Polycarbonate (PC) ndeimwe yeanonyanya kushandiswa einjiniya thermoplastics inoshandiswa mumalenzi emotokari, zvemagetsi zvevatengi, zvipfeko zvemaziso, uye giya rekudzivirira. Kusimba kwayo kwepamusoro, kujeka kwemaziso, uye kugadzikana kwedimensional inoita kuti ive yakanaka kune inoda maapplication. Nekudaro, iyo inozivikanwa dhizaini yePC ndeye kuderera kwayo kwepasi kuomarara, izvo zvinotungamira kune isina kunaka kukwenya uye kupfeka kuramba-kunyanya pasi pekugara uchisangana kana abrasive mamiriro.
Saka, vagadziri vanogona sei kuwedzera kusimba kwepamusoro kwePC pasina kukanganisa kujeka kwayo kana michina yemagetsi? Ngationgororei huwandu hwemhinduro dzinoshanda uye nzira dzakasimbiswa neindasitiri yekukunda matambudziko aya.
Solution: Sanganisa magadzirirwo ekusimudzira uye pamusoro pezvivakwa zvinogadziridzwa nepamusoro pekudzivirira matekinoroji.
1. Silicone-Based Additives: Internal lubricity
Kubatanidza yakakwirira-inoshanda silicone additives, senge polydimethylsiloxane (PDMS) kana siloxane-based masterbatches seDow MB50-001, Wacker GENIOPLAST, uye SILIKE Silicone Masterbatch LYSI-413, mune polycarbonate (PC) maumbirwo anogona kuwedzera zvakanyanya kuita kwechinhu. Nekushandisa izvi zvinowedzera pamwero wekurodha we1-3%, unogona kudzikisa zvinobudirira coefficient yekukwesha, iyo inovandudza zvese scratch kuramba uye kupfeka kusimba.
Mabhenefiti Akakosha: Aya masilicone ekuwedzera, sePC kugadzirisa ekuwedzera uye modhifita, haango chengetedza kujeka kwePC asi zvakare anowedzera lubricity. Izvi zvinoguma nekudzikiswa kunoshamisa kwekukuvadzwa kwepasi panguva yekubata abrasive, zvinozotungamira kune yakavandudzwa yehupenyu hwechigadzirwa.
Zano Rinoshanda: Kuti uve nechokwadi chekuita kwakaringana, zvakakosha kuti uwane kupararira kwakakodzera kuburikidza nemapatya-screw extrusion, iyo inobatsira kudzivirira kupatsanurwa kwechikamu uye inowedzera mabhenefiti ekuwedzera.
Chengdu SILIKE Technology Co., Ltd inotungamira yekuChina mutengesi wesilicone additives for modified plastics. Iyo kambani inopa zvigadziriso zvakagadzirirwa kusimudzira mashandiro uye kushanda kwezvinhu zvakasiyana-siyana zvepurasitiki. Imwe yezvigadzirwa zvavo zvakanakisa ndeyeSILIKE Silicone Masterbatch LYSI-413,inonyatsoshanda pelletized kuumbwa iyo ine 25% yekupedzisira-yakakwirira molecular uremu siloxane polymer yakaparadzirwa mu polycarbonate (PC). Iyi silicone-based additive inonyanya kushanda kune PC-inoenderana resin masisitimu. Inonatsiridza zvivakwa zvekugadzirisa uye pamusoro pemhando nekusimudzira kuyerera kweiyo resin, kufambisa kuzadza mold uye kuburitsa, kuderedza extruder torque, kudzikisa iyo coefficient yekupokana, uye kupa yepamusoro mar uye abrasion kuramba. Pamusoro pezvo, iyi siloxane-based masterbatch inoshanda senge anti-scratch additive, ichiita kuti ive mhinduro yakanakisa yekuwedzera kukwenya kuramba kwePC zvigadzirwa uye pakupedzisira kuvandudza kuita kwavo kwese uye kusimba.
2. UV-Inopora Yakaoma Coatings neNanotechnology
Nyorera epamberi siloxane-yakavakirwa kana hybrid organic-inorganic yakaoma machira (semuenzaniso, Momentive SilFORT AS4700 kana PPG's DuraShield). Aya mabhanhire anowana kuomarara kwepenzura kusvika ku7H-9H, achivandudza zvakanyanya kuramba.
Batanidza mabhanhire anorapika eUV ane nanoparticles (semuenzaniso, silica kana zirconia) kuti uwedzere kusimbaradzwa kweabrasion.
Benefit: Inopa chinodzivirira kubva kune zvikwambo, makemikari, uye UV kuparara, yakanakira optical uye mota application.
Kushandisa: Shandisa dip-coating, spray-coating, kana kuyerera-coating kune yunifomu ukobvu (5-10 µm).
3. Nanocomposite Reinforcement
Wedzera nanofillers se nanosilica, alumina, kana graphene oxide (0.5-2% nehuremu) kuPC matrix. Izvi zvinowedzera kuomarara kwepamusoro uye zvinonatsiridza kupfeka kusamira pasina kukanganisa zvakanyanya kujeka kana saizi yechikamu iri <40 nm.
Muenzaniso: Zvidzidzo zvinoratidza 1% nanosilica muPC inogona kuvandudza Taber abrasion kuramba ne20-30%.
Zano: Shandisa zvinopindirana (semuenzaniso, silane coupling agents) kuona kupararira kwakafanana uye kudzivirira kusangana.
4. PC Blends yeBalanced Performance
Blend PC nePMMA (10-20%) kuti uwedzere kuomarara kwepasi kana nePBT yekuvandudza kuomarara uye kupfeka kuramba. Izvi zvinosanganisa chiyero kukwenya kuramba nePC's inherent impact simba.
Muenzaniso: Musanganiswa wePC/PMMA ne15% PMMA unogona kuwedzera kuomarara kwepasi uchichengeta kujeka kwezvikumbiro zvekuratidzira.
Yambiro: gadzirisa musanganiswa ratios kuti udzivise kukanganisa PC kugadzikana kwekupisa kana kuoma.
5. Mamiriro Epamusoro eKushandura Kwepamusoro
Kurapa kwePlasma: Isa plasma-inonatsiridza kemikari vapor deposition (PECVD) kuisa matete, akaomarara machira sesilicon oxynitride (SiOxNy) paPC nzvimbo. Izvi zvinovandudza scratch resistance uye kupfeka zvinhu.
Laser Texturing: Gadzira diki- kana nano-chikero mameseji paPC pamusoro kuti uderedze nzvimbo yekubata uye kuparadzira zvikweshwa, uchivandudza aesthetic durability.
Benefits: Kunyora mameseji kunogona kuderedza kukwenya kunoonekwa kusvika ku40% mune yakakwirira-contact application.
6. Additive Combitions for Synergy
Sanganisa silicone additives nezvimwe zvinoshanda zvinowedzera sePTFE (polytetrafluoroethylene) micropowder (0.5-1%) ye synergistic mhedzisiro. PTFE inosimudzira lubricity, nepo silicone inovandudza kupfeka kuramba.
Muenzaniso: Musanganiswa we2% silicone masterbatch uye 0.5% PTFE unogona kuderedza mareti ekupfeka ne25% mukutsvedza maapplication.
7. Optimized Processing Conditions:
Shandisa high-shear musanganiswa kuparadzira zvakafanana zvinowedzera uye mafirita. Chengetedza tembiricha yePC yekugadzirisa (260-310 ° C) kudzivirira kudzikisira.
Shandisai nzira dzemajekiseni dzakakwenenzverwa (semuenzaniso, kuumba majekiseni ane mold dzakakwenenzverwa) kuderedza hurema hwepamusoro hunogona kutanga makwara.
Anneal yakaumbwa zvikamu pa 120-130 ° C kuti ibvise kushushikana kwemukati, kuvandudza kushanda kwenguva refu kwekupfeka.
Innovation Watch: Kuzviporesa uye DLC Coatings paKusimuka
Tekinoroji dziri kusimukira senge yekuzvipodza machira (yakavakirwa pa polyurethane kana siloxane chemistry) uye madhaimondi-senge kabhoni (DLC) machira anopa ramangwana-uchapupu mhinduro kune yekupedzisira-inogara, yakakwirira-inobata PC application. Ndichiri kudhura-kurambidza zvigadzirwa zvemusika-zhinji, matekinoroji aya anoratidza vimbiso mune zvemhando yepamusoro zvemagetsi, mota, uye aerospace.
Inokurudzirwa Nzira Yekunyatso Kuita muInjiniya Thermoplastics
Kune vagadziri vanotsvaga inoshanda, scalable mhinduro yekuvandudza PC kusimba kwepamusoro, isu tinokurudzira:
1)2% UHMW Silicone Yekuwedzera yemukati lubricity
2) Siloxane-based UV Coating + 1% Nano Silica yekuoma kwepamusoro
3) Micro-Texturing kuburikidza neLaser Molding kuvanza mavanga
Iyi nzira ine mativi matatu inoburitsa chiyero chemutengo-kushanda, kugadzirisa kuenderana, uye kuita, zvichiita kuti ive yakanaka kune zvigadzirwa zvakafumurwa kupfeka kwemazuva ese uye zvinoda kwenguva refu aesthetics.
