ʻO ka uhi manhole material composite kahi ʻano o ka uhi manhole nānā, a wehewehe ʻia kona mau hiʻohiʻona: 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 nā composites SMC he mau 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 o ke kino.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 kiʻekiʻe, ka fiber aniani a me ke kaʻina hana hana kūikawā, ua hōʻoia ʻia ke komo ʻana o ka uhi pūnāwai composite i loko o ka fiber aniani, a hoʻonui nui ʻia ka pili ʻana ma waena o nā mea ʻelua, i mea e pono ai ka mea. 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 ʻoihana hoʻāʻo mana aupuni kūpono, a loaʻa i ka waika a me ka pale alkali, ke kūpaʻa corrosion, anti-aging a me nā mea 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 ka ʻili o 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 kona pōmaikaʻi koʻikoʻi ʻaʻole ia e hoʻohana i ka hoʻoikaika ʻana i ka iwi kila, akā ua 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 ʻāpana ʻē aʻe (e like me nā mold rubber, nā ʻōpala palaki, nā mold plastic fiber glass 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.
