PTFE High Temperature Tape hmanga Curved Surface-a Lamination Effect tihchangtlun dan

PTFE high-temperature fabrics siamtu professional a nih angin Jiangsu Aokai New Materials hian practical solutions a rawn share sak che a ni.

PTFE high temperature tape hi bubble leh edge warping awm lovin curved leh irregular surface-a nghet taka hman tur chuan standardized operation process a pawimawh a, chutah chuan substrate pretreatment uluk tak, professional application skills leh auxiliary measures dik tak te pawh a tel a ni. Chumi zingah chuan substrate pretreatment hi step pawimawh ber a ni a, hei hian final sticking effect 70% vel a tichiang a ni.

1. Substrate siam that tawk

●  Thianghlimna : Bonding surface chu anhydrous ethanol emaw acetone emaw hmangin phihfai vek la, oil stain, leivut leh bawlhhlawh te chu paih chhuak rawh. Gasoline leh solvent dang residual grease hnutchhiah thinte chu pumpelh rawh.

●  Sanding dik tak : A hmun hrual lutuk chu 240-320 grit fine sandpaper hmangin zawi zawiin polish la, micro rough texture siam la, chutiang chuan contact area leh mechanical adhesion a tipung ang. Polishing zawhah leivut zawng zawng chu uluk takin tifai vek ang che.

●  Environment & temperature control : Construction environment chu a vawt leh leivut awm lohnaah dah la, hnathawhna temperature chu 15°C atanga 40°C inkar a ni. Temperature 10°C hnuai lam chuan initial tackiness nasa takin a tihziaawm ang a, adhesion tha lo tak a siam bawk ang.

2. Application Techniques dik tak siam

●  Tape tling thlang rawh : Tape, adhesion sang leh ductility sang tak neia marked te chu dah pawimawh ber la, chu chu curved surface-ah a fit tha zawk hle. 260°C thlenga hun rei tak service theihna tur silicone pressure-sensitive adhesive tape thlang rawh. PTFE material-a surface energy a hniam avangin tape pangngai chu nghet taka stick harsa tak a ni. Chemical etched emaw plasma-treated adhesive side nei tape thlan hi a tha hle. Treated surface-a active group-te hian bonding force chak zawk an siam thei a, edge lifting pawh a titawp thei bawk.

●  Tape chu preheat (optional) : Tape chu hair dryer hmangin 60°C hnuaiah rei vak lo preheat la, adhesive initial viscosity leh fluidity a ti tha ang a, uneven leh curved surface-ah wetting effect tha zawk a nei ang.

●  Segmented sticking method : Release liner pumpui chu vawi khatah phelh loh tur. A tawp pakhat emaw, a lai lam point emaw chu siam that hmasa la, chutah chuan liner chu step khat hnu step khatin peel la, tape section chu section khatin (segment khatah 5-10cm) surface radian-ah attach rawh.

●  Air evacuation method : Silicone roller emaw scraper emaw hmangin a lai atanga a sir lehlamah a inang tlangin press la, bonded area atanga unbonded area ah press la, boruak tang chu squeeze chhuak vek rawh.

3. Practical Auxiliary Skills neih theihna tur

●  Thermal shaping & compaction : Preliminary pasting hnuah tape chu hot air gun hmangin a rualin lum la, adhesive chu a activate ang a, a fluidity a ti sang ang a, full surface wetting a awm ang. Roll la, a lum laiin nghet takin press la, a bik takin a sir lamah. He step hi 0.18mm aia sang tape thick tan chuan a pawimawh hle.

●  Edge warping kha khauh taka ven : Application laiin tape hi stretch ngai suh, rebound force hi edge lifting chhan ber a nih avangin. Sealing effect tha tak neih theih nan overlapping width 20mm aia tam dah la. Scraper hmangin a sir zawng zawng chu compact nawn leh rawh. Adhesive curing kimchang leh bonding strength tha ber neih theih nan room temperature-ah darkar 24 atanga 48 chhung dah la. Edge firmness sang zawk atan chuan reinforcement atan high temperature resistant silicone sealant tlem te te hmang la.

●  Remedy solution : A hnawih hnua edge warping tlem a awm chuan warped part chu hot air gun hmangin local-ah lum la, repair turin tight takin re-roll leh rawh.
