Acetal resin delin vs. Pom

Delin izita rekutengeserana rePOM rakagadzirwa neUPont muUnited States, kureva kuti, mujaho Simbi Pom.

Polyformaldehyde (Chirungu: polyformaldehyde) thermoplastic crystalline polymer. Inozivikanwa se "Super Steel" kana "Race Steel", anozivikanwawo sePolyoxymethyle. Yakapfupikiswa sePom, iri polymer yakawanikwa nePolymerization yeCommenalehdehyde, ine yakaderera yePolymerization uye inokanganiswa kune inopisa depilymerization. Inogona kushandiswa seyakabikwa zvinyorwa zve organic kemikari indasitiri uye synthetic resin, uye zvakare inoshandiswa semishonga inokambaira.

Fomualdehyde rudzi rwezvakaoma uye zvakashata uye zvakajeka kunze, mwenje yero kana chena, yakatetepa-chikamu chakakomberedzwa chakaita semi-glossy. Kuwedzera maitiro ekudzima zviri nyore, kure nemoto mushure mekutevedzana kwekudzima, murazvo wacho webhuruu, paine chinonhuwira chakanyungudutswa Polmfaldehyde ndeye chena poda, yakajairika isiri-yakajeka, gravity yekukara 1.41-1.43 grangeration

Basa renguva refu rekupisa-rekushambadzira harisi rakakwirira, asi pfupi-time rinogona kusvika 160 ℃, umo mafungire emapfupi kupisa kwePom yakakwira kupfuura gumi of pom panzvimbo yehomopolymerization ye pom yakakwirira kupfuura inotevera 10 ℃. Inogona kushandiswa mu -40 ℃ ℃ ~ 100 ℃ Tembiricha chiyero chekushandiswa kwenguva refu. POM iri nyore kuongorora, kuongorora tembiricha ye80 Naizvozvo, chigadziko chesimbi chinofanira kushandiswa kuburitsa zvigadzirwa zvekudzivirira.

Basa rekuita

Simba rePom, kusindimara kwakanyanya, kugona kwakanaka, kwakanaka kupokana. Basa rayo rekuita rakanakisa, pane simba rinosvika 50.5mpa, pane kusindimara kweanosvika ku250mpa. yakakura zvishoma.

POM kukanganisa simba kwakakwirira, asi maitiro akajairwa ari kushoma pane ab abs nePC;

POM inonzwa kuti notch, kunze kweiyo notch inogona kuita iyo gadziriso simba racho richirovera se90%. Simba remafuta rakakunakidza kwazvo, 10 kuchinjanisa mutoro, kupera simba kusimba kusvika ku 35mpa, nepo pa nePC iri chete 28mpa.

Pom Creep uye pa rakafanana, na20 ℃, 21mpa, 3000h chete 2.3%, uye nekudziya idiki kwazvo.

Pom Friction Factor idiki, yakanaka kupfeka kurwisa (pom> PAA6> PATH> HPVC> HPVCER kugadzira ruzha yakafanana nekupopota.

Pom raw zvinyorwa zvekuita maitiro uye mutsauko pakati pemhando dzakasiyana dze pom

Pom Raw Zvinyorwa Synthetic Resin "mune, zvakare anozivikanwa sePolymaCheyde Resin, Simbi, etc.;

1, pom yemukaka chena opaque cryparty theplear resin, neakanaka pese pese pokurarama kwekuwedzera, ine huwandu hwakanyanya hwekuwedzera uye kuomarara, kusimba kwakasimba uye kuomarara kwakananga padyo nesimbi ;.

2, Simba resimba, rinokotama simba, kupokana nekukanda uye kupokana kupokana kwakanaka, kuramba kudzokorora kukanganisa, kupindura kwekutakura kwakanaka.

3.smreen coefficient yekukakavara, kurwisa abrasion, yakanakira kugadzikana, nzvimbo yakanaka, yakakwirira viscoellasity, magetsi akanaka kwazvo, uye haina kukanganiswa nekushisa; Kunaka kwekunzwa kupokana uye hakuna kukanganiswa nekunyorova.

4, Kuwedzera Kemical Kupesana: Kuwedzera kune yakasimba acids, phenols uye organic mersides, yakagadzikana kune mamwe makemikari, kuramba mafuta; Zvivakwa zvemakaniki zvinokanganiswa ne tembiricha idiki, ine yakanyanya kupisa kupisa tembiricha.

5, kukanganisa kwakashata kwakadzoreredza, moto xu Xu Xuxgen Indekisi, kunyangwe kuwedzera kwemamiriro ekunze hakugone kuwana zvinodiwa

6, homopolymer aldehyde yakakwira knot, kuomarara, kupisa tembiricha pane yakaderera, kurwisa kwemakemikari, maitiro anoyerera ari nani pane homopolymer aldehyde, ichangobva kugadzirwa Zvigadzirwa zveiyo Ultra-yakakwira-inoyerera (kukurumidza kurwisa), kukanganisa kuramba uye kuderedza kuumbwa kwemakirini, asiwo inormac filler, mamakisi anovandudzwa.

7, Pom Raw Point Mvura yakakura kupfuura 0.2%, inofanira kunge yakaomeswa usati waumbwa, tembiricha yekudziya yakafanana, inogona kuumbwa, kurova, rotomilding, kurira, kusungwa, kusungwa, Firimu Coating, kudhinda, kuisa mari, kuumba, kuumbwa kwakafanira kugadzirisa 9 kwakakodzera kuti kuve kwakakura .

Musiyano uripo pakati pemhando dzakasiyana dzePom

Pom yakakamurwa kuita copolymalefdehyde uye homopolyformaldehyde.

1, CO-Polyformaldehyde inochinjika kupfuura homopolyformalehdehyde.

2, COPLELOMRFEMACELDEYDE pane homopolyformsehdehyehdehyde kune kupisa kwemvura kupesana neAlkali kuramba kuri nani.

3.

4, parformaaldehyde yakanyanya kuomarara kupfuura copolymaliadehdehdeyde resin, inopera simba uye inodzokororwa kukanganisa uye zvimwe zvekurwisa uye zvimwe zvimiti zvakanakisa.

5, General Giredhi, Copolymaldehyehyde pane homopolyformaldehdehdehdehyde mamiriro ekunze kupokana kuri nani zvishoma.
