Intshayelelo yePolyoxymethylene (POM)

I-Polyoxymethylene (i-POM), ekwabizwa ngokuba yi-acetal, i-polyacetal, okanye i-polyformaldehyde, bubunjineli bokusebenza okuphezulu kwe-thermoplastic eyaziwayo ngeempawu zayo ezikhethekileyo kunye nozinzo lwe-dimensional. Isetyenziswa kakhulu kumashishini afuna ukuchaneka kunye nokuqina, okufana neemoto, izinto zombane, izixhobo zonyango, kunye nempahla yabathengi.

IIteknoloji yePOM yamva nje eZinzileyo: IFayibha emfutshane yeCellulose eQiniswayo

I-Polyplastics isandul 'ukuveza uluhlu olutsha lwamabakala e-DURACON® POM aqiniswe ngeefiber ezimfutshane ze-cellulose. Olu lutsha lujongana nesidingo esikhulayo sezinto ezizinzileyo ngaphandle kokubeka esichengeni ukusebenza. Ngokungafaniyo ne-POM yeglasi egcwele iglasi, ezi zibakala zifutshane ze-cellulose fibre-reinforced grade kakhulu zonyusa imodulus eguquguqukayo ngelixa zigcina ukukhanya kunye nokuqina okuphezulu.

I-Cellulose, into engenakudliwayo, i-bio-based material, igalelo ekuzinzeni kwendalo kwaye ibonwa njenge-carbon-negative material ethatha i-CO2. Xa zidityaniswe nentsimbi yekhabhoni (i-S45C), la mabanga matsha e-POM abonisa i-coefficient ephantsi yokhuhlane kunye nokunxitywa okuncitshisiweyo, okubenza balungele izicelo ezifuna ukuba ngqongqo okuphezulu kunye neempawu ezibalaseleyo zokutyibilika.

Singayiphucula njani inkcaso yokunxiba yePOM ngaphandle kokuncama ukusebenza okanye ukuzinza?

Ukujongana nemingeni yokuNxitywa kunye neFriction kwi-POM

Ngaphandle kolu phuculo, izixhobo ezininzi zePOM zisajongene nemiceli mngeni ebalulekileyo ngokunxiba kunye nokungqubana, ngakumbi kwizicelo ezifunwa kakhulu njengemoto, i-elektroniki, kunye nempahla yabathengi.

Ezinye zezona zininziiindlela eziqhelekileyo ezisetyenziselwa ukunyusa ukuxhathisa ukunxiba kwe-POMziquka:

1. Izongezo ze-PTFE: I-Polytetrafluoroethylene (PTFE) inokunciphisa kakhulu ukungqubuzana kunye nokugqoka kwi-POM. Nangona kunjalo, izixa ezigqithisileyo zinokuwenza buthathaka amandla omatshini, ngoko ke idosi elinganayo ingundoqo.

Ukongeza, i-PTFE yeyeqela lezinto ezaziwa njenge-per- kunye ne-polyfluoroalkyl substances (PFAS). Ngenxa yobungozi obunokubakho kwezempilo kunye nokusingqongileyo okunxulunyaniswa nePFAS, i-Arhente yeMichiza yaseYurophu ipapashe isindululo esisuka kumazwe amahlanu angamalungu ukuba ithintele iPFAS equlethe ubuncinci iathomu yekhabhoni egcwele ngokupheleleyo-kuqikelelwa ukuba iimolekyuli ezahlukeneyo ze-10,000, kubandakanya ii-fluoropolymers ezidumileyo. Amazwe angamalungu amiselwe ukuvota kwesi sithintelo kwi-2025. Ukuba isiphakamiso saseYurophu sihlala singatshintshi, Ngaba isiphakamiso siqhubeke ngaphandle kotshintsho, sinokukhokelela ekutshintsheni okuphawulekayo ekusebenziseni i-fluoropolymers eqhelekileyo njenge-PTFE kunye ne-PVDF, esishukumisela ukuba sihlolisise ezinye iindlela ezikhuselekileyo kunye nezisombululo ezintsha.

2. I-Inorganic Lubricants: I-Molybdenum disulfide, i-boron nitride, kunye nezinto ezifanayo ze-inorganic zingenza ifilimu yokudlulisa kwindawo ye-POM, ukunciphisa ukungqubuzana kunye nokuphucula ukuxhatshazwa kokugqoka. Nangona kunjalo, ezi zongezo kufuneka zikhethwe ngononophelo ukuphepha ukubeka esichengeni ukuzinza kwe-POM ye-thermal.

Izisombululo eziNtsha zoKuxhathisa okuPhezulu kwi-POM

Kwabo bafuna ukomeleza ngakumbi ukunganyangeki kokunxiba kwePOM, i-SILIKE ibonelela ngoluhlu lwezongezo ezikhethekileyo ze-eco-Friendly ezenzelwe ukuphucula ukuqina kunye nokusetyenzwa kweepropathi:

1. ISilicone Masterbatch (Siloxane Masterbatch)I-LYSI-311: Olu qulunqo lwe-pelletized luqukethe i-50% ye-ultra-high molecular weight siloxane polymer, ihlakazwe kwi-POM. Iphucula iipropathi zokusetyenzwa kunye nomgangatho womphezulu we-POM, iyenza ibe yinto eyongezelelweyo yokuphucula ukusebenza kwizicelo ezahlukeneyo.

 2. Nxiba i-Resistance Additive ye-POM compounds:Usapho luka-SILIKE olwandayo lwezongezo ze-silicone zongeza kakhulu iipropathi zomphezulu we-polyoxymethylene (POM) iikhompawundi.

Siyazingca ukwazisa ulongezo lwethu lwamva nje kusapho lweizongezo ze-silicone,I-LYSI-701. Olu longezelelo lwe-silicone oluhlaziyiweyo lwenzelwe ngokukodwa ukunyusa ukunyanzeliswa kwe-polyoxymethylene (POM) iikhompawundi. Ngesakhiwo sayo esikhethekileyo se-poly-siloxane, i-LYSI-701 ihlakazeka ngokulinganayo kuyo yonke i-POM resin, ngokufanelekileyo yenza i-lubricating layer on the surface. Oku kuqhubela phambili kunciphisa kakhulu i-coefficient of friction (CoF), ngelixa ikwaphucula i-abrasion kunye nokumelana ne-mar. Ngenxa yoko, i-LYSI-701 inegalelo ekuhlala kuyo yonke into kunye nobomi obude bezinto ze-POM, okwenza kube sisisombululo esibalulekileyo kwizicelo ezahlukeneyo.

IiNzuzo eziPhambili zokusebenzisa eziizongezo ze-siliconeziquka:

1. I-Friction eNcitshisiweyo: Ulwakhiwo olulodwa lwe-polysiloxane lwenza umaleko wokuthambisa kwi-POM, ukuthoba ukungqubana kunye nokunyusa ukunxiba kunye nokumelana ne-mar, ngelixa ugcina iimpawu ezibalaseleyo zoomatshini.

2. UPhucuko loMgangatho wobuhle: Isiloxane additiveinika umphezulu ogudileyo, uphucula umtsalane obonakalayo weemveliso ezigqityiweyo.

3. ULungiselelo oluLungileyo: okuAnti-abrasion Masterbatchiphucula ukubunjwa kunye nokukhulula iipropati, iphucula ukusebenza kakuhle kokwenziwa kunye nomgangatho wemveliso.

4. I-Eco-friendly kwaye ikhuselekile:izongezo ze-siliconeayinayo ityhefu, ayinavumba, kwaye ayinabungozi kokusingqongileyo, iyahlangabezana nemigangatho ye-ROHS kunye ne-REACH iimfuno zobhaliso lwangaphambili. 

Ukusetyenziswa kwezongezo ze-siloxane kwi-High-Performance POM Components

EziIzongezo zePlastiki kunye nezilungisi zePolymerngakumbi i-LYSI-311 kunye ne-LYSI-701, zifanelekile kumacandelo e-POM asebenza ngokuphezulu asetyenziswa kwizicelo zokuvelisa, ezinje:

·Iigiya, iiBearings, kunye ne-Conveyor Belts: Apho ukunxitywa kunye nokuqina kubaluleke kakhulu.

·I-Automotive: Kubandakanya iinkqubo zokuphakamisa iifestile kunye ne-steering column sensors.

·Iimpahla zabathengi: Izixhobo zasekhaya, izixhobo zemidlalo, kunye nezinye izinto ezifuna ukuxhathisa ukunxiba.

Ngokubandakanya ezi zongezo ezisekelwe kwi-silicone kwiifom ze-POM, abavelisi be-POM banokuphucula kakhulu iimpawu zomatshini kunye nexesha elide leemveliso zabo ngelixa benciphisa ukungqubuzana, ukunxiba kunye nefuthe lokusingqongileyo.
