Chinese 3PE anticorrosive ígwè anwụrụ emeputa
1. Belata ụgwọ ọrụ
Dị ka ngụkọta oge nke ngalaba ndị dị mkpa, n'ozuzu, polyurethane mkpuchi mkpuchi ígwè ọkpọkọ nwere ike ibelata oru ngo na-eri site banyere 25% (iji FRP dị ka nchekwa oyi akwa) na 10% (iji elu-density polyethylene dị ka nchekwa oyi akwa).
2. Obere okpomọkụ ọnwụ na ike ịzọpụta
Thermal conductivity nke polyurethane bụ: λ = 0.013-0.03kcal / m · h · OC, nke dị nnọọ ala karịa ndị ọzọ na-eji pipeline mkpuchi ihe n'oge gara aga, na mkpuchi mmetụta na-mma site 4 ~ 9 ugboro. Ọzọkwa, nnabata mmiri ya dị ntakịrị, ihe dịka 0.2kg / m2. Ihe kpatara ntinye mmiri dị ala bụ na ụfụfụ polyurethane nwere porosity mechiri emechi nke ihe dịka 92%. Low thermal conductivity na obere mmiri absorption, yana thermal mkpuchi oyi akwa na elu-njupụta polyethylene ma ọ bụ FRP nchebe shei na ezigbo waterproof arụmọrụ n'èzí, agbanweela ọnọdụ nke "yi mmiri owu padded jaket" nke omenala trenchi Ịtọ okpomọkụ ọkọnọ pipeline, na nke ukwuu. belata mkpokọta okpomọkụ ọnwụ nke pipeline okpomọkụ. Ọnwụ ọkụ nke netwọk okpomọkụ bụ 2%, nke dị ntakịrị karịa ọkọlọtọ mba ụwa chọrọ 10%.
3. Mgbochi corrosion, ezigbo mkpuchi na ogologo ndụ ọrụ
N'ihi na polyurethane siri ike ụfụfụ mkpuchi mkpuchi na-ejikọta ya na akpụkpọ anụ dị n'èzí nke ọkpọkọ ígwè, ntinye nke ikuku na mmiri nwere ike ịdịpụrụ adịpụ, enwere ike nweta mmetụta anticorrosion dị mma. N'otu oge ahụ, a na-emechi pores ya na-afụ ụfụfụ na ntinye mmiri ya dị ntakịrị. Nnukwu njupụta polyethylene shei na FRP shei nwere ezigbo mgbochi corrosion, mkpuchi na akụrụngwa akụrụngwa. Ya mere, akpụkpọ anụ dị n'èzí nke ọkpọkọ ígwè na-arụ ọrụ siri ike ka ikuku na mmiri dị n'èzí mebie. Ọ bụrụhaala na a na-emeso mma mmiri dị n'ime nke pipeline nke ọma, dị ka data mba ọzọ si kwuo, ndụ ọrụ nwere ike iru ihe karịrị afọ 50, nke bụ 3 ~ 4 ugboro karịa nke ịtọgbọ trenchi ọdịnala na ntinye n'elu.
E jiri ya tụnyere usoro mkpuchi ọkpọkọ ọdịnala, ọkpọkọ nchara mkpuchi e liri ozugbo nwere nnukwu uru:
1.The prefabricated ozugbo lie ikpuchi mkpuchi ígwè ọkpọkọ adịghị mkpa na-ewu a nnukwu trenchi, ma ọ bụ naanị mkpa na-eli ndị insulated ọkpọkọ n'okpuruala, nke ukwuu ebelata ala ọrụ nke oru ngo, na-eme ka gburugburu ebe obibi nchebe, na-ebelata ego nke earthwork gwupụtara site ọzọ. karịa 50%, ma na-ebelata ọnụ ọgụgụ nke masonry obodo na kọmpat site 90%. N'otu oge ahụ, a na-arụ ọrụ ọkpọkọ mkpuchi n'otu n'otu na trenching na saịtị ahụ, ọ bụ naanị njikọ dị na saịtị a chọrọ, nke nwere ike belata oge owuwu ihe karịrị 50%.
2.Ọrụ nchekwa ọkụ dị mma, na ọnwụ okpomọkụ bụ naanị 25% nke ọkpọkọ omenala. Ịrụ ọrụ ogologo oge nwere ike ịchekwa ike dị ukwuu ma belata ọnụ ahịa ume nke ukwuu.
3.Ọ nwere mgbochi mmiri siri ike na nguzogide corrosion. Ọ dịghị mkpa ka itinye ọkpọkọ trenchi. Enwere ike lie ya ozugbo na ala ma ọ bụ mmiri. Ihe owuwu ahụ dị mfe ma dị ngwa ngwa, ọnụ ahịa zuru oke dị ala.
4. Ọ nwekwara ezigbo nguzogide corrosion na nguzogide mmetụta n'okpuru ọnọdụ okpomọkụ dị ala, enwere ike lie ya ozugbo n'ime ala oyi kpọnwụrụ akpọnwụ.
5.Ndụ ọrụ nwere ike iru afọ 30-50. Nrụnye ziri ezi na iji ya mee ihe nwere ike ime ka ụgwọ mmezi nke netwọkụ ọkpọkọ dị ala.
6. Enwere ike ịtọ sistemu mkpu ka ọ chọpụta na akpaghị aka mperi mperi netwọkụ ọkpọkọ, gosi nke ọma ebe mmejọ na mkpu na-akpaghị aka.
