HydroxyPropyl methylcellose (HPMC) inyaya yemiindasitiri yeindasitiri inoshandiswa zvakanyanya muWall putty poda mafomu, kunyanya yemukati uye ekunze application.
HPMC Powder Sumo:
Tsanangudzo uye kuumbwa:
HydroxyPropyl methylcellose, inotaurwa nezvayo se hpmc, yakagadziridzwa cellulose ther yakatorwa kubva kune yakasikwa cellulose. Iyo yakashongedzwa nemakemikari kugadzirisa cellulose, yakaomarara carbohydrate inowanikwa mune zvinodyara masero emadziro. Kugadziridzwa kunosanganisira kuiswa kwehydroxypruppropyl uye methyl mapoka muCellulose chimiro, zvichikonzera poluble uye yakanyanya kudzvanywa polymer.
Zvivakwa zvemuviri uye zvemakemikari:
Solubility: Hpmc inochenesa mumvura, inogadzira mhinduro yakajeka uye isina mavara. Solubility inogona kuchinjirwa nekuchinja iyo degree rekutsiva (DS) panguva yekugadzira maitiro.
Viscosity: HPMC inopa vhiza yakadzorwa uye isingaenderani kumhinduro. Ichi chivakwa chakakosha muWall putty mafomu ezvekuita zvinokanganisa basa rekushanda uye rekushandisa rechinyorwa.
Thermal Gelation: HPMC inoratidza thermal gelation, zvinoreva kuti inogona kuumba gel kana ichipiswa. Ichi chivakwa chakakosha mune zvimwe zvekushandisa apo gelly inodiwa.
Kushandiswa kweHPMC muWall Putty:
Mukati madziro putty:
1. Kubatira uye kuderedza:
HPMC inosimudzira zvinhu zvekubatanidza zvekusungwa kwemukati madziro
HPMC yakagadziridzwa cellulose chimiro chinoumba firimu rakatetepa pamusoro, kupa chisungo chakasimba uye chakasimba.
2. Kugadziriswa uye kusununguka kwekushandisa:
Vhiza yakadzorwa yeHPMC inopa iyo putty yakanaka kwazvo basa, ichibvumira kuti iwaniswe zvakanaka uye zviri nyore nzvimbo yemukati.
Iyo inodzivirira kusekerera uye kudonha panguva yekushandisa uye inovimbisa yunifomu yekubatanidza.
3. Kuchengeta mvura:
HPMC inoita semvura inochengetedza mumiririri, kudzivirira nekukurumidza zvekuvhuvhu wemvura panguva yekuporesa. Izvi zvinobatsira kuvandudza hydration yeiyo putty, zvichikonzera kusimba kuri nani kusimba.
Exterior Wall Putty:
1. Kubata Kwemamiriro ekunze:
HPMC inowedzera kudzikisira kwemamiriro ekunze kweWarus Wall Futties uye anodzivirira kubva pamhedzisiro yakaipa yezuva, mvura uye tembiricha shanduko.
Iyo polymer firimu yakaumbwa neHPMC zviito sechisungo, kudzivirira kupinza zvinyoro-nyoro uye kuchengeta kutendeka kwekucheka.
2. Crack kuramba:
Iko kushanduka kweHPMC kunobatsira kune iyo crack kudzikisira kwekunze kwekunze putty. Iyo inogara iyo substrate kufamba usingakanganisi kutendeka kwekucheka.
Iyi pfuma ndeyekutsoropodza kwekunze kwekushandisa pachena kune kushushikana kwezvakatipoteredza.
3. Kugara:
HPMC inovandudza kujairwa kwakazara kwekunze putty nekuvandudza kupokana kwayo kune abrasion, kukanganisa uye kuratidzwa kwemakemikari.
Iyo firimu yekudzivirira inoumbwa neHPMC inobatsira kuwedzera hupenyu hwekucheka uye kuderedza kukosha kwekuchengetedza nguva zhinji.
Zvakanakira kushandisa HPMC muWall Putty:
1. Unhu hwakagadzikana:
HPMC inovimbisa kuti maWarty Putty mafomu ndeyekuenderana nemhando yekuwirirana uye kusangana zvinodiwa maitiro ekuita.
2. Kuvandudza Kushanda:
Iyo inotorwa vhiza yeHPMC inopa iri nani maitiro ekugadziriswa, kuita kuti maitiro ekushandisa anonyatsobudirira uye mushandisi-ane hushamwari.
3. Simbisa Dhiziri:
Iyo inonamatira zvivakwa zveHPMC inobatsira kune yakanakisa kudiwa, inoona iyo putty inonamatira zvakanaka kune akasiyana siyana eSubstrates.
4. Kuedza:
HPMC iri kuita zvakasiyana uye inogona kushandiswa mune dzakasiyana siyana dzekuumbwa uye dzinogona kugadziriswa kusangana zvakananga zviitiko zvepurojekiti.
Mukupedzisa:
HydroxyPropyl methylcellose (HPMC) poda ndiyo yakakosha musanganiswa mune zvemukati uye kunze kwekunze mari putty mafomula. Zvivakwa zvaro zvakasarudzika, kusanganisira solubility, viscosity kudzora uye firimu-kugadzira kugona, ita kuti ive yakanaka yekuvandudza mashandiro uye kusimba kwemadziro emadziro. Kunyangwe yakaiswa mumuviri kana kunze, madziro ekuisa kune HPMC inopa kusarongeka kwemhando, yakavandudzwa mashandiro ekushandisa uye kudzivirirwa kwenguva refu kubva kune zvakatipoteredza zvinhu. Sezvo indasitiri yekuvaka ichiramba ichishanduka, basa reHPMC mumadziro prewty formation inoramba ichikwanisika kuzadzisa yakakwirira-yemhando uye yakasimba kupedzisa.
