Kodi kugwiritsa ntchito ufa wobwezeretsedwanso motani?

Kubwezeretsedwanso polima (RDP) ndi njira yofunika yowonjezera, makamaka matope owuma, owuma, kusinthasintha kwa khomo la zinthu, ndipo amagwiritsidwa ntchito kwambiri m'mabuku omanga amakono.

1. Kusankha zakuthupi

Musanagwiritse ntchito ufa wobwezeretsedwa polima, muyenera kusankha mitundu yosiyanasiyana. Sankhani mitundu yosiyanasiyana ya ufa wa latex malinga ndi zosowa zenizeni za zomangamanga. Mwachitsanzo:

Polyethylene vinyl acetate Copsolmer (Eva): Kugwiritsidwa ntchito kwambiri ku Tile zomata, matope a pulasitiki, etc., ndikutsatira bwino.

Ethylene-acrylic acid CAPAlymer (VAE): Nthawi zambiri amagwiritsidwa ntchito pompopompo matope ndi kutchinga kuti muthe kuthana ndi kukana.

Acrylic Coptolymer: Kugwiritsidwa ntchito mu mphamvu zambiri, monga khoma lakunja kwa matope, ndi madzi abwino kwambiri komanso kukana nyengo.

2. Formula

Mukamagwiritsa ntchito ufa wobwezeretsedwanso, mawonekedwe amafunika kusinthidwa mogwirizana ndi zofunikira za polojekiti. Nthawi zambiri, kuchuluka kwa ufa wa latex wowonjezeredwa kuli pakati pa 2% ndi 5% ya kulemera konse kwa simenti, kutengera zofunikira zamalonda. Malingaliro ake ali motere:

Kukonzekera kusakaniza ndi simenti, kuphatikizira kwabwino (monga quartz mchenga), monga ma calcium (monga ma calcium iwr) ndi ena owuma molingana ndi gawo la formula malinga ndi kuchuluka kwa njira.

Kuphatikiza ufa wokwezeka polima: kuwaza ufa wa Matex yemwe amakhala mu ufa wosakanizika, ndikupitilizabe kuonetsetsa kuti ufa wa latx ndi ufa wina wouma umasakanizidwa bwino.

Kuonjezera ethersese ether: kuti athandize kukonza madzi osungira ndi matope a matope, kuchuluka kwa ethelose (monga hydroxypropyl) nthawi zambiri amawonjezeredwa ku folylcellulose.

3. Kukonzekera zomangamanga

Tisanamangire, onetsetsani kuti zida zonse zowinduka ndi zida zili zokonzeka, ndikusakaniza ufa wowuma molingana ndi njira. Pulogalamu yomanga, ufa wokwezedwa umabwezedwanso atalumikizana ndi filimu yokhazikika ya polimer, motero imalimbikitsa chotsatsa ndi kukana madzi kwa matope.

Kusakaniza: Onjezani madzi oyenera kwa owuma ufa, ndikusuntha mogwirizana ndi makina osokoneza bongo mpaka yunifolomu, kumasula kwaulere, kumasula kwaulere kumapangidwa. Nthawi yosangalatsa nthawi zambiri imakhala mphindi 3-5 kuonetsetsa kuti ufa wonse umanyowa kwathunthu.

Kuyimirira ndi kusanthula: Mukatha kusungulumwa, kusalala kuyenera kusiyidwa kwa mphindi zochepa kuti akhwime kwathunthu kukonza zomanga. Kenako panganinso pang'ono musanagwiritse ntchito.

4. Njira Yogwiritsira Ntchito

Ikani ma slorry osakanikirana kupita kumalo omanga malinga ndi zofunikira za ntchito yomanga. Njira zogwiritsira ntchito zofanana ndi izi:

Kupaka matope: Gwiritsani ntchito spraper kapena troweli kuti mugwiritse ntchito matopewo ku khoma, yomwe ili yoyenera kukhoma la mkati ndi chakunja.

Tile yomatira: Gwiritsani ntchito spraper yolowera kuyika tile zomatira pansi, kenako ndikukanikizani pamasamba omatira.

Matope okhathamira: kutsanulira matope osakanikirana pansi ndikugwiritsa ntchito malo ake odzipangitsa kuti apange malo osanjikiza.

5. Kusamala

Mukamagwiritsa ntchito ufa wobwezeretsedwa polima, samalani ndi mfundo zotsatirazi:

Zochitika Zachilengedwe: Malo omanga amayenera kukhala kutentha ndi chinyezi kuti mupewe kuchuluka kwa kutentha kwambiri kapena kutentha kwambiri pa matope. Kutentha kwakukulu kumayenera kukhala pakati pa 5°C ndi 35°C.

Kusakaniza madzi: Gwiritsani ntchito madzi oyera, osakanikirana osakanikirana kupewa mavuto amtundu wamadzi omwe akukhudza matope.

Ufa wosagwiritsidwa ntchito ufa uyenera kusungidwa m'malo owuma, ozizira kuti asatenthe kutentha komanso kutentha kwambiri.

Kukonzekera Kutengera: Malinga ndi vuto lenileni, sinthani mosasintha kuchuluka kwa ufa wowonjezeredwa wowonjezeredwa kuti mukwaniritse zabwino kwambiri.

6. Kuyesa kwa magwiridwe antchito ndi kukonza

Ntchito yomanga itamalizidwa, matope omalizidwa ayesedwe kugwira ntchito, monga kulimbikira, mphamvu zochulukitsa, madzi kukana, ndi zina zotere. Nthawi yomweyo, malo omwe ntchito yomanga iyenera kusamalidwa, makamaka kutentha kwambiri kapena malo owuma, kupewa kutaya madzi oyambira kumadzi ndi matope.

Monga chowonjezera chowonjezera, chosinthidwa polima polima chimatenga gawo lofunikira pakusintha zomatira, kusinthasintha ndi kukhazikika kwa matope. Kusankha koyenera ndikugwiritsa ntchito ufa wa polimaso sikungathetse bwino zomangamanga, komanso kwezani moyo wa nyumbayo. Mwa ntchito yeniyeni, ogwira ntchito omanga ayenera kutsatira mawonekedwe ndi zofuna zomanga kuti zitsimikizire kukhazikika ndi kudalirika kwa ukadaulo wapamwamba.
