Amine Tauhohenga Matatau mō ngā Pūnaha Tukunga-Iti
He whakakorikori wai kounga teitei te MXC-DPA i hangaia hei whakateretere i te whakamaroke i roto i ngā momo tono PU.
He whakakorikori amine tuatoru tauhohenga teitei te MXC-DPA i hangaia hei whakatutuki i ngā paerewa tukunga VOC tino pakari i roto i te umanga polyurethane:
-
Hanganga Hydroxyl Tauhohe:He rerekē ki ngā whakakorikori tuku iho, kei roto i te MXC-DPA ngā rōpū hydroxyl tauhohe e hono matū ana ki te matrix polymer PU, e kore ai e heke te kaha, ā, he iti tonu te haunga o te matū.
-
Te Tika o te Ngārara:Me te taumaha ngota o$218.34$ā, he hanganga mahi-rua, ka whakaratohia he kōtaha tauhohenga pumau, taurite hoki e tika ana mō ngā pahuka whakarewa kounga teitei, ngāwari hoki.
Te Whai Hua o te Whakakorikori me te Mahi Pahuka
Hanganga ngota o te MXC-DPA (CAS 63469-23-8), he whakakorikori amine tauhohe pai rawa atu mō ngā pūnaha PU iti-tukunga.
Mō ngā kaihangarau whakaputa, ko te āhua matū ahurei o MXC-DPA ka hua ake he mana tukatuka pai rawa atu me te kounga o te hua whakamutunga:
-
Te Whakapūmau me te Pupuhi Taurite:He taurite whakakorikori maha ōna e whakatairanga ana i te hanganga mirumiru me te tipu pūhui, e ārai ana i te hinganga o te pahuka o roto, i ngā rerekētanga mātotoru rānei.
-
I arotauhia mō te RIM me te pahuka ngāwari:Nā te kaha tauhohenga motuhake o te MXC-DPA, he mea tino pai mō te Whakakikorua Injection Molding (RIM) me ngā tono nohoanga motuka matatau e tino hiahiatia ana te hanganga tika.
-
Te Whakapai Ake i te Āhua o te Pūtau:Mā te whakahaere i te tere o te tauhohenga, ka āwhina i te waihanga i tētahi hanganga pūtau tuwhera, ōrite ake, ka whakarei ake i te manawa me te whakamarie o ngā pahuka polyether ngāwari.
Haumaru Tukanga me ngā Painga o te Mekameka Tuku
Ka whakaratohia e mātou ngā raraunga hangarau mārama hei āwhina i ngā kaiwhakahaere hoko ki te whakaiti i te mōrearea me te whakapai ake i te whai huatanga o te hanga:
-
Te Haumaru o te Pūwāhi Uira-Tiketike:Me te ira mura o te 90°C me te ira koropupū o te 212°C, ka nui ake te pumau o te wera o te MXC-DPA i ngā mea pūngāwerewere kē atu, ka whakaiti i te mōrearea ahi i roto i te wheketere.
-
Te Whakaranu me te Ngāwari ki te Whakahaere:Ka hono pai te wai matotoru iti ki te nuinga o ngā polyol me ngā tāpiringa, kia tika ai te inenga me te ārai i ngā ārai taputapu i roto i ngā raina whakaputa aunoa.
-
He iti te wai kua whakamanahia:Mā tā mātou mana whakahaere kounga tino kaha ka mau tonu te nui o te wai i raro i te 1%, ka ārai i te pokanoa ki te tauhohenga isocyanate, ā, ka whakarite hoki i te ōrite o te matotoru o te pahuka puta noa i ia puranga.
