Kua roa te umanga polyurethane e whakawhirinaki ana ki ngā whakakorikori tine nā te mea he whai hua tā rātou mahi ki te whakatere i ngā tauhohenga me ngā tukanga whakamaroke. Heoi, nā ngā āwangawanga mō te taiao me te hauora i akiaki te rapu i ngā huarahi kē atu. Ko tētahi whakakapinga whai hua koMXC-B20, he whakakorikori bismuth carboxylate e tuku ana i ngā painga maha atu i ngā whakakorikori tuku iho he tine.
He aha ai me whakaaro ki ngā huarahi kē atu hei whakakapi i ngā kaiwhakaoho tine?
Kua whānuitia te whakamahinga o ngā whakakorikori kei roto i te tine, pērā i te dibutyltin dilaurate (DBTDL) me te stannous octoate, i roto i te hanga polyurethane. Ahakoa tō rātou whai huatanga, he nui ngā tūponotanga taiao me te hauora o ēnei whakakorikori. Ka taea e rātou te paitini, ā, he maha ngā wā e hono ana ki ngā here ture, nā reira he mea nui kia tūhuratia e ngā kaihanga ngā kōwhiringa haumaru ake.
MXC-B20: He Kāporeitara BismuthKaiwhakaoho
He whakakorikori bismuth carboxylate auaha te MXC-B20, i hangaia hei whakatika i ngā ngoikoretanga o ngā whakakorikori tine. Ka mahi tēnei whakakorikori hei whakakorikori tahi me ngā amine tuatoru, hei whakarei ake i ngā tauhohenga polyurethane me ngā tukanga whakamaroke. Kei konei'kia tirohia tata atu ngā mea e pai ake ai te MXC-B20 hei kōwhiringa:
1. Te Aroha ki te Taiao:
Kāore he matū kino i roto i te MXC-B20 pērā i te waikawa 2-ethylhexanoic (2-EHA), te dibutyltin (DBT), me te tributyltin (TBT). Nā tēnei he kōwhiringa pai ake mō te taiao ki te whakatauritea ki ngā whakakorikori tine tuku iho, e hangai ana ki te pikinga ake o ngā tono ture me ngā tono mākete mō ngā hanganga matū haumaru ake.
2. Te Whakarei Ake i te Mahi:
I ngā horopeta iti, ka whakanuia e te MXC-B20 te matotoru o mua o ngā ranunga polyurethane, ā, ka roa ake te wā whakaroa. He tino whai hua tēnei āhuatanga nā te mea ka taea te whakahaere pai ake i ngā wāhanga tukatuka tuatahi, me te whakarite hoki i te pai o te whakamaroke i muri.
3. Ngā mahi maha:
He hototahi tēnei whakakorikori ki ngā polyol pahuka mārō me ngā polyol pahuka ngohengohe noa, ā, he pai mō ngā momo tono polyurethane. Ahakoa he pahuka poraka ngāwari, he pahuka ngāwari kiato teitei, he pahuka rehu, he pahuka moroiti, he pūnaha pahuka mārō rānei, he whakakorikori maha-whakamahinga, he whai hua hoki a MXC-B20.
4. He Huarahi Kore-Tīni:
Mā te whakakapi i ngā whakakorikori tine ki te MXC-B20, ka taea e ngā kaihanga te whakaiti i te tapuwae taiao o ā rātou hua. Ka whakaitihia hoki e tēnei huarahi kore-tine te mōrearea o te paitini, ka whakatairanga i tētahi wāhi mahi me te hua whakamutunga haumaru ake.
5. Ngā Hua e rite ana, e pai ake ana rānei:
Ahakoa te korenga o te tine, kāore a MXC-B20 e whakaiti i te mahi. Nā tōna kaha ki te mahi hei co-catalyst me ngā amine tuatoru ka whakarite kia whai hua, kia whai hua hoki te tukanga whakamaroke, ā, he maha ngā wā ka puta he hua e rite ana, e pai ake rānei i ērā i tutukihia me ngā catalysts tine-based.
Whakamutunga
Ko te nekehanga ki ngā whakakorikori haumaru ake, ā, he pai ake hoki mō te taiao, he ia o ngā āhuatanga nui o te umanga polyurethane. Ko te MXC-B20, me ōna āhuatanga ahurei me ōna painga, ka puta hei huarahi kē atu ki ngā whakakorikori tuku iho he tine. Nā tōna hototahitanga ki te whānuitanga o ngā polyol, me tōna mahi whakarei ake me ōna tohu taiao, ka waiho hei whiringa pai mō ngā kaihanga e rapu ana ki te auaha me te whakapai ake i ā rātou hua polyurethane. Ko te awhi i te MXC-B20 ehara i te mea e hangai ana ki ngā whakaritenga ture anake, engari e whakatairanga ana hoki i te pumau me te haumaru i roto i te hanga polyurethane.
