Utoto wa polyurethane pansi ndi zokutira zogwira ntchito kwambiri zomwe zimagwiritsidwa ntchito kwambiri m'nyumba zamafakitale, zamalonda ndi zamagulu. Amapangidwa ndi utomoni wa polyurethane, wochiritsa, ma pigment ndi ma fillers, ndi zina zambiri, ndipo ali ndi kukana kwabwino kwa kuvala, kukana mankhwala komanso kukana nyengo. Zofunikira zazikulu za utoto wa polyurethane pansi ndi:
1. Kukana kwamphamvu kuvala: Utoto wa pansi wa polyurethane uli ndi kukana kwabwino kwa kuvala ndipo ndi woyenera malo omwe ali ndi anthu ambiri, monga ma workshop, nyumba zosungiramo katundu ndi masitolo.
2. Kulimbana ndi Mankhwala : Zimatsutsana bwino ndi mankhwala osiyanasiyana (monga mafuta, asidi, alkali, etc.), ndipo ndizoyenera kumadera monga zomera za mankhwala ndi ma laboratories.
3. Kuthamanga kwabwino : Utoto wa pansi wa polyurethane uli ndi mlingo wina wa elasticity, womwe ungathe kukana zofooka zazing'ono za pansi ndikuchepetsa kuchitika kwa ming'alu.
4. Aesthetics : Mitundu yosiyanasiyana ikhoza kukonzedwa malinga ndi zosowa. Pamwambapo ndi yosalala komanso yosavuta kuyeretsa, kuwongolera kukongola kwa chilengedwe.
Masitepe omanga
Njira yopangira utoto wa polyurethane pansi ndi yovuta kwambiri ndipo iyenera kutsatira izi:
1. Chithandizo chapansi pamunsi
CHOYERA: Onetsetsani kuti pansi mulibe fumbi, mafuta ndi zonyansa zina. Gwiritsani ntchito mfuti yamadzi yothamanga kwambiri kapena chotsukira chotsukira m'mafakitale poyeretsa.
Kukonza: Konzani ming'alu ndi maenje pansi kuti pansi pakhale posalala.
Kupera: Gwiritsani ntchito chopukusira kupukuta pansi kuti muwonjezere kumatira kwa zokutira.
2. Ntchito yoyamba
Sankhani choyambira: Sankhani choyambira choyenera malinga ndi momwe zilili, nthawi zambiri choyambira cha polyurethane chimagwiritsidwa ntchito.
Kutsuka: Gwiritsani ntchito chodzigudubuza kapena mfuti yopopera kuti mugwiritse ntchito poyambira mofanana kuti mutsimikizire kuphimba. Pambuyo pouma, fufuzani mawanga omwe asowa kapena osagwirizana.
3. Kumanga malaya apakati
Kukonzekera zokutira zapakatikati: Konzani zokutira zapakatikati molingana ndi malangizo azinthu, nthawi zambiri kuwonjezera wochiritsa.
Kutsuka: Gwiritsani ntchito chopukutira kapena chodzigudubuza kuti mugwiritsire ntchito chovala chapakati kuti muonjezere makulidwe ndi kulimba kwa pansi. Chovala chapakati chikawuma, sungani mchenga.
4. Topcoat ntchito
Konzani chovala chapamwamba: Sankhani mtundu momwe mukufunikira ndipo konzekerani chovala chapamwamba.
Kugwiritsa ntchito: Gwiritsani ntchito chodzigudubuza kapena mfuti yopopera kuti mugwiritse ntchito chovalacho mofanana kuti chikhale chosalala. Pambuyo pa topcoat yauma, yang'anani kufanana kwa zokutira.
5. Kusamalira
Nthawi yokonza: Pambuyo pomaliza kujambula, kukonza bwino kumafunika. Nthawi zambiri zimatenga masiku opitilira 7 kuti utoto wapansi uchiritsidwe kwathunthu.
Pewani kupanikizika kwambiri: Panthawi yochiritsa, pewani kuyika zinthu zolemera pansi kuti musasokoneze ubwino wa zokutira.
Kutentha ndi Chinyezi: Samalani kutentha ndi chinyezi chozungulira pomanga. Zomangamanga nthawi zambiri zimakhala bwino pansi pazikhalidwe za 15-30 ℃.
Chitetezo cha Chitetezo: Magolovesi oteteza, masks ndi magalasi ayenera kuvalidwa pomanga kuti atetezeke.
