DMCHA ke eng?
Sebopeho sa Lik'hemik'hale
DMCHA e bolela N,N-Dimethylcyclohexylamine. Ke karolo ea sehlopha sa li-catalyst tsa amine tse sebelisetsoang ho etsa polyurethane. DMCHA e na le lesale la cyclohexyl le kopantsoeng le sehlopha sa dimethylamine. Setha sena se fa DMCHA likarolo tse ikhethang tsa lik'hemik'hale 'me se thusa ho sebetsa e le li-catalyst.
Baetsi ba di-formula le bareki ba tsotella foromo le boima ba dimolek'hule tsa DMCHA. O ka bona dintlha tsena tafoleng e ka tlase:
| Foromo ea limolek'hule | Boima ba limolek'hule |

Lesale la cyclohexyl le leholo mme le ama tsela eo DMCHA e leng ya motheo le e arabelang ka yona. Sehlopha sa dimethylamine se thusa DMCHA ho sebetsa e le motheo. Dikarolo tsena mmoho di etsa hore DMCHA e be sesosa se setle sa dikarabelo tsa polyurethane. Ho sebedisa dmcha e hlwekileng haholo ho thusa difeme ho fumana diphetho tse tsitsitseng.
Karolo ho Li-Catalyst tsa Polyurethane Amine
DMCHA e bohlokoa haholo ho etseng polyurethane. E sebetsa e le catalyst mme e etsa hore karabelo lipakeng tsa polyols le isocyanate e potlake. Ts'ebetso ena e na le mehato e 'maloa:
Ts'ebetso ena e thusa ho leka-lekanya liketso tsa gelling le blowing. DMCHA e thusa ho etsa hore libopeho tsa sele li be tse lekanang ka har'a foam e thata. E boetse e nolofatsa ts'ebetso mme e fana ka boleng bo tsitsitseng ba foam.
Keletso: Ho eketsa dmcha ho polyurethane ho ka etsa hore foam e be betere mme ha boloka nako.
Sebopeho sa DMCHA le tsela eo e sebetsang ka yona di etsa hore e ratoe ke baetsi ba bangata. E fana ka ts'ebetso e matla mme e thusa ho etsa thepa e thata, ya boleng bo hodimo.
