I-Methyl methacrylate (i-Methyl ester ye-2-methyl-2-propenoic acid)
| Amakhemikhalini-atures | I-Methyl 2-methyl-2-propenoate inephunga elibukhali nelingena ngaphakathi. Komunye umbiko kubikwa ukuthi le nhlanganisela inephunga elibukhali nelinjengezithelo,I-Methyl methacrylate iyinhlanganisela ephilayo enefomula i-CH2=C(CH)3)COOCH3Lolu ketshezi olungenambala, i-methyl ester ye-methacrylic acid (MAA) luyi-monomer ekhiqizwa ngezinga elikhulu ukuze kukhiqizwe i-poly(methyl methacrylate) (PMMA). | |
| Izicelo | I-Methyl methacrylatec isetshenziswa kuma-cement ethambo e-acrylic asetshenziswa ekuhlinzeni kwamathambo; ekukhiqizweni kwama-polymer e-acrylic, i-polymethylmethacrylate kanye nama-copolymer asetshenziswa ekumbozweni kobuso be-acrylic; ekwakhiweni kwama-polymer e-emulsion; ekuguqulweni kwama-resin e-polyester angagcwalisiwe; ekukhiqizweni kwe-methacrylate ephezulu, imicu ye-acrylic, ifilimu ye-acrylic, uyinki, ama-impregnants e-radiation-polymerized okhuni, kanye nama-adhesives nama-binder asekelwe ku-solvent; njenge-modifier yomthelela we-PVC; kuma-adhesives e-medical spray; kuma-solvents e-bandage angacasuli; kubuchwepheshe bamazinyo njenge-ceramic filler noma i-samente; ukumboza amalensi okuxhumana e-cornea; kumalensi angaphakathi kweso, izinzipho zokwenziwa, kanye nezinsiza zokuzwa; njenge-monomer yama-resin e-polymethaerylate; ekufakweni kwe-concret. | |
| Okwemvelofi-orm | Uketshezi olucacile, olungenambala olunephunga elihlabayo nelinjengezithelo | |

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.
