Njengengxenye ebalulekile embonini yamakhemikhali,i-methyl methacrylate (ngemuva kwalokhu ebizwa ngokuthi "i-MMA")idlala indima ebalulekile emikhakheni efana ne-polymer synthesis, izinto ezibonakalayo, kanye ne-HEMA (izinto ze-thermoplastic polyester). Ukukhetha umphakeli we-MMA onokwethenjelwa akuhlobene nje kuphela nokusebenza kahle kokukhiqiza kodwa futhi kuthinta ngokuqondile ikhwalithi yomkhiqizo nemiphumela yohlelo lokusebenza. Lesi sihloko sizohlinzeka ngomhlahlandlela ophelele wabahlinzeki bamabhizinisi amakhemikhali kusukela ezicini zokuhlanzeka kanye nokucaciswa kwesicelo.
Izakhiwo Eziyisisekelo Nezinkambu Zokusebenza ze-MMA
I-Methyl methacrylate iwuketshezi olungenambala futhi olusobala olunesisindo esincane sengqamuzana nendawo yokubilisa emaphakathi, okwenza kube lula ukuyicubungula. Isebenza kahle kakhulu ekuphenduleni kwe-polymerization futhi isetshenziswa kabanzi ekwenzeni izinto ezihlukahlukene ze-polymeric, njengezingubo zokugqoka, amapulasitiki, nezinto ezibonakalayo. Ukusebenza okuhle kakhulu kwe-MMA kuyenza ibe yinto ebalulekile embonini yesimanje.
Umthelela Wobumsulwa ekusebenzeni kwe-MMA
Ukuhlanzeka kwe-MMA kuthinta ngqo ukusebenza kwayo ezinhlelweni ezahlukene. Ukuphakama kokuhlanzeka, kungcono ukusebenza kwezinto ezibonakalayo mayelana nokumelana nesimo sezulu kanye nokumelana nomthelela. Ekuphenduleni kwe-polymerization, ubumsulwa obuphansi be-MMA bungase bethule ukungcola, buthinte umsebenzi wokusabela kanye nekhwalithi yomkhiqizo. Uma ukhetha umhlinzeki, kuyadingeka ukuthi udinge ukuthi okuqukethwe kokungcola kwe-MMA kuphansi kunezindinganiso zomkhakha ukuze kuqinisekiswe ukuvumelana nokuthembeka komkhiqizo.
Amazinga Wokutholwa Ahlobene Nokuhlanzeka
Ukutholwa kokuhlanzeka kwe-MMA kuvame ukuqedelwa ubuchwepheshe bokuhlaziya obuthuthukile obufana ne-GC-MS (i-gas chromatography-mass spectrometry). Abahlinzeki kufanele banikeze imibiko yokuhlola enemininingwane ukuze baqinisekise ukuthi i-MMA ihlangabezana namazinga ekhwalithi. Ukutholwa kobumsulwa akunciki kuphela kumathuluzi kodwa futhi kudinga ukuhlanganisa ulwazi lwamakhemikhali ukuze kuqondwe imithombo nemithelela yokungcola.
Isitoreji Nokucaciswa Kokusetshenziswa kwe-MMA
Indawo yokugcina i-MMA inezidingo eziphezulu futhi idinga ukugcinwa endaweni eyomile, engenamoya, nepholile. Gwema ukukhanya kwelanga okuqondile ukuze uvimbele ukukhululwa kwezinto eziyingozi ngenxa yokubola. Uma isetshenziswa, kufanele kuqashelwe ukuzinza kwe-MMA ukuze kugwenywe ukulimala komkhiqizo okubangelwa izinga lokushisa eliphezulu noma ukudlidliza okuqinile. Ukucaciswa kokugcinwa nokusetshenziswa yizici ezibalulekile zokuqinisekisa ukusebenza kwe-MMA.
Iziphakamiso zokukhetha abahlinzeki be-MMA
1.Isitifiketi sekhwalithi: Abahlinzeki kufanele baphathe isitifiketi se-ISO ukuze baqinisekise ukuthi ikhwalithi yomkhiqizo ihlangabezana nezindinganiso zamazwe ngamazwe.
2.Imibiko yokuhlola: Idinga abahlinzeki ukuthi banikeze imibiko enemininingwane yokuhlola ukuhlanzeka ukuze kuqinisekiswe ukuthi ikhwalithi ye-MMA ihlangabezana namazinga.
3.Ukulethwa ngesikhathi: Ngokwezidingo zebhizinisi, abahlinzeki kufanele balethe imikhiqizo ngesikhathi ukugwema ukubambezeleka kokukhiqiza.
Isevisi ye-4.Ngemva kokuthengisa: Abahlinzeki abathembekile kufanele banikeze ukwesekwa kwezobuchwepheshe besikhathi eside namasevisi ukuze baqinisekise ukuthi izinkinga okuhlangatshezwane nazo ngesikhathi sokusetshenziswa zingaxazululwa ngesikhathi.
imibuzo ejwayelekile ukubuzwa
1.Kuthiwani uma ukuhlanzeka kunganele: Kungaxazululwa ngokushintsha umphakeli noma ngokudinga umbiko wokuhlola ukuhlanzeka okuphezulu.
2.Kuthiwani uma izimo zokugcina zingekho ezingeni: Kuyadingeka ukulungisa indawo yokugcina ukuze uqinisekise ukuthi izinga lokushisa kanye nomswakama kuhlangabezana nezindinganiso.
I-3.Indlela yokugwema ukungcoliswa kokungcola: Ungakhetha izinto zokusetshenziswa ngokuhlanzeka okuphezulu noma uthathe izinyathelo ezinjengokuhlunga ngesikhathi sokugcina.
Isiphetho
Njengempahla yamakhemikhali ebalulekile, ukuhlanzeka nokucaciswa kokusetshenziswa kwe-MMA kuthinta ngqo ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza. Ukukhetha umphakeli onokwethenjelwa akukwazi nje kuphela ukuqinisekisa ikhwalithi ye-MMA kodwa futhi kunikeze ukusekelwa okuthembekile kobuchwepheshe ekukhiqizeni okulandelayo nokusetshenziswa. Ngomhlahlandlela ongenhla, amabhizinisi amakhemikhali angakhetha abahlinzeki be-MMA ngokwesayensi ukuze kuqinisekiswe ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza.
