PU litiiso

Lesale la ho tiisa la polyurethane le khetholloa ka ho hanyetsa ho apara, oli, acid le alkali, ozone, botsofali, mocheso o tlaase, ho taboha, tšusumetso, joalo-joalo lesale la ho tiisa la polyurethane le na le moroalo o moholo oa ho tšehetsa matla 'me o sebelisoa haholo libakeng tse sa tšoaneng. Ntle le moo, selikalikoe sa ho koala sekheo se hanana le oli, ha se na hydrolysis, ha se sebetse, 'me se na le matla a phahameng, se loketseng lisebelisoa tsa oli tse phahameng, lisebelisoa tsa ho phahamisa, lisebelisoa tsa mochini oa forging, lisebelisoa tse kholo tsa hydraulic, jj.

Polyurethane seal ring: polyurethane e na le thepa e ntle haholo ea mochini, 'me ho hanyetsa ha eona ho apara le ho hanyetsa khatello e phahameng ho phahametse liraba tse ling. Ho hanyetsa botsofali, ho hanyetsa ozone le ho hanyetsa oli le tsona li ntle haholo, empa ho bonolo ho hydrolyze ka mocheso o phahameng. Ka kakaretso e sebelisoa bakeng sa likhokahano tsa tiiso tse hanyetsanang le khatello e phahameng le tse sa senyeheng, joalo ka li-cylinders tsa hydraulic. Ka kakaretso, mocheso o fapaneng ke - 45 ~ 90 ℃.

Ntle le ho fihlela litlhoko tse akaretsang tsa lisebelisoa tsa ho tiisa lesale, mehele ea tiiso ea polyurethane le eona e tla ela hloko maemo a latelang:

(1) E tletse ka elasticity le ho tiea;

(2) Matla a loketseng a mochini, ho kenyelletsa matla a ho atolosa, bolelele le ho hanyetsa meokho.

(3) Ts'ebetso e tsitsitseng, ho thata ho ruruha bohareng, le phello e nyenyane ea mocheso oa mocheso (Joule effect).

(4) E bonolo ho e sebetsa le ho bōptjoa, 'me e ka boloka boholo bo nepahetseng.

(5) Ha e senye sebaka sa ho kopana 'me e silafatsa mokhoa oo.

Ningbo Yokey Automotive Parts Co., Ltd e tsepamisitse maikutlo ho rarolleng mathata a thepa ea rabara ea bareki le ho rala mekhoa e fapaneng ea thepa e ipapisitseng le maemo a fapaneng a ts'ebeliso.
