PPO abu daga SIKO
Polyphenylene oxide ko polyethylene ether Kuma aka sani da polyphenylene oxide ko polyphenylene ether, babban zafin jiki ne mai jure zafin zafi.
Halaye da Aikace-aikace
PPO robobin injiniyan thermoplastic tare da ingantaccen aiki mai mahimmanci, fiyayyen rufin lantarki da juriya na ruwa, da kwanciyar hankali mai kyau.
1, dielectric Properties na injiniya robobi na farko
PPO resin molecular tsarin ba tare da ƙungiyoyin polar masu ƙarfi ba, kaddarorin lantarki masu tsayayye, na iya kula da kyawawan kaddarorin lantarki a cikin kewayon zafin jiki da mita.
① Dielectric akai-akai: 2.6-2.8 shine mafi ƙanƙanta a cikin robobi na injiniya ② Tangent na asarar dielectric Angle: 0.008-0.0042 (kusan zafin jiki ba ya shafa, zafi da mita)
2, kyawawan kayan inji da kaddarorin thermal na sarkar kwayoyin PPO, dauke da adadi mai yawa na tsarin zobe na aromatic, sarkar kwayar halitta tana da karfi, karfin injin guduro yana da girma, kyakkyawan juriya mai rarrafe, canjin zafin jiki kadan ne.PPO yana da tsayayyar zafi mai zafi, zafin canjin gilashin har zuwa 211 ℃, ma'anar narkewa 268 ℃.
3, kyakkyawan juriya na ruwa PPO shine resin ba-crystalline, a cikin kewayon zafin jiki na yau da kullun, ƙarancin motsi na ƙwayoyin cuta, babu manyan ƙungiyoyin polar a cikin babban sarkar, lokacin dipole baya faruwa sandal, juriya na ruwa yana da kyau sosai, shine mafi ƙarancin sha ruwa. na injiniyoyi robobi.Abubuwan da ke cikin jiki har yanzu suna da ƙarancin lalacewa bayan jiƙa a cikin ruwan zafi na dogon lokaci.
4, Oxygen index na PPO mai kashe kansa shine 29, wanda shine kayan kashe kansa, kuma ma'aunin iskar oxygen na babban tasirin polyethylene shine 17, wanda shine abu mai ƙonewa.Haɗin biyun yana da matsakaicin wuta.Lokacin yin PPO mai ɗaukar harshen wuta, babu buƙatar ƙara halogen flame retardant, ƙara adadin zafin wuta mai ɗauke da phosphorus zai iya kaiwa daidaitattun UL94.Rage gurbatar yanayi ga muhalli.
5, ƙananan raguwa, kwanciyar hankali mai kyau;Ba mai guba ba, ƙananan ƙarancin 6, juriya na dielectric da haske juriya PPO acid, alkali da detergent da sauran lalatawar asali, a ƙarƙashin yanayin damuwa, man fetur da ketone, masu kaushi na ester zai haifar da damuwa;Abubuwan kaushi na halitta kamar aliphatic hydrocarbons, halogenated aliphatic hydrocarbons da kamshi hydrocarbons na iya narke da narkewa.
Rashin ƙarfi na PPO shine ƙarancin juriya na haske, dogon lokaci a ƙarƙashin hasken rana ko amfani da fitilar fitila yana haifar da canza launi, launin rawaya, dalilin shine hasken ultraviolet na iya sanya sarkar ether ke raba.Yadda za a inganta juriyar haske na PPO ya zama batu.
Ayyukan PPO yana ƙayyade filin da iyakokin aikace-aikacen:
①MPPO yawa ne kananan, sauki aiwatar, thermal nakasawa zafin jiki a 90-175 ℃, akwai daban-daban bayani dalla-dalla na kaya, mai kyau girma da kwanciyar hankali, dace da yi na ofishin kayan aiki, iyali kayan, kwamfuta kwalaye, chassis da daidaici sassa.
② MPPO dielectric akai-akai da dielectric asarar Angle tangent a cikin manyan robobi na injiniya guda biyar a cikin mafi ƙasƙanci, wato, mafi kyawun rufi, da kuma kyakkyawan juriya na zafi, dace da masana'antun lantarki.Ya dace da yin sassa masu hana wutan lantarki, kamar firam ɗin murɗa, mai riƙe bututu, sandar sarrafawa, hannun garkuwar wuta, akwatin ba da sanda, ginshiƙan insulating da sauransu, waɗanda ake amfani da su a cikin yanayin jika da lodi.
③ MPPO yana da kyakkyawan juriya na ruwa da juriya na zafi, wanda ya dace da yin mita na ruwa, famfo ruwa da bututun yarn da ake amfani da su a masana'antar yadi waɗanda ke buƙatar samfuran mabukaci masu ɗorewa don dafa abinci.Bututun yarn da aka yi da MPPO suna da tsawon rayuwar sabis.
④ Dielectric m da dielectric asarar Angle tangent na MPPO ba su shafar zafin jiki da lambar sake zagayowar a cikin robobi na injiniya, kuma suna da tsayayyar zafi mai kyau da kwanciyar hankali, wanda ya dace da masana'antun lantarki.
