Mamiriro ekunze ematope:
tsananguro:
Efflorescence ndiyo chena, powdery deposit iyo dzimwe nguva inoonekwa pamusoro pemasonry, kongiri kana dhaka.Izvi zvinoitika kana munyu unonyungudika mumvura unonyungudika mumvura mukati mechinhu chacho uye wotamira pamusoro, apo mvura inoputika, ichisiya munyu.
chikonzero:
Kupinda Kwemvura: Mvura inopinda mumasonry kana dhaka inogona kunyungudutsa munyu uripo mune izvo zvinhu.
Capillary action: Kufamba kwemvura kuburikidza nemacapillaries mumasonry kana dhaka kunogona kuunza munyu pamusoro.
Kuchinja kwetembiricha: Kuchinja kwematembiricha kunoita kuti mvura iri mukati mechinhu chiwedzere uye chibvumirano, ichikurudzira kufamba kwemunyu.
Improper Mix Ratios: dhaka risina kusanganiswa zvakanaka kana kushandisa mvura ine tsvina kunogona kuunza imwe munyu.
Kudzivirira uye kurapwa:
Maitiro Ekuvaka Akakodzera: Iva nechokwadi chekuyerera kwakaringana uye shandisa nzira dzekuvaka dzakafanira kudzivirira kupinda kwemvura.
Kushandiswa Kwekuwedzera: Zvimwe zvinowedzera zvinogona kuverengerwa mumusanganiswa wedhaka kuti uderedze efflorescence.
Kurapa: Kurapa kwakakwana kwedhaka kunoderedza mukana we efflorescence.
Hydroxypropyl methylcellulose (HPMC):
tsananguro:
Hydroxypropylmethylcellulose (HPMC) i polymer yakagadzirwa kubva mu cellulose.Iyo inowanzoshandiswa muindasitiri yekuvaka seyakakora, inochengetedza mvura mumiriri uye inonamira mumadhaka nezvimwe zvekuvaka.
Basa:
Kuchengeta Mvura: HPMC inobatsira kuchengetedza mwando mudhaka, kudzivirira kuti isaoma nekukasira.
Inovandudza kushanda: Inovandudza kushanda uye kuenderana kwedhaka, zvichiita kuti zvive nyore kubata nekuvaka.
Adhesion: HPMC inobatsira kuvandudza kunamatira pakati pedhaka uye substrate.
Consistency control: Inobatsira kuchengetedza inowirirana dhaka mhando, kunyanya pasi pezvakasiyana mamiriro ezvakatipoteredza.
Vanogona kufambidzana navo:
Nepo HPMC pachayo isingakonzere zvakananga efflorescence, kushandiswa kwayo mumadhaka kunogona kukanganisa efflorescence.Semuyenzaniso, iyo yakagadziridzwa yekuchengetedza mvura zvivakwa zveHPMC zvinogona kukanganisa maitiro ekurapa, zvichigona kuderedza njodzi ye efflorescence nekuona kuomeswa uye kuenderera mberi kwekuoma kwedhaka.
mukupedzisa:
Muchidimbu, hapana hukama hwakananga hwechikonzero pakati pematope emamiriro ekunze uye hydroxypropyl methylcellulose.Nekudaro, kushandiswa kwezvinowedzera zvakaita seHPMC mumadhaka zvinogona kukanganisa zvinhu zvakaita sekuchengetedza mvura uye kurapa, izvo zvinogona kukanganisa zvisina kunanga mukana weiyo efflorescence.Zvinhu zvakasiyana-siyana, zvinosanganisira maitiro ekuvaka, musanganiswa ratios uye mamiriro ezvakatipoteredza, zvinofanirwa kutariswa kudzivirira nemazvo uye kutonga efflorescence mumasonry uye dhaka kunyorera.
