Mahinga Hua:
He rā white (mākū) ranei paura (maroke), koreami, akeake, me te nontoxic. Ko te thixotrope ki te pūāhua o wāhanga nui te viivii, tioata, GELATION pai, me te taonga Shade kaha.
Ko reira he sima o te whakakōkī hangai mo āhua-waihanga onge-whenua Y tatari rāpoi, he sima i roto i te konumohe magnesium muka tutu, he whākōkī i roto i te hanga ethylene i waipiro maroketanga me i roto i te hanga epoxy ewaro. Te reira i taea te whakamahi hoki rite rauemi raw mō te alumina whakahohe me ētahi atu aluminates.
Pseudoboehmite Taupānga:
1. fcc me hydrogenation whakakōkī kawe.
2. sima i roto i te konumohe magnesium muka whakangutungutu.
3. Catalyst i roto i te hanga ethylene i waipiro maroketanga me i roto i te hanga epoxy ewaro.
4. Whakamahia rite rauemi raw mō te alumina whakahohe me ētahi atu aluminates.
