Asidi ya Methacrylic (asidi ya 2-Methyl-2-propenoic)
| Makhalidwe a mankhwala | Asidi ya Methacrylic, yomwe ndi chidule cha MAA, ndi chinthu chachilengedwe. Madzi okhuthala amenewa opanda mtundu ndi asidi wa carboxylic wokhala ndi fungo loipa. Amasungunuka m'madzi ofunda ndipo amatha kusakanikirana ndi zinthu zambiri zachilengedwe. Asidi ya Methacrylic imapangidwa m'mafakitale ambiri ngati choyambira cha ma esters ake, makamaka methyl methacrylate (MMA) ndi poly(methyl methacrylate) (PMMA). Ma methacrylates amagwiritsidwa ntchito kwambiri, makamaka popanga ma polima okhala ndi mayina amalonda monga Lucite ndi Plexiglas. MAA imapezeka mwachilengedwe pang'ono mu mafuta a chamomile ya ku Roma. | |
| Mapulogalamu | Methacrylic acid imagwiritsidwa ntchito popanga ma resins ndi mapulasitiki a methacrylate. Imagwiritsidwa ntchito ngati Monomer ya ma resins ndi ma polima akuluakulu, kupanga zinthu zachilengedwe. Ma polima ambiri amachokera ku ma esters a asidi, monga methyl, butyl, kapena isobutyl esters. Methacrylic acid ndi methacrylate esters amagwiritsidwa ntchito kukonzekera ma polima osiyanasiyana [→ Polyacrylamides ndi Poly(Acrylic Acids), → Polymethacrylates]. Poly(methyl methacrylate) ndiye polima wamkulu m'gululi, ndipo amapereka mapulasitiki olimba komanso oyera ngati madzi omwe amagwiritsidwa ntchito ngati pepala mu glazing, signs, displays, ndi ma lighting panels. | |

Chitetezo
Mukamagwiritsa ntchito mankhwalawa, chonde tsatirani malangizo ndi chidziwitso chomwe chaperekedwa mu pepala la deta yachitetezo ndipo tsatirani njira zodzitetezera komanso zaukhondo kuntchito zoyenera pogwiritsira ntchito mankhwala.
Zindikirani
Deta yomwe ili m'buku lino imachokera ku chidziwitso chathu chamakono komanso zomwe takumana nazo. Poganizira zinthu zambiri zomwe zingakhudze kukonza ndi kugwiritsa ntchito malonda athu, deta iyi siimasula opanga kuti achite kafukufuku wawo ndi kuyesa; deta iyi sikutanthauza chitsimikizo chilichonse cha katundu wina, kapena kuyenerera kwa malondawo pacholinga china. Mafotokozedwe aliwonse, zojambula, zithunzi, deta, kuchuluka, kulemera, ndi zina zotero zomwe zaperekedwa pano zitha kusintha popanda chidziwitso cham'mbuyomu ndipo sizipanga mtundu wa malonda womwe wavomerezedwa. Ubwino wa malonda womwe wavomerezedwa umachokera kokha ku mawu omwe aperekedwa mu ndondomeko ya malonda. Ndi udindo wa wolandira malonda athu kuonetsetsa kuti ufulu uliwonse wa mwiniwake ndi malamulo ndi malamulo omwe alipo akutsatiridwa.
