Chii chinonzi dry mix mortar composition?

Dry musanganiswa dhaka chinhu chisati chasanganiswa, chagadzirira-kushandisa chinosanganisira musanganiswa wesimende, jecha, uye zvimwe zvinowedzera, zvakaita seraimu, maajenti anochengeta mvura, uye anopinza mhepo. Inoshandiswa sechisungo chekubatanidza kune masonry uye plastering application.

Iko kuumbwa kweiyo yakaoma musanganiswa dhaka kunoenderana nerudzi rwekushandisa kwairi kuitirwa. Kazhinji, kuumbwa kweiyo yakaoma musanganiswa dhaka kunosanganisira zvinotevera zvikamu:

Simende: Simende ndiyo inonyanya kusunga mudhaka yakaoma uye ndiyo inonyanya kudhura. Iyo inowanzo umbwa nePortland simende, inova musanganiswa we calcium, silica, alumina, uye iron oxide. Huwandu hwesimende hunoshandiswa mune yakaoma musanganiswa dhaka huchasiyana zvichienderana nekushandiswa uye inodiwa simba redhaka.

Jecha: Jecha ndiro chikamu chechipiri chinonyanya kukosha mumatope akaoma. Inoshandiswa kupa huwandu uye simba kune dhaka. Saizi uye rudzi rwejecha rinoshandiswa zvinoenderana nekushandiswa uye inodiwa simba redhaka.

Lime: Lime inowedzerwa kune yakaoma musanganiswa dhaka kuti iwedzere kushanda kwayo uye kuderedza shrinkage. Inobatsirawo kuderedza huwandu hwemvura inodiwa pakusanganiswa uye inovandudza kukwanisa kwedhaka kusunganidza ne substrate.

Mvura-Kuchengetedza Agents: Mvura-inochengetedza vamiriririCellulose etherszvinowedzerwa kune yakaoma mix mortar kuti ibatsire kuchengetedza unyoro uye kuderedza huwandu hwemvura inodiwa pakusanganiswa. Aya maajenti anowanzo kuumbwa nemapolymer kana zvimwe zvekugadzira zvinhu.

Air-Entraining Agents: Air-entraining agents anowedzerwa kune yakaoma musanganiswa dhaka kuti abatsire kuderedza huwandu hwemhepo inoputika mudhaka. Izvi zvinobatsira kuvandudza simba redhaka uye kushanda.

Additives: Zvakasiyana-siyana zvinowedzera zvinogonawo kuwedzerwa kune yakaoma musanganiswa dhaka kuvandudza kushanda kwayo. Izvi zvinowedzera zvinogona kusanganisira plasticizers, accelerators, retarders, uye kudzivirira mvura.

Iyo chaiyo yekuumbwa kweiyo yakaoma musanganiswa dhaka ichasiyana zvichienderana nekushandiswa uye inodiwa simba redhaka. Zvakakosha kutaurirana nenyanzvi usati washandisa dry mix mortar kuti uone kuti zvikamu zvakakodzera zvinoshandiswa pabasa racho.
