Polycarbonate (PC) ni imwe muri thermoplastics zikoreshwa cyane mu buhanga zikoreshwa mu mboni z’imodoka, ibikoresho by’ikoranabuhanga bikoreshwa n’abantu benshi, amaso, n’ibikoresho birinda indwara. Ingufu zayo zikomeye, imiterere yayo isobanutse neza, ndetse n’uburyo ihagaze neza bituma iba nziza cyane mu bikorwa bigoye. Ariko, ikibazo kizwi cyane cya mudasobwa ni uko ifite ubuso buke, bigatuma idakora neza kandi idasaza—cyane cyane iyo ikoraho kenshi cyangwa ikoraho nabi.
None se, ni gute abakora mudasobwa bashobora kongera uburambe bwayo mu isanzure batabangamiye imiterere yayo cyangwa imiterere yayo ya mekanike? Reka turebere hamwe ibisubizo bitandukanye byiza n'uburyo bwemewe n'inganda kugira ngo batsinde ibi bibazo.
Umuti: Huza uburyo bwo kunoza imikorere n'uburyo bwo guhindura imiterere y'ubutaka hamwe n'ikoranabuhanga rigezweho ryo kurinda.
1. Inyongera zishingiye kuri Silicone: Uburyo bwo kwisiga imbere
Gushyiramo inyongeramusaruro za silikoni zikora neza cyane, nka polydimethylsiloxane (PDMS) cyangwa siloxane-based masterbatches nka Dow MB50-001, Wacker GENIOPLAST, na SILIKE Silicone Masterbatch LYSI-413, mu nganda za polycarbonate (PC) bishobora kongera imikorere y'ibikoresho. Ukoresheje izi nyongeramusaruro ku kigero cya 1-3%, ushobora kugabanya neza coefficient of friction, ibi bikaba binongera ubushobozi bwo kudakora neza no kudashira.
Ibyiza by'ingenzi: Izi nyongeramusaruro za silikoni, nk'inyongeramusaruro zitunganya mudasobwa n'izihindura, ntizirinda gusa ubwiza bw'urumuri rwa mudasobwa ahubwo zinatuma ubushyuhe bw'ubuso burushaho kuba bwiza. Ibi bituma kwangirika kw'ubuso kugabanuka cyane mu gihe cyo gukoraho ibintu bikabije, amaherezo bigatuma ibicuruzwa biramba neza.
Inama y'ingirakamaro: Kugira ngo habeho imikorere myiza, ni ngombwa kugera ku gukwirakwira neza binyuze mu gusohora udupira tubiri, bifasha mu gukumira gutandukana kw'ibyiciro no kongera inyungu z'inyongera.
Chengdu SILIKE Technology Co., Ltd ni ikigo gikomeye mu Bushinwa gitanga serivisi zainyongera za silikoni ku pulasitiki yahinduwe. Iyi sosiyete itanga ibisubizo bishya bigamije kunoza imikorere n'imikorere y'ibikoresho bitandukanye bya pulasitiki. Kimwe mu bicuruzwa byabo by'indashyikirwa niSILIKE Silicone Masterbatch LYSI-413,Iyi poroteyine ikoze neza cyane irimo 25% bya siloxane polymer ifite uburemere bwa molekile bwinshi ikwirakwizwa muri polycarbonate (PC). Iyi poroteyine ishingiye kuri silicone ikora neza cyane kuri sisitemu za resin zijyanye na PC. Inoza imiterere yo gutunganya no kunoza ubwiza bw'ubuso binyuze mu kongera ubushobozi bwo gutembera kwa resin, yorohereza kuzuza no kurekura ibumba, igabanya torque ya extruder, igabanya coefficient of friction, kandi itanga ubushobozi bwo kurwanya mar na abrasion. Byongeye kandi, iyi masterbatch ishingiye kuri siloxane ikora nk'inyongera irwanya scratch, bigatuma iba igisubizo cyiza cyo kongera ubushobozi bwo kurwanya scratch ku bicuruzwa bya PC no kunoza imikorere yabyo muri rusange no kuramba.
2. Irangi rikomeye rishobora kuvurwa n'imirasire ya UV rikoresheje Nanotechnology
Shyiraho irangi rikomeye rishingiye kuri siloxane cyangwa hybrid organic-inorganic coatings (urugero, Momentive SilFORT AS4700 cyangwa PPG's DuraShield). Iri rangi rigira ubukana bw'ikaramu kugeza kuri 7H-9H, rirushaho kunoza cyane ubushobozi bwo kwirinda gushwara.
Shyiramo irangi rishobora kuvurwa n'imirasire y'izuba hamwe n'uduce duto (urugero: silica cyangwa zirconia) kugira ngo wongere imbaraga zo kurwanya kwangirika kw'imirasire.
Akamaro: Itanga uruzitiro rurinda iminkanyari, imiti, n'iyangirika ry'imirasire ya UV, ikaba nziza cyane mu gukoresha amatara n'imodoka.
Gukoresha: Koresha irangi ryo mu mazi, irangi ryo gutera imiti, cyangwa irangi ryo gutwikira amazi kugira ngo ubone ubugari bungana (5-10 µm).
3. Gukomeza Nanocomposite
Shyiramo ibikoresho bito nka nanosilica, alumina, cyangwa graphene oxide (uburemere bwa 0.5-2%) kuri PC matrix. Ibi byongera ubukana bw'ubuso kandi bikongera ubushobozi bwo kwangirika bitagize ingaruka zikomeye ku mucyo niba ingano y'uduce turi munsi ya 40 nm.
Urugero: Ubushakashatsi bwerekana ko 1% ya nanosilica muri PC ishobora kongera ubudahangarwa bwa Taber ku kigero cya 20-30%.
Inama: Koresha ibikoresho bihuza ibintu (urugero: ibikoresho bihuza ibintu bya silane) kugira ngo wizere ko bikwirakwira neza kandi wirinde ko ibintu biterana.
4. Imvange za PC kugira ngo zigire imikorere iringaniye
Vanga mudasobwa na PMMA (10-20%) kugira ngo wongere ubukana bw'ubuso cyangwa PBT kugira ngo wongere ubukana n'ubudasaza. Ibi bivanga uburyo bwo kuringaniza ubukana bw'imikurire n'ubukana bw'imbaraga za mudasobwa.
Urugero: Uruvange rwa PC/PMMA rufite 15% bya PMMA rushobora kongera ubukana bw'ubuso mu gihe rugumana ubuziranenge ku bikoresho byo kwerekana.
Icyitonderwa: Hindura uburyo bwo guhuza ibikoresho kugira ngo wirinde ko ubushyuhe bwa mudasobwa buhagarara nabi cyangwa bugakomera.
5. Ubuhanga buhanitse bwo guhindura ubuso
Uburyo bwo kuvura plasma: Shyira plasma-enhanced chemical vapor deposition (PECVD) kugira ngo ushyiremo utwenda duto kandi dukomeye nka silicon oxynitride (SiOxNy) ku buso bwa mudasobwa. Ibi byongera ubushobozi bwo kudashwara no kwangirika.
Gushushanya hakoreshejwe laser: Gukora imiterere mito cyangwa mito ku buso bwa mudasobwa kugira ngo bigabanye aho ikoraho no gukwirakwiza imikurire, binoze ubwiza.
Akamaro: Gushushanya imiterere y'inyuma bishobora kugabanya gushwanyagurika ku kigero cya 40% mu buryo bworoshye cyane.
6. Inyongeramusaruro zo guhuza ibikorwa
Huza inyongera za silikoni n'izindi nyongera zikora nka PTFE (polytetrafluoroethylene) micropowders (0.5-1%) kugira ngo ubone ingaruka nziza. PTFE yongera ubushyuhe, mu gihe silikoni yongera ubukana bw'ingufu.
Urugero: Uruvange rwa 2% bya silicone masterbatch na 0.5% bya PTFE bishobora kugabanya igipimo cyo kwangirika ho 25% mu gukoresha sliding.
7. Imiterere myiza yo gutunganya:
Koresha imvange ikomeye kugira ngo ukwirakwize inyongeramusaruro n'ibizitunga mu buryo bumwe. Komeza ubushyuhe bwo gutunganya mudasobwa (260-310°C) kugira ngo wirinde kwangirika.
Koresha uburyo bwo gushushanya neza (urugero, gushushanya hakoreshejwe inshinge zikozwe mu buryo bwa polished) kugira ngo ugabanye inenge zo hejuru zishobora gutera gushwanyagurika.
Ibice byabumbwe na Anneal kuri 120-130°C kugira ngo bigabanye imihangayiko y'imbere, binoze imikorere y'igihe kirekire yo kwangirika.
Isuzuma ry'udushya: Kwivura no gusiga DLC biri kwiyongera
Ikoranabuhanga riri kuzamuka nko kwisiga irangi ryikora (rishingiye kuri shimi ya polyurethane cyangwa siloxane) n'irangi rya karuboni rimeze nka diyama (DLC) ritanga ibisubizo bihamye mu gihe kizaza ku bikoresho bya mudasobwa biramba cyane kandi bikozweho cyane. Nubwo bikihendutse ku bicuruzwa byinshi ku isoko, iri koranabuhanga ritanga icyizere mu bikoresho by'ikoranabuhanga bigezweho, imodoka, n'iby'indege.
Uburyo busabwa bwo gukora neza mu buhanga bwa Thermoplastics
Ku bakora bashaka igisubizo gifatika kandi gishobora kwaguka kugira ngo bongere uburambe bw'ubuso bwa mudasobwa, turabagira inama:
1)Inyongera ya 2% ya UHMW ya Silicone yo gusiga imbere mu mazutu
2) Udupira twa UV dushingiye kuri Siloxane + 1% Nano Silika yo gukomera kw'ubuso
3) Micro-Texturing ukoresheje Laser Molding kugira ngo uhishe iminkanyari
Ubu buryo bugizwe n'ibice bitatu butanga uburinganire mu bijyanye no gukoresha neza ikiguzi, guhuza uburyo bwo gutunganya ibicuruzwa, n'imikorere yabyo, bigatuma biba byiza ku bicuruzwa byambarwa buri munsi kandi bisaba ubwiza burambye.
Byagaragaye ko ari inganda
Nk’uko raporo ya MarketsandMarkets yo mu 2024 ibigaragaza, isoko ry’isi yose ry’amabara akomeye riteganijwe kurenga miliyari 1.3 z’amadolari mu 2027, bitewe n’ubwiyongere bw’ibiciro bya pulasitiki zidashwanyagurika mu bikoresho by’imodoka, ibikoresho bigendanwa, n’indorerwamo z’amatara. Ibyuma bya formulaire n’ibivangavanze bihuza inyongera zikoreshwa mu buryo bwinshi n’ibinyabutabire bito bito bifite umwanya mwiza wo kuyobora igisekuru gitaha cy’ibicuruzwa biramba bishingiye kuri mudasobwa.
