Ishidi Legwebu Lokumuncwa komsindo wePolyurethane

Ishidi Legwebu Lokumuncwa Komsindo Le-Polyurethane Lokulawula Umsindo Wezimboni

Ishidi legwebu le-Topsun lokumunca umsindo le-polyurethane liwumthombo wegwebu ovulekile weseli we-PU oklanyelwe ukuvaleka kwemishini, izindlu zemishini, izingxenye zezimoto ze-NVH, amalayini anomsindo nezinye izinhlelo zokusebenza zezimboni lapho umsindo ovelayo kanye nokuzwakalayo kudinga ukuncishiswa.

Isakhiwo sezimbotshana ezixhumene sivumela umsindo osemoyeni ukuthi ungene kugwebu, lapho ingxenye yamandla e-acoustic ingahlakazwa ngaphakathi kwenethiwekhi yeselula. Igwebu le-Open-cell PU ngakho-ke livame ukusetshenziswa njengolwelwesi lwangaphakathi lwe-acoustic esikhundleni sesithiyo esindayo esivimba umsindo.

Ibanga lamanje lomkhiqizo we-Topsun lihlanganisa ukuminyana okungu-22, 25, 28 kanye no-30 kg/m³. Ibanga lobuchwepheshe elibaluliwe linokucaciswa kokuminyana okungu-23±2 kg/m³ ngomphumela orekhodiwe we-22.42 kg/m³. Amashidi angaphinde asikwe, afakwe elayiniwe, asikwe ngokufa futhi ahlinzekwe nge-adhesive backing ukuze kufakwe okufanele.

Ukumuncwa komsindo PU Foam Izici Key

• Isakhiwo se-Open-cell: ama-pores axhumene avumela umsindo nomoya ukungena esakhiweni segwebu.

• Ukumuncwa komsindo: kusiza ekwehliseni umsindo ovela emoyeni ovela emoyeni nokuzwakalayo phakathi kwezindawo ezivalekile nezincane.

• I-Lightweight: Igwebu le-PU lezinga eliphansi lingafakwa ezintweni zokusebenza nezingxenye zemoto ngaphandle kokwengeza isisindo esikhulu.

• I-Flexible cushioning: igwebu elicindezelwayo lingabuye linikeze ukugoba phakathi kwezingxenye.

• I-Vibration damping: ilungele imihlangano ye-acoustic ne-NVH ekhethiwe lapho kokubili umsindo ovela emoyeni kanye nokuxhumana komshini kudingeka kucatshangelwe.

• Izinketho eziningi zokuminyana: ulwazi lomkhiqizo lwamanje luhlanganisa 22, 25, 28 kanye no-30 kg/m³.

• Ukusika ngokwezifiso: igwebu lingenziwa libe amashidi, amaphedi, imichilo kanye nezingxenye ze-acoustic ezimise okwe-acoustic.

• Ukusekela okunamathelayo: Igwebu elifanele le-PU lingenziwa elayiniwe nge-adhesive ezwela ukucindezela ukuze kufakwe kumaphaneli nasezindaweni zokusebenza zemishini.

• I-lamination yangokwezifiso: izinto ezibhekene nazo ezifanele noma ukwakhiwa okuyinhlanganisela kungahlolwa ngokuya ngesicelo esiqediwe.

Ulwazi Lomkhiqizo we-Acoustic Polyurethane Foam

I-Polyurethane Foam Technical Specification

Idatha elandelayo yobuchwepheshe iyasebenza ebangeni le-polyurethane foam elinikezwe njengamanje nalo mkhiqizo. Izakhiwo zokugcina zomzimba kufanele ziqinisekiswe ngokuya ngokuminyana okukhethiwe, ukujiya, ukwakheka kanye nesicelo esiqediwe.
