Polyoxymethylene (POM) Resin: Kugadzirazve Kwepamusoro-soro Kwemakona Kwemaindasitiri
Kuongorora Mashandiro: Hunhu Hwakanaka Hunopa Mabhenefiti Akasiyana-siyana
Simba Rinoshamisa reMichina
Simba reKubata: 60–70 MPa, yakafanana nezvimwe zvinhu zvesimbi, zvichiita kuti irambe ichidzivirira kuputsika kana yanyanya kumanikidzwa.
Modulus Inokotama: 2.5–3.0 GPa, inopa rutsigiro rwakasimba rwechimiro chezvikamu zvinotakura mutoro.
Kusapfeka: Kusashanda zvakanaka kwemuchina (0.1–0.3 kana wakaoma) kunoita kuti zvive zvakanaka pakutsvedza/kutenderera zvikamu zvakaita semagiya, mapulley, uye masprocket, zvichideredza kusakara uye kuwedzera hupenyu hwemuchina.
Kuramba Kuneta: Inotsungirira mamiriyoni emitambo yekushushikana isingakundike, yakakodzera zvikamu zvinomiswa kutanga kana kurodha nguva nenguva.
Kugadzikana Kwakanaka Kwemakemikari
POM inodzivirira zvinonyungudutsa, mafuta, maasidhi asina simba, uye maalkali, ichichengetedza kunaka kwayo munzvimbo dzakaoma dzemakemikari. Semuenzaniso, munzvimbo dzeinjini dzemotokari, zvikamu zvePOM (semuenzaniso, magiya epombi yemafuta) zvinotsungirira mafuta emota, chinotonhodza, uye tembiricha yakakwira pasina kuzvimba kana ngura. Zvisinei, inogona kuora kana paine maasidhi akasimba, maalkali, kana hunyoro hwepamusoro.
Kushanda Kwekupisa Kwakavimbika
Kupisa Kunochinja Kupisa: 136–162°C (mutoro uri pasi pe0.45 MPa), nekupisa kunogara kuchishandiswa kwe85–105°C, kwakakodzera kushandiswa kunoda kudzivirira kupisa kuri pakati nepakati.
Kufambisa Kwekupisa Kwakaderera: 0.22–0.35 W/(m·K), zvichipa hunhu hwekudzivirira kupisa mumidziyo yemagetsi.
Kudzivirira Kwemagetsi Kwepamusoro
Kudzivirira Vhoriyamu: 10¹³–10¹⁴ Ω·cm, ine dielectric constant ye3.7–3.9 (pa1 MHz), ichichengetedza kushanda kwakasimba kwekudzivirira mukati memazinga ekupisa/hunyoro uye mafrequency band.
Mashandisirwo: Yakanakira zvikamu zvemagetsi zvakaita semaswichi, mabhuroko emagetsi, uye mahosi emagetsi, zvichideredza njodzi dzekubuda kwemvura kana mashort circuits.
Kugadziriswa Kunoenderana Nezvinhu Zvakawanda
Kunyunguduka kwakanaka kwePOM kunogonesa kugadzirwa kwakanyatsojeka kuburikidza nekupinza, kuburitsa, kuputira, nezvimwewo, nenguva pfupi yekutenderera uye kushanda zvakanaka. Izvi zvinoita kuti ive yakakodzera zvikamu zvinogadzira huremu hwakawanda, zvichisangana nekudiwa kwemaindasitiri nekukurumidza.
Minda Yekushandisa: Kupinda Kwakafara Kunosimudzira Kuvandudzwa Kwemaindasitiri
Indasitiri yeMotokari: Rutsigiro Rwakavimbika rweZvikamu Zvakakosha
Sisitimu yeInjini: Magiya epombi yemafuta akagadzirwa nePOM anoita kuti mafuta ashande zvakanaka kana mafuta acho akanyanya kumanikidzwa, nekuda kwekukweshana kwakaderera, kuramba kupfeka, uye kugadzikana kwemakemikari, zvichiita kuti mafuta asvike zvakanaka.
Sisitimu Yemukati: Zvibato zvemagonhi, magiya ekugadzirisa mahwindo, uye zvinhu zvinogadzirisa zvigaro zvinoshandisa simba rePOM kuti ishande zvakanaka uye igare kwenguva refu, nepo kugona kwayo kugadzira kuchibvumira mikana yakasiyana-siyana yekugadzira.
Sisitimu Yekutumira: Mapulleys enguva uye masprockets akagadzirwa nePOM anotumira simba zvinobudirira pasina kurasikirwa nesimba kwakawanda.
Zvishandiso zveMagetsi neMagetsi: Rutsigiro Ruviri rweKushanda uye Kuchengetedzeka
Dzimba dzemidziyo: POM inopa dziviriro yakasimba yemagetsi emukati meimba uku ichivimbisa kuvharwa kwemagetsi (semuenzaniso, mafeni nemafuremu mumasisitimu ekutonhodza emakombiyuta, ayo anochengetedza kugadzikana nekumhanya kwakanyanya pasina kukanganisa zvikamu).
Zvinobatanidza: Zvikamu zvePOM zvinopa kururama kwakanyanya uye kuvimbika, zvakakosha pakuchengetedza kugadzikana kwekubatana kwemagetsi muma connectors.
Michina yeMaindasitiri neMidziyo
Zvikamu zveMichina: Magiya, mabushing, uye mabheringi mumidziyo yeindasitiri zvinobatsira kubva mukusakara kwePOM uye ruzha rwakaderera, zvichideredza zvinodiwa pakugadzirisa uye kuvandudza kushanda zvakanaka.
Mavharuvhu nemapombi: POM inoshandiswa mumapombi emakemikari nemavharuvhu nekuda kwekudzivirira kwayo ngura, yakakodzera kutakura mvura isingaparare mumaindasitiri emishonga nechikafu.
Zvinhu Zvinoshandiswa Nevatengi Nemidziyo Yakanyatsogadzirwa
Zvigadzirwa zveVatengi: Mazipu, magiya ewachi, uye zvikamu zvemidziyo yekicheni (semuenzaniso, magiya eblender) zvinoshandisa POM nekuda kwekugara kwayo kwenguva refu uye kugona kwayo kugadzira zvinhu zvakanaka.
Zvishandiso Zvakarurama: Mumidziyo yekurapa nemidziyo yemaziso, kunyatsojeka uye kugadzikana kwePOM kunoita kuti zvinhu zvakaita semasyringe plunger nemalens mounts zvishande zvakanaka.

Kugadzira uye Kuvimbisa Hunhu
Maitiro Ekugadzira
Kuumbwa kwepolymer: Kugadzirwa kuburikidza ne cationic/anionic polymerization ye formaldehyde, pamwe nekugadziriswa kwe stabilizers kuti kuwedzere kugadzikana kwekupisa.
Kusanganisa: Kunosimbiswa negirazi fiber, kabhoni fiber, kana mafuta ekushandisa kuti agadzire zvinhu (semuenzaniso, girazi-filled POM kuti riwedzere kuomarara kana kuti rinozvizora rega kuti zvisanyanya kukweshana).
Maitiro Emhando Yepamusoro
Kuedzwa kweMichina: Simba rekusimba, kureba panguva yekutyoka, uye modulus yekutenderera yakaedzwa zvichienderana neISO 527 neASTM D638.
Kuedzwa kweThermal: Kupisa kwekupisa (HDT) uye melt flow index (MFI) zvakayerwa zvichienderana neISO 75 neASTM D1238.
Kudzora Kuchena: Heavy metal content
Sei Tichifanira Kusarudza POM Resin Yedu?
Kushanda Kwepamusoro: POM yedu inopa kristallinity inogara iripo (75±5%) uye simba rekudhonza (≥65 MPa), ichipfuura magiredhi akajairwa mukudzivirira kuneta (≥1 miriyoni macycles).
Mhinduro Dzakagadzirirwa: Mafomu akagadzirirwa zvinodiwa chaizvo:
Kuramba Kupisa Kwakanyanya: Magiredhi akachinjwa ekushandiswa nguva dzose kwe120°C muinjini dzemotokari.
Kudzivirira Murazvo: UL 94 V-0 inoenderana nemagiredhi emagetsi.
Kugara kwenguva refu: Magiredhi anogona kushandiswazve (huwandu hwekushandiswazve mushure mekushandiswazve kwemaindasitiri ≥90%) uye kugadzirwa kwekabhoni shoma (kushandiswa kwesimba kwakaderera ne15% zvichienzaniswa neavhareji yemaindasitiri).
Kutevedzera Mutemo Wenyika Yose: Yakatenderwa neISO 9001, FDA (chikafu chinobata), uye RoHS/REACH yemagetsi, nekutumirwa nekukurumidza (mavhiki maviri kusvika mana pasi rose).
Kuvandudzwa kweMapurasitiki eInjini muInjini
Kubva pazvikamu zvakakosha zvemotokari kusvika kumagetsi akagadzirwa nemazvo, POM resin inoramba ichitsanangura patsva zvinogona kuitwa nemapurasitiki einjiniya. Musanganiswa wayo wakasiyana wekushanda kwemakanika, kugona kutsungirira makemikari, uye kushanduka-shanduka kwemaitiro kunoita kuti ive yakakosha mumaindasitiri akasiyana. Sarudza POM yedu kuti ivhure kuvimbika, kushanda zvakanaka, uye hunyanzvi—apo chikamu chimwe nechimwe chinoratidza kubatana kwekushanda kwepurasitiki uye kugara kwenguva refu kwesimbi.
