Makina opopera a polyurethane/polyureawopanga, zida ndi oyenera kutchinjiriza matenthedwe, madzi, odana ndi dzimbiri, kuthira, etc.
Kupopera mbewu kwa polyurethane kuyenera kuchitika m'malo ambiri.Zikuoneka kuti anthu ambiri awona ntchito yomanga kupopera mankhwala a polyurethane, koma sadziwa konse za zomangamanga za kupopera mankhwala a polyurethane, ndipo sakudziwa kuti ntchitoyo ndi yotani.Lero ndikuwonetsani nonse Fotokozani njira yopangira kupopera mbewu kwa polyurethane.

1. Basic mawonekedwe processing
Khoma loyambira liyenera kukwaniritsa zofunikira, kusalala kwa khoma kuyenera kukhala 5-8mm, ndipo mayendedwe akuyenera kukhala mkati mwa 10mm.
A: Khoma liyenera kutsukidwa kuti liwonetsetse kuti khoma lilibe laitance, mafuta odzola, fumbi, ndi zina zotero.
B: Chowonongeka pakhoma chakonzedwa ndi matope a simenti.
C: Pamene khomalo likukulirakulira kapena lofanana ndi 10mm, liyenera kuchotsedwa.
D: Mapaipi okwiriridwa, mabokosi a waya ndi magawo ophatikizidwa pakhoma ayenera kukhazikitsidwa pasadakhale, ndipo chikoka cha makulidwe a wosanjikiza wotsekera chiyenera kuganiziridwa.
E: Musanayambe kupopera thovu lolimba la polyurethane, gwiritsani ntchito filimu ya pulasitiki, nyuzipepala ya zinyalala, bolodi la pulasitiki kapena bolodi lamatabwa, plywood kuphimba ndi kuteteza mazenera, zitseko ndi zipangizo zina zosaphimba.Chitseko cha denga ndi chimango cha zenera ziyenera kupopera thovu lolimba la polyurethane musanayike kuti zisawonongeke.

2. Kupachika chopingasa ndi zotanuka kulamulira mzere
Maboti okulitsa amayikidwa pansi pa khoma lapamwamba ndi khoma lapansi ngati popachikidwa pakhoma lalikulu lolendewera waya.Theodolite imagwiritsidwa ntchito poyika waya wolendewera wa ma skyscrapers, ndipo waya wawukulu umagwiritsidwa ntchito pomanga nyumba zokhala ndi nsanjika zambiri kupachika waya wopyapyala wolendewera, ndikumangitsa ndi cholumikizira waya.Ikani mizere yowongoka yachitsulo pamakona akulu a yin ndi yang a khoma, ndipo mtunda wapakati pa mizere yowongoka yachitsulo ndi khoma ndi makulidwe onse a wosanjikiza wamafuta.Pambuyo popachika mzerewo, choyamba yang'anani kutsetsereka kwa khoma ndi wolamulira wa 2m bar pamtunda uliwonse, ndipo yang'anani kutalika kwa khoma ndi bolodi yothandizira 2m.Ntchitoyi ikhoza kuchitika pokhapokha ngati zofunikira za flatness zakwaniritsidwa.

3. Kupopera mbewu mankhwalawa olimba thovu polyurethane
Yatsani makina opoperapo mankhwala a polyurethane kuti mupoperani chithovu cholimba cha polyurethane pakhoma.
Yankho: Kupopera mbewu mankhwalawa kuyenera kuyambira m'mphepete, mutatha kuchita thovu, tsitsani m'mphepete mwa thovu.
B: Makulidwe a kutsitsi koyamba kuyenera kuyendetsedwa pafupifupi 10mm.
C: Makulidwe a chiphaso chachiwiri chiyenera kuyendetsedwa mkati mwa 15mm mpaka makulidwe ofunikira ndi kapangidwe kake.
D: Pambuyo popopera utoto wonyezimira wa polyurethane wosanjikiza, makulidwe a wosanjikizawo ayenera kuyang'aniridwa momwe amafunikira, ndipo kuwunika kwaubwino kuyenera kuchitidwa molingana ndi zofunikira za gulu loyang'anira zolemba zowunikira.
E: Pambuyo popopera mankhwala otsekemera a polyurethane kwa mphindi 20, gwiritsani ntchito pulani, chocheka chamanja ndi zida zina kuti muyambe kuyeretsa, chepetsani mthunzi, tetezani zigawo ndi zotuluka zomwe zimadutsa makulidwe otchulidwa ndi 1cm.

4. Kupenta mawonekedwe matope
The polyurethane mawonekedwe matope mankhwala ikuchitika 4 maola wosanjikiza m'munsi polyurethane kupopera, ndi mawonekedwe matope akhoza wogawana TACHIMATA pa polyurethane kutchinjiriza m'munsi wosanjikiza ndi wodzigudubuza.Pofuna kulimbikitsa kuphatikizika pakati pa nsonga yotchinga ndi yosalala, kupewa kusweka ndi kugwa, komanso kuteteza wosanjikiza wa polyurethane kuti asawonekere ndi kuwala kwa dzuwa ndikupangitsa chikasu ndi choko.Pambuyo kupopera mbewu mankhwalawa polyurethane mawonekedwe matope kwa maola 12-24, ntchito yomanga ndondomeko yotsatira ikuchitika.Dziwani kuti matope opangidwa ndi polyurethane sangathe kupopera masiku amvula.

5. Ntchito yomanga matope osanjikiza ndi kumaliza wosanjikiza
(1) Kupaka utoto
① Ikani matope osamva ming'alu ndi kuyala pansi mauna osamva alkali.Mauna osamva alkali ndi pafupifupi 3m kutalika, ndipo kukula kwake kumadulidwatu.Mtondo wotsutsana ndi ming'alu nthawi zambiri umamaliza m'magawo awiri, ndi makulidwe okwana pafupifupi 3mm mpaka 5mm.Mukangopukuta matope osamva ming'alu ndi malo ofanana ndi nsalu ya mesh, kanizani nsalu yosagwirizana ndi alkali ndi chitsulo.M'lifupi mwake pakati pa nsalu za mesh zosagwira alkali siziyenera kuchepera 50mm.Nthawi yomweyo kanikizani nsalu ya mauna osamva alkali yokhala ndi chitsulo chachitsulo motsatana kuchokera kumanzere kupita kumanja komanso kuchokera pamwamba mpaka pansi, ndipo kuphatikizika kowuma ndikoletsedwa.Makona a yin ndi yang akuyeneranso kupitirana, ndipo m'lifupi mwake ayenera kukhala ≥150mm, ndipo makulidwe ndi kutsika kwa ngodya za yin ndi yang ziyenera kutsimikiziridwa.Nsalu ya mesh yosamva alkali iyenera kukhala mumtondo woletsa kung'ambika, ndikuyikapo kuyenera kukhala kosalala komanso kopanda makwinya.Ma mesh amatha kuwoneka bwino, ndipo matopewo ndi odzaza.Magawo omwe sali odzaza ayenera kudzazidwa nthawi yomweyo ndi matope odana ndi ming'alu kachiwiri kuti afikire komanso osakanikirana.
Ntchito yomanga matope odana ndi ming'alu ikamalizidwa, yang'anani kusalala, kukhazikika ndi masikweya a ngodya za yin ndi yang, ndipo gwiritsani ntchito matope odana ndi ming'alu kuti mukonze ngati sizikukwaniritsa zofunikira.Ndi zoletsedwa kugwiritsa ntchito waistline matope wamba simenti, zenera manja, etc. pamwamba.
②Pala chopunthira chosagwira madzi ndikuyika utoto womaliza.Pambuyo pakuwuma kwa anti-cracking, pukutani putty yosagwira madzi (yopambana nthawi zambiri, makulidwe a scraping aliwonse amayendetsedwa pafupifupi 0.5mm), ndipo kumaliza kumafunika kukhala kosalala komanso koyera.
(2) Kumaliza njerwa
① Ikani matope osamva ming'alu ndikuyala mawaya otenthetsera ovimbitsidwa ndi malata.
Pambuyo pakuwunikira ndikuvomerezedwa, matope oletsa kukwapula amagwiritsidwa ntchito, ndipo makulidwe ake amayendetsedwa pa 2mm mpaka 3mm.Dulani otentha-kuviika kanasonkhezereka welded waya mauna malinga structural kukula, ndi kuyala izo mu zigawo.Kutalika kwa kutentha-kuviika kanasonkhezereka welded waya mauna sayenera upambana 3m.Pofuna kuonetsetsa kuti m'makona amamanga bwino, chingwe cha waya chotenthetsera chotenthetsera chotenthetsera pamakona amapindika molunjika musanayambe kumanga.Podula mauna, ma mesh sayenera kupindika kukhala makutu akufa, ndipo thumba la mesh lisamapangidwe panthawi yoyika.Ukonde ukatsegulidwa, uyenera kuyikidwa pansi motsatira njira.Zinki welded waya mauna kuti kuyandikira pamwamba pa odana ndi ming'alu matope, ndiyeno nangula otentha-kuviika kanasonkhezereka welded waya mauna pa m'munsi khoma ndi mabawuti kukulitsa nayiloni.Yatsani kusalinganika ndi kopanira ngati U.M'lifupi mwake m'lifupi pakati pa ma meshes owotcherera otenthetsera otentha sikuyenera kukhala osachepera 50mm, kuchuluka kwa zigawo zophatikizika sikuyenera kupitilira 3, ndipo zolumikizira zingwe ziyenera kukhazikika ndi tatifupi zooneka ngati U, mawaya achitsulo kapena mabawuti a nangula.Misomali ya simenti ndi ma gaskets ayenera kugwiritsidwa ntchito kumapeto kwa kutentha-kuviika kanasonkhezereka waya mauna mkati mwa zenera, khoma khoma, kukhazikikamo olowa, etc., kuti otentha-kuviika kanasonkhezereka welded waya mauna akhoza anakhazikika pa. dongosolo lalikulu.
Pambuyo poyatsidwa ndi waya wotenthetsera wotenthetsera wotenthetsera ndikuwunikiridwa, matope odana ndi ming'alu adzagwiritsidwa ntchito kachiwiri, ndipo mauna otenthetsera otenthetsera waya amakutidwa ndi matope odana ndi ming'alu.Chosanjikiza chophwanyika chamatope chiyenera kukwaniritsa zofunikira za flatness ndi verticality.
②Matale a veneer.
Ntchito yomanga matope odana ndi ming'alu ikamalizidwa, iyenera kupopera bwino ndikuchiritsidwa, ndipo phala la matope a veneer litha kuchitika pakadutsa masiku 7.Makulidwe a matope omangira njerwa ayenera kuwongoleredwa mkati mwa 3mm mpaka 5mm.
