(1) Thaj chaw pas dej roj emulsion uas kos duab me me, cov yeeb nkab rov qab luv thiab kaw, ua rau cov cua sov qeeb qeeb, ua rau cov roj emulsion kub siab.
(2) Cov hlau tooj liab annealing ua rau cov xim dub. Ua ntej, txawm tias rub rov qab dej txias feem ntau siv dej kais, dej hauv av, vim tias qhov zoo ntawm dej tsis zoo ib yam txhua qhov chaw, qee qhov chaw ntawm qhov zoo ntawm dej PH tus nqi qis, tsuas yog 5.5 ~ 5.0 (ib txwm yog 7.0 ~ 7.5), cov emulsion qub hauv zaj duab xis antioxidant raug ntxuav tawm, qhov annealing ntawm cov hlau tooj liab yog yooj yim rau oxidize, dub; Qhov thib ob, hauv lub tshuab kos duab hlau ib txwm rub cov khoom tiav ntawm cov hlau tooj liab hauv kab annealing hauv lwm kab annealing, dej txias kuj tsis siv antioxidants, lub sijhawm antioxidant luv luv, yuav sai sai no muaj qhov tshwm sim dub oxidized;
(3) Qee lub Hoobkas qub tseem siv cov thooj voos kheej kheej annealing los ua anneal.TCov laj thawj hauv qab no kuj yuav ua rau oxidation thiab blackening: Ua ntej, lub txiv ntoo annealing tsis nruj, flushing carbon dioxide lossis high-purity nitrogen to; Qhov thib ob, tawm ntawm lub tog raj kheej ntawm cov hlau tooj liab kub dhau, tshaj 30 ° C; Qhov thib peb, kev saib xyuas emulsion tsis txaus, tus nqi PH qis dhau; cov xwm txheej no feem ntau tshwm sim thaum lub caij ntuj sov thaum qhov kub siab, cov emulsion yuav siv yam tsis tau nres qhov poob ntawm qhov kub siab, tom qab ntawd poob sai dua. Thaum qhov kub siab, qhov poob sai dua, yog tias koj tsis rov ua kom cov roj nyoos tshiab raws sijhawm, cov rog muaj tsawg heev lub sijhawm no, ua ke nrog qhov kub siab, qhov kub ntawm emulsion yuav ntau dua 45 ℃, nws yooj yim ua rau oxidation thiab blackening.
(4)Alwm qhov xwm txheej yog tias, vim yog kev siv dav dav ntawm kev kos duab ceev ceev, nws qhov ceev nce ntxiv, lub sijhawm cua sov sib piv txo qis, rau qhov oxidation ntawm qee qhov chaw thiab lub sijhawm, yog li ntawd, nws raug pom zoo kom cov chaw tsim khoom them sai sai rau cov rog ntawm cov xwm txheej emulsion, kev siv kub, PH tus nqi, thiab lwm yam. Txawm hais tias nws tsim nyog siv lub caij ntuj nag daj pwm thaum lub caij nplooj ntoo hlav, kev tsim cov kab mob ntawm qhov ceev ceev, koj tuaj yeem siv cov neeg sawv cev fungicidal antifungal, muaj nyob rau lub caij ntuj sov antioxidant los daws qhov teeb meem ntawm oxidation, Blackening teeb meem yuav tsis yog teeb meem.
