Selelekela ho Polyoxymethylene (POM)

Polyoxymethylene (POM), e tsejoang hape e le acetal, polyacetal, kapa polyformaldehyde, ke thermoplastic ea boenjiniere e sebetsang hantle e tsebahalang ka thepa ea eona e ikhethang ea mechini le botsitso ba litekanyo. E sebelisoa haholo liindastering tse hlokang ho nepahala le ho tšoarella, joalo ka likoloi, lisebelisoa tsa elektroniki, lisebelisoa tsa bongaka le thepa ea bareki.

TheTheknoloji ea morao-rao ea POM e tsitsitseng: Mekhahlelo e Khutšoanyane ea Cellulose Fiber e Matlafalitsoeng

Polyplastics e sa tsoa senola mefuta e mecha ea limaraka tsa DURACON® POM tse matlafalitsoeng ka likhoele tse khutšoane tsa cellulose. Tlhahiso ena e sebetsana le tlhoko e ntseng e hola ea thepa e tšoarellang ntle le ho beha ts'ebetso kotsing. Ho fapana le POM ea setso e tletseng khalase, limaraka tsena tse khutšoane tsa fiber ea cellulose tse matlafalitsoeng li eketsa modulus ea flexural haholo ha li ntse li boloka boima le ho tiea ho hoholo.

Cellulose, e leng thepa e sa jeoeng, e thehiloeng linthong tse phelang, e kenya letsoho ho tsitseng tikoloho mme e tsejoa e le thepa e se nang khabone e monyang CO2. Ha e kopantsoe le tšepe ea khabone (S45C), limaraka tsena tse ncha tsa POM li bontša coefficient e tlase ea khohlano e matla le ho senyeha ho fokotsehileng, e leng se etsang hore li be ntle bakeng sa lits'ebetso tse hlokang ho tiea ho hoholo le thepa e ntle ea ho thella.

Re ka ntlafatsa ho hanyetsa ho tsofala ha POM joang ntle le ho senya ts'ebetso kapa botsitso?

Ho Sebetsana le Mathata a ho Tshwara le ho Kgohlana ho POM

Ho sa tsotellehe tsoelo-pele ena, thepa e mengata ea POM e ntse e tobana le liphephetso tse kholo tsa ho tsofala le khohlano, haholo-holo lits'ebetsong tse batloang haholo joalo ka likoloi, lisebelisoa tsa elektroniki le thepa ea bareki.

Tse ling tsa tse ngata ka ho fetisisamekhoa e tloaelehileng e sebelisoang ho ntlafatsa khanyetso ea ho tsofala ha POMkenyeletsa:

1. Lisebelisoa tsa PTFE: Polytetrafluoroethylene (PTFE) e ka fokotsa khohlano le ho tsofala ha POM haholo. Leha ho le jwalo, bongata bo feteletseng bo ka fokodisa matla a mechini a thepa, kahoo tekanyo e leka-lekaneng ke ya bohlokwa.

Ho phaella moo, PTFE ke ya sehlopha sa dintho tse tsejwang e le dintho tsa per- le polyfluoroalkyl (PFAS). Ka lebaka la dikotsi tse ka bang teng tsa bophelo bo botle le tikoloho tse amanang le PFAS, European Chemical Agency e phatlaladitse tlhahiso e tswang dinaheng tse hlano tse leng ditho ho thibela PFAS e nang le bonyane athomo e le nngwe ya carbon e nang le fluorine ka botlalo - e leng dimolek'hule tse fapaneng tse hakanyetswang ho 10,000, ho kenyeletswa le di-fluoropolymer tse tsebahalang. Dinaha tse leng ditho di ikemiseditse ho vouta thibelong ena ka 2025. Haeba tlhahiso ya Yuropa e dula e sa fetohe, Haeba tlhahiso e ka tswela pele ntle le diphetoho, e ka lebisa diphetohong tse kgolo tshebedisong ya di-fluoropolymer tse tlwaelehileng jwalo ka PTFE le PVDF, e leng se re susumeletsang ho batlisisa mekgwa e meng e bolokehileng le ditharollo tse ntjha.

2. Litlolo tse sa pheleng: Molybdenum disulfide, boron nitride, le thepa e tšoanang e sa pheleng e ka etsa filimi ea phetisetso holim'a POM, e fokotsa khohlano le ho ntlafatsa ho hanyetsa ho tsofala. Leha ho le joalo, lintho tsena tse eketsang li tlameha ho khethoa ka hloko ho qoba ho beha botsitso ba mocheso ba POM kotsing.

Litharollo tse Ncha bakeng sa Khanyetso e Phahameng ea ho Aparela ho POM

Bakeng sa ba batlang ho ntlafatsa ho hanyetsa ho tsofala ha POM, SILIKE e fana ka mefuta e fapaneng ea litlatsetso tse ikhethileng tse mosa tikolohong tse etselitsoeng ho ntlafatsa ho tšoarella le thepa ea ho sebetsana le tsona:

1. Silicone Masterbatch (Siloxane Masterbatch)LYSI-311: Sebopeho sena se nang le pellet se na le polymer ea siloxane ea boima ba limolek'hule ea 50% e phahameng haholo, e hasantsoeng ka POM. E ntlafatsa thepa ea ts'ebetso le boleng ba bokaholimo ba POM, e leng se etsang hore e be sejo se ka sebelisoang haholo bakeng sa ho ntlafatsa ts'ebetso lits'ebetsong tse fapaneng.

 2. Sejo se eketsang ho hanyetsa ho apara bakeng sa metsoako ea POM:Lelapa le ntseng le hola la SILIKE la li-additives tsa silicone le ntlafatsa haholo thepa ea bokaholimo ba metsoako ea polyoxymethylene (POM).

Re motlotlo ho hlahisa setho sa rona sa morao-rao se eketsehileng lelapeng lalintho tse eketsang silicone,LYSI-701. Sesebelisoa sena se secha sa silicone se etselitsoe ka ho khetheha ho ntlafatsa khanyetso ea ho tsofala ha metsoako ea polyoxymethylene (POM). Ka sebopeho sa eona se ikhethang sa poly-siloxane, LYSI-701 e hasana ka ho lekana ho pholletsa le resin ea POM, e etsa lera le tlotsang holim'a metsi ka katleho. Tsoelo-pele ena e fokotsa haholo coefficient of friction (CoF), ha ka nako e ts'oanang e ntlafatsa khanyetso ea ho khohlela le ho bola. Ka lebaka leo, LYSI-701 e thusa ho tšoarella ka kakaretso le ho phela nako e telele ha thepa ea POM, e leng se etsang hore e be tharollo ea bohlokoa bakeng sa lits'ebetso tse fapaneng.

Melemo ea Bohlokoa ea ho sebelisa tsenalintho tse eketsang siliconekenyeletsa:

1. Khohlano e Fokolitsoeng: Sebopeho se ikhethang sa polysiloxane se etsa lera le tlotsang holim'a POM, se fokotsa khohlano le ho matlafatsa ho tsofala le ho hanyetsa ho bola, ha ka nako e ts'oanang se boloka thepa e ntle ea mechini.

2. Boleng bo Ntlafetseng ba Botle:setlolo sa siloxanee fana ka qetello e boreleli ea bokaholimo, e ntlafatsang ponahalo ea lihlahisoa tse felileng.

3. Ts'ebetso e Ntlafalitsoeng: enaMasterbatch ea ho loantša ho khohlelae ntlafatsa ho boptjoa le ho lokolloa ha thepa, e ntlafatsa bokgoni ba tlhahiso le boleng ba sehlahiswa.

4. E bolokehile ebile e bolokehile:lintho tse eketsang siliconeHa e na chefo, ha e nkge, ebile e mosa tikolohong, e fihlela maemo a ROHS le litlhoko tsa REACH tsa pele ho ngodiso. 

Tšebeliso ea li-additives tsa siloxane ho Likarolo tsa POM tse nang le Ts'ebetso e Phahameng

TsenaLisebelisoa tsa polasetiki le li-polymer modifiershaholo-holo LYSI-311 le LYSI-701, li loketse likarolo tsa POM tse sebetsang hantle tse sebelisoang lits'ebetsong tsa tlhahiso, tse kang:

·Li-gear, Li-bearings, le Mabanta a Conveyor: Moo ho hanyetsa ho tsofala le ho tšoarella e leng habohlokoa ka ho fetisisa.
