He aha te Laid Scrim? He aha te pai ake o te Polyester Laid Scrim Mesh i te papanga kupenga whatu mō ngā pakitara me ngā paipa
Ka pania e te kaimahi kirimana he paparanga hou o te whakairo ki te pakitara raima tawhito. I roto i ngā marama e ono, ka puta ngā kapiti i ngā hononga. I roto i ngā marama tekau mā waru, ka tīmata te tihore o ngā wāhanga o te whakaotinga mai i te papa. Ehara i te kounga o te paraikete, i te pūkenga rānei o te kaiwhakapiri te take matua—engari ko te korenga o tētahi paparanga whakapakari ā-mīhini i te atanga. Ko ngā kaihangarau me ngā kaiwhakatakoto e rapu ana i te "kakahu mata takai" "kakahu kupenga whatu" rānei, he maha tonu te ngana ki te whakautu i tētahi pātai matua ake: "he aha te scrim?" me te mea ka taea te ārai i ēnei hapa e puta tonu mai ana. Ka whakamāramahia e tēnei tuhingaWhakatakotoria he kiriuhi, e whakamārama ana me pēheaMatapihi Whakatakotoria PolyesterHe rerekē te hanganga mai i ngā momo raranga tuku iho, ā, e whakaatu ana he aha i pai ake ai te hangarau mō te ārai i te pakaru o te pakitara, te ngatata, me ngā mata kāore i te ōrite. Mō ngā tono paipa GRP,He mea hanga ki te polyester Scrim mō ngā paipae whakarato ana i ngā whakapainga ka taea te ine i te pumau o ngā hononga me te kaha pakaru mō te wā roa. Ko te tirohanga matua: ka tohatohahia e te kiriuhi kua whakatakotoria tika te ahotea whakaheke whakaora, ka ātete ki te pirau kawakore, ā, ka pupuri i te whakapakari kume rua-ahunga puta noa i te roanga o te mahi a te pūnaha.
Kaupapa Hangarau: Ngā Tikanga o te Whakatakoto i te Kiriata
Hanganga Rauemi
Whakatakotoria he kiriuhi(e kiia ana hoki koMatapihi Whakatakotoria) he papanga whakapakari whatu-tuwhera i hangaia mā te whakanoho i ngā miro whenu me ngā miro whatu kia whakarara tetahi ki tetahi i roto i te papa kotahi, ka herea ki ia pūwāhi whakawhiti me te whakapiri werawera, te whakapiri rapa rānei. He rerekē rawa tēnei i tepapanga kupenga whatu, e whiria ana ngā miro ki runga, ki raro hoki i tētahi, ka hanga he miro piko. I roto i te miro kua whakatakotoria, ka noho tika tonu ngā miro. Ina pāngia he kawenga kume, ka haere tika te kaha i te tuaka o ia miro, ka whakanui ake i te whai huatanga o te kaha ā-roto o te muka.
Te Tohatoha Anō i te Taumahatanga i roto i ngā Pūnaha Pakitara
Ina mārō te paninga turanga sima, te paninga turanga polymer rānei, ka heke te rahinga o te paparanga—i te nuinga o te wā i waenga i te 0.03% ki te 0.08% mā te whānuitanga raina. I runga i tētahi paparanga koretake, pūwero rānei, ka puta he kukū ahotea kume ā-rohe i ngā hapa moroiti, ngā āputa, me ngā taha o tēnei hekenga. Ki te kore he whakakaha, ka tīmata ēnei tihi ahotea i ngā kapiti moroiti e horapa ana ki te mata, ka puta te kapiti mapi āhuatanga, ā, ka mutu.te tihore i te pakitarae kitea ana i roto i ngā pūnaha kāore i whakapakaritia. He pūnaha kua whakauruhiaMatapihi Whakatakotoria ka ārai i ēnei kaha kume, ka tohatoha puta noa i te mata whatu katoa. Ko ia hononga honohono he pona whakawhiti kawenga. Mā te hanganga tuwhera—ko te nuinga he 60% ki te 75% te horahanga tuwhera—ka taea e te rauemi paninga turanga te uru katoa mā roto i te whatu, ka hangaia he wāhanga hiato kotahi, kaua he paparanga mata noa iho.
A Matapihi Whakatakotoria Polyestere whakamahi ana i ngā miro polyester maha-whiri tonu, ko te nuinga o ngā mata he 4 × 4 ki te 12 × 12 miro mō ia inihi, ā, ko te taumaha o te whenua he 30 ki te 80 karamu mō ia mita tapawha. Ka tīpakohia te kaihoko here kia rite ki te hototahitanga matū ki te pūnaha whakakikorua e whakaarohia ana—ahakoa he paninga sima, he paninga epoxy, he kapia polyester rānei.
Te Mahi i roto i te Paipa GRP
MōPolyester Scrim mō ngā Paipa GrpmeHe mea hanga ki te polyester Scrim mō ngā paipa, e rua ngā mahi a te whariki kua whakatakotoria. I te wā e hangaia ana te raima, ka mahi hei whakawehe i te matotoru e whakahaeretia ana, e ārai ana i ngā rohe whai rawa i te kapia, ā, e whakarite ana i ngā ōwehenga muka-ki-te-kapia ōrite huri noa i ngā āhuahanga uaua pērā i ngā tuke, ngā tī, me ngā kaki flange. I te wā e whakamahia ana, ka whai wāhi ki te whakakaha i te kume porowhita me te tuaka i ngā wāhi hononga e tino teitei ana te ahotea miihini me te wera.
E ai ki te whakamātautau pēhanga wai ātete i runga i te tikanga ISO 14692, ko te hononga paipa GRP 150 mm te whānui e whakauru ana i te paparanga kotahi o te polyester 65 g/m² scrim kua whakatakotoria he 15% ki te 22% teitei ake te pēhanga pahū ki te whakataurite ki te hononga ōrite kua whakakahangia me te whāriki miro tapatapahi anake he rite te matotoru katoa o te laminate.
Tohu mahi matua:I roto i ngā whakamātautau pakeketanga kawakore paerewa e whakaata ana i te wairewa pūwero sima (pH ≈ 12.5, 23°C, 28 rā), ka mau tonu te kaha kume o te whatu polyester kua whakatakotoria ki te rahi tika i te ≥ 80% o tōna kaha kume taketake. I raro i ngā āhuatanga ōrite, ko te mata karāhe-E paerewa—ahakoa he paninga ātete-kawakore—ka heke iho i te 50% te pupuri nā te pakaru waikura ahotea o ngā miro karāhe.
Ngā Horopaki Taupānga me ngā Otinga Hōhonu
Horopaki 1: Te Wehenga me te Ngatata o te Mata Pakitara i roto i ngā Kaupapa Whakahoutanga
I roto i ngā whakahoutanga arumoni me ngā whakahoutanga whare noho, kāore i te tino pai te papa. Tērā pea he rerekē te porosity o te raima tawhito, he toenga makuku mai i ngā turuturu o mua, he iti rānei ngā kapiti mai i te huringa wera. Mā te whakamahi i tētahi pūnaha peita hou ki runga i taua mata ka puta te korenga. Mā te whakauru i tētahiMatapihi Whakatakotoria Polyesterki roto i te paninga turanga e aro ana ki ngā tikanga pakaru e toru:
Horopaki 2: Te Hononga Paipa GRP me te Whakakaha i te Whakaurunga
I roto i ngā pūnaha paipa GRP ahumahi mō te maimoatanga wai, te tukatuka matū, te hinu me te hau rānei, ko ngā wāhi hononga te wāhi tino taumaha. Ka arotahi te huringa wera, ngā ngaru pēhanga, me te kawenga miihini ki ngā hononga pere-me-te-paipa, ngā urutau flange, me ngā takai whakatika.He mea hanga ki te polyester Scrim mō ngā paipa;Ko te whakamahinga i te wā o te whakarārangi ka whakarato:
Te tohatoha ōrite o te kapia huri noa i ngā piko uaua, e ārai ana i ngā rohe whai rawa i te kapia, i ngā rohe rānei e kore e nui te kapia.
Ka whakaitihia te nui o te moroiti-kore i te wā e whakamahia ana i muri tonu i te whakakorikori kapia, i mua hoki i te whakakorikori.
He whakakaha kume tāpiri mō ngā porowhita me ngā tuaka, me te kore e tino whakanui i te matotoru, te taumaha rānei o te raima.

Te kukū o te ahotea whakaheke:;Ka tohatohahia e te scrim ngā kaha kume puta noa i te pakitara, ka ārai i te tīmatanga o ngā kapiti ā-rohe.
Te wāhi noho o te nekehanga o te papa:;Ka whānui, ka whakawhāiti te papa i te huringa pāmahana me te makuku. Ka honoa e te kiriuhi ngā āputa tae atu ki te 0.3 mm, me te kore e horapa ngā kapiti ki te mata whakaoti.
Te whakaekenga matū kawakore:;Ka mau tonu te pH o ngā paninga turanga sima ki runga ake i te 10 mō ngā wā roa. He ātete ā-tinana ngā muka polyester ki te waikura me te whakaekenga kawakore, he rerekē ki ngā muka karāhe e memeha haere ana te kaha i roto i tēnei taiao.
Ngā Pātai Auau
He aha te rerekētanga i waenga i te papanga whatu miro me te papanga kupenga whatu?
Ko ngā miro whatu me ngā miro whatu o te whatu whakatakotoranga he mea whakanoho whakarara, he mea hono ki ngā wāhi e honoa ana, ā, kāore he piko. Ko ngā miro whiri me ngā piko o te papanga kupenga whatu he mea whakawhiti ki ia wāhi e honoa ana. Ko te hua mahi ko te whakawhiti pai ake o ngā kawenga kume i te taha o te tuaka miro, ā, ka takoto papatahi ki te papa, ka pai ake te makuku me te piri ki roto i ngā pūnaha paninga angiangi. He pai ake pea te papanga whatu ina hiahiatia he ātete pāmahana teitei i runga ake i te 180°C, engari mō ngā pūnaha pakitara kawakore me ngā paipa GRP pāmahana-taiao, ka tukuna e te polyester layed scrim te pumau roa.
Ka taea te whakamahi tika i te kiriuhi polyester ki runga i ngā pakitara haukū?
Kāore ngā miro polyester e mimiti i te wai, ā, e kore e pirau, e pupuhi rānei. Heoi, me pania te rauemi whakakikorua—te render, te sticky, te resin rānei—i roto i tōna ake matapihi ātete makuku. Kāore te scrim e whakakapi i te pūnaha paninga i pania ki waho o tōna rohe makuku kua tohua. Mō ngā pūnaha sima, me iti iho i te 16% te taumaha o te makuku o te papa.
Me pēhea taku whiriwhiri i te taumaha tika mō taku tono?
Kōwhiria te kiriuhi māmā rawa e tutuki ana i ngā whakaritenga ā-mīhini. Mō te whakapakari pakitara o roto, he rawaka te 40–55 karamu/m². Ko ngā pūnaha o waho e pāngia ana e ngā kawenga hau, e ngā mahi rū whenua rānei, me 70–85 karamu/m². Mō te takai paipa GRP, me 15–25% o te taumaha whakapakari katoa o te papa whakarewa whakamutunga te kiriuhi. Ka whakaitihia e ngā kiriuhi taumaha te āhua o te hanganga i runga i ngā radius piri.
Ka pāngia te mahi ahi a te huihuinga e te papanga matotoru kua whakatakotoria?
Ka mura te kiri polyester paerewa, ā, ka nui ake te kawenga wahie mēnā ka pāngia e te mura. Mō ngā huihuinga ahi-ātete, manatokohia kua paahitia e te pūnaha katoa—te papa, te paninga tuatahi, te kiri, me te paninga o runga—te paerewa e tika ana pērā i te ASTM E84 Akomanga A, EN 13501-1 rānei. Kei te wātea ngā kiri polyester ātete-mumura kore-halogen e eke ana ki ngā whakatauranga Akomanga A ina honoa ki ngā paninga intumescent.
Whakamutunga me te Whakapā Mai
Whakatakotoria he kiriuhi—inā koaMatapihi Whakatakotoria Polyester—e aro ana ki ngā take matua o te kiripaka o te pakitara, te ngatata, me ngā mata koretake mā te whakarato i tētahi paparanga whakapakari kore-kōpiri, pumau-kawakore, e utaina ana i ngā taha e rua. Mō ngā paipa GRP,He mea hanga ki te polyester Scrim mō ngā paipaka tukuna he whakapainga ine mō te pēhanga pahū hononga me te pono mō te wā roa. E tautokona ana ēnei painga e ngā raraunga ine—te pupuri kume i runga ake i te 80% i muri i te whakaraeraetanga ki te kawakore, te hononga pakaru tae atu ki te 0.35 mm, me te pikinga pēhanga pahū o te 15–22%—ehara i te mea nā ngā kereme hokohoko.
