I-Methacrylic acid (i-2-Methyl-2-propenoic acid)
| Izinhlobo zamakhemikhali | I-Methacrylic acid, efushanisiwe nge-MAA, iyinhlanganisela yezinto eziphilayo. Lolu ketshezi olungenambala, oluqinile luyi-carboxylic acid enephunga elibi elibi. Luyancibilika emanzini afudumele futhi luxubene nezinyibilikisi eziningi zezinto eziphilayo. I-Methacrylic acid ikhiqizwa ezimbonini ngezinga elikhulu njengesandulela sama-ester ayo, ikakhulukazi i-methyl methacrylate (MMA) kanye ne-poly(methyl methacrylate) (PMMA). Ama-methacrylates anezindlela eziningi zokusetshenziswa, ikakhulukazi ekwakhiweni kwama-polymer anamagama okuhweba njenge-Lucite ne-Plexiglas. I-MAA ivela ngokwemvelo ngamanani amancane emafutheni e-chamomile yamaRoma. | |
| Izicelo | I-Methacrylic acid isetshenziswa ekwenziweni kwama-resin namapulasitiki e-methacrylate. Isetshenziswa njenge-Monomer yama-resin nama-polymer amakhulu, ukwenziwa kwezinto eziphilayo. Ama-polymer amaningi asekelwe kuma-esters e-asidi, njenge-methyl, i-butyl, noma ama-isobutyl esters. Ama-ester e-Methacrylic acid nama-methacrylate asetshenziselwa ukulungiselela uhla olubanzi lwama-polymer [→ Ama-Polyacrylamides nama-Poly(Acrylic Acids), → Ama-Polymethacrylates]. I-Poly(methyl methacrylate) iyi-polymer eyinhloko kulesi sigaba, futhi inikeza amapulasitiki aqinile nahlanzekile amanzi asetshenziswa ngesimo seshidi ekugcazeni, ezimpawini, ezibonisini, nasezibanini. | |

Ukuphepha
Uma uphatha lo mkhiqizo, sicela ulandele iseluleko nolwazi olunikezwe ephepheni ledatha yokuphepha futhi ulandele izinyathelo zokuvikela nezokuhlanzeka endaweni yokusebenza ezifanele zokuphatha amakhemikhali.
Inothi
Idatha equkethwe kulolu shicilelo isekelwe olwazini lwethu lwamanje kanye nokuhlangenwe nakho. Ngenxa yezici eziningi ezingase zithinte ukucutshungulwa nokusetshenziswa komkhiqizo wethu, le datha ayibakhululi abaprosesa ekwenzeni uphenyo lwabo kanye nokuhlolwa; futhi le datha ayisho noma yisiphi isiqinisekiso sezakhiwo ezithile, noma ukufaneleka komkhiqizo ngenhloso ethile. Noma yiziphi izincazelo, imidwebo, izithombe, idatha, izilinganiso, izinsimbi, njll. ezinikezwe lapha zingashintsha ngaphandle kolwazi lwangaphambilini futhi azihlanganisi ikhwalithi yesivumelwano esivunyelwene ngayo yomkhiqizo. Ikhwalithi yesivumelwano esivunyelwene ngayo yomkhiqizo iphumela kuphela ezitatimendeni ezenziwe ekucacisweni komkhiqizo. Kungumthwalo wemfanelo womamukeli womkhiqizo wethu ukuqinisekisa ukuthi noma yimaphi amalungelo obunikazi kanye nemithetho ekhona kanye nemithetho kuyagcinwa.
