Hydroxypropyl Methylcellulose (HPMC) muZvishandiso zvekuvaka

Hydroxypropyl Methylcellulose (HPMC)imusanganiswa unoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, uye uripo zvakanyanya muchikamu chekuvaka. Iyi polymer yekugadzira inotorwa kubva ku cellulose inoshandiswa zvakawanda nekuda kwehunhu hwayo hwakasiyana, kusanganisira kuchengetedza mvura, kugona kwayo kukora, uye hunhu hwekunamira. Muzvinhu zvekuvaka, HPMC inoshanda sechinhu chakakosha chinosimudzira mashandiro uye mashandiro ezvigadzirwa zvakasiyana-siyana.

Kunzwisisa HPMC:

HPMC, inozivikanwawo sehypromellose, ipolymer inonyungudika mumvura inotorwa kubva mu cellulose kuburikidza nekuchinja kwemakemikari. Kugadzira uku kunosanganisira kurapa cellulose nepropylene oxide nemethyl chloride, zvichiita kuti mapoka ehydroxyl atsiviwe nemapoka ehydroxypropyl nemethyl. Maitiro aya anowedzera kunyungudika kwemvura yemusanganiswa uye anochinja hunhu hwayo hwepanyama, zvichiita kuti ive yakakodzera kushandiswa kwakasiyana-siyana.

Hunhu hweHPMC:

HPMC ine zvinhu zvakawanda zvinoita kuti ive chinhu chakanakira chekuwedzera muzvinhu zvekuvaka:

Kuchengetedza Mvura: HPMC ine hunhu hwakanaka hwekuchengetedza mvura, zvichiita kuti ive yakakosha mukuvaka zvinhu zvakaita semamortar, marender, uye maplaster. Kugona kwayo kugadzira chimiro chakaita segel kana yakasanganiswa nemvura kunobatsira kudzivirira kurasikirwa nemvura nekukurumidza panguva yekuisa uye kupora, zvichiita kuti zvinhu zvinosimbisa simende zvinyoroveswe zvakanaka.

Kukora: HPMC inoshanda semushonga wekukora unoshanda zvakanaka, ichipa viscosity kune mhinduro uye inovandudza kushanda. Hunhu uhwu hunonyanya kubatsira muma tile glues, grouts, uye ma joint compounds, uko kunoita kuti zvive nyore kushandisa, uye kugona kunamira panzvimbo dzakamira.

Kugadzirwa kweFirimu: Kana yaoma, HPMC inogadzira firimu rinoonekera uye rinochinjika, zvichiwedzera kugara kwenguva refu uye kuramba kwezvipfeko nezvivharo. Kugona uku kugadzira firimu kwakakosha pakudzivirira nzvimbo kubva mukunaya kwemvura, mwaranzi yeUV, uye kukuvara kwemuchina, nokudaro zvichiwedzera hupenyu hwezvinhu zvekuvaka.

Kunamira:HPMCinobatsira pakusimba kwekunama kwezvigadzirwa zvakasiyana-siyana zvekuvaka, zvichiita kuti zvive nyore kubatana pakati pezvinhu zviri pasi uye kusimbisa kusimba kwechimiro chose. Muma tile glues nema plastering compounds, inokurudzira kunamira kwakasimba panzvimbo dzakasiyana-siyana, kusanganisira kongiri, huni, uye ceramics.

Kugadzikana Kwemakemikari: HPMC ine kugadzikana kwakanaka kwemakemikari, ichichengetedza hunhu hwayo pamusoro pemazinga akasiyana-siyana epH netembiricha. Hunhu uhwu hunovimbisa kushanda kwenguva refu uye kugara kwenguva refu kwezvinhu zvekuvaka mumamiriro akasiyana ekunze.

Kushandiswa kweHPMC muZvishandiso zvekuvaka:

HPMC inoshandisa zvakanyanya mukugadzira zvinhu zvakasiyana-siyana zvekuvaka, zvichiita kuti zvishande zvakanaka, zvigare kwenguva refu, uye zvishande zvakanaka:

Madhaka neMadhika: HPMC inowanzo sanganiswa mumadhaka nedhika rakagadzirwa nesimende kuti ivandudze kushanda, kunamira, uye kuchengetedza mvura. Nekudzivirira kurasikirwa nemvura nekukurumidza, inobvumira nguva yakareba yekushanda uye inoderedza njodzi yekutsemuka nekupwanyika panguva yekugayiwa. Pamusoro pezvo, HPMC inowedzera kubatana uye kugara kwenguva refu kwemadhaka, ichivimbisa kushandiswa kwakafanana uye kubatana kuri nani kune substrates.

Zvinonamira Mataira neGrouts: Mumasisitimu ekuisa mataira, HPMC inoshanda sechinhu chakakosha chezvinonamira negrouts. Muzvinonamira, inopa hunhu hwethixotropic, zvichiita kuti zvive nyore kushandisa nekugadzirisa mataira ukuwo ichivimbisa kunamira kwakasimba kune substrates. Muzvinamira, HPMC inowedzera hunhu hwekuyerera kwemvura, ichideredza mukana wekuti pave nevhudzi uye inovandudza chitarisiko chekupedzisira chenzvimbo dzakanamira mataira.

Mapurasita neMastucco: HPMC inoita basa rakakosha mukusimudzira mashandiro emaplasita nestucco mukati nekunze. Nekuvandudza kuchengetedza mvura uye kushanda zvakanaka, inobatsira kushandiswa zviri nyore, inoderedza kutsemuka, uye inowedzera simba rekubatana pakati peplasita nesubstrate. Uyezve, HPMC inobatsira kudzora kudzika nekuderera, zvichikonzera kupera kwakafanana uye kwakasimba.

Masisitimu Ekudzivirira Kunze uye Kupedzisa (EIFS): EIFS inoshandisa manamatiro ne basecoats zvakagadzirwa neHPMC kuti isunge mabhodhi ekudzivirira ku substrates uye inopa kupedzisa kwekunze kunodzivirira. HPMC inoita kuti pamusoro panyoroveswe zvakanaka, inowedzera kunamira, uye inobatsira pakuchinjika uye kuramba kutsemuka kweEIFS coating, nokudaro ichivandudza kushanda kwekupisa uye kuramba kwemamiriro ekunze.

Makonzo Nezvisimbiso: Makonzo nezvisimbiso zvakagadzirwa neHPMC zvinoshandiswa zvakanyanya mukuvaka kuzadza mipata, majoini, uye mitswe mune zvakasiyana-siyana. Mafomu aya anobatsirwa neHPMC's retaining water, adhesion, uye firimu, izvo zvinobatsira kugadzira zvisimbiso zvinogara kwenguva refu uye zvinodzivirira mamiriro ekunze, kudzivirira kupinda kwehunyoro nemhepo.

kubuda kwemvura.

Zvigadzirwa zveGypsum: Muzvinhu zvekuvaka zvakagadzirwa negypsum zvakaita semaplaster, majoint compounds, uye self-leveling underlayments, HPMC inoshanda semugadziri werheology uye muchengeti wemvura. Inovandudza kushanda, inoderedza kudzika, uye inowedzera kubatana pakati pezvidimbu zvegypsum, zvichikonzera kupera kwakapfava uye kuderera kwekutsemuka.

Hydroxypropyl Methylcellulose (HPMC)inoita basa guru muindasitiri yekuvaka, ichibatsira muzvinhu zvakasiyana-siyana uye mashandisirwo azvo. Musanganiswa wayo wakasiyana wehunhu hwayo, kusanganisira kuchengetedza mvura, kukora, kunamira, uye kugadzirwa kwefirimu, unowedzera kushanda, kugara kwenguva refu, uye kushanda zvakanaka kwezvigadzirwa zvekuvaka kubva kumamortar uye marender kusvika kumaglues nezvisimbiso. Sezvo chikamu chekuvaka chichienderera mberi nekushanduka, HPMC inotarisirwa kuramba iri chikamu chakakosha, ichitungamira hunyanzvi uye ichivandudza mhando yenzvimbo dzakavakwa pasi rese.
