PVC galu kaba ai hpun nba hpe galaw ai ladat hpe sawk sagawn ai lam
PVC stretch fabric ngu ai grai n-gun ja ai hte ngang grin ai synthetic material rai nna, shinggan na arung arai ni, sum ni, ndau shana ai arung arai ni, tsi tsi ai lam hta makawp maga ai arung arai ni hta grai lang ma ai. Shi a hkrang shapraw ai lam gaw, dai arai a hkum hkrang atsam marai ni hte magam bungli prat hpe hkrak hkra hkra machyi shangun ai majaw, core process flow hpe chye na na matu ahkyak nga ai.
PVC n-gun ja ai hpun palawng hpe galaw ai ladat gaw, raw material hpe kayau kaya galaw ai, extrusion calendering galaw ai, n-gun ja ai hte orientation galaw ai, hte post-hpang jahtum galaw ai lam ni rai nga ai. Langai, polyvinyl chloride (PVC) resin hpe plasticizer, stabilizer, sau zawn re ai jat bang ai arung arai ni hte htap htuk ai shadawn shadang hku kayau nna, lawan ai-blender hta maren mara garan nna, laksan n-gun rawng ai paste byin tai wa hkra galaw ai. Ndai madang hta additives ni hpe lata ai lam gaw, dai arai a n-gun atsam, nbung laru hpe ninghkap lu ai atsam, UV hpe ninghkap lu ai atsam ni hpe hkrak hkra hkra machyi shangun ai.
Dai hpang, dai hka hpe extruder de shang nna, dai kaw na nbung katsi ai (160-180℃daram) hta hka ja nna, T-die hku nna sheet langai mi de shapraw dat ai. Dai hpang, dai sheet hpe roller ni hte calender galaw nna, n-gun n-gun hte ntsa n-gun hpe hkang lu ai. Calendering temperature hpe hkrak hkrak hkang ra ai, dai gaw grai katsi ai majaw (sh) n-gun n rawng ai majaw byin pru wa ai kata lam n-gun n rawng ai majaw, arung arai ni hten za mat na hpe koi lu na matu re.
Hpa majaw nga yang, n-gun ja ai PVC n-gun ja ai hpun palawng hpe jaw ya ai core process gaw, n-gun ja ai hte orientation galaw ai lam rai nga ai. Dai laika hpe uniaxial (sh) biaxial hku n-gun jat ai jak hta n-gun n-jaw shi yang, shawng nnan katsi shangun ai (ga shadawn 80-120℃). Dai stretch ratio gaw 2-5 lang daram rai nna, molecular chain ni hpe n-gun atsam a maga de shingdaw nna, dai arai a galu kaba wa ai lam hte hkam sharang lu ai atsam hpe grai shatsaw ya lu ai. Nkau high-end arung arai ni gaw, jak rung a n-gun hpe grau kaja hkra galaw na matu, sequential stretching hpaji hpe jai lang ma ai.
Hpang jahtum, gang je kau ai nba gaw, katsi ai hte katsi ai hpe hkrum sha ai. Heat setting hta aten kadun laman hta nbung katsi ai (100-130℃daram) hpe n-gun dat nna, molecular structure hpe ngang grin hkra galaw nna, ngam nga ai n-gun hpe yeng seng kau lu ai. Dimensional hpe n-gun n rawng hkra nbung (sh) hka hte katsi shangun ai. Nkau mi arung arai ni hta mung, UV hpe n-gun n jaw lu ai coatings (sh) wan n-gun hpe n-gun n jaw lu ai baw ni zawn re ai ntsa lam hpe gram lajang ra ai majaw, bungli grau kaja hkra galaw ra ai.
PVC stretch fabric a matu molding galaw ai ladat gaw, nbung katsi ai, lawan ai, hte n-gun n-gun hpe grai sadi maja let hkang ra ai. Gara lahkam hta raitim, n tara ai lam ni gaw, n kaja ai arung arai galaw ai lam hpe byin shangun chye ai. Online hku nna yu reng ai lam hte tinang hkrai hkang ai lam ni hpe hpaw hpang wa ai zawn re ai hpaji masa rawt jat wa ai lam ni gaw, dai ni na aten na ladat ni hpe grau nna akyu rawng ai hte grup yin hpe makawp maga ai lam de woi sa wa nga ai, npu na application ni a matu grau kaja ai arung arai hparan ladat ni hpe jaw ya nga ai.
