Intangiriro kuri Polyoxymethylene (POM)

Polyoxymethylene (POM), izwi kandi nka acetal, polyacetal, cyangwa polyformaldehyde, ni thermoplastic y’ubuhanga ikora neza izwiho imiterere yayo idasanzwe ya mekanike no kudahindagurika mu buryo buhanitse. Ikoreshwa cyane mu nganda zisaba ubuziranenge no kuramba, nko mu modoka, mu by’ikoranabuhanga, mu by’ubuvuzi, no mu bicuruzwa bikoreshwa n’abantu.

ItsindaIkoranabuhanga rigezweho rya POM rirambye: Ingano ngufi ya selulosi ikomeje gukomezwa

Polyplastics iherutse gushyira ahagaragara ubwoko bushya bwa DURACON® POM grades bukomejwe n'imigozi migufi ya cellulose. Ubu buryo bushya bukemura ikibazo cy'uko ibikoresho biramba bidahungabanyije imikorere. Bitandukanye na POM isanzwe yuzuye ikirahure, iyi migozi migufi ya cellulose-reinforced fibre-reinforced fibre-reinforced fibre-boosting yongera cyane flexural modulus mugihe ikomeza kuba yoroheje kandi ikomeye.

Selulosi, ibikoresho bitaribwa, bishingiye ku binyabuzima, bigira uruhare mu kubungabunga ibidukikije kandi bizwi nk'ibikoresho bidafite karuboni bikuramo CO2. Iyo bihujwe n'icyuma cya karuboni (S45C), ibi byiciro bishya bya POM bigaragaza ubushobozi bwo kugabanya imbaraga no kwangirika, bigatuma biba byiza mu bikorwa bikomeye bisaba gukomera cyane no kugenda neza.

Ni gute twakongera ubushobozi bwa POM bwo kudashira tudatesheje agaciro imikorere cyangwa uburyo burambye?

Gukemura ibibazo byo kwangirika no guhindagurika kw'imyambaro muri POM

Nubwo hari iterambere rikabije, ibikoresho byinshi bya POM biracyafite imbogamizi zikomeye zo kwangirika no guhindagurika kw'ibikoresho, cyane cyane mu bikorwa bikenerwa cyane nko mu modoka, ibikoresho by'ikoranabuhanga, n'ibicuruzwa bikoreshwa mu buryo busanzwe.

Bimwe mu byo cyaneuburyo busanzwe bukoreshwa mu kongera ubushobozi bwo kudashira bwa POMharimo:

1. Inyongera za PTFE: Polytetrafluoroethylene (PTFE) ishobora kugabanya cyane kwangirika no kwangirika kwa POM. Ariko, ingano irenze urugero ishobora kugabanya imbaraga za mekanike z'ibikoresho, bityo ingano iringaniye ni ingenzi.

Byongeye kandi, PTFE iri mu itsinda ry'ibintu bizwi nka per- na polyfluoroalkyl substances (PFAS). Bitewe n'ingaruka zishobora guterwa n'ubuzima n'ibidukikije zijyanye na PFAS, Ikigo cy'Uburayi gishinzwe imiti cyasohoye icyifuzo cyavuye mu bihugu bitanu bigize umuryango cyo guhagarika PFAS irimo nibura atome imwe ya karubone yuzuye fluorine -- igizwe na molekile zigera ku 10.000 zitandukanye, harimo na fluoropolymers zikunzwe cyane. Ibihugu bigize umuryango biteganijwe gutora iri tegeko muri 2025. Niba icyifuzo cy'Uburayi kidahindutse, niba icyifuzo gikomeje nta mpinduka, gishobora gutera impinduka zikomeye mu ikoreshwa rya fluoropolymers zisanzwe nka PTFE na PVDF, bikadushishikariza gushaka ubundi buryo bwizewe n'ibisubizo bishya.

2. Amavuta atagira umwimerere: Molybdenum disulfide, boron nitride, n'ibindi bikoresho bisa nabyo bishobora gukora filime yo kohereza ku buso bwa POM, bigagabanya kwangirika no kongera ubushobozi bwo kwangirika. Ariko, ibi birungo bigomba gutoranywa neza kugira ngo hirindwe ko ubushyuhe bwa POM bwangirika.

Ibisubizo bishya byo kurwanya kwambara nabi cyane muri POM

Ku bashaka kongera ubushobozi bwo kudashira kwa POM, SILIKE itanga ubwoko butandukanye bw'inyongera zihariye zigamije kunoza ibidukikije kugira ngo zirusheho kuramba no gutunganya ibintu:

1. Silicone Masterbatch (Siloxane Masterbatch)LYSI-311: Iyi formula irimo pellet irimo 50% ya siloxane polymer ifite uburemere bwa molekile bwinshi, ikwirakwizwa muri POM. Yongera imiterere yo gutunganya no kunoza ubwiza bwa POM, bigatuma iba inyongeramusaruro ikoreshwa mu kunoza imikorere mu bikorwa bitandukanye.

 2. Inyongeramusaruro yo kurwanya kwambara ku bintu bya POM:Umuryango wa SILIKE w’inyongera za silikoni wongera cyane imiterere y’ubuso bw’ibinyabutabire bya polyoxymethylene (POM).

Twishimiye kumenyekanisha umuryango wacu mushya w’abakiri bato mu muryango wainyongeramusaruro za silikoni,LYSI-701. Iyi nyongeramusaruro nshya ya silikoni yagenewe by'umwihariko kongera ubushobozi bwo kudashira bw'ibinyabutabire bya polyoxymethylene (POM). Hamwe n'imiterere yayo yihariye ya poly-siloxane, LYSI-701 ikwirakwira neza muri resin ya POM, bigatuma ikora neza urwego rwo gusiga amavuta ku buso. Iri terambere rigabanya cyane coefficient of friction (CoF), ndetse rinanongera uburyo bwo gushwanyagurika no kudashwanyagurika. Kubera iyo mpamvu, LYSI-701 igira uruhare mu kuramba no kuramba kw'ibikoresho bya POM, bigatuma biba igisubizo cy'ingirakamaro ku bikorwa bitandukanye.

Ibyiza by'ingenzi byo gukoresha ibiinyongeramusaruro za silikoniharimo:

1. Kugabanya Gucikagurika: Imiterere yihariye ya polysiloxane ikora urwego rwo gusiga amavuta kuri POM, igabanya gucikagurika no kongera kwangirika no kudashira, mu gihe igumana imiterere myiza ya mekanike.

2. Ubwiza bw'ubwiza burushijeho kuba bwiza:inyongeramusaruro ya siloxanebitanga irangi ryoroshye, bikongera ubwiza bw'ibicuruzwa byarangiye.

3. Gutunganya neza: ibiMasterbatch yo kurwanya kwangirikakunoza ubushobozi bwo gushonga no kurekura, bikongera imikorere myiza mu nganda no mu bwiza bw'ibicuruzwa.

4. Irinda ibidukikije kandi ifite umutekano:inyongeramusaruro za silikonintabwo ari uburozi, nta mpumuro, kandi ntirinda ibidukikije, yujuje ibisabwa na ROHS na REACH mbere yo kwiyandikisha. 

Imikoreshereze y'inyongera za siloxane mu bice bya POM bifite imikorere myiza

IbiInyongeramusaruro za Plastiki n'imashini zihindura polymercyane cyane LYSI-311 na LYSI-701, ni byiza cyane ku bice bya POM bikora neza cyane bikoreshwa mu nganda, nka:

·Ibyuma, amabeteri, n'imikandara yo gutwara ibintu: Aho imbaraga zo kudashira no kuramba ari byo by'ingenzi.

·Imodoka: Harimo sisitemu zo guterura amadirishya n'ibikoresho byo kugenzura inkingi z'ubuyobozi.

·Ibikoresho by'Abaguzi: Ibikoresho byo mu rugo, ibikoresho bya siporo, n'ibindi bikoresho bisaba kwangirika cyane.

Mu gushyira izi nyongeramusaruro zishingiye kuri silikoni mu miterere ya POM, abakora POM bashobora kunoza cyane imiterere ya mekanike n'igihe kirekire cy'ibicuruzwa byabo mu gihe bigabanya kwangirika, kwangirika, n'ingaruka ku bidukikije.
