I-Methyl methacrylate (i-Methyl ester ye-2-methyl-2-propenoic acid)
| Ikhemikhaliniindawo | I-Methyl 2-methyl-2-propenoate inevumba elibi nelingena ngaphakathi. Kwenye ingxelo, le khompawundi ixelwe ukuba inevumba elibukhali nelifana neziqhamo.,I-Methyl methacrylate yikhompawundi yendalo enefomula i-CH2=C(CH3)COOCH3Olu lwelo lungenambala, i-methyl ester ye-methacrylic acid (MAA) yi-monomer eveliswa ngomlinganiselo omkhulu wokuvelisa i-poly(methyl methacrylate) (PMMA). | |
| Izicelo | I-Methyl methacrylatec isetyenziswa kwi-acrylic bone cement ezisetyenziswa kutyando lwamathambo; ekuveliseni ii-acrylic polymers, i-polymethylmethacrylate kunye nee-copolymers ezisetyenziswa kwi-acrylic surface coatings; ekwenzeni ii-emulsion polymers; ekuguquleni ii-polyester resins ezingagcwaliyo; ekuveliseni i-methacrylate ephezulu, ii-acrylic fibers, ifilimu ye-acrylic, ii-inks, i-radiation-polymerized impregnants zomthi, kunye ne-solvent-based adhesives kunye ne-binders; njenge-impact modifier ye-PVC; kwi-medical spray adhesives; kwi-non-irritant bandage solvents; kwi-dental technology njenge-ceramic filler okanye isamente; ukugquma ii-cornea contact lenses; kwi-intraocular lens, kwi-artificial nails, nakwi-hearing aid; njenge-monomer ye-polymethaerylate resins; ekufakweni kwe-concret. | |
| Okoqobofi-orm | Ulwelo olucacileyo, olungenambala, olunevumba elihlabayo nelinjengeziqhamo | |

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.
