Pūwero Paipa Raina-Rapa Ngaio – Whakaiti Wiri me te Whakatika Ārai-Waku mō ngā Ngongo, ngā Taura me ngā Ngongo
Tirohanga Whānui mō te Rawhi Paipa Rapa
I roto i ngā whakaurunga miihini me ngā whakaurunga paipa, ko te pa o te konganuku ki te konganuku kāore i tiakina he pūtake noa o te pakaru, te haruru, me te pakaru o ngā wāhanga.Rawhi Paipa Raina-Rapahe whakautu māmā engari he tino hangarau. Mā te whakakotahi i tētahi whitiki rino piauau pakari, i tētahi whitiki kowiri tira rānei me tētahi whakaurunga rapa EPDM kua herea, ka hangaia e tēnei rawhi he ārai tiaki i waenganui i te whakapiri me te mea e mau ana. Ehara i te mea ka mau pūmau noa tēnei hoahoa engari ka mimiti kaha hoki i te wiri, ka ārai i te ru, ā, ka ārai i te kino o ngā ngongo, ngā waea, ngā ngongo rānei.
He mea nui tēnei wāhanga i ngā wāhi katoa e tino hiahiatia ana te pono me te roa o te ora o te pūnaha. Mai i te whakahāngai i ngā taura waea i roto i ngā taputapu taumaha ki te whakapūmau i ngā raina whakamatao i roto i ngā pūnaha HVAC, ka whakaratohia e ia te whakapumautanga takirua o te tūnga pumau me te tiaki mata mō te wā roa. Ko te hoahoa o te rawhi he mea nui ki te tāutanga ngāwari, whai hua mō ngā taputapu me te pupuri tonu i te kaha pupuri teitei, ka waiho hei whiringa pono mō te tiaki mara me te hanga taputapu taketake.

Ngā Āhuatanga me ngā Painga o ngā Kīpī Paipa Raina-Rapa
Hoahoa Ārai-Wīwī Rua: Ko te rīpene rapa EPDM whakauru he ārai tino whai hua, he mimiti i te wiri me te whakaiti i te tuku haruru. He mea nui tēnei mō te tiaki i ngā wāhanga tairongo i roto i ngā tono motuka, moana, me ngā mīhini taumaha.
Matua Ātete-Waikura: Kōwhiria mai i tā mātou kōwhiringa Rino Pirau (W1) pakari mō ngā tono paerewa, i te Kowiri tira 304 (W4) kounga teitei rānei mō te ātete pai rawa atu i ngā taiao kino, waikura, me waho rānei.
Āraitanga Pono: He pai rawa te ārai hiko e whakaratohia ana e te arai rapa, e tāpiri ana i tētahi paparanga haumaru nui i te wā e mau ana ngā taura hiko me ngā taura waea.
Te Kaha Whakapūmau: Ko te whitiki maitai kaha-teitei, e whakakahangia ana i te kōhao pūtu, e whakarite ana i te kaha whakapūmau kaha me te pumau e ārai ana i te paheke, i te wetekina rānei i roto i te wā.
Whānuitanga o te Awhe Pāmahana Mahi: He mea hanga ki te EPDM kounga teitei, he pono te mahi a ā mātou rawhi i ngā pāmahana tino kino, mai i te -40°C ki te 120°C, me te kaha ki te tu atu i ngā pikinga poto tae atu ki te 200°C.
Me pēhea te whiriwhiri i te rawhi tika mō tō tono
He māmā noa te whiriwhiri i te whitiki tika ina whakaarohia ēnei āhuatanga matua e toru:
1. Taurite Rauemi: Aromatawaihia tō taiao mahi.
Mō te whakamahinga whānui o roto, mō ngā tono motuka paerewa rānei, he tino pai te mahi a tā mātou W1 (Rino Pirau) utu iti.
Mō ngā taiao moana, mō ngā whare hanga matū, mō ngā whakaurunga o waho rānei e āwangawanga ana mō te waikura, haumi ki te ātete waikura pai rawa atu o tā mātou W4 (Waikura Kowiri tira 304).
2. Whakaritea te Rahi o tō Herenga: Inehia te whānui o waho o te paipa, te whānui katoa rānei o te paihere taura e hiahiatia ana e koe hei whakau. Tīpakohia te rahi o te herenga mai i te ripanga i runga ake nei e rite ana ki tēnei inenga.
3. Kōwhiria te Āhua Tika: Ahakoa kei a mātou ā mātou āhua momo-R me te momo-U rongonui (pātai atu mō te āhuahanga motuhake), ko te whiriwhiri taketake o te rauemi me te diameter te tīmatanga mō te tāutanga angitu.
