Chii chinonzi hpmc ye gypsum plaster?

1 Nhanganyaya
HPMC (hydroxyprEpyl methyl cellelose) is nonitic cellulose inoshandiswa zvakanyanya muzvivakwa zvekuvaka, kusanganisira gypsum plaster. Semunhu anokosha anoshanda anowedzera, HPMC inovandudza midziyo yekugadzirisa uye maitiro ekushandisa eGypsum mapuranga.

2. Main Properties yeHPMC
HPMC ndeye polymer yakawanikwa yakawanikwa nemakemikari kugadziridzwa kwemasikirwo emusikirwo cellulose. Zvimiro zvayo zvinosanganisira:

Mvura Solubility: HPMC inogona kunyungudika nekukurumidza mumvura inotonhora, kugadzira yakajeka kana zvishoma Milky mhinduro.
Kukakavara: Kugona zvakanyanya kuwedzera zvevisiko zvemhinduro.
Gelling: HPMC ine akasiyana majecha ekugadzira midziyo, uye mhinduro yacho inoregedza fluidity mushure mekutonhora.
Kuchengeta kwemvura: Muzvivakwa zvekuvaka, zvinogona kuvandudza zvinobudirira kuchengetwa kwemvura kwezvinhu uye kuwedzera nguva yekushandisa.
Lubricity: Kuvandudza iyo Lubrication Properties yezvinyorwa kuti vafambise kuvaka uye kushandisa.

3. Basa reHPMC muGypsum Plaster
3.1 Kuvandudza Kuchengetwa Kwemvura
HPMC inowedzera iyo inobata-inobata mari ye gypsum plaster uye inoderedza kukurumidza kwemvura. Izvi zvakakosha kwazvo pakuvaka uye kuumbwa kweGypsum Plaster, sekuchengetwa kwemvura kwakakwana kunoita kuti kuomesa kwunifomu kupfekedzwa kweplaster uye kudzivisa shrinkage uye marara.

3.2 Kuwedzera Adhisheni
HPMC inovandudza bond pakati pe stucco uye substrate. Izvi zvinobatsira kuvandudza musungo simba replaster uye dzinodzivirira kutarisana uye nekukwira, nekukasira kuwedzera hupenyu hwebasa.

3.3 Kuvandudza Kuita Kwekuvaka
HPMC inowedzera iyo viscosity ye gypsum plaster, ichiita kuti zvive nyore kushandisa uye kugadzira yakatsiga. Mukuwedzera, HPMC inosimudzira iyo lubricity ye stucco, ichiita kuti zvive nyore kuti zvishandiso zvekuvaka kushandira, nekukasira kubatsira mukuvaka uye kunaka.

3.4 Dzivirira Sagging
HPMC inovandudza kuenderana uye renherology yeplaster, kudzivirira iyo plaster kubva kugomba uye kusimbisa panguva yekuvaka, nekudaro ichiratidza kutsvedza kwemadziro.

3.5 Wedzera maawa ekuvhura
HPMC inowedzera nguva yakavhurika ye stucco nguva yekuvaka nguva yakawanda yekutema uye kushanda, ichidzivisa kuremara kwekuvaka kunokonzerwa nekushaiwa nguva.

4. Dosage uye kushandiswa kweHPMC
4.1 Dosage Kudzora
MuGypsum Plaster, HPMC inowanzowedzerwa pamazinga pakati pe0,1% uye 0.5%. Izvi zvinoenderana chaizvo nezvakagadzirwa neiyo stucco, zvido zvekushandisa, uye mamiriro ezvinhu epamhepo. Dosage iyo yakanyanya kukwirira kana yakaderera inogona kukanganisa maitiro eStucco, saka kugadzirisa kunoda kuitwa zvichienderana nemamiriro chaiwo.

4.2 Mashandisiro Aungaita
HPMC inofanira kuve yakanyatso kuparadzirwa mune yakaoma hupfu uye ikabva yasanganiswa nezvimwe zvinosanganiswa. Kazhinji panguva yekugadziriswa kweStucco, HPMC inowedzerwa kune iyo yunifomu yakakurudzira gypsum hupfu, saka huwandu hwakakodzera hwemvura hunowedzerwa, uye musanganiswa wakasanganiswa kusvikira yunifomu yekuenderana.

5. Zvakanakira HPMC muGypsum Plaster
5.1 Zvakatipoteredza Dziviriro
HPMC ndeye isiri-ine chepfu, isina-kusvibisa girini yemakemikari. Kunyorera kwayo hakuzove nemhedzisiro yakaipa pane zvakatipoteredza, iyo iri mumutsara neyezvinodiwa nezvekudzivirira zvinodiwa zvezvinhu zvemazuva ano zvekuvaka.

5.2 hupfumi
Nekuda kwekushanda kwakanyanya kweHPMC, huwandu hwayo hwekuwedzera hunogona kuvandudza zvakanyanya kuita kwe gypsum plaster, saka ine mari yakanyanya kuita.

5.3 Kugadzikana
Kuita kweHPMC muGypsum Plaster yakasimba uye haizoshanduke zvakanyanya nekuda kwekuchinja mukushisa uye humidity. Izvo zvakakodzera nzvimbo dzakasiyana siyana dzekuvaka.

6. Inoshanda application kesi
Mukuvaka chaiko, Gypsum Plaster yakawedzera neHPMC yakashandiswa zvakanyanya mumadziro kupurudza, ceiling pendi, kuvaka kuvaka uye mamwe minda. Semuenzaniso, pendi pendi yemukati yezvivakwa, kuwedzera HPMC kuenda kuGypsum Plaster kunogona kudzivirira zvinokwanira mabundu uye matambudziko ekurasikirwa neupfu uye kupa madziro ekupedza madziro ekupedza mhedzisiro.

Iko kushandiswa kweHPMC muGypsum Plaster haina kungovandudza zvivakwa zvemukati zvezvinyorwa, asi zvinovandudzawo hunhu hwekuvaka uye kushanda zvakanaka. Kuchengetwa kwemvura kwayo, kudenha uye zvekuvaka zvinoita chinhu chakakosha chezvinhu zvemazuva ano zvekuvaka. Mune ramangwana, seindasitiri wekuvaka maindasitiri wekuita zvakakwirira-kuita, zvakatipoteredza zvinhu zvinowedzera, tarisiro yekushandisa yeHPMC ichave yakawedzera.
