Acetal Resin Delin vs. Pom

Deline ke lebitso la khoebo la pom le hlahisitsoeng ke Dupont United States, ke hore, lebelo la tšepe ea tšepe.

Polyfolddehyde (English: Polyformaldehyde) Thermoplanelle Polymer. E tsejoang e le "tšepe ea tšepe" kapa "tšepe ea rune", hape e tsejoang e le PolyoxyMethlene. Ak'u thetsoe ke Pom, ke polymeright e fumanoeng ke polymerization ea folymeldehyde, ka tekanyo e tlase ea polymerication le ho angoa ke polymerization. E ka sebelisoa e le thepa e tala ea indasteri ea lik'hemik'hale ea maiketsetso le sistimi ea maiketsetso, hape e sebelisoa joalo ka lithethefatsi tsa lithethefatsi.

Formaldehyde ke mofuta oa thepa e thata le e bobebe e nang le khanya e ntle le e bobebe kantle, karolo e mosehla kapa e tšoeu e nang le khanya. Mekhoa e sa thellang habonolo ea ho tima, hole le mollo kamora ho latellana, ho na le monko o bobebe oa makhoaba, ho na le monko o mabifi, monko o hlasimollang Polyfolddehyde ke phofo e tšoeu, mebala e tloaelehileng, e nang le matla a shringage 1.41-13, ho omisa shrink.

Ts'ebetso ea nako e telele ea Pom e sa phahame, empa nako e khuts'oane e ka fihlela 160 ℃, eo homone ea pom e sa feleng ho feta 10 ℃, empa copolymeriage ea nako e telele e tiile ea pom ho fapana le homoposization ea pom e phahame ho feta 10 ℃. E ka sebelisoa ho -40 ℃ ~ 100 100 ℃ sekhahla sa mocheso oa nako e telele. Pom e bonolo haholo ho sekaseka, mocheso oa ho sekaseka 280 ℃, ho hlahlojoa ha khase ea ho khoahlafatsang le ho loantšana. Ka hona, tšepe ea hlobo e lokela ho sebelisoa ho hlahisa lisebelisoa tse thibelang khoholeho.

Ts'ebetso ea Mechani

Poho ea Pomma, ho satalla ha maemo, ho hlaka hantle, ho roala botle. Ts'ebetso ea eona ea ho etsa lintho tse ling e ntle haholo, ho feta matla a ho fihla ho 26.5mpa ho feta ts'ebetso ea mocheso e leng pompo ho feta homopolymerization of pom. e kholo hanyane.

Matla a pom a phahame a phahame, empa tšusumetso e tloaelehileng e tlase ho ab le PC;
