Kev nce qib tsis nyob twj ywm thiab txhawj xeeb txhua qhov ntawm tib neeg lub neej. Yog li nws yog nyob rau hauv kev tsim kho. Txhawm rau hloov cov thev naus laus zis qub, cov tshiab tag nrho tuaj, thiab cov khoom siv hauv tsev uas paub zoo thiab paub txog kev hloov kho tshiab lossis muab txoj hauv kev rau cov niaj hnub thiab siv tau ntau dua. Qhov no yog qhov tshwm sim nrog iav. Tsawg tus neeg yuav xav tsis thoob los ntawm ntau hom iav yas thiab qhov yuav luag tiav ntawm iav tsoos hauv khw.
Qhov txawv ntawm cov iav organic thiab iav inorganic
Los ntawm lub sijhawm tsis ntev los no, tib neeg tau kawm los tsim iav - pob tshab, khoom, thiab tseem ceeb tshaj plaws, cov khoom siv tiv thaiv tshav kub. Lub tsuas drawback ntawm tsoos iav, ua los ntawm tshwj xeeb npaj xuab zeb, yog brittleness. Nyob rau hauv lub xyoo pua 20th, kev tshawb fawb tau muab tib neeg cov khoom zoo ib yam rau cov iav inorganic thiab muaj peev xwm ua tau zoo ib yam hauv kev tsim kho - polymethyl methacrylate (PMMA). Ua ib qho yas, uas yog cov khoom siv organic, cov khoom tau nrov npe hu ua organic iav. Tom qab khaws tag nrho cov txiaj ntsig ntawm nws cov thawj coj, PMMA tau tshem tawm ntawm nws qhov teeb meem tseem ceeb -fragility.
Tsev tsim khoom
Tau txais polymethyl methacrylate raws li qhov tshwm sim ntawm polymerization ntawm methacrylic acid. Cov txheej txheem nws tus kheej yog qhov rov ntxiv ntawm cov ntsiab lus yooj yim tshaj plaws rau qhov nyuaj tshaj plaws. Qhov no yog qhov uas lub ntsiab feature ntawm PMAA qauv los ntawm - loj, nyob rau hauv sib piv nrog rau feem ntau inorganic tebchaw, molecules. Vim qhov kev tsim kho ntawm cov qauv no, daim ntawv organic iav yog qhov kev txiav txim ntawm qhov muaj zog dua li nws cov khoom siv inorganic.
Daim duab piav qhia tsis yog ib qho ua tau. Plexiglas yog tsim los siv tib lub tshuab siv lwm cov polymers. Piv txwv yog polystyrene, polycarbonate, thiab lwm yam.
Organic iav yog tsim raws li GOST 17622-72. Cov ntaub ntawv ua tib zoo sau tawm cov cuab yeej tsim khoom, raws li cov khoom tiav tom qab tau lees paub.
Qhov zoo ntawm PMMA
Outwardly, polymeric thiab inorganic fabrics yuav luag tib yam. Qhov txawv yog hnov nyob rau theem ntawm tactile hnov. Ua ntej, PMMA xav tias denser rau qhov kov. Qhov thib ob, organic iav yog ntau elastic. Kev tshuaj xyuas cursory ntawm lwm qhov sib txawv yog nrhiav tsis tau.
Qhov zoo ntawm plexiglass dhau qhov yooj yim silicate yog qhov tseeb. Lub zog ntawm thawj yog kaum npaug siab dua, zoo heev cuam tshuam tsis kam yog dhau qhov tsis ntseeg. Lwm qhov tseem ceeb ntxiv ntawm PMMA iav yog qhov zoo ntawm kev sib kis ntawm ultraviolet rays. Yog vim li cas cov panelsPolymethyl methacrylates yog nrov heev hauv horticulture, vim lawv yog cov khoom siv zoo tshaj plaws rau glazing tsev cog khoom. Kev tshawb fawb ntau ntxiv ntawm lub vev xaib polymer qhia ib qho ntxiv ntawm nws qhov zoo.
Nws tau raug tsim los tias thaum qhov kub nce mus txog 120 ° C, cov qauv ntawm cov iav polymer pib yaj, dhau los ua cov khoom khov thiab khov. Cov cuab yeej no nthuav dav cov peev txheej ntawm polymethyl methacrylate, vim tias cov yas no tuaj yeem siv tsis tau tsuas yog rau kev tsim cov Plexiglas panels, tab sis kuj rau lwm yam khoom. Lub tshav kub kub rau PMMA yog li ntawm 300 ° C, vim nws nyob rau hauv qhov kub ntawm qhov kub uas lub iav pib decompose.
Organic iav TOSP
Ib hom Plexiglas nrov tshaj plaws yog TOSP. Qhov no yog ib qho ntawm cov qauv ntawm polymethyl methacrylate, lub ntsiab feature ntawm uas yog lub xub ntiag ntawm ntxiv plasticizers nyob rau hauv lub molecular lattice. Qhov no feature muab plexiglass ntxiv txhua yam thiab lub cev zog. TOSP yog tsim nyob rau hauv daim ntawv ntawm monolithic blocks, uas ua rau kev thauj mus los, kev teeb tsa thiab kev ua haujlwm ntawm cov khoom yooj yim dua.
Siv cheeb tsam ntawm plexiglass TOSP
Hom iav organic no tau siv dav los ua cov khoom siv los sib sau ua ke ntau lub tsev. TOSP kuj pom nws siv hauv kev lag luam teeb ua khoom siv rau kev tsim cov thoob dej yug ntses thiab txhua yam khoom plig. Blocks muaj nyob rau hauv ntau yam xim variations, uas ua rau lawv ib tug heev nrov khoom rau kho kom zoo nkauj.khw qhov rais, pem teb kev tsim kho hauv khw malls, thiab lwm yam.
Cov khoom yog nrov heev nrog cov neeg lag luam. Feem ntau ntawm txoj kev hauv nroog koj tuaj yeem pom ib qho kev tshaj tawm uas tsim nyob rau hauv TOSP thaiv, lossis ib daim ntawv tshaj tawm hauv lub khw, tiv thaiv los ntawm cov pob tshab lossis ntau xim. Rooj tog manufacturers kuj tsis deprive lub innovation ntawm cov xim. Cov rooj kas fes niaj hnub no feem ntau yog tsim los siv thev naus laus zis siv cov iav zoo sib xws. Organic iav txee tau ua pov thawj lawv tus kheej zoo hauv tsev kho mob, thiab cov neeg tsim qauv tau siv cov khoom siv no ntxiv rau hauv kev tsim sab hauv ntawm ntau chav.
