Puas yog Methyl Methacrylate (MMA) kua siv los ua Acrylic Plastics?

Taw qhia

Methyl methacrylate (MMA) yog qhov tseem ceeb monomer tom qab acrylic plastics, resins, coatings, thiab adhesives siv thoob plaws kev tsim kho, tsheb, hluav taws xob, thiab kev kho mob kev lag luam. Chemically, MMA yog ib qho unsaturated ester uas polymerizes rau hauv poly (methyl methacrylate), zoo dua hu ua PMMA los yog acrylic iav.

Phau ntawv qhia no piav qhia tias MMA monomer yog dab tsi, nws lub cev thiab tshuaj lom neeg, nws hloov mus rau acrylic yas los ntawm polymerization li cas, thiab cov neeg yuav khoom yuav tsum nrhiav dab tsi thaum nrhiav kev lag luam - qib MMA.

Methyl Methacrylate (MMA) yog dab tsi?

Methyl methacrylateyog ib qho organic compound teej tug mus rau methacrylate ester tsev neeg. Nws yog tsim los ntawm esterifying methacrylic acid nrog methanol thiab yog qhov zoo tshaj plaws hu ua monomer siv los tsim PMMA.

MMA cov qauv molecular muaj cov pa roj carbon reactive -carbon ob daim ntawv cog lus, uas tso cai rau ib tug monomer units los txuas ua ke mus rau hauv lub polymer ntev chains thaum lub sij hawm polymerization - cov tshuaj hauv paus rau acrylic yas ntau lawm.

Puas yog MMA ua kua?

Yog lawm. Nyob rau hauv chav tsev kub, methyl methacrylate yog:

• A ntshiab, xim tsis muaj kua
• Volatile, nrog ib tug ntse, yam ntxwv tsw
• Flamable, yuav tsum tau ceev faj cia thiab tuav
• Tsawg viscosity, ua kom yooj yim rau ncuav, sib tov, thiab txheej txheem

Lub xeev cov kua dej no tsis yog xwm txheej - nws yog qhov tseem ceeb rau kev siv MMA li cas hauv kev lag luam. Tsawg -viscosity kua monomer yog:

• Yooj yim sib tovnrog cov neeg pib, hla -linkers, thiab lwm yam monomers los txiav cov qauv resin
• Yooj yim rau polymerizenyob rau hauv bulk, tov, ncua kev kawm ntawv, los yog emulsion txheej txheem
• Haum rau resin ntau lawm, tso cai rau cov tuam txhab pov npav, pwm, lossis cov ntaub ntawv txheej ua ntej cov polymer solidifies

Hauv luv luv, MMA daim ntawv ua kua yog dab tsi ua rau nws ua tau - PMMA khoom tsis tuaj yeem ua raws li cov kua MMA monomer ua ntej polymerization.

Physical and Chemical Properties of MMA

Cov khoom no ncaj qha cuam tshuam rau kev tuav tuav: qhov qis qis txhais tau tias MMA yuav tsum tau muab cia kom deb ntawm qhov chaw hluav taws xob, thaum nws cov kuab tshuaj miscibility ua rau nws sib xws nrog ntau hom resin thiab txheej txheej.

Yuav ua li cas MMA siv los ua Acrylic Plastics?

MMA Polymerization txheej txheem

Acrylic yas yog tsim los ntawm kev hloov cov kua MMA monomer rau hauv cov khoom polymer los ntawm cov saw - cov txheej txheem tshuaj hu ua polymerization:

MMA Monomer

↓

Polymerization (initiator + tshav kub / UV)

↓

PMMA (Poly Methyl Methacrylate)

↓

Acrylic yas khoom

Thaum lub sij hawm polymerization, ib tug pib ua rau ob daim ntawv cog lus nyob rau hauv txhua MMA molecule qhib thiab txuas nrog cov nyob sib ze monomer units, tsim ntev polymer chains. Raws li cov tshuaj tiv thaiv zoo zuj zus, cov kua monomer solidifies rau PMMA - ib qho tawv, pob tshab thermoplastic.

Cov yam ntxwv tseem ceeb ntawm PMMA:

• Siab pob tshab- lub teeb xa hluav taws xob ntau dua 90%, piv rau iav
• Lub teeb- kwv yees li ib nrab ntawm qhov ntom ntawm iav
• UV tsis kam- ruaj khov nyob rau hauv lub hnub ci ntev tsis muaj yellowing
• Huab cua tsis kam- haum rau ntev - siv sab nraum zoov
