I te whai a te umanga hangahanga o te ao kia pai ake te mahi, kia pai ake te utu, me ngā otinga e pai ake ana ki te taiao, kei te huri marietia te āhua o te umanga polyurethane e tētahi takawaenga matū matua.Anhydride Dimethylthioterephthalic, e whakarāpopototia ana ko DMTDA (nama CAS: 106264-79-3), hei kaihoko whakaora wai hou, kei te whakarato ki ngā kaihanga o Āhia ki te Tonga-mā-rāwhiti me Amerika ki te Raki he huarahi pai ake e hipa ana i ngā rauemi tuku iho i runga i te mahi.
I. Te Whakahou i ngā Paerewa Mahi: Ngā Painga Matua o te DMTDA
Ehara te DMTDA i te whakakapinga noa iho; he otinga whakapai ake i te mahi. Ki te whakatauritea ki te matū whakamaroke totoka tuku iho MOCA, kua eke te DMTDA ki te hiranga whānui o te āhua ā-tinana, te ngāwari o te mahi, me te mahi hua whakamutunga.
Ngā Whakatakotoranga Hangarau Matua:
Ingoa Hua: Dimethyl Thio-Toluene Diamine (DMTDA)
Tau CAS:106264-79-3
Tātai ngota:C9H14N2S2
Āhua:Wai Mārama Kōwhai Mā
Te Parakore:≥95% (Te Ihirangi Amine Katoa)
Mahi:Whakaroa mekameka / Kaiwhakaora / Kaiwhakawhitiwhiti
Mā te hanganga matū o te DMTDA ka taea e ia te mahi hei hononga whakawhiti whai hua, e whakarato ana i ngā āhuatanga miihini tino pai ki te hua pūmua whakamutunga. Nā tōna āhua wai ka kore e hiahiatia te whakamahana, te whakarewa rānei i mua i te whakamahinga, he mea e hiahiatia ana mō ngā matū whakaora totoka pēnei i te MOCA, ā, nā reira ka penapenahia te pūngao me te whakapai ake i te haumaru o te wāhi mahi.
II. He aha i whiriwhiri ai i te DMTDA? Te nekenga mai i te MOCA
He ngāwari te whakahaere, he ruarua te whai huatanga
Wai i te pāmahana rūma: Ka puta te DMTDA hei wai matotoru kōwhai mā i te pāmahana rūma, ka kore e hiahiatia te tukanga rewa uaua pērā i te MOCA. Ehara i te mea ka penapena noa i te pūngao me te haumi taputapu engari ka māmā ake hoki te tukanga whakaputa, ka tino whakarei ake i te pai o te whakaputa.
He iti te matotoru, he ngāwari te whakaranu: Mā te iti o te matotoru ka tere te whakaranu me te ōrite o te prepolymer, he mea tino pai mō ngā tukanga matatau pēnei i te werohanga tauhohenga me te rehu i ngā elastomers polyurea e hiahia ana kia nui te pai o te whakaranu.
He tino pai te ōhanga, he painga nui ki te utu
He iti ake te horopeta: He iti ake te matū ōrite o te DMTDA i te MOCA, ā, e taea ai te whakaiti i te whakamahinga rauemi tata ki te 20% i roto i ngā mahi tūturu. Ko te tikanga o tēnei ko te whakatutuki i te mahi ōrite, pai ake rānei, me te whakaiti tika i ngā utu rauemi mata.
Utu pumau: Nā ngā tukanga whakaputa pakeke me ngā pānga tauine,te utu o te DMTDAe mau tonu ana te pumau, e whakarato ana i te taurangi pono mō te whakahaere utu mo te wa roa mo nga umanga.
Kounga pai ake: Ngā āhuatanga ā-tinana tino pai: Ko te elastomer polyurethane i whakamaroketia ki te DMTDA he pai ake i te pūnaha MOCA i roto i ngā tohu matua pēnei i te pakari, te ātete ki te kakahu, me te ātete ki te pakaru piko. Mā tēnei ka roa ake te hua whakamutunga, ā, ka taea hoki te tu atu i ngā āhuatanga uaua ake.
Whānui te whakamahinga: Mai i ngā roera tā mahi-teitei, ngā wāhanga motuka, ki ngā paninga ātete ahi, ngā rauemi ātete-waikura whakarewa, kei te whānui haere tonu ngā whakamahinga a DMTDA, e whakarato ana i te kaha ki te whakapai ake i ngā hua i roto i ngā momo ahumahi.
Haumaru, ā, he pai mō te taiao, e rite ana ki ngā au o te ao
He iti te paitini, he haumaru: Ko te paitini oDMTDAhe iti iho i tērā o te MOCA, ā, kāore he mōrearea whakaputa mate pukupuku, whakaputa whakarerekētanga rānei, e whakapai ake ana i te taiao whakaputa me te whakarite i te hauora o ngā kaiwhakahaere, e āhei ai ngā umanga ki te whai ngāwari i ngā ture hauora me te haumaru mahi e kaha haere ana te kaha.
III. Tukanga hoahoa taiao
Ko te tukanga whakaputa e whakamahi ana i te "tikanga whakangao kūpapa" e whai hua ake ana, e pai ake ana hoki mō te taiao, e hangai ana ki te ia o te ao mō te hanga matomato.
Te Whakauru Hōhonu ki Āhia ki te Tonga-mā-rāwhiti me Amerika ki te Raki: Te Hopu i te Manawa o te Mākete
Ahakoa he rerekē ngā wāhanga whanaketanga o ngā mākete o Āhia ki te Tonga-mā-rāwhiti me Amerika ki te Raki, he nui te hiahia mō ngā otinga rauemi mahi-teitei me te whai hua-teitei i waenganui i a rāua.
Mākete o Āhia ki te Tonga-mā-rāwhiti: Te pikinga o ngā hanganga me ngā mahi hanga
Ngā ngaru hanga whare matomato: I te tere haere o te noho tāone i ngā whenua o te Tonga-mā-rāwhiti o Āhia, kua piki ake te hiahia mō ngā rauemi hanga whare mahi-teitei. Ko te whakamahinga o te DMTDA i roto i ngā paninga ātete ahi me ngā mara ārai-waikura whakarewa e tino tutuki ana i ngā paerewa teitei o te haumaru me te pakari o te hanga whare e hiahiatia ana e tēnei mākete.
IV. Whakapai ake i te hanga
Hei whenua nui mō te whakawhiti hangahanga o te ao, kei te tere haere te whanaketanga o ngā ahumahi motuka, kakahu, me te pepa o Āhia ki te Tonga-Rawhiti. Mā te whakamahinga o te DMTDA i roto i ngā mara hangahanga teitei pēnei i ngā wāhanga motuka me ngā roera tā ka taea te āwhina i ngā umanga ā-rohe ki te whakarei ake i te whakataetae hua me te hopu i te mekameka uara teitei.
Mākete o Amerika Te Raki: Te auahatanga hangarau me te hangahanga teitei
Kaiwhakaoho mō ngā tukanga matatau: Ko te mākete o Amerika Te Raki te kaiārahi i roto i ngā hangarau matatau pēnei i te werohanga tauhohenga me te rehu o ngā elastomers polyurea. Hei kaihoko whakaora wai tino pai,DMTDAka taea te whakamahi katoa i ngā painga o ēnei tukanga me te akiaki i ngā auahatanga hangarau i roto i ngā wāhanga pēnei i te whakamama i ngā waka me ngā paninga tiaki mahi-teitei.
