Chitetezo cha Zomangamanga Padziko Lonse: Utoto Wopangidwa ndi Madzi wa Fluorocarbon Woletsa Kuwononga Topcoat

*Kapangidwe ka Zamalonda:

Utoto wa fluorocarbon wopangidwa ndi madzi ndi utoto wothandiza kwambiri komanso wosamalira chilengedwe womwe umagwiritsa ntchito utomoni wa fluorocarbon wopangidwa ndi madzi ngati chinthu chachikulu chomwe chimapanga filimu. Umakhala wolimba kwambiri, wopirira nyengo, komanso wokana dzimbiri wa utoto wachikhalidwe wa fluorocarbon, pomwe kugwiritsa ntchito madzi ngati chosungunulira kumachepetsa kwambiri kuchuluka kwa VOC (volatile organic compound), kukwaniritsa chitetezo chamakono chachilengedwe komanso zofunikira pakupanga zotetezeka. Kugwiritsa ntchito bwino ukadaulo wamadzi mu utoto wa fluorocarbon, womwe umatchedwa "mfumu ya utoto," ukuyimira ukadaulo wapamwamba kwambiri mumakampani opanga zomangamanga ndi kunja kwa khoma.

*Zinthu Zamalonda:

● Kulimba kwambiri kwa filimu, kukana kukalamba bwino, kulimba kwambiri, komanso kukana kugwedezeka.
● Kulimba kwabwino kwa nyengo komanso kusunga mtundu/kunyezimira: Kumalimbana bwino ndi kuwonongeka kwa UV, kukokoloka kwa mvula ya asidi, komanso kukokoloka kwa mphepo ndi mchenga; kumalimbana ndi choko ndi kusintha mtundu.
● Kukana dzimbiri ndi mankhwala: Kukana bwino mankhwala ambiri, zosungunulira, ndi mafuta. Chophimba chokhuthalachi chimatseka bwino kulowa kwa chinyezi, ma ayoni a chloride, ndi sulfide, zomwe zimapereka chitetezo chabwino kwambiri cha dzimbiri pa konkire ndi zitsulo.
● Imadziyeretsa bwino kwambiri komanso imateteza madontho: Mphamvu yochepa pamwamba, zomwe zimapangitsa kuti zikhale zovuta kuti dothi lizigwirana.
● Wochezeka komanso wotetezeka: Wothira madzi, wotsika kwambiri pa VOC, wopanda poizoni, wopanda fungo, wosayaka moto, komanso wosaphulika, zomwe zimapangitsa kuti ntchito yake ikhale yotetezeka.
●Kugwira ntchito bwino komanso kumamatira: Kumamatira bwino kwambiri ku zinthu zosiyanasiyana, kuphatikizapo konkriti yokonzedwa bwino, zitsulo, ma panelo a aluminiyamu, ndi zokutira zakale.

*Zambiri Zaukadaulo:

*Ntchito Yogulitsa:

Amagwiritsidwa ntchito poletsa dzimbiri pa zida zamakemikolo, mapaipi ndi malo achitsulo m'malo ovuta kwambiri owononga mafakitale. Akhoza kujambulidwa pa nyumba zachitsulo, mapulojekiti a milatho, malo osungiramo zinthu za m'madzi, mapulatifomu obowolera, madoko ndi madoko, nyumba zachitsulo, uinjiniya wa boma, zotchingira zothamanga kwambiri, zotchingira zoteteza konkire, ndi zina zotero.

*Chithandizo cha pamwamba:

Kuti muwonetsetse kuti filimuyo imamatirira komanso kuti dzimbiri silikutha nthawi yayitali, pamwamba pa nthakayo payenera kutsukidwa bwino kuchotsa mafuta, dzimbiri, mamba, utoto wakale, ndi zinyalala zotayirira musanagwiritse ntchito. Miyezo yokonzekera iyenera kukwaniritsa izi:

Malo onse oti apakedwe ayenera kukhala oyera, ouma komanso opanda kuipitsidwa. Musanapake utoto, malo onse ayenera kukhala ogwirizana ndi ISO_{8504: 2000}kuwunika ndi kukonza koyenera.

Chitsulo chopangidwa ndi scaled chaphulika kwa Sa_2.5kalasi, kuuma kwa pamwamba ndi 30-75μm, kapena kuviika, kusinthidwa ndi kusinthidwa;

Chitsulo chopanda oxide chaphulitsidwa ku Sa_2.5giredi, kapena wopukutidwa kupita ku St₃kalasi yokhala ndi gudumu lopukusira la pneumatic kapena lamagetsi;

Zitsulo zopakidwa utoto wa primer yogwirira ntchito, dzimbiri ndi dzimbiri loyera pa primer ya ufa wa zinc ziyenera kuchotsedwa kawiri, dzimbiri loyera limachotsedwa ndikupukutidwa kuti ligwiritsidwe ntchito.₃.

Malo ena Chogulitsachi chimagwiritsidwa ntchito pa zinthu zina, chonde funsani dipatimenti yathu yaukadaulo.

*Mkhalidwe wa Kamangidwe:

Kutentha kwa substrate sikotsika kuposa 5 ℃, ndipo osachepera 3 ℃ kuposa kutentha kwa mpweya wa dengu ndipo chinyezi ndi <85% (kutentha ndi chinyezi ziyenera kuyezedwa pafupi ndi substrate). Ntchito yomanga ndi yoletsedwa kwambiri mukakhala ndi chifunga, chipale chofewa komanso nyengo yamphepo.

*Masitepe Omanga:

Gawo 1: Kukonzekera Pansi pa Madzi (TheKiyiGawo)

Ubwino wa kukonzekera pamwamba umatsimikizira mwachindunji kumamatira ndi moyo wa filimu ya utoto.

Malo achitsulo ayenera kuchotsedwa mafuta ndi dzimbiri (motsatira miyezo ya Sa2.5 kapena St3) kuti zitsulo zomwe zipakidwe ziyenera kukhala zoyera bwino, zouma kwathunthu, komanso zopanda zinthu zodetsa monga mafuta, mafuta, fumbi, mchere, sikelo, ndi utoto wakale wotayirira. Chinyezi kapena kuzizira kooneka sikuloledwa.

Malo okonzedwawo ayenera kukwaniritsa miyezo ya ukhondo ndi kuuma kwa kapangidwe kake, ndipo utoto uyenera kupakidwa mwachangu momwe zingathere kuti dzimbiri lisabwererenso kapena kuipitsidwa kwina.

Skutentha2: Ikani Primer

Malinga ndi gawo lapansi ndi malo enieni, sankhani pulasitala yogwirizana (Epoxy Zinc-Rich Primer, Epoxy Zinc Phosphate Primer).

Gawo 3: Ikani Utoto Wochokera M'madzi wa Fluorocarbon

Pang'onopang'ono tsanulirani gawo B (chotsukira) mu gawo A (utoto wa fluorocarbon wopangidwa ndi madzi), bwino malinga ndi chiŵerengero chomwe chatchulidwa (ndi kulemera). Mukasakaniza bwino, lolani chisakanizocho chiyime kwa mphindi 5-10 kuti chikhwime. Ndipo chophimba chosakanizacho chigwiritsidwe ntchito mkati mwa maola 4 (nthawi ya mphika). Kenako burashi/kupukuta kapena kupopera, kupopera popanda mpweya kumapereka mphamvu kwambiri ndipo kumapanga filimu yabwino kwambiri ya utoto. Ngati muli ndi zida ndi luso laukadaulo, zidzakhala bwino kwambiri. Kugwiritsa ntchito utoto mozama ndi 0.2kg/m²/coat. (Kagwiritsidwe ntchito kwenikweni kamasiyana kutengera kapangidwe ka pamwamba, ma porosity, njira yogwiritsira ntchito ndi njira yogwiritsira ntchito.)

Zindikirani:

*Ngati pakufunika kuchepetsedwa, sakanizani ndi madzi oyeretsedwa malinga ndi kukhuthala ndi njira yogwiritsira ntchito (kutsuka, kuzunguliza, kapena kupopera). Sinthani kukhuthala kuti kugwirizane ndi njira yeniyeni yogwiritsira ntchito.

* Chiŵerengero cha kusungunuka kwa 5-20% polemera. Kuchepetsa kwambiri kungakhudze kwambiri kapangidwe ka filimu, mphamvu yobisala, komanso kulimba kwa nthawi yayitali.

* Musanagwiritse ntchito chovala china, onetsetsani kuti chovala choyambirira chatsukidwa bwino, chayera, chouma, komanso chopanda zodetsa zilizonse.

* Pewani kusakaniza mwamphamvu kuti musalowetse thovu lochuluka.

* Nthawi Yobwezeretsanso Chivundikiro: M'malo owononga pang'ono: utoto umodzi wa primer + utoto wapakati wa midcoat + utoto wa pamwamba wa topcoat wa 1; m'malo owononga kwambiri, onjezerani makulidwe a chophimbacho.

*Njira Yomangira:

Kupopera: Kupopera popanda mpweya kapena kupopera mpweya. Kupopera popanda mpweya wochuluka n'koyenera.
Kutsuka / Kuzungulira: Kuchuluka kwa filimu youma yomwe yatchulidwa kuyenera kukwaniritsidwa.

*Kachitidwe Kophimba:

Tikukulimbikitsani kugwiritsa ntchito njira yonse ya "sealing primer + intermediate coat + water-based fluorocarbon topcoat" kuti mupeze zotsatira zabwino komanso zotsika mtengo.

PrimerZitsanzo zikuphatikizapo choyambira chamadzi cholemera mu epoxy zinc ndi choyambira chamadzi cholemera mu epoxy. Ntchito yake yayikulu ndikupereka chitetezo chabwino kwambiri choteteza dzimbiri komanso kumatira.

Chovala chapakati:Kawirikawiri imakhala ndi epoxy micaecous iron oxide coat yochokera m'madzi. Imawonjezera makulidwe onse a chophimba, imagwira ntchito ngati chotchinga ku chinyezi ndi zinthu zowononga, komanso imathandizira chitetezo chonse.

Chovala chapamwamba:Chovala chapamwamba cha fluorocarbon chimapereka chitetezo chomaliza ku nyengo yozizira ndi dzimbiri, komanso mawonekedwe okongola omwe amafunidwa.

*Kusamalitsa:

▶ Kutentha kwa kapangidwe kake ndi 5℃-35℃ (Kusintha kwina kumapangidwa malinga ndi mawonekedwe a chinthucho, chinyezi ndi ≤80% ndipo kupewa mvula.

▶ Sungani mpweya wabwino kuti chinyezi chisasunthe komanso kuti utoto ukhale wosalala.

▶ Tetezani ku kuzizira pamene mukusunga.

▶ Zipangizo zodzitetezera ziyenera kuvalidwa pokonza mchenga

▶ Chifunga, mvula, chipale chofewa, mphepo ndi mvula ndizoletsedwa kwambiri.

*Kusungirako ndi Kusunga Zinthu Pa Shelufu:

▅ Sungani m'nyumba yosungiramo zinthu yozizira, youma, komanso yodutsa mpweya kutentha kwa 5-35 ℃, pewani kuzizira komanso kuwala kwa dzuwa mwachindunji;

▅ Moyo wa zinthu ndi miyezi 12. Ngati zinthu zomwe zapitirira nthawi yosungidwa zingagwiritsidwe ntchito mutadutsa mayeso.

*Phukusi:

Utoto：20Kg/Chidebe(18Liter/Chidebe); Chowumitsira: 4Kg/Chidebe(4Liter/Chidebe) kapena chosinthidwa.
