M'zaka zaposachedwa, pali makina osokoneza bongo ambiri akhazikitsidwa pamsika ngati njira ina imodzi - screw omasulira ndi makina owuma. (Apa tikuchitcha dongosolo lokhala ndi mitundu yambiri kuphatikiza ma twin-scrept, planetary roller Exller Etc.)

Koma tikuganiza kuti ndikofunikira kuti mukhale ndi makina owuma musanagwiritse ntchito mafuta ambiri. Chifukwa:

1) Makina Osiyanasiyana Amtundu wambiri ali ndi njira zovuta kwambiri zomwe zimakhazikitsidwa pakuletsa hydrolysis zotsatira zakumwa zomwe sizikuwoneka bwino. Nthawi zambiri zimakhala zodziwika bwino pogwiritsa ntchito mkhalidwe:

Zizindikiro zovomerezeka zovomerezeka siziyenera kukhala zapamwamba kuposa 3000 ppm (0.3%)

M'malo mwake, mabotolo a botolo amawonetsa zosiyana, kukula kwa tinthu, tinthu kukula kwake, tinthu tating'onoting'ono komanso makulidwe - komanso chinyezi. Ma flaker ogula pambuyo pake amalola kusungitsa pafupifupi 5,000 ppm ya chinyezi mu malonda ndikusunga nthawi zambiri madzi pamwamba. M'mayiko ena, kudyetsa chinyezi kumatha kufika pa 14,000 ppm ngakhale mutakhala m'thumba lalikulu.

Mulingo wonse wa madzi ndi kusiyanasiyana kwake, zomwe sizingatheke, ndizovuta kwambiri, ndizovuta kwambiri kwa screptter screwr ndi lingaliro logwirizana. Izi nthawi zambiri zimabweretsa kusinthasintha kwa kusintha kwa expreser.

2) Pet ndi hergroscopic ndipo imamwa chinyezi kuchokera mumlengalenga. Kuchuluka kwa chinyezi cha Hydrolyz. Pet iyenera kuwuma musanayambe kukonza, ndipo chiweto cha amorphous chimafunikira lisanakwane kuti tinthu tating'onoting'ono tisakumane kuti tisakhale limodzi pamene akusintha pamene akusintha.

Hydrolysis imatha kuchitika chifukwa cha chinyezi ndipo nthawi zambiri zimatha kuwoneka ngati kuchepa kwa iv (mawonekedwe a chidwi) a malonda. Pet ndi "Semi-Crystalline". IV ikachepetsedwa, mabotolowa amakhala opanda phokoso ndipo amakonda kulephera pa "chipata" (gawo la jekeseni) pakuwomba ndi kudzaza.

M'dziko la "Crystaline" limakhala ndi ma crystalline ndi zigawo zamomwe zimayambitsa mawonekedwe ake. Gawoli la Crystalline limayamba pomwe mamolekyulu amadzigwirizanitsa mu mzere wokhazikika kwambiri. M'madera omwe si crystalline mamolekyulu amakhala munthawi yayitali. Poutukula kuti ma cystall anu ali okwera, asanakonzedwe, zotsatira zake zimakhala yunifolomu yochulukirapo.

Ode adapanga ziboda zovunda zozungulira zachita ntchito zomwe zimachitika munjira yayikulu kwambiri. Zopangidwa mwapadera radiation yofinya zimathandizira kusintha kwa kutentha kwa kutentha kwazinthu zowuma popanda kutenga gawo losakwanira pogwiritsa ntchito mpweya wabwino. Njira yotentha yotentha ndi nthawi yopuma imachepetsedwa kwa mphindi 8.5 pokhapokha ngati mphindi 20 kutengera ntchitoyo, maola angapo amawerengedwa kwa mpweya wabwino kapena mpweya wowuma.

Kuwuma kwa infrared kumatha kusintha magwiridwe antchito a Twin-screwder chifukwa kumachepetsa kuchepa kwa ma IV ndikuwongolera kwambiri kukhazikika kwa ntchito yonseyo.
