Redispersible polima ufa si poizoni komanso wokonda chilengedwe. Ndizowonjezera zofunika kwa zipangizo zatsopano zomangira. Kuthira ufa wa polima wotayikanso mumatope kumasintha kaphatikizidwe ka pore, kumachepetsa kachulukidwe ka matope, kumawonjezera kulumikizana kwamkati kwa matope, komanso kumathandizira kuyamwa kwamadzi mumatope. ; Kuwonjezera ufa wa polima wotayikanso mumatope kumawonjezera kukana kwa matope; Kugwirizana kwabwino kwa ufa wa polima wopangidwanso kumapangitsa kuti matope akhalenso ndi mgwirizano wabwino, makamaka matope omangira. , kuwongolera kwambiri magwiridwe antchito a matope; kugwiritsa ntchito ufa wa polima kuti musinthe matope a simenti kumatha kupanga matope owuma okhala ndi ntchito zosiyanasiyana, kupereka chiyembekezo chamsika chochulukirapo pakugulitsa matope. Ikhoza kupanga mikhalidwe yabwino yogwiritsira ntchito matekinoloje atsopano ndi zipangizo, kugwiritsa ntchito kuwongolera khalidwe labwino, kuwongolera njira zomangira, ndikuwonetsetsa kuti ntchitoyo ndi yabwino.
Udindo wa ufa wa polima wopangidwanso mumatope:
1 Limbikitsani mphamvu yopondereza komanso mphamvu yosunthika yamatope.
2 Kuphatikizika kwa ufa wa polima kumawonjezera kutalika kwa matope, motero kumapangitsa kulimba kwa matope, komanso kumapangitsa kuti matopewo akhale ndi zotsatira zabwino zobalalika.
3 Kupititsa patsogolo mgwirizano wamatope. Njira yolumikizirana imatengera kutengera ndi kufalikira kwa ma macromolecules pamtunda womata. Panthawi imodzimodziyo, ufa wa polima uli ndi mphamvu zinazake ndipo umalowa bwino pamwamba pa zinthu zoyambira ndi cellulose ether, kotero kuti zinthu zapansi pamunsi ndi pulasitala yatsopano zili pafupi, potero kuwongolera Adsorption kumawonjezera ntchito yake.
4 Chepetsani zotanuka modulus matope, kusintha luso mapindikidwe ndi kuchepetsa kusweka chodabwitsa.
5 Limbikitsani kulimba kwa matope. Kusintha kwa kukana kuvala kumakhala makamaka chifukwa cha kukhalapo kwa guluu wambiri pamwamba pa matope. Guluu ufa umakhala ngati chomangira, ndipo mawonekedwe a omentum opangidwa ndi guluu ufa amatha kudutsa mabowo ndi ming'alu ya matope a simenti. Imapititsa patsogolo mgwirizano pakati pa zinthu zoyambira ndi zinthu za simenti za hydration, potero zimawonjezera kukana.
6 Perekani matope kuti musamavutike kwambiri ndi alkali
Utoto wa polima ufa uli ndi fungo lamphamvu, silokonda zachilengedwe, ndipo ndi wotsika mtengo, koma kukana kwake kumayamwa madzi, mphamvu, ndi zina mwachiwonekere ndizotsika poyerekeza ndi ufa wopangidwanso wa polima. Choncho, pambuyo kuyerekezera mwatsatanetsatane, redispersible polima ufa ndi oyenera ntchito mu matope.
