Ukukhathala Okuphakathi Nokuhluka Kwe-Breakage
Ubunjingiqo Buka-Polycarbonate Bekugcinwa Emoyeni Ngaphandle Kwesilinganiso
Yini eyenza i-polycarbonate ibe namandla kangaka uma ishaywa? Inokuvumelana nezimo okuhle kwamangqamuzana okuyivumela ukuba imunce amandla amaningi lapho okuthile kuyishaya kanzima, njengokushaywa yisichotho esiphonsa ewindini noma amagatsha adilika esivunguvungwini. Kunokuba nje iqhekezeke, le nto iyagoba futhi yeluleke, isakaze amandla ize ichitheke ngokuphepha. Imfihlo iwukuthi lawo maketanga amade e-polymer ahlelwe kanjani ezingeni elincane, avumele ukuba ahambe ngaphansi kwengcindezi ngaphandle kokuba konke kuwohloke. Qhathanisa lokhu nezinto eziphukile eziqhekeka lapho zithintwa. Ngisho noma i-polycarbonate iklwebhuka ngokuhamba kwesikhathi, isahlala ihlangene kahle, yingakho isetshenziswa kakhulu ezindaweni ezinesimo sezulu esibi. Ukuhlolwa kuye kwabonisa ukuthi i-polycarbonate ingamelana nemiphumela enamandla ngokuphindwe izikhathi ezingu-250 kunengilazi evamile ngaphandle kokuqhekeka ibe izicucu eziyingozi. Futhi uthole lokhu kusebenza kahle noma ngabe izinga lokushisa lehla ngaphansi kuka-zero noma likhuphuka kakhulu ngaphezu kokubilisa. Lolo hlobo lokudlala lunengqondo ezindaweni lapho isimo sezulu esingabikezelwa siyingxenye yokuphila kwansuku zonke.
I-Glass Esheshayo Nempunge: Ukusheshwa Okulawulwayo Ngoko Kuyinkinga Yokuphangeleka
Ingilazi ehlanganisiwe ine-PVB interlayer egcina izingcezu ziboshwe ngemva kokuqhekeka, okuye kunciphise izingozi zokuqhekeka. Nokho, izingxenye ezinkulu zingase zize zikhululeke uma kunengcindezi eqhubekayo ngokuhamba kwesikhathi. Lapho ingilazi eqinile iphuka, iyaqhekeka ibe izingcezu ezincane kunokuba ibe izingcezu ezicijile, ngakho amathuba okulimala mancane kodwa ukuhlanza kuba yinhlekelele ngoba imfucumfucu isakazeka yonke indawo emhlabathini nasezingxenyeni, ikakhulukazi enkingeni ezibhedlela noma ezindaweni eziphithizelayo njengezikhungo Zombili lezi zinhlobo zihambisana namazinga abekwe ku-AS 1288 okukhetha nokufaka ingilazi, kodwa ayikho ephephile ngokuphelele ngenxa yobuthakathaka obuthile. Izinto ezicijile zisengabahlaba, futhi ingilazi eqinile ngezinye izikhathi iyaqhuma ngaphandle kokuxwayisa ngenxa yezinhlayiya ze-nickel sulfide ngaphakathi. Izinhlobo ezihlanganisiwe nazo ziyalimala ngenxa ye-UV eminyakeni eminingi, okwenza ungqimba lwangaphakathi luwohloke kancane kancane. Ezakhiweni eziseduze nezindawo ezinemililo, kufanele kufakwe izingqimba ezikhethekile ezingamelana nomlilo engilazini ehlanganisiwe ukuze ingancibiliki lapho izinga lokushisa lidlula u - 120 degrees Celsius. Nokho, ukuhlolwa okuvamile kuyadingeka ngempela, ukuze kutholakale izimpawu zokuqala zokuphazamiseka ngaphambi kokuba ukwehluleka kwesakhiwo kwenzeke endaweni okungalindelekile ukuthi kuzokwenzeka kuyo.
Ukuxhamela kwezibopho zokuphepha kumakhambi amakhasi nezindawo eziphathelene nokuhlukunxa
AS 1288, AS 3959, nezidinga zeBushfire-Zone yezilanga zePolycarbonate nezilanga
Amathuluzi ebandla kumakhanda okhathalekayo ekuthuthukisweni kungasebenzi kahle xa kuthulwa yizinkunzi ezihlaza emuva, ukugena kwesimilo esiningi kuyafika ku-40 kW ngamitholobala, nokudamageka ngezinto ezibuyiselwa yizulu elinamandla. Amavili okufakwa njenge-AS 1288 ne-AS 3959, owenziwe ngokuphathelene nokwakha kumakhanda okhathalekayo ekuthuthukisweni, ayavikela izicelo eziphethemba ngokuba izigaba zisebenze kulezi zimo eziningi. Isampula se-polycarbonate asidali phakade futhi isetshenziswa kakhulu lapho ubude buhamba kangaka 120 degrees Celsius, ngakho kusebenza kahle kumakhanda okhathalekayo ekuthuthukisweni engasohlaziywa. Igilasi eqhudwa kudinga amalayini amaningi angaphendukwa ukuze afakwe kumakhanda okhathalekayo ekuthuthukisweni. Abawekeli baphepha lezi zici ngokulinganisa ukuthi bezifaka kanjani isimilo, ukuthi izinkunzi zingena kanjani, futhi ukuthi zingasebenzi kanjani ngemuva kokuthi zithulwe ngokushesha kakhulu. Lezi ziphepho zisenza sikhumbula ukuthi amakhanda asebenze kahle ekuphileni kumadoda emehlweni.
Izindinganiso ze-OSHA, NFPA, ne-ASTM E1886/E1996 zezinsalela ezibangelwa umoya
Ezakhiweni ezisetshenziswa kwezentengiselwano lapho iziphepho zivame khona, ukulandela imithetho ye-OSHA yokuvikela ukuwa kanye nemihlahlandlela yokuphepha ye-NFPA 5000 kuyadingeka ngokuphelele. Ukuhlolwa kwe-ASTM E1886 ne-E1996 ngokuyisisekelo kubuyisela lokho okwenzekayo phakathi neziphepho ngokudubula izinhlamvu zokhuni ezingamakhilogremu angu-9 ezindaweni ezihamba ngamakhilomitha angu-50 ngehora. Izinto ze-polycarbonate zivame ukumelana kahle nalezi zingozi ezinkulu ngaphandle kokuphuka ngenxa yokuthi ama-molecule azo aguquguqukayo ezingeni elincane. Ingilazi eqinile isebenza ngendlela ehlukile nakuba idinga izingqimba ezikhethekile ezihlanganisiwe ukuze izingcezu zingabi sezindiza nxa zishaywa. Izindinganiso eziyinhloko zokudlula kulezi zivivinyo zihlanganisa amamethrikhi amaningi abalulekile okusebenza anquma ukuthi izinto zihlangabezana yini nezindinganiso zokuphepha ezimweni zezulu ezimbi kakhulu.
| Standards | Ukugxila Kokuhlola | Isilinganiso Sokuphumelela |
|---|---|---|
| I-ASTM E1886 | Ukulayishwa kwengcindezi okujikelezayo | ukuvuza komoya ≤15% |
| I-ASTM E1996 | Umthelela Wemfucumfucu Eqhutshwa Umoya | Akukho ukungena emgodini ≤3" |
| NFPA 101 | Ukuphila Kwesimilo Kwezimali | ukukhuseleka kwezinyanga ezimbi-90 |
Izilanga ezifakwayo emazone ehuwisi ezigunyazwe ngezinyanga-3–5 zidinga ukutholakala kwebhizinisi lokuphathelene nokuthuthukisa kwalokhu kumazwi amandla.
Ukuphila Kude Kwezimali: Ukuchwepeshwa, Ukuphatha, Nenxenye Yempilo
Ukuthuthukisa Kwe-UV, Ukukhuseleka Kwezishushu, Nokubomvu kwePolycarbonate Ngaphandle Kokucindezeka Ngokushisa KweGlass
Imiphakathi emikhulu yeziphaneli ze-polycarbonate ngokwehla kwesikhashana kungaba ngumhla kuqina kwe-UV kanye nokuthuthwa kwesihlangothi. Iziphaneli ezingenazo iico ngezikhathi zingavulela ngaphezulu kwesikhathi ngemva kumnyaka engu-10 uma kuthiwe ngemikhambi yokulima. Ngokubaluleka okungaphansi kwalokhu, ngaphandle kokuthuthwa kwezinye izikhathi ezijulile kungakwenzeka. Lokhu kungase kungabonakala ngokukhulu ngokuqala, kodwa kuyenzela ukuthi iglasi ibe yinxenye yokubanda kanye kungakwenzeka ukuthi kuthuthwe ngokushesha uma kungaphathelene. Iziphaneli ze-glass zinezici ezithile. Zilondela kahle kwiqina le-UV, kodwa izinkinga zokuthuthwa ngokwesitha zilisebenza. Uma izinye izingxenye zeglasile zibukele kanye nezinye zilinde emoyeni, lokhu kuyenzela ukutha kwezinkwa ngaphezulu kwe-35 degrees Celsius noma 95 Fahrenheit. Lokhu kuyenzela ukuthuthwa okuncinci kweglasile ephinde kuyenzela ukuthuthwa okubonakalayo, ikakhulu apho ukubukele kwezinkwa kuthinta ngokwehla kwesikhashana.
| Impahla | Ingxenye Yokugcinwa | Ukufuna Ukulungisekile | Ukuphakama kweqondo |
|---|---|---|---|
| Polycarbonate | Ukugulwa kwe-UV kanye nokugunyaza kwezinye | Ukufaka kabusha kwesilinganiso ngonyaka | Ukuncipha kokuwela kwamandla |
| Iglass | Ukuhlupheka ngenqubekela yethirmali | Ukuhlola kwesilinda phakathi komnyaka | Ukuphila okuphambene kwegcobo |
Ukuphatha kahle kubaluleke kakhulu xa kusekelwa lezi zimboni. Kudingeka ukuba isilinganiso se-UV sibuyiselwe kupolycarbonate ukuze sibe nemini ephindele, ngelixa izihlangothi ze-glass zidinga ukulunga kwazo ukuthi zixhomeke njani ezinguquko zentempeli kanye ukuthi izilonda zizolungile ngokuphakade. Izivikeli ezasekhaya zibonisa into ethintekayo futhi: ipolycarbonate eqhakazwayo kahle isebenza ngaphezu kwesibili emva kwezingu-15 kunaglasu enjalo. Kodwa makahlale siyashisa, uma simemeza konke lokhu, kuzothutha ngokushesha. Ngakho-ke ukulanda ekhono lokuphatha kahle akuyilapho kuphathelwano kuphela kodwa kunciphisa imali kanye kuvikelapha bonke ngokudla okude.
Imibuzo Evame Ukubuzwa
- Yini eyenziwa kupolycarbonate ibe yanelise izishiselayo? I-polycarbonate inemitholobaleni ye-molecule ezingenakho ukuthutha kusiko ngokuthatha amandla ngemvuthi, ukukhulula kuthutha njengemitholobaleni epholile.
- Ukugcina okulamulelwe kuhluke kanjani kuka ukugcina okukhokhelwe? Ukugcina okulamulelwe kugcina amagonyana athunywa ngaphakathi kwe-PVB, ukuthulasela kwezithixo ezilondelayo, ngelinye izindawo ukugcina okukhokhelwe kuthunywa kumagunyana.
- Izinkomba ze-polycarbonate zihle noma angini ngezindawo zokuphaya? Yebo, izinkomba ze-polycarbonate ziyastabile noma kuphela uma ubude buhla kungaphezulu kuka-120 degrees Celsius, ukuthi kuzihle kuzindawo zokuphaya e-BAL-40.
- Kutheni ukulungiselelo kufunekayo kwezinkomba ze-polycarbonate? Izinkomba ze-polycarbonate kudinga ukubhoshwa ngonyaka ukukhulula kwebhoshwa yama-UV nokugcina okugcina okugcina.
- Kuthini okufuneka kujwayele ukulindela kwezinkomba zegcina? Izinkomba zegcina kufuneka kujwayele ukulindela kwegunyana ngaphesheya kwesibili ukukhulula kwebhoshwa yegunyana.
