Pom PoldaCetal, dzimwe nguva tinoti "Simbi Simbi", dzimwe nguva inoidaidza kuti "trane", saka nei zita rakadai? Nekuti, zita rinowanzove vabereki varo, kureva kuti, muvengi wayo.
Isu tinoziva kuti kune marudzi makuru maviri eParformaldehyde, imwe inonzi Coplyformaldehdehyde, uye imwe yacho inonzi homoponyformcadehdehydehdehdehdehdehdehdehdehy. Kugadzirwa kwecompany yeFopolysehyde kambani (United States Celesse) yakanyorwa zita rekuti "Celcon", Simbi ", United States Dupont) zvakare akanyoreswa A Trademark zita, inonzi "delrin", phonetical yakashandurwa se 'delrin'. Paremendildehyde inzira yemutsara polymer isina ngetani ngetani, yakakwirira density uye yakakwirira crystallinity. Sekureva kwemakemikari akasiyana emakemikari mune comelular cheni, inogona kukamurwa kuva marudzi maviri ehomo- uye co-polyformaldehyde.
Musiyano wakakosha pakati pezviviri zviri: Homopolumerization of formaldehyde density, kuchema, kusimba kweiyo acid uye alkali yakaderera, iyo United States Dupent yakagadzira homopolymerization ye formeldehy ye formaldehy ye formaldehy ye formaldehy ye formaldehy ye formaldehy ye formaldehy ye formaldehy ye formaldehy ye formaldehy . Uye CopollyaCheleyde Density, Crystallinity, Inonyungudika, Simba rakanyanyisa, risingaenzaniswi, kugadzirisa tembiricha yakakura, kusimba kweAcid naAlkali iri nani. Iyo ipurasitiki yemapurasitiki ine yakanaka yakazara yakazara kuita. Iyo ine yakanaka yemuviri, michina uye yemakemikari zvivakwa, kunyanya kupokana kwakanaka.
Inowanzo zivikanwa sejaho resel, yechitatu yakakura general engineering mapurasitiki. Inokodzera kugadzirwa kwekupfeka zvikamu, kutamisa zvikamu, uye indasitiri yemakemikari, chishandiso uye zvimwe zvikamu. United States Celesse yakagadzira iyo Copolymerization yeFomuldehyde.
Pom Injiniya Injini Purastics Hunhu:
1, POM inogona kushandiswa pasina kuoma usati wagadziriswa, zvakanakira preheat panguva yekugadzirisa (anenge 80 ℃), kugadzikana kwechigadzirwa chechigadzirwa chakanaka;

3, POM hazvisi nyore kutora mwero, mvura yekunyora ye1,25 kukanganisa kwekutonhora kwe 172 ℃.
POM PLUPIC SECHICIALS Properties: Simba rePOM, kusindimara kwakanyanya, kugona kwakanaka, kwakanaka kupfeka kuramba. Zvivakwa zvayo zvinokatyamadza zvakanaka, kupfuura simba racho rinogona kusvika 50.5mpa, pane kusindimara kweanosvika pamakesi ePom nekushambadzira kwechidimbu ichi, copolymerization ye pom pane homopolymerization ye pom, Shanduko yacho yakakura zvishoma.Pom kukanganisa simba rakakwira, asi maitiro akajairwa haana kushoma pane abu nePC; Pom notch-inonzwa, pane nonches inogona kuitwa kune iyo yekukanganisa simba rakadzikira ne 90% yehuwandu. Simba remafuta rakakundikana kwazvo, kupera simba simba kusvika ku35mpa, nepo Pa uye PC iri chete 28mpa. Pom's Creep yakafanana ne pa, na20 ℃, 21mpa, 3000h ingori chete 2.3%, uye nekudziya idiki kwazvo. Chinhu chemhosva chePOM idiki, kupfeka kurwisa kwakanaka, muganho wePV kukosha kwakakura kwazvo, kuzvishingisa. Zvigadzirwa zvePom zvinopesana nekukuya, yakakwira mutoro zviri nyore kuburitsa zvakafanana nemheremhere yekupururudza.
Pom Plastiki Magetsi Zvivakwa:
Pom yeMagetsi insulation yakanaka, ingangoita tembiricha nekunyorova; dielectric nguva dzose uye dielectric kurasikirwa kwakasiyana-siyana kwekushisa tembiricha, humidity uye mafambiro e frequency idiki kwazvo; Akanakisa arc kurwisa, uye anogona kuchengetwa pamhepo dzakakwirira.Pom's Dilelectric Simba rakarondedzerwa nehukobvu, iyo ye1.127mm is 82.7kv / tsicks ye188mm is 23.6kv / mm. Pom Plasttics Yenzvimbo yekuita: POM haina kupokana nekusimba Alkalis alkalis uye oxidizing vamiriri, uye ine yakasimba kune yakanaka solk. etc., uye inogona kuchengetedza yakafungisisa makemikari kugadzikana pakukwirira kwakanyanya. Diki mvura yekunyudza, yakanaka dimensional kugadzikana. Pom's Weather Rishance haina kunaka, refu-term multraviolet, mechanical zvivakwa kudzikira, pamusoro pechikamu uye kupaza. Pom Plastiki Kuumbwa: Crystalline zvinhu, yakatetepa yekunyungudika, kunyungudika uye kusimbisa kwekukurumidza, tembiricha yekudziya iri pasi pekudziya kwekunyungudika kunoitika crystallization. Fluidity iri pakati. Kunyorova kunyorera idiki, haigone kuomeswa.
Modified Pom:
