Ngāwari
Mā te ngāwari o te paipa polyethylene ka taea te piko ki runga, ki raro, ki te taha hoki o ngā arai, tae atu ki te whakarerekē i te teitei me te ahunga.I ētahi wā, mā te ngāwari o te paipa ka kore rawa e whakamahia ngā hononga, ka tino whakaitihia hoki ngā utu tāutanga.
Ka taea te whakapiko i te paipa PE CHUANGRONG ki te iti rawa o te radius i waenga i te 20 ki te 40 ngā wā o te diameter o te paipa, e whakawhirinaki ana ki te SDR o te paipa kua whakaritea.

Taumaha Māmā
Te roa o te oranga
Ko te matotoru o te rauemi PE he 1/7 noa iho o te matotoru o te maitai. He iti ake te taumaha o te paipa PE i te matotoru o te rino maka raima, o te paipa maitai rānei. He ngāwari te whakahaere me te tāuta i te pūnaha paipa PE, ā, mā te whakaiti i te kaha tangata me ngā taputapu ka taea te penapena i te tāutanga.
Ko te pūtake hoahoa waipū mō te paipa CHUANGRONG e ahu mai ana i ngā raraunga whakamātautau waipū whānui i arotakengia e ngā tikanga ahumahi paerewa. Ko te whanonga roa mō ngā ātete pēhanga ā-roto e whakaratohia ana e te pihi kaha waipū i runga i te paerewa EN ISO 15494 (tirohia te wāhanga X). Ko ngā rohe tono mō ngā paipa me ngā hononga, e whakaaturia ana i roto i te hoahoa pēhanga-pāmahana, ka taea te ahu mai i ēnei pihi, e whakaatu ana he 50 tau te roa o te ora o te paipa ina kawe wai i te 20℃. Ka taea e ngā āhuatanga taiao ā-roto, ā-waho hoki te whakarerekē i te roa e tumanakohia ana, te whakarerekē rānei i te pūtake hoahoa kua tūtohutia mō tētahi tono.
Ātete ki te Huarere
Ngā Āhuatanga Wera
Ka puta te pirau o ngā kirihou mā te tukanga o te pirau o te mata, te waikura rānei, nā te pānga o te hihi ultra violet, te pikinga o te pāmahana, me te makuku ina rongoatia ngā paipa ki ngā wāhi e kitea ana. Ka taea te rongoa haumaru i ngā paipa polyethlence mangu, kei roto ko te 2 ki te 2.5% o te pango waro kua wehea pai, i waho i te nuinga o ngā āhuarangi mō ngā tau maha me te kore e kino mai i te pānga ultra-violet. Ko te pango waro te tāpiri kotahi tino whai hua hei whakarei ake i ngā āhuatanga pirau o ngā rauemi kirihou. Ko ētahi atu tae pēnei i te mā, te kikorangi, te kōwhai, te papura rānei, kāore i te rite te pumau ki ngā pūnaha tae pango, ā, me whakawhāiti te wā whakaaturanga ki te kotahi tau kia pai ai te pupuri i ngā āhuatanga. Mā ēnei pūnaha tae ka tere ake te whanake o ngā paparanga waikura o te mata o waho i ērā o te pango waro.
ngā paipa PE kua whakau. Kāore ēnei paipa tae i te tūtohutia mō ngā mahi i runga ake i te whenua.
Ka taea te whakamahi i ngā paipa polyethylene i ngā pāmahana mai i te -50°C ki te +60°C. I ngā pāmahana teitei ake, ka whakaitihia te kaha kume me te pakari o te rauemi. Nō reira, tirohia te hoahoa pēhanga-pāmahana. Mō ngā pāmahana i raro iho i te 0°C, me whakarite kia kore te rauemi e tio, kia kore ai e kino te pūnaha paipa.
Pērā i ngā kirihou wera katoa, he nui ake te whānuitanga wera o te PE i te konganuku. Ko te tauwehenga o te whānuitanga wera raina o tā mātou PE he 0.15 ki te 0.20mm/m K, he 1.5 ngā wā nui ake i tērā o te PVC. Nā te mea ka whakaarohia tēnei i te wā e whakamaheretia ana te tāutanga, kāore he raruraru e pā ana ki tēnei.
Ko te kawe wera ko te 0.38 W/m K. Nā ngā āhuatanga whakamarumaru ka puta, he nui ake te ohanga o te pūnaha paipa PE i te pūnaha i hangaia ki te rauemi pēnei i te parahi.
Te Whanoke o te Tahunga
![V17B]@7XQ[IYGS3]U8SM$$R](http://cdn.globalso.com/cdchuangrong/V17B@7XQIYGS3U8SMR.jpg)
Nō roto te polyethylene i ngā kirihou mura. Ko te taupū hāora he 17%. (Ko ngā rauemi e mura ana me te iti iho i te 21% o te hāora i te rangi ka kiia he mura).
Ka maturuturu te PE, ā, ka mura tonu, kāore he pungarehu i muri i te tango i te mura. Ko te tikanga, ka tukuna ngā matū paitini e ngā tukanga mura katoa. Ko te hauhā waro te hua mura tino morearea ki te tangata. Ina mura te PE, ko te hauhā waro, te hauhā waro me te wai te nuinga ka puta.
Ko te pāmahana mura-ā-ake he 350℃.
Ko ngā mea tinei ahi e tika ana ko te wai, te pahuka, te hauhā waro, te paura rānei.
Ātete Koiora
Tērā pea ka pāngia ngā paipa PE e ngā pūtake koiora pērā i ngā pōpokorua, ngā kiore rānei. Ko te ātete ki te whakaekenga ka whakatauhia e te pakeke o te PE e whakamahia ana, te āhua o ngā mata PE, me ngā āhuatanga o te whakaurunga. I roto i ngā paipa iti te diameter, ka pāngia pea ngā wāhanga pakitara angiangi e ngā moko i ngā wā tino kino. Heoi, ko te kino e pā ana ki te whakaekenga a ngā moko i roto i te PE kua kitea i muri mai ko ētahi atu pūtake o te kino ā-ringa.
Kāore ngā rauropi koiora e pāngia ana e ngā pūnaha paipa PE i uta, i te moana hoki, ā, ko te āhua paraffinic o ngā mata o ngā paipa PE ka whakaroa i te hanga paru moana i te wā e whakamahia ana.
Ngā Āhuatanga Hiko
Nā te iti o te mimiti wai o te PE, kāore ōna āhuatanga hiko e pāngia e te pa tonu ki te wai. Nā te mea he pūhui hauwai kore-porowhita te PE, he ārai pai rawa atu. Heoi, ka taea te kino haere o ēnei āhuatanga nā te parahanga, ngā pānga o ngā mea whakahāwea, te huarere rānei. Ko te ātete rōrahi motuhake he >1017 Ωcm; ko te kaha dielectric he 220 kV/mm.
Nā te mea ka puta pea ngā utu hiko, me tūpato i te wā e whakamahia ana te PE i ngā tono e tūpono ana te mōrearea o te ahi, o te pahūtanga rānei.
CHUANGRONGHe kamupene whakauru ahumahi me te hokohoko hea a C.U., i whakatūria i te tau 2005, e arotahi ana ki te hanga paipa, hononga me ngā takirere HDPE, paipa PPR, hononga me ngā takirere, hononga kōpeketanga PP me ngā takirere, me te hoko mīhini whakarewa paipa kirihou, taputapu paipa, rawhi whakatika paipa me ētahi atu.
