Application of SMC isolasiebord in motorveld

Die toepassing van SMC-isolasiebord in die motorveld:

Non-metallic materials used in automobiles include plastics, rubber, adhesive sealants, friction materials, fabrics, glass and other materials, involving petrochemical, light industry, textile, building materials and other related industrial sectors, so non-metallic materials are used in automobiles It reflects the comprehensive economic and technological strength of a country, and also includes the technological development and application capabilities of a large number of related industries. Glass fiber reinforced composites currently used in automobiles include: glass fiber reinforced thermoplastic (GFRTP), glass mat reinforced thermoplastic (GMT), sheet molding compound (SMC), resin transfer molding (RTM), and hand lay-up FRP products. The glass fiber reinforced plastics used in automobiles mainly include: glass fiber reinforced PP, glass fiber reinforced PA66 or PA6, and a small amount of PBT and PPO materials. Enhanced PP is mainly used to make engine cooling fan blades, timing belt upper and lower covers and other products, but some products have poor appearance quality. Due to defects such as warpage, non-functional parts are gradually replaced by inorganic fillers such as talc and PP.

Versterkte PA-materiaal is in passasiersmotors en kommersiële voertuie gebruik, en word oor die algemeen gebruik om ‘n paar klein funksionele onderdele te maak, soos: slot lyfskerms, veiligheidswiggies, ingeboude moere, versnellerpedale, skuif boonste en onderste skerms ‘n Beskermende omhulsel, opening hanteer, ens., as die kwaliteit van die materiaal wat deur die onderdelevervaardiger gekies is onstabiel is, die produksieproses onbehoorlik gebruik word of die materiaal nie goed gedroog is nie, sal die swak deel van die produk breek. Plastiek inlaatspruitstuk is ‘n nuwe tegnologie wat in onlangse jare ontwikkel is. In vergelyking met aluminium gegote inlaatspruitstuk, het dit die voordele van ligte gewig, gladde binneoppervlak, skokabsorpsie en hitte-isolasie, ens., so dit word wyd gebruik in buitelandse motors. Die materiale wat daarin gebruik word, is almal glasveselversterkte PA66 of PA6, hoofsaaklik deur die samesmeltingkernmetode of vibrasiewrywingsweismetode te gebruik. Op die oomblik het relevante huishoudelike eenhede navorsing op hierdie gebied gedoen en gefaseerde resultate behaal.
