Patlisiso mabapi le Khatello ea Khale ea Lisebelisuoa tsa Likoloi le Mekhoa ea Ts'ebeliso ea Lithaele tse Retardant tsa Lelakabe ka har'a Likoloi.
Ka tsoelo-pele e potlakileng ea indasteri ea likoloi, likoloi—tse sebelisoang bakeng sa ho tsamaea kapa ho tsamaisa thepa—li fetohile lisebelisoa tsa bohlokoahali bophelong ba batho. Le hoja likoloi li fana ka boiketlo, li boetse li baka likotsi tsa tšireletso, tse kang likotsi tsa likoloi le ho cha ho iketsahallang feela. Ka lebaka la sebaka se koaletsoeng le thepa ea ka hare e tukang, hang ha mollo o qhoma koloing, hangata ho thata ho laola, ho beha bophelo le thepa ea bapalami kotsing. Ka hona, polokeho ea mollo likoloing e lokela ho ba taba e kholo ho basebelisi.
Lisosa tsa ho cha ha likoloi ka kakaretso li ka aroloa ka:
(1) Lintlha tse amanang le likoloi, ho kopanyelletsa le mathata a motlakase, ho lutla ha mafura, le ho hohlana ha mechine ho bakoang ke liphetoho tse sa lokelang, ho kenngoa kapa tlhokomelo.
(2) Mabaka a ka ntle, a kang ho thulana, li-rollovers, ho chesa, kapa mehloli e sa lebelloang ea mollo.
Likoloi tse ncha tsa motlakase, tse nang le libeteri tse matla a matla a matla, li tloaetse ho chesoa ke mollo ka lebaka la lipotoloho tse khutšoane tse bakoang ke ho thulana, ho phunya, ho baleha ha mocheso ho tsoa mochesong o phahameng, kapa hona joale ho feta tekano nakong ea ho tjhaja kapele.
01 Patlisiso mabapi le Khatello ea Lelakabe la Lisebelisuoa tsa Likoloi
Thuto ea lisebelisoa tse thibelang malakabe e qalile qetellong ea lekholo la bo19 la lilemo United States. Ka tsoelo-pele ea theknoloji lilemong tsa morao tjena, ho bile le litlhoko tse ncha tsa lipatlisiso mabapi le ho lieha ha lelakabe la thepa ea ka hare ea likoloi, haholo-holo libakeng tse latelang:
Taba ea pele, lipatlisiso tsa theory mabapi le ho lieha ha lelakabe. Lilemong tsa morao tjena, bafuputsi ba Chaena ba hatelletse haholo ho ithuta ka mekhoa ea ho tuka ha likhoele le lipolasetiki tse fapa-fapaneng, hammoho le tšebeliso ea lintho tse thibelang malakabe.
Ea bobeli, nts'etsopele ea lisebelisoa tse thibelang lelakabe. Hona joale, ho na le mefuta e mengata ea lisebelisoa tse thibelang lelakabe tse ntseng li ntlafatsoa. Machabeng, lisebelisoa tse kang PPS, fiber ea carbon, le fiber ea khalase li sebelisitsoe ka katleho liindasteri tse fapaneng.
Ea boraro, ho etsa lipatlisiso ka masela a thibelang mollo. Masela a thibelang mollo a bonolo ho hlahisa le ho sebetsa hantle haholo. Le hoja masela a k'hothone a thibelang malakabe a se a ntse a ntlafalitsoe hantle, lipatlisiso mabapi le masela a mang a thibelang malakabe a ntse a lekanyelitsoe Chaena.
Ea bone, melaoana le mekhoa ea tlhahlobo ea lisebelisoa tse thibelang malakabe.
Lisebelisoa tsa ka hare tsa likoloi li ka aroloa ka mekhahlelo e meraro:
- Lisebelisoa tse thehiloeng ho fiber (mohlala, litulo, lik'hapete, mabanta a pholoso) - tse sebelisoang ka ho fetisisa le tse amanang ka ho toba le bapalami.
- Lintho tse entsoeng ka polasetiki.
- Lisebelisoa tse thehiloeng ho rabara.
Lisebelisoa tse thehiloeng ho fiber, tse tukang haholo 'me li le haufi le bapalami, li baka likotsi tse kholo ha ho ka ba le mollo. Ho feta moo, likarolo tse ling tsa koloi, joalo ka libeteri le lienjine, li haufi le thepa ea masela, e leng ho eketsang monyetla oa ho ata ha mollo. Ka hona, ho ithuta ho lieha ha lelakabe la thepa ea ka hare ho koloi ho bohlokoa ho liehisa ho cha le ho fana ka nako e eketsehileng ea ho phonyoha bakeng sa bapalami.
02 Classification of Flame Retardant Fibers
Lisebelisoa tsa masela a indasteri, masela a likoloi a nka karolo e kholo. Koloi e tloaelehileng ea bapalami e na le lisebelisoa tsa ka hare tse ka bang 20-40 kg, tseo boholo ba tsona e leng masela, ho kenyeletsoa likoahelo tsa litulo, li-cushion, mabanta a pholoho le li-headrest. Lisebelisoa tsena li amana haufi-ufi le polokeho ea bakhanni le bapalami, li hloka thepa e thibelang malakabe ho fokotsa ho ata ha lelakabe le ho eketsa nako ea ho phonyoha.
Likhoele tse thibelang molloli hlalosoa e le likhoele tse sa hleng kapa li sa cheseng ka mokhoa o sa fellang ha li kopana le mohloli oa mollo, tse hlahisang malakabe a fokolang le ho itima kapele hang ha mohloli oa mollo o tlosoa. The Limiting Oxygen Index (LOI) e atisa ho sebelisoa ho lekanya ho chesa, ka LOI e ka holimo ho 21% e bontšang ho chesa ho tlaase.
Li-fiber tse thibelang mollo li arotsoe ka mekhahlelo e 'meli:
- Ka tlhaho Flame Retardant Fibers
Likhoele tsena li na le lihlopha tse thibelang malakabe ka har'a liketane tsa tsona tsa polymer, li matlafatsa botsitso ba mocheso, li eketsa mocheso oa ho bola, li hatella tlhahiso ea khase e tukang, le ho khothaletsa tlhahiso ea char. Mehlala e kenyelletsa:
- Likhoele tsa Aramid (mohlala, para-aramid, meta-aramid)
- Likhoele tsa polyimide (mohlala, Kermel, P84)
- Likhoele tsa polyphenylene sulfide (PPS).
- Polybenzimidazole (PBI) likhoele
- Melamine fibers (mohlala, Basofil)
Meta-aramid, polysulfonamide, polyimide, le likhoele tsa PPS li se li entsoe ka bongata Chaena.
- Li-Fibers tse Fetohang tsa Flame Retardant
Likhoele tsena li fumana ho lieha ha lelakabe ka li-additives kapa litlhare tse holim'a metsi, ho kenyelletsa:
- Polyester e thibelang mollo
- Nylon e thibelang mollo
- Viscose e thibelang mollo
- Polypropylene e thibelang mollo
Mekhoa ea ho fetola e kenyelletsa ho kopanya, ho kopanya, ho ohla ka motsoako, ho hlomathiseletsoa le ho qeta ho qeta.
03 Likopo tsa Ts'ebetso e Phahameng ea Li-Fiber tse Retardant Flame ho Tšireletso ea Likoloi
Lisebelisoa tse thibelang lelakabe la likoloi li tlameha ho finyella litlhoko tse khethehileng ka lebaka la mathata a sebaka. Ho fapana le lits'ebetso tse ling, lisebelisoa tsena li lokela ho hanela ho tuka kapa ho bonts'a litefiso tse laoloang tsa ho chesa (mohlala, ≤70 mm/min bakeng sa likoloi tsa baeti).
Ho feta moo, litlhaloso li kenyelletsa:
- Mosi o fokolang haholo le likhase tse chefo tse fokolangho netefatsa polokeho ya bapalami.
- Lintho tse khahlanong le staticho thibela mello e bakoang ke mouwane wa mafura kapa ho bokella lerole.
Lipalo-palo li bontša hore koloi e 'ngoe le e 'ngoe e sebelisa 20-42 m² ea thepa ea masela, e bontšang bokhoni bo boholo ba kholo ea masela a likoloi. Masela ana a arotsoe ka mefuta e sebetsang le e khabisang, e nang le khatiso e ntseng e eketseha ea ts'ebetso-haholo-holo ho lieha ha lelakabe-ka lebaka la ho ameha ka polokeho.
Masela a sebetsang hantle haholo a sa sebetseng malakabe a sebelisoa ho:
- Likoahelo tsa litulo
- Liphanele tsa mamati
- Lithapo tsa thaere
- Airbags
- Likamore tsa marulelo
- Lisebelisoa tsa ho thibela molumo le ho pata
Masela a sa lohiloeng a entsoeng ka polyester, carbon fiber, polypropylene, le fiber ea khalase le tsona li sebelisoa haholo ka hare ho likoloi.
Ho khothaletsa malakabe a ka hare ho likoloi tse sa sebetseng hantle feela ho ntlafatsa polokeho ea bapalami empa hape ho kenya letsoho boiketlong ba sechaba.
