一, PPI leh PA inthlauhna hrethiam rawh .
Silicone sponge kan thlan hian parameter pahnih PPI leh PA kan tawk fo thin. PPI, emaw inch khata hole awm zat hi sponge-a hole density tehna unit a ni a, PA (Pascal) erawh chu pressure tehna unit a ni thung. Heng pahnih hian property hrang hrang an entir a. PPI hian silicone sponge structural characteristics a sawi a, PA erawh chuan silicone sponge performance chu aspect engemaw takah a sawi thung a, chu chu pressure resistance ang chi a ni. Silicone sponge thlan dawnin PPI hi tehna indicator atan a tha zawk. PPI sang hian silicone sponge pores te chu a denser zawk tihna a nih avangin a tlangpuiin sound absorption leh heat preservation effects tha zawk a pe thei a ni.
Mahse, PA hian pressure unit angin silicone sponge quality leh performance chu direct-in a hril lo. A hmanna tur bik scenario-ah chuan hman a ni zawk a, chu chu silicone sponge-a compressive strength tehnaah a ni.
2,40PPI leh 60PPI inkar a tehkhin theih a ni.
Silicone sponge PPI kan ngaihtuah lai hian 40ppi leh 60ppi inkar kan hreh fo thin. A pahnih inthlauhna ber chu hole density leh a lo chhuak physical property-ah a awm a ni.
1. 40ppi silicone sponge hian hole lian zawk leh boruak permeability tha zawk a nei a, hei vang hian ventilation performance sang zawk mamawh environment-a hman atan a tha hle. Chubakah, khur lian tak tak pawh hian hetiang sponge chi hi tihfai a awlsam zawk a, leivut a khawlkhawm tlem zawk tihna a ni bawk.
2.Chumi danglamna chu 60ppi silicone sponge hian hole a denser a, hei hian sound insulation leh heat preservation lamah a thawk tha zawk. Mahse, dense holes hian boruak permeability a ti chhe hle thei a, tihfai pawh a harsa zawk thei bawk.
Duhthlan tur i siam dawnin, boruak hipna leh tihfai awlsam zawk i ngaih pawimawh chuan 40ppi silicone sponge hi a tha zawk ang. Sound insulation leh heat preservation effects te hi ngaih pawimawh zawk a nih chuan 60ppi silicone sponge hi a tha zawk ang.
Tawpna:
Eng PPI silicone sponge nge hman tur tih thlan tur chu i mamawh bik ah a innghat ber. General scenario tam zawk tan chuan 40ppi sponge hi a mamawh phuhrukna tur a tling tawh a ni. Mahse, sound insulation tha zawk emaw heat preservation effects emaw i mamawh chuan 60ppi sponge hi a tha zawk. Duhthlanna i siam dawnin, mi pakhat chuan sponge-a application scenario bik leh parameter dangte, hardness, thickness, leh temperature resistance range te pawh ngaihtuah tel theih a ni a, chu chu ngaihtuah chian theih a ni.
Parameter PA chungchangah chuan, a tlangpuiin pressure resistance capacity tehna atana hman tur scenario bikteah chuan main selection basis atan hman a ni lo.
