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.

Munda wa anti-corrosion ndi pomwe ukadaulo wa polyurea udalowa koyambirira ndipo wagwiritsidwa ntchito kwambiri muukadaulo. Ntchito zake zikuphatikiza zotsutsana ndi dzimbiri zazitsulo monga mapaipi, akasinja osungira, ma docks, milu yazitsulo, ndi akasinja osungira mankhwala. Chophimba chakuthupi ndi chowuma, chosasunthika, chimakhala ndi mphamvu zotsutsa-permeation ndi dzimbiri, zimatha kupirira kukokoloka kwamankhwala ambiri, ndipo zitha kugwiritsidwa ntchito kwa nthawi yayitali m'malo akunja okhala ndi dzimbiri lamphamvu monga madambo, maiwe, mafuta amchere, ndi madera amiyala popanda ufa, kusweka, kapena kusenda. Ili ndi kukana kwanyengo kwabwino. The Delsil polyurea anti-corrosion ❖ kuyanika sikudzathyoka ngakhale ngati pali mapindikidwe muzitsulo zachitsulo, ndipo amatha kuphimba gawo lonse la workpiece ngakhale muzochitika zachilendo monga ma protrusions kapena ma depressions a mapaipi.

Njira zomanga

Tekinoloje Yatsopano Yotsutsana ndi Kuwonongeka kwa Maiwe Otayira
Pamene chitetezo cha chilengedwe chikuchulukirachulukira, madzi otayira m'mafakitale, madzi otayira azachipatala, ndi kuthira manyowa akumidzi zonse zimatengera njira yosonkhanitsira pakati. Zotsutsana ndi dzimbiri zamadzimadzi a konkire kapena mabokosi achitsulo omwe ali ndi zonyansa kapena madzi onyansa akhala chinthu chofunika kwambiri. Kupanda kutero, kungayambitse kutayikira kwachiwiri kwa zimbudzi, zomwe zimapangitsa kuti nthaka ikhale yosasinthika. Malinga ndi ziwerengero zosakwanira, moyo wautumiki wa maiwe odana ndi dzimbiri amadzimadzi ndi nthawi 15 kuposa maiwe otayirira otayira. Mwachiwonekere, anti-corrosion ya maiwe onyansa si gawo lofunika kwambiri la malo otetezera zachilengedwe komanso phindu lobisika kwa mabizinesi.

1. Kupera ndi kuyeretsa m’chipinda chapansi: Choyamba sesani ndiyeno kuyeretsani kuchotsa fumbi, madontho amafuta, mchere, dzimbiri, ndi kumasula zinthu zapansi. Pambuyo bwinobwino akupera, vacuum fumbi kusonkhanitsa.
2. Zosungunulira zopanda zosungunulira: Ziyenera kuyikidwa pansi musanamangidwe. Ikhoza kusindikiza ma pores a capillary pansi, kuchepetsa zowonongeka pambuyo popopera mankhwala, ndikuwonjezera kumamatira pakati pa zokutira ndi simenti ndi pansi. Dikirani mpaka atachira bwino musanapitirire ku sitepe yotsatira yomanga.
3. Polyurea putty kukonza wosanjikiza (osankhidwa kutengera mavalidwe): Gwiritsani ntchito polyurea patching putty yodzipereka pokonza ndi kusanja. Mukamaliza kuchiritsa, gwiritsani ntchito gudumu lopera lamagetsi kuti mupere bwino ndikuyeretsa.
4. Kusindikiza kosindikiza kopanda zosungunulira: Sakanizani zosungunulira zopanda zosungunulira ndi zochizira mu chiŵerengero chomwe mwasankha, gwedezani mofanana, ndi kupukuta kapena kukwapula mofanana mkati mwa nthawi yogwiritsidwa ntchito. Tsekani pansi pamwamba ndikuwonjezera kumatira. Lolani kuchiza kwa maola 12-24 (malingana ndi chikhalidwe cha pansi, ndi mfundo yosindikiza pansi).
5. Utsi polyurea odana ndi dzimbiri ❖ kuyanika; Mukadutsa kupopera kwa mayeso, tsitsani kaye dzenje lolumikizira, kenaka tsitsani pamwamba pa chitoliro, mipope yowongoka kapena zigono zimapopera mu fakitale, ndipo zolumikizira zimapopera pamalopo. Utsi mu dongosolo kuchokera pamwamba mpaka pansi, kenako pansi, ndi kusuntha mu kadera kakang'ono mu mtanda chitsanzo. makulidwe ❖ kuyanika ndi 1.5-2.0mm. Malizitsani kupopera mbewu mankhwalawa kamodzi. Njira zenizeni zitha kupezeka mu "Polyurea Engineering Coating Specifications".
6. Perekani zokutira ndi kupopera polyurea pamwamba odula: Sakanizani wothandizila chachikulu ndi wochiritsa wothandizila mu chiŵerengero analamula, kusonkhezera bwino, ndi ntchito wodzigudubuza wodzipatulira kwa yunifolomu kugudubuza kapena kutsitsi makina kupopera polyurea pamwamba malaya ❖ kuyanika pamwamba anachiritsidwa polyurea ❖ kuyanika pamwamba. Pewani kuwala kwa ultraviolet, kupewa kukalamba, ndi kusintha kwa mtundu.

Kupewa Kuwonongeka kwa Mapaipi
M'zaka makumi angapo zapitazi, pakhala chitukuko chachikulu cha zida zopewera kuwononga mapaipi. Kuyambira pa njira yoyamba yopewera dzimbiri ya malasha kupita ku njira yopewera dzimbiri ya pulasitiki ya 3PE, ndipo tsopano mpaka zida zophatikizika za polima, magwiridwe antchito apita patsogolo kwambiri. Pakalipano, njira zambiri zopewera dzimbiri zimakhala ndi makhalidwe monga kuvutikira kwa zomangamanga, moyo wautali, kukonza zovuta pambuyo pake, komanso kusakonda zachilengedwe. Kutuluka kwa polyurea kwadzaza kusiyana kumeneku m'munda.

1. Sandblasting kuchotsa dzimbiri: Choyamba, mapaipi ndi sandblasted kuchotsa dzimbiri kwa muyezo Sa2.5. Ntchito yopangira mchenga iyenera kumalizidwa mkati mwa maola 6. Kenako, zokutira zoyambira za polyurethane zimagwiritsidwa ntchito.
2. Kugwiritsa ntchito koyamba: Pambuyo pa sandblasting, choyambira chapadera chosasungunulira chimayikidwa. Pambuyo poyambira kuuma mpaka pomwe palibe madzi owoneka bwino omwe amakhala pamwamba, zokutira za polyurethane zimapopera. Onetsetsani ngakhale ntchito kutsimikizira zomatira pakati pa polyurethane ndi chitoliro gawo lapansi.
3. Kupopera mbewu mankhwalawa ndi polyurethane: Gwiritsani ntchito makina opopera mankhwala a polyurethane kupopera mbewuzo molingana ndi polyurethane mpaka makulidwe a filimuwo akwaniritsidwa. Pamwamba payenera kukhala yosalala, popanda kuthamangira, mapini, thovu, kapena kusweka. Pazowonongeka zakomweko kapena ma pinholes, kukonza kwapamanja kwa polyurethane kungagwiritsidwe ntchito pazigamba.
