Kuyika miyala ndi chinthu chapadera chomwe chimagwiritsidwa ntchito kudzaza mipata ya miyala, kukonza zokongoletsera komanso kukhazikika kwa kapangidwe kake, ndipo chimafuna kumamatira bwino, kukana ming'alu, kukana nyengo komanso kukana madzi.Ufa wa polima wosungunukanso (RDP)ndi gawo lofunika kwambiri losinthidwa mu njira yopangira miyala ya grouting, yomwe ingathandize kwambiri kuti zinthu zopangira grouting zigwire bwino ntchito, zomwe zimapangitsa kuti zikhale zolimba komanso zogwira ntchito bwino pa ntchito zamkati ndi zakunja.
1. Makhalidwe oyambira ndi njira yogwirira ntchito ya RDP
RDP ndi ufa wa polima wotha kusungunuka womwe umakonzedwa pogwiritsa ntchito njira yopopera. Zinthu zoyambira zomwe zimagwiritsidwa ntchito ndi monga ethylene-vinyl acetate (EVA), acrylate copolymer ndi styrene-acrylate copolymer. RDP ikhoza kusungunukanso kuti ipange emulsion ya polima ikakumana ndi madzi, ndikupanga filimu ya polima ya netiweki yokhala ndi zinthu zothira madzi a simenti kapena zodzaza kuti iwonjezere kusinthasintha ndi mphamvu yonse yolumikizirana ya grouting. Mu grouting ya miyala, filimu ya polima iyi imatha kupanga "mlatho womatira" pamwamba pa mwalawo, kukana bwino kupsinjika komwe kumachitika chifukwa cha kutentha ndi kupindika, ndikuchepetsa chiopsezo cha kusweka.
2. Kulimbitsa kukanikiza ndi kukana ming'alu
Kuyika miyala m'makoma nthawi zambiri kumagwiritsidwa ntchito kudzaza mipata mu miyala yachilengedwe, marble, granite ndi zinthu zina. Makoma awa ali ndi malo okhuthala komanso madzi ochepa, ndipo amakhala ndi zomatira zochepa ku matope wamba a simenti. Pambuyo powonjezera RDP, filimu yosinthasintha ya polima yomwe imapangidwa mu grouting imapangitsa kuti kumamatira ku miyala kukhale kolimba, ndipo imatha kusunga mgwirizano wabwino ngakhale pamalo omwe kutentha kwake kuli kosiyana kwambiri, kuteteza ming'alu ndi kugwa. Nthawi yomweyo, RDP imapatsa grouting zinthuzo mphamvu zinazake, zomwe zingathandize kuchepetsa ming'alu yomwe imabwera chifukwa cha kuchepa kapena mphamvu zakunja pa malo olumikizira miyala.
3. Kulimbitsa kukana madzi ndi kusalowa madzi
Zipangizo zopangira miyala zimayera, kusweka kapena kugwa zikaikidwa pamalo ozizira kwa nthawi yayitali. Filimu yolimba ya polymer yopangidwa ndi RDP mu dongosolo la grouting imatha kuchepetsa ma capillary pores, kukonza kusalowa kwa zinthuzo komanso kukana madzi, motero imaletsa chinyezi kulowa mkati mwa mwalawo. Izi ndizofunikira kwambiri pa grouting ya miyala m'malo onyowa kapena owonekera monga zimbudzi, makhitchini ndi malo akunja.
4. Kuwongolera magwiridwe antchito a zomangamanga
Kuyambitsa RDP sikuti kumangowonjezera mphamvu za makina a grouting yomalizidwa, komanso kumawonjezera luso lake lomanga. RDP imatha kukonza kusunga madzi mu slurry ndikuletsa ming'alu yocheperako yomwe imachitika chifukwa cha kutayika kwa madzi koyambirira; nthawi yomweyo, imapangitsa kuti grouting ikhale yosavuta kudzaza ming'alu yaying'ono ndikupanga malo osalala komanso athyathyathya. Malo otayirira pambuyo pomanga ndi osavuta kuyeretsa, kuchepetsa chiopsezo choipitsa pamwamba pa miyala.
5. Kulimbitsa kukana kwa nyengo ndi kukongola
Pakupukuta miyala panja, kukana kukalamba kwa UV ndi kukana kuzizira ndi zizindikiro zofunika kwambiri poyesa magwiridwe antchito kwa nthawi yayitali. RDP imapatsa zinthu zopangira utoto utoto kukana nyengo yabwino kwambiri ndipo imatha kusunga kapangidwe kokhazikika pansi pa kutentha kwambiri komanso kotsika komanso kouma. Kuphatikiza apo, kusinthasintha kwakukulu kwa RDP kumatha kuchepetsa kusiyana kwa mitundu kapena kupotoka komwe kumachitika chifukwa cha kupsinjika kwa chilengedwe ndikuwonjezera kukongola kwa pamwamba pa miyala.
6. Mlingo wa RDP ndi kukonza bwino njira yopangira mankhwala
Kuchuluka kwa RDP mu zinthu zopangira miyala kuyenera kutsimikiziridwa malinga ndi zinthu monga mtundu wa substrate, m'lifupi mwa msoko, ndi malo omangira, ndipo nthawi zambiri ndi 2% mpaka 6% ya kulemera kwa zinthu zopangira simenti. Mlingo wokwera kwambiri ungayambitse kuchepa kwakukulu ndi ndalama zambiri, pomwe mlingo wochepa kwambiri sungakwaniritse magwiridwe antchito omwe amayembekezeredwa. Chifukwa chake, popanga zenizeni, ndikofunikira kukonza bwino njirayo kudzera mu zoyeserera ndikuyisintha pamodzi ndi zowonjezera zina monga cellulose ether, defoamer ndi filler kuti mupeze kapangidwe kabwino kwambiri ndi kugwiritsa ntchito.
Monga gawo lofunikira losinthidwa la mayankho a miyala grouting,RDP ikhoza kukonza bwino kumatirira, kusinthasintha, kukana madzi komanso kukana nyengo kwa zinthu zopangira grouting., ndipo imakweza kwambiri magwiridwe antchito omanga ndi mtundu wa chinthu chomalizidwa. Kugwiritsa ntchito kwake mu miyala yachilengedwe, marble ndi granite kungathandize kukulitsa moyo wa polojekitiyi ndikusunga kukongola kwa miyala. M'tsogolomu, ndi chitukuko cha RDP yogwira ntchito bwino komanso yosawononga chilengedwe, njira zothetsera miyala zomangira zidzasinthidwa kukhala zolimba kwambiri, zocheperako komanso zokhalitsa kwa nthawi yayitali.
