Nekuenderera mberi kwekuvandudza tekinoroji yekuvaka yemazuva ano, External Insulation uye Finish System (EIFS) yave mhinduro yakakosha mumunda wezvivakwa zvekuchengetedza simba. Kuenderera mberi nekuvandudza mashandiro eEIFS, kushandiswa kwehydroxypropyl methylcellulose (HPMC)iri kuwedzera kukosha. HPMC haingogadzirisi kuita kwekuvaka chete, asi zvakare inosimudzira kusimba uye kuchengetedza simba kweiyo system.
Nheyo yekushanda nematambudziko eEIFS
EIFS inoumbwa sisitimu inobatanidza kunze kwemadziro ekudzivirira uye kupedzisa mabasa. Iyo inonyanya kubatanidza mapenera ekudzivirira, anonamira, akasimbisa mesh jira, base coating uye yekushongedza pamusoro pekushongedza. EIFS ine yakanakisa kupisa kwekupisa kwekuita uye huremu hunhu, asi inotarisanawo nemamwe matambudziko ehunyanzvi mune anoshanda maapplication, akadai seasina kukwana anonamira ekuvaka kuita kwekuvaka, kupemha kwekuvhara, uye kunyudza mvura kunyudza. Aya matambudziko anokanganisa zvakananga kusimba kwese kwehurongwa. zvepabonde uye aesthetics.
Performance maitiro eHPMC
HPMC ndeyepamusoro-inoshanda cellulose ether inozivikanwa nekunaka kwayo kukora, kuchengetedza mvura uye kugadzirisa zvivakwa mune zvekuvaka. Basa rayo guru muEIFS rinosanganisira:
Kuvandudzwa kwekuchengetwa kwemvura: HPMC inosimudzira zvakanyanya simba rekuchengetedza mvura yebhainda uye yekuputira, ichiwedzera nguva yekushanda yekuvaka, uku ichiona kuti simende-yakavakirwa zvinhu zvakaringana hydrate panguva yekuomeswa kwekuita kudzivirira kusakwana simba kana kuputika kunokonzerwa nekukurumidza kurasikirwa kwemvura.
Kugadziriswa kwekuita kwekuvaka: HPMC inovandudza rheological zvimiro zvebhainda uye inowedzera yayo anti-sag kuramba, ichiita iyo coating iri nyore kuisa uye ine kupararira kwakanaka, nekudaro inovandudza kuvaka uye kunaka.
Kuwedzerwa simba rekubatanidza: Iyo yunifomu yekugovera yeHPMC inogona kukwirisa viscosity uye kunamatira kweanonamira, ichigadzira chisungo chakasimba pakati pebhodhi rekudzivirira uye madziro.
Kuvandudzwa kwekurambana kwekupwanyika: Nekuwedzera kuchinjika kwedhaka, HPMC inodzivirira inovhara kubva pakutsemuka nekuda kwekushanduka kwekushisa kana base layer deformation.
Zvakananga mashandisirwo eHPMC muEIFS
MuEIFS, HPMC inonyanya kushandiswa mune zvinotevera zvinhu:
Bonding dhaka: Mushure mekuwedzera HPMC, iyo yekubatanidza dhaka ine zvirinani kushanda uye kunamatira, kuve nechokwadi chekuti bhodhi rekudzivirira harizochinji panguva yekuvaka.
Reinforcement layer mortar: Kuwedzera HPMC kune yekusimbisa layer kunogona kuvandudza kuomarara uye kutsemuka kuramba kwedhaka, uye panguva imwechete inosimudzira iyo yekubikira yefiberglass mesh.
Decorative surface coating: Iyo inochengetedza mvura uye yakakora zvimiro zveHPMC inoita kuti iyo yekushongedza yakashongedzwa iwedzere kuenzana uye pendi mhedzisiro iri nani, uku uchiwedzera nguva yekuvhura uye kuderedza kukanganisa kwekuvaka.
Kuvandudzwa kwekuita kwekuvaka
Nekushandisa HPMC muEIFS, kuita kwechivako kunovandudzwa pabhodhi rese:
Kuwedzeredzwa kwesimba rekuchengetedza simba: Iko kusungirirana kwakasimba pakati pebhodhi rekudzivirira uye madziro kunoderedza kupisa kwebhiriji mhedzisiro, uye kugovera yunifomu kweHPMC kunovimbisa kutendeseka uye kupisa kwekushisa kwekuita kwedhaka redhaka.
Yakavandudzwa kusimba: Iyo yakagadziridzwa dhaka uye coating inopokana nekutsemuka uye mamiriro ekunze, zvakanyanya kuwedzera hupenyu hwesevhisi yehurongwa.
Kuvandudza kushanda kwekuvaka: HPMC inonatsiridza zvakanyanya mashandiro ekuvaka, ichiita kuti maitiro ekuvaka anyatsoita uye nemazvo, uye kuderedza mutengo wekugadzirisa zvakare.
Yakakwenenzverwa chitarisiko chemhando: Iyo yekushongedza yakashongedzwa yakapfava uye ruvara rwakanyanya yunifomu, zvichiita kuti chivakwa chiratidzike chakanaka.
Sekuwedzera kwakakosha muEIFS,HPMCinobatsira kukwidziridza sisitimu nekuita kwayo kwakanakisa, ichipa mhinduro dzinoshanda uye dzenguva refu dzezvivakwa zvemazuva ano zvinochengetedza simba. Mune ramangwana, sezvo indasitiri yekuvaka ichiramba ichiwedzera zvinodiwa pakuita kwepamusoro uye kusimba, tarisiro yekushandiswa kweHPMC muEIFS ichave yakakura.
