Rahoton kan fasahar feshi ta saman filastik —— Maganin ƙawata ƙasa mai inganci wajen hana tsatsa

I. Aiki da Magance Matsaloli

1. Ayyukan asali

Tsayayya ga tsatsa na dogon lokaci: siffa 60-120μm shafi na epoxy/polyester, gwajin fesa gishiri har zuwa Awanni 240-1000 (Feshin feshi na yau da kullun awanni 72-200 kawai)
Ƙarfin ado: tallafi Lambar launi ta Pantone 2000+, za a iya zaɓar yanayin saman mai santsi, lemu, mai sheƙi na ƙarfe
Rufin lantarki: ƙarfin lantarki mai lalacewa>30kV/mm, kare harsashin kayan aikin lantarki
Tsaron muhalli: babu narkewar sinadarai masu narkewa (VOC=0(bisa ga umarnin RoHS/REACH)

2. Maganin ciwon kai

Maki na ciwo a masana'antu	Maganin fesa gyare-gyaren
Kayan aikin waje sun lalace kuma sun lalace	Kauri na fim ɗin ya kai 80μm kuma tsufa mai hana ultraviolet
Rufin kayan aiki mai rikitarwa ba shi da daidaito	Shafar electrostatic ta kai ga cikakken rufewar kusurwoyin da ba su da kyau
Gurɓatar fenti na gargajiya yana raguwa	Yawan dawo da foda > 95%

II. Ka'idar Aiki

1. Tsarin shaye-shaye na lantarki da kuma maganin zafi guda biyu

2. Tsarin samar da ƙananan fim:

① Cajin foda → ② shawagi a alkibla → ③ daidaita narkewa → ④ magance haɗin gwiwa → ⑤, yana samar da tsarin ƙwayoyin halitta a rufe

(Hoto: ƙa'idar aiki ta murfin foda na electrostatic (shafa foda mai caji + warkar da zafin jiki mai yawa))

III. Tsarin aikin tsari

Ayyukan da aka daidaita

1. Kafin a fara magani (Kashi 60% na taro)

• Rage kitse (maganin alkaline, 50℃×8min) → wanke ruwa → phosphating (nauyin membrane mai tushen zinc 1.5-3g/㎡) → wanke ruwa mai tsarki → 120℃ bushewa

2. Feshin Electrostatic

• Kayan aiki: bindigar feshi ta lantarki mai ƙarfi mai ƙarfi (ƙarfin fitarwa-70kV)
• Sigogi: matsin lamba na iska 0.5MPa, nisan daga wurin aikin 200-300mm, sarrafa kauri na fim ±10μm

3. Gyara da yin burodi

• lanƙwasa zafin jiki :
Zafin cikin gida (minti 10) → 180°C (minti 20) → Kare zafi (minti 10) → Sanyaya

4. Ka'idojin duba inganci

• Mannewa: hanyar karce (ASTM D3359) 0 wanda ya cancanta
• Kauri: ma'aunin kauri na eddy current ≥60μm

IV. Kwatanta da sauran tsare-tsare

Halaye	Fesa robobi	Fesa fenti	Na'urar lantarki (Electrogalvanizing)
Rayuwar hana lalata	Shekaru 5-8 (a waje)	Shekaru 1-3	Shekaru 3-5 (babu buƙatar taimako)
Kare Muhalli	Babu hayakin VOC	Rushewar sinadaran Benzene	ruwan sharar chromate
Zaɓin launi	Fiye da launuka 2000 na Pantone	Fiye da launuka 500	Farin azurfa/mai launin shuɗi kawai
Rufin kusurwa	⼞95%	70-85%
Haɗaɗɗen farashi	¥25-50/㎡	¥15-30/㎡	¥20-40/㎡

Misali na yau da kullun:

Kabad ɗin sadarwa (roba mai feshi): An zaɓi launin toka na RAL7035, kauri na fim ɗin shine 80μm, kuma gwajin fesa gishirin yana aiki awanni 480 ba tare da tsatsa ba

Sassan fenti masu tsari iri ɗaya: kumfa na awanni 200, farashi ƙasa da 30%, amma rayuwa ta takaice 60%

V. Shawarar yanayin aikace-aikace

• Yanayin da aka fi so:

✅ Kayan aiki na waje (akwatin rarraba wutar lantarki/kabad 5G)
✅ Kayan aikin gida (fannin firiji/ƙafafun sanyaya iska)
✅ Sassan tsarin launi masu launi (shelfs/kayan aikin nunin faifai)

• Yi amfani da yanayi cikin taka tsantsan:

❌ >200℃ yanayin zafi mai yawa (Rawaya daga resin epoxy)
❌ Yanayin nutsewa mai ƙarfi na acid (juriyar acid da alkali ta fi rauni fiye da electrophoresis)

Kammalawa: Rufin feshi ya zama mizani na zinare na kariyar tsatsa a farantin ƙarfe tare da fa'idodi uku na kariyar muhalli, ado da rufewa. Mingli Metal yana da layin feshi ta atomatik da tsarin canza launi mai sauri (), wanda zai iya samar wa kamfanoni mafita ɗaya tilo daga zaɓe zuwa yawan samarwa.

Ƙara: ainihin yanayin feshi na filastik tsarin sarkar

Hoto: layin samar da filastik mai feshi ta atomatik (kafin magani → ɗakin lantarki → murhun wuta mai warkarwa)
