Kusinthasintha kwa ma monomer-to-polymer ratios panthawi yopanga methyl methacrylate kumakhudza mwachindunji kuwongolera kulemera kwa mamolekyulu, kuwonekera bwino kwa kuwala, ndi magwiridwe antchito a makina. Kuyankha mwachangu kwa njira kumalola kugawa molondola mu gawo lililonse la njira yopangira methyl methacrylate, kuchepetsa kulephera kokwera mtengo kwa batch. Kuyeza kosalekeza kwa inline mu chithunzi cha mayendedwe a methyl methacrylate kumapatsa ogwiritsa ntchito mawonekedwe owoneka nthawi zonse, kuthandizira polymerization yokhazikika, makamaka panthawi ya kusintha kwakukulu kwa exotherm ndi viscosity.
Kuwunika molondola kumachepetsa zinyalala za zinthu zopangira ndi 10%–12%, malinga ndi mayeso aposachedwa amakampani, zomwe zimathandiza mwachindunji kukonza bwino zokolola. Deta yeniyeni ya inline density imawonjezera kugwiritsa ntchito bwino zinthu ndipo imathandiza kupewa nthawi zosakonzekera zolumikizidwa ndi kupotoka kosawoneka kapena kulephera kwa polymerization.
Kupanga Mapepala a MMA Acrylic

Chiyambi
Mumethyl methacrylateNjira zopangira, kuyang'anira bwino kuyera kwa monomer ndi reactivity ndikofunikira kuti polymerization ikhale yokhazikika. Njira zopangira polymerization yochuluka pakupanga acrylic zimafuna kuwongolera mwamphamvu kuchuluka kwa radical initiator ndi kuchotsa kutentha.
Njira zopangira polymerization ya pepala la acrylic zimadalira kuwerengedwa kwa nthawi yeniyeni kuti zigwiritsidwe ntchito poyesa, kusakaniza, ndi kuponyera kuti zisawonongeke ndi zinthu zosafunikira. Kulamulira kolondola kwa kuchulukana kumapereka kumveka bwino komanso kufanana kwabwino popanga pepala la acrylic.
Chidule cha Njira Yaikulu Yamakampani
Njira yopangira methyl methacrylate imagwiritsa ntchito catalytic methylation kapena direct oxidative esterification kuti ipange MMA monomer. Catalytic methylation nthawi zambiri imagwiritsa ntchito mixed Mg/Ga oxide catalysts, zomwe zimapangitsa kuti pakhale kusankha kwakukulu komanso phindu, pomwe imachepetsa kupanga kwa byproduct. Direct methylation, yopangidwa mu Aspen Plus, imalola kubwezeretsanso bwino, zomwe zimapangitsa kuti MMA ikhale yoyera mpaka 99.9% ndikugwiritsa ntchito mphamvu zochepa.
Chithunzi cha kayendedwe ka njira ya methyl methacrylate chimakhudza kulowetsa kwa zinthu zopangira, njira zoyeretsera MMA, ndi magawo okhazikika. Kenako MMA yokhazikika imaperekedwa ku mayunitsi opangidwa ndi polymerization ambiri kudzera mu mapaipi otsekedwa, kuchepetsa kuipitsidwa ndi kutayika.
Njira yopangira polymerization ya methyl methacrylate imakhudza oyambitsa ma radical, kasamalidwe ka kutentha kolondola, komanso kufalikira kwa unyolo wa polymer mosalekeza. Kuwongolera kutentha kwa reactor kumaonetsetsa kuti kusinthaku kukuchitika mofanana ndipo kumaletsa kusintha kwa exothermic.
Kuwongolera njira zopangira mapepala a acrylic kumadalira mlingo woyenera, kusakaniza kwambiri, ndi kuyika zinthu mozama. Njira zopangira mapepala a acrylic monga kuziziritsa kolamulidwa ndi kasamalidwe ka thovu ndizofunikira kwambiri kuti zinthu zikhale zomveka bwino komanso zofanana. Gawo lililonse limafuna kuyang'aniridwa kolimba kuti zinthu zikhale bwino.

Kuchuluka kwa nthawi yeniyeni Mavuto Oyesera inAcrylicSchipewaMkupanga zinthu
Kuyeza kuchuluka kwa zinthu ndi kuchuluka kwa zinthu mu njira yopangira mapepala a acrylic kumakumana ndi mavuto opitilira chifukwa cha kusintha kwa njira ndi kusinthasintha kwa zinthu. Kutentha kwambiri m'malo otenthetsera omwe amakhudzidwa ndi kutentha kwa zinthu kumathandizira kuti sensor iwonongeke, zomwe zimapangitsa kuti madzi asunthike komanso kuti asamayende bwino. Njira yopangira polymerization ya methyl methacrylate imapangitsa kuti ma viscosity asinthe mofulumira, zomwe zimasokoneza kukhazikika kwa mita ya density komanso zimafuna kuti magetsi azisinthidwa pafupipafupi.
Tinthu ta resin tomwe timapachikidwa ndi kulekanitsidwa kwa gawo panthawi ya polymerization ya acrylic sheet kumachepetsa mwachindunji kulondola kwa sensa yamkati, chifukwa yankho la chipangizocho limavutika ndi kufalikira ndi kuyenda kosagwirizana. Magawo omwe ali mkati mwa njirayi akhoza kukhala ndi kuchuluka kwa thovu kapena mapangidwe a microgel, kusokoneza kuchuluka ndi deta yowunikira chifukwa cha kusiyana kwakanthawi.
Mamita ozungulira ayenera kusonkhanitsa miyeso yolondola molondola ndikupirira kuzungulira kwathunthu kwa chithunzi cha methyl methacrylate process flow diagram, kuphatikiza kuyeretsa kwa MMA, kukhazikika, ndi njira yopangira ma polymerization ambiri popanga acrylic. Zipangizo ndi mapangidwe apamwamba a sensor amafunikira kuti achepetse nthawi yogwira ntchito ndikuwonjezera kulondola kwa muyeso pagawo lililonse popanga mapepala a acrylic.
Ubwino wa Lonnmeter Inline DensityMamita
Kuchuluka kwa Lonnmeter mkati ndizoyezera kuchuluka kwa madzikupereka miyeso yolondola, yosawononga nthawi yonse ya gawo lililonse la njira yopangira mapepala a acrylic, kuphatikizapo njira ya methyl methacrylate bulk polymerization. Nthawi yoyankha kwa masensa pansi pa masekondi 0.5 imathandizira kuwongolera mwachindunji njira, kuthandizira mlingo wolondola ndi kuponya panthawi ya njira ya polymerization ya mapepala a acrylic.
Kapangidwe ka zida zolimba kamalimbana ndi kusuntha kwa masensa komwe kumachitika chifukwa cha kutentha kwambiri, tinthu ta utomoni tomwe timapachikidwa, kuchuluka kwa thovu losinthasintha, ndi mapangidwe a microgel. Zipangizo za Lonnmeter zimasunga ±0.003kulondola kwa g/cm³ kudzera m'malo otentha osinthasintha komanso magawo osiyanasiyana.
Chepetsani magulu osagwiritsidwa ntchito ndi zinthu zina komanso kuwononga zinthu. Tchulani zida zolumikizirana mwachindunji mu chithunzi cha methyl methacrylate process flow diagram ndi njira yopangira polymerization yambiri popanga acrylic. Lumikizanani ndi mainjiniya ogulitsa a Lonnmeter pompano.
