Kunyangwe paine misiyano iri mumhando mbiri dzemhando dzeCCFaldehyde, asi chikamu cheCC zvisungo zveCoplyformalehdehdehdehdehs ( , vane hunhu hwakafanana.

Properties data yePolyoxymymylene (Pom)

2. Mechanics Properties

Paremerialdehyde inzvimbo yeCrystalline Yemanyoro, nekukwira kwakanyanya uye kuomarara kwakanyanya, kunogona kudzikamisa kukanganisa kwakanyanya, uye kukosha kwesimba nekukanganiswa kwekuchinja kwekudzidzira zvidiki, zvinogona kuve Mu -40 ~ 100 ℃ Kuti uwane kushandiswa kwenguva refu.

Iyo crystallinity yeparakemaldehyde inopfuura 70%, saka ine yakanakisa kuramba. Ndiwo mukuru anonyanya kupera simba pakati pezvivakwa zveTermoplastic, uye akakodzera zvakanyanya kune zvigadzirwa zvegiya pasi pekudzokororwa kwemauto ekunze uye zvikamu pasi pekugara tichidaro.

Kudzikisira kwekutya kwePolymaldehyde kwakafanana neiyo yePolyamide uye mamwe mapurasitimu emapuranga, uye kukosha kwayo kwekushomeka kwekushisa, kunyangwe kupisa kwakanyanya, kupokana kwekutya kuchiri kwakanaka. At 23 ℃, 21mpa mutoro, mushure me3000h Creep kukosha ndeye chete 2.3%.

Simba rekubatanidza rePolyformaldehyde rakakura, uye simba rekubatanidza remamoleky, saka kupokana kwekupokana kwakanaka. Chinhu chekupfekedzwa uye kupfeka huwandu hwePolymaldehdehdehdehdehdehyde zvidiki, uye muganho PV kukosha kwakakura, saka kwakakodzera kuti utsinye hwekutsvedza-pfupi. Uye zvivakwa zvekuzvifunga ndezvekuti zvivakwa zvisina mafuta

3. Thermal Properties

Polyformaldehyde has a high heat distortion temperature of 124°C for homopolyformaldehyde and 110°C for copolyformaldehyde. Iko kupisa kupisa tembiricha yeparakemalehdehyde yakakwira kupfuura iyo yeCoplyformaldehdehdehdehyde, asi iyo yekudzikisira yeParomalehdehyde yakaderera pane iyo yeCoplyformadehdehydehdehdehydehdehyde. Kazhinji, nguva refu yekushandisa tembiricha yeparakeryehdehdehde inenge 100 ℃. Iyo huru yekudyara yedhisheni data yePolyformaldehyde inoratidzwa muTafura 1-1. Polyformaldehyde ichabereka imwe nhanho yekunyorova uye kupisa kuchembera mumvura inopisa, uye hupenyu hwaro hwebasa mumvura inopisa yakadzika kupfuura mumhepo inopisa.

4. Zvivakwa zvemagetsi

Acetal ine zvimiro zvakanaka zvemagetsi, kuparadzwa kwemagetsi idiki, kupaza kuparadzirwa hakuna kuderera, uye kuwanda kwe102 ~ 105Hz uye 20 ~ 100 ℃ tembiricha Range, iyo dielectric inogara ichidaro ye acetaldehyde inochengetwa pane iyo nhanho ye3,1 ~ 3.9. Iyo Difelectr Kurasikirwa Angle Tangenent ine mamiriro akafanana: Kana iyo mvura yekubvisa mwero inowedzera kubva ku0.2% kusvika 0.8%, yayo dielectric kurasikirwa kukosha kwe0, 0.003. Iwo magetsi emagetsi eparakemaldehyde anoratidzwa muTafura 1-1.Hemoyo yakakwirira magetsi emagetsi emagetsi eParformaldehyde haana kunyatsonaka. Sezvo tembiricha inowedzera, iyo dielectric inogara ichitenderera uye dielectric kurasikirwa kona tangent inowedzera zvakanyanya. Naizvozvo, mune yakakwirira-frequency Ortronicry indasitiri, kunyanya iyo Ultra-yakakwira-frequents viisitiri indasitiri inofanirwa kucherechedzwa kana uchishandisa.

Iyo yekuparara voltage ye parfafordehyde yakakwirira, uye kupokana kwayo kune arc kubhururuka kwakanyanya. Kune iyo yakaoma arc neguruva uye fog bvunzo, haiburitse miti yekubvarura uye carbonization. 5.

5. Kemical Resistance

Kudzikiswa kwemakemikari kweParformaldehyde resin inoratidzwa muTafura 1-2. Iyo yekutanga chimiro cheparakemaldehyde inosarudza kuti haina nzvimbo tembiricha tembiricha. Pazasi kana padhuze nenzvimbo yekunyungudika, zvinenge zvisingaite kuwana chero solvent, uye zvinhu zvoga zvoga senge perfluoroacetone kunogona kuumba mhinduro yeDilute. Naizvozvo, mumapurasitiki ese engine muPolyformaldehyde kuramba kune organic sols uye kusagadzikana kwemafuta kwakanyanya. Kunyanya mumamiriro ezvinhu epamusoro ekushisa ane misodzi yakanaka kwazvo kupesana, uye saizi uye simba rekuchinja kwekuchinja hakuna kukura.

Iyo Polyformaldehyde Resin ine yakanaka kuramba kuAliute Acids, asi kune yakasimba Acids, hydrochlor acid, nitruus acid, nitrous acid, etc., kushushikana kwekunetseka kuchaitika.

Nekuda kwekusimbisa kwekupedzisira kuguma Homomagetehdeyde ichave hydrolyzed Kazhinji, zvakachengeteka kushandisa homopolyformalehdehyde chete muAlkali Solution nePP kukosha pazasi pegumi.

Kugona kwekunyorera kweinjiniya ekunakidzwa kwemvura kunogona kazhinji kutungamira kune zvigadzirwa zvekuchinja mune zvigadzirwa, nepo shanduko yedanho racho rakagadzirwa nemvura muParemalehdehded zvakanyanya uye usingaise dambudziko rekushandisa zvinoshanda.

6. Kushandiswa kwePolyoxymymylene (POM)

Mune indasitiri yemichina, paremaldehyde inoshandiswa zvakanyanya mukugadzirwa kwemagiya, maGeli, matsime, etema, eterings, mafura. Inoshandiswa seyakajairika-chinangwa simba kutumira mashandiro emidziyo yezvivakwa zvikamu. Yakagadziridzwa Paremaldehyde inoshandiswa muWashington neyekutsvaira uye nekupfeka simbi idiki, kudzora huwandu hwesimba rezvikamu, uye saka zvinogona kuve dzimwe nzira dzakasiyana siyana dzekuti Copper, zinc uye mamwe masimbi ekugadzira fani, magiya, tie rods uye zvichingodaro. Yakagadziridzwa Polmfaldehdehdehdehdehdehs Chakanyanya, yakanyanya kujairika, yakakwana kugadzirwa kweMotokari, magetsi, zvigaro zveWindow Belt Buckles uye zvichingodaro. Mune zvemagetsi zvemagetsi, parfefaldehyde inoshandiswa mukugadzirwa kwezvikamu zvakasiyana-siyana zvekushandisa zvemagetsi, senge magetsi wrench shell, switching kubata, nezvimwe, pamwe nemidziyo yemumba muzvikamu; Mundima yekuvaka kuti ugadzire kwemawindows mapuranga, washabasins, matangi emvura, magonhi nemahwindo, purleys uye zvichingodaro.
