Utoto wa pansi wa polyurethane ndi utoto wapamwamba kwambiri womwe umagwiritsidwa ntchito kwambiri m'mafakitale, mabizinesi ndi nyumba zapakhomo. Umapangidwa ndi polyurethane resin, mankhwala ochiritsira, utoto ndi zodzaza, ndi zina zotero, ndipo uli ndi kukana kuwonongeka, kukana mankhwala komanso kukana nyengo. Zinthu zazikulu zomwe utoto wa pansi wa polyurethane umaphatikizapo:

1. Kukana kuvala kwambiri: Utoto wa pansi wa polyurethane umakhala wokana kuvala bwino ndipo ndi woyenera malo odzaza magalimoto, monga ma workshop, nyumba zosungiramo katundu ndi malo ogulitsira zinthu.

2. Kukana Mankhwala: Imakhala yolimba kwambiri ku zinthu zosiyanasiyana zamakemikolo (monga mafuta, asidi, alkali, ndi zina zotero), ndipo ndi yoyenera malo monga zomera zamakemikolo ndi ma laboratories.

4. Kukongola: Mitundu yosiyanasiyana ikhoza kukonzedwa malinga ndi zosowa. Pamwamba pake ndi posalala komanso posavuta kuyeretsa, zomwe zimapangitsa kuti chilengedwe chikhale chokongola.

Masitepe omanga

Ntchito yomanga utoto wa pansi pa polyurethane ndi yovuta kwambiri ndipo iyenera kutsatira njira zotsatirazi:

1. Chithandizo cha pamwamba pa nthaka
CHOYERETSA: Onetsetsani kuti pansi mulibe fumbi, mafuta ndi zinthu zina zodetsa. Gwiritsani ntchito mfuti yamadzi yothamanga kwambiri kapena chotsukira cha vacuum cha mafakitale poyeretsa.
Kukonza: Konzani ming'alu ndi mabowo pansi kuti pakhale malo osalala pansi.
Kupera: Gwiritsani ntchito chopukusira kuti mupukute pansi kuti chophimbacho chikhale cholimba kwambiri.

2. Kugwiritsa ntchito primer
Sankhani pulasitala: Sankhani pulasitala yoyenera malinga ndi momwe zinthu zilili, nthawi zambiri pulasitala ya polyurethane imagwiritsidwa ntchito.
Kutsuka: Gwiritsani ntchito chopukutira kapena mfuti yopopera kuti mugwiritse ntchito chotsukira mofanana kuti muwonetsetse kuti chikuphimba. Chotsukira chikauma, yang'anani ngati pali malo omwe akusowa kapena osafanana.

3. Kapangidwe ka mid-coat
Kukonzekera chophimba chapakati: Konzani chophimba chapakati motsatira malangizo a mankhwala, nthawi zambiri kuwonjezera chotsukira.
Kutsuka: Gwiritsani ntchito chotsukira kapena chozungulira kuti mugwiritse ntchito mofanana pakati pa nsalu kuti muwonjezere makulidwe ndi kukana kutha kwa pansi. Pakati pa nsalu pakakhala kouma, muike mchenga.

4. Kugwiritsa ntchito topcoat
Konzani topcoat: Sankhani mtundu womwe mukufuna ndipo konzani topcoat.
Kugwiritsa Ntchito: Gwiritsani ntchito chopukutira kapena mfuti yopopera kuti muyike topcoat mofanana kuti muwonetsetse kuti pamwamba pake pali posalala. Topcoat ikauma, yang'anani kufanana kwa chophimbacho.

5. Kukonza
Nthawi Yokonza: Pambuyo poti utoto watha, kukonza koyenera kumafunika. Nthawi zambiri zimatenga masiku opitilira 7 kuti utoto wa pansi uume bwino.
Pewani kupanikizika kwambiri: Mu nthawi yothira, pewani kuyika zinthu zolemera pansi kuti musawononge ubwino wa chophimbacho.

Kutentha ndi Chinyezi: Samalani kutentha ndi chinyezi cha malo ozungulira panthawi yomanga. Mphamvu yomanga nthawi zambiri imakhala yabwino kwambiri pa kutentha kwa 15-30℃.
Chitetezo: Magolovesi oteteza, zophimba nkhope ndi magalasi ayenera kuvalidwa panthawi yomanga kuti atsimikizire chitetezo.
