Tlaleho ea Patlisiso ea Indasteri ea Polyurethane (Karolo A)

1. Kakaretso ea indasteri ea Polyurethane

Polyurethane (PU) ke thepa ea bohlokoa ea polymer, eo mefuta e mengata ea likopo le mefuta e fapaneng ea lihlahisoa e e etsang karolo ea bohlokoa indastering ea sejoale-joale.Sebopeho se ikhethileng sa polyurethane se e fa thepa e ntle ea 'mele le ea lik'hemik'hale, e etsa hore e sebelisoe haholo libakeng tse kang tsa kaho, likoloi, thepa ea ka tlung le lieta.Nts'etsopele ea indasteri ea polyurethane e susumetsoa ke lintlha tse fapaneng joalo ka tlhoko ea 'maraka, boqapi ba theknoloji, le melaoana ea tikoloho, e bonts'ang ho ikamahanya le maemo ho matla le bokhoni ba nts'etsopele.

2. Kakaretso ea Lihlahisoa tsa Polyurethane

(1) Polyurethane Foam (PU Foam)
Foam ea polyurethaneke e 'ngoe ea lihlahisoa tsa mantlha tsa indasteri ea polyurethane, e ka aroloang ho foam e thata le foam e tenyetsehang ho latela litlhoko tse fapaneng tsa kopo.Foam e thata e sebelisoa hangata libakeng tse joalo ka mabokose a lipalangoang le a batang, athe foam e tenyetsehang e sebelisoa haholo lihlahisoa tse kang materase, lisofa le litulo tsa likoloi.Foam ea polyurethane e bonts'a thepa e ntle joalo ka boima bo bobebe, ho kenya mocheso, ho monya molumo le ho hanyetsa khatello, e bapala karolo ea bohlokoa bophelong ba sejoale-joale.

• PU Foam e thata:Foam e thata ea polyurethane ke thepa ea foam e nang le sebopeho sa lisele tse koetsoeng, tse khetholloang ka botsitso bo botle ba sebopeho le matla a mochini.Hangata e sebelisoa lits'ebetsong tse hlokang matla le boima bo phahameng, joalo ka litšepe tsa moaho, mabokose a lipalangoang a batang le matlo a polokelo a sehatsetsing.Ka sekhahla sa eona se phahameng, foam e thata ea PU e fana ka ts'ebetso e ntle ea ho kenya letsoho le ho hanyetsa khatello, e e etsa sesebelisoa se loketseng bakeng sa ho kenya letsoho le ho paka ketane e batang.
• Flexible PU Foam:Flexible polyurethane foam ke thepa ea foam e nang le sebopeho sa lisele tse bulehileng, tse tsejoang ka bonolo le ho phutholoha.Hangata e sebelisoa ha ho etsoa materase, lisofa le litulo tsa likoloi, e fana ka matšeliso le tšehetso.Flexible PU foam e ka etsoa lihlahisoa tse nang le density e fapaneng le boima ba ho fihlela litlhoko tsa matšeliso le tšehetso ea lihlahisoa tse fapaneng.Bonolo ba eona bo babatsehang le ho tiea ha eona ho etsa hore e be thepa e loketseng ea ho tlatsa thepa ea ka tlung le ka hare ho likoloi.
• PU Foam ea ho itšeha:Foam e entsoeng ka letlalo la polyurethane ke thepa ea foam e etsang lesela la ho itšireletsa holim'a metsi nakong ea ho phophoma.E na le bokaholimo bo boreleli le boima bo phahameng ba holim'a metsi, bo atisang ho sebelisoa lihlahisoa tse hlokang ho boreleli holimo le ho hanyetsa ho apara.Foam ea PU e itšebetsang e sebelisoa haholo ka thepa ea ka tlung, litulo tsa likoloi, lisebelisoa tsa boikoetliso, le likarolo tse ling, e fana ka lihlahisoa tse nang le ponahalo e ntle le nako e telele.

(2) Polyurethane Elastomer (PU Elastomer)
Polyurethane elastomer e na le elasticity e babatsehang le ho hanyetsa ho apara, e atisang ho sebelisoa ha ho etsoa lithaere, litiiso, lisebelisoa tsa ho senya li-vibration, joalo-joalo Ho itšetlehile ka litlhoko, li-elastomer tsa polyurethane li ka etsoa lihlahisoa tse nang le mefuta e sa tšoaneng ea ho thatafala le elasticity ho finyella litlhoko tsa mefuta e sa tšoaneng ea indasteri. le lihlahisoa tsa bareki.

(3)Sekhomaretsi sa Polyurethane (PU Adhesive)

Sekhomaretsi sa polyurethanee na le thepa e babatsehang ea ho tlamahane le ho hanyetsa tikoloho, e sebelisoang haholo ka mapolanka, tlhahiso ea likoloi, sekhomaretsi sa masela, joalo-joalo Sekhomaretsi sa polyurethane se ka phekola ka potlako tlas'a maemo a fapaneng a mocheso le mongobo, ho etsa litlamo tse matla le tse tšoarellang, ho ntlafatsa boleng ba sehlahisoa le tshebetso.

3. Khethollo le Lisebelisoa tsa Polyurethane

ProductsPolyurethane, joalo ka thepa ea polymer e feto-fetohang, e na le ts'ebeliso e fapaneng mafapheng a fapaneng, haholo-holo e arotsoe ka mekhahlelo e latelang:
(1) Lihlahisoa tsa Foam
Lihlahisoa tsa foam haholo-holo li kenyelletsa foam e thata, foam e tenyetsehang, le foam e itšehlang letlalo, ka lits'ebetso tse kenyelletsang:

• Mohaho oa Insulation: Foam e thata e atisa ho sebelisoa ha ho sebelisoa thepa ea ho kenya letsoho mohahong o kang mapolanka a ka ntle a marako le liboto tsa marulelo, ho ntlafatsa ka katleho matla a matla a mehaho.
• Tlhahiso ea Thepa ea Thepa: Foam e tenyetsehang e sebelisoa hangata ha ho etsoa materase, lisofa, litulo, ho fana ka litulo tse mabothobotho le boiphihlelo ba ho robala.Foam ea ho iketsetsa letlalo e sebelisoa bakeng sa mokhabiso oa holim'a thepa ea ka tlung, ho ntlafatsa botle ba sehlahisoa.
• Tlhahiso ea Likoloi: Foam e feto-fetohang e sebelisoa haholo litulong tsa likoloi, ka hare ho mamati, ho fana ka boiphihlelo bo botle ba litulo.Foam ea ho iketsetsa letlalo e sebelisoa bakeng sa liphanele tsa ka hare tsa likoloi, mabili a tsamaisang, ho ntlafatsa botle le boiketlo.

(2) Lihlahisoa tsa Elastomer
Lihlahisoa tsa Elastomer li sebelisoa haholo-holo libakeng tse latelang:

• Tlhahiso ea Likoloi: Li-elastomers tsa polyurethane li sebelisoa haholo tlhahiso ea likoloi, joalo ka lithaere, litsamaiso tse emisitsoeng, litiiso, ho fana ka ts'ebetso e ntle ea ho ts'oara le ho tiisa, ho ntlafatsa botsitso le boiketlo ba koloi.
• Litiiso tsa indasteri: Li-elastomer tsa polyurethane li sebelisoa e le lisebelisoa bakeng sa litiiso tse fapaneng tsa indasteri, joalo ka li-O-rings, li-gaskets tse tiisang, tse nang le khanyetso e ntle ea ho roala le ho hanyetsa kutu, ho netefatsa ts'ebetso ea ho tiisa lisebelisoa.

(3) Lihlahisoa tse khomarelang
Lihlahisoa tse khomarelang li sebelisoa haholo-holo libakeng tse latelang:

• Ho sebetsa ka lehong: Likhomaretsi tsa polyurethane li atisa ho sebelisoa bakeng sa ho kopanya le ho kopanya lisebelisoa tsa lehong, tse nang le matla a matle a ho kopanya le ho thibela metsi, tse sebelisoang haholo ho etsa thepa ea ka tlung, ho sebetsa ka mapolanka, joalo-joalo.
• Ho Etsa Likoloi: Likhomaretsi tsa polyurethane li sebelisetsoa ho kopanya likarolo tse fapaneng tsa tlhahiso ea likoloi, joalo ka liphanele tsa 'mele, litiiso tsa lifensetere, ho netefatsa botsitso le ho tiisoa ha likarolo tsa koloi.
