Ukuhlanza Kwesikhumba Se-Polycarbonate: Ukuzimisela Kwezinkambo Zokuphepha

Ukuthi I-Polycarbonate Sheet Inqamuka Kanjani Ekupheleni Kwezilwanyana: Ukuphakama, Ismoke, Nokuthi Kwemifula Yekuphakama

Imiphumela Yezimboni Zokuphakama Nokuthi Kwemifula Yekuphakama Ngaphansi Kokubonwa Kwesilwanyana

Izilayethi zesiPolycarbonate aziyikhi futhi kahle, kodwa zihlukana ngendlela efanele uma zibhekwa ngomoya wemvula. Umkhakha uqala ukufana ngokwesikhathi esingama-300° Celsius (ngokwesibonelo isikhathi esingama-572 Fahrenheit) futhi luhambisana ngaphandle kwezithakazelo zomoya. Lokhu kwenza indlela yokubeka izinkambo ezingaqinisekileyo ezinokuvimba umoya, okuyinto ekhathazisa indlela yokuphuma kwemvula ngokushesha. Kodwa uma umoya uyakhupha ngokushesha, izinto zihlukana ngokushesha njengoba iplastiki ethuluzi liyadlula ngaphansi. Indlela yokuthuluzwa iyiphinda iyiphinde yinkimbinkimbi yezilayethi. Izilayethi ezincinci zokugcina izinsuku ziyahamba zonke uma zibhekwa ngomoya, ngakho-ke izilayethi eziningi ezizindawo ziyabona kahle kunezilayethi zokugcina izinsuku uma zibhekwa ngomoya. Uyazi isilayethi sezinkambo esingama-12mm, lokhu sibonisa ukuthi kuyasebenza kabusha emva kokuba kusobala kabanzi kunezilayethi zokugcina izinsuku uma kusobalwa ngomoya ngokusebenzisa imithombo yezifundo zokuxhasa.

Indlela Yokuphuma Kwemvula (SDI) Nobuchwepheshe Bokuthi Kuzoba Yini Ngeminye Imizemo Yezinhloso

Kodwa kufikile ekubeni kubhala, ikarbo-nayitride ibonakala ngokwezinye ngoba iyapha amafutha angaphezu kwezincani. Le mithombo yisahlukane kusuka emva kwe-ASTM E84 Smoke Development Index ngaphansi kwe-200, okuyisahlukane kakhulu kwezinye izinto ezinamathilika ezenziwa ngamathilika kanye nezinye. Kuzoba kanjani xa ikarbo-nayitride ishisa? Ngokuvamile kusho ukuthi kusha kuphela i-carbon dioxide nezibonakaliso zemvula. Futhi lapha kukhona okunempilo—akukho kungaphezulu kokuphakanyiswa kwamagasi amangcono njenge-hydrogen cyanide noma i-carbon monoxide, ngokuhambisana nesikhathi esingasemthwakathini noma i-polystyrene. Izifundo zibonisa ukuthi futhi kumashishini okugcinwa, amafutha ayabeka ngaphansi kwe-15% yokungabonakali kusukela kuqala. Ngaphezu kwalokho, ikarbo-nayitride ishisa ngokwakho uma izimboni zishisa zihlala. Lezizindlela ziyabonisa ukuthi abantu baba nokubona kahle uma badinga ukususa kahle, futhi babenakho imiphumela engaphezulu yokudlala amagasi amangcono.

Isimo Sokudala Kwamadropile Nokuthi Sibonakala Kanjani Ekushisweni Kwezinkundla

Ukudlula kwe-polycarbonate esihlukile ekuseni kwenza izinkinga ezingaphezulu kubuhlebujule bokuphakama kwemoto ngokuvuza, ikakhulukazi emaphakathini amaningi, emaphakathini okuphakama, nasezindaweni eziningi zezindlu. Uma izintemperatura ziphakamisa kakhulu, lezi zibhombiso zomoto zizokuvusa izinto ezisemzini, okuzovusa ukuphakama kwemoto ngokushesha kunezinhloso zokuphakama. Umthwalo we-UL 94 VB uqondisa ukuthi le nkosinga iyiphi indlela enkulu. Izinkotho zokuvusa okunjalo zokugcinwa ziyavuseka ukuthi ziyabona izibhombiso ezivusa ezingu-5 kuphakade njengoba kubonakala kule miyalelo. Ukuxhasa le nkosinga, izindlela eziningi zinamandla njengokubambisana. Ukufaka izibhombiso ngokuvuza nokubeka izibhombiso zokugcina izibhombiso ziyakunceda ukuthi zilungiselele le nkosinga. Ukudibanisa i-silica kubumbeko bekho kuyenza ukuthi kubheke kakhulu uma kusihlukile, okunciphisa isivumelwano sokudlula kwezibhombiso ezinjalo. Kuyisidingo sokuhlukanisa izihlangothi zokugcinwa zokuphakama ngokuvuza ngokuphakade zingaphezu kwe-3 mita emazini apho inkosinga ibe enkulu. Lezi zindlela zonke zizobonakala zinamandla kubuchwepheshe, zikunciphisa ukuvusa kwezibhombiso ngokuphakade ngo-70% kubuchwepheshe obubalulekile.

ASTM E84/UL 723 vs. EN 13501-1: Ukuphakanyiswa Kwezinyoka, Isikumbi, Nokuhlinzekwa Kokuhlinzeka

Imistandare yokuqonda ukuthi izinto ziyasebenza njani emthwakathini, i-ASTM E84 (okwenzekwa ngokubizwa nge-UL 723) ne-EN 13501-1, zihlukaniswe kakhulu. Ngokusebenzisa i-ASTM E84, bavula umlando wokuzama okubizwa ngokuthi ‘umlando wokugcina’ owabonisa ukuthi izinto ziyagcina njani (Indeksi Yokugcina Kwemilo), futhi ziyaphuma njani izimoya (Indeksi Yokuphuma Kwemoya). Emva kwalokho, izinto zihlukaniswa emithathu imigqa: Igqa lokuqala uma indeksi yokugcina kwemilo iyisikhombisa 25 noma ngapansi kwalokho, igqa lesibili uma kuyisikhombisa 26–75, futhi igqa lesithathu uma kuyisikhombisa 76–200. Ngaphakathi kwe-EN 13501-1, kubhekwa kakhulu izinkinga eziningi ezifana nokuthi izinto ziyadlula njani (ukuhlukaniswa kusuka ku-A kuya ku-F), ubude bendlela yokuphuma kwemoya okubizwa ngokuthi s1–s3, futhi ukuthi kungasoloko kungabikwa izinkambo zezimilo ezingenayo kahle (d0, d1, noma d2). Ngokuba lezi zinkinga zingabheka kakhulu ukuphuma kwemoya nezinkambo zezimilo ezingenayo kahle, sizibona izimo eziningi kuphela apho izincwadi zezilayili zokufaka ezifanayo ziyahlukaniswa njenge-Igqa lokuqala ngokuzama kwe-ASTM E84 kodwa ziyahlukaniswa njenge-Euroclass C kuphela ngokuzama kwe-EN 13501-1. Lezi zidingo zizingaqondi kakhulu izimpahla zokusebenza kwezwe lonke, futhi ziyabulawa ukuthi zibuye zihlanganise izimpahla zabo zokusebenza ngokuhambisana nomkhakha owabuyela kuyo.

Imigomo Yokuqonda Ukuthi Kuyizwe Ngokukhanya Kwesi-UL 94 Nokuthi Kuyisibonelo Sokusebenza Kwesi-Sheet Seku-Polycarbonate

Izindlela zokusebenza ze-ASTM ne-EN zihlala zihambisana nezinkinga zezincwadi zokubanga, kodwa xa kufikile ekuboneni ukuthi izinto ziyakha njani umoya, lapho kulapho u-UL 94 uyabuka. Lokhu kubona ukuthi izinto ziyakha njani umoya ngokwakhe, okuyisidingo esikhulu ekupheleni kwemisebenzi yokuqinisa umoya kuqonde. Ukuzimisa kubhekisa ukuthi izithombe zizweleka ngokuvuza noma ngokuhorizontali emoyeni, emva kwalokho kubeka iziratingi njenge-V-0, okusho ukuthi umoya uyaphela ngaphansi kwemizuzwana eyishumi, noma V-1/V-2 ozivumela ukuthi umoya uzwele ngemizuzwana ebalulekile, futhi kukho isiratingi se-HB sokuzwelela ngokuhorizontali. Izilayethi zepolycarbonate ezisebenziswa kuzinto njengezibhokisi zezimali, amaphuzu wezithombe zezitreni, nokugcina izinto zokulinda zezinto zokusebenza ziyadinga isiratingi esiphelele se-UL 94 V-0. Ubukhulu bukhona ubuningi obubalulekile kakhulu. Isilayethi esincane seshumi nesibhili (3mm) singathola kuphela isiratingi se-V-2, kodwa ukudlula kusilayethi sesishumi nesikhombisa (6mm) singathola isiratingi esibalulekile se-V-0. Ngakho-ke abengineya bayaqhubeka nokuthatha isibonelo sobukhulu bezinto xa bavakasha izinto ezisebenzisa emazini apho ukuphatha kwezimali kuyisidingo esiphakeme kakhulu.

Ukufikisha Ukuphathiswa: Imithwalo Yokuqonda Euroclass B-s1,d0 Nezinkinga Zokusebenza Kwizibhalo Zokwakha Kwesifundo SaseMelika Kwi-Sheet Zokuphatha Ngamaphetha

Ukuvulula EN 13501-1: Kungani u-B-s1,d0 Yilobuchule Lokuhlanganisa Izindlela Zokusebenza EziyaseYurophu

Isistandare se-EN 13501-1 sibhalisa izinkulungwane zokwakha ngokubhekana nezindilingo ezintathu eziphambili: ukuthi zihlala njani xa ziphakanyiswa ngumoya (kubhaliswe kusuka ku-A ku-F), inombolo yemvumo eshiywa yazo (kubhaliswe ku-s1 kuya ku-s3), nokuthi zishaya izinkqubo zomoya zokuphakama (kubhaliswe ku-d0 kuya ku-d2). Kuma-polycarbonate sheets, isibhalo esiphezulu esinokuthi sisebenze kahle ekhaya kwezindlela zokusebenza ngokwesikhashana siyi-Euroclass B-s1,d0. Lokhu kusho ukuthi umkhawulo kufanele ubonise ukuthi ukuphakama kwamafalame kuncane kakhulu (isibhalo se-Class B), kusha imvumo engaphezu komthwalo wokusha (isibhalo se-s1), futhi akukho zinkqubo zomoya zokuphakama (d0). Isifunda se-EU Construction Products Regulation sibhalisa lokhu kubhalo kwezindawo ezithile njengezindawo zokuphuma kwezimfazwe, izikhulukazi zokuhamba, izindawo zokufunda, izindawo zokuchitha abantu, noma ezinye izindawo apho abantu abaningi baphumelela. I-polycarbonate ichaza kule ndawo ngokwesibonelo kuma-roof panels, ama-room dividers, nama-safety windows.
