Kuchinja-chinja kwehuwandu hwemonomer-to-polymer panguva yekugadzira methyl methacrylate kunokanganisa zvakananga kudzora huremu hwemamorekuru, kujeka kwemaziso, uye mashandiro emakanika. Mhinduro yekukurumidza yemaitiro inobvumira dosing chaiyo munhanho yega yega yekugadzira methyl methacrylate, zvichideredza kukundikana kwebatch kunodhura. Kuyerwa kuri mukati memutsetse mudhiyagiramu yekuyerera kwemaitiro emethyl methacrylate kunoita kuti vashandisi vaonekwe nguva dzose, zvichitsigira stable radical polymerization, kunyanya panguva yekuchinja kwakanyanya kwe exotherm uye viscosity.
Kutarisa nemazvo kunoderedza marara ezvishandiso ne10%–12%, zvichienderana nemiedzo yakaitwa munguva pfupi yapfuura muindasitiri, zvichitsigira zvakananga kugadzirwa kwegoho. Ruzivo rwehuwandu hwezvishandiso panguva chaiyo runowedzera kushanda zvakanaka kwezvishandiso uye runobatsira kudzivirira nguva dzisina kurongwa dzakabatana nekutsauka kusingaonekwe kana kukundikana kwepolymerization.

Mumethyl methacrylateMaitiro ekugadzira, kutarisa kwakanyatsojeka kwekuchena kwemonomer uye reactivity zvakakosha kuti pave nepolymerization inogara iripo. Nzira dzepolymerization yakawanda mukugadzira acrylic dzinoda kudzora kwakasimba kwe radical initiator dosing uye kubvisa kupisa.
Maitiro ekugadzira purasitiki yeacrylic sheet anoshandisa kuverenga panguva chaiyo kwekuyerwa, kusanganiswa, uye kuumbwa kwesimbi kudzivirira zvikanganiso nezvinhu zvisina kutsanangurwa. Kudzora density kwakarurama kunoita kuti pave nekujeka kwakanyanya uye kufanana mukugadzirwa kwepurasitiki yeacrylic.
Pfupiso Yemaitiro Akakosha Eindasitiri
Maitiro ekugadzira methyl methacrylate anoshandisa catalytic methylation kana direct oxidative esterification kugadzira MMA monomer. Catalytic methylation inowanzo shandisa mixed Mg/Ga oxide catalysts, ichiwana sarudzo yepamusoro uye goho, uku ichideredza kugadzirwa kwezvigadzirwa. Direct methylation, yakagadzirwa muAspen Plus, inobvumira kudzokorodza kunoshanda, ichibvumira MMA kuchena kusvika ku99.9% kana kushandiswa kwesimba kwakaderera.
Dhayagiramu yekuyerera kwemaitiro emethyl methacrylate inosanganisira zvinopinda muzvinhu zvakabikwa, matanho ekuchenesa MMA, uye matanho ekusimbisa. MMA yakagadzikana inozoendeswa kumayuniti epolymerization akawanda kuburikidza nemapombi akavharwa, zvichideredza kusvibiswa uye kurasikirwa.
Maitiro e methyl methacrylate bulk polymerization anosanganisira ma radical initiators, kutonga kupisa kwakanyatsojeka, uye kupararira kwe polymer chain nguva dzose. Kudzora kupisa kwe reactor kunoita kuti pave nekushanduka kwakafanana uye kudzivirira runaway exothermic reactions.
Kudzora maitiro ekugadzira machira eacrylic kunoenderana nekuyera kwacho, kusanganisa machira akawanda, uye kukanda zvinhu zvakakamurwa. Matekiniki ekugadzirisa machira eacrylic akadai sekutonhodza kwakadzorwa uye kutonga mabubble akakosha kuti zvive pachena uye zvakafanana. Danho rega rega rinoda kutariswa kwakasimba kuti chigadzirwa chive chakasimba.

Kuwanda kwenguva chaiyo Matambudziko ekuyera inAcrylicSheetMkugadzira zvinhu
Kuyerwa kwehuwandu hwemukati uye huwandu hwezvinhu mukugadzirwa kwe acrylic sheet kunosangana nematambudziko anogara achiitika kubva mukusiyana kwemaitiro uye kusiyana kwezvinhu. Kupisa kwakanyanya munzvimbo dzinopisa dzinoita kuti sensor iite tsvina, zvichikonzera kurasikirwa nekudonha uye kuyera. Maitiro e methyl methacrylate bulk polymerization anokurumidza kuchinja-chinja viscosity, zvichikanganisa kugadzikana kwe density meter uye zvinoda kugadziriswazve nguva nenguva.
Zvidimbu zve resin zvakasungirirwa uye kupatsanurwa kwechikamu panguva ye acrylic sheet polymerization zvinoderedza zvakananga kururamisa kwe inline sensor, sezvo mhinduro yemidziyo ichitambura nekupararira uye kuyerera kusina kuenzana. Nzvimbo dziri mukati meiyi nzira dzinogona kunge dziine huwandu hwebubble hunochinja kana kugadzirwa kwe microgel, kukanganisa density uye data re concentration nekuda kwe transient heterogeneity.
Mamita emukati anofanirwa kuunganidza zviyero zvakarurama uye kutsungirira kutenderera kwakazara kwedhiragiramu yekuyerera kwemethyl methacrylate, kusanganisira kucheneswa kweMMA, kugadzikana, uye nzira yepolymerization yakawanda mukugadzirwa kweacrylic. Zvinhu zve sensor zvepamusoro uye magadzirirwo anodiwa kuderedza nguva yekushanda uye kuwedzera kurongeka kwekuyera munhanho yega yega yekugadzira acrylic sheet.

Kuwanda kweLonnmeter inline uyemita dzekuyerainopa zviyero zvakananga, zvisingapindike mukati mechikamu chimwe nechimwe chekugadzirwa kwepepa re acrylic, kusanganisira maitiro e methyl methacrylate bulk polymerization. Nguva dzekupindura kwemasensa dziri pasi pemasekondi 0.5 dzinogonesa kudzora maitiro zvakananga, zvichitsigira dosing chaiyo uye casting panguva yekugadzirwa kwepepa re acrylic.
Dhizaini yemidziyo yakasimba inodzivirira kudonha kwemasensa kunokonzerwa nekupisa kwakanyanya, zvidimbu zve resin zvakasungirirwa, huwandu hwemabubble anochinja-chinja, uye kugadzirwa kwe microgel. Midziyo yeLonnmeter inochengetedza ±0.003kurongeka kwe g/cm³ kuburikidza nenzvimbo dzekupisa dzinochinja-chinja uye zvikamu zvakasiyana-siyana.
Deredza mabheti asina kutsanangurwa uye marara ezviwanikwa. Taura zvishandiso zvekubatanidza zvakananga mudhiyagiramu yekuyerera kwemaitiro emethyl methacrylate uye nzira yepolymerization yakawanda mukugadzirwa kweacrylic. Bata mainjiniya wekutengesa weLonnmeter izvozvi.
