Njira Zopangira ndi Kuyenda kwa HPMC

Kutsegulidwa kwa thonje-kuloza-kuloza-kulongeza-kuthyolako - thonje loyenga limatsegulidwa kuti uchoke chitsulo kenako nkuphwanyidwa. Wokongoletsa wokonzayo ali mu mawonekedwe a ufa, wokhala ndi tinthu tating'onoting'ono ta 80 ndi kupatsirana kwa 100%. Kupanda kutero, ndizosavuta kuyamwa limodzi panthawi yomwe mwachita ndikuchepetsa luso.

Alkirization: Onjezani thonje loyenerera pambuyo pa thonje kutsegulira thonje kwa chosungunulira, ndikuwayambitsa ndi madzi otsekemera a thonje lokonzanso mamolekyulu amtundu wa mafano. Alkali omwe amagwiritsidwa ntchito alkalization ndi mankhwala azitsulo kapena alkali. Kuchuluka kwa alkali kuwonjezeredwa (ndi misa, zomwezi pansipa) ndi 0.1-0.6 nthawi yotsekera, kuchuluka kwa madzi ofewa omwe amawonjezedwa ndi thonje. Kusungunulira kosakaniza ndi chisakanizo cha mowa ndi hydrocarborbor, ndi kuchuluka kwa ntchentche yowonjezera ndi 0.3-1.0 nthawi ya thonje loyenga. Nthawi za 7 -15 za izi: Chosungulumwa chimathanso kumwa ma atomu a kamota 3-5 (monga mowa, prosenol), acetone. Ikhozanso kukhala ma hydrocarbons ndi ma hydrocarbons onunkhira; Kutentha kuyenera kulamulidwa mkati mwa 0-5 ° C nthawi yokwanira; Nthawi ya ma alkishilization ndi pafupifupi 1hr. Kusintha kwa kutentha ndi nthawi zitha kutsimikiza malinga ndi zofunikira ndi zofunikira.

Kuyesa: Pambuyo pa mankhwala othandizira, pansi pa vacuum mikhalidwe, othandizira owonjezera amawonjezeredwa kuti ayesenso, ndipo wothandizila ndi ma propylene oxide. Kuti muchepetse kugwiritsa ntchito othandizira, panthawi yowunikira, kuchuluka kwa zowonjezera koyamba ndi thonje loyenerera, ndipo kuchuluka kwa zowonjezera ziwiri ndi 1.5--4 nthawi zomwe zimapangidwa ndi thonje loyenga. Nthawi. Pambuyo powonjezera Wothandizira koyamba, akuyambitsa ku ≤30 ° C kwa 45min-90min, ndiye kuti muchepetse ku Ethertherm ≤ oyambitsa, nthawi yachiwiri kuti ithe 30-120min, kenako nkutentha? ? ? Chitani Chikondwerero, nthawi ndi 1-4h, pa nthawi ino, thonje loyenerera limakhudzidwa kwathunthu ndi othandizira kuti athandizidwe ndi kupanga H-HPC.

Kuphwanya ndi kuphwanya: Kuphwanya ndi kuzolowera zouma zapano zomwe zapangidwazo mutatha kuphwanya ndi ma mesh ndi ma mesh ndi zofuna za ogwiritsa ntchito. Kenako pangani fakitale
