Ruzivo rweindasitiri pakuvandudza mashandiro eNylon muzvishandiso zvekupfeka zvakanyanya

Munzvimbo iri kuramba ichichinja-chinja yemapurasitiki einjiniya, zvinhu zvenaironi zvisingaparare zvinoramba zvichitamba basa rakakosha mumaindasitiri akasiyana-siyana. Kubva kuzvinhu zvemotokari kusvika kumichina yeindasitiri, kudiwa kwemhinduro dzenaironi dzinogara kwenguva refu uye dzisinganyanyi kukweshana kwakakurudzira hunyanzvi hukuru musainzi yezvinhu.

ChinyakareMhinduroKudzivirira Kupfeka kweNylon

Vemainjiniya vakagadzira nzira dzakasiyana-siyana dzekuwedzera kusakara kwePA6 nePA66, mhando dzenylon dzinonyanya kushandiswa mumaindasitiri.

1. Kusimbiswa kweGirazi neFiber:Nyoni yakasimbiswa nefaibha yegirazi (GF/PA6, GF/PA66) inoumbwa nekusanganisa magirazi kuita nylon matrix, zvichigadzira composite inoshanda zvakanyanya inovandudza hunhu hwemakanika. Mafiber aya anoumba network inosimbisa ye3D, ichivandudza simba rekudhonza (kusvika 4×), kuomarara (3–5× higher flexural modulus), uye kuramba kupisa (50–100°C higher HDT) kuburikidza nekufambiswa kwemutoro zvinobudirira. Zvichibva pahuwandu hwefaibha, macomposites aya anotangira pafaibha shoma (10%-20%), faibha yepakati (25%-35%), faibha yepamusoro (40%-50%), uye faibha yepamusoro (>50%). Hunhu hwefaibha hunopfuura 30% hunonyanya kuvandudza kuramba kupfeka. Musanganiswa uyu unoita kuti ive sarudzo yepamusoro yekushandiswa kwemaindasitiri kwakaoma.

2. Kusimbisa Kabhoni Fiber:Kuwedzera firita dzekabhoni kuPA6/PA66 kunovandudza zvakanyanya simba remuchina uye kuramba kupfeka. Kusiyana nezvimwe zvinhu zvinosimbisa, firita yekabhoni yakapfava uye haina kusimba zvakanyanya, ichidzivirira kukuvara kwesimbi panguva yekukweshana. Mwero wekuwedzera wakajairika unotangira pa5% kusvika 20%, uye mashandisirwo epamusoro anoshandisa kusvika 30%.

3. PTFE/PA6 Alloys:Nekukweshana kwakaderera zvakanyanya, PTFE inogadzira mafirimu ekuzora panguva yekukweshana, zvichiita kuti ive yakakodzera kushandiswa kwemutoro wakawanda. Mwero wekuwedzera wakajairika muPA6 unotangira pa15% kusvika 20%.

4. Molybdenum Disulfide(MoS2)/PA66 Alloys: Ichishanda senzira yekusimudzira kristalo, molybdenum disulfide inowedzera kristalo yenylon, zvichiita kuti nzvimbo dzakaoma uye dzisaparare. Kubatana kwayo nesimbi kunoita kuti izadze maburi madiki pasimbi, zvichiita kuti nzvimbo dzacho dzive dzakatsetseka. Izvi zvinoita kuti ive yakanaka kune nylon-metal friction applications, ine mwero wekuwedzera we3% kusvika 15%.

5. Graphite-Yakagadziriswa PA66:Zvinowedzerwa zvegrafiti zvinobudirira zvinoderedza ma "friction coefficients" ukuwo zvichiwedzera hunhu hwekuzvizora. Maumbirwo egrafiti ane zvidimbu zvinobvumira kutsvedza nyore nyore panguva yekukweshana, zvichideredza kupera. Kugadziriswa uku kunoshanda zvakanyanya munzvimbo dzemvura, nekuwedzera kwakajairika pakati pe3% ne15%.

Matambudziko Ari Kumuka Mukusapfeka Nylon: Kuenzanisa Mashandiro, Mutengo, uye Kugara Kwakagadzikana

Pasinei nemhinduro idzi dzakagara dziripo, vagadziri vanga vachinetseka kwenguva yakareba nekuenzanisa zvinodiwa pakushanda nemitengo uye kuwedzera kwezvinodiwa zvekuchengetedza. Zvimwe zvinowedzerwa zvechinyakare zvinowanzoda mazinga akakwira ekutakura, izvo zvinogona kukanganisa maitiro ekugadzirisa uye kuwedzera mitengo yezvinhu.

"Indasitiri iyi yanga ichitsvaga mhinduro dzinogona kudzivirira kupfekwa zvakanyanya pasina matambudziko anokonzerwa nezvinowedzerwa zvechinyakare," vanodaro vamwe nyanzvi dzeinjiniya yepolymer. "Mhinduro yakanaka inoda mwero mudiki wekuwedzera uku ichichengetedza kana kutovandudza hunhu hwemidziyo yepakutanga."

ZvitsvaMhinduro dzemapurasitiki ekugadzira eNylon asingapindike

Chengdu Silike Technology Co., Ltd. yave iri kambani inotungamira mukugadzira zvinhu zvitsva uye kugadzira zvinhu zvinowedzerwa zvesilicone polymer zvinoshanda zvakanyanya kubvira muna 2004. Tiine hunyanzvi mukugadzira tekinoroji yesilicone yeindasitiri yerabha nepurasitiki, tinopa zvinhu zvekugadzirisa zvemazuva ano zvinogadzirisa matambudziko akaomarara ekugadzira uye zvinovandudza hunhu hwezvinhu zvinoshandiswa mumaindasitiri epasi rose. Mukupindura matambudziko aya, takagadzira kambaniLYSI-704, chinowedzera kushanda zvakanaka chakavakirwa pasilicone, chisingapfeki,yakagadzirirwa kugadzirisa nayiloni uku ichitsigira kugadzirwa kwakasimba.

Sei SILIKE Isingapfeki LYSI-704 Ichichinja Mashandiro eNylon? Chii Chinoita Kuti LYSI-704 Isiyane?

Chinowedzerwa chitsva cheLYSI-704 chinodzivirira kupfekwa, chakavakirwa pamagadzirirwo epolysiloxane akagadzirwa zvakanaka, kusiyana nezvinowedzera zvechinyakare zvisingapfeki, LYSI-704 inoita kupararira kwakafanana mukati me matrices enylon nekuwedzera kwakaderera zvinoshamisa. Izvi zvinogadzira lubrication layer inogara iripo iyo inoderedza zvakanyanya friction coefficients uku ichichengetedza hunhu hwemaginicha hwechinhu chepasi.

"Chinoita kuti tekinoroji iyi ive inoshamisa zvikuru inyaya yekuti inoshanda zvakasiyana-siyana," inotsanangura kudaro nyanzvi yekutsvagisa nekugadzira kubva kuSILIKE iyo inotarisa pakushandiswa kwesilicone mupurasitiki dzeinjiniya. "Kana yakabatanidzwa muPA6+glass fiber systems kuburikidza ne melt compounding, LYSI-704 haingogumiri pakuramba kupfeka zvakanaka sezvinoita mhinduro dzePTFE asiwo inovandudza simba rekusimba - musanganiswa waimbofungidzirwa kuti haugoneki.

Zvichida zvakanyanya kune vagadziri vane hanya nekunaka, chinowedzera chepurasitiki /Modifier LYSI-704 chinogadzirisawo dambudziko rekufamba-famba kwefiber iro rave richitambudza nylon dzakasimbiswa negirazi, zvichivhura mikana mitsva yekushandisa uko kunaka kwepamusoro kwakakosha.

Uyezve, sezvo nyaya dzekuchengetedza zvakatipoteredza dzichiri kuramba dzichichinja sarudzo dzekusarudza zvinhu, LYSI-704 silicone-based chemistry inopa imwe nzira isina fluorine pane zvekuwedzera zvePTFE zvechinyakare, zvichienderana nezvirongwa zvepasi rose zvekuderedza kushandiswa kwemakemikari ane fluorine. Kugona kwetekinoroji iyi kupa mashandiro akanaka pamutengo wakaderera wekuwedzera zvinorevawo kuderedza kushandiswa kwezviwanikwa uye zvingangoderedza mafambiro ecarbon mukugadzirwa kwese.

Kune vagadziri vemapurasitiki einjiniya vari kutsvaga mikana yekukwikwidzana kuburikidza nekuvandudza zvinhu, matekinoroji aya ekuvandudza abrasion akavakirwa pasilicone anopa mikana inokwezva mumusika uri kuramba uchinetsa, ukuwo uchivhura mikana mitsva yekugadzira mashandisirwo.
Wagadzirira here kuvandudza zvikamu zvako zvenaironi netekinoroji itsva inodzivirira kupfekwa?

Kana uri kutsvagamhinduro dzinoshanda dzekuvandudza kuramba kusakara kwenaironi yakoZvikamu zvitsva, hunyanzvi hwakaita seSILIKE LYSI-704 hunodzivirira kupfekwa, zviratidzo zvitsva zvezvinhu zvakagadzirwa, uye ndiyo nzira yawagara wakamirira. Inopa mukana wekugara kwenguva refuimwe nzira yekuwedzera PTFE yechinyakareTaura nesu nhasi kuti muzive kuti chinhu ichi chitsva chinogadzirisa zvinhu chinogona sei kushandura mapurasitiki enyu ekugadzira zvinhu uku muchienderana nezvinangwa zvenyu zvekuchengetedza zvinhu.
