PVC Tarpaulin npawt nhpang ni a hpaji masa hte jai lang ai lam hpe sawk sagawn ai lam

PVC tarpaulin gaw aten kadun nta ni, sutdek ni hpe ka-up ai, shinggan de ndau shabra ai lam ni hte kaga bungli ni hta grai lang ai bungli galaw ai arung arai langai rai nga ai. Shi a hkrang gaw, dai arai a ngang grin ai lam, hka n shang hkra galaw lu ai lam, grup yin hpe galai shai lu ai lam ni hpe hkrak sha hkra machyi shangun ai. Ndai laika buk hta PVC tarpaulin a hkrang masa hte hpaji masa akyu ni hpe, arung arai ni a npawt nhpang, n-gun lapran na hkrang masa, bungli galaw ai atsam marai ni, hte laksan jai lang ai lam ni a ningmu ni hku nna, hkrang shapraw ai hku nna sang lang dan da ai.

 

1. PVC Tarpaulin a madung arung arai ni

PVC (polyvinyl chloride) tarpaulin a madung npawt nhpang arung arai gaw polyvinyl chloride resin rai nna, dai hpe plastic, n-gun n rawng ai, UV n-gun rawng ai zawn re ai n-gun rawng ai arung arai ni hpe jat bang nna, n-gun rawng ai polymer arung arai langai byin tai wa hkra galaw ai. Plasticizers (phthalates zawn re ai) ni gaw, dai arai a n-gun hpe jat ya ai majaw, n-gun n law ai aten hta pyi, n-gun n rawng hkra galaw lu ai. Calcium zinc (sh) organotin zawn re ai n-gun ja ai tsi ni gaw, katsi ai hpe ninghkap lu ai atsam hte asak kaba wa ai hpe ninghkap lu ai atsam hpe jat ya nna, tarpaulin a prat hpe galu shangun ai. Nkau high-end arung arai ni hta mung, wan n-gun shayawm ai (sh) ana zinli n-gun shayawm ai arung arai ni hpe bang nna, jai lang ra ai lam ni hpe hkan sa lu ai.

 

II. Multi-layer law law lawm ai hkrang shapraw ai npawt tara ni

Dai ni na aten na PVC tarpaulin ni gaw, n bung ai bungli galaw ai layer ni hpe galaw na matu, n bung ai layer law law hpe shapraw ai (sh) coating composite ladat hpe jai lang ma ai:

Base layer (support layer): N-gun ja ai-polyester n-gang (PET zawn re ai) shing nrai, glass n-gang mesh hte galaw da ai rai nna, tarpaulin a n-gun yawng hpe n-gun jaw ya nna, shinggan n-gun ni a majaw byin wa ai n-gun n-gun hpe pat shingdang ya ai.

Lapran na bungli galaw ai layer: Madung hku nna PVC film hte galaw da ai rai nna, npawt nhpang layer de hot-melt bonding (sh) calendaring hku nna matut mahkai da ai. Ndai layer gaw tarpaulin a core bungli hpe dawdan ya ai. Ga shadawn, PVC a n-gun hpe gram lajang ai gaw hka n shang hkra galaw lu ai (ga shadawn, IPX7 du hkra), carbon black particles ni hpe jat bang ai gaw UV hpe grai hkam sharang lu ai (UPF manu ni 50+ hta jan ai).

Ntsa lam hpe gram lajang ai layer: Nkau mi hpe polyurethane (PU) (sh) acrylic varnish hte ka-up nna, n-gun n rawng ai hte n-gun n rawng ai makawp maga ai film hpe galaw ya ai, dai sha n-ga, npu na n-gun hpe mung grau kaja hkra galaw ya ai majaw, nhprang wan hte marang hka n-gun n rawng hkra galaw ya ai.

 

III. Madung magam bungli arawn alai ni hpe hkrang shapraw ai lam

PVC tarpaulin ni a hkrang masa gaw shanhte a tengman ai bungli galaw ai lam hpe hkrak hkra machyi shangun ai:

Hka n shang hkra galaw lu ai: Matut manoi, n-gun ja ai PVC shingnip (0.1-0.5mm galu ai) gaw hka hpe tsep kawp n shang lu hkra galaw ya ai. Seams ni hpe high-frequency welding (sh) sealing tape hte n-gun shaja da ai majaw, aten galu marang hte hka lim ai aten hta pyi, hka n pru hkra galaw lu ai.

Nbung laru hpe ninghkap lu ai atsam: UV absorbers ni a ntsa e maren mara garan ginhka ai lam, anti-aging layer a synergistic effect hte hpawn, -30℃kaw nna 70℃du hkra nbung laru hta ngang grin ai hku galaw lu ai, shinggan de 5-10 ning tup galaw lu ai.

Mechanical Strength: Warp hte weft tensile n-gun gaw madung hku nna 200N/5cm (DIN madang hku) jan ai, tear n-gun gaw 150N jan ai majaw nbung laru kaba hte hka lim ai zawn re ai n-gun ja ai lit ni hpe hkam sharang lu ai.

 

IV. Laksan jai lang ai mabyin masa ni hte hkrang masa hte htuk manu ai lam

PVC tarpaulin npawt nhpang ni hpe jai lang ai lam amyu myu gaw, n bung ai ra sharawng ai lam ni hpe tawn da ya ai:

Jahtum na aten na matu galaw da ai nta ni (tsin-yam tsindam hkye mawai sum ni zawn re ai ni): N-gun n law ai hte lawan ai hku gawgap na hpe ahkyak shatai nna, shanhte gaw nbung n shang hkra galaw da ai, aluminum alloy frame ni hte kata na lining hpe grau kaja hkra n-gun ja hkra galaw na matu, double-layer hpe jai lang ma ai.

Warehouse Covering: Load-bearing hte n-gun n-gun hpe ahkyak shatai nna, n-gun ja ai arung arai ni kaw na n-gun n-htum hkra, npawt nhpang layer hpe steel mesh (sh) Kevlar fiber hte shinggrup da ai.

Advertising Display: Nhtoi hpe n-gun ja hkra shapraw lu na matu hte nsam hpe n-gun ja hkra shakut ai majaw, ntsa kaw na dip shapraw ai layer hpe UV curing hpaji hku nna PVC substrate hte matut da nna, ngang grin ai hte asan sha re ai sumla ni hpe lu la na matu galaw da ai.

 

Daw dan lam

PVC tarpaulin hta npawt nhpang hpaji ningnan ni gaw, shara law law hta jai lang na matu matut nna shadut ya nga ai. Htawm hpang de, grup yin hpe n hkra ai jat bang ai arung arai ni (bio-based plasticizers zawn re ai ni) hte hpaji rawng ai arung arai ni (temperature-sensitive color-galai shai ai coatings zawn re ai ni hpe shapraw ai hte, PVC tarpaulin gaw, bungli galaw lu ai atsam hte, dai ni na aten na engineering ra kadawn ai lam ni hpe jaw ya lu na matu, grau nna rawt jat galu kaba wa na hpe myit mada nga ai.
