Nhanganyaya yePolyoxymethylene (POM)

Polyoxymethylene (POM), inozivikanwawo seacetal, polyacetal, kana polyformaldehyde, ipurasitiki yeinjiniya inoshanda zvakanyanya inozivikanwa nehunyanzvi hwayo hwemakanika uye kugadzikana kwayo. Inoshandiswa zvakanyanya mumaindasitiri anoda kunyatsorongeka uye kugara kwenguva refu, senge mota, zvemagetsi, zvekurapa, uye zvinhu zvevatengi.

IyoTekinoroji yePOM Inogara Yakasimba: Magiredhi mapfupi eCellulose Fiber Akasimbiswa

Polyplastics ichangobva kuburitsa mhando itsva yeDURACON® POM grades yakasimbiswa nefuruu pfupi dzecellulose. Iyi nzira itsva inotarisa kudiwa kuri kukura kwezvinhu zvinogara kwenguva refu pasina kukanganisa mashandiro. Kusiyana nePOM yemazuva ano yakazadzwa negirazi, idzi furuu pfupi dzecellulose fiber-reinforced grades dzinowedzera zvakanyanya flexural modulus uku dzichiramba dzakareruka uye dzakasimba.

Cellulose, chinhu chisingadyike, chakavakirwa pahupenyu, chinobatsira mukuchengetedza nharaunda uye chinozivikanwa sechinhu chisina kabhoni chinotora CO2. Kana chakabatanidzwa nesimbi yekabhoni (S45C), aya maPOM grades matsva anoratidza dynamic friction coefficient yakaderera uye kusakara kwakaderera, zvichiita kuti zvive zvakanaka pakushandiswa kwakasimba kunoda kuomarara kwakanyanya uye hunhu hwakanaka hwekutsvedza.

Tingawedzera sei kusakara kwePOM tisingakanganisi kushanda kana kugara kwenguva refu?

Kugadzirisa Matambudziko Ekupfeka Uye Kukweshana muPOM

Pasinei nekufambira mberi uku, zvinhu zvakawanda zvePOM zvichiri kusangana nematambudziko makuru ekusakara nekukweshana, kunyanya mukushandiswa kwakawanda senge mota, zvemagetsi, uye zvinhu zvevatengi.

Zvimwe zvezvakanyanyanzira dzakajairika dzinoshandiswa kuwedzera kuramba kwePOMzvinosanganisira:

1. Zvinowedzerwa paPTFE: Polytetrafluoroethylene (PTFE) inogona kuderedza zvakanyanya kukweshana uye kupera kwePOM. Zvisinei, kuwanda kwazvo kunogona kuderedza simba remuchina wechinhu chacho, saka chiyero chakaenzana ndicho chinhu chakakosha.

Pamusoro pezvo, PTFE ndeyeboka rezvinhu zvinozivikanwa seper- uye polyfluoroalkyl substances (PFAS). Nekuda kwenjodzi dzinogona kuitika kuhutano nezvakatipoteredza dzakabatana nePFAS, European Chemicals Agency yakaburitsa chikumbiro kubva kunyika shanu dziri nhengo chekurambidza PFAS ine kanenge kabhoni imwe chete ine fluorinated carbon atomu - mamorekuru akasiyana anofungidzirwa kuva zviuru gumi, kusanganisira mafluoropolymer anozivikanwa. Nyika dziri nhengo dzakagadzirirwa kuvhota pakurambidzwa uku muna 2025. Kana chikumbiro cheEurope chikaramba chisina kuchinja, Kana chikumbiro chikaenderera mberi pasina shanduko, zvinogona kutungamira mukuchinja kukuru mukushandiswa kwemafluoropolymer akajairika sePTFE nePVDF, zvichitikurudzira kutsvaga dzimwe nzira dzakachengeteka uye mhinduro itsva.

2. Mafuta Asina Kugadzirwa: Molybdenum disulfide, boron nitride, nezvimwe zvinhu zvisina kuumbwa zvinogona kugadzira firimu rekufambisa pamusoro pePOM, zvichideredza kukweshana uye zvichivandudza kuramba kupfeka. Zvisinei, zvinhu izvi zvinowedzerwa zvinofanira kusarudzwa nokungwarira kudzivirira kukanganisa kugadzikana kwePOM.

Mhinduro Dzakanaka dzeKuramba Kupfeka Zvakanaka muPOM

Kune avo vari kutsvaga kuwedzera simba rekudzivirira kupfekwa kwePOM, SILIKE inopa huwandu hwakasiyana hwezvinhu zvinosimudzira nharaunda zvakagadzirirwa kuvandudza kugara kwenguva refu uye kugadzirisa zvinhu:

1. Silicone Masterbatch (Siloxane Masterbatch)LYSI-311: Iyi pelletized formula ine 50% ultra-high molecular weight siloxane polymer, yakapararira muPOM. Inovandudza hunhu hwekugadzirisa uye kunaka kwePOM, zvichiita kuti ive chinhu chinoshandiswa pakuvandudza mashandiro mumashandisirwo akasiyana-siyana.

 2. Kupfeka Kuramba Kuwedzera kune POM makemikari:Mhuri iri kukura yeSILIKE yezvinowedzerwa zvesilicone inowedzera zvakanyanya hunhu hwepamusoro hwezvinhu zve polyoxymethylene (POM).

Tinodada nekuzivisa mhuri yedu itsva yezvinowedzerwa zvesilicone,LYSI-701. Ichi chinowedzera silicone chakagadzirwa zvakananga kuti chiwedzere kuramba kupfeka kwemakemikari epolyoxymethylene (POM). Nechimiro chayo chakasiyana chepoly-siloxane, LYSI-701 inopararira zvakaenzana muPOM resin, zvichiita kuti ive mafuta pamusoro. Kufambira mberi uku kunoderedza zvakanyanya coefficient of friction (CoF), ukuwo kuchivandudzawo kuramba kukweshana uye kupwanya. Nekuda kweizvozvo, LYSI-701 inobatsira mukugara kwenguva refu kwezvinhu zvePOM, zvichiita kuti ive mhinduro inokosha kune akasiyana mashandisirwo.

Mabhenefiti Akakosha ekushandisa izvizvinowedzerwa zvesiliconezvinosanganisira:

1. Kuderedzwa Kwekukweshana: Chimiro chepolysiloxane chakasiyana chinoumba rukoko runozora paPOM, zvichideredza kukweshana uye zvinowedzera kusakara uye kuramba kutsvuka, ukuwo zvichichengetedza hunhu hwakanaka hwemakanika.

2. Hunhu Hwakanaka Hwakanatswa: Iyochinowedzera chesiloxaneinoita kuti pamusoro payo pave pakachena, zvichiita kuti zvigadzirwa zvapera zvionekwe zvakanaka.

3. Kugadziriswa Kwakagadziriswa: izviAnti-abrasion Masterbatchinovandudza kugona kuumbwa uye kuburitsa hunhu, zvichiwedzera kushanda zvakanaka kwekugadzira uye kunaka kwechigadzirwa.

4. Inochengetedza nharaunda uye yakachengeteka:zvinowedzerwa zvesiliconehaina chepfu, haina hwema, uye haina njodzi kune zvakatipoteredza, inosangana nezvinodiwa zveROHS uye zvinodiwa zveREACH zvisati zvanyoreswa. 

Kushandiswa kwezvinowedzera zvesiloxane muZvikamu zvePOM zveHigh-Performance

IzviZvinowedzerwa zvepurasitiki uye zvinogadzirisa polymerkunyanya LYSI-311 neLYSI-701, dzakanakira zvikamu zvePOM zvinoshanda zvakanyanya zvinoshandiswa mukugadzira, zvakaita se:

·Magiya, Mabheringi, uye Mabhandi Ekutakura Zvinhu: Uko kuramba kupfeka uye kugara kwenguva refu kunonyanya kukosha.

·Mota: Kusanganisira masisitimu ekusimudza mahwindo uye masensa ekufambisa makoramu.

·Zvinhu Zvinoshandiswa Nevatengi: Midziyo yemumba, midziyo yemitambo, nezvimwe zvinhu zvinoda kupfekwa zvakanyanya.

Nekushandisa izvi zvinowedzera zvakagadzirwa nesilicone muPOM formulations, vagadziri vePOM vanogona kuvandudza zvakanyanya hunhu hwemakanika uye hupenyu hwezvigadzirwa zvavo uku vachideredza kukweshana, kupfeka, uye kukanganisa nharaunda.
