Cobalt (II) 2-ethylhexanoate yog cov organic acid hlau xab npum accelerator uas muaj peev xwm ua kom lub decomposition ntawm peroxides (xws li methyl ethyl ketone peroxide MEKP), yog li txhawb nqa cov dawb radical crosslinking curing cov tshuaj tiv thaiv ntawm unsaturated polyester resin (UPR) ntawm chav tsev kub lossis nruab nrab kub.
Cov yam ntxwv ntawm cov khoom tseem ceeb raws li hauv qab no
Kev ua haujlwm zoo catalytic
Cobalt ions, raws li qhov sib txawv ntawm cov hlau valence, tuaj yeem ua rau cov decomposition ntawm peroxides los tsim cov dawb radicals sai heev, txo cov sij hawm kho ntawm resins thiab txhim kho kev tsim khoom.
Tsawg tus nqi ntxiv
Feem ntau, tsuas yog 0.1% -0.7% ntawm cov resin huab hwm coj (xws li cobalt hlau) yuav tsum tau ntxiv kom ua tiav cov txiaj ntsig tseem ceeb, nrog rau kev cuam tshuam me ntsis ntawm lub cev ntawm cov khoom kawg.
Tsawg viscosity, zoo fluidity
Raws li tib qib cobalt cov ntsiab lus, cov khoom no muaj qis dua viscosity thiab zoo dua fluidity, dab tsi ua rau nws yooj yim rau sib tov thiab disperse tusyees nyob rau hauv cov mis.

FAQ
Q: Dab tsi yog qhov txawv ntawm cov cobalt salicylate (cobalt naphthalate) hauv khw?
A: Cov xim ntawm cobalt isooctanoate nws tus kheej yog sib zog dua li ntawm cobalt cycloalkanoate. Rau cov khoom siv xim dawb lossis lub teeb xim (xws li siab-kawg pob zeb thiab cov xim xim xim), nws tuaj yeem txo cov xim daj thiab tsaus nti ntawm cov khoom xim thiab tuav cov xim ntshiab.
Nyob rau tib qhov ntau npaum li cas, nws txoj haujlwm catalytic feem ntau yog siab dua thiab kho sai dua.
Tsawg viscosity, yooj yim dua thiab sib xyaw ua ke hauv cov cob,
Q: Puas yuav ua rau cov nyhuv deteriorate thaum siv rau lub caij ntuj no (tsawg kub ib puag ncig)? Yuav kho li cas?
A: Yog, qhov kub thiab txias yuav cuam tshuam rau nws cov dej num, ua kom cov resin viscosity, txo cov tshuaj tiv thaiv kab mob, thiab txo cov kev txhawb nqa, uas yuav ua rau kev kho tsis tiav thiab cov nplaum nplaum.
Tab sis nws tuaj yeem daws tau los ntawm txoj kev yooj yim.
1. Ua kom ntau npaum li cas kom tsim nyog: Tsis pub dhau qhov tso cai ntawm cov mis, nce qhov ntau npaum li 0.1% -0.2%.
2. Kev sib xyaw ua ke nrog cov khoom siv accelerators: Thaum ua ke nrog me me ntawm cov amine accelerators xws li dimethylaniline, nws tuaj yeem txhim kho qhov qis -kub curing kev ua tau zoo.
3. Preheat raw materials: Before use, place the resin and accelerator in a warm environment (such as>15 ° C) rau lub sijhawm.
