Kulamulira Kukhazikika kwa NaOH mu Kupanga Kwapakati Kwachilengedwe
Mu kapangidwe ka zinthu zamkati zosakanikirana ndi organic, kuwongolera molondola kuchuluka kwa sodium hydroxide (NaOH) ndikofunikira kwambiri pa khalidwe la zinthu, magwiridwe antchito, komanso phindu. Kugwiritsa ntchito NaOH popanga zinthu zamkati zosakanikirana ndi organic monga phenoxide salts ndi alkoxide salts kumachita gawo lofunikira kwambiri pakupanga utoto, mankhwala, ndi zinthu za polymeric, chifukwa zinthu zamkatizi zimakhala ngati zomangira zofunika kwambiri popanga zinthu zamkati zosakanikirana ndi organic.
Pakupanga phenoxide ndi mchere wa alkoxide, njira yogwirira ntchito ya NaOH imachokera ku alkalinity yake yamphamvu. Kudzera mu ukadaulo wa inline ultrasonic sensing, njira yopangira NaOH-mediated synthesis imatha kuyang'aniridwa nthawi yeniyeni pazigawo zosiyanasiyana.
Mavuto mu Kulamulira Kuchuluka kwa NaOH kwa Kupanga Kwapakati Kwachilengedwe
Kulamulira kuchuluka kwa NaOH mu kapangidwe ka organic intermediate kumabweretsa mavuto ofunikira okhudzana ndi makhalidwe ake a mankhwala ndi momwe zinthu zimayendera. Kuchepa kwake kwa kusungunuka mu zosungunulira zachilengedwe kumayambitsa mvula, pomwe kusasakanikirana bwino mu ma reactor akuluakulu kumabweretsa kusintha kwa kuchuluka kwa madzi—zomwe zimafooketsa mapangidwe a phenoxide/alkoxide ofanana.
Muli ndi mafunso okhudza kukonza njira zopangira？
Malo Okhazikitsira Mita Yochulukira Paintaneti mu Kulamulira Kuchuluka kwa NaOH
Mamita oyezera kuchuluka kwa anthu pa intaneti amayikidwa makamaka m'maulalo anayi ofunikira a njira, omwe amayang'ana kwambiri kuwunika kwa NaOH nthawi yeniyeni kuti atsimikizire kukhazikika kwa njira:
Kukonzekera kwa Zinthu Zopangira NaOH
Pokonzekera NaOH yolimba kukhala njira zochepetsera zomwe zimafunikira njira,kuchuluka kwa sodium hydroxidemitayaikidwa pakunjandi mixingthanki. Imasintha kuchuluka kwa zinthu zomwe zayesedwa kukhala kuchuluka kwa zinthu zomwe zasungidwa nthawi yeniyeni, kupewa zolakwika kuchokera pakukonza ndi manja ndikuwonetsetsa kuti kuchuluka kwa zinthu zomwe zasungidwa m'nthaka ndi kolondola.
Chithandizo cha Chakudya Choyambitsa Kuyankha
Yankho la NaOH lisanalowe mu reactor,chowunikira kuchuluka kwa sodium hydroxideimayikidwa pa payipi ya NaOH feed. Imatsimikizira kuti kuchuluka kwa madzi kukugwirizana ndi zomwe zili mkati mwake kuti ipewe kupangika kosakwanira kwapakati kapena zochitika zina zomwe zimachitika chifukwa cha kuchuluka kwa madzi komwe sikunatsimikizidwe.
Kuwunika Zomwe Zikuchitika Mu Njira
Pa zochitika zomwe kuchuluka kwa NaOH kumasintha mosinthasintha, choyezera kuchuluka kwa madzi chimayikidwa pa payipi yoyendera madzi ya mkati mwa reactor kapena payipi yoyezera madzi yotulukira. Chimatsata kusinthasintha kwa kuchuluka kwa madzi nthawi yeniyeni kuti chiwongolere kupanga kwa NaOH panthawi yake, kupewa hydrolysis kapena kuyankha kosakwanira.
Kuchira/Kusamba Pambuyo pa Chisoni
Ngati NaOH yosayatsidwa ibwezeretsedwanso kapena kugwiritsidwa ntchito potsuka zinthu, choyezera kuchuluka kwa madzi chimayikidwa pa malo osungiramo madzi obwezeretsa. Chimayang'anira kuchuluka kwa NaOH yobwezeretsedwanso, kudziwa ngati iyenera kuchepetsedwa kapena kuwonjezeredwa, ndikuwonetsetsa kuti kuchuluka kwa madzi otsukira kukukwaniritsa zofunikira za kuyera (monga, kupewa zotsalira zambiri za NaOH m'magawo apakati).
Dziwani Zambiri Zokhudza Ma Meter Ochulukirachulukira
Ubwino Womwe Umabwera Chifukwa cha Sodium Hydroxide Concentration Meter
Chiyeso cha kuchuluka kwa sodium hydroxide (NaOH) chimapereka phindu lalikulu pakupanga kwapakati kwachilengedwe pothana ndi mavuto akuluakulu owongolera kuchuluka, ndi maubwino ofunikira motere:
●InetZimathandizira kuyang'anira nthawi yeniyeni komanso molondola, m'malo mwa njira zochedwetsa, zopanda intaneti monga titration. Mwa kusintha kuchulukana kukhala kokhazikika nthawi yomweyo, zimaonetsetsa kuti NaOH imakhala mkati mwa magawo omwe akufuna, kupewa kuchepetsa mlingo kapena kupitirira muyeso.
●IneZimathandizira kukhazikika kwa njira ndi kusinthasintha kwa zinthu. Mwa kupewa kugwiritsa ntchito kwambiri NaOH ndikulola kubwezeretsanso molondola kwa NaOH yosakhudzidwa, zimachepetsa ndalama zogulira zinthu ndikuchepetsa mavuto okonza zinyalala.
●It imawonjezera chitetezo ndi kutsatira malamulo. Machenjezo a nthawi yeniyeni okhudza kuchuluka kwa zinthu molakwika amachepetsa zoopsa za dzimbiri la reactor kapena kuthawa kwa exothermic. Kuphatikiza apo, ntchito yake yolemba deta imakwaniritsa zofunikira zoyang'anira kutsata kwa mafakitale monga mankhwala, zomwe zimapangitsa kuti njira zowunikira zikhale zosavuta.
