Kuwuma kwa infrared kumathaSinthani magwiridwe antchito a Twin-screwder chifukwa imachepetsa kuchepa kwa mtengo wa IV ndikuwongolera kwambiri kukhazikika kwa ntchito yonseyo.
Choyamba, regrind regrind idzakhala yolima ndikuwuma pafupifupi mphindi 15-20 mkati mwa ziweto. Kulira uku ndi kuyanika kumatheka ndi njira yotentha yothandizira pogwiritsa ntchito radiation kuti mukwaniritse kutentha kwa 170 c. Poyerekeza ndi njira yotentha yapansi, mpweya wambiri komanso wowongolera umathandizira kuti muthe kusintha chinyezi m'njira chinyezi - njira zowongolera radiation zitha kuyankha pakusintha mikhalidwe yamasekondi. Mwanjira imeneyi, mtengo womwe uli mu 5,000 mpaka 8,000 ppm mkati mwa chiberekero ndi chochepetsera chinyezi chotsalira cha pafupifupi 150-200 ppm.
Monga chinthu chachiwiri cha njira ya Crystallization ku Ird, kachulukidwe kambiri ka zinthu zophwanyika zimawonjezeka, makamaka popepuka kwambiri. Munjira imeneyi:IRD imatha kuwonjezera kuchuluka kwa kuchuluka kwa 10% mpaka 20%, yomwe ingaoneke ngati kusiyana kochepa kwambiri, koma imatha kusintha mwachangu poyambira - ngakhale kuthamanga kwa extrider kumakhalabe komweko.
Monga njira ina yotentha kwambiri kutentha komanso makina owuma, makina a ird amathanso kupanga chowuma mwachangu kuti mugwiritse ntchito moyenera komanso kutentha kouma pansi pa 120 ° C. Pankhaniyi, zokhutira zinyozo zimatheka kuti "pokhapokha" pafupifupi 2,300 ppm, koma mwanjira imeneyi zitha kusungidwa modalirika, makamaka mkati mwazinthu zomwe zimatchulidwa ndi wopanga matope. China chofunikira kwambiri ndi kupewa kusinthasintha kwapamwamba komanso kosatha kwa phindu, ndikuchepetsa chinyontho mpaka 0.6% yomwe imachepetsa gawo la IV mu pulasitiki yosungunula. Nthawi yokhazikika mu chowuma zitha kuchepetsedwa mpaka mphindi 8.5 ndipo kugwiritsa ntchito mphamvu kumakhala kochepera 80 w / kg / h
