Makina ochitira a Redispersible Polymer Powder (RDP) mumatope owuma

Redispersible Polima Powder (RDP)ndi chowonjezera chofunikira pamapangidwe amatope owuma, omwe amapereka maubwino angapo monga kumamatira bwino, kulumikizana, kusinthasintha, komanso kugwira ntchito. Njira yake yochitirapo kanthu imaphatikizapo magawo angapo, kuyambira kubalalitsidwa m'madzi mpaka kuyanjana ndi zigawo zina mumsanganizo wamatope. Tiyeni tifufuze mwatsatanetsatane ndondomekoyi:

Kubalalitsidwa mu Madzi:
Ma particles a RDP adapangidwa kuti azibalalitsa mwachangu komanso mofanana m'madzi chifukwa cha chikhalidwe chawo cha hydrophilic. Kuwonjezera pa madzi owuma matope kusakaniza, izi particles pathupi ndi kumwazikana, kupanga khola colloidal kuyimitsidwa. Kubalalika kumeneku kumawonetsa malo akuluakulu a polima kumalo ozungulira, kuwongolera kuyanjana kotsatira.

Kupanga Mafilimu:
Pamene madzi akupitiriza kuphatikizidwa mu matope osakaniza, particles za RDP zomwazika zimayamba kusungunuka, kupanga filimu yopitilira kuzungulira particles cementitious ndi zina. Filimuyi imakhala ngati chotchinga, kuteteza kukhudzana mwachindunji pakati pa zipangizo za simenti ndi chinyezi chakunja. Izi ndizofunikira kuti muchepetse kulowa kwa madzi, kukulitsa kukhazikika, komanso kuchepetsa chiopsezo cha efflorescence ndi kuwonongeka kwamitundu ina.

Kuphatikizana Kumamatira ndi Kugwirizana:
Kanema wa polima wopangidwa ndi RDP amagwira ntchito ngati cholumikizira, kulimbikitsa kumamatira pakati pa matope ndi magawo osiyanasiyana monga konkire, miyala, kapena matailosi. Kanemayo amathandiziranso mgwirizano mkati mwa matope amatope potseka mipata pakati pa tinthu tating'onoting'ono, motero kumawonjezera mphamvu zonse ndi kukhulupirika kwa matope owuma.

Flexibility ndi Crack Resistance:
Ubwino umodzi wofunikira wa RDP ndikutha kwake kupereka kusinthika kwa matrix amatope. Kanema wa polima amalola kusuntha kwakung'ono kwa gawo lapansi komanso kukulitsa kutentha, kuchepetsa chiopsezo chosweka. Kuonjezera apo, DPP imapangitsa kuti matope azikhala olimba komanso amphamvu, ndikupititsa patsogolo kukana kwake kuti asaphwanyike pansi pa katundu wokhazikika komanso wamphamvu.

Kusunga Madzi:
Kukhalapo kwa RDP mumsanganizo wa matope kumathandiza kuwongolera kusungidwa kwa madzi, kuteteza kutuluka kwa nthunzi mofulumira kumayambiriro kwa machiritso. Nthawi yotalikirayi ya hydration imalimbikitsa simenti yathunthu ndikuwonetsetsa kuti zinthu zikuyenda bwino pamakina, monga compressive ndi flexural mphamvu. Kuphatikiza apo, kusungidwa kwamadzi koyendetsedwa bwino kumathandizira kuti ntchito ziziyenda bwino komanso nthawi yayitali yotseguka, kumathandizira kugwiritsa ntchito mosavuta komanso kumaliza matope.

Kupititsa patsogolo Kukhalitsa:
Powongolera kumamatira, kusinthasintha, komanso kukana kusweka, DPP imathandizira kwambiri kulimba kwa ntchito zamatope owuma. Kanema wa polima amakhala ngati chotchinga chotchinga ku chinyezi, kuwonongeka kwa mankhwala, ndi zowononga chilengedwe, potero kumakulitsa moyo wautumiki wamatope ndikuchepetsa zofunikira pakukonza.

Kugwirizana ndi Zowonjezera:
RDPimawonetsa kuyanjana kwabwino kwambiri ndi zowonjezera zosiyanasiyana zomwe zimagwiritsidwa ntchito popanga matope owuma, monga zolowetsa mpweya, ma accelerator, retarders, ndi inki. Kusinthasintha kumeneku kumathandizira kusinthika kwazinthu zamatope kuti zikwaniritse zofunikira pakugwiritsa ntchito mosiyanasiyana komanso zachilengedwe.

Njira yogwiritsira ntchito ufa wa polima wotayika mumatope owuma umaphatikizapo kubalalitsidwa m'madzi, kupanga filimu, kumamatira ndi kugwirizanitsa, kusinthasintha ndi kukana ming'alu, kusunga madzi, kupititsa patsogolo kukhazikika, komanso kugwirizana ndi zowonjezera. Zotsatira zophatikizikazi zimathandizira kupititsa patsogolo magwiridwe antchito, kugwira ntchito, komanso kulimba kwa machitidwe amatope owuma pamitundu yambiri yomanga.
