Izinkambu Zokusebenza

Izimo zohlelo lokusebenza ezibalulekile ze-LMA:

1. Imboni yePolymer Synthesis

• Ihlanganisa i-poly(lauryl methacrylate) kanye nama-copolymers epulasitiki, irabha nama-elastomers.

• I-diluent esebenzayo yama-polyester resins (UPR), inciphisa ukuntengantenga kanye nephunga.

• I-plasticizer yangaphakathi yokuthuthukisa ukuguquguquka kwe-polymer ngaphandle kokuphazamisa ukusebenza.

2. Imboni Yezingubo Neziyinki

• Ithuthukisa ukuguquguquka, ukumelana nesimo sezulu kanye nokunamathela kokhuni/okwepulasitiki.

• Isetshenziswa kuma-UV kanye nama-varnishes ayelaphekayo ukuze kuthuthukiswe ukusebenza kahle kokwelapha.

• Ithuthukisa uketshezi lukayinki, ukunamathela kanye nokumelana namanzi ukuze kuphrintwe okucacile.

3. Izinamathiselo & Sealants Industry

• Ithuthukisa ukuguquguquka namandla okunamathelana okunamathelayo elapheka e-UV.

• Ithuthukisa ukuqina nokuqina kokunamathela kwesakhiwo kanye ne-anaerobic.

• Ithuthukisa ukuguquguquka nokunamathela kokunamathelayo okuzwela ukucindezela.

4. Daily Chemical & Related Industries

• Impahla eluhlaza ye-cosmetic (ihambisana nezindinganiso zokuphepha) yokuthungwa nokuzinza.

• Ihlanganiswe ibe izithasiselo zokuthambisa ukuze kuthuthukiswe ukusebenza kokugcoba.

5. Ezinye Izimboni

• I-ejenti yokuqeda isikhumba/indwangu yokuthamba nokumelana namanzi.

• I-ejenti yokugqoka iphepha ukuze kuthuthukiswe ubushelelezi nokumelana namanzi.

• Ikhemikhali yase-Oilfield (isb., uwoyela ongahluziwe uthela indawo ecindezelayo) ukuze ululame kangcono.

• I-3D yokuphrinta i-monomer yokuthuthukisa ukuguquguquka komkhiqizo kanye nezakhiwo zemishini.

Imibuzo Evame Ukubuzwa (FAQs)

Imibuzo evamile mayelana ne-LMA CAS 142-90-5:

Q1: Uyini umehluko phakathi kwe-LMA namanye ama-methacrylate monomers?

A: I-LMA iyi-monomer esebenza ngochungechunge olude eneqembu le-12-carbon lauryl, enikeza ukuguquguquka okungcono kanye nokuncipha okuphansi kunama-monomer ama-short-chain (isb, i-MMA). Igxile ekuguquguqukeni kunokuminyana okuxhumanisayo.

Q2: Indlela yokugcina LMA ukugwema polymerization?

A: Gcina ku-2–8℃ endaweni epholile, eyomile, engenamoya (isimo esingenamoya), esivalwe nge-polymerization inhibitor (isb, 300 ppm). Gwema ukushisa, ukukhanya, ama-oxidants neziqalisi. Impilo yeshelufu: izinyanga eziyi-12.

Q3: Ingabe i-LMA inobuthi? Yiziphi izinyathelo zokuphepha ezidingekayo?

A: I-LMA inobuthi obuphansi (i-LD50: amagundane angu-12000 mg/kg, amagundane angu-25000 mg/kg) anesikhumba esincane/eso. Gqoka amagiya okuzivikela, qinisekisa ukungena komoya, hashaza izindawo othintana nazo ngamanzi, gwema ukungenwa.

Q4: Ingabe i-LMA ingenziwa ngezifiso?

A: Yebo. Ukuhlanzeka (≥98.5% okujwayelekile, okuphakeme okutholakalayo), uhlobo/umthamo we-polymerization inhibitor, okuqukethwe umswakama kanye nenani le-asidi kungenziwa ngendlela efanele.

Q5: Kuyini ukupakishwa okujwayelekile kwe-LMA?

A: Okujwayelekile: 25kg/umgqomo noma 180–200kg/umphongolo (ovaliwe, umswakama-ubufakazi). Amaphakheji okuhlola amancane angokwezifiso ayatholakala.

Q6: Indlela ukuncibilika LMA?

A: Ayincibiliki emanzini; Incibilika kuma-alcohols, ethers, kuma-ketones. Faka i-solvent efanelekile ekamelweni lokushisa; gwema ukuxubana namanzi.

Q7: Ingabe i-LMA ingasetshenziswa ezinhlelweni zokudla/ezemithi?

A: I-LMA isetshenziselwa izimboni kuphela. Mayelana nokupakishwa kothintana nokudla, kufanele kuhlangabezane nezindinganiso ezifanele zokuphepha ukuze kugwenywe ukukhishwa okuyingozi.
