Whakakōkī Whakawhāiti Matatau mō ngā Pūnaha PIR Ārai-Mumura
Ko te MXC-15 (Potassium Octoate Solution) he whakakorikori whakarewa carboxylate kounga teitei, tino motuhake. I hangaia kia whakakorikorihia te whakakorikori o ngā isocyanates, koinei te paerewa ahumahi mō te hanga pahuka pakari polyisocyanurate (PIR) e hiahia ana ki te whakamarumaru wera tino pai, te hanganga hanganga teitei, me te tutuki i ngā whakaritenga haumaru ahi.
Te Hanganga Ngota me te Matua Whakakotahitanga
Ko te hoahoa matū taketake o MXC-15 he mea hanga hei hanga i ngā whatunga pūmua pakari, ātete-wera hoki:
-
Te Whakakotahitanga e Ārahihia ana e te Pāhare Pāhare:He rerekē tēnei i ngā whakakorikori amine paerewa, ko te matua pāhare pāporo tino kaha te mahi motuhake ki te whakatairanga i te hanganga o ngā mowhiti isocyanurate pumau, e whakarerekē ana, e whakapakari ana hoki i te hanganga pūmua.
-
Kaikawe DEG Tauhohe:Ka whakaranua ki te Diethylene Glycol (DEG), ka mau tonu tōna āhua wai pumau, ko te DEG ia e mahi ana hei wai whakaranu tauhohe, e herea ana e te matū ki roto i te whatunga polyurethane me te kore e heke, e kore hoki e pirau mō te wā roa.
Te Haumaru Ahi me te Mahi Ārai Wera
Mō ngā kaihanga rauemi hanga me te whakamarumaru arumoni, ka whakatauhia e MXC-15 te wero nui o te whakatutuki i ngā ture mura o te ao:
-
Ātete Mura Pai Rawa:Ko te whatunga polyisocyanurate matotoru (PIR) i hangaia e tēnei whakakorikori he ātete wera tino pai, e whakapai ake ana i te whakarōpūtanga haumaru ahi o ō panera whakamahana pakari.
-
Te Pūmautanga Ahu Whakarei Ake:Ka whakarite i te āhua pūtau honohono-maha, ōrite hoki. Ka ārai tēnei i te mimiti o te pahuka, ā, ka whakarato i te kaha pēhi tino pai mō te wā roa ahakoa ngā piki me ngā heke o te pāmahana.
Te Whai Hua o te Tukanga me te Mana Whakatakoto
Ka whakatairangahia e mātou ngā tawhā kounga tino pakari kia taea ai te whakarite i te mahi matapae me te whakaurunga maeneene ki roto i ō mahi hangahanga nui:
-
Ngā Arotautanga Wai Kua Arotauhia:He wai mārama ki te kōwhai mārama te hanganga, he matotoru te whakahaere (Mōrahi 6000 cps i te 25°C), ā, ka taea te papu ngāwari me te ine tika i roto i ngā mīhini whakarewa tere-tiketike.
-
Kōtaha Tauhohenga Pūmau:Mā te kōtaha kawakore e tino whakahaeretia ana (pH Min. 9.0) me te ihirangi wai tino pai (3.1-3.5%), ka tukuna he wā pikinga tino ōrite me ngā kōtaha whakamaroke e taea te matapae, kia kore ai e whakaroa i te whakaputanga utu nui.
-
Te Mahi Tahi o te Amine:He tino pai te mahi tahi me ngā kaiwhakakōkī amine tuatoru paerewa, e hoatu ana ki ngā tohunga hangarau te ngāwari tino pai ki te whakatikatika i te taurite i waenga i te whakawhānui pahuka tuatahi me ngā wāhanga honohono whakamutunga.
