Chophimba cha polyurea choletsa dzimbiri cha mapaipi ndi matanki a zimbudzi

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.

Chophimba cha polyurea choletsa dzimbiri

Zophimba za Polyurea zotsutsana ndi dzimbiri

Munda wa anti-corrosion ndi komwe ukadaulo wa polyurea unayamba kale kwambiri ndipo wakhala ukugwiritsidwa ntchito kwambiri mu uinjiniya. Ntchito zake zikuphatikizapo anti-corrosion ya zomangamanga zachitsulo monga mapaipi, matanki osungiramo zinthu, malo osungiramo zinthu, milu yachitsulo, ndi matanki osungiramo mankhwala. Chophimba cha zinthuzo ndi chokhuthala, chopanda chopinga, chili ndi mphamvu yoletsa kulowa kwa madzi ndi dzimbiri, chimatha kupirira kuwonongeka kwa zinthu zambiri za mankhwala, ndipo chingagwiritsidwe ntchito kwa nthawi yayitali m'malo akunja okhala ndi dzimbiri lamphamvu monga madambo, maiwe, mafuta amchere, ndi malo amiyala opanda ufa, ming'alu, kapena kusweka. Chimalimbana bwino ndi nyengo. Chophimba cha Delsil polyurea choletsa dzimbiri sichidzasweka ngakhale patakhala kusintha kwa kapangidwe ka chitsulo, ndipo chimatha kuphimba malo onse ogwirira ntchito ngakhale m'mikhalidwe yosadziwika bwino monga kutuluka kapena kutsika kwa mapaipi.

Njira zomangira

Ukadaulo Watsopano Woletsa Kudzikundikira kwa Maiwe Otayira Madzi
Pamene vuto la kuteteza chilengedwe likukulirakulira, madzi otayirira a m'mafakitale, madzi otayirira azachipatala, ndi ndowe zamadzimadzi akumidzi zonse zimagwiritsa ntchito njira yosonkhanitsira pamodzi. Kuletsa dzimbiri kwa maiwe a konkire kapena mabokosi achitsulo omwe ali ndi zimbudzi kapena madzi otayirira kwakhala chinthu chofunika kwambiri. Kupanda kutero, kungayambitse kutayikira kwachiwiri kwa zimbudzi, zomwe zimapangitsa kuti nthaka iipitsidwe. Malinga ndi ziwerengero zosakwanira, nthawi yogwira ntchito ya maiwe otayirira dzimbiri ndi nthawi 15 kuposa maiwe otayirira dzimbiri. Mwachionekere, kuteteza dzimbiri kwa maiwe otayirira sikuti ndi gawo lofunika kwambiri la malo otetezera chilengedwe komanso phindu lobisika kwa mabizinesi.

1. Kupera ndi kuyeretsa pansi pa nyumba: Choyamba yeretsani kenako yeretsani kuti muchotse fumbi, madontho a mafuta, mchere, dzimbiri, ndi zinthu zotulutsa fumbi pansi pake. Mukapera bwino, sonkhanitsani fumbi pogwiritsa ntchito chotsukira.
2. Chophimba chopanda zosungunulira: Chiyenera kupakidwa pamwamba pa nthaka musanamange. Chingathe kutseka ma capillary pores a pansi, kuchepetsa zolakwika zophimba pambuyo popopera, ndikuwonjezera kumatirira pakati pa chophimba ndi simenti ndi pansi pa konkire. Yembekezerani mpaka chitachira bwino musanapitirire ku gawo lotsatira la kumanga.
3. Kukonza polyurea putty (kusankhidwa kutengera momwe zinthu zimakhalira): Gwiritsani ntchito polyurea patching putty yapadera kuti mukonze ndi kulinganiza. Mukamaliza kuuma, gwiritsani ntchito gudumu lopukutira lamagetsi kuti mupukute bwino kenako mutsuke vacuum clean.
4. Kutseka primer yopanda zosungunulira: Sakanizani primer yopanda zosungunulira ndi mankhwala ochiritsira mu chiŵerengero chovomerezeka, sakanizani mofanana, ndikuzungulira kapena kukanda primer mofanana mkati mwa nthawi yomwe mwasankha yogwiritsira ntchito. Tsekani pamwamba pa maziko ndikuwonjezera kumamatira. Lolani kuti liume kwa maola 12-24 (kutengera momwe pansi pake palili, ndi mfundo yotseka pansi).
5. Thirani chopopera cha polyurea choletsa dzimbiri; Mukamaliza kupopera choyesera, choyamba thirani dzenje lolumikizira, kenako thirani pamwamba pa chitoliro, mapaipi owongoka kapena zigongono zimathiridwa mufakitale, ndipo malo olumikizirana amathiridwa pamalopo. Thirani motsatira dongosolo kuyambira pamwamba mpaka pansi, kenako pansi, ndikusuntha m'dera laling'ono mopingasa. Kukhuthala kwa chopopera ndi 1.5-2.0mm. Malizitsani kupopera kamodzi. Njira zenizeni zitha kupezeka mu "Polyurea Engineering Coating Specifications".
6. Chophimba pamwamba pa polyurea ndi chopopera: Sakanizani chopangira chachikulu ndi chopopera pamwamba pa polyurea mu chiŵerengero chovomerezeka, sakanizani bwino, ndipo gwiritsani ntchito chopukutira chopangidwa kuti chikhale chofanana kapena makina opopera kuti mupopere chophimba pamwamba pa polyurea chomwe chachiritsidwa bwino. Pewani kuwala kwa ultraviolet, pewani kukalamba, komanso kusintha mtundu.

Kupewa Kudzimbiri kwa Mapaipi
M'zaka zaposachedwapa, pakhala chitukuko chachikulu pa zipangizo zopewera dzimbiri za mapaipi. Kuyambira pa njira yoyambirira yopewera dzimbiri ya malasha mpaka njira yopewera dzimbiri ya pulasitiki ya 3PE, ndipo tsopano mpaka ku zipangizo zopangidwa ndi polima, magwiridwe antchito awo asintha kwambiri. Pakadali pano, njira zambiri zopewera dzimbiri zili ndi makhalidwe monga kuvutika kwambiri pomanga, nthawi yochepa yogwira ntchito, kukonza kovuta kumapeto, komanso kusawononga chilengedwe. Kutuluka kwa polyurea kwadzaza kusiyana kumeneku m'munda.

1. Kupukuta mchenga kuti muchotse dzimbiri: Choyamba, mapaipi amapukutidwa mchenga kuti muchotse dzimbiri motsatira muyezo wa Sa2.5. Ntchito yopukuta mchenga iyenera kumalizidwa mkati mwa maola 6. Kenako, chophimba cha polyurethane primer chimayikidwa.
2. Kugwiritsa ntchito pulasitala: Pambuyo popukuta mchenga, pulasitala yapadera yopanda zosungunulira imayikidwa. Pulayimale ikauma mpaka kufika poti palibe madzi owoneka bwino omwe amatsala pamwamba, chophimba cha polyurethane chimapopera. Onetsetsani kuti mwagwiritsa ntchito mofanana kuti mutsimikizire kuti polyurethane ndi chitolirocho zimamatira.
3. Kupopera ndi polyurethane: Gwiritsani ntchito makina opopera ndi polyurethane kuti mupopera ndi polyurethane mofanana mpaka makulidwe a filimuyo afike. Pamwamba pake payenera kukhala posalala, popanda madzi otuluka, mabowo ang'onoang'ono, thovu, kapena ming'alu. Pa kuwonongeka kwa malo kapena mabowo ang'onoang'ono, kukonza ndi polyurethane pamanja kungagwiritsidwe ntchito pokonza.
