Misonkhano yapulasitiki ya pulasitiki imapezeka pom Delrin

Hony® Polymethylene ndi pulasitiki ya thermoplasting ndi magwiridwe antchito abwino kwambiri. Magwiridwe ake ndi ochepera pa naylon, koma mtengo wake ndi wotsika kuposa nylon. Pulyacetal ufa ndi ufa woyera, pambuyo potupa, ndi chikasu chachikaso kapena choyera, chonyezimira komanso chonyezimira. Polyoxymethylene ali ndi vuto lalikulu komanso compressive katundu komanso kutopa kwambiri, ndipo ndikoyenera makamaka ku zida zobwereza zakunja kwa nthawi yayitali. Polyoxymethylene ali ndi miyeso yokhazikika, yamadzi ochepa amadzi, komanso kuchepa kwanyengo komanso kuvala kukana. Magwiridwe; Titha kupirira kutsekeredwa, kukhala ndi luso labwino, lingagwiritsidwe ntchito kupanga zinthu zamapulasitiki; Nthawi zambiri osasunthika mu kutentha kwa firini, amatha kupirira Aldeydes, esters, ma hydrocarbons komanso ofooka, koma osalimbana ndi asidi wamphamvu; ili ndi katundu wabwino wamagetsi. Choyipa cha Polyoxymethylene ndikuti ali ndi mtengo waukulu wowumba komanso kukhazikika kwamatenthedwe pamatenthedwe.

Ntchito zambiri

Polyoxymethylene ndi zinthu zolimba komanso zowoneka bwino komanso zonyezimira, zachikasu kapena zoyera, ndipo gawo loonda limakhala lopondera. Mitundu yotentha ndiyosavuta kuwotcha, ndikupitiliza kutentha mutachoka pamoto. Kumapeto kwa lawi ndi chikasu, ndipo kumapeto kwake ndi kwamtambo. Kusungunuka ndi kukhetsa kumachitika, ndipo pali fungo lamphamvu lamphamvu kwambiri komanso fungo la nsomba. Polyoxymethylene ndi ufa woyera, nthawi zambiri zokongoletsa, mphamvu yokongola (yamphamvu yapadera 1.41 g / masentimita), kuwumba mizere 80-90 ℃ kwa maola awiri. Kuwiritsa kwa poms kwa nthawi yayitali ku Pom sikokwanira, koma kumatha kufikira 160 ° C nthawi yochepa. Kuletsa kwakanthawi kochepa kwa poms a homopolymermerized pom ndi opitilira 10 ° C okwera kuposa poms, koma poms-cuolymer over-° ndi pafupifupi 10 ° Itha kugwiritsidwa ntchito kwa nthawi yayitali mu kutentha kwa -40 ℃ ~ 100 ℃. Pom imapangidwa mosavuta, ndipo kutentha kwa madigiri 240. Mipweya yopweteka komanso yowononga idzachitika nthawi yomwe phokoso limachitika, kotero chitsulo chowuma chimayenera kupangidwa ndi zida zosagonjetseka.

(1) Pom ndi pulasitiki ya Crystalline ndi kachulukidwe ka 1.42g / cm3. Kukhazikika kwake ndikwabwino kwambiri, kumadziwika kuti "saigang".

.

(3) Pom siosavuta kuyamwa chinyezi, mayamwidwe amadzi ndi 0,22 ~ 0.25%, kukula kwake kumakhala kovuta, komanso kuchuluka kwake), kukula kwake ndikovuta kuwongolera nthawi jakisoni Kuumba, ndipo kutentha kwa kutentha kumakhala 172 ° C. Pali mitundu iwiri ya polymohylene, homopolymoxymethylene, yogwirira ntchito yosiyanasiyana (homopolyoxymethylene akukana kutentha).

Kukonza ukadaulo

1. POM sikufunika kuwuma musanakonzedwe, ndipo imakonzekereratu (pafupifupi 80 ° C) pakukonzanso, zomwe ndizabwino kukhazikika kwa kukula kwa malonda.

.

3. Kupanikizika kwa zinthu za pa pom kuyenera kukhala kwakukulu (zofanana ndi kupanikizika kwa jakisoni) kuti muchepetse kupanikizika. Kuthamanga kokhazikika sikuyenera kukhala lalitali kwambiri komanso voliyumu yoyenera iyenera kukhala yaying'ono;

4. Zogulitsa za POM zimakhala ndi kuchuluka kwakukulu, komwe kumakhala kosavuta kapena kusokonekera. Pom ali ndi kutentha kwakukulu komanso kutentha kwambiri kwa nkhungu (80-100 ° C). Chogulitsacho chimatentha kwambiri ikawonongedwa, motero ndikofunikira kuti apewe zala zoyaka.

5. Pom iyenera kuumbidwa ndikukonzedwa pansi pa zochitika za "kupanikizika pang'ono, kuthamanga kwapakati, kutentha kwambiri kwamphamvu, kutentha kwambiri kuwumbika kumafunikira pamene zowongolera zimapangidwira.

6. Pom ali ndi mphamvu zapamwamba komanso zolimba

7. Kutalika Kwambiri

8. Pom Chilengedwe, kukana kwabwino kwa ordom

Pam ili ndi kukana mwamphamvu kuti musinthe mobwerezabwereza, katundu wabwino wamagetsi, kuchira bwino, kudzikola kwanu, kuvala bwino kukana, komanso kukhazikika kwabwino kwambiri.

Kuchita ngati wothandizira wa Pom American Dund Orp: Kuyambitsa koyamba ndi ukadaulo wa pom

Polyacetal Resin (Pom) ndi poms yoyambirira yosinthika yosinthika, yomwe ingakwaniritse zofuna zazofunikira za makampani ogulitsa zamagalimoto omwe ali ndi mapulaneti amkati. Izi zikuwonjezera kugwiritsa ntchito kwa Delrin? Pom Resin pamagalimoto kupita kumagawo amkati mwa pulasitiki kuti muthane ndi zofunikira zazikulu.

Makampani auto

Polyoxymethylene amagwiritsidwa ntchito kwambiri pamakampani agalimoto. Ziwalo zopangidwa ndi polyoxymethylene ali ndi zotsatira zabwino monga momwe amachepetsa mfundo zopangira mafuta, kuvala mosavuta, kapangidwe kake kake, kumachepetsa mphamvu, ndikupulumutsa ndalama. Zosintha zamkuwa kuti mupange theka la shaft ndi magiya a mapulaneti pagalimoto sizimangopulumutsa mkuwa, komanso moyo wa ntchito. Mu mafuta mafuta, Gome amatha kupanga zigawo monga ma radiator chipika cha radiator, matupi ozizira, matupi a mafuta, ma trasortorator.

Zida zamagetsi

Chifukwa cha kugwiritsa ntchito mphamvu zake zochepa, mphamvu zapamwamba za sekondale komanso kukana kwa arc, ndi arc kukana, polyoxymethylene wagwiritsidwa ntchito kwambiri pamunda wamakompyuta ndi zida zamagetsi. Mwachitsanzo, polyoxymethylene itha kugwiritsidwa ntchito kupanga zipolopolo zamagetsi, zipolopolo za malasha za malasha ndi kusintha mapepala, mavidiyo, mafilimu amakompyuta, Timer magawo, zojambulira tepi, mpando wa etc.

Ntchito: Itha kugwiritsidwa ntchito ngati mapiko, mafelemu a pawindo, masitima otsuka, masitima amadzi, zotupa zamadzi, zolumikizira madzi, etc.

Makina Olima Mapaipi operekera, magawo adamizidwa mu mafuta, ndi ma Panels okhazikika, etc. amatha kuthana ndi chiletso cha PTF

Pom ali ndi zolimba kwambiri mu mkangano komanso kukhazikika kwa geometric, koyenera kupanga magiya ndi mafinya. Chifukwa ilinso kukana kutentha kwambiri, kumagwiritsidwanso ntchito pazithunzi (ma vani ya ziphuphu,)
