Rubber seal amyu myu gaw, bungli galaw ai shara hte shani shagu na sak hkrung lam hta hka n pru hkra pat shingdang na matu madung daw ni rai nga ai. Rubber arung arai amyu myu a bungli galaw ai lam n bung ai hpe akyu jashawn nna, mawdaw, tsi tsi ai lam, tsi hpaji zawn re ai ginra law law hta yak hkak ai bungli masa ni hpe hkrak hkrak hkan sa lu nna, jak rung ni hpe ngang grin hkra galaw lu na matu hte shim lum ai hte pat da ai hkrang masa ni hpe galaw lu na matu ahkyak ai madi shadaw lam tai wa ai. Shanhte a jai lang ai lam ni a galu kaba ai lam hte hpaji masa hpe hkrak hkrak galai shai ai lam gaw, rubber material engineering a manu dan ai lam hpe madun dan nga ai.
Rubber seal ni gaw kaji ai zawn rai tim, bungli amyu myu hta "leak-proof guardians" hku nna ahkyak ai lit hpe gun hpai nga ai. Shanhte a jai lang ai lam a sung htum ai lam gaw, arung arai atsam marai ni a bung ai madang hte grai ni htep ai:
Mawdaw hpaga lam: Sau-hkap la lu ai Seal ni a "Power Guardian"
Mawdaw engine hte gearbox zawn re ai madung daw ni hta, nitrile rubber (NBR) seal ni gaw, grai kaja ai sau hpe ninghkap lu ai atsam (mineral sau hta n-gun n-gun jat ai lam < 10%) hte jak n-gun atsam ni hte, sau hte sau chya ai sau circuit ni a matu "hkap pat da ai pat shingdang ai lam" langai zawn galaw ya nga ai. Ga shadawn, engine sau shingnip ni gaw, nitrile rubber a elastic deformation hku nna, n-gun ja ai-n-gun ja ai engine sau hpe aten galu hkam sharang lu ai majaw, n-gun n-gun n-gun n-nga ai sha bungli galaw lu ai. Transmission seal gaw shi a wear-resistant hte tear-resistant atsam ni hpe kam hpa nna, lawan ai jak rung shamu shamawt ai aten hta sealing kam hpa mai ai lam hpe matut manoi tawn da lu ai, mawdaw n-gun atsam system hpe hkying hkum hkying hkum law law tup ngang grin ai magam bungli hpe lu la na matu karum ya ai.
Tsi hpaji: Biocompatible "Hkamja lam makawp maga lam"
Tsi mawan ni hta n-gun n rawng ai hte n-gun n rawng ai ra kadawn ai lam ni a majaw, silicone rubber (VMQ) seal ni hpe grau ra sharawng ai. Ndai zawn re ai seal gaw USP Class VI biocompatibility masat masa hpe lai sai rai nna, shinggyim hkum hkrang na ntsin (sh) tsi mawan ni hte hkrak matut mahkai lu ai. Infusion set, ventilator, artificial organs zawn re ai jak ni hta, gas-liquid hpe pat da lu ai sha n-ga, dai arai hte shinggyim hkum hkrang lapran na ningdang kau ai lam hpe mung koi lu ai. Ga shadawn, tsi tsi ai hka htung ni a pat da ai arung arai ni gaw, silicone rubber a san seng ai lam hte ana zinli n kap hkra galaw lu ai atsam grai law ai (-katsi ai nbung n-gun n rawng ai hpe hkam sharang lu ai), tsi tsi ai lam hta shim lum ai hte ana zinli n kap hkra galaw ya lu ai.
Chemical hpaga lam: Grai n-gun ja ai makau grup yin hta "N-gun ja ai hpe ninghkap lu ai Pioneer"
N-gun ja ai acid, n-gun ja ai alkali, n-gun ja ai oxidants zawn re ai grai sawng ai media ni a man hta, fluororubber (FKM) seal ni gaw "hpyen n-gun hpe ninghkap lu ai ningshawng" a n-gun hpe madun dan nga ai. Chemical n-gun rawng ai hka htung ni hte sau htu ai hka htung ni zawn re ai mabyin masa ni hta, fluororubber gaw 260℃hte 98% n-gun rawng ai sulfuric acid hta aten galu-n-gun rawng ai hka lim ai lam hpe hkam sharang lu ai. 20% hta npu na compression set hte, n-gun kaba ai-hpring ai hte grai n-gun ja ai masa ni hta aten galu sealing stress hpe hkam la lu nna, chemical system hpe n-htum hkra, n hkrat sum hkra galaw ya lu ai. Chemical hpaga lam hpe shim lum ai hte hkrak hkra galaw shapraw lu na matu madung madi shadaw ai lam rai nga ai.
Shani shagu lang ai arung arai ni: Hka n shang ai hte ga nhpu n shang ai "Life Assistant" langai mi.
Nta kata na kashin jak ni hta hka shingnip ni kaw nna, wan jak ni hta ga nhpu shingnip ni du hkra, ethylene propylene diene monomer (EPDM) hte chloroprene rubber (CR) shingnip ni hpe shani shagu na sak hkrung lam hta sung sung htuk bang da sai. EPDM seal ni gaw nbung laru hpe grai hkam sharang lu ai majaw (shinggan ozone aging life > 5 ning) hkuwawt chyinghka ni hpe pat da ai strips ni hte nbung laru pipeline ni hpe pat da na matu, masha law malawng lata la ai lam langai byin wa sai. CR seal ni gaw, wan n-gun hpe n-hkap la lu ai hte n-gun n-gun hpe n-hkap la lu ai atsam ni hte, wan jak ni a shaft seal ni de nhprang wan hte n-gun n-gun ni hpe atsawm sha pat shingdang ya lu ai majaw, jak a prat hpe galu kaba shangun lu ai.
Ndai rubber seal ni gaw, arung arai ni a arawn alai ni hpe madung tawn nna, shara ra kadawn ai lam ni hpe madung tawn nna, ginra amyu myu hta "closed defense line" hpe gawgap ya ai. Mawdaw n-gun hpe ngang grin ai hku htawt sit ai kaw nna, tsi tsi ai lam hte hkamja lam hpe shim lum hkra galaw ai lam de, dai hpang, tsi mawan galaw shapraw ai hta hkrit tsang hpa hpe makawp maga ai lam hte hkang zing ai lam ni du hkra, shanhte a galu kaba ai jai lang ai lam gaw, rubber material engineering a hpaji masa awng dang ai lam ni hpe madun dan ai sha n-ga, n mu lu ai npawt nhpang nlung mung tai wa ai.
