QualiCell cellulose ether HPMC / MHEC zvigadzirwa zvinogona kuita kuti simende izere hydrated, zvakanyanya kuwedzera kusimba kwekubatanidza, uye zvakare inogona kuwedzera kusimba kwekubatanidza uye kugera kusungirira simba redhaka rakaomarara. Zvichakadaro, inogona kuvandudza zvakanyanya kushanda uye lubricity, kuvandudza zvakanyanya mhedzisiro yekuvaka nekuvandudza kushanda zvakanaka.
Cellulose ether yeMasonry Mortar
Masonry dhaka zvinoreva dhaka rinovakirwa zvidhinha, matombo, uye zvinhu zvebhuroko kuita masonry. Inotamba basa rezvimiro, kongiri uye simba rekufambisa, uye chikamu chakakosha chemasonry simende slurry. Zvidhinha zvesimende zvinoshandiswa kuvaka masonry ane zvinodiwa zvakakwirira zvesimende nharaunda uye simba. Zvidhinha matinji anowanzo shandisa simende dhaka ine giredhi resimba re5 kusvika kuM10; nheyo dzezvidhinha dzinowanzoshandisa dhaka resimende risiri reM5; dzimba dzakaderera kana bungalows dzinogona kushandisa lime mortar; zviri nyore zvekuvaka, lime ivhu dhaka, inogona kushandiswa.
Simende ndicho chinhu chikuru chekuisa dhaka. Masimende anowanzo shandiswa anosanganisira simende, slag simende, pozzolan simenti, fly ash simenti uye composite simenti, nezvimwewo, izvo zvinogona kusarudzwa zvinoenderana nezvinodiwa zvekugadzira, masonry zvidhinha uye simende mamiriro ekunze. Simende yakasimba inogona kusangana nezvinodiwa.
Kusimba kwegiredhi resimende rinoshandiswa mujecha resimende harifaniri kudarika 32.5; giredhi resimba resimende rinoshandiswa musimende yakasanganiswa dhaka harifanire kunge rakakura kupfuura 42.5. Kana iyo simende simba rezinga rakanyanyisa, unogona kuwedzera zvimwe zvakasanganiswa zvinhu. Nokuda kwezvimwe zvinangwa zvakakosha, zvakadai sekugadzirisa majoini uye majoini ezvikamu, kana kusimbiswa kwemaitiro uye kugadziriswa kwezvimedu, simiti yakakura inofanira kushandiswa. Cementitious zvinhu zvinoshandiswa mumasonry dhaka zvinosanganisira simende uye lime. Sarudzo yemhando dzesimende yakafanana neyekongiri. Simende giredhi inofanira kuva 45 nguva giredhi simba dhaka. Kana giredhi resimende rakanyanyisa, huwandu hwesimende hunenge husina kukwana, zvichiita kuti mvura isachengeteke zvakanaka. Lime paste uye slaked lime haingoshandiswe sesement zvinhu, asi zvinonyanya kukosha, ita kuti dhaka rive nekuchengetedza mvura zvakanaka. Fine aggregate Aggregate yakanaka ijecha rechisikigo, uye dhaka rakagadzirwa rinonzi dhaka rakajairwa. Ivhu riri mujecha harifaniri kudarika 5%; apo giredhi resimba riri pasi pem2.5, ivhu yevhu haifaniri kudarika 10%. Hukuru hwesaizi yejecha hunofanirwa kunge huri pasi pe1/41/5 yeukobvu hwedhaka, kazhinji isingadarike 2.5 mm. Sedhaka remagrooves uye plastering, iyo yakakura particle size haipfuuri 1.25 mm. Ukobvu hwejecha hune simba guru pahuwandu hwesamende, kushanda, simba uye shrinkage.
