Wolemba Andy wochokera ku fakitale ya Baiyear
Idasinthidwa Novembala 2, 2022
Nawa likulu la nkhani zamakampani opanga jakisoni a Baiyear.Kenako, Baiyear agawa njira yopangira jekeseni muzolemba zingapo kuti adziwe kusanthula kwa zida zopangira jekeseni, chifukwa pali zambiri.Chotsatira ndi nkhani yachisanu ndi chimodzi.
(14).PPO (polyphenylene ether)
1. Kuchita kwa PPO
Polyphenylene oxide ndi poly-2,6-dimethyl-1,4-phenylene oxide, yomwe imadziwikanso kuti polyphenylene oxide, dzina la Chingerezi Polyphenyleneoxiole (lotchedwa PPO), polyphenylene ether yosinthidwa imasinthidwa ndi polystyrene kapena ma polima ena.Sexual polyphenylene ether, yotchedwa MPPO.
PPO (NORLY) ndi pulasitiki yauinjiniya yokhala ndi zinthu zabwino kwambiri.Ili ndi kuuma kwakukulu kuposa PA, POM ndi PC, mphamvu zamakina apamwamba, kukhazikika bwino, kukana kutentha kwabwino (kutentha kwa kutentha ndi 126 ℃), komanso kukhazikika kwapamwamba (kutentha kocheperako).mlingo wa 0.6%), mayamwidwe otsika madzi (osakwana 0.1%).Choyipa chake ndikuti sichikhazikika ku kuwala kwa ultraviolet, mtengo wake ndi wokwera, ndipo mlingo wake ndi wochepa.
PPO ndi yopanda poizoni, yowonekera, imakhala ndi kachulukidwe kakang'ono, ndipo imakhala ndi mphamvu zamakina, kukana kumasuka, kukana kugwa, kukana kutentha, kukana madzi, komanso kukana nthunzi wamadzi.Makhalidwe abwino amagetsi pamitundu yosiyanasiyana ya kutentha ndi kusinthasintha kwafupipafupi, palibe hydrolysis, shrinkage yaying'ono, yoletsa moto komanso yozimitsa yokha, yosakanizidwa ndi ma inorganic acid, ma alkali, ma hydrocarbon onunkhira, ma halogenated hydrocarbon, mafuta, ndi zina zambiri, zosavuta kutupa Kapena kupsinjika maganizo, kuipa kwakukulu ndi kusungunula kosasunthika kosasunthika, kukonza kovuta ndi kupanga, ntchito zambiri zothandiza ndi MPPO (PPO blends kapena alloys), monga PS kusinthidwa kwa PPO, ikhoza kupititsa patsogolo ntchito yokonza, kupititsa patsogolo kukana kwachisokonezo ndi kukhudzidwa. kukana Magwiridwe, kuchepetsa mtengo, kuchepetsa pang'ono kukana kutentha ndi gloss.
Ma polima osinthidwa akuphatikizapo PS (kuphatikiza HIPS), PA, PTFE, PBT, PPS ndi ma elastomers osiyanasiyana, polysiloxane, PS yosinthidwa PPO parafini, chinthu chachikulu kwambiri, MPPO ndiye makina ogwiritsidwa ntchito kwambiri a pulasitiki aloyi.Mitundu yayikulu ya MPPO ndi PPO/PS, PPO/PA/elastomers ndi PPO/PBT elastomer alloys.
2. Makhalidwe a PPO:
PPO ili ndi kukhuthala kwamphamvu kwambiri, kusayenda bwino kwamadzi, komanso kusintha kwakukulu.Musanayambe kukonza, iyenera kuumitsidwa pa kutentha kwa 100-120 ° C kwa maola 1-2, kutentha kwa nkhungu ndi 270-320 ° C, ndipo kutentha kwa nkhungu kumayendetsedwa bwino pa 75-95 ° C.kukonza.Popanga pulasitiki ya mowa wa pulasitiki iyi, mawonekedwe a jet flow (mtundu wa serpentine) ndiosavuta kupangidwa kutsogolo kwa mphuno, ndipo njira yotuluka ya mphunoyo imakhala yokulirapo.
Makulidwe ocheperako amachokera ku 0.060 mpaka 0.125 mainchesi pamawumbidwe wamba ndi mainchesi 0.125 mpaka 0.250 a thovu zamapangidwe, komanso kuyaka kumayambira UL94 HB mpaka VO.
3. Mtundu wofananira wa ntchito:
PPO ndi MPPO akhoza kukonzedwa ndi njira zosiyanasiyana processing monga jekeseni akamaumba, extrusion, kuwombera akamaumba, akamaumba, thobvu ndi electroplating, zingalowe ❖ kuyanika, makina osindikizira processing, etc., chifukwa mkulu kusungunuka kukhuthala ndi kutentha mkulu processing.
PPO ndi MPPO amagwiritsidwa ntchito makamaka pazida zamagetsi, magalimoto, zida zapakhomo, zida zam'ofesi ndi makina opanga mafakitale, ndi zina zambiri, kugwiritsa ntchito MPPO pakukana kutentha, kukana kukhudzidwa, kukhazikika kwazithunzi, kukana kukanda, ndi kukana kupukuta;
Kupaka utoto ndi mphamvu zamagetsi: zomwe zimagwiritsidwa ntchito popanga ma dashboard amagalimoto, ma gridi a radiator, ma grill olankhula, ma consoles, mabokosi a fuse, mabokosi otumizirana, zolumikizira, zophimba mawilo;amagwiritsidwa ntchito kwambiri mumakampani amagetsi ndi zamagetsi kuti apange zolumikizira, ma coil windings Spools, ma switching relay, zida zosinthira, zowonetsera zazikulu zamagetsi, ma capacitor osinthika, Chalk batire, maikolofoni ndi zigawo zina.
Zipangizo zapakhomo zimagwiritsidwa ntchito popanga ma TV, makamera, matepi a kanema, zojambulira matepi, zoziziritsa kukhosi, zotenthetsera, zophika mpunga ndi mbali zina.Itha kugwiritsidwa ntchito ngati mbali zakunja ndi zigawo za makope, makina apakompyuta, osindikiza, makina a fax, etc. Komanso, angagwiritsidwe ntchito ngati kamera, timer, mpope madzi, blower chipolopolo ndi mbali, chete zida, payipi, valavu thupi, chida opaleshoni, sterilizer ndi zida zina zachipatala zida.
Kumangirira kwakukulu kumatha kugwiritsidwa ntchito pamagalimoto akulu akulu monga owononga, ma bumpers, ndi kuumba kopanda thovu.Ndizoyenera kupanga zinthu zazikuluzikulu zomwe zimakhala zolimba kwambiri, kukhazikika kwazithunzi, kuyamwa kwabwino kwambiri, komanso zomangira zovuta zamkati, monga zipolopolo zamakina osiyanasiyana, zoyambira, zamkati Mabulaketi ndi mapangidwe ali ndi ufulu waukulu, ndipo mankhwalawa ndi opepuka.
(15).PBT polybutylene terephthalate
1. Kachitidwe ka PBT:
PBT ndi imodzi mwama engineering thermoplastics ovuta kwambiri.Ndi semi-crystalline zinthu zabwino kwambiri kukhazikika kwa mankhwala, mphamvu makina, magetsi insulating katundu ndi matenthedwe bata.Zidazi zimakhala ndi kukhazikika kwabwino m'malo osiyanasiyana a chilengedwe, ndipo PBT ili ndi katundu wofooka kwambiri wa hygroscopic.Kulimba kwamphamvu kwa PBT yosalimbitsa ndi 50MPa, ndipo kulimba kwamtundu wowonjezera wa galasi PBT ndi 170MPa.Kuchuluka kwa magalasi owonjezera kumapangitsa kuti zinthuzo ziwonongeke.
PBT;crystallization ndi yofulumira kwambiri, yomwe imayambitsa kupindika chifukwa cha kuzizira kosiyana.Pazinthu zokhala ndi zowonjezera zamagalasi, kuchepa kwa njira yoyendetsera njira kumatha kuchepetsedwa, koma kutsika komwe kumayenderana ndi njirayo kumakhala kofanana ndi zida wamba.
Chiwopsezo chambiri chocheperako chili pakati pa 1.5% ndi 2.8%.Zida zomwe zili ndi 30% zowonjezera magalasi zimachepa pakati pa 0.3% ndi 1.6%.Malo osungunuka (225% ℃) ndi kutentha kwakukulu kwa kutentha kumakhala kotsika kuposa zinthu za PET.Kutentha kwa Vicat kumakhala pafupifupi 170 ° C.Kutentha kwa kusintha kwa galasi (glass trasitiotemperature) kuli pakati pa 22°C ndi 43°C.
Chifukwa cha kuchuluka kwa crystallization ya PBT, kukhuthala kwake ndikotsika kwambiri, ndipo nthawi yozungulira ya magawo apulasitiki nthawi zambiri imakhala yotsika.
2. Makhalidwe a PBT:
Kuyanika: Nkhaniyi imapangidwa mosavuta ndi hydrolyzed pa kutentha kwambiri, kotero kuyanika musanakonzekere ndikofunikira.Analimbikitsa kuyanika zinthu mu mpweya ndi 120C kwa 6 ~ 8 hours, kapena 150C kwa 2 ~ 4 hours.
Chinyezi sayenera kupitirira 0.03%.Ngati kuyanika ndi hygroscopic desiccator, zovomerezeka ndi 150 ° C kwa maola 2.5.The processing kutentha ndi 225 ~ 275 ℃, ndi kutentha analimbikitsa ndi 250 ℃.Kwa zinthu zosalimbitsa, kutentha kwa nkhungu ndi 40 ~ 60 ℃.Njira yozizira ya nkhungu iyenera kukonzedwa bwino kuti ichepetse kupindika kwa gawo la pulasitiki.Kutentha kwa kutentha kuyenera kukhala kofulumira komanso kofanana.
M'mimba mwake wa njira yozizira ya nkhungu ndi 12mm.Kuthamanga kwa jakisoni kumakhala kocheperako (mpaka 1500bar), ndipo liwiro la jakisoni liyenera kukhala lachangu momwe mungathere (chifukwa PBT imalimba mwachangu).Wothamanga ndi chipata: Ndikoyenera kugwiritsa ntchito wothamanga wozungulira kuti awonjezere kufalikira kwa kupanikizika (chilinganizo chokumana nacho: wothamanga m'mimba mwake = makulidwe a gawo la pulasitiki + 1.5mm).
Mitundu yosiyanasiyana ya zipata ingagwiritsidwe ntchito.Othamanga otentha angagwiritsidwenso ntchito, koma chisamaliro chiyenera kutengedwa kuti chiteteze kutayikira ndi kuwonongeka kwa zinthu.Kutalika kwa chipata kuyenera kukhala pakati pa 0.8 ~ 1.0 * t, pomwe t ndi makulidwe a gawo la pulasitiki.Ngati ndi chipata chomizidwa m'madzi, m'mimba mwake osachepera 0.75mm akulimbikitsidwa.
3. Mtundu wofananira wa ntchito:
zida zapakhomo (masamba opangira chakudya, zida zotsukira, mafani amagetsi, zowumitsira tsitsi, ziwiya za khofi, ndi zina), zida zamagetsi (ma switch, ma motor housing, mabokosi a fuse, makiyi a kiyibodi apakompyuta, etc.), Industrial yamagalimoto (radiator grilles, mapanelo a thupi, zotchingira magudumu, zitseko ndi mazenera zigawo, etc.
Chidziwitso chochuluka chayambitsidwa m'derali.Kuti mudziwe zambiri, Baiyear isintha posachedwa.Tidzasintha nthawi zonse zopangira pulasitiki, jekeseni wopangira jekeseni, kuyambitsa zida zopangira jekeseni, mapangidwe a nkhungu, kujambula nkhungu, kuyambitsa makina opangira nkhungu, kukonza zitsulo, Kudziwa nkhani za kupanga bokosi logawa, kupanga bokosi lachitsulo, kuyambitsa zida zopangira zitsulo, kusalowa madzi. bokosi lolumikizirana, chivundikiro chawindo chopanda madzi, ndi zina. Ngati mukufuna kudziwa zomwe zili pamwambapa, mutha kulumikizana nane nthawi iliyonse, ndidzakhala wokondwa kukutumikirani ndikuyembekezera kubwera kwanu.
