ʻO ka SMC composite material ka pōkole o ka Sheet molding compound. ʻO ka mea nui o ka maka he GF (special yarn), UP (unsaturated resin), low-shrinkage additives, MD (filler) a me nā mea hoʻohui like ʻole. Ua ʻike mua ʻia i nā makahiki 1960 mua ma ʻEulopa, i ka makahiki 1965 a i ʻole, ua hoʻomohala ʻo ʻAmelika a me Iapana i kēia kaʻina hana. ʻO Kina i ka hopena o nā makahiki 80, ka hoʻolauna ʻana i nā laina hana SMC holomua a me nā kaʻina hana. ʻO SMC composites a me kāna mau huahana SMC i hoʻoheheʻe ʻia, me nā waiwai insulation uila maikaʻi loa, nā waiwai mechanical, thermal stability, chemical corrosion resistance. No laila, maʻamau ka laulā noi o nā huahana SMC.

Hoʻohana ʻia nā uhi lua e uhi i nā alanui a i ʻole nā ​​luawai hohonu ma ka home e pale ai i ka hāʻule ʻana o nā kānaka a i ʻole kekahi mea. Wahi a ka mea, hiki ke hoʻokaʻawale ʻia i loko o ka uhi manhole metala, kiʻekiʻe ka ikaika fiber cement concrete manhole uhi, resin manhole uhi a pēlā aku. He poepoe. Hiki ke hoʻohana ʻia no ke kāʻei ʻōmaʻomaʻo, alahele, alanui kaʻa kaʻa, dock, alley a pēlā aku.

SMC molded manhole uhi, he hou 'ano o ka waihoʻoluʻu kiʻekiʻe-ikaika manhole uhi, me ka hoʻohana 'ike loea hou a me nā lako hana hoʻoheheʻe, e ka 'Oihana o ke kukulu ana, ka National Center no ka Quality Supervision a me ka Inspection o Construction 'enekinia, ke kaumaha-duty manhole uhi o ka amo. hiki i ka 400KN a ʻoi aku paha, ʻoi aku ka nui ma mua o ke kūlana aupuni o 240KN, a ma ka manawa like, ma hope o ka National Center for Quality Supervision and Inspection of FRP hoʻāʻo, ʻoi aku ka nui o ka aging-resistant index ma mua o ke kūlana aupuni. Hiki ke hoʻohana maʻamau ka huahana mai -40 ℃ a 90 ℃. ʻOi aku ka lōʻihi o ke ola o ka lawelawe ma mua o 5-10 mau makahiki, a ʻoi aku ka lōʻihi o ka hana ʻana i nā koi honua o nā huahana like, a he huahana hou ia e pani ana i nā ʻano uhi manhole. Hoʻohana nui ʻia i ke kaona, pipeline, channel, lako mana, lako wai a me nā papahana ʻē aʻe.
