1. Nhanganyaya kuHPMC
Hydroxypropyl methylcellulose (HPMC) isiri-ionic cellulose ether, iyo inonyanya kugadzirwa kubva kune yakasikwa cellulose kuburikidza nekugadzirisa kemikari. HPMC ine mvura yakanaka solubility, film-forming properties, thickening properties uye adhesive properties, saka inoshandiswa zvakanyanya mukuvaka zvinhu, kunyanya musimende-based building material mortars.
2. Basa reHPMC mune simende-based mortar
Kuomesa mhedzisiro: HPMC inogona kuwedzera zvakanyanya kuenderana uye viscosity yedhaka uye kugadzirisa mashandiro ekuvaka. Nokuwedzera kubatanidzwa kwedhaka, inodzivirira dhaka kubva pakuyerera uye kuisa panguva yekuvaka.
Kuchengetedza mvura mhedzisiro: HPMC ine yakanakisa kuchengetedza kwemvura kuita, iyo inogona zvinobudirira kudzivirira nekukurumidza kurasikirwa kwemvura mudhaka uye kuwedzera nguva ye hydration ye simenti, nekudaro ichivandudza simba uye kusimba kwedhaka. Kunyanya mukupisa kwepamusoro uye nzvimbo dzakaderera dzehunyoro, kuchengetedza kwayo mvura kunonyanya kukosha.
Kuvandudza mashandiro ekuvaka: HPMC inogona kuita kuti dhaka rive nekushanda kwakanaka uye lubricity, kufambisa kuvaka, uye kugadzirisa basa rekuvaka. Panguva imwecheteyo, inogona kuderedza kuputika uye kutsemuka panguva yekuvaka uye kuve nechokwadi chekuvaka.
Anti-sag: Panguva yekuvaka madziro emadziro, HPMC inogona kuvandudza iyo anti-sag yedhaka uye kudzivirira dhaka kubva pakutsvedza panzvimbo yakamira, zvichiita kuti kuvaka kuve nyore.
Shrinkage kuramba: HPMC inogona kunyatso kudzikisa kuoma uye kunyorova shrinkage yedhaka, kunatsiridza kutsemuka kwedhaka, uye kuve nechokwadi chekuti pamusoro pedhaka revhu mushure mekuvakwa kwakatsetseka uye kwakanaka.
3. Chiyero uye kushandiswa kweHPMC
Kuyerwa kweHPMC mudhaka-simende inowanzoita 0.1% kusvika 0.5%. Iyo chaiyo dosage inofanirwa kugadziridzwa zvinoenderana nerudzi uye kuita zvinodiwa zvedhaka. Paunenge uchishandisa HPMC, sanganisa nehupfu hwakaoma kutanga, wobva waisa mvura wozunza. HPMC ine solubility yakanaka uye inogona kukurumidza kuparadzirwa mumvura kuita yunifomu colloidal mhinduro.
4. Kusarudzwa uye kuchengetwa kweHPMC
Sarudzo: Pakusarudza HPMC, iyo yakakodzera modhi uye maratidziro anofanirwa kusarudzwa zvinoenderana nezvinodiwa zvedhaka. Mhando dzakasiyana dzeHPMC dzine misiyano mukunyungudika, viscosity, kuchengetwa kwemvura, nezvimwewo, uye inofanirwa kusarudzwa zvichienderana nemamiriro chaiwo ekushandisa.
Kuchengeta: HPMC inofanira kuchengetwa munzvimbo yakaoma, ine mhepo, kure nehunyoro uye tembiricha yepamusoro. Paunenge uchichengetedza, kutarisisa kunofanira kubhadharwa pakusunga chisimbiso kudzivirira kusangana nehunyoro mumhepo, izvo zvinogona kukanganisa kuita kwayo.
5. Mienzaniso yekushandisa yeHPMC mune simende-based mortar
Ceramic tile adhesive: HPMC inogona kuwedzera zvakanyanya simba rekubatanidza uye kuvandudza mashandiro ekuvaka mumatairi e ceramic adhesives. Yayo yakanaka kuchengetedza mvura uye thickening zvivakwa zvinogona kudzivirira zvinobudirira tile yekunamatira kubva pakudonha uye kurasikirwa panguva yekuvaka.
Ekunze madziro ekudzivirira dhaka: HPMC mune yekunze madziro evhavha dhaka inogona kuvandudza kunamatira uye kuchengetwa kwemvura kwedhaka, kudzivirira dhaka kubva pakuoma uye kubuda kunze panguva yekuvaka nekugadzirisa, uye kugadzirisa kusimba uye kugadzikana kwekunze kwemadziro ekudzivirira system.
Kuzvimisa-leveling dhaka: HPMC mudhaka rekuzvimisa-leveling inogona kuvandudza kuyerera uye kuzvidzora kwekuita kwedhaka, kuderedza kugadzirwa kwemabhuru, uye kuve nechokwadi kudzika uye kutsetseka kwevhu mushure mekuvaka.
6. Tarisiro yeHPMC mune simende-based mortar
Nekuenderera mberi kwekusimudzira indasitiri yekuvaka, kushandiswa kwesamende-based dhaka rekuvaka kuri kuramba kuchipararira, uye zvinodiwa pakuita kwayo zviri kuramba zvichikwira nekukwira. Sekuwedzera kwakakosha, HPMC inogona kuvandudza zvakanyanya mashandiro edhaka uye kusangana nezvinodiwa zvekuvaka zvivakwa zvemazuva ano. Mune ramangwana, nekufambira mberi kwehunyanzvi uye kudiwa kwemusika, tarisiro yekushandiswa kweHPMC mune simende-yakavakirwa dhaka ichave yakakura.
Kushandiswa kweHPMC mune simende-yakavakirwa dhaka kwakavandudza zvakanyanya kuita kwekuvaka uye yekupedzisira mhedzisiro yedhaka. Nekuwedzera huwandu hwakakodzera hweHPMC, kushanda, kuchengetedza mvura, kunamatira uye kutsemuka kuramba kwedhaka kunogona kuvandudzwa zvinobudirira, kuve nechokwadi chekuvaka uye kusimba. Pakusarudza nekushandisa HPMC, kuenzanirana kwakanaka uye manejimendi esainzi inofanirwa kuitwa zvinoenderana nezvinodiwa zvekushandisa kuti ipe kutamba kwakazara kuita kwayo kwepamusoro uye kusangana nezvinodiwa zvakasiyana zvekuvaka kuvaka.
