Whakamahinga
He matū waro te 4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA), ā, ko ōna huarahi tono matua koia ēnei:
- Te Hanganga o ngā Rauemi Polyurethane: He mea nui te MOCA hei whakaroa mekameka mō ngā elastomers polyurethane. I roto i te hanga polyurethane, me tauhohe ngā prepolymers isocyanate ki ngā whakaroa mekameka hei hanga i ngā polymers polyurethane taumaha-ngota teitei. He tino teitei te tauhohenga o te MOCA ki ngā isocyanates, ka taea te whakaroa i te mekameka ngota polyurethane me te whakapai ake i te pakeke, te kaha, te ātete kakahu, te ātete haehae me ētahi atu āhuatanga o te rauemi. He mea whakamahi noa i roto i te hanga i ngā hua elastomer polyurethane kawenga-teitei, pērā i ngā pereti tatari, ngā roera rapa, ngā hiri, me ētahi atu e whakamahia ana i roto i ngā ahumahi pēnei i te keri maina, te whakarewa, me te hinu. Me pai te ātete kakahu me ngā āhuatanga miihini o ēnei hua.
- Māngai Whakaora mō ngā Kapia Epoxy: Ka taea te whakamahi i te MOCA hei māngai whakaora mō ngā kapia epoxy. Ka pāngia e te tauhohenga whakawhiti-hononga me ngā kapia epoxy hei hanga i tētahi hanganga whatunga toru-ahu, ā, ka whakaora i ngā kapia epoxy. He pai ngā āhuatanga miihini, te ātete matū ki te waikura, me te ātete wera o ngā kapia epoxy kua whakaorahia. He maha ngā wā ka whakamahia i roto i te hanga i ētahi rauemi epoxy me ngā whakaritenga mahi teitei, pērā i ngā mara o ngā rauemi kohua hiko me ngā paninga papa. Me tiaki e ngā rauemi kohua hiko ngā wāhanga hiko o roto mai i te taiao o waho. Ka taea e te kapia epoxy kua whakaorahia me te whai wāhi mai o te MOCA te whakarato i te hiri pai me te tiaki miihini. Me whai āhuatanga ngā paninga papa epoxy pērā i te ātete kakahu me te ātete waikura kia tutuki ai ngā whakaritenga whakamahinga o ngā wāhi pērā i ngā awheawhe ahumahi me ngā papa waka.
Te Tākai me te Tukunga
25KG/pēke, kia rite rānei ki ngā whakaritenga a te kiritaki.
Tukunga: 6.1 momo taonga morearea, ā, ka taea te tuku mā te moana.
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
