Intshayelelo kwiPolyoxymethylene (POM)

I-Polyoxymethylene (POM), ekwaziwa ngokuba yi-acetal, i-polyacetal, okanye i-polyformaldehyde, yi-thermoplastic yobunjineli esebenza kakhulu eyaziwa ngeempawu zayo ezibalaseleyo zoomatshini kunye nozinzo olulinganayo. Isetyenziswa kakhulu kumashishini afuna ukuchaneka nokuqina, njengeemoto, izixhobo ze-elektroniki, izixhobo zonyango, kunye neempahla zabathengi.

IItekhnoloji yePOM eZinzileyo yamva nje: Amanqanaba amafutshane eFiber eQinisekisiweyo yeCellulose

Kutshanje iPolyplastics ityhile uluhlu olutsha lwee-DURACON® POM grades eziqiniswe ngee-fibers ze-cellulose ezimfutshane. Olu tshintsho lujongana nesidingo esikhulayo sezixhobo ezizinzileyo ngaphandle kokuphazamisa ukusebenza. Ngokungafaniyo ne-POM yendabuko egcwele iglasi, ezi grades ze-cellulose fiber-reinforced fiber-reinforced ziyandisa kakhulu i-flexural modulus ngelixa zigcina ukuqina okulula kunye nokuqina okuphezulu.

I-Cellulose, into engatyiwayo, esekwe kwi-bio, inegalelo ekuzinzeni kwendalo kwaye ibonwa njengezinto ezingenayo ikhabhoni ezifunxa i-CO2. Xa zidibene nentsimbi yekhabhoni (S45C), ezi zigaba zintsha ze-POM zibonisa i-dynamic friction coefficient ephantsi kunye nokuguguleka okunciphileyo, okwenza ukuba zilungele ukusetyenziswa okudinga ukuqina okuphezulu kunye neempawu ezibalaseleyo zokutyibilika.

Singayiphucula njani indlela i-POM ekwaziyo ukumelana nokuguguleka ngayo ngaphandle kokunciphisa ukusebenza okanye ukuqina kwayo?

Ukujongana nemingeni yokuNxila nokuQhaqha kwi-POM

Nangona kukho olu phuculo, izinto ezininzi zePOM zisajongene nemingeni emikhulu yokuguguleka nokungqubana, ingakumbi kwizicelo ezifunwa kakhulu njengeemoto, izixhobo ze-elektroniki kunye neempahla zabathengi.

Ezinye zezona zibalaseleyoiindlela eziqhelekileyo ezisetyenziswa ukuphucula ukumelana nokuguguleka kwe-POMziquka:

1. Izongezo ze-PTFE: I-Polytetrafluoroethylene (PTFE) inokunciphisa kakhulu ukungqubana kunye nokuguguleka kwe-POM. Nangona kunjalo, ubungakanani obugqithisileyo bunokunciphisa amandla oomatshini bezinto, ngoko ke idosi elinganisiweyo ibalulekile.

Ukongeza, i-PTFE ikwiqela lezinto ezaziwa ngokuba zii-per- kunye ne-polyfluoroalkyl substances (PFAS). Ngenxa yemingcipheko enokubakho yempilo kunye nokusingqongileyo enxulumene ne-PFAS, i-European Chemicals Agency ipapashe isindululo esivela kumazwe amahlanu angamalungu sokuthintela i-PFAS equlethe ubuncinane i-athomu enye yekhabhoni ene-fluorinated ngokupheleleyo-i-molecules eziqikelelwa kwi-10,000 ezahlukeneyo, kuquka ii-fluoropolymers ezidumileyo. Amazwe angamalungu amiselwe ukuvota kulo mthintelo ngo-2025. Ukuba isindululo saseYurophu asitshintshi, Ukuba isindululo siyaqhubeka ngaphandle kotshintsho, sinokukhokelela kutshintsho olukhulu ekusebenziseni ii-fluoropolymers eziqhelekileyo ezifana ne-PTFE kunye ne-PVDF, nto leyo esishukumisela ukuba sihlole ezinye iindlela ezikhuselekileyo kunye nezisombululo ezintsha.

2. Izithambisi ezingaPhiliyo: I-Molybdenum disulfide, i-boron nitride, kunye nezinye izinto ezingaphiliyo zinokwenza ifilimu yokudlulisa kumphezulu we-POM, nto leyo enciphisa ukungqubana nokuphucula ukumelana nokuguguleka. Nangona kunjalo, ezi zongezo kufuneka zikhethwe ngononophelo ukuze kuthintelwe ukuphazamisa uzinzo lobushushu be-POM.

Izisombululo Ezintsha Zokumelana Nokunxiba Okugqwesileyo kwi-POM

Kwabo bafuna ukuphucula ngakumbi ukumelana nokuguguleka kwePOM, iSILIKE inikezela ngoluhlu lwezongezo ezikhethekileyo ezinobuhlobo nokusingqongileyo ezenzelwe ukuphucula ukuqina kunye neempawu zokucubungula:

1. I-Silicone Masterbatch (iSiloxane Masterbatch)I-LYSI-311: Le fomyula efakwe iipellets iqulethe i-50% ye-molecular weight siloxane polymer ene-ultra-high molecular weight, esasazeke kwi-POM. Iphucula iipropati zokucubungula kunye nomgangatho womphezulu we-POM, nto leyo eyenza ukuba ibe sisongezelelo esisetyenziswa kakhulu ekuphuculeni ukusebenza kwizicelo ezahlukeneyo.

 2. Isongezelelo sokuxhathisa ukunxiba kwiikhompawundi zePOM:Usapho olukhulayo lwe-SILIKE lwezithako ze-silicone luphucula kakhulu iipropati zomphezulu weekhompawundi ze-polyoxymethylene (POM).

Siyazingca ngokwazisa usapho lwethu lwamva njeizongezo ze-silicone,I-LYSI-701. Esi songezo se-silicone sitsha senzelwe ngokukodwa ukuphucula ukumelana nokuguguleka kweekhompawundi ze-polyoxymethylene (POM). Ngesakhiwo sayo esikhethekileyo se-poly-siloxane, i-LYSI-701 isasazeka ngokulinganayo kuyo yonke i-POM resin, isenza ngokufanelekileyo umaleko wokuthambisa phezu komphezulu. Olu phuculo lunciphisa kakhulu i-coefficient of friction (CoF), ngelixa ikwaphucula ukuguguleka kunye nokumelana ne-mar. Ngenxa yoko, i-LYSI-701 inegalelo ekuqineni ngokubanzi kunye nobude bexesha lezinto ze-POM, okwenza ukuba ibe sisisombululo esixabisekileyo kwiindlela ezahlukeneyo zokusetyenziswa.

Iingenelo eziphambili zokusebenzisa eziizongezo ze-siliconeziquka:

1. Ukungqubana okuncitshisiweyo: Isakhiwo se-polysiloxane esahlukileyo senza umaleko wokuthambisa kwi-POM, sinciphisa ukungqubana kwaye sinyusa ukuguguleka kunye nokumelana nokubola, ngelixa sigcina iipropati ezintle zoomatshini.

2. Umgangatho oPhucukileyo woBuhle:isongezo se-siloxaneinika umphezulu ogudileyo, iphucula ukubonakala kweemveliso ezigqityiweyo.

3. Ukucutshungulwa Okulungiselelweyo: okuI-Masterbatch yokulwa nokukralaiphucula ukuguguleka kunye neempawu zokukhulula, iphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.

4. Ikhuselekile kwaye inobuhlobo nokusingqongileyo:izongezo ze-siliconeAyinatyhefu, ayinavumba, kwaye inobuhlobo nokusingqongileyo, ihlangabezana nemigangatho ye-ROHS kunye neemfuno ze-REACH zokubhalisa kwangaphambili. 

Ukusetyenziswa kwezongezo ze-siloxane kwiinxalenye ze-POM eziSebenzayo kakhulu

EziIzithako zePlastiki kunye nezilungisi zePolymeringakumbi i-LYSI-311 kunye ne-LYSI-701, zilungele izixhobo ze-POM ezisebenza kakuhle ezisetyenziswa kwizicelo zokuvelisa, ezinje:

·Iigiya, iibheringi, kunye neebhanti zokuhambisa: Apho ukumelana nokuguguleka kunye nokuqina kubaluleke kakhulu.

·Iimoto: Kubandakanya iinkqubo zokuphakamisa iifestile kunye neesensa zekholamu yokuqhuba.

·Izinto zabathengi: Izixhobo zasekhaya, izixhobo zemidlalo, kunye nezinye izinto ezifuna ukumelana nokuguguleka okukhulu.

Ngokufaka ezi zongezo ezisekelwe kwi-silicone kwiifomyula ze-POM, abavelisi be-POM banokuphucula kakhulu iipropati zoomatshini kunye nobude bexesha leemveliso zabo ngelixa benciphisa ukungqubana, ukuguguleka, kunye nempembelelo yokusingqongileyo.
