Peb txhua tus cuam tshuam nrog iav txhua hnub-qhov rais, lub tsheb cua, thiab txawm tias lub khob kas fes uas ib txwm zoo li tau txais ntiv tes rau ntawm nws. Tab sis tom qab ntawd koj taug kev mus rau hauv lub khw muag khoom kho vajtse lossis lub chaw txhim kho tsev thiab pom qee yam ci ntsa iab, du, thiab hnav: Plexiglass. Tej zaum koj yuav xav tias, "Plexiglass tawv dua li iav li niaj zaus? Nws puas yuav tawg yooj yim dua? Yuav ua li cas yog tias kuv poob los yog tsoo rau hauv nws?"
Zoo, hnub no peb tab tom dhia mus rau hauv lo lus nug no nrog qee qhov kev tshawb fawb, cov ntaub ntawv, thiab kev lom zem. Yog li lob koj cov dej haus uas koj nyiam, thiab cia peb tawg qhov no (piv txwv!).
Plexiglass yog dab tsi?
Ua ntej peb tham txog yuav ua li cas nyuaj Plexiglass, cia peb paub tseeb tias nws yog dab tsi. Plexiglass yog qhov tseeb lub npe rau cov khoom siv paub txog kev tshawb fawbacrylic ximlos yogPMMA (Polymethyl Methacrylate). Nws yog ib qho hluavtaws polymer uas siv los ua lub teeb yuag, tawg-resistant lwm txoj rau iav. Xav txog nws li yas uas zoo li iav. Tej zaum koj tau pom nws hauv cov duab thav ntawv, cov paib, lossis txawm tias yog qhov hloov pauv rau iav hauv qee qhov rais.
Tam sim no, cia peb saib yuav ua li cas Plexiglass stacks tiv thaiv iav tsis tu ncua thaum nws los txog rau kev ua haujlwm ntev thiab tiv thaiv kev tawg.
Cov hauv paus ntsiab lus: Lub iav tsis tu ncua li cas?
Ordinary iav, txawm tias nws yog hom siv hauv koj lub qhov rais lossis lub qhov rais ntawm koj lub tsheb, yog ib daim ntawv ntawmsilicate-Qhov sib xyaw ntawm cov xuab zeb, dej qab zib, thiab txiv qaub, rhuab mus rau qhov kub thiab txias, tom qab ntawd txias los ua ib qho khoom, nkig. iav yognyuaj-lub ntsiab lus nws resists khawb-tab sis nws kujnkaws-lub ntsiab lus nws tuaj yeem tawg lossis tawg yooj yim hauv kev cuam tshuam.
Lub brittleness ntawm iav txhais tau hais tias thaum nws raug ntaus nrog lub zog txaus, nws tawg mus rau hauv ntse, txaus ntshai shards. Yog li, thaum iav yog qhov zoo ntawm kev tuav txhua hnub hnav thiab tsim kua muag, nws muaj nws qhov txwv. Piv txwv li, tus qauvtensile zogntawm iav (tus nqi ntawm lub zog nws tuaj yeem tiv taus ua ntej tawg) feem ntau nyob ib puag ncig40 MPa(Megapascals), uas txhais tau tias nws yuav tsis noj ntau dhau ua ntej nws tawg.
Thiab dab tsi txog Plexiglass?
Tam sim no, cia peb tham txog Plexiglass (acrylic). Tsis zoo li iav, Plexiglass yoghloov tauthiabcuam tshuam-resistant. Nws yog lub npe hu ua10-24 lub sij hawm cuam tshuam ntau duadua li iav. Yog li, koj tuaj yeem xav txog tias nws nyuaj npaum li cas thaum koj tso nws los yog ntaus nws tawm tsam qee yam nyuaj.
Qhov zais cia rau Plexiglass lub zog nyob hauv nwsmolecular qauv. Thaum lub iav muaj qhov nruj, nruj sib txuas cov qauv molecular, Plexiglass muaj qhov hloov tau yooj yim dua, me ntsis "stretchy" molecular saw. Qhov no ua rau nws tsis tshua muaj kev tawg thiab feem ntau yuav khoov me ntsis hauv qhov siab, faib lub zog ntau dua.
Raws li lub zog tensile, Plexiglass tuaj nyob ib puag ncig70-90 MPa, nyob ntawm qhov tseeb formulation. Tus lej siab dua no txhais tau tias nws tuaj yeem nqus tau ntau dua ua ntej tawg piv rau iav. Yog li, yog tias koj tso ib daim ntawm Plexiglass, nws yuav muaj ntau duadent los yog khawbtshaj li tawg mus rau hauv ib txhiab daim.
Kev sib piv ntawm lub neej tiag tiag: Plexiglass vs. iav
Okay, yog li Plexiglass zoo li nyuaj, tab sis cia saib seb nws ua tau li cas hauv ntiaj teb tiag. Xav txog tias koj yuam kev tsoo ntawm daim duab ncej-ib qho ua los ntawm iav tsis tu ncua thiab lwm qhov ua los ntawm Plexiglass.
Lub iav Frame:Nrog lub khob zoo lossis lub caij nplooj zeeg, lub iav thav duab zoo li yuav tawg mus rau hauv cov khoom ntse, tsim kom muaj kev ntxhov siab (thiab, nyob ntawm seb koj mus qhov twg, kev raug mob). Qhov no yog qhov poob ntawm iav-ib zaug qhov kev ncaj ncees raug cuam tshuam, nws tawg sai thiab nyuaj.
Plexiglass Ncej:Thaum koj khob nws dhau, Plexiglass ncej yuav zoo likhoovlos yogkhoov, tab sis nws yuavtsis tawg. Qhov tseeb, yog tias koj muab nws lub zog kais, tej zaum koj tsuas yog pom qhov tawg me me los yog qhov dent, tab sis tsis muaj cov npoo ntse los txhawj txog. Nws yuav luag zoo li tus ncej yas hais tias, "Hav, Kuv tuaj yeem nqa nws, tsis muaj teeb meem."
Cov ntaub ntawv thiab kev sim: Plexiglass muaj zog npaum li cas?
Txhawm rau ua kom muaj kev tshawb fawb me ntsis, cia peb tham txog qee qhov kev sim tiag tiag.
Impact Resistance:Hauv ib qho kev xeem paub zoo, ib daim Plexiglass nrog lub thickness ntawm 3 hli raug ntaus nrog lub pob hlau. Nwstsis tawg- nws nkaus xwbkhoov. Muab piv nrog cov iav tsis tu ncua ntawm tib lub thickness, uas yuav tawg ntawm qhov cuam tshuam.
Ball Drop Test:Nyob rau hauv ib qho kev sim pob poob, qhov twg lub pob hlau poob los ntawm qhov siab, Plexiglass nthuav tawm qhov ua tau zoo dua, nrog rau kev ua haujlwm zoo dua.tsawg tus nqi tawg. iav? Tsis ntau. Nws nyiamtawgnyob rau hauv cov xwm txheej zoo sib xws.
Kub Resistance:Plexiglass kuj zoo dua hauv qhov kub thiab txias. Nws tuaj yeem tiv taus qhov kub thiab txias xws li-40 degree rau 90 degree (-40 degree F txog 194 degree F)tsis muaj cracking, whereas iav tuaj yeem ua rau muaj kev cuam tshuam ntau dua hauv kev hloov pauv kub ceev (xav txog lub khob kub ntawm lub khob txias txias).
Qhov zoo thiab qhov tsis zoo ntawm Plexiglass vs. iav
Cia peb xaus qhov zoo thiab qhov tsis zoo ntawm txhua yam khoom:
| Feature | Plexiglass (Acrylic) | iav |
|---|---|---|
| Impact Resistance | 10-24 lub sij hawm cuam tshuam ntau dua | shatters yooj yim nyob rau hauv kev cuam tshuam |
| Tensile zog | Siab dua (70-90 MPa) | Tsawg (40 MPa) |
| Qhov hnyav | Lub teeb thiab hloov tau yooj yim dua | Hnyav dua, nruj dua |
| Scratch Resistance | Ntau zaus rau khawb | Tsawg nquag, tab sis tawg yooj yim |
| Kub Resistance | Kev tiv thaiv zoo rau qhov kub thiab txias | Yooj yim rau thermal shock |
| Nqi | Feem ntau kim dua | Feem ntau pheej yig dua |
Yog li, Puas yog Plexiglass nyuaj dua los tsoo dua iav?
Lo lus teb yog ib qho resoundingyog. Plexiglass yog qhov hnyav dua li iav li niaj zaus thaum nws los txogcuam tshuam tsis kam. Nws tsis tsuas yog nyuaj rau kev tawg tab sis kuj muaj kev nyab xeeb dua vim tias nws tsis tawg mus rau hauv cov phom sij txaus ntshai. Nws khoov, dents, thiab absorbs poob siab zoo li champ.
Tab sis, cia peb meej-Plexiglass tsis yog invincible. Nws tseem tuaj yeem raug khawb (tshwj xeeb tshaj yog nyob rau sab nraum zoov lossis chaw tsheb loj), thiab nyob rau hauv qhov xwm txheej hnyav, nws tuaj yeem tawg lossis tawg. Txawm li cas los xij, rau kev siv txhua hnub, tshwj xeeb tshaj yog qhov kev nyab xeeb lossis kev ruaj ntseg yog kev txhawj xeeb, Plexiglass feem ntau yog qhov kev xaiv zoo dua.
Yog li, lwm zaus koj tab tom xaiv ntawm Plexiglass thiab iav rau koj qhov project, nco ntsoov: nws tsis yog qhov zoo nkaus li - nws yog hais txogtawvib yam!
Vam tias koj yuav txaus siab rau qhov kev tawg no! Yog tias koj muaj lus nug ntxiv txog Plexiglass, iav, lossis lwm yam, thov hu rau dawb. Thiab nco ntsoov: seb nws yog Plexiglass lossis iav, tsis yog cov khoom nyiam raug poob, yog li cia peb sim ua kom ob leeg tawm hauv pem teb, ua li cas?
