Qhov Ntev Ntawm Plexiglass: Tuab 1-4 Thiab 5-8, 16-16 Thiab 20-30 Hli, Lwm Yam, Ntom Ib M3 Thiab Qhov Hnyav Ntawm Daim Ntawv Acrylic

Plexiglass (polymethyl methacrylate) tau tsim los ntawm tus kws tshawb fawb German Otto Rau . TAB SIS kev tsim cov khoom siv tau pib xyoo 1933 … Tam sim no nws tau nrov nyob hauv ntau yam haujlwm: kev tsim kho tshuab, tsim kho, tshuaj, kos duab thiab tsim qauv.

Peculiarities

Cov iav organic (PMMA) raws li GOST cov qauv tsim hauv ob hom:

• TSO - cov yas yas tau ntxiv rau cov khoom siv, vim tias nws lub cev thiab cov khoom siv tau zoo tuaj. Cov khoom siv tau yooj yim tuaj pwm. Nws yog siv rau kev tsim cov txheej txheem nyuaj, ntim khoom, khoom plig. Qhov sib txawv tseem ceeb yog qhov dav xim palette.
• TOSN - plexiglass tsis muaj yas yas. Tiv taus kev hloov pauv kub thiab tshuaj lom neeg sai. Xim - pob tshab, ua hauv cov blocks.

Qhov zoo ntawm cov iav acrylic:

• lub zog - nws tsis yooj yim los rhuav nws thaum piv nrog iav ib txwm, yog li ntau yam pib tsim los ntawm acrylic;
• yooj yim ntawm kev ua - cov cuab yeej muaj txiaj ntsig zoo rau kev tsim: cov khoom tuaj yeem siv rau hauv cov ntawv uas txawv tshaj plaws;
• lub cev hnyav - nws dhau los ua yooj yim dua txav cov iav no;
• pob tshab - txawm tias cov khoom xim muaj qib siab ntawm pob tshab.
• ya raws tsis kam - cov khoom tiv taus tsis tsuas yog dej, tab sis kuj tseem muaj ntau yam tshuaj lom neeg.

Raws li txoj kev tsim khoom, cov iav organic tuaj yeem muaj ntau hom

• Extrusion (qis molecular hnyav) … Nws yog tsim los ntawm txoj hauv kev txuas ntxiv txuas ntxiv ntawm cov khoom tiav los ntawm kev sib sau extruder. Tom qab ntawd cov workpieces tau txias thiab txiav rau hauv nplooj ntawv ntawm qee qhov ntau thiab tsawg.
• Txhaj tshuaj molding (siab molecular hnyav) . Cov khoom siv no muaj cov yam ntxwv zoo dua li iav extrusion. Nws muaj qhov ua kom du thiab pob tshab, poob siab thiab tawg tsis kam. Tiv taus qhov kub thiab tsis raug rau tshuaj. Nws yog tsim los ntawm nchuav cov kua ua kua nruab nrab ntawm ob lub dav hlau nrog ntxiv dag zog.
• Ntawv . Txhawm rau ntxiv huab cua los yog lub teeb tawg, polystyrene muaj nyob hauv qhov muaj pes tsawg leeg. Lub peev xwm xa lub teeb sib txawv ntawm 25 txog 75%.

Cov iav iav, tig mus, tau muab faib ua cov kua nplaum ci thiab satin plexiglass.

Thickness

Cov ntawv tuab tuaj yeem sib txawv ntawm 1 txog 30 hli. Qhov kev thov ntawm PMMA tseem yuav hloov pauv los ntawm qhov ntsuas no . Nyias acrylic iav 1 hli siv rau kev tsim cov cuab yeej kho qhov muag, saib lub xov tooj thiab lwm yam khoom lag luam. Khoom tuab 2 hli nrov nyob rau hauv kho kom zoo nkauj thiab sab hauv tsim, haum rau ua ntau yam ntxhuav thiab sawv.

Plexiglas 3 hli, 4 hli, 5 hli, 6 hli, 8 hli thiab 10 hli tuab dav siv hauv kev siv tshuab, aviation, kev lag luam rooj tog. Los ntawm iav 12 hli vs 16 hli koj tuaj yeem tsim ntaiv, muab faib. Thiab cov tuab 20 hli thiab yog qhov tsim nyog tshaj rau kev tsim cov pas dej ua ke thiab lub qhov muag.

Ntawv qhov ntev

Plexiglass tau tsim tawm hauv ntau qhov kev hloov kho: ntawv, pas nrig, thaiv, kav dej thiab lwm yam khoom lag luam. Cov ntawv txheeb thiab cov khoom thaiv feem ntau yog ua los ntawm daim duab plaub. Qhov loj me me yog 125x115 cm, 160x140 cm, 205x305 cm.

Ceev thiab hnyav

Qhov ntom ntawm plexiglass, nyob ntawm hom khoom, tuaj yeem sib txawv ntawm 1.1 txog 1.2 g / cm3 , tab sis lub neej ntawd ib txwm yog 1.2 g / cm3. Kub ntau - los ntawm -60 txog + 100 ° C. Cov khoom siv no tsis siv hluav taws xob thiab cua sov, yog li nws tuaj yeem siv tau ua hluav taws xob thiab cov cua sov. Vim nws qhov hnyav tsawg, plexiglass tau pib siv nyob rau ntau qhov chaw . Thaum kho chav thiab lwm thaj chaw, cov khoom siv tsis hnyav hnyav rau ntawm qhov chaw, uas yog qhov tseem ceeb rau cov tsev nyob hauv cov tsev siab. Thaum cov iav tsom iav, tsis tsuas yog qhov pom kev, tab sis kuj tseem muaj zog ntawm cov khoom siv ua lub luag haujlwm tseem ceeb.

Dhau li, qhov hnyav ntawm PMMA ncaj qha nyob ntawm seb hom khoom siv thiab txheej txheem ntawm nws cov khoom siv … Piv txwv li, iav extruded hnyav 15-20% tsawg dua li cov cam khwb cia sib piv. Plexiglas hnyav 2.5 npaug tsawg dua iav zoo ib yam nrog qhov ntev, dav thiab tuab ntawm daim ntawv, ua los ntawm cov xuab zeb quartz. Piv txwv li, iav silicate nrog qhov ntev 120x200 cm muaj qhov hnyav ntau dua 7 kg, thiab iav acrylic - 3 kg.

Thaum siv txhua hom thaiv polymethyl methacrylate, cov mis hauv qab no tuaj yeem siv los xam qhov hnyav:

TxWxDxP = qhov hnyav (g),

qhov twg T yog tuab (hli), W yog qhov dav (hli), D yog qhov ntev (hli), P yog qhov ntom ntawm cov khoom.

Piv txwv, plexiglass nrog qhov ntsuas 20x800x800 mm, muaj qhov ntom ntom ntawm 0.0012 g / mm3, yuav hnyav:

20x800x800x0.0012 = 15360 g (15, 36 kg).

Thaum suav, nws yog ib qho tseem ceeb kom nco ntsoov tias txhua qhov txiaj ntsig yuav tsum nyob hauv tib chav.
