Karolo ea Li-Catalyst tsa Polyurethane Indastering ea Likoloi

Selelekela

Indastering ea likoloi ea kajeno,polyurethane (PU) thepa e bapala karolo ea bohlokoa ho fihlelleng moralo o bobebe, ho ntlafatsa boiketlo le ho ntlafatsa ho tšoarella. Ho tloha litulong tsa likoloi le li-dashboard ho ea ho li-header le litsamaiso tsa ho thibela molumo, likarolo tsa polyurethane li fumanoa hoo e batlang e le sekhutlong se seng le se seng sa koloi. Ka mor'a ts'ebetso e phahameng ea thepa ena ho na le mokhanni oa bohlokoa oa lik'hemik'hale.—epoliethane sethothetsi. Sesebediswa sa polyurethane se laola sekhahla sa karabelo pakeng tsa di-isocyanate le di-polyol, ka hona se netefatsa hore tshebediso e nngwe le e nngwe ya dikoloi e fihlella thepa e hlokahalang ya mechini le ya mmele.

Ke EngLi-Catalyst tsa Polyurethane?

Li-catalyst tsa polyurethane ke dikhemikhale tse potlakisang karabelo pakeng tsa di-polyol le di-isocyanate nakong ya ho thehwa ha foam. Ntle le di-catalyst, sekgahla sa karabelo ya polyurethane se ne se tla ba butle haholo kapa se sa laolehe bakeng sa tlhahiso ya diindasteri. Ka ho fetola mofuta le bongata ba di-catalyst, bahlahisi ba ka laola ka nepoho ruruha ha gel, ho foamisale ho folisa mekhoa ea ho fumana foam e nang le bothata bo itseng, ho tenyetseha le botsitso.

Mefuta e 'meli e meholo ea li-catalyst tsa polyurethane tse sebelisoang indastering ea likoloi ke:

Li-catalyst tsa amine—e sebediswa haholoholo ho kgothaletsa karabelo ea phumulo (karabelo ea isocyanate ea metsi) le ho leka-lekanya mothapo oa ho phahama ha foam le sebopeho sa sele. Mohlala, li-catalyst tsa amine tse tharo tse kang MXC-A1 (BDMAEE) le MXC-37 li fella ka ho phahama ha foam ka mokhoa o boreleli le kabo ea sele e tšoanang.

Li-catalyst tsa tšepe—dikhataholetsi tse thehilweng ka thini, tse kangdibutyltin dilaurate (MXC-T12) leoctoate ea stannous, potlakisakarabelo ea gel (karabelo ea polyol-isocyanate), ka hona e potlakisa ho fola le ho ntlafatsa matla a mechini. Litsamaisong tsa tikoloho, tse nchali-catalyst tsa tšepe tse se nang thini li ntse li sebelisoa ka ho eketsehileng ho fokotsa mesi e tsoang le chefo.

Litšebeliso tsa Bohlokoa tsa Likoloi tsa Li-Catalyst tsa Polyurethane

1. Litulo tsa Likoloi le Li-headrest

Foam e tenyetsehang ea polyurethane ke thepa ea ho boloka mosamo e sebelisoang haholo litulong tsa likoloi le litulong tsa hlooho.MXC-A33or MXC-BDMA thusa ho laola ho teteana le ho mamella ha foam, ho netefatsa boiketlo le ho tšoarella ho tsitsitseng. Sistimi e leka-lekaneng ea catalyst e fana ka botle bo botleho phalla ha sele kapele, sebopeho se tšoanang sa sele,le ho hlaphoheloa hantle ha khatello thepa, e sebelisetsoang ho hlahisa litulo tsa likoloi tse sebetsang hantle.

2. Li-dashboard le Mabili a Setereng

Hangata lifomo tsa polyurethane tse thata le tse nang le masoba a manyenyane li sebelisoa li-dashboard le mabiling a setering. Lisebelisoa tsena li tlameha ho kopanya ho tenyetseha le botsitso ba litekanyo. Li-catalyst tse kangMXC-R70 leMXC-B20 li sebelisoa ho laola tieho ea ho teteana ha karolo e ka pele ha ka nako e ts'oanang li netefatsa hore karolo e ka morao e phekoleha hantle. Sena se fella kabokaholimo ba foam bo borelelile ho khomarela ho babatsehang ho ea ho substrate, ho ntlafatsa botle le maikutlo a ho ama.

3. Taolo ea NVH (Lerata, Ho thothomela, le Bohloko)

Foam ea polyurethane ke thepa e sebetsang hantle haholo e monyang molumo le e thothometsang, e sebelisoang haholo liphanele tsa mamati, li-headliner le ho kenya mocheso fatše.MXC-41le MXC-TMA netefatsa ho bopa foam ka nepo le sebopeho se tsitsitseng sa sele, ka hona ho ntlafatsa ts'ebetso ea molumo le ho thibela mocheso.

4. Liaparo le Likhomaretsi tsa Likoloi

Tšimong ea ho roala le ho khomaretsa likoloi, li-catalyst tsa polyurethane tse kangMXC-T9le MXC-T12 ho potlakisa dikarabelo tsa ho kopanya le ho fola, ka hona ho ntlafatsa ho kgomarela, ho benya le ho hanyetsa dikhemikhale. Dikarolelano tse nepahetseng tsa di-catalyst di netefatsa ho oma kapele ha dikobo le matla a ho kopanya a dikhomaretsi maemong a fapaneng a mocheso.

Melao-motheo ea Ts'ebetso ea Li-Catalyst tsa Polyurethane Tlhahisong ea Likoloi

Ho thehoa ha polyurethane ho kenyelletsa liketso tse peli tsa mantlha tsa lik'hemik'hale:

Karabelo ea Gelling:Pakeng tsa isocyanate le polyol, ho theha maqhama a urethane le ho fana ka matla.

Karabelo e Fokang:Pakeng tsa isocyanate le metsi, ho hlahisa carbon dioxide ho hlahisa foam.

A sistimi e leka-lekaneng ea ho kenya tšebetsonge etsa bonnete ba hore dikarabelo tsena tse pedi di etsahala ka lebelo le laolwang. Di-catalyst tsa amine di kgothaletsa karabelo ya ho foka, ha di-catalyst tsa tshepe di potlakisa ho ntsha ha metsi. Motswako o nepahetseng o dumella foam ho hola hantle ntle le ho putlama, ha e ntse e fola ka ho lekaneng ho fihlella tshebetso e phahameng ya mechini.

Tlhahisong ea likoloi, liparamente tsa ts'ebetso tse kangmocheso, mongobo le karolelano ea ho kopanyali behiloe leihlo haufi-ufi ho ntlafatsa katleho ea li-catalyst. Sepheo ke ho fihlela litšobotsi tse tsitsitseng tsa foam, mesi e fokolang, le botsitso ba ts'ebetso ea nako e telele.

Melemo ea ho Sebelisa Li-Catalyst tsa Polyurethane tse Sebetsang ka Botlalo

Taolo e Nepahetseng:Fetola nako ea ho foa le ho qhibilihisa bakeng sa likarolo tse fapaneng tsa likoloi.

Monko o Tlase le ho Ntša Mosi:Li-catalyst tsa sejoale-joale tse kangMXC-R40leMXC-70e fana ka ts'ebetso e tlase ea VOC e loketseng kahare ho likoloi tse amohelang tikoloho.

Ho lumellana:E sebetsa ho tsona ka bobeliHFCleSistimi ea moemeli oa ho foka oa HFO, ho tšehetsa mekhoa ea tlhahiso e tsitsitseng.

Ho Sebetsa ho Ntlafetseng:Ntlafatsa ho mamella foam, ho khomarela, le ho hanyetsa mocheso bakeng sa nako e telele ea bophelo ba karolo.

Qetello

Li-catalyst tsa polyurethane ke bahale ba sa rorisoang ba tšehetsang boiketlo, polokeho le ho tšoarella ha likoloi tsa sejoale-joale. Ka ho laola sekhahla sa karabelo le sebopeho sa foam, li netefatsa hore setulo se seng le se seng, phanele le lera la ho kenya mocheso li fihlela maemo a thata a likoloi. Ha indasteri e ntse e fetohela homoralo o bobebele tlhahiso e tala, dikhatalyst tsa polyurethane tse sebetsang hantle haholo, tse nang le mosi o fokolang di tla tswela pele ho bapala karolo ho kganneng boqapi.
