Sealant chyam dinglik ai lam hpe sawk sagawn ai

Gawgap, mawdaw, hte hpaga lam ni hta ahkyak ai sealing arung arai langai hku nna, sealants ni a bungli galaw ai lam gaw project a quality hte service prat hpe hkrak hkra hkra machyi shangun ai. Sealant kam hpa mai ai lam hpe kam mai hkra, shanhte gaw hkrang shapraw ai chyam dinglik ai lam hku nna, hkum tsup ai hku jep joi ai lam galaw ra ai.

1. Sample hkyen lajang ai lam hte shawng tsi lajang ai lam

Chyam dinglik ai lam garai n galaw shi yang, sealant sample ni hpe masat da ai masat masa ni hte maren hkyen lajang ra ai. Ndai hta, laksan hku nna, substrate hpe hkyen lajang ai (ga shadawn, jasan jaseng ai hte hpraw hkra galaw ai), adhesive hpe kayau kaya galaw ai (dai lahkawng hpe hkrak ai shadawn shadang hta maren mara kayau ra ai), hte forming (ga shadawn, injection molding (sh) coating) ni lawm ai. Sample ni hpe masat da ai aten (ga shadawn, hkying hkum 24) laman, masat da ai makau grup yin (katsi ai 23±2℃, hka lim ai 50±5% RH) hta tsi lajang ra ai, dai hku nna, teng sha jai lang ai masa hpe shingdaw yu ra ai.

2. Hkum hkrang arung arai ni hpe chyam dinglik ai lam

Hardness Testing: A Shore Durometer hpe lang nna, hkam kaja wa ai sealant a n-gun hte n-gun n-gun hpe shadawn nna, jai lang ra ai lam ni hpe hkan sa ai hpe kam mai ai.

Tensile Adhesion: Tensile chyam dinglik jak hpe lang nna, sealant hte substrate lapran daw garan ai shaloi, n-gun n-gun hte galu kaba ai lam hpe shadawn nna, shi a shara htawt sit ai lam hpe ninghkap lu ai atsam hpe jep yu ai.

Elastic Recovery Rate: Ndai gaw colloid langai hpe n-gun shayawm ngut ai hpang n-gun yawm mat ai kaw na bai hkam kaja wa lu ai atsam hpe shadawn ai, aten galu-lang lang ai shaloi shi a hkam sharang lu ai atsam hpe madun dan ai.

III. Chemical hte nbung laru chyam dinglik ai lam

Ndai chyam dinglik ai lam ni hta, nbung katsi ai hpe hkam sharang lu ai (hpyen n-gun kaba/n-gun n law ai hpe tawn da ngut ai hpang bungli galaw ai lam galai shai wa ai), hka hpe hkam sharang lu ai (hka de lup bang ngut ai hpang n-gun n-gun hpe n-gun n-gun n-nga ai), UV asak kaba wa ai hpe chyam dinglik ai (hpang aten galu-nhtoi htoi ai majaw byin pru wa ai yellowing (sh) chalking hpe shingdaw ai) ni lawm ai. Nkau laksan jai lang ai lam ni hta mung, sau hte hka ja ai n-gun hpe ninghkap lu ai atsam zawn re ai, chemical stability hpe chyam dinglik ra ai.

IV. Hkrit tsang hpa arung arai ni hte grup yin masat kumla ni

Seng ang ai tara ni (GB 18583 zawn re ai) hte maren, grup yin ra kadawn ai lam ni hpe hkan sa lu na matu, n-gun ja ai n-gun dat (VOC) ni, n-gun ja ai n-gun dat ni, formaldehyde n-gun dat ni hpe chyam dinglik ai.

V. Mahtai hpe lachyum shaleng nna shiga jaw ai lam

Chyam dinglik ai lam yawng hpe mungdan madang (GB/T 14683 hte ASTM C920 zawn re ai) shing nrai, hpaga lam madang hte shingdaw ra ai. Chyam dinglik ladat, masa lam ni, dawdan ai lam ni hpe ka da ai tara shang jahpan hpe shapraw nna, arung arai ni hpe lata la na matu hpaji masa hku nna npawt nhpang jaw na re.

Ndai madang masat da ai ladat hku nna, sealant a bungli hpe hkrang shapraw ai hku jep joi lu nna, yak hkak ai makau grup yin ni hta aten galu-kam mai ai lam hpe kam mai ai.
