FRP (fiberglass hte n-gun ja ai plastic) lamu nhtoi ni hpe gara hku ninghkap lu ai kun?

FRP (hpun n-gang hte n-gun ja ai plastic)nhtoi-shalai ya ai panel ni gaw madung hku nna UV nhtoi, acid hte alkali n-gun, laksan nbung laru ni hpe gram lajang ai arung arai ni hpe gram lajang ai hte yaw shada ai hkrang shapraw ai lam ni hku nna hparan ya ai. Madung manghkang gaw makawp maga ai lam, nhtoi hpe lai di lu ai lam, ngang grin ai lam lapran hta rap ra ai lam hpe tam ai hta rai nga ai.

1. UV makawp maga ai lam: Ntsa ntsa makawp maga ai + Substrate Nbung laru hpe ninghkap lu ai - Double Insurance

UV radiation a majaw board ni hpraw mat nna, n-gun n rawng mat nna, nhtoi hpe n shapraw lu ai. Makawp maga na matu ahkyak ai lam gaw "npu na pat shingdang ai lam" hte "npu na n-gun hpe ninghkap ai-aging" lahkawng yan hta nga ai.

Surface UV-resistant Coating: UV makawp maga ai n-gun grai law ai layer (PMMA ngu ai hpe lang ai) hpe board ntsa de co-extrude galaw nna, 50-100μm lapran na n-gun hpe hkang lu ai. Ndai layer gaw UV nhtoi 90% jan hpe hkrak sha n-gun jaw lu ai (sh) hkap la lu ai majaw, kata na n-gun hpe hkra machyi hkra pat shingdang lu ai.

Nbung laru-hkap la lu ai Resin Substrate: Nbung laru-hkap la lu ai unsaturated polyester resin hpe shinggyim masha ni lang ai resin a malai lang ai majaw, npawt kaw na UV hpe ninghkap lu ai atsam hpe grau kaja hkra galaw ya lu nna, aten galu-hkap la ngut ai hpang hkrat sum ai lam hte n-gun yawm mat ai lam hpe shayawm ya lu ai.

Hpaji rawng ai hkrang shapraw ai lam: Coating a n-gun hpe hkrak hkrak hkang ra ai. Grai n-gun n rawng ai layer gaw n law htum makawp maga lam jaw ya nna, grai n-gun ja ai layer gaw nhtoi hpe shayawm ya ai. 50-100μm galu ai gaw makawp maga lam hte nhtoi hpe htawt sit ra ai lam lahkawng yan hpe myit dik shangun ai.

2. Acid hte Alkali n-gun hpe gasat ai: Resin hpe lata ai + Structural hpe garan ginhka ai

Acidic hte alkaline makau grup yin ni gaw board a ntsa hpe n-gun n rawng hkra galaw nna, kata de shang wa ai majaw, delamination byin wa chye ai. Madung gaw "material corrosion hpe ninghkap lu ai" hte "hkum hkrang hpe garan ginhka lu ai" hku nna lahkawng lang makawp maga ai lam re.

Ra ai hku Resin Matching galaw ai: Resin amyu hpe n-gun n-gun hte maren lata la u. N-gun n rawng ai n-gun n rawng ai a matu (ga shadawn, malu masha galaw ai htingnu ni hta), phthalic resin hpe lang u; n-gun ja ai n-gun n-gun n-gun n-nga ai (ga shadawn, wan n-gun n-gun n-rawng ai bungli galaw ai shara ni hte tsi rung ni hta) a matu, isophthalic (sh) vinyl ester resin hpe lang u. Hpang jahtum na gaw acid hte alkali hpe 3-5 lang ninghkap lu ai atsam hpe jat ya lu ai.

Dense Fiberglass Layer Protection: Dai kata hta alkali-n ​​lawm ai fiberglass hpun palawng hpe lang ai, dai gaw shingra tara hku nna chemical hpe n-gun n rawng ai hte n-gun ja ai shingdu shingna hpe shabyin ya ai majaw, acid hte alkali hka ni hpe resin kata de n shang hkra pat shingdang ya nna, n-gun n rawng ai hte n-gun n rawng ai hpe koi ya ai.

Smooth Surface Treatment: Board a ntsa hpe n-gun n rawng ai hte n bung ai hpe shayawm na matu polished galaw ai, acid hte alkali ntsin ni a n-gun rawng ai shara hpe shayawm ya ai, dai sha n-ga, san seng ai lam hpe mung loi ai hku galaw ya ai hte n-gun rawng ai n-gun ni hpe mung shayawm ya ai.
