Ko te mara o te ārai-waikura te wāhi i uru wawe mai ai te hangarau polyurea, ā, kua whānuitia te whakamahinga i roto i te hangarau. Kei roto i ōna whakamahinga te ārai-waikura o ngā hanganga maitai pērā i ngā paipa, ngā tāke rokiroki, ngā tauranga, ngā pou maitai, me ngā tāke rokiroki matū. He matotoru te paninga rauemi, he kore hononga, he kaha te ārai-uru me te waikura, ka taea te tu atu ki te nuinga o ngā waikura matū, ā, ka taea te whakamahi mō te wā roa i roto i ngā taiao o waho me te waikura kaha pērā i ngā repo, ngā roto, te hinu tote, me ngā wāhi toka me te kore e paura, e ngatata, e tihore rānei. He pai te ātete ki te huarere. E kore te paninga ārai-waikura polyurea Delsil e pakaru ahakoa he rerekētanga kei roto i te hanganga maitai, ā, ka taea tonu te kapi i te mata katoa o te mea mahi ahakoa i roto i ngā āhuatanga rerekē pērā i ngā piko, ngā hekenga rānei o ngā paipa.
Ngā tikanga hanga
Hangarau Ārai-waikura Hou mō ngā Puna Para
I te mea ka kaha haere te āhua tiaki taiao, ka whakamahia te tikanga kohikohinga pokapū mō ngā wai para ahumahi, ngā wai para hauora, me te maimoatanga wai paru whenua. Kua noho te ārai-waikura o ngā puna kaukau raima, ngā pouaka whakarewa rānei kei roto ngā wai para, ngā wai para rānei hei kaupapa matua. Ki te kore, ka puta he turuturu tuarua o te wai para, ka hua ake he parahanga kore e taea te hoki ki te oneone. E ai ki ngā tatauranga kāore i oti, ko te roa o te ora o ngā puna wai para ārai-waikura he 15 ngā wā i ngā puna wai para kore-waikura. He mārama, ehara i te mea he wāhanga matua o ngā whare tiaki taiao te ārai-waikura o ngā puna wai para, engari he hua huna hoki mō ngā umanga.
- 1. Te huri me te horoi i te rūma o raro: Tuatahi, horoia te puehu, ngā paru hinu, te tote, te waikura, me ngā mea tuku puehu mai i te mata o te rūma. Kia oti te huri, me tango te puehu i roto i te mīhini horoi.
- 2. Paninga paninga kore-whakarewa: Me pani ki te mata o te whenua i mua i te hanganga. Ka taea e ia te hiri i ngā pūwero o te mata o te papa, te whakaiti i ngā hapa o te paninga i muri i te rehu, me te whakanui ake i te piri i waenga i te paninga me te papa sima me te raima. Taria kia maroke rawa i mua i te haere tonu ki te taahiraa e whai ake nei o te hanganga.
- 3. Paparanga whakatika putty Polyurea (kua tīpakohia i runga i ngā āhuatanga o te pakaru): Whakamahia te putty whakapiri polyurea motuhake mō te whakatika me te whakataurite. I muri i te whakamaroke, whakamahia he wira huri hiko mō te huri whānui, kātahi ka horoi i te mīhini horoi.
- 4. Hirihanga paninga kore-whakarewa: Whakaranua te paninga kore-whakarewa me te matū whakaora ki te ōwehenga kua whakaritea, whakaohokia kia ōrite, ka hurihia, ka waruhia rānei te paninga kia ōrite i roto i te wā whakamahinga kua tohua. Hirihia te mata o te turanga, ka whakapiki ake i te piri. Tukua kia maroke mō te 12-24 hāora (i runga i te āhua o te papa, me te kaupapa o te hiri i te papa).
- 5. Rehuhia te paninga ārai-waikura polyurea; I muri i te whakamātautau rehu, rehuhia tuatahi te kōhao hononga, kātahi ka rehuhia te mata o roto o te paipa, ka rehuhia ngā paipa tika, ngā tuke rānei i roto i te wheketere, ā, ka rehuhia ngā hononga ki te wāhi. Rehuhia mai i runga ki raro, kātahi ki raro, ka nekehia ki tētahi wāhi iti i roto i te tauira whakawhiti. Ko te matotoru o te paninga he 1.5-2.0mm. Whakaotia te rehu i te wā kotahi. Kei roto i "Ngā Whakatakotoranga Paninga Hangarau Polyurea" ngā tikanga motuhake.
- 6. Hurihia te paninga me te rehu i te paninga o runga polyurea: Whakaranua te matū matua me te matū whakamaroke ki te ōwehenga kua tohua, whakaohokia kia pai, ka whakamahi i te roera motuhake mō te huri rite, te mīhini rehu rānei hei rehu i te paninga o runga polyurea ki runga i te mata paninga polyurea kua tino whakamaroke. Ātete ki ngā hihi ultraviolet, ārai i te koroheketanga, me te huringa tae.
Te Ārai i te Waikura o ngā Paipa
I ngā tekau tau tata nei, kua tino whanakehia ngā rauemi ārai waikura o ngā paipa. Mai i te pūnaha ārai waikura tāra waro tuatahi ki te pūnaha ārai waikura kirihou 3PE, ā, ināianei ki ngā rauemi hiato polymer, kua tino pai ake te mahi. I tēnei wā, ko te nuinga o ngā tikanga ārai waikura he āhuatanga pēnei i te uauatanga o te hanga, te poto o te roanga o te ora, te uaua o te tiaki i te wāhanga whakamutunga, me te kore e pai ki te taiao. Nā te putanga mai o te polyurea kua whakakīia tēnei āputa i te mara.
- 1. Te pupuhi onepu hei tango i te waikura: Tuatahi, ka pupuhi onepu ngā paipa hei tango i te waikura kia rite ki te paerewa Sa2.5. Me whakaoti te tukanga pupuhi onepu i roto i ngā haora e 6. Kātahi ka pania te paninga polyurethane primer.
- 2. Te paninga o te paninga tuatahi: Whai muri i te pupuhi onepu, ka pania te paninga tuatahi motuhake kāore he whakarewa. Kia maroke te paninga tuatahi ki te āhua kāore he wai e toe ana i runga i te mata, ka rehuhia te paninga polyurethane. Me whakarite kia ōrite te paninga kia mau ai te piri i waenga i te polyurethane me te papa paipa.
- 3. Te rehu polyurethane: Whakamahia he mīhini rehu polyurethane hei rehu i te polyurethane kia ōrite te matotoru o te kiriata. Me maeneene te mata, kāore he rerenga wai, he kōhao iti, he mirumiru, he ngatata rānei. Mō ngā pakaru ā-rohe, ngā kōhao iti rānei, ka taea te whakamahi i te whakatikatika polyurethane ā-ringa hei whakapiripiri.
