Kukulitsa Mphamvu Yomatira: Momwe Ufa Wothiranso Polima (RDP) Umasinthira Zinthu Zomangira Ma Bonding Mortars

Chifukwa Chake Mphamvu Yogwirizana Ndi Yofunika Mu Ma Mortar Ogwirizana

Kumatira ndiye maziko a matope omangira bwino. Kaya kumamatira matailosi, kukonza konkire, kapena kukhazikitsa makina otetezera kutentha, matope ayenera:

• Pewani kupsinjika kwa kumeta ndi kupsinjikakuchokera ku kusintha kwa chilengedwe kapena katundu wa makina.
• Sungani mgwirizano wa nthawi yayitalingakhale kuti pali chinyezi, kusintha kwa kutentha, kapena kugwedezeka.
• Pewani kudulidwa kwa chigawopakati pa zinthu zomangira (monga konkriti, matabwa, kapena gypsum).

Ma matope achikhalidwe okhala ndi simenti nthawi zambiri samakhala osinthasintha komanso ogwirizana pansi pa mikhalidwe yosinthasintha. Apa ndi pomwe RDP imalowererapo ngati chowonjezera magwiridwe antchito.

Momwe RDP Imathandizira Kumamatira mu Mortars

Ufa wa Redispersible Polymer ndi copolymer youma ndi spray (monga vinyl acetate-ethylene) yomwe imapangidwanso ikasakanizidwa ndi madzi. Mu mortars omangirira, RDP imagwira ntchito ndi:

1. Kupanga Filimu ya PolimaPamene matope akuchira, RDP imapanga netiweki yosinthasintha, yolowa mkati yomwe imalumikiza tinthu ta simenti ndi ma aggregates. Filimuyi imalumikiza mipata pakati pa matope ndi substrate, zomwe zimapangitsa kuti makina azigwirana bwino.
2. Kuchepetsa KufookaMosiyana ndi ma matrices olimba a simenti, RDP imawonjezera kusinthasintha, zomwe zimathandiza kuti mortars itenge mphamvu popanda kusweka.
3. Kukonza Kunyowa: RDP imawonjezera luso la matope "logwira" malo osalala kapena oboola, ngakhale m'mikhalidwe yovuta.

Ubwino Waukulu wa RDP mu Bonding Mortars

1. Mphamvu Yapamwamba ya Chigwirizano: Ma mortar osinthidwa ndi RDP amafika mpakaKumatirira mwamphamvu kawiripoyerekeza ndi zosakaniza zosasinthidwa, malinga ndi mayeso a ASTM C1583.
2. Kukana kwa Ming'alu: Filimu ya polima imachepetsa ming'alu yaying'ono yomwe imachitika chifukwa cha kuchepa kapena kufalikira kwa kutentha.
3. Kukana Madzi: RDP imachepetsa kuyamwa kwa madzi, kuteteza mgwirizano kuti usawonongeke ndi chinyezi.
4. Kusinthasintha: Imagwira ntchito bwino pa zinthu zosiyanasiyana, kuphatikizapo konkriti, zoumba, ndi ma board oteteza ku dzuwa a EPS.
5. Kugwira ntchito bwino: RDP imakulitsa kufalikira kwa matope, kuonetsetsa kuti ntchito yake ndi yofanana komanso kuchepetsa nthawi yogwira ntchito.

RDP ikugwira ntchito: Mapulogalamu enieni

• Zomatira za Matailosi: RDP imaonetsetsa kuti matailosi amakhala olimba m'malo onyowa (monga mabafa, maiwe osambira) komanso m'malo omwe anthu ambiri amadutsa.
• Machitidwe Otetezera Khoma Akunja: Zimathandizira kuti ma base coat asamamatire ku insulation panels, zomwe zimathandiza kuti makina asamagwire bwino ntchito.
• Kukonza Konkire: Kubwezeretsa mgwirizano wa kapangidwe ka nyumba mu zomangamanga zakale popanda kusokoneza.
• Mafakitale Osanja Pansi: Amapanga mgwirizano wopanda msoko pakati pa malo akale ndi atsopano.

Kugwirizana ndi Cellulose Ethers

Kwa opanga omwe amagwiritsa ntchito ma ether a cellulose (monga HPMC, MHEC), RDP imagwira ntchito ngati chowonjezera chowonjezera. Ngakhale ma ether a cellulose amapereka madzi osungira ndi kukhuthala, RDP ikuwonjezera kuti:

• Kulimbitsa kumatirapa ntchito zofunika kwambiri zoyimirira kapena zopitilira muyeso.
• Kusinthasinthakuti zigwirizane ndi kayendedwe ka substrate.
• Kulimbam'nyengo zovuta.

Kuphatikiza zowonjezera zonse ziwiri kumapanga ma mortar omwe amakwaniritsa miyezo yapamwamba kwambiri ya zomatira zopyapyala, zokongoletsa, ndi makina okonzera.
