Zovala za polyurea zimapangidwa makamaka ndi zigawo za isocyanate ndi ma polyether amines. Zida zamakono za polyurea makamaka zimakhala ndi MDI, polyether polyols, polyether polyamines, amine chain extenders, zowonjezera zina zogwira ntchito, pigment ndi fillers, ndi zosungunulira zogwira ntchito. Zovala za polyurea zimakhala ndi mawonekedwe a liwiro lochiritsa mwachangu, liwiro lomanga mwachangu, anti-corrosion ndi ntchito yosalowa madzi, kutentha kwakukulu, ndi njira yosavuta. Ndiwoyenera makamaka kumabizinesi osiyanasiyana amakampani ndi migodi, malo oimikapo magalimoto, mabwalo amasewera, ndi zina zambiri, zokutira pansi ndi zofunikira za anti-slip, anti-corrosion and wear resistance.

NKHANI ZA PRODUCT

Kukana kuvala kwapamwamba, kusagwirizana ndi zokanda, moyo wautali wautumiki;
Ili ndi kulimba kwabwinoko kuposa pansi pa epoxy, popanda kusenda kapena kusweka:
Kugundana kwapamtunda ndikokwera, zomwe zimapangitsa kuti zisasunthike kwambiri kuposa pansi pa epoxy.
Kupanga filimu yachijasi chimodzi, kuyanika mwachangu, kupanga kosavuta komanso kofulumira:
Kupakanso kumamatira kwambiri ndipo ndikosavuta kukonza.
Mitundu imatha kusankhidwa mwaufulu. Ndi yokongola ndi yowala. Ndiwopanda poizoni komanso wokonda zachilengedwe.

Sitima Yamasewera

1. Chithandizo choyambirira chapamwamba: Chotsani fumbi, madontho amafuta, zosungiramo mchere, dzimbiri, ndi zotulutsa kuchokera pansi posesa poyamba ndikuyeretsa. Pambuyo popera mokwanira, kusonkhanitsa fumbi la vacuum kumachitika.
2. Kugwiritsa ntchito kwapadera koyambira: Pereka gwiritsani ntchito choyambira chapadera cha polyurea kuti musindikize ma pores a capillary, kuchepetsa zowonongeka zowonongeka, ndikuwonjezera kumamatira pakati pa zokutira za polyurea ndi pansi.
3. Patching ndi polyurea putty (kutengera momwe m'munsi amavalira): Gwiritsani ntchito zida zapadera zophatikizira polyurea kukonza ndi kusanja pansi. Mukachiza, gwiritsani ntchito gudumu lopera lamagetsi kuti mupange mchenga bwino ndikutsuka ndi chotsukira.
4. Pereka gwiritsani ntchito pulayimale yapadera ya polyurea: Tsekaninso pansi, ndikuwonjezera kwambiri kumamatira pakati pa polyurea ndi maziko.
5. Utsi polyurea ❖ kuyanika madzi: Pambuyo kuyezetsa kutsitsi, utsi mu dongosolo kuchokera pamwamba mpaka pansi, kusuntha mu kadera kakang'ono mu crosswise ndi longitudinal chitsanzo. Kutalika kwa tsinde ndi 1.5-2 mm. Kupopera mbewu mankhwalawa kumatsirizidwa kamodzi. Njira zenizeni zitha kupezeka mu "Polyurea Engineering Coating Specifications". Imagwira ntchito yofunika kwambiri poletsa madzi, imakhala yosavala komanso yosasunthika.
6. Utsi/mpukutu gwiritsani ntchito topcoat yapadera ya polyurea: Sakanizani wothandizila wamkulu ndi machiritso molingana, gwedezani bwino, ndipo gwiritsani ntchito chodzigudubuza chapadera kuti mugwirizanenso zokutira za polyurea topcoat pa ❖ kuyanika polyurea pamwamba. Imatsutsa kuwala kwa ultraviolet, imalepheretsa ukalamba ndi kusintha kwa mtundu.

Pansi pa msonkhano

1. Chithandizo cha maziko: Pewani chosanjikiza choyandama pamaziko, ndikuwulula malo olimba. Onetsetsani kuti maziko afika giredi C25 kapena pamwamba, ndi athyathyathya ndi owuma, opanda fumbi, ndipo sapanganso mchenga. Ngati pali zisa, malo ovuta, ming'alu, ndi zina zotero, gwiritsani ntchito zipangizo zokonzetsera ndikuzikonza kuti zikhale zolimba.
2. Polyurea primer ntchito: Ikani polyurea wapadera primer wogawana pa maziko kuti asindikize capillary pores pamwamba, kuonjezera dongosolo pansi, kuchepetsa zofooka ❖ kuyanika pambuyo kupopera mbewu mankhwalawa, ndi kuonjezera adhesion pakati polyurea putty ndi simenti, pansi konkire. Dikirani mpaka atachira bwino musanapitirire ku sitepe yotsatira yomanga. Ngati pali malo ambiri owonekera oyera pambuyo pa ntchito, iyenera kuikidwanso mpaka pansi lonse likuwoneka loderapo.
3. Polyurea putty ntchito: Ikani wofananira polyurea wapadera putty wogawana pa maziko kuonjezera flatness pansi, kusindikiza capillary pores amene saoneka ndi maso, ndi kupewa mmene kupopera mbewu mankhwalawa polyurea kumayambitsa pinholes chifukwa capillary pores pansi. Dikirani mpaka atachira bwino musanapitirire ku sitepe yotsatira yomanga.
4. Ntchito ya polyurea primer: Pa polyurea putty yochiritsidwa, ikani choyambira cha polyurea mofanana kuti muwonjezere kumamatira pakati pa wosanjikiza wa polyurea ndi polyurea putty.
5. Utsi pomanga polyurea: Pasanathe maola 24 chiyambi cha kuchiritsa, gwiritsani ntchito zida zaukadaulo zopopera mbewu mankhwalawa kuti mutsirize polyurea mofanana. Pamwamba pa zokutira ayenera kukhala yosalala, popanda kuthamanga, pinholes, thovu, kapena kusweka; pakuwonongeka kwanuko kapena ma pinholes, kukonza kwa manja kwa polyurea kungagwiritsidwe ntchito.
6. Polyurea topcoat ntchito: Pambuyo polyurea pamwamba uphwetsa, ntchito polyurea topcoat kupewa ukalamba, discoloration, ndi kuonjezera kuvala kukana kwa ❖ kuyanika polyurea, kuteteza ❖ kuyanika polyurea.

Zida zamigodi

1. Metal gawo lapansi, sandblasting kuchotsa dzimbiri kufika SA2.5 muyezo. Pamwamba mulibe fumbi loipitsa, madontho amafuta, ndi zina zotero. Mankhwala osiyanasiyana amachitidwa molingana ndi maziko.
2. Kupopera mbewu mankhwalawa (kupititsa patsogolo kumamatira kwa polyurea ku maziko).
3. Polyurea kupopera mbewu mankhwalawa (waukulu zinchito wosanjikiza zoteteza. Makulidwe ambiri tikulimbikitsidwa kukhala pakati 2mm ndi 5mm. Mapulani enieni yomanga amaperekedwa malinga ndi lolingana mankhwala).
4. Topcoat brushing / kupopera mbewu mankhwalawa (anti-yellowing, UV kukana, kuwonjezera zosiyanasiyana zofunika mtundu).
