvaka?
Hydroxypropyl methylcellulose i non-ionic cellulose ether inobva mu cellulose yechisikigo uye yakagadziriswa nemakemikari kuti inyungudike mumvura. Mumasystem ekuvaka, HPMC inonyanya kushanda se:
- Chinhu chinochengetedza mvura
- Mugadzirisi we thickener uye rheology
- Chinhu chinowedzera kushanda
- Mushonga wekudzivirira kenza
- Chinowedzerwa nguva yekuvhura
- Chinhu chinovandudza kugadzikana
Nekuti inoshanda zvinobudirira pahuwandu hwakaderera hwemushonga, HPMC inoonekwa sechinhu chinoshanda zvakanyanya muzvinhu zvekuvaka zvakasanganiswa nemafuta akaoma.
Mabasa Makuru eHPMC muSimende neGypsum Systems
| Basa | Kubatsirwa Kwekuita |
|---|---|
| Kuchengetwa kwemvura | Inodzivirira kurasikirwa nemvura nekukurumidza uye inovandudza kunyoroveswa kwemvura nesimende |
| Kukora | Inovandudza kuenderana uye kutonga kwekushandisa |
| Kudzora rheology | Zvinowedzera kupararira uye zvinoderedza kupatsanurwa |
| Kuwedzerwa kwenguva yekuvhura | Inobvumira nguva yakareba inoshanda panguva yekuisa |
| Rutsigiro rwekunamatira | Inovandudza kubatana ne substrates |
Mashandisirwo Akanakisisa eHydroxypropyl Methylcellulose muZvivako
1. Zvinonamira Mataira
Imwe yenzira dzakakosha dzekushandisa hydroxypropyl methylcellulose ndeye mafomura ekunamira matairaHPMC inobatsira kudzora kusviba uye kuchengetwa kwemvura, ichiva nechokwadi chekuti simende inonyorovesa mvura zvakanaka uye mataira akabatana zvakasimba.
- Inovandudza kuramba kutsvedza
- Inowedzera nguva yekuvhura
- Inowedzera kupararira
- Inoderedza kudonha kwemataira panzvimbo dzakamira
- Inovandudza simba rekupedzisira rekubatana
Chiyero chemushonga wakajairika: 0.2%–0.5% yehuremu hwemusanganiswa wakaoma.
2. Dry Mix Mortar
Mumasystem emota yakasanganiswa yakaoma, HPMC inoshandiswa kudzikamisa musanganiswa uye kuvandudza mashandiro ekuvaka. Inoita kuti mvura ipararire zvakaenzana uye inoderedza kubuda kweropa nekupatsanurwa.
- Kushanda zvakanaka kwetroweling
- Njodzi yekutsemuka yakaderedzwa
- Kubatana kwakavandudzwa
- Kurapa kwakafanana
3. Putty yemadziro nejasi rakapfava
Zvigadzirwa zveputty pamadziro neskim coat zvinoshandisa HPMC kuti zvishande zvakanaka uye kuti pamusoro pazvo pave nerunako. Kusarudza viscosity zvakanaka kunobatsira kuti pave nekushanda zvakanaka uye kuti pasave nekudzikama.
- Kushanda kwekucheka kwakapfava
- Kuenzanisa kwepamusoro kwakavandudzwa
- Kuderedzwa kwehupfu
- Kuchengetwa kwemvura kuri nani panguva yekurapwa
4. Kupurasita nesimende uye Kugadzira
Mukushandisa plaster ne rendering, hydroxypropyl methylcellulose inovandudza body yemortar uye inoderedza kurasikirwa kwe rebound panguva yekupfapfaidza kana kushandisa nemaoko.
- Kunamira zviri nani pamadziro nepadenga
- Kuderedzwa kwemarara ezvinhu
- Kukwanisa kupomba mvura zviri nani
- Kudzivirira kutsemuka kwakanyanya
5. Makomponi Anozvienzanisa
Kunyangwe ichishandiswa pamazinga akaderera, HPMC inobatsira pakuenzana kwe viscosity mumasisitimu ekuzvienzanisa, zvichibatsira kudzora kuyerera kwemvura pasina kupatsanurwa zvakanyanya.
- Kudzora kuyerera
- Kumiswa kwezvikamu
- Kuderedza zvikanganiso pamusoro
6. Zvigadzirwa Zvinogadzirwa neGypsum
Mapurasita egypsum nemajoini anoshandisa HPMC kudzora kudiwa kwemvura uye kuvandudza mashandiro ekubata.
- Nguva yekushanda yakawedzerwa
- Kupararira kwakavandudzika
- Kuderedza zvikanganiso zvekudzikira
- Kupedzisa kwepamusoro kuri nani
Kusarudzwa kweHPMC Viscosity yekushandiswa kwekuvaka
Zvinhu zvakasiyana zvekuvaka zvinoda magiredhi akasiyana eHPMC viscosity:
| Kushandiswa | Mhando yeViscosity Yakajairika |
|---|---|
| Namira yemataira | 40,000 – 100,000 mPa·s |
| Putty yemadziro | 50,000 – 150,000 mPa·s |
| Purasi | 20,000 – 60,000 mPa·s |
| Kuzvienzanisa | Kusviba kwakaderera kusvika pakati nepakati |
Mazano Ekugadzira Maitiro Akanaka
- Wedzera HPMC panguva yekusanganisa yakaoma kuti uparadzire zvakanaka
- Dzivisa kuisa zvakananga mumvura inopisa
- Batanidza giredhi re viscosity nenzira yekushandisa
- Edza kuchengetedza mvura uye nguva yekushanya pamwe chete
- Gadzirisa chiyero chemvura zvichienderana nejecha uye rudzi rwesimende
Mibvunzo Inowanzo bvunzwa nezveSEO: Mashandisirwo eHydroxypropyl Methylcellulose mukuvaka
Sei HPMC ichikosha mukunamira mataira?
HPMC inoita kuti mvura irambe ichichengetwa, ishande kwenguva yakareba, uye inoita kuti mataira asadonhe zvakanaka, izvo zvakakosha kuti mataira akwanise kusungirirwa zvakanaka uye kuti agare akavimbika pakuiswa.
HPMC inogona kuvandudza kushanda zvakanaka kwedhaka here?
Ehe. HPMC inogadzirisa rheology uye inovandudza kupararira, zvichiita kuti dhaka rive nyore kuisa uye kugadzira chimiro.
Ko HPMC inoshandiswa here muzvigadzirwa zvegypsum?
Ehe. Inoshandiswa zvakanyanya mumaplaster egypsum uye majoint compounds kuwedzera nguva yekushanda uye kuvandudza kunaka kwekupedzisa.
Mhedziso
Iyo inonyanya kushandiswa muzvinhu zvekuvaka ndeyekuvandudza mashandiro, kudzora mashandiro, uye kuwedzera kugara kwenguva refu. Kubva kuma tile glues nema dry mix mortars kusvika kuma wall putty nema gypsum systems, HPMC yave chinhu chakakosha mukugadzirwa kwezvivakwa zvemazuva ano. Kusarudzwa kwemagiredhi akakodzera uye kugadzirisa dosage ndizvo zvakakosha kuti pave nemhedzisiro yekuvaka inogara iripo uye yemhando yepamusoro.
