1. Putty imagwiritsidwa ntchito ngati chinthu chokongoletsera pamwamba kuti chikutidwe ndi zokutira zomanga.
Putty ndi wosanjikiza woonda wa matope osanjikiza. Putty amapasulidwa pamwamba pa magawo okhwima (monga konkire, matope owongolera, gypsum board, etc.) Pangani utoto wakunja wapakhoma kuti ukhale wosalala komanso wosakhwima, wosavuta kuwunjikana fumbi komanso wosavuta kuyeretsa (izi ndizofunikira kwambiri kumadera omwe kuwononga kwambiri mpweya). Putty akhoza kugawidwa mu chigawo chimodzi putty (phala putty phala ndi youma ufa putty ufa) ndi awiri chigawo putty (wopangidwa ndi putty ufa ndi emulsion) molingana ndi yomalizidwa mankhwala mawonekedwe. Ndi chidwi cha anthu paukadaulo womanga wa zokutira zomanga, putty ngati chinthu chofunikira chothandizira idapangidwanso moyenerera. Opanga osiyanasiyana apakhomo apanga motsatizana ma putty okhala ndi zolinga zosiyanasiyana ndi mitundu yosiyanasiyana, monga putty putty, phala putty, mkati khoma putty Putty, kunja khoma putty, zotanuka putty, etc.
Tikayang'ana kugwiritsa ntchito zokutira zomanga zapanyumba, nthawi zambiri pamakhala zovuta monga kuchita thovu ndi kusenda, zomwe zimakhudza kwambiri chitetezo ndi kukongoletsa kwa zokutira panyumba. Pali zifukwa ziwiri zazikulu zowonongera filimu yokutira:
Chimodzi ndi khalidwe la utoto;
Chachiwiri ndikusamalidwa bwino kwa gawo lapansi.
Zochita zawonetsa kuti kupitilira 70% ya kulephera kwa zokutira kumakhudzana ndi kusagwira bwino kwa gawo lapansi. Putty kwa zokutira zomanga zakhala zikugwiritsidwa ntchito kwambiri ngati zida zopangira zopangira kuti zikutidwe. Sizingangokhala kusalala ndi kukonza pamwamba pa nyumba, komanso putty yapamwamba imatha kupititsa patsogolo chitetezo ndi kukongoletsa kwa zokutira panyumba. Kutalikitsa moyo wautumiki wa zokutira ndi chinthu chofunikira kwambiri chothandizira pakupangira zopangira zowoneka bwino, makamaka zokutira kunja kwa khoma. Gawo limodzi louma la ufa wouma lili ndi ubwino woonekeratu wa zachuma, zamakono ndi zachilengedwe pakupanga, kuyendetsa, kusungirako, kumanga ndi zina zotero.
Zindikirani: Chifukwa cha zinthu monga zopangira ndi mtengo wake, ufa wa polima wotayika umagwiritsidwa ntchito kwambiri polimbana ndi kupasuka kwa makoma akunja, komanso kumagwiritsidwa ntchito muzitsulo zapamwamba zamkati zamkati.
2. Udindo wa anti-cracking putty kwa makoma akunja
Kunja khoma putty nthawi zambiri amagwiritsa ntchito simenti monga inorganic chomangira zinthu, ndi pang'ono kashiamu phulusa akhoza kuwonjezeredwa kukwaniritsa zotsatira synergistic. Udindo wa simenti-based anti-cracking putty pamakoma akunja:
Putty wosanjikiza pamwamba amapereka maziko abwino, omwe amachepetsa kuchuluka kwa utoto ndi kuchepetsa mtengo wa polojekiti;
Putty imakhala yomatira mwamphamvu ndipo imatha kulumikizidwa bwino pakhoma lapansi;
Ili ndi kulimba kwina, imatha kuteteza bwino kukulitsa kosiyanasiyana ndi kupsinjika kwa magawo osiyanasiyana oyambira, ndipo imakhala ndi kukana kwabwino kwa ming'alu;
Putty ali ndi kukana kwanyengo yabwino, kusasunthika, kukana chinyezi komanso nthawi yayitali yautumiki;
Zokonda zachilengedwe, zopanda poizoni komanso zotetezeka;
Pambuyo pa kusinthidwa kwa zowonjezera zogwira ntchito, monga putty rabara ufa ndi zipangizo zina, kunja kwa khoma putty kungakhale ndi ubwino wotsatirawu:
Ntchito yodula mwachindunji pazomaliza zakale (penti, matailosi, mosaic, miyala ndi makoma ena osalala);
Good thixotropy, pafupifupi wangwiro yosalala pamwamba angapezeke mwa kungopaka, ndi kutayika chifukwa cha zokutira Mipikisano ntchito chifukwa cha m'munsi m'munsi pamwamba yafupika;
Ndi zotanuka, zimatha kukana ming'alu yaying'ono, ndipo zimatha kuthana ndi kuwonongeka kwa kupsinjika kwa kutentha;
Zabwino zothamangitsa madzi komanso ntchito yosalowa madzi.
3. Udindo wa ufa wa latex wopangidwanso kunja kwa khoma la putty ufa
(1) Zotsatira za ufa wa rabara wa putty pa putty wosakanikirana:
Kupititsa patsogolo magwiridwe antchito ndikuwongolera magwiridwe antchito a putty batch scraping;
kusungirako madzi owonjezera;
kuwonjezeka kwa ntchito;
Pewani kusweka msanga.
(2) Zotsatira za ufa wa rabara wa putty pa putty wowuma:
Chepetsani zotanuka modulus ya putty ndikuwonjezera kufananiza ndi gawo loyambira;
Sinthani mawonekedwe a simenti yaying'ono, onjezani kusinthasintha mutawonjezera ufa wa rabara wa putty, ndikukana kusweka;
Kupititsa patsogolo kukana kwa ufa;
Hydrophobic kapena kuchepetsa mayamwidwe amadzi a putty layer;
Wonjezerani kumamatira kwa putty ku khoma lapansi.
Chachinayi, zofunika za kunja khoma putty ntchito yomanga
Njira yopangira putty iyenera kulabadira:
1. Mphamvu zamamangidwe:
Chikoka cha mikhalidwe yomanga makamaka kutentha ndi chinyezi cha chilengedwe. M'madera otentha, wosanjikiza wapansi ayenera kupopera bwino ndi madzi, kapena kusungidwa monyowa, malingana ndi ntchito ya mankhwala enieni a putty powder. Popeza kunja kwa khoma la putty ufa nthawi zambiri amagwiritsa ntchito simenti ngati zinthu zopangira simenti, kutentha kozungulira kuyenera kukhala kosachepera madigiri 5, ndipo sikudzawumitsidwa musanawume pambuyo pomanga.
2. Kukonzekera ndi kusamala musanakolole putty:
Zimafunika kuti ntchito yaikulu yatsirizidwa, ndipo nyumba ndi denga zatsirizidwa;
Zigawo zonse zophatikizidwa, zitseko, mawindo ndi mapaipi a phulusa ayenera kuikidwa;
Pofuna kupewa kuipitsidwa ndi kuwonongeka kwa zinthu zomwe zatsirizidwa mu ndondomeko ya batch scraping, zinthu zodzitchinjiriza zenizeni ndi miyeso ziyenera kutsimikiziridwa musanayambe kukwapula kwa batch, ndipo mbali zoyenera ziyenera kuphimbidwa ndi kukulunga;
Kuyika kwa zenera kuyenera kuchitika pambuyo poti gulu la putty litang'ambika.
3. Chithandizo chapamwamba:
Pamwamba pa gawo lapansi payenera kukhala olimba, lathyathyathya, youma ndi oyera, opanda mafuta, batik ndi zinthu zina lotayirira;
Pamwamba pa pulasitala yatsopanoyo iyenera kuchiritsidwa kwa masiku 12 kuti putty ichotsedwe, ndipo wosanjikiza woyambirira sungathe kusinthidwa ndi phala la simenti;
Ngati khomalo ndi louma kwambiri lisanamangidwe, khomalo liyenera kunyowetsedwa pasadakhale.
4. Njira yogwirira ntchito:
Thirani madzi okwanira mu chidebecho, kenaka yikani ufa wouma wouma, kenaka sakanizani bwino ndi chosakanizira mpaka mutakhala phala lofanana popanda tinthu ta ufa ndi mvula;
Gwiritsani ntchito chida chokwapula cha batch pakukakula kwa batch, ndipo kukwapula kwachiwiri kumatha kuchitika pambuyo poti wosanjikiza woyamba wa batch atha kwa maola 4;
Pala wosanjikiza wa putty bwino, ndikuwongolera makulidwe ake kukhala pafupifupi 1.5mm;
Putty yopangidwa ndi simenti ikhoza kupakidwa utoto wosagwirizana ndi alkali pokhapokha kuchiritsa kwachilengedwe kumalizidwa mpaka alkalinity ndi mphamvu zikwaniritse zofunikira;
5. Zolemba:
Kuyimirira ndi kutsetsereka kwa gawo lapansi kuyenera kutsimikiziridwa musanamangidwe;
Mtondo wosakanizidwa wa putty uyenera kugwiritsidwa ntchito mkati mwa 1 ~ 2h (malingana ndi chilinganizo);
Osasakaniza matope a putty omwe adutsa nthawi yogwiritsira ntchito ndi madzi musanagwiritse ntchito;
Iyenera kupukutidwa mkati mwa 1 ~ 2d;
Pamene m'munsi pamwamba ndi calendered ndi matope simenti, Ndi bwino kugwiritsa ntchito mawonekedwe mankhwala wothandizira kapena mawonekedwe putty ndi zotanuka putty.
Mlingo waredispersible polima ufaatha kutanthauza kuchuluka kwa mlingo mu mawonekedwe a kunja khoma putty ufa. Ndibwino kuti makasitomala azichita zoyeserera zingapo zazing'ono zisanapangidwe kuti zitsimikizire mtundu wa ufa wa putty.
