Mashandisirwo eHydroxypropyl Methylcellulose muWall Putty neSkim Coat
Hydroxypropyl Methylcellulose (HPMC) ndeimwe yezvinowedzerwa zvakakosha zvinoshandiswa mukugadzira wall putty uye skim coat. Seye cellulose ether inoshanda zvakanyanya, inoita kuti mvura irambe ichichengetwa, iwedzere kukora, ivandudze mashandiro, uye inodzora kupedzisa kwenzvimbo. Kunzwisisa kiyi Mashandisirwo ehydroxypropyl methylcellulose mu wall putty uye skimcoat inobatsira vagadziri nevagadziri vemagadzirirwo kugadzira zvinhu zvekupedzisa zvakapfava, zvakagadzikana, uye zviri nyore kushandisa.
Gwaro iri rinotsanangura mashandiro anoita HPMC mumasisitimu eputty, mabhenefiti ainoita, masarudzo akakodzera e viscosity grade, uye mashandisirwo ekuwedzera dosage kuti uwane mhedzisiro yakafanana.
Chii chinonzi Wall Putty uye Skim Coat Materials?
Putty yemadziro neskim coat zvinhu zvitete zvinoiswa pamusoro peplaster kana concrete kuti pave nesubstrate yakatsetseka, yakagadzirirwa kupendwa. Zvinhu izvi zvinowanzo shandiswa pa:
- Zvisungo zvesimende kana gypsum
- Zvinhu zvinozadza zvakanaka (calcium carbonate, talc, nezvimwewo)
- Zvigadziriso zvePolymer
- Zvimwe zvinoshandiswa zvinoshanda zvakaita seHPMC
Nekuti zvidimbu izvi zvakatetepa uye zvakafumurwa, kudzora hunyoro uye maitiro ekushandisa zvakakosha - ndipo panotora basa guru rehydroxypropyl methylcellulose.
Mashandiro anoita HPMC muPutty neSkim Coat Systems
Kana ikasanganiswa nemvura, HPMC inonyorovesa uye inoumba mushonga wakasimba, wakakora unochinja rheology yemusanganiswa weputty. Izvi zvinogadzira chimiro cheputty chinodzorwa chinovandudza kubata uye kupora.
Mabasa makuru ekushanda anosanganisira:
- Chinhu chinochengetedza mvura
- Mutongi we rheology uye thickener
- Chinhu chinowedzera kushanda
- Mushonga wekudzivirira kenza
- Chinhu chinovandudza kupedzisa kwepamusoro
- Rutsigiro rwekuderedza kutsemuka
Mashandisirwo Akakosha eHydroxypropyl Methylcellulose muWall Putty
1. Kuchengetwa Kwemvura Kwakasimba
Putty yemadziro inoiswa muzvikamu zvitete, zvichiita kuti irasikirwe nemvura nekukurumidza. HPMC inovandudza zvakanyanya kuchengetedza mvura uye inoita kuti binder iwane mvura yakakwana.
- Inodzivirira kuoma nguva isati yakwana
- Inovandudza kubatana ne substrate
- Inoderedza kupurwa kwevhu pamusoro
- Inotsigira kukura kwesimba
2. Kuvandudzwa kweKukwesha neKukwesha Matayi
Kunzwa kwekushandisa chiratidzo chikuru chemhando yezvigadzirwa zveputty. Chimwe chezvinoshandiswa zvakanyanya nehydroxypropyl methylcellulose ndechekuvandudza kutsvedza uye kunzwa kwebanga.
- Kufamba kwebanga kwakapfava
- Kudhonzwa kwakaderedzwa
- Ukobvu hwakafanana hwerukoko
- Kudzora mucheto kuri nani
3. Kuramba Kudonha Kwemvura Panzvimbo Dzakamira
Putty ne skim coat zvinowanzoiswa pamadziro akamira uye padenga. HPMC viscosity chaiyo inobatsira kuchengetedza paste muviri uye inoderedza kutsvedza.
- Kubata kwakamira kuri nani
- Mitsetse yekupedzisa yakachena
- Kugadziriswazve kwakaderedzwa
4. Kuvandudza Kupedzisa Kwepamusoro
HPMC inobatsira kudzora magadzirirwo epaste uye kumiswa kwetii, zvichibatsira kuti nzvimbo dzekupedzisira dzive dzakapfava.
- Kuvandudzwa kwemazinga
- Maburi madiki akaderedzwa
- Kugamuchirwa kwependi kuri nani
- Chitarisiko chakafanana
Kuvandudzwa Kwekushanda Kwemajasi Akakora Kubva kuHPMC
Mumaforoma eskim coat, hydroxypropyl methylcellulose inovandudza mashandiro ekushandisa uye ekuporesa.
| Nzvimbo Yekushanda | Mhedzisiro yeHPMC |
|---|---|
| Kupararira | Zvakatsetseka uye zvakafanana |
| Nguva yekuvhura | Hwindo rekushanda rakareba |
| Kubatana | Kugadzikana kwepamusoro kwemukati |
| Katsika kekutsemuka | Njodzi yakaderera |
| Hunhu hwekupedzisira | Magadzirirwo epamusoro akapfava |
Chipimo Chinokurudzirwa cheHPMC muPutty neSkim Coat
Chiyero chinoenderana nerudzi rwemuchina wekubatanidza, kunaka kwemuchina wekuzadza, uye kusimba kwechinangwa.
| Kushandiswa | Chipimo Chakajairika |
|---|---|
| Simende yemadziro | 0.30% – 0.50% |
| Jasi remukati rakarukwa | 0.25% – 0.45% |
| Jasi rejira regypsum | 0.20% – 0.35% |
Kugadziriswa kwemunda kunokurudzirwa zvichienderana nemamiriro ekunze uye kunyudzwa kwevhu.
Gwaro Rekusarudza Giredhi reViscosity
- Kusviba kwepakati nepakati: kuyerera kuri nani uye kuenzana
- Kusviba kwakanyanya: kuramba kwakasimba kwekudonha kwemvura
- Viscosity yakanyanya: muviri wakanyanya wezvikamu zvakakora
Kusviba kwakanyanya kunowanzo shandiswa pakushandisa putty pamadziro, nepo skim coat inogona kushandisa magiredhi ari pakati nepakati kusvika epamusoro zvichienderana nekunzwa kwechinangwa.
Maitiro Akanakisisa Ekugadzira
- Musanganiswa wakaoma weHPMC zvakaenzana nemafillers
- Dzivisa kudira mvura zvakananga pamusoro pemapombi eupfu
- Bata pamwe chete neRDP kuti uvandudze kunamira kwemuchina
- Edza kukwenya kunzwa uye nguva yakasununguka pamwe chete
- Gadzirisa zvichienderana nehukuru hwe calcium carbonate particle
Mibvunzo Inowanzo bvunzwa: Mashandisirwo eHPMC muWall Putty neSkim Coat
Sei HPMC ichiwedzerwa kumadziro eputty?
HPMC inovandudza kuchengetedza mvura, kukwenya kutsvedzerera, kuramba kudonha, uye kunaka kwekupedzisa pamusoro.
Ko HPMC inokanganisa kutsvedzerera kwepamusoro pe putty here?
Ehe. Kusarudza mhando chaiyo kunobatsira kugadzira nzvimbo yakanaka uye yakafanana.
Chii chinoitika kana putty isina HPMC?
Inogona kuoma nekukurumidza, kutsemuka zviri nyore, uye kusashanda zvakanaka panguva yekuisa.
Mhedziso
Hydroxypropyl methylcellulose chinhu chinobatsira zvikuru mumadziro epurasitiki uye masisitimu epurasitiki. Mabasa ayo akawanda - anosanganisira kuchengetedza mvura, kudzora rheology, kuramba kudonha kwemvura, uye kuvandudza kupedzisa - zvinoita kuti ive yakakosha pakugadzira zvinhu zvekupedzisa zvemhando yepamusoro. Nekusarudza kwakakodzera viscosity uye kudzora dosage, HPMC inobvumira mafomula akasimba uye mhedzisiro yepamusoro yekushandisa panzvimbo.
