Qhov txawv ntawm Acrylic thiab iav

1. Qhov sib txawv ntawm cov khoom siv

(1) Acrylic, tseem hu ua plexiglass (Polymethyl methacrylate), abbreviated li PMMA, tshuaj hu ua polymethyl methacrylate, yog ib tug siab molecular polymer muab rho tawm los ntawm roj av. Acrylic muaj ntau yam khoom zoo ib yam li iav, tab sis acrylic muaj zog tiv thaiv thiab stability.

(2) Cov iav yog raug rho tawm los ntawm ntau cov silicate, lub ntsiab tivthaiv yog silicon dioxide, uas belongs rau inorganic iav.

2. Qhov txawv ntawm kev ua tau zoo

(1) Lub pob tshab ntawm acrylic yog siab li 97 feem pua, thiab nws qhov cuam tshuam tsis kam yog 17 npaug ntawm iav. Nws tsis yooj yim tawg, tab sis nws qhov hnyav tsuas yog ib nrab ntawm cov iav. Nws muaj cov xim zoo nkauj thiab tuaj yeem ua xim acrylic los ntawm kev ntxiv pigments.

(2) The transparency of the glass is comparable to that of acrylic, the hardness is higher than that of acrylic, and the scratch resistance is good; but it is easy to break, the impact resistance of ordinary glass is poor, and sharp fragments are easy to hurt people, but it can be processed and produced by special treatment. It can be made into a tempered glass and heat-resistant glass; if you need to make colored glass, you need to add a specific color of an inorganic salt or metal oxide in the production process, such as adding manganese dioxide (MnO₂) to turn purple, adding gold chloride (AuCl₃) turns red, etc.

3. Qhov sib txawv ntawm cov ntawv thov ua haujlwm

(1) Vim nws qhov kev cuam tshuam zoo heev, acrylic yog lub teeb, tiv taus kev poob thiab tsis yooj yim tawg, yog li nws yog siv ntau dua hauv kev kho kom zoo nkauj rooj tog, kev tshaj tawm sab nraum zoov, suab nrov teeb meem, teeb pom kev zoo npog, thiab lwm yam.

(2) Txawm hais tias iav yog qhov yooj yim tawg, nws yog qhov zoo dua li cov acrylic hauv ob qho tib si hardness thiab zoo nkauj, thiab iav muaj ntau yam khoom tshwj xeeb tshaj li acrylic, xws li refractory beakers siv hauv kev sim tshuaj, tsheb npav thiab siab - nce vaj tsev . Tempered iav, thiab lwm yam.

Yog li, tsis hais nws yog cov khoom siv, kev ua haujlwm lossis kev siv, peb tsis tuaj yeem cuam tshuam acrylic nrog iav. Acrylic yog cov yas tseem ceeb thiab belongs rau cov organic teeb meem; lub ntsiab ntawm iav yog oxide, uas yog ib qho inorganic non{0}}cov khoom siv hlau. Ob leeg muaj lawv qhov zoo thiab yuav tsum tsis txhob totaub.
