Pomb yepurasitiki

PolyoxyMethylene (Polyformaldehyde) (Saigang ~ kutyisa)

Chirungu Zita: PolyoxyMethylene (Polyformaldehyde)

Pom (Polyformaldehyde Resin) Tsanangudzo: Polyformaldehyde itsime renhengo Polymer pasina maketani, akanyanya kuwanda uye akakwirira crystallinity. Sekureva kwemakemikari akasiyana emakemikari mune yayo molecular cheni, inogona kukamurwa kuva marudzi maviri ehomo- uye co-polyformaldehyde. Musiyano wakakosha pakati pezviviri ndewekuti: Hobopolization of formaldehyde density, crystallinity, yekunyungudika yakakwira, Uye Copelmerization yeForplehdehyde Density, Crystallinity, Simba rakadzika, asi iri nyore kugadzirira, inenge 50 ℃), kusimba kweAcids uye zvigadziko zviri nani. Iyo ipurasitiki yemapurasitiki ine yakanaka yakazara yakazara kuita. Iyo ine yakanaka yemuviri, michina uye yemakemikari zvivakwa, kunyanya kupokana kwakanaka. Inowanzozivikanwa sesimbi kana simbi, yechitatu yakakura-yekare-general-chinangwa mapurasitiki. Izvo zvakakodzera kugadzirwa kwekupfeka-kudzikisa uye kupfeka zvikamu, kutapurirana zvikamu, pamwe nendarama yemakemikari, chishandiso uye zvimwe zvikamu.

General Properties

Paremendildehyde rudzi rwezvakaoma uye zvakashata uye zvakajeka uye zvakasviba, zvakachena yero kana chena, uye chikamu chakavhurika, uye chikamu chakakomberedzwa chevhu. Hunhu hwekubatanidza zviri nyore kupisa, ramba uchipisa mushure mekusiya moto, murazvo wacho uri kumusoro kwebhuruu, iko kuguma kwemadonhwe akanyungudutswa, pane kunhuhwirira kwakasimba Polyformaldehyde ndeye chena poda, kazhinji opaque, gravoring yakanaka, magirazi e -40, kuumbwa, mamiriro ekunyima Pom's Long Rish Kudzikiswa haina kukwirira, asi ipfupi inosvika 160 ° comer -ther yePom Pom Pom-Resmermerization yePom yakakwira kupfuura iyo 10 ° Coms Izwi rekupisa-rinodzivirira Coplymer Pom pane pane iyo yakareba-yekupisa kupisa-kupesana pom. Kupisa-kupokana neCopolymerization POM panzvimbo pane Homopolymerization POM anenge 10 ℃ kumusoro. Inogona kushandiswa kwenguva yakareba mune tembiricha ye-tembiricha ye -40 ° C kusvika 100 ° C. Pom iri nyore kwazvo yekuzvidza, tembiriti yemadhirabhu makumi maviri nemana. Kuora kwekutsamwisa uye kupokana gasi kunoitika. Naizvozvo, simbi yechiumbwa inofanira kusarudzwa kugadzirwa kwekushora-kupesana nekudyidzana.

Michina yezvivakwa

Simba rePom, kusindimara kwakanyanya, kugona kwakanaka, kwakanaka kupokana. Zvivakwa zvayo zvinokatyamadza zvakanaka, pane simba rekusvika 50.5mpa, pane kusindimara kwesimba rekuchinja kwesimbi idiki. isimba rakakura zvishoma.Poman kukanganisa kwakakwirira, asi nguva dzose kukanganisa kuri kushoma pane iyo abs nePC; Pom notch-inonzwa, pane nonches inogona kuitwa kune iyo yekukanganisa simba kudonha zvakanyanya se 90%. Simba remafuta rakakundikana kwazvo, 10 kuchinjanisa mutoro, kupera simba simba kusvika ku35mpa, nepo pa nePC iri chete 28mpa. Pom's Creep yakafanana neiyo ye pa, na20 ℃, 21mpa, 3000h ingori chete 2.3%, uye nekudziya idiki kwazvo. Pom's Friction Compoltion idiki, yakanaka abrasion kupokana (pom> PA6> PA6> HPVC> POM> HPVC> PC> PC) kupokana Zvakanaka (pom> PA6> PS> PC). Pom ine chidiki chidiki chekukakavara, chakanakira kupokana (pom> PA6> PATH> HPVCom> PC), Kana mitoro yakakwirira ikashandiswa.

Zvivakwa zvemagetsi

Pom yeMagetsi insulation yakanaka, ingangoita tembiricha nekunyorova; dielectric nguva dzose uye dielectric kurasikirwa kwakasiyana-siyana kwekushisa tembiricha, humidity uye mafambiro e frequency idiki kwazvo; Arc kuramba kwakanaka, uye kunogona kuchengetedzwa kupisa kwakanyanya.Pom's Dilelectric Simba Rakaenderana nehukobvu hwehuwandu hwe1.127mm is 82.7kv / tsicks of 1.88mm is 23.6kv / mm.

Zvemamiriro ekunze

Pom haina kuramba kusimba alkalis alkalis uye oxideizers, uye ine imwe kugadzikana kuEnoc acid uye ALDEHOLS. pakupisa kukuru. Diki mvura yekunyudza, yakanaka dimensional kugadzikana.

Pom's Weather Resistance haina kunaka, yakareba-refu-pasi pechiitiko che Ultraviolet mwenje, mechaniki zvivakwa kudzikira, pamusoro pechikamu uye kupaza.

Kuumbwa

Crystalline zvinhu, inonyungudika yakamanikana, inonyungudika uye yekunyungudika uye kusimbisa kukurumidza, tembiricha yekudziya zvishoma pazasi pekunyungudika tembiricha inoitika. Kuyerera kuri pakati. Kunyorova kunyorera idiki, haigone kuomeswa.

Yakagadziriswa Pom

Yakavandudzwa Pom

Iyo huru yekusimbisa midziyo yegirazi, girazi mabhora kana carbon fills, nezvimwe, mushure mekuwedzera kwezvinhu zvinowanzowedzerwa ne2 kusvika ku3, kupisa kupisa kwakashata kwakawedzera neanopfuura 50 ℃ .

Peel yakakwira lubrication pom

Wedzera girazi, F4, Molybdenum Disulfide, Lubricants uye Low Molecular Kurema Pe muPom kunogona kugadzirisa zvivakwa zvayo. Semuenzaniso, kuwedzera zvikamu zvishanu zveF4 muPOM kunogona kuderedza iyo friction factor ne60%, uye kugadzirisa kupfeka kupokana ne1 kusvika ku2 nguva. Mumwe muenzaniso, unowedzera mvura lubricant kuenda kuPom inogona kuvandudza kwazvo kupfeka kupokana uye kwekupedzisira PV kukosha kwePV. Kuti uvandudze kupararira kwemafuta nemafuta, kuda kuwedzera kabhoni dema, Aluminium Hydroxide Barium Bari Ulfate, ethylene Progyone Rubber uye mamwe mafuta ekutakura. Wedzera 5% Oiri Pom Friction yakawedzera ne72%, iyo yekupedzisira PV kukosha kwe4,9mpa-m / s (yakachena pomb-m / svini yeinjiniya katatu kusvika ku20 nguva.

Kushandiswa kwePolyformaldehyde

Polmfaldehyde ine simba rakanakisa, simba chairo uye kunyudzwa kwakananga uye simbi zviri pedyo zvakanyanya, saka inogona kutsiva simbi isiri-yakasiyana siyana kuita zvikamu zvakasiyana siyana. Izvo zvakanyatsokodzera kugadzirwa kwekugadzira-kupokana, zvinopesana nevaridzi uye nemagirafu, mapepa, etecisiona , zvishandiso zvekuvaka, etcc. mumotokari indasitiri yemotokari, inogona kushandiswa kuburitsa zvikamu zvakasiyana siyana zvemamiriro ezvinhu.

Mune indasitiri yemotokari, zvakanakira simba rayo rakakwirira kwazvo ratanga kutsiva zinc, mhangura uye madzishe emvura, ganda remvura, ma gasi, mafuru, akasanganiswa masaini, Kubata Knuckle Bearings uye zvichingodaro.

Mundori yemichina, nekuda kweiyo polyformaldehyde kupera simba, simba rakakura uye humwe humwe, zviumbwa, miviri yemapomba, mahedhari, macves, mapururu uye zvakadaro on.

Mumagetsi, magetsi, indasitiri, nekuda kweiyo polyformaldehyde dielectric, etces , zvinyorwa zvevhidhiyo, etc. accessories.

Mukuwedzera, inogona zvakare kushandiswa mumidziyo yekuvaka, yakadai seinofa, matangi emvura, gasi met metsi uye mvura pombi majoini, etc.; Inoshandiswa mumishini yekurima, sekubatana uye kubatana kwezvikamu zveMbeu Kuisa Machine, Irrigation Pump Shells, Sprayer Nozzles, etc.; Nekuda kweiyo isina-chepfu, isina maine, asi yakashandiswawo muindasitiri yechikafu, yakadai seyakagadziriswa michina yezvikamu zviri pazvikamu, maGears, fani, zvigaro.
