Intshayelelo
Kwii-methyl methacrylateInkqubo yemveliso, ukujonga ngokuchanekileyo ubumsulwa be-monomer kunye nokusebenza kwayo kubalulekile ukuze kubekho i-polymerization eqhubekayo. Iindlela ze-bulk polymerization kwimveliso ye-acrylic zifuna ulawulo oluqinileyo lwe-radical initiator dosing kunye nokususwa kobushushu.
Iinkqubo zokwenziwa kwe-acrylic sheet polymerization zixhomekeke kufundo lwexesha langempela lokulinganisa, ukuxuba, kunye nokufaka umbane ukuthintela iziphene kunye nezixhobo ezingaqhelekanga. Ulawulo oluchanekileyo loxinano luvelisa ukucaca okuphezulu kunye nokufana kwimveliso ye-acrylic sheet.
Isishwankathelo seNkqubo yoShishino oluPhambili
Inkqubo yokuvelisa i-methyl methacrylate isebenzisa i-catalytic methylation okanye i-oxidative esterification ngqo ukwenza i-MMA monomer. I-Catalytic methylation idla ngokusebenzisa i-mixed Mg/Ga oxide catalysts, ifezekisa ukukhetha okuphezulu kunye nesivuno, ngelixa inciphisa ukwakheka kwemveliso ephumayo. I-Direct methylation, eyenziwe kwi-Aspen Plus, ivumela ukuphinda isetyenziswe ngokufanelekileyo, ivumela ubumsulwa be-MMA ukuya kuthi ga kwi-99.9% ngokusetyenziswa kwamandla okuncitshisiweyo.
Umzobo wokuhamba kwenkqubo ye-methyl methacrylate ugubungela ukufakwa kwezinto eziluhlaza, amanyathelo okucoca i-MMA, kunye namanqanaba okuzinzisa. I-MMA ezinzileyo emva koko ihanjiswa kwiiyunithi ze-bulk polymerization ngemibhobho evaliweyo, ukunciphisa ungcoliseko kunye nokulahleka.
Inkqubo ye-methyl methacrylate bulk polymerization ibandakanya abaqalisi be-radical, ulawulo lobushushu oluchanekileyo, kunye nokusasazwa kwe-polymer chain okuqhubekayo. Ulawulo lobushushu lwe-reactor luqinisekisa ukuguqulwa okufanayo kwaye luthintela iimpendulo ze-exothermic ezibalekayo.
Ulawulo lwenkqubo yokwenziwa kwamaphepha e-acrylic luxhomekeke kwidosi echanekileyo, ukuxubana okucoliweyo kakhulu, kunye nokuphoswa okulinganisiweyo. Iindlela zokucubungula amaphepha e-acrylic ezifana nokupholisa okulawulwayo kunye nolawulo lwamaqamza zibalulekile ukuze kucace kakuhle kwaye kufane. Inyathelo ngalinye lifuna ukubekwa esweni okuqinileyo komgangatho wemveliso ozinzileyo.

Uxinano lwexesha langempela Imingeni yokulinganisa inAi-crylicSiheetMukwenziwa kwezinto ezintsha
Umlinganiselo woxinano oluphakathi kunye noxinzelelo kwinkqubo yokwenziwa kwephepha le-acrylic ijongene nemingeni eqhubekayo evela kwi-process dynamics kunye nokuguquguquka kwezinto. Amaqondo obushushu aphezulu kwiindawo ezisabelayo ze-exothermic akhawulezisa ukungcoliswa kwe-sensor, okubangela ukulahleka kokushukuma kunye nokulinganiswa. Inkqubo ye-methyl methacrylate bulk polymerization ibonakalisa ukuguquguquka okukhawulezileyo kwe-viscosity, okuphazamisa ukuzinza kwemitha yoxinano kwaye ifuna ukuhlaziywa rhoqo.
Iinxalenye ze-resin ezixhonyiweyo kunye nokwahlukana kwesigaba ngexesha lenkqubo ye-acrylic sheet polymerization kunciphisa ngokuthe ngqo ukuchaneka kwe-inline sensor, njengoko impendulo yesixhobo inengxaki yokusasazeka kunye nokuhamba okungalinganiyo. Iindawo ezingaphakathi kwenkqubo zinokuba nomxholo we-bubble oguquguqukayo okanye ukwakheka kwe-microgel, ukujika uxinano kunye nedatha yoxinzelelo ngenxa yokungafani okwethutyana.
