Izingxenye zemihlangano yepulasitiki Pomol delrin

I-Hony® polyoxymethylene iyipulasitiki enobunjiniyela ye-thermoplastic enokusebenza okuhle kakhulu okuthuthukile ngemuva kwe-nylon. Ukusebenza kwayo akuphansi kwe-nylon, kepha intengo yayo iphansi kune-nylon. I-Polyacetal Resin i-powder emhlophe, ngemuva kokugaya, kuphuzi okuphuzi noma okumhlophe, okuguquguqukayo futhi okucwebezelayo futhi okucwebezelayo okunzima. I-PolyoxyMethylene inezakhiwo eziphakeme nezicindezelayo kanye nokuphikiswa ukukhathala okuvelele, futhi kufanelekile ikakhulukazi ngezinto zokwakha amagiya eziphinde zibhekele amabutho angaphandle isikhathi eside. I-PolyoxyMethylene inobukhulu obuzinzile, ukumuncwa kwamanzi okuphansi, kanye nokuncishiswa okuhle kakhulu kwezingxabano kanye nokuvimbela ukumelana. Ukusebenza; ingamelana ne-tersoion, inokuqina okuvelele, ingasetshenziswa ukwenza imikhiqizo yasentwasahlobo yepulasitiki; Ngokuvamile insoluble ku-solvents ye-organic emazingeni okushisa asekamelweni, angamelana nama-aldehydes, ama-esterd, ama-ether, ama-hykrocarbons nama-alkali abuthakathaka, abuthakathaka kanye nokusebenza kwamafutha okusebenza kahle, kepha hhayi ukumelana ne-acid eqinile; inezakhiwo ezinhle zokufakwa kukagesi. Okubi kwePoloxyMethylene, ukuthi inesilinganiso esikhulu sokubumba kanye nokuqina okungekho emthethweni emazingeni okushisa okubumba.

Ukusebenza okujwayelekile

I-PolyoxyMethylene iyinto enzima futhi ebumnyeyo enomphumela obushelelezi, ocwebezelayo, ophuzi okhanyayo noma omhlophe, futhi ingxenye ethambile yodonga iTranslucent. Izici ezivuthayo kulula ukuzishisa, futhi uqhubeke nokushisa ngemuva kokushiya umlilo. Ukuphela okuphezulu kwelangabi kuphuzi, futhi ukuphela okuphansi kuluhlaza okwesibhakabhaka. Ukuncibilika nokucoca kwenzeka, futhi kunephunga eliqinile le-formaldehydehyde iphunga nephunga le-fishy. I-PolyoxyMethylene yi-powder emhlophe, ngokuvamile i-opaque, ukumibalala okuhle, amandla adonsela phansi athile 1.41-1.43 g / cm3, amazinga okushisa angu-170-200, amazinga okubuyisela ama-170-90 ℃ kumahora ama-2. Ukumelana nokushisa kwesikhashana kwe-pom akuphezulu, kepha kungafinyelela ku-160 ° C ngesikhathi esifushane. Ukuvikelwa kokushisa kwesikhashana kwesikhashana kwe-homopolymerized pom kungaphezulu kwe-10 ° C ephezulu kunalokho kwe-pomymerized pom, kepha i-pom evimbela ukushisa isikhathi eside icishe ibe ngu-10 ° C ephakeme kunaleso Ingasetshenziselwa isikhathi eside ebangeni lokushisa le -40 ℃ ~ 100 ℃. I-POM ibolekwe kalula, futhi izinga lokushisa lokubola lingama-240 degrees. Amagesi acasulayo futhi awonakalisayo azokwenzeka ngesikhathi sokubola, ngakho-ke insimbi yokubumba kufanele yenziwe ngezinto zokulwa nokuphikiswa.

(1) I-POM iyipulasitiki ye-crystalline ene-density ye-1.42G / CM3. Ukuqina kwalo kuhle kakhulu, kwaziwa kakhulu ngokuthi "Saigang".

.

. Ukubumba, futhi izinga lokushisa lokushisa lingu-172 ° C. Kunezinhlobo ezimbili ze-polyoxymethylelene, i-homopolymetetelenelene, ngokusebenza okuhlukile (i-homopolyymetetenenenene inokumelana okungcono kokushisa).

Ukucubungula ubuchwepheshe

1. I-POM ayidingi ukomiswa ngaphambi kokucutshungulwa, futhi iyavuswa (cishe ama-80 ° C) ngesikhathi sokucutshungulwa, okulungele ukuqina kosayizi womkhiqizo.

2. Ukushisa okusebenzayo kwe-POM kuncane kakhulu (0 ~ 215 ℃), futhi kuzokubola lapho kuhlala emgqonyeni isikhashana noma izinga lokushisa lidlula igesi ye-formaldehyde.

3. Ingcindezi yokubamba yezinto ezibonakalayo ze-pom kufanele ibe yinkulu (efana nengcindezi yomjovo) ukunciphisa ukwehla kwengcindezi. Ijubane lesikulufo akufanele libe liphezulu kakhulu futhi umthamo osalayo kufanele ube mncane;

4. Imikhiqizo ye-POM inezinga elikhulu le-shrinkage, okulula ukuncipha noma ukungcola. I-POM inokushisa okukhulu kanye nokushisa okuphezulu okuphezulu (80-100 ° C). Umkhiqizo ushisa kakhulu uma kudilizwa, ngakho-ke kuyadingeka ukuvikela iminwe evuthayo.

5. UPom kufanele abunjwe futhi aculiswe ngaphansi kwemibandela ye "Pressure Medium, ijubane eliphakathi nendawo, izinga lokushisa eliphansi, izinga lokushisa eliphakeme" kuyadingeka lapho kubunjwe imikhiqizo enobumba.

6. I-POM inamandla amakhulu okusebenza nokuqina

7. Amandla okukhathala okuphezulu we-pom

8. Ukumelana nemvelo kwezemvelo, ukumelana okuhle kwezinto eziphilayo ezi-organic

I-9.Pom inokumelana okuqinile kwemithelela ephindaphindwayo, izakhiwo ezinhle zikagesi, ukululama okuhle, ukuzithambisa, ukuqiniseka okuhle, ukumelana kahle nokuqina okuhle.

Esebenza njenge-ejenti yePom American DuPont 100p: Isingeniso Esiyisisekelo Nokucubungula Ubuchwepheshe bePom

I-Polyacetal Resin (POM) yi-PuPET's Performer Perfect United Perfectiven Business Unit-Redified Pordified Pordified Pormied POM, engahlangabezana nezidingo eziqinile zomkhakha wezimoto we-Interior Plastics. Lokhu kunweba ukusetshenziswa kweDelrin? I-POM Resin ezimotweni eziya ezimotweni zepulasitiki ezingaphakathi ukuze zibhekane nezidingo zemithwalo yethonya ephezulu.

Imboni ye-auto

I-PolyoxyMethylene isetshenziswa kabanzi embonini yezimoto. Lezi zingxenye ezenziwe nge-polyoxymethylene zinemiphumela emihle njengokunciphisa amaphuzu africation, ukugqokwa kokudla, ukulungiswa okulula, ukwenza lula ukwakheka, ukunciphisa izindleko, ukonga izinto zethusi. Ukufakwa esikhundleni kwe-Copper ukukhiqizwa kwama-half-shaft namagiya weplanethi ezimotweni akugcini nje ngokusindisa ithusi, kodwa futhi kwandisa impilo yenkonzo. Ohlelweni lwenjini kaphethiloli, i-POM ingakhiqiza izingxenye ezifana nama-radiator wamapayipi wamapayipi, amathangi e-radiator, izimbotshana zamanzi, izindlu zethangi lamanzi, izindlu ze-vaporizer, izinyawo ze-accelerator kanye nezinye izingxenye.

Izinto zikagesi ze-elekthronikhi

Ngenxa yokusetshenziswa kwayo okuphansi kwamandla, amandla aphezulu we-dielectric kanye nokumelana nokufakelwa, kanye nokumelana kwe-arc, i-polyoxymethylene isetshenziswe kabanzi emkhakheni we-elekthronikhi kanye nemishini kagesi. Isibonelo, i-polyoxymethylenenene ingasetshenziswa ukukhiqiza amagobolondo okuwa magesi kagesi, amagobolondo kagesi kagesi amagobolondo, amagobolondo okushayela amalahle bese ashintshela, kanye nezingcingo ze-tepi, ama-televil, izingxenye zekhompyutha kanye ne-FAX kanye ne-FAX kanye ne-FAX PASE METER MADE, TELEVEL izingxenye, amarekhodi wetheyiphu, njll. Isihlalo.

Ukwakha: Ingasetshenziswa njengomompompi, ozimele windows, izitsha zokugeza, amathangi amanzi, ama-curtain pulleys, amagobolondo wamamitha wamanzi namajoyitela wamapayipi amanzi, njll.

Imishini Yezolimo: Izingxenye ze-Manual Sprayer, ukuxhumana kanye nezingxenye ze-intertodal of Planter, izindlu ezishukumisayo zomshini wamanzi kanye nokunisela kanye nezindawo zemikhono, njll. Kungasetjenziselwa futhi kupakisha we-aerosol, Ukudlulisa amapayipi, izingxenye ezigxile emafutheni, kanye namaphaneli ajwayelekile wokumelana, njll. Kungakunqoba ukulula kwe-PTFE emsulwa

I-POM ine-coefficient ephansi kakhulu yokuxabana nokuqina okuhle kwejometri, ilungele ikakhulukazi ukwenza amagiya kanye ne-bearings. Ngoba futhi inokumelana okuphezulu okushisa okuphezulu, isetshenziswa futhi kumadivayisi wepayipi (ama-palve amaphampu, izindlu zepompo)
