ʻO ka uhi manhole material composite kahi ʻano o ka uhi manhole inspection, a wehewehe ʻia kona mau ʻano: hoʻohui ʻia ka uhi manhole inspection e kekahi kaʻina e hoʻohana ana i ka polymer e like me ka mea matrix, hoʻohui i nā mea hoʻoikaika, hoʻopiha, etc.
ʻO ka ʻoiaʻiʻo, ʻo ka uhi manhole resin (kahi i kapa ʻia ʻo polymer glass fiber reinforced plastic manhole cover/composite material manhole cover) he ʻano uhi manhole e hoʻohana ana i ka fiber aniani a me kāna mau huahana (ka lole aniani, tape, felt, yarn, etc.) i mea e hoʻoikaika ai. nā mea a me ka resin synthetic ma ke ʻano he matrix.Aia ia me ka resin polyester unsaturated, fillers, initiators, thickeners, low shrinkage additives, film mold agents, pigments and reinforcing materials, etc., a laila he ʻano hou o ka huahana uhi maikaʻi i hoʻoheheʻe ʻia i ke kiʻekiʻe wela.
Ma waena o nā mea i hoʻohuiʻia, nā mea i hoʻoikaikaʻia i ka fiber (ka lole aniani, ka tape, ka manaʻo, ka yarn, a me nā mea'ē aʻe) nā mea nui, iʻikeʻia e ka'umekau liʻiliʻi liʻiliʻi, ka ikaika kiko'ī nui a me ka modulus kiko'ī.No ka laʻana, ʻo ka mea i hoʻohui ʻia o ka carbon fiber a me ka epoxy resin, ʻo kona ikaika kikoʻī a me nā modulus kikoʻī he mau manawa ʻoi aku ka nui ma mua o ke kila a me ke alumini alumini, a he kūpaʻa kemika maikaʻi nō hoʻi, anti-friction a me ke kūpaʻa ʻana, lubricating ponoʻī, ke kū'ē wela, ka luhi luhi, ke kū'ē Creep, ka leo ho'ēmi, ka uila a me nā waiwai'ē aʻe.Hiki ke loa'a i ka composite o ka graphite fiber a me ka resini kekahi mea me ka ho'onui ho'onui aneane like me ka 'ole.ʻO kekahi hiʻohiʻona o nā mea i hoʻoikaika ʻia i ka fiber he anisotropy, no laila hiki ke hoʻolālā ʻia ka hoʻonohonoho ʻana o nā fibers e like me nā koi ikaika o nā ʻāpana like ʻole o ka huahana.Hiki i ka alumini matrix composites i hoʻoikaika ʻia me nā fila kalapona a me nā fibers silicon carbide hiki ke mālama i ka ikaika a me ka modulus ma 500 °C.
Hiki ke hoʻokaʻawale ʻia nā uhi manhole composite i BMC a me SMC e like me ke koi o ka mākeke, nā kaʻina hana like ʻole a me nā mea waiwai:
ʻO nā mea BMC (DMC) nā mea hoʻoheheʻe nui.Ua kapa pinepine ʻia ʻo ia ka unsaturated polyester bulk molding compound ma Kina.ʻO ka mea maka nui he prepreg e like me ka palaoa i hui pū ʻia e GF (ʻoki ʻia ke aniani fiber), UP (unsaturated resin), MD (filler) a me nā mea hoʻohui like ʻole.Ua hoʻohana mua ʻia nā mea DMC ma West Germany a me United Kingdom i nā makahiki 1960, a laila hoʻomohala ʻia ma ʻAmelika Hui Pū ʻIa a me Iapana i nā 1970s a me 1980s.No ka mea, ʻo ka BMC bulk molding compound he mau waiwai uila maikaʻi loa, nā waiwai mechanical, ke kūpaʻa wela, ka pale ʻana i ka corrosion, a hoʻololi i nā kaʻina hana hoʻoheheʻe like ʻole, hiki iā ia ke hoʻokō i nā koi hana o nā huahana like ʻole, a hoʻohana nui ʻia i ka hana kaʻa, kaʻa kaʻaahi, nā lako hana. , nā mea hana mīkini a me nā mea uila a me nā mea ʻē aʻe.
ʻO ka SMC composites nā mea hoʻoheheʻe pepa.Hoʻokumu ʻia nā mea waiwai nui me ka GF (ka lole kūikawā), UP (unsaturated resin), haʻahaʻa shrinkage additive, MD (filler) a me nā mea kōkua like ʻole.Ua ʻike mua ʻia ma ʻEulopa i ka makahiki 1960, a ma kahi o 1965, ua hoʻomohala ʻo ʻAmelika a me Iapana i kēia hana.I ka hopena o 1980s, ua hoʻolauna koʻu ʻāina i nā laina hana SMC holomua a me nā kaʻina hana.ʻO nā mea hoʻohuihui SMC a me kā lākou mau huahana SMC i hoʻoheheʻe ʻia he mau waiwai insulation uila maikaʻi loa, nā waiwai mechanical, kūpaʻa wela, a me ke kūpaʻa ʻana i ka corrosion.No laila, maʻamau ka laulā noi o nā huahana SMC.ʻO ke ʻano o ka hoʻomohala ʻana i kēia manawa ke hoʻololi i nā mea BMC me nā composites SMC.
I kēia manawa he hana nui ka hoʻohana ʻana i kā mākou uhi manhole resin i ko mākou ola, a kū i waho nā uhi manhole resin ma muli o kā lākou hana hoʻomaʻemaʻe ponoʻī.
ʻO ka hoʻohana ʻana i nā uhi manhole resin ma ke alanui he mau hiʻohiʻona o ka insulation, ʻaʻohe walaʻau, ʻaʻohe waiwai recycling a me nā anti-theft kūlohelohe.ʻAʻole hiki ke hoʻololi ʻia no nā uhi manhole hao.
Hana ʻia ka uhi manhole resin e kahi kaʻina hana hoʻoheheʻe kūʻokoʻa, kahi e ʻike hou ai ke kūlanakauhale.ʻO ke ola lawelawe he 20-50 mau makahiki.ʻO ka uhi manhole composite resin i hoʻokumu ʻia e ka hoʻoheheʻe ʻana i ka wela kiʻekiʻe ka maikaʻi o ke kaumaha māmā a me ka ikaika kiʻekiʻe, ke kūpaʻa luhi maikaʻi a me ka palekana pōʻino.Loaʻa iā ia nā pōmaikaʻi o ka hoʻoheheʻe maʻalahi, ka leo haʻahaʻa haʻahaʻa, ke kūpaʻa kino kino maikaʻi, ka waikawa maikaʻi a me ke kūpaʻa alkali a me ke ʻano nani, a ua hoʻemi hou ʻia nā mea haumia i ka wai.
I kēia manawa ma ka mākeke, ua hana ʻia nā uhi manhole i hana ʻia e nā mea hana like ʻole i nā mea like ʻole, akā ua like kekahi mau hiʻohiʻona:
1. ʻO ka hana anti-theft ikaika: Hana ʻia nā uhi manhole composite me ka resin unsaturated, fiber aniani a me nā mea ʻē aʻe ma o ke kaʻina hana kūikawā, a ʻaʻohe waiwai o nā huahana.ʻAʻole maʻalahi ka hoʻoikaika ʻana.
2. Ke ola lawelawe: Ma o ka hoʻohana ʻana i ka resin hana kiʻekiʻe, ke aniani aniani a me ke kaʻina hana hana kūikawā, ua hōʻoia ʻia ke komo ʻana o ka pūnāwai composite i loko o ka fiber aniani, a ua hoʻonui nui ʻia ka pili ʻana ma waena o nā mea ʻelua, i mea e hoʻonui ai ka waiwai. ʻaʻole e pōʻino ma lalo o ka hana o ka ukana cyclic.Loaʻa ka pōʻino i loko, no laila e hōʻoiaʻiʻo ai i ke ola lawelawe o ka huahana a me nā pono like o nā uhi manhole composite resin ʻē aʻe, e hoʻopau pono i ka hemahema o ka adhesion maikaʻi ʻole.
3. ʻO ke kūlana kiʻekiʻe / haʻahaʻa haʻahaʻa haʻahaʻa, ka hana insulation maikaʻi a me ke kūpaʻa corrosion ikaika: ʻo ka huahana he corrosion-resistant, non-toxic a me ka pōʻino.ʻAʻohe mea hoʻohui metala.Hiki ke hoʻohana ʻia i nā wahi paʻakikī a loli, paʻakikī a koi.Ua hoʻāʻo ʻia nā uhi manhole i hana ʻia e ka Bester composite manhole cover manufacturers e nā keʻena hoʻāʻo mana aupuni kūpono, a loaʻa i ka waika a me ka alkali kūpaʻa, corrosion resistance, anti-aging a me nā hōʻailona ʻē aʻe e kū ana i nā kūlana o ka huahana.
4. Nani a kūpono, kiʻekiʻe: e like me ka makemake o nā mea kūʻai aku kiʻekiʻe, hiki iā mākou ke hana i ka LOGO paʻakikī a me nā ʻano kala like ʻole ma ka ʻili o ka uhi manhole hoʻokahi hoʻolālā pilikino, i maʻalahi ke kumu, ke kala. he malamalama a maopopo.E like me nā koi o ka mea kūʻai aku, hiki ke hana ʻia i loko o nā hiʻohiʻona pōhaku hoʻohālike a me nā kala e like me nā papa pōhaku like ʻole.
5. Hiki ke hoʻoikaika ikaika: Hoʻohana ka lalo i kahi hoʻolālā hoʻolālā kūikawā, a ʻo ka fiber hoʻoikaika mau i hoʻohana ʻia i hana ʻia i nā mea e hōʻoia ai i ka hoʻohui ʻia ʻana o ka fiber a me ka lole aniani, i loaʻa i ka huahana kekahi mea hiki ke lawe.
6. ʻO ka palekana o ke kaiapuni, non-slip, haʻahaʻa haʻahaʻa: ʻaʻole e paheʻe ka uhi manhole ma hope o ka ʻōwili ʻia ʻana o ke kaʻa, a ʻaʻohe leo pepeiao ʻino a me ka pollution.
Ke kau ʻana i kahi uhi manhole composite, e hahai i kēia mau ʻanuʻu ʻehā:
1. Ma mua o ka hoʻokomo ʻana, pono e hoʻopaʻa ʻia ke kumu o ka uhi manhole, a e hoʻoholo ʻia ke anawaena o loko, ka lōʻihi a me ka laulā e like me ka nui o ka uhi manhole.
2. I ka hoʻokomo ʻana i ka uhi manhole composite ma ke ala sima, e hoʻolohe i ka luawai masonry pono e ninini ʻia me ka ʻiʻo, a pono e hoʻokumu ʻia kahi apo hoʻomalu ʻana ma ka ʻaoʻao no ka mālama ʻana ma kahi o 10 mau lā.
3. I ka hoʻokomo ʻana i nā uhi manhole composite ma luna o ke kahua asphalt, pono e nānā ʻia e pale aku i nā mīkini hana e ʻōwili pololei i ka uhi manhole a me ka noho lua e pale aku i ka pōʻino.
4. No ka mālama ʻana i ka nani o ka uhi manhole a me ke kākau lima a me ke kumu hoʻohālike, e makaʻala ʻaʻole e hoʻohaumia i ka uhi manhole i ka wā e ninini ai i ka asphalt a me ka sima ma ke alanui.
ala hoʻomohala:
(1) He lua wale nō kona ikaika ma mua o ka uhi ʻana o ka manhole plastic.Hiki iā ia ke lawe ma mua o 40 tons o nā kaʻa.
(2) ʻO kāna hana holoʻokoʻa ma waena o ka uhi pōhaku-plastic manhole a me ka uhi manhole pipili, ʻoi aku ka maikaʻi ma mua o ka paʻa;hiki ke hoʻohana i nā manawa me nā koi ʻenehana kiʻekiʻe no nā uhi manhole.
(3) ʻO kāna mea maikaʻi loa, ʻaʻole ia e hoʻohana i ka hoʻoikaika ʻana i ka iwi kila, akā hoʻoikaika ʻia me ke aniani fiber composite, nona nā huahana ʻano GRC.No laila, loaʻa iā ia ka pōmaikaʻi o ka loaʻa ʻole o ka hopena i ka wā e piʻi mau ai ke kumukūʻai o ke kila.No ka mea, ʻaʻole i loko o ka hao liʻiliʻi, ʻoi aku ka pale ʻana i ka ʻaihue ma mua o ka poʻe palaki pōhaku a me nā uhi manhole fiber concrete.
(4) ʻOi aku ka wikiwiki o kona ho'ōla ʻana ma mua o ka fiber concrete, a hiki ke hoʻopau ʻia i nā hola 8.Inā hana ʻia i ʻekolu hoʻololi, hiki ke hoʻohaʻahaʻa ʻia i ʻekolu manawa i 24 mau hola.ʻOiai ʻoi aku ka nui o ka ʻeleʻele ma mua o ka plastik pōhaku, ʻo 1/6 wale nō ia o ka uhi manhole fiber concrete.Hiki iā ia ke hōʻemi i ka hoʻopukapuka mold.Me ka hoʻopuka makahiki o 10,000 sets of manhole covers, pono 10 sets of molds wale nō.
(5) He mea maikaʻi loa ka uhi manhole composite, ʻoi aku ka maikaʻi, a ʻaʻole hiki ke hoʻohālikelike ʻia me nā poʻi ʻē aʻe (e like me nā mole kaila, nā mole plastic, nā aniani fiber reinforced plastic molds).
(6) I ka hoʻomau mau ʻana a me ka hoʻonui ʻana o ka uhi manhole composite, ua ʻoi aku nā ʻano hōʻailona like ʻole ma mua o ke kūlana ʻoihana o ka Ministry of Construction, a ua hōʻea i ke kūlana maikaʻi o ka ʻoihana uhi manhole o koʻu ʻāina.
