Methyl methacrylate (Methyl ester oo ka samaysan 2-methyl-2-propenoic acid)
| Kiimikonatures | Methyl 2-methyl-2-propenoate wuxuu leeyahay ur qalalan oo qoto dheer. Warbixin kale ayaa lagu sheegay in isku-darkani uu leeyahay ur fiiqan oo miro leh.,Methyl methacrylate waa iskudhis dabiici ah oo leh qaacidada CH2=C(CH)3)COOCH3Dareere aan midab lahayn, methyl ester-ka methacrylic acid (MAA) waa monomer lagu soo saaro heer ballaaran oo loogu talagalay soo saarista poly (methyl methacrylate) (PMMA). | |
| Codsiyada | Methyl methacrylatec waxaa loo isticmaalaa sibidhka lafaha acrylic ee loo isticmaalo qalliinka lafaha; soo saarista polymers-ka acrylic, polymethylmethacrylate iyo copolymers-ka loo isticmaalo dahaarka dusha sare ee acrylic; soo saarista polymers-ka emulsion-ka; wax ka beddelka resins-ka polyester-ka aan buuxin; soo saarista methacrylate sare, fiilooyinka acrylic, filimka acrylic, khad, waxyaabaha lagu dhejiyo shucaaca ee loo yaqaan polymerized ee alwaaxa, iyo dhejisyada iyo isku xidhka dareeraha ku salaysan; sida wax ka beddelka saameynta ee PVC; dhejisyada buufinta daawada; dareerayaasha faashadda aan cuncunka lahayn; tignoolajiyada ilkaha sida buuxinta dhoobada ama sibidhka; si loogu dahaadho muraayadaha indhaha; muraayadaha indhaha, ciddiyaha macmalka ah, iyo qalabka maqalka; sida monomer resins-ka polymethaerylate; ku dahaadhida konkritka. | |

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.
