(1) Cov duab kos emulsion roj pas dej yog qhov me me, cov yeeb nkab xa rov qab yog luv thiab kaw, ua rau qeeb cua sov dissipation, ua rau cov roj emulsion kub.
(2) Copper hlau annealing ua rau blackening ntawm cov xim.Ua ntej, txawm tias rub rov qab cov dej txias feem ntau yog siv cov kais dej, dej hauv av, vim tias cov dej tsis zoo tsis zoo ib yam nyob txhua qhov chaw, qee qhov chaw ntawm cov dej tsis zoo PH tus nqi qis, tsuas yog 5.5 ~ 5.0 (ib txwm yog 7.0 ~ 7.5), qhov thawj emulsion nyob rau hauv cov yeeb yaj kiab antioxidant raug ntxuav tawm, qhov annealing ntawm tooj liab hlau yog yooj yim rau oxidize, blackened;Thib ob, nyob rau hauv lub tshuab nqus hlau zoo tib yam rub cov khoom tiav ntawm cov hlau tooj liab hauv cov kab annealing nyob rau hauv lwm txoj kab annealing, cov dej txias kuj tsis siv cov tshuaj tua kab mob antioxidant, lub sij hawm antioxidant luv luv, yuav sai sai no oxidized dub tshwm sim;
(3) Qee lub tsev qub qub tseem siv lub tog raj kheej annealing rau anneal.Tnws cov laj thawj hauv qab no kuj tseem yuav ua rau oxidation, blackening: Ua ntej, lub tog raj kheej annealing tsis nruj, yaug cov pa roj carbon dioxide los yog high-purity nitrogen to;Qhov thib ob, tawm ntawm lub tog raj kheej ntawm cov tooj liab hlau yog qhov kub thiab txias, siab tshaj 30 ° C;Thib peb, cov hlau kos duab emulsion txij nkawm tsis txaus, tus nqi PH tsawg dhau;cov rooj plaub no muaj ntau dua nyob rau lub caij ntuj sov thaum qhov kub thiab txias, cov emulsion yuav siv tau yam tsis muaj kev txwv tsis pub poob ntawm qhov kub thiab txias, ces poob sai dua.Thaum qhov kub thiab txias, qhov poob yog sai dua, yog tias koj tsis ntxiv cov roj av tshiab raws sijhawm, cov roj cov ntsiab lus tsawg heev nyob rau lub sijhawm no, nrog rau qhov kub thiab txias, qhov kub ntawm cov emulsion yuav ntau dua 45. ℃, nws yooj yim ua rau oxidation thiab blackening.
(4)ATsis muaj qhov xwm txheej yog tias, vim tias tam sim no siv dav hauv kev siv hluav taws xob nrawm nrawm, nws qhov nrawm nce, lub sijhawm sib txheeb ntawm cov cua sov dissipation raug txo, mus rau oxidation ntawm qee qhov chaw thiab lub sijhawm, yog li nws pom zoo kom cov tuam txhab them nyiaj ntau dua. saib xyuas cov roj cov ntsiab lus ntawm qhov xwm txheej emulsion, kev siv qhov kub thiab txias, PH nqi, thiab lwm yam. Txawm hais tias nws tsim nyog los siv cov xim daj pwm los nag rau lub caij nplooj ntoos hlav, cov kab mob tua kab mob ceev ceev, koj tuaj yeem siv cov tshuaj tua kab mob fungicidal, muaj nyob rau lub caij ntuj sov antioxidant los daws qhov teeb meem ntawm oxidation, Blackening teeb meem yuav tsis muaj teeb meem.
