I-asidi yeMethacrylic (i-asidi ye-2-Methyl-2-propenoic)
| Iikhemikhali | I-asidi ye-Methacrylic, efinyeziweyo nge-MAA, yi-organic compound. Olu lwelo lungenambala, oluxineneyo yi-asidi ye-carboxylic enevumba elibi elibi. Lunyibilika emanzini afudumeleyo kwaye luxutywa nezinye izinyibilikisi ezininzi ze-organic. I-asidi ye-Methacrylic iveliswa kwimizi-mveliso ngokubanzi njengesandulela see-esters zayo, ngakumbi i-methyl methacrylate (MMA) kunye ne-poly(methyl methacrylate) (PMMA). Ii-methacrylates zisetyenziswa ngeendlela ezininzi, ngakumbi ekwenziweni kwee-polymers ezinamagama orhwebo afana ne-Lucite kunye ne-Plexiglas. I-MAA ivela ngokwendalo ngamanani amancinci kwioyile ye-chamomile yamaRoma. | |
| Izicelo | I-asidi ye-methacrylic isetyenziswa ekwenziweni kwee-resin ze-methacrylate kunye neeplastiki. Isetyenziswa njengeMonomer kwii-resin ezinkulu kunye neepolymers, i-organic synthesis. Uninzi lweepolymers lusekelwe kwii-esters ze-asidi, njenge-methyl, i-butyl, okanye ii-isobutyl esters. I-asidi ye-methacrylic kunye nee-esters ze-methacrylate zisetyenziselwa ukulungiselela uluhlu olubanzi lweepolymers [→ IiPolyacrylamides kunye neePoly(Acrylic Acids), → IiPolymethacrylates]. I-Poly(methyl methacrylate) yeyona polymer iphambili kolu didi, kwaye ibonelela ngeplastiki eqinileyo necacileyo emanzini esetyenziswa kwifomu yeshiti kwi-glazing, kwiimpawu, kwimiboniso, nakwiipaneli zokukhanyisa. | |

ukhuseleko
Xa uphatha le mveliso, nceda ulandele iingcebiso nolwazi olunikiweyo kwiphepha ledatha yokhuseleko kwaye ulandele amanyathelo okhuseleko kunye nococeko kwindawo yokusebenza afanelekileyo okuphatha iikhemikhali.
Phawula
Idatha equlethwe kule ncwadi isekelwe kulwazi lwethu lwangoku namava. Ngenxa yezinto ezininzi ezinokuchaphazela ukucutshungulwa nokusetyenziswa kwemveliso yethu, le datha ayibakhululi abaprosesa ekwenzeni uphando lwabo kunye novavanyo; kwaye le datha ayithethi siqinisekiso seempawu ezithile, okanye ukufaneleka kwemveliso ngenjongo ethile. Naziphi na iinkcazo, imizobo, iifoto, idatha, ubungakanani, ubunzima, njl.njl. ezinikwe apha zinokutshintsha ngaphandle kolwazi lwangaphambili kwaye aziyiyo umgangatho wesivumelwano esivunyiweyo wemveliso. Umgangatho wesivumelwano esivunyiweyo wemveliso uvela kuphela kwiingxelo ezenziwe kwinkcazo yemveliso. Luxanduva lomntu ofumana imveliso yethu ukuqinisekisa ukuba nawaphi na amalungelo obunini kunye nemithetho ekhoyo kunye nomthetho ziyalandelwa.
