suma:
Dry mix mortars dzakakurumbira muindastiri yekuvaka nekuda kwekureruka kwekushandisa, yakagadziridzwa mhando uye nguva inoshanda.Zvakasiyana-siyana zvekuwedzera zvinoita basa rakakosha mukuvandudza mashandiro edhaka rakaoma-musanganiswa, uye chimwe chezvinowedzera zvinozivikanwa ndeye hydroxypropyl methylcellulose (HPMC).Iyi polymer inosiyana-siyana inoshandiswa zvakanyanya mumadhaka akaoma musanganiswa kubatsira kuvandudza kushanda, kunamatira uye kuita kwedhaka rese.
Kemikari chimiro uye zvivakwa zveHPMC:
Hydroxypropylmethylcellulose inotorwa kubva kune cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro.Iyo kemikari chimiro cheHPMC chinoratidzwa nekuvapo kwehydroxypropyl uye methyl mapoka pane cellulose musana.Ichi chakasarudzika chimiro chinopa HPMC chaiyo zvivakwa, ichiita kuti ive yakakodzera kune akasiyana maapplication muindasitiri yekuvaka.
Zvinhu zvakakosha zveHPMC zvinosanganisira:
Kuchengeta mvura:
HPMC ine yakanakisa kuchengetedza mvura, kuve nechokwadi chekuti dhaka rinoramba richishandiswa kwenguva yakareba.Ichi chivakwa chakakosha kudzivirira dhaka kubva pakuoma nguva isati yakwana uye inobvumira kushandiswa kuri nani pane dzakasiyana nzvimbo.
Kukobvura kugona:
HPMC inoshanda seyakakora uye inobatsira kuvandudza kuenderana uye kushanda kwedhaka.Izvi zvinonyanya kubatsira mumashandisirwo akatwasuka uko dhaka rinoda kunamatira kumusoro pasina kusagika.
Natsiridza adhesion:
Kuvapo kweHPMC kunowedzera kunamatira kwedhaka kune akasiyana substrates, kukurudzira zvirinani kusungirirwa uye kusimba kweiyo yekupedzisira chimiro.
Seta nguva yekudzora:
Nekunyatsogadzirisa mhando uye huwandu hweHPMC mune yakaoma musanganiswa dhaka resipi, nguva yekumisikidza yedhaka inogona kudzorwa.Izvi zvinobvumira mapurojekiti ekuvaka kuti achinjike uye achinje kune zvakasiyana zvinodiwa uye mamiriro ezvakatipoteredza.
Flexibility uye crack resistance:
HPMC inopa kuchinjika kune dhaka, ichidzikisa mukana wekutsemuka nekuvandudza kusimba kwese.Izvi zvinonyanya kukosha mumashandisirwo apo chimiro chinoiswa pasi pemasimba ane simba kana shanduko yekushisa.
Kushandiswa kweHPMC mune yakaoma yakasanganiswa dhaka :
Tile adhesive:
HPMC inowanzoshandiswa mumatairi adhesives kuvandudza kunamatira, kuchengetedza mvura uye kushanda.Iyo polymer inovimbisa chisungo chakasimba pakati pe tile uye substrate, nekudaro kuwedzera hupenyu hurefu hweiyo tile pamusoro.
Plastering mortar:
Mukupura matope, HPMC inobatsira kuvandudza kushanda uye kunamatira kwemusanganiswa.Iyo polymer inobatsira kuwana yakatsetseka uye inowirirana plaster pamusoro uku ichideredza njodzi yekutsemuka.
Masonry dhaka:
HPMC inoshandiswa mumasonry madhaka kusimudzira kuchengetedza kwemvura, kushanda uye kunamatira.Kuvandudzwa kwekubatanidza zvivakwa kunoita kuti zvivakwa zvemasoni zvisimbe uye zvakanyanya kusimba.
Self-leveling compounds:
Iyo mvura-yekuchengetedza uye kukora zvimiro zveHPMC zvinoita kuti ive yakakodzera kushandiswa mune yekuzvimiririra makomisheni.Aya makomisheni anovimbisa nzvimbo yakatsetseka uye inogona kushandiswa mune dzakasiyana siyana dzekuvaka.
Seam filler:
HPMC inosanganisirwa mune caulk kuvandudza kuchinjika uye kunamatira.Izvi zvinonyanya kukosha kune majoini anofambisa kufamba uye kuwedzera kwekupisa.
Kudzora Hunhu uye Kuenderana:
Kuve nechokwadi chemhando uye kuenderana kweHPMC mune yakaoma-musanganiswa dhaka kwakakosha kuti uwane kuita kunodiwa.Matanho ekudzora emhando anosanganisira kuyedza mapolymers emaparamendi akadai seviscosity, hunyoro hwemukati uye saizi yekugovera.Zvidzidzo zvekuenderana zvinofanirwa kuitiswa kuongorora kudyidzana pakati peHPMC uye zvimwe zvinongedzo mukuumbwa kwevhu kuti ive nechokwadi che synergistic mhedzisiro pasina kukanganisa kwakashata.
Zvemamiriro ekunze:
HPMC inoonekwa seine hushamwari kwezvakatipoteredza sezvo ichitorwa kubva kune zvinogonekazve zviwanikwa.Iyo biodegradability yeHPMC inova nechokwadi chekuti kushandiswa kwayo mukuvaka zvikumbiro hakuzove nekukanganisa kwenguva refu kune zvakatipoteredza.
mukupedzisa:
Hydroxypropyl methylcellulose inoshandiswa zvakasiyana-siyana uye yakakosha mukuwedzera mune yakaoma musanganiswa wevhu munda.Musanganiswa wayo wakasarudzika wezvivakwa, zvinosanganisira kuchengetedza mvura, kukora masimba uye kuwedzeredzwa kunamatira, inoita kuti ive chinhu chakakosha mumhando dzakasiyana dzekuvaka.Sezvo indasitiri yekuvaka ichienderera mberi nekushanduka, basa reHPMC mukuvandudza mashandiro uye kusimba kwemavhu-musanganiswa wematope angangowedzera, nekudaro zvichipa maitiro ekuvaka anoshanda uye akasimba.
