Mawu Oyamba
PPO, monga imodzi mwa mapulasitiki akuluakulu asanu a uinjiniya, ndi chinthu chokhwima kwambiri pakampani yathu. PPO, (polyphony ether)
Zili ndi ubwino wokhazikika kwambiri, kukana kutentha kwakukulu, zovuta kuwotcha, mphamvu zapamwamba komanso ntchito zabwino kwambiri zamagetsi. Kuonjezera apo, polyether imakhalanso ndi ubwino wa kuvala - kugonjetsedwa, osati - poizoni, anti - kuipitsa ndi zina zotero.
Kutayika kwa PPO dielectric ndi dielectric mu mapulasitiki a uinjiniya ndi imodzi mwamitundu yaying'ono kwambiri, yosakhudzidwa ndi kutentha, chinyezi, ingagwiritsidwe ntchito m'munda wamagetsi otsika, apakatikati, apamwamba kwambiri.
Kachitidwe
1. Tinthu zoyera. Kuchita bwino kokwanira kumatha kugwiritsidwa ntchito mu nthunzi ya digirii 120, kutchinjiriza kwamagetsi kwabwino, kuyamwa kwamadzi pang'ono, koma chizolowezi chosweka mtima. Kupsinjika maganizo kumatha kuthetsedwa ndi kusinthidwa kwa polyphenylene ether.
2. Kutsekemera kwabwino kwa magetsi ndi kukana madzi, kukana kuvala bwino ndi ntchito zamagetsi, kukhazikika kwabwino kwa mawonekedwe. Katundu wake wa dielectric amakhala pamalo oyamba mu mapulasitiki.
3, MPPO ndi zinthu zosinthidwa zomwe zimapangidwa posakaniza PPO ndi HIPS, pakadali pano zida zomwe zili pamsika ndizinthu zotere.
4, ali mkulu kutentha kukana, vitrification kutentha madigiri 211, kusungunuka mfundo 268 madigiri, Kutentha kwa madigiri 330 kuwonongeka chizolowezi, okhutira PPO ndi apamwamba kutentha kukana ndi bwino, mapindikidwe matenthedwe kutentha kufika madigiri 190.
5. Zabwino zoletsa moto, zodzikonda, komanso kuyaka kwapakatikati mukasakanikirana ndi HIPS. Kulemera kopepuka, kopanda poizoni kungagwiritsidwe ntchito m'makampani azakudya ndi mankhwala. Osauka kuwala kukana, nthawi yaitali padzuwa kusintha mtundu.
6. Ikhoza kusakanikirana ndi ABS, HDPE, PPS, PA, HPS, galasi CHIKWANGWANI, etc.
PPO pulasitiki zopangira zinthu
A. PPO zopangira pulasitiki zopanda poizoni, zowonekera, zocheperako pang'ono, zokhala ndi mphamvu zamakina kwambiri, kukana kupumula kupsinjika, kukana kuyandama, kukana kutentha, kukana madzi, kukana madzi, kukana kwa nthunzi, kukhazikika kwamkati.
B, mu osiyanasiyana kutentha ndi kusinthasintha pafupipafupi, ntchito zabwino magetsi, palibe hydrolysis, kupanga shrinkage mlingo ndi yaing'ono, choyaka ndi kudziletsa kuzimitsa, osauka kukana asidi inorganic, zamchere, onunkhira hydrocarbon, halogenated hydrocarbon, mafuta ndi katundu wina, kutupa kosavuta kapena kupsinjika maganizo.
C. Ili ndi ubwino wokhazikika kwambiri, kukana kutentha kwakukulu, zovuta kuwotcha, mphamvu zapamwamba komanso ntchito yabwino kwambiri yamagetsi.
D. Polyether imakhalanso ndi ubwino wa kukana kwa abrasion, kusakhala ndi kawopsedwe komanso kukana kuipitsa.
E. PPO pulasitiki zopangira dielectric mosalekeza ndi dielectric imfa mu pulasitiki zomangamanga ndi imodzi mwa mitundu yaing'ono, pafupifupi osakhudzidwa ndi kutentha, chinyezi, angagwiritsidwe ntchito m'munda wa otsika, sing'anga, mkulu pafupipafupi magetsi kumunda.
F. PPO katundu deformation kutentha akhoza kufika pamwamba 190 ℃, embrittlement kutentha ndi -170 ℃.
G. choyipa chachikulu ndi kusasungunuka kwamadzimadzi, kukonza ndi kuumba zovuta.
Kugwiritsa ntchito
Magwiridwe a PPO amatsimikizira gawo lake logwiritsira ntchito ndikugwiritsa ntchito:
1) MPPO ali kachulukidwe yaing'ono, yosavuta pokonza, matenthedwe mapindikidwe kutentha mu 90 ~ 175 ℃, specifications zosiyanasiyana za katundu, wabwino dimensional bata, oyenera kupanga zida ofesi, zipangizo zapakhomo, makompyuta ndi mabokosi ena, galimotoyo ndi mbali mwatsatanetsatane.
2) Dielectric constant and dielectric loss Angle tangent ya MPPO ndi yotsikitsitsa pakati pa mapulasitiki asanu a engineering general, ndiko kuti, kutchinjiriza kwabwino komanso kukana kutentha kwabwino, koyenera makampani amagetsi.
Zoyenera kupanga zida zotchinjiriza zamagetsi zomwe zimagwiritsidwa ntchito ponyowa komanso zodzaza, monga chimango cha coil, chubu base, shaft yowongolera, chishango cha transformer, bokosi lopatsirana, cholumikizira, ndi zina zambiri.
3) MPPO madzi kukana ndi kutentha kukana, madzi abwino, oyenera kupanga mamita madzi, mapampu.
Chubu cha ulusi chomwe chimagwiritsidwa ntchito mufakitale ya nsalu chiyenera kukhala chosagwira manambala. Chubu chopangidwa ndi MPPO chimakhala ndi moyo wautali wautumiki.
4) Kutayika kwa dielectric nthawi zonse ndi dielectric Angle tangent ya MPPO mu mapulasitiki a uinjiniya samakhudzidwa ndi kutentha ndi kuchuluka kwa ma frequency, komanso kukana kutentha ndi kukhazikika kwapakatikati ndikwabwino, koyenera makampani amagetsi.
5) chifukwa cha chitukuko cha zamagetsi ndi mauthenga makampani, mafoni, Malaputopu, mkulu-ntchito kamera, kamera ndi zina zotero ayenera mabatire lithiamu-ion, lithiamu-ion batire msika chiyembekezo chachikulu chitukuko, Choncho, mabatire lithiamu ion ndi electrolyte organic. wa zipangizo ma CD ntchito ABS kapena PC, anayamba batire MPPO kunja mu 2013, ntchito yake ndi bwino kuposa awiri akale.
6) MPPO ili ndi machitidwe osiyanasiyana ogwiritsira ntchito magalimoto, monga dashboard, mipiringidzo yotetezera, PPO ndi PA alloy, makamaka chifukwa cha kukhudzidwa kwakukulu kwa magwiridwe antchito a chitukuko chofulumira cha zigawo.
7) M'makampani opanga mankhwala, polyphenylene ether yosinthidwa ingagwiritsidwe ntchito kupanga zida zolimbana ndi dzimbiri; kukana kwake kwa hydrolysis makamaka zabwino, komanso asidi, zamchere, sungunuka mu onunkhira hydrocarbon ndi chlorinated hydrocarbon.
8) Pazida zamankhwala, zitha kulowetsa zitsulo zosapanga dzimbiri ndi zitsulo zina mu thanki yosungiramo madzi otentha ndi valavu yotulutsa zotulutsa zotulutsa.
