Elastomers le ts'ebeliso ea bona.

Li-elastomers tsa polyurethane li karolo ea sehlopha sa polasetiki, tse thehiloeng ka lebaka la polymerization, 'me liketane tsa tsona tse kholo li na le lihlopha tsa urethane. E bonts'oa e le PUR kapa PU, li na le thepa e ngata ea bohlokoa. Melemo ea bona le theko e ntle haholo li etsa hore elastomers e be thepa e sebelisoang haholo indastering e mengata.

Sebaka sa Elastomer:
Lisebelisoa tsa PUR ke thepa e joaloka rabara. Ho tloha ka rabara li fapana, har'a tse ling ka hore ba na le litekanyetso tse betere tsa 'mele le tsa lik'hemik'hale ho feta tse nang le tsona. Ntle le moo, ho a khonahala ho bopa thepa ea li-polyurethane elastomers ka bongata bo fapaneng haholo. Ts'ebetsong, sena se bolela hore PU ke thepa ea bokahohleng.

Melemo ea eona e meholo e kenyelletsa index ea ho tlatlapa e phahameng, eo e e fihlelang ka lebaka la ho hanyetsa ha eona haholo:

ketso ea lintho tse nang le lik'hemik'hale tse kang peterole, li-sol soline, oli, mafura, sulfuric asiti, sesebelisoa sa caustic kapa metsi a letsoai; ho feta moo, lihlahisoa tsa PU li ka sebetsa tikolohong eo pH ea eona e pakeng tsa 5 le 12,
mongobo le maemo a mang a leholimo a mabe,
abrasion,
ho otlolla, ho rusolla le ho putlama - lihlahisoa tse entsoeng ka polasetiki ea PUR li khona ho mamella mocheso ho tloha ho -40 ° C ho isa ho 80 ° C,
botsofe.
Ke likarolo life tse ling tseo polyurethane elastomers e ikhethang ka tsona? Ho hlile ho bohlokoa ho bua mona hore ho na le:

ba ikhopolang ho timang
lipoleiti,
bao e seng ho tšoaea,
makhetlo a tšeletseng a bobebe ho feta tšepe.
Ntle le moo, lihlahisoa tse entsoeng ka thepa ea PUR li na le thepa e ntle haholo ea damping mme li ka sebelisoa maemong a metsi le a omileng. Kamora nako, ba khetholloa ke sebaka se boreleli ebile se benya ebile se le thata ka ho felletseng, se sa thibeleng ho boloka elongation ea bohlokoa.

Ts'ebeliso ea polasetiki ea PUR ke eng?
Li-elastomers tsa polyurethane li sebelisoa hangata, har'a tse ling mechini, indasteri ea lik'hemik'hale le tsa masela. Joaloka thepa e kang rabara, e nang le thepa e betere ho feta ea rabara ka boeona, ke thepa e ntle bakeng sa tlhahiso ea lihlahisoa tse kang:

gasket,
lera la,
li-roller,
libaesekele tse ka hare
mabili a makoloi a koloi,
scrapers
lebanta la khanna, likamore tsa khatiso le liluloana tsa mefuta e fapaneng ea mechini ea liindasteri,
li-roller, lipara tse thibelang ho thothomela le lintho tse ling tse fifatsang,
likotsi tsa makoloi a koloi.
Joalokaha u bona, karolo ea polyurethane elastomers indastering e bohlokoa, mme karolo ea ts'ebeliso ea bona e pharaletse haholo.
