Mtondo wosakaniza ndi ufa womalizidwa wopangidwa ndi zinthu zosakaniza simenti, zosakaniza, zodzaza, ndi zowonjezera zosiyanasiyana zogwira ntchito moyenera mufakitale. Pakumanga, ungagwiritsidwe ntchito pongowonjezera madzi ndi kusakaniza. Kuti ukwaniritse magwiridwe antchito osiyanasiyana komanso zofunikira pakulimba, mtondo wosakaniza nthawi zambiri umafuna kuwonjezera zowonjezera zingapo, zomwe ma cellulose ether ndi amodzi mwa zowonjezera zofunika kwambiri za organic polymer.
1. Kugawa Zowonjezera Zofanana pa Dry-mix Mortar
1.1. Zokhuthala Zosunga Madzi
Zitsanzo zodziwika bwino zikuphatikizapohydroxypropyl methylcellulose (HPMC),hydroxyethyl methylcellulose (HEMC)ndihydroxyethyl cellulose (HEC).
Ntchito Zazikulu: Kukonza kusunga madzi a m'matope, kupewa kutuluka magazi, kukulitsa nthawi yotsegulira, komanso kukonza kukhazikika ndi thixotropy panthawi yomanga.
1.2. Zobwezera ndi Zotsatsira
Zotsalira (monga citric acid ndi tartaric acid) zimachedwetsa kukhazikitsa ndipo ndizoyenera kumangidwa kutentha kwambiri kapena kugwiritsidwa ntchito pamlingo waukulu. Zotsatsira mphamvu (monga chloride salts ndi aluminiyamu salts) zimathandizira kukhazikitsa ndi kuuma pa kutentha kochepa.
1.3. Zothandizira Kulowetsa Mpweya
Ma lignin sulfonates ndi alkyl sulfonates omwe amagwiritsidwa ntchito kwambiri ndi awa. Amathandiza kuti matope agwire bwino ntchito, asagwere chisanu, komanso kuti asagwedezeke mosavuta pogwiritsa ntchito thovu laling'ono.
1.4. Zinthu Zochepetsa Madzi
Makamaka zinthu zochokera ku naphthalene ndi polycarboxylic acid, zimachepetsa kugwiritsa ntchito madzi ndikuwonjezera mphamvu ndi kuchuluka kwa matope.
1.5. Ufa wa Polima Wotha Kumwazikanso (RDP)
Zimathandiza kuti matope azigwira ntchito mosinthasintha, molimba, komanso mosasweka. Amagwiritsidwa ntchito kwambiri mu zomatira za matailosi, makina oteteza makoma akunja, komanso kukonza matope.
1.6. Zowonjezera Zina Zogwira Ntchito
Zimaphatikizapo zoletsa mildew, zochotsa madzi m'thupi, ufa woopsa m'madzi, ndi ma starch ether okhuthala. Zowonjezera izi zimasankhidwa kutengera momwe matope amagwiritsidwira ntchito.
2. Njira Yogwirira Ntchito ya Cellulose Ethers mu Dry-Mix Mortars
Ma cellulose ether ndi gulu la ma polima osakhala a ionic osungunuka m'madzi omwe amagwiritsidwa ntchito kwambiri m'makina osiyanasiyana a matope osakanikirana ndi madzi. Njira zake zazikulu zogwirira ntchito ndi izi:
2.1. Kusunga Madzi
Mamolekyu a ether a cellulose amayamwa ndikutseka m'madzi osakanikirana, zomwe zimachepetsa kutayika kwake ku substrate ndi mpweya, zomwe zimapangitsa kuti zinthu zomangira simenti zikhale ndi nthawi yokwanira yothira madzi, motero zimawonjezera mphamvu ya matope.
2.2. Kukhuthala ndi Kulamulira Kuzungulira kwa Mafupa
Ma cellulose ether amapanga yankho lolimba m'madzi, zomwe zimapangitsa kuti matope azikhala onyowa komanso omatirira bwino, zomwe zimapangitsa kuti asagwedezeke (kukana kutsika) akagwiritsidwa ntchito pamalo oyima. Kuphatikiza apo, ma cellulose ether abwino kwambiri amakhala ndi thixotropy yabwino kwambiri, zomwe zimathandiza kuti zinthu ziyende bwino komanso kuti zinthu ziyende bwino.
2.3. Kugwira Ntchito Bwino
Mphamvu yogwirizana ya kusunga madzi ndi mphamvu ya rheological imatsimikizira kuti nthawi yogwira ntchito ndi yayitali komanso kumveka bwino kwa matope, kuchepetsa kutopa mukamagwiritsa ntchito.
2.4. Kukhazikika Kowonjezereka
Kuchepetsa kulekanitsa ndi kutuluka kwa magazi kwa zinthu zomangira ndi simenti kumathandizira kuti matope azikhala ofanana komanso kuti ntchito yomanga ikhale yolimba.
3. Kugwiritsa Ntchito Ma Cellulose Ethers Mu Ma Mortar Osiyanasiyana Osakanikirana ndi Dry-Mix
3.1. Mtondo wa Maziko ndi Mtondo wa Pulasitiki
Kusunga madzi ambiri komanso kugwira ntchito bwino ndikofunikira. Ma cellulose ether amatha kuchepetsa kusweka ndi kusweka, komanso kumamatira bwino.
3.2. Chomatira cha Matailosi
Makhalidwe abwino kwambiri oletsa kugwa komanso nthawi yayitali yotseguka amafunika. Ma cellulose ethers amaonetsetsa kuti matailosi sakutsetsereka akagwiritsidwa ntchito ndipo amapereka nthawi yokwanira yosinthira.
3.3. Mtondo Wodziyimira Payokha
Kuchuluka kwa madzi ndi kukhazikika ndikofunikira. Sankhani ether ya cellulose yokhala ndi kukhuthala kochepa komanso kusunga madzi ambiri kuti mupewe kutuluka magazi ndi kulekanitsa.
3.4. Chotengera cha Kuteteza Kunja (EIFS)
Kusunga madzi kumakhudza mwachindunji kugwirizana pakati pa bolodi lotetezera kutentha ndi matope. Ma cellulose ether amatha kuonetsetsa kuti zinthu zikuyenda bwino nthawi zonse akagwiritsidwa ntchito kwambiri.
4. Zofunika Kuganizira Zosankha ndi Kuwonjezera
Kusankha Kukhuthala: Kukhuthala kwakukulu kumapereka madzi okwanira koma kumachepetsa kugwira ntchito; kukhuthala kochepa kumapereka madzi okwanira koma kumayambitsa kutuluka magazi. Kusintha kuyenera kupangidwa kutengera kapangidwe kake. Kuchuluka kowonjezera: Kawirikawiri 0.1% mpaka 0.5% ya kulemera kwa zinthu zomangira simenti. Kuwonjezera kwambiri kungakhudze mphamvu ndi nthawi youma.
Kufalikira: Kufalikira bwino kumafunika panthawi yosakaniza youma kuti madzi asapangike.
Kukonza magwiridwe antchito a matope osakaniza ndi madzi kumafuna njira yowonjezera yomveka bwino, komansoether ya cellulosendi chosinthira chachikulu mkati mwa dongosololi. Sikuti chimangotsimikizira kuti matope amadzi amasungidwa bwino komanso kuti agwire ntchito bwino, komanso chimakhudza mphamvu ya ma bond, kulimba, komanso ubwino wa pamwamba. Ndi kuwonjezeka kwa zofunikira pakupanga komanso kugwiritsa ntchito mfundo zopulumutsa mphamvu komanso zachilengedwe, kugwiritsa ntchito cellulose ether mu matope osakaniza ndi madzi kudzakhala kosiyanasiyana komanso kokonzedwa bwino.
