'īpale kumuhana no kaʻohe i ka polyethylene hua: no ka nui, ano, kiʻi

I ka waiho ana a me ka hana ana o pipelines o kekahi ano i koi mākaʻikaʻi hana i kekahi mau rula, i ole oe e halawai me nā'ēheu kēia'ēheu o ka pilikia.

ka nele i ka hana

Sewer a me ka wai paipu, a i aia mawaho paha ma loko o ka unheated wahi maikai, ke pa ahau. Me ka pili ana i ka paio hahana maoli nō'ōnaehana, ka mea pono e pale aku wela poho, e like me ka pono me ka malama ana i kekahi ana wela o ka coolant. No ka hoomalu ana i loko o ka mea i ho'ākāka 'ia hihia hoʻohana heaters no kaʻohe i ka polyethylene hua.

Key Hiʻona

Ka luna i oleloiaʻia mai i nā hana 'ole i ka he o ka poe liilii, hoailonaia he keena, kona nuʻa hiki e like me ka huahelu ma ka laulā mai ka 25 a hiki i 40 kilograms no cubic mika. Polyethylene ua maikaʻi elasticity a hiki i ka wa i hooleiiaʻi mawaho i haʻahaʻa mahana, a me kona waiwai e ole hoʻololi i ka laulā ma waena o -60 a me +90 degere. Kēia Hōʻike hiki e hoʻouka kekahi i ka'īpale no kaʻohe i ka polyethylene hua ma lalo o kekahi malie ana. Ka hua nui polyethylene'īpale kaʻi lau waiwai kiʻekiʻe lawa, mai ka thermal conductivity mea haʻahaʻa a me ka loli aʻe mai ka 0.038 a hiki i 0,039. Wai mahu permeability ka 0,001, e leie aku ka mea e h ÷ ike i ka mea e like ai o ka piha mahu e kū'ē'ē mai. He malalo i na wahie, a me ka mea nui o kēia mau mea i ka kii o 0,3 MPa. 'īpale no ka wai heʻohe kani o ka polyethylene hua mai i ka leo omo i ka 16 decibels, no laila, me ka lako e ua excellently absorbs leo a me kuekueni i i ala mai i ka hoʻohana 'ana o ka pipeline nenoai. It E ke kaulana a me ka maikaʻi hydrophobicity mea, ke'ōlelo mai ma ka hui 'ana me ka wai a mea hiki ia e ke kemu ma ka hope 1% o ka nui o ka leo. Ke kiekie loa ana o ka wai omo mea 3.5%. Ia mea ke kumu ke kapaia 'aʻole i imply i ka pono no ka waterproofing hana, no ka mea,ʻaʻole i ka' ilikai, e hana i ka condensate. Heat'īpale no kaʻohe i ka polyethylene hua excellently Makuakane me ka ole o ka chemically hana waiwai o ke 'ano o ke kakolina, kaʻaila, nāʻakika a me alkalis.

hou hiʻona

Ho'ākāka 'ia ma'īpale ua ua hanaʻia e like me GOST 30244-94. Ka hua nui polyethylene hiki ke hoʻolaha like moderately combustible mea, o ka mea hō'ā kaʻa mahana i loko o ka pololei lapalapa waiū o ka 306 degere. No ka mea pakiko-mea hō'ā kaʻa o 416 degere Ua lawa. Naʻe, ka mea, ua manaoia he hou lanakila i ka'īpale mea iʻawahia, a hiki i ka wa a ke ahi i loko o ke kaʻina hana, ka mea, 'aʻole i hoʻokuʻu akula nā palapala ma ka ohu i ka kanaka kino,.

maikaʻi 'ano

Inā 'oe e hoihoi i loko o'īpale no kaʻohe i o polyethylene hua, oe e noonoo i kona pono. Muli o kona kulana pinepine, i ka lako e ua like me ka polystyrene hua a me ka polyurethane hua, nolaila, ke hoomaopopo i na pono, i waena o lākou - hōʻemi iki thermal conductivity, ma i mea hiki ia i ka mana o ka wepa i mea he uuku mānoanoa. Ia e ke kaulana, a na kekahi mea e like ai me tensile ikaika, a me ka maikai hiki i ka loiloi mua palapala, e hoihoi mai ma hope o deformation. Ma ka hua ke loli lepo pipili, gypsum, Lime a me ka pōhaku puna, me ka hoʻokaeʻili i ka qualitative ano. No ka mea, i ka hōʻike iaia? Aaaoaeuiuo mea pono ole nae,ʻaʻole wale no kānaka akā, no hoi no ka mea i hoʻolilo 'ia, ka mea, uaʻaeʻia e hoʻohana i loko o ka hana, ma ka hale, i loko o ka haukapilaʻo a me ka hui ana o ka meaʻai hana. Polyethylene i na ano o ka hydrophobicity e hana aku ana i ka hoʻopau i ka hanana o ka punahelu, a me ka punahelu. Ia e ke kaulana, a me ka nanea o ka mea hoʻonoho, 'ole. To. Products i loko o ka palapala o ka puha paipu i ke hoʻohana hiki no i pōkole manawa e hoʻomehana i ka paipu, ka hoʻohana' ana i nā mea hana a me ka lako a pan no keia mea. Material kāki He 2 manawa haʻahaʻa ma e like me ka like pāʻoihana, i mea aha kēiaʻano o ka'īpale hoʻohanaʻia e nā mea kūʻai mai i increasingly.

Kekahi o ka hopena maikaʻi 'ano

Thermal'īpale no kaʻohe i ka polyethylene hua, e hōʻike mai iā ia i nā 'ano o ka i loko o ka' atikala, ua kekahi mau keakea, i waena o lākou, e like me ka olelo maluna, i ka hiki e hānai iā'ā a me ka flammability ka wā lapalapa waiū. No keia kumu, ka mea hiki ole hoʻohana i ka iauaeoia i mea e halawai kiʻekiʻe ahi maluhia koi. I waena o nā mea a pau, hua collapses ma lalo o ka aoao o ka pololei Map. Kēia Hōʻike i ka pono, e hoahu, a malama i ka ohe'īpale i loko o ia mau wahi, kahi i hoʻokoe 'ia mai komo ultraviolet. E hoʻoponopono i kēia pilikia, he lako e ua koho i ka mea he opaque Auana. Hewa wale compensated e ka luna-i oleloia pono.

Ana a me kekahi 'ē aʻe ano

Inā e koho, e hoʻohana'īpale no kaʻohe i o polyethylene hua, i ka nui o ka i hiki ĸokoĸa ana nä pane mai 6 a hiki i 160 mm o, ia mea pono eʻike i nāʻano likeʻole o kona ho. Penei, o ka pā kona mānoanoa i e like me ka huahelu ma ka laulā o ka eono a hiki i ke kanakolu-nā millimeters. I ka makeke ke loaʻa i ke paipu'īpale, a ua hoolako ia me ka kūikawāʻili lahilahi, me he pōpō polymeric ka penaʻana. Ua i malama i ka la, waiū, e leie aku ka hoʻohana 'ana i kēia mau huahana, a hiki ma ka wahi i i mau paku ole ia i ultraviolet malamalama. I waena o nā mea a pau,'īpale no kaʻohe i ka polyethylene hua, i nā kiʻi i hōʻike mai iā ia i loko o ka pauku e ia i ka pepa a me ka'ōwili. I kekahi manawa, i hana ole'īpale complemented Wahi lina.

Ka 'ole o ka iwi

hoʻokaʻawale palapala pono halawai kekahi mau koi e ae ia e hoopuni i ka ili me ka palena haʻahaʻa wahi i wāhiʻia. Ka mea pono ole ke ino, a me ka palapala pono i ka kekahi anawaena. Wale i loko o kēiaʻaoʻao, e e hiki ia i ka nui ana o ka'īpale. E hōʻoia 'oluolu mea hoʻonoho ma ka Tube, e like me ka rula, ia mea heʻanoʻenehana incision, e leie aku a e e mea hoʻonoho hana i loko o ka shortest hiki manawa, a ma na nenoai i keia manawa, hoʻouka kekahi.

Hiʻona o ka mea hoʻonoho

Inā 'oe e hoʻoholo ai i ka hana no ka 'īpale,'īpale no kaʻohe i o polyethylene hua, anawaena mea pono e koho i ka loa hemolele. Ma hope o ia, ia mea pono e hahai i ka mea hoʻonoho o ka 'ike loea hou'īpale. i hoʻomākaukau paipu no ke kaʻina hana, a me kā lākou ili honua ua ua holoiʻia mai ka lepo a me ka lepo. Polyethylene ua kau aku ma luna o ka stocking type i pono ole e pili me ka pakahi pilikia. Ua hiki ke hana ia ma ka ohe,ʻaʻole i hoʻouka kekahi, i ka'īpale e ole e poino i ka pahi.
