Chozimitsira Moto Cylinder Inner Thermoplastic Coating

Zozimitsa moto nthawi zambiri zimapangidwa ndi chitsulo, monga chitsulo kapena aluminiyamu, ndipo amapangidwa kuti azikhala ndi chozimitsa moto chomwe chimagwiritsidwa ntchito kuzimitsa moto. Komabe, zozimitsira moto zina zimatha kukhala ndi mkati zokutira thermoplastic, yomwe imagwiritsidwa ntchito mkati mwa silinda kuti iteteze ku dzimbiri komanso kupititsa patsogolo ntchito yozimitsa.

Chophimba cha thermoplastic chomwe chimagwiritsidwa ntchito muzitsulo zozimitsira moto nthawi zambiri chimakhala polyethylene polima kapena nayiloni. Zidazi zimasankhidwa chifukwa chokhalitsa, kukana mankhwala, komanso kupirira kutentha kwambiri. Chophimbacho chimagwiritsidwa ntchito mkati mwa silinda pogwiritsa ntchito njira yotchedwa rotational molding, kumene kupaka ufa kumatenthedwa ndikuzungulira mkati mwa silinda mpaka kusungunuka ndi kupanga yunifolomu wosanjikiza.

Kugwiritsa ntchito zokutira zamkati za thermoplastic mu masilinda ozimitsa moto kungapereke mapindu angapo. Choyamba, zimathandiza kuteteza silinda ku dzimbiri, zomwe zingayambitsidwe ndi chozimitsa kapena kukhudzana ndi chinyezi. Kuwonongeka kumatha kufooketsa silinda ndikuchepetsa mphamvu yake yokhala ndi chozimitsa bwino, zomwe zingasokoneze kugwira ntchito kwake pakagwa mwadzidzidzi.

Kachiwiri, zokutira za thermoplastic zitha kupititsa patsogolo magwiridwe antchito a chozimitsa. Mwachitsanzo, mu zozimitsa moto za carbon dioxide (CO2), chophimbacho chingalepheretse CO2 kuti isagwirizane ndi chitsulo cha silinda, zomwe zingapangitse kuti silinda ifooke kapena kuphulika. Kuonjezera apo, zokutirazi zingathandize kuchepetsa CO2 yomwe imatuluka mu silinda pamene ikugwiritsidwa ntchito, zomwe zingathe kupititsa patsogolo mphamvu ya chozimitsira moto.

Komabe, pali zodetsa nkhawa za chitetezo cha zokutira za thermoplastic mu masilinda ozimitsa moto. Ngati chophimbacho sichinagwiritsidwe bwino kapena chawonongeka, chikhoza kusenda kapena kuphulika, chomwe chingawononge chozimitsacho ndikuchipangitsa kuti chiwonongeke. Kuonjezera apo, ngati chophimbacho chikatenthedwa ndi kutentha kapena moto, chimatha kutulutsa utsi wapoizoni, womwe ukhoza kuvulaza anthu ndi chilengedwe.

Kuonetsetsa chitetezo ndi mphamvu ya zozimitsira moto ndi zokutira mkati thermoplastic, m'pofunika kutsata ndondomeko yoyenera yosamalira ndi kuyendera. Masilinda ayenera kuyang'aniridwa nthawi zonse kuti aone ngati akuwonongeka kapena akudziwira, ndipo zolakwika zilizonse ziyenera kuthetsedwa mwamsanga. Kuonjezera apo, zozimitsa moto ziyenera kugwiritsidwa ntchito motsatira malangizo a wopanga ndipo ziyenera kusungidwa ndi kunyamulidwa bwino kuti zisawonongeke kuti zisawonongeke.

Pomaliza, kugwiritsa ntchito zokutira zamkati za thermoplastic mu masilinda ozimitsa moto kungapereke maubwino angapo, monga kuteteza ku dzimbiri komanso kukonza magwiridwe antchito a chozimitsa moto. Komabe, pali zodetsa nkhawa za chitetezo cha zokutira izi, makamaka ngati zawonongeka kapena zitakhala ndi kutentha kwambiri. Ndikofunika kutsata njira zoyendetsera bwino ndikuwunika kuti zitsimikizire chitetezo ndi mphamvu zamasilinda ozimitsa moto okhala ndi zokutira zamkati za thermoplastic.

PECOAT® Fire Extinguisher Cylinder Inner Thermoplastic Coating ndi polima yopangidwa ndi polyolefin, yopangidwa kuti igwiritsidwe ntchito pozungulira pamasilinda achitsulo kuti ipatse zokutira zoteteza zolimbana ndi malo okhala ndi madzi, kuphatikiza AFFF yotulutsa thovu komanso imalimbana mpaka 30% Antifreeze ( ethylene glycol). Mukagwiritsidwa ntchito moyenera, zokutirazo zimapereka zomatira zabwino kwambiri popanda kufunikira kwa chomatira chapadera ndipo zimatha kupirira kutentha kwapang'onopang'ono kapena panjinga pakati pa -40 ° C ndi +65 ° C.
