Masonry chinhu chakakosha uye chakakosha chekuvaka chave chiripo kwemazana emakore. Zvinosanganisira kushandisa zvidhinha, matombo, uye zvimwe zvinhu kugadzira zvivakwa zvakasimba uye zvakasimba. Kuti ive nechokwadi chemhando yepamusoro yemasonry mortar, zvakasiyana-siyana zvinowedzera zvinoshandiswa kuwedzera simba rayo uye kushanda. Imwe yekuwedzera yakadaro i cellulose ether, iyo yakawanikwa ichishanda mukusanganisa aggregate masonry mortars. Iri bepa rinokurukura zvivakwa uye zvakanakira cellulose ether yakasanganiswa aggregate masonry mortar.
Cellulose ethers inotorwa kubva kumiti yemiti uye inowanzoshandiswa mumunda wekuvaka sekuwedzera kune simende-based kuvaka zvinhu. Yakagadzirwa kubva kune yakasikwa cellulose iyo yakagadziridzwa kemikari kuti iwedzere zvimiro zvayo. Cellulose ether ipolymer inonyungudika mumvura inogona kuwedzerwa pamatanho akasiyana ekugadzirira dhaka kuti ivandudze mashandiro edhaka. Kune mhando dzakasiyana dze cellulose ethers, kusanganisira methylhydroxyethylcellulose (MHEC), ethylhydroxyethylcellulose (EHEC), uye hydroxyethylcellulose (HEC), pakati pevamwe.
Kuita kwe cellulose ether yakasanganiswa aggregate masonry mortar
Vandudza kushanda
Imwe yemabhenefiti makuru ekushandisa cellulose ethers mune yakasanganiswa aggregate masonry mortars inovandudzwa kushanda. Cellulose ethers inoshanda semafuta, inoderedza kukweshana pakati pedhaka nezvimwe zvinhu. Izvi zvinoita kuti dhaka rive nyore kupararira, kuderedza nguva yekuvaka uye kuwedzera kubereka. Mukuwedzera, cellulose ether inogona kuwedzera kuwirirana kwemusanganiswa, zvichiita kuti kugoverwa kwevhu kuve nyore uye yunifomu.
kuwedzera kuchengetwa kwemvura
Cellulose ether is hydrophilic, zvinoreva kuti ine hukama hwemvura. Kana yawedzerwa kune yakasanganiswa aggregate masonry mortar, inogona kuwedzera kuchengetwa kwemvura kwedhaka. Izvi zvinobatsira kuchengetedza dhaka rakanyorova kwenguva yakareba, izvo zvakakosha pakurapa. Kurapa kwakakodzera kunovimbisa kuti dhaka rinosvika pakusimba kwayo, zvichiita kuti rive rakasimba uye rinogara kwenguva refu.
kuderedza shrinkage
Imwe bhenefiti yekushandisa cellulose ethers mune yakasanganiswa aggregate masonry mortars inoderedzwa shrinkage. Shrinkage inoitika apo dhaka raoma uye rinorasikirwa nehunyoro, zvichiita kuti ridzike. Izvi zvinogona kutungamirira kune kuputika uye zvimwe zvikanganiso muhutano hwakapedzwa. Cellulose ethers inobatsira kuderedza kuwanda kwemvura inoputika mudhaka, nokudaro kuderedza shrinkage nekuvandudza hutano hwose hwepurojekiti yakapedzwa.
kuwedzera kunamatira
Kubatana kwakanaka pakati pematope uye masonry units kwakakosha kune yakasimba uye yakasimba chimiro. Cellulose ethers inovandudza kusungirirwa kwedhaka kuburikidza nekubatanidza nesement particles. Izvi zvinowedzera kunamatira zvinhu zvedhaka, zvichiita kuti pave nechimiro chakasimba, chakavimbika.
kuwedzera kushanduka
Yakasanganiswa aggregate masonry zvimiro zvinogona kuputika nekuda kwezvinhu zvekunze sekuchinja kwekushisa, humidity, uye mamwe mamiriro ekunze. Iyo cellulose ether mune yakasanganiswa aggregate masonry mortar inobatsira kuvandudza kuchinjika kwedhaka. Izvi zvinoita kuti zvisanyanya kukanganiswa uye zvinobatsira kuchengetedza kurongeka kweprojekiti.
mukupedzisa
Muchidimbu, kune akati wandei mabhenefiti ekushandisa cellulose ether mune yakasanganiswa aggregate masonry madhaka. Inovandudza kushanda, inowedzera kuchengetedza kwemvura, inoderedza shrinkage, inowedzera kunamatira uye inovandudza kushanduka. Kana ikashandiswa nemazvo, cellulose ethers inogona kuvandudza huwandu hwese uye kusimba kweakasanganiswa aggregate masonry zvimiro. Iyo ishamwari yezvakatipoteredza uye inodhura-inoshanda yekuwedzera iyo inogona kushandiswa mumhando dzakasiyana dzezvivakwa zvekuvaka. Naizvozvo, makondirakiti nevavaki vanofanirwa kufunga nezve kushandisa cellulose ether mune yakasanganiswa aggregate masonry mortars.
