Redispersible latex powder (RDP)ndi zinthu za polima zomwe zimagwiritsidwa ntchito kwambiri pantchito yomanga, zomwe zimagwiritsidwa ntchito ngati chowonjezera cha putty, zokutira, zomatira ndi zinthu zina. Ntchito yake yayikulu ndikuwongolera kusinthasintha, kumamatira, kukana madzi ndi anti-kukalamba katundu.
1. Sinthani kumamatira kwa putty
Kuphatikizika kwa ufa wa latex wopangidwanso ku putty kumatha kupititsa patsogolo kumamatira pakati pa putty ndi pansi (monga simenti, gypsum board, etc.). Ufa wa latex ukasungunuka m'madzi, umapanga chinthu cha colloidal, chomwe chingakhazikitse mphamvu yolumikizirana yakuthupi ndi mankhwala pakati pa putty ndi pansi. Kumamatira kowonjezera kumatha kusintha kwambiri kapangidwe ka putty, kupewa kusweka, kukhetsa ndi zovuta zina, ndikukulitsa moyo wautumiki wa putty.
2. Sinthani kusinthasintha ndi kukana kwa ming'alu ya putty
Kusinthasintha kwa putty ndichinthu chofunikira kwambiri chomwe chimakhudza kulimba kwake komanso ntchito yomanga. Redispersible latex ufa umathandizira kukulitsa kukhazikika komanso kusinthasintha mu putty. Chifukwa cha mphamvu ya mamolekyu a ufa wa latex, putty amatha kupeza kusungunuka pambuyo poyanika, ndipo amatha kusinthasintha pang'ono pamunsi, potero kuchepetsa ming'alu yomwe imayambitsidwa ndi zinthu monga kusintha kwa kutentha ndi kusinthasintha kwa chinyezi. Izi ndizofunikira kwambiri pakukongola ndi kukhazikika kwa zokongoletsera zapakhoma.
3. Sinthani kukana kwamadzi ndi kukana kwanyengo kwa putty
Latex ufa ukhoza kupititsa patsogolo kukana kwamadzi kwa putty mwa kukonza hydrophobicity ya putty. Traditional putty imayamwa madzi mosavuta ndikufufuma pamalo a chinyezi, zomwe zimapangitsa kuti putty layer isungunuke ndikuwumba. Mukawonjezera ufa wa latex wopangidwanso, mphamvu yoyamwa madzi ya putty imachepetsedwa kwambiri, ndipo imatha kukana kukokoloka kwamadzi. Kuphatikiza apo, kuwonjezera kwa ufa wa latex kumathandizanso kukana kwa nyengo kwa putty, kotero kuti putty amatha kukhalabe ndi magwiridwe antchito atatha nthawi yayitali kumadera ovuta monga mphepo, mvula ndi dzuwa.
4. Kupititsa patsogolo ntchito yomanga ya putty
Redispersible latex ufa ukhoza kupititsa patsogolo ntchito yomanga ya putty. Kuphatikiza kwa ufa wa latex kumapangitsa kuti putty ikhale yosavuta kugwiritsa ntchito ndikugwira ntchito, kuchepetsa zovuta komanso kulimba kwa ntchito yomanga. The fluidity ndi operability wa putty adzakhala bwino, ndipo flatness ndi kumatira kwa wokutira akhoza patsogolo patsogolo. Ufa wa latex umapangitsa kuti putty azikhala ndi zinthu zina zochiritsa pang'onopang'ono panthawi yowumitsa, kupewa ming'alu kapena zokutira zosagwirizana zomwe zimachitika chifukwa cha kuyanika mwachangu kwa putty pakumanga.
5. Sinthani kukana kwa chisanu kwa putty
M'madera ozizira, putty ikhoza kutaya ntchito yake yoyambirira chifukwa cha kutentha kochepa, komanso kuyambitsa mavuto monga kusweka ndi kugwa. Kuwonjezera kwa redispersible latex ufa kumatha kusintha kwambiri kukana kwa chisanu kwa putty. Latex ufa ukhoza kukhalabe wokhazikika pamawonekedwe otsika komanso kupewa zovuta za putty chifukwa cha kuzizira. Choncho, kugwiritsa ntchito putty yokhala ndi latex ufa m'madera ozizira monga kumpoto kungathandize kwambiri kukhazikika ndi kudalirika kwa mankhwalawa.
6. Chepetsani porosity ndikuwonjezera kachulukidwe ka putty
Kuphatikizika kwa latex ufa kumatha kuchepetsa porosity ya putty ndikuwonjezera kuchuluka kwa putty. Panthawi yopanga filimu ya putty, ufa wa latex ukhoza kudzaza tinthu ting'onoting'ono tating'onoting'ono mkati mwa putty, kuchepetsa kulowa kwa mpweya ndi madzi, ndikupititsa patsogolo kukana kwa madzi, kukana kuipitsidwa ndi mphamvu ya putty. Kuphatikizika kwa putty kumakhudza kwambiri kulimba kwa khoma lonse, ndipo kumatha kuwongolera bwino khoma pambuyo pakugwiritsa ntchito nthawi yayitali.
7. Sinthani katundu wotsutsana ndi kuipitsa wa putty
Putty layer ndiye maziko a utoto. Kuwonekera kwa nthawi yaitali ku fumbi, mafuta, acidic ndi alkaline zinthu mumlengalenga ndi zina zowononga zowonongeka zidzakhudza zotsatira zomaliza za utoto. Redispersible latex ufa umathandizira kuchepetsa mphamvu ya adsorption ya putty pamwamba, potero kuchepetsa kumamatira kwa zowononga. Izi sizimangowonjezera kukhazikika kwa putty, komanso zimasunga kukongola kwa utoto wa khoma.
8. Wonjezerani makulidwe omanga a putty
Popeza ufa wa latex ukhoza kupititsa patsogolo mgwirizano ndi madzi a putty, putty pogwiritsa ntchito latex ufa nthawi zambiri amatha kuthandizira makulidwe akulu omanga. Mbali imeneyi ndi yofunika kwambiri kwa makoma ena omwe amafunikira makulidwe akuluakulu kuti akonze, zomwe zingathe kuonetsetsa kuti khoma lokonzedwanso limakhala losalala komanso lopanda ming'alu pakagwiritsidwe ntchito nthawi yayitali.
Chikoka charedispersible latex ufaPa putty imakhala ndi zinthu zambiri, zomwe zimawonetsedwa makamaka pakuwongolera kumamatira, kusinthasintha, kukana madzi, kukana chisanu, ntchito yomanga komanso kutsutsa kuipitsidwa kwa putty. Monga chosinthira chabwino kwambiri, ufa wa latex sungowonjezera mtundu wa putty ndikuwonjezera kulimba kwake, komanso umapangitsa kuti putty azitha kusinthika m'malo osiyanasiyana omanga. Pamene zofunikira zamakampani omanga pakumanga makoma zikuwonjezeka, kugwiritsa ntchito ufa wa latex wopangidwanso kudzachulukirachulukira, ndipo zotsatira zake pa zinthu za putty zidzakhala zofunikira kwambiri.
