Utoto wosawonongeka wa polyurea Zophimba pansi za polyurea Chithunzi Chowonetsedwa

Utoto wosagwira ntchito wa polyurea wopaka utoto wa polyurea

Kufotokozera Kwachidule:

Zophimba za polyurea zimapangidwa makamaka ndi zigawo za isocyanate ndi ma polyether amines. Zipangizo zopangira polyurea zomwe zilipo panopa zimakhala ndi MDI, polyether polyols, polyether polyamines, amine chain extenders, zowonjezera zosiyanasiyana zogwira ntchito, ma pigment ndi ma fillers, ndi zosungunulira zogwira ntchito.

Zophimba za Polyurea zimapangidwa makamaka ndi zigawo za isocyanate ndi ma polyether amines. Zipangizo zopangira polyurea zomwe zilipo panopa zimaphatikizapo MDI, polyether polyols, polyether polyamines, amine chain extenders, zowonjezera zosiyanasiyana zogwira ntchito, utoto ndi zodzaza, ndi zosungunulira zogwira ntchito. Zophimba za Polyurea zili ndi mawonekedwe a liwiro lotha kuchira mwachangu, liwiro la zomangamanga mwachangu, chitetezo chabwino kwambiri ku dzimbiri komanso magwiridwe antchito osalowa madzi, kutentha kwakukulu, komanso njira yosavuta. Ndizoyenera makamaka mabizinesi osiyanasiyana amakampani ndi migodi, malo oimika magalimoto, mabwalo amasewera, ndi zina zotero, zophimba pansi zomwe zimafunikira kuti zisagwedezeke, zisagwedezeke komanso zisawonongeke.

ZINTHU ZOPANGIRA NTCHITO

Kukana kwapamwamba kwambiri kwa kuvala, kukana kukanda, komanso moyo wautali wautumiki;
Ili ndi kulimba bwino kuposa pansi pa epoxy, popanda kung'ambika kapena kusweka:
Kuchuluka kwa kukangana kwa pamwamba ndi kwakukulu, zomwe zimapangitsa kuti ikhale yolimba kuposa pansi pa epoxy.
Kupanga filimu yokhala ndi ubweya umodzi, kuumitsa mwachangu, kapangidwe kosavuta komanso kachangu:
Kupakanso kumakhala kolimba kwambiri ndipo ndikosavuta kukonza.
Mitundu ingasankhidwe mwaufulu. Ndi yokongola komanso yowala. Siiwononga chilengedwe komanso siiwononga chilengedwe.

Njira zomangira

Malo Oyimilira Masewera

1. Kukonza pamwamba: Chotsani fumbi, madontho a mafuta, mchere, dzimbiri, ndi zinthu zotulutsa madzi kuchokera pansi poyeretsa kaye kenako n’kutsuka. Mukamaliza kupukuta bwino, fumbi losalowa m’malo opumira limayamba kuchotsedwa.
2. Kugwiritsa ntchito primer yapadera: Pukutani primer yapadera ya polyurea kuti mutseke ma capillary pores, muchepetse zolakwika pakuphimba, ndikuwonjezera kumatirira pakati pa polyurea ndi maziko.
3. Kupaka ndi polyurea putty (kutengera momwe pansi pake pakuyendera): Gwiritsani ntchito zinthu zapadera zopaka kuti polyurea ikonze ndikulinganiza pansi pake. Mukamaliza kupukuta, gwiritsani ntchito gudumu lopukutira lamagetsi kuti muponde bwino kenako gwiritsani ntchito chotsukira cha vacuum kuti muyeretse.
4. Perekani choyambira chapadera cha polyurea: Tsekaninso pamwamba pa nthaka, ndikuwonjezera kwambiri kumatirira pakati pa polyurea ndi maziko.
5. Kupopera utoto wosalowa madzi wa polyurea: Mukayesa kupopera, poperani motsatira dongosolo kuyambira pamwamba mpaka pansi kenako pansi, mukuyenda m'dera laling'ono mopingasa komanso motalikirapo. Kukhuthala kwa utoto ndi 1.5-2mm. Kupopera kumachitika nthawi imodzi. Njira zinazake zitha kupezeka mu "Polyurea Engineering Coating Specifications". Imagwira ntchito yofunika kwambiri pakuteteza madzi, siitha kusweka komanso siitha kutsetsereka.
6. Pukutani/pukutani pakani topcoat yapadera ya polyurea: Sakanizani mankhwala akuluakulu ndi mankhwala ochiritsira molingana, sakanizani bwino, ndipo gwiritsani ntchito chopukutani chapadera kuti muzungulire mofanana polyurea topcoat pamwamba pa polyurea yophimbidwa bwino. Imalimbana ndi kuwala kwa ultraviolet, imaletsa kukalamba ndi kusintha kwa mtundu.

Pansi pa msonkhano

1. Kukonza maziko: Pukutani gawo loyandama pa maziko, powonetsa malo olimba. Onetsetsani kuti maziko afika pa giredi C25 kapena kupitirira apo, ndi athyathyathya komanso ouma, opanda fumbi, komanso sapanganso mchenga. Ngati pali uchi, malo okhwima, ming'alu, ndi zina zotero, gwiritsani ntchito zipangizo zokonzera kuti mukonze ndikulilinganiza kuti likhale lolimba.
2. Kugwiritsa ntchito polyurea primer: Ikani polyurea special primer mofanana pa maziko kuti mutseke ma capillary pores pamwamba, kulimbitsa kapangidwe ka nthaka, kuchepetsa zolakwika mu chophimba mutatha kupopera, ndikuwonjezera kumatirira pakati pa polyurea putty ndi simenti, pansi pa konkire. Yembekezerani mpaka itachira bwino musanapitirire ku gawo lotsatira la zomangamanga. Ngati pali malo ambiri oyera atagwiritsidwa ntchito, iyenera kupakidwanso mpaka pansi ponse pawoneke bulauni wakuda.
3. Kugwiritsa ntchito polyurea putty: Ikani polyurea special putty yofanana pa maziko kuti pansi pakhale posalala, sungani ma capillary pores omwe sangawonekere ndi maso, ndipo pewani momwe kupopera polyurea kumayambitsa mabowo chifukwa cha ma capillary pores omwe ali pansi. Yembekezerani mpaka atachira bwino musanapitirire ku sitepe yotsatira yomanga.
4. Kugwiritsa ntchito polyurea primer: Pa polyurea putty yochiritsidwa, ikani polyurea primer mofanana kuti muwonjezere bwino kumamatira pakati pa polyurea wosanjikiza wopopera ndi polyurea putty.
5. Kupanga polyurea: Pakatha maola 24 kuchokera pamene primer yauma, gwiritsani ntchito zida zaukadaulo zopopera kuti mupopere polyurea mofanana. Pamwamba pa chophimbacho payenera kukhala posalala, popanda madzi otuluka, mabowo ang'onoang'ono, thovu, kapena ming'alu; pa kuwonongeka kwapafupi kapena mabowo ang'onoang'ono, kukonza polyurea pamanja kungagwiritsidwe ntchito.
6. Kugwiritsa ntchito polyurea topcoat: Pambuyo poti pamwamba pa polyurea pauma, ikani polyurea topcoat kuti mupewe kukalamba, kusintha mtundu, ndikuwonjezera kukana kwa polyurea, kuteteza polyurea topcoat.

Zipangizo zamigodi

1. Chitsulo chopangidwa ndi chitsulo, kuphulika kwa mchenga kuti kuchotse dzimbiri kumafika pa muyezo wa SA2.5. Pamwamba pake palibe fumbi loipitsidwa, madontho a mafuta, ndi zina zotero. Mankhwala osiyanasiyana amachitidwa malinga ndi maziko.
2. Kupopera mbewu (kuti polyurea imamatire ku maziko).
3. Kapangidwe ka kupopera kwa polyurea (gawo lalikulu loteteza. Kukhuthala kwake nthawi zambiri kumalimbikitsidwa kukhala pakati pa 2mm ndi 5mm. Mapulani enieni omangira amaperekedwa malinga ndi zinthu zomwe zikugwirizana).
4. Kapangidwe ka burashi/kupopera pamwamba pa topcoat (koletsa chikasu, kukana kwa UV, kuwonjezera mitundu yosiyanasiyana ya zofunikira).
