Ko te waikawa 2,2-Dimethylolbutanoic (DMBA) he waikawa neopentyl carboxylic me ngā rōpū hydroxymethyl tauhohe e rua, nō reira ka taea te whakamahi hei pūnaha polymer wai-hangai, ā, e whakamahia whānuitia ana i roto i te pūnaha polyurethane wai-rewa, polyester me te epoxy resin.
He pai ake te wairewa o te DMBA i DMPA i roto i ngā whakarewa rerekē, nō reira ka taea te whakapai ake i te whai huatanga o te mahi.
E kiia ana a DMBA he whakatupuranga hou o te whakaroa mekameka matomato, ā-taiao hoki, me te emulsifier ā-roto mō te polyurethane wai-pūtake; Ka taea te whakamahi i roto i te hanga piri polyurethane wai, me te kore e whakamahi i ngā whakarewa waro, ā, kāore he toenga waro e tukuna ana. Ka whakaoti i ngā hapa o DMPA pērā i te ira rewa teitei, te puhoi o te whakarewatanga, te roa o te wā tauhohenga, te nui o te whakapaunga pūngao, te ngoikore o te mahi hua, te hiahia mō ngā whakarewa waro, te nui o te toenga o te whakarewa me ētahi atu.
Ka taea hoki te whakamahi mō te hanga i te kapia epoxy wai-ā-wai me ngā piripiri polyester.
I tēnei wā, koinei te taputapu āwhina whakarerekētanga maha-mahi pai rawa atu (whakaroa mekameka hydrophilic) o te polyurethane, ngā kapia wai-tū, ngā piripiri wai-tū, ngā peita wai-tū me ētahi atu hua wai-tū; hei monomer mō te tukanga whakarerekētanga, kāore e hiahiatia he wai hei whakarewa rauropi (hei utu mō te waikawa Dimethylolbutanoic (DMBA), nō reira he māmā ake te tukanga whakaputa, ā, he pumau ake, he pai ake hoki te mahi. Ina koa, DMPA(waikawa dimethylolpropionic) kua riro hei hua rongonui i te ao wai-pūtake mō te utu pai rawa atu!
25kg/pēke; pēke kiriata kirihou konumohe kua whakakikoruatia ki te pahu kātene, ki te kātene rānei. 25kg/pahu.
