Asiidh Methacrylic ah (2-Methyl-2-propenoic acid)
| Dabeecadaha kiimikada | Asiidhka Methacrylic, oo loo soo gaabiyo MAA, waa isku-dhis dabiici ah. Dareeren aan midab lahayn oo viscous ah waa asiidh carboxylic ah oo leh ur aan fiicnayn. Waxaa lagu milmaa biyaha diirran waxaana lagu milan karaa inta badan dareerayaasha dabiiciga ah. Asiidhka Methacrylic waxaa lagu soo saaraa warshad ahaan si ballaaran iyadoo ah horudhac u ah esters-keeda, gaar ahaan methyl methacrylate (MMA) iyo poly (methyl methacrylate) (PMMA). Methacrylates-ku waxay leeyihiin isticmaallo badan, gaar ahaan soo saarista polymers leh magacyo ganacsi sida Lucite iyo Plexiglas. MAA si dabiici ah ayay ugu dhacdaa xaddi yar saliidda chamomile-ka Roomaanka. | |
| Codsiyada | Asiidhka Methacrylic waxaa loo isticmaalaa soo saarista resins-ka methacrylate iyo balaastikada. Waxaa loo isticmaalaa Monomer-ka resins-ka mugga weyn iyo polymers-ka, isku-darka dabiiciga ah. Polymers-ka badankoodu waxay ku salaysan yihiin esters-ka aashitada, sida methyl, butyl, ama isobutyl esters. Asiidhka Methacrylic iyo esters-ka methacrylate waxaa loo isticmaalaa in lagu diyaariyo noocyo badan oo polymers ah [→ Polyacrylamides iyo Poly(Acrylic Acids), → Polymethacrylates]. Poly(methyl methacrylate) waa polymer-ka ugu weyn ee qaybtan, wuxuuna bixiyaa balaastikada adag ee biyaha cad oo loo isticmaalo qaab xaashi ah oo ku jira muraayadaha, calaamadaha, bandhigyada, iyo muraayadaha iftiinka. | |

Badbaadada
Markaad la macaamilayso badeecadan, fadlan raac talada iyo macluumaadka ku qoran xaashida xogta badbaadada oo raac tallaabooyinka ilaalinta iyo nadaafadda goobta shaqada ee ku filan maaraynta kiimikooyinka.
Fiiro gaar ah
Xogta ku jirta daabacaadan waxay ku salaysan tahay aqoontayada iyo waayo-aragnimadayada hadda jirta. Marka la eego arrimo badan oo saameyn kara habaynta iyo adeegsiga badeecadeenna, xogtani kama yareyso farsameeyayaasha inay sameeyaan baaritaannadooda iyo baaritaannadooda; xogtanina macnaheedu maaha wax dammaanad ah oo ku saabsan sifooyin gaar ah, ama ku habboonaanta badeecadda ujeedo gaar ah. Sharraxaad kasta, sawirro, sawirro, xog, cabbir, miisaan, iwm. oo halkan lagu bixiyay way isbeddeli kartaa iyada oo aan la helin macluumaad hore mana aha tayada qandaraaska ee la isku raacay ee badeecada. Tayada qandaraaska ee la isku raacay ee badeecaddu waxay ka timaaddaa oo keliya hadallada lagu sameeyay qeexitaanka badeecada. Waa mas'uuliyadda qaataha badeecadeenna inuu hubiyo in xuquuq kasta oo gaar ah iyo sharciyo iyo sharciyo jira la ilaaliyo.
