PTFE Emulsion Impregnated Fiberglass Cloth chu Industrial Production Process kimchang tak a ni

PTFE high-temperature fabric siamtu Jiangsu Aokai New Materials chuan a kalphung kimchang a kalpui che a ni.

PTFE high-temperature fabric, chemical-a polytetrafluoroethylene (PTFE) coated fiberglass cloth tia hriat chu polymer composite material langsar tak a ni. A siam dan hi coating process awlsam tak a ni lo va, thermal leh chemical treatment system thiam tak a ni. PTFE high-temperature fabric quality sang tak siam tur chuan stage pali hmanga tih dan khauh tak a ngai a, chungte chu base fabric buatsaih, impregnation solution buatsaih, core impregnation leh sintering, leh post-treatment te an ni.

Stage 1: Base Fabric siam hmasak ber

He stage hian PTFE fabric hnuhnung ber mechanical strength leh structural integrity a tichiang a ni.

Thermal Cleaning (Dewaxing) PTFE puan hrualna atana hman fiberglass yarn hian siam chhuah laiin organic sizing agents a pai a. A chhuah loh chuan heng agents te hian a hnu lama PTFE coatings te adhesion nasa takin a tikhawlo thin. Chuvangin, a hmasa ber atan chuan base fabric chu fiberglass substrate thianghlimna tur atan rang taka dewaxing atan high-temperature furnace (approx. 350°C)-ah dah a ni.

Surface Modification Fiberglass leh PTFE coating resin inkara bonding strength tihchangtlun nan base fabric chu silane coupling agent hmangin an treat a. He step hian interlaminar peel strength nasa takin a tichak a, finished product-a delamination emaw coating peeling emaw a veng bawk.

Stage 2: PTFE Impregnation Emulsion siam dan

Tun dinhmunah hian final fabric-a physical leh chemical property hi a tam zawkin a innghat a ni.

· Emulsion Mixing A bulpui ber raw material chu PTFE dispersion concentrated a ni . A hman dan tur hrang hrang — food baking fabrics-a non-stick performance sang tak emaw, release fabrics-a wear resistance sang emaw ang chi — angin filler leh additives te chu emulsion-ah hian chiang takin an dah tel a ni. Formulated impregnation solution hi PTFE fabric siam zawh tawh grade tihfiah nan a pawimawh hle.

Stage 3: Core Impregnation leh Sintering tih a ni

Hei hi PTFE fabric-a a performance danglam bik pe theitu key process a ni a, a tlangpuiin cycle repeated a awm thin.

Multiple Impregnations Constant tension control hnuaiah chuan pretreated base fabric chu PTFE emulsion-a khat dip tank-ah a kal leh fo thin. Thickness leh density duhthusam neih theih nan production line chuan cyclic process a hmang a: impregnation → drying → sintering . Cycle tin hian dik takin coating weight a tisang thin.

Drying Impregnated semi-finished fabric chu temperature hniam oven (approx. 100°C) kal tlangin zawi zawiin tui a paih chhuak thin. Hetiang dinhmuna control dik loh hian sintering laiin awlsam takin bubble emaw pinhole emaw a siam a, insulation performance nasa takin a tichhe thin.

High-Temperature Sintering Hei hi thil siamna kawng bulpui ber a ni. Wet coating hi 380°C vel ah sintered a ni a, PTFE particle te chu a hmin kim thei a, a luang chhuak thei a, dense protective film a siam a ni. PTFE fabric hian 260°C-a hun rei tak service a tuar theihna hi he step-a polymer chain recrystallization atanga lo chhuak a ni. Fabric sinter kim lo chu a chhe thei a, non-stick property a hloh fo bawk.

Stage 4: Enkawl hnu leh thil siam zawh tawh enfiah

Sintering hnuah chuan fabric chu finishing process dang a tawk leh thin.

Hot-Press Setting leh Surface Treatment PTFE puan sang tak tak (conveyor belt atana hman ang chi) te chu hot rollers hmangin calender-in a chunglam a flatten a, internal stress a tiziaawm bawk. High-frequency copper-clad laminate-a hman PTFE fabric tan chuan surface roughness tihpun nan special corona treatment hman a ni.

Lamination Process High-end filtration application atan chuan expanded polytetrafluoroethylene (ePTFE) microporous membrane layer te tak te chu a chung lamah laminated a ni a, chu chuan filtration efficiency sang zawk nei composite filter medium a siam a ni.

Aokai New Materials chuan quality endikna khauh tak a kalpui. Final products te hi grammage tester, high-voltage tester leh tensile tester hmanga test a ni. Thil thickness inang, pinhole nei lo, voltage resistance requirement zawm thei chauh chu qualified goods angin chhuah a ni.
