Polyamide (PA66), inozivikanwawo seNylon 66 kana polyhexamethylene adipamide, ipurasitiki yeinjiniya ine mashandiro akanaka, akagadzirwa kuburikidza nepolycondensation yehexamethylenediamine uye adipic acid. Iine anotevera akakosha maitiro:

Kusimba Kwakakwirira uye Kusimba: PA66 ine yakakwira mechaniki simba, elastic modulus, uye kuomarara kana ichienzaniswa nePA6.

Yakasarudzika Wear Resistance: Seimwe yeakanakisa kupfeka-inodzivirira polyamides, PA66 inokunda mukushandisa senge mekiniki zvikamu, magiya, mabhengi, uye zvimwe zvinopfekwa zvinodzivirira.

Yakanakisa Heat Resistance: Nekunyunguduka kwe250-260 ° C, PA66 ine yakanyanya kupisa kupisa kana ichienzaniswa nePA6, ichiita kuti ive yakakodzera kune yakakwirira-tembiricha nharaunda.

Yakasimba Chemical Resistance: PA66 inopesana nekuora kubva kumafuta, acids, alkalis, uye akasiyana makemikari.

Yakanaka Kuzvinatsa Zvivakwa: Pamusoro pekupfeka kuramba, PA66 inoratidza yekuzvizora zvivakwa, yechipiri kuPOM (Polyoxymethylene).

Yakanaka Stress Cracking Resistance uye Impact Resistance: PA66 ine yakanakisa kuramba kushushikana kwekupwanya uye yakanaka kukanganisa simba.

Dimensional Kugadzikana: PA66 ine yakaderera mwando kunyura kana ichienzaniswa nePA6, kunyangwe hunyoro huchiri kukwanisa kukanganisa kugadzikana kwayo.

Wide Range Yekushandisa: PA66 inoshandiswa zvakanyanya mumichina zvikamu zvakatenderedza injini dzemotokari, zvemagetsi nemagetsi zvishandiso, magiya emaindasitiri, machira, nezvimwe.

Kunyangwe PA66 iine mabhenefiti akasiyana, kusamira kwayo kwekupfeka kunogona kuvandudzwa kuti ishandiswe munzvimbo dzinoda maindasitiri.

Ichi chinyorwa chinoongorora nzira dzakasimbiswa dzekugadzirisa PA66 uye chinosuma SILIKE LYSI-704, a.silicone-based lubricant processing additiveinopa kukwirira kupfeka kuramba, uye kusimba kana ichienzaniswa neyakajairwa PTFE mhinduro.

Chii Chakanyanya Kugadziridza Tekinoroji Inovandudza PA66's Wear Resistance Yekushandisa Maindasitiri?

Nzira dzechinyakare dzekuvandudza PA66 Wear Resistance yeKushandisa Maindasitiri:

1. Kuwedzera Kusimbisa Fibers

Girazi Fiber: Inowedzera kusimba kusimba, kuomarara, uye abrasion kuramba, zvichiita kuti PA66 ive yakasimba uye yakasimba. Kuwedzera kutenderedza 15% kusvika 50% girazi fiber inosimudzira zvakanyanya kupfeka kuramba uye kugadzikana.

Carbon Fiber: Inovandudza kukanganisa kuramba, kuoma, uye kuderedza uremu. Iyo inowedzerawo kupfeka kuramba uye simba remagetsi kune zvimiro uye zvepamusoro-kuita zvikamu.

2. Kushandisa Mineral Fillers

Mineral Fillers: Aya mafirita anoomesa iyo PA66 pamusoro, achidzikisa mareti ekupfeka munzvimbo dzinoshungurudza zvakanyanya. Ivo zvakare vanonatsiridza kugadzikana kwedimensional nekudzikisira kuwedzera kwemafuta uye kuwedzera kupisa kwekushisa kwekushisa, izvo zvinobatsira kuhupenyu hurefu hwesevhisi mumamiriro ekuda.

3. Kubatanidzwa kweSolid Lubricants uye Additives

Additives: Additives akadai PTFE, MoS₂, kanasilicone masterbatcheskuderedza kukweshera uye kupfeka pamusoro pePA66, zvichitungamira kukushanda kwakapfava uye nekuwedzera chikamu chehupenyu, kunyanya mukufambisa mekiniki zvikamu.

4. Kemikari Kugadziriswa (Copolymerization)

Kemikari Kugadziridzwa: Kuunza mitsva yezvimiro zvikamu kana copolymers kunoderedza kunyura kwemwando, kunowedzera kuoma, uye kunogona kuvandudza kuoma kwepasi, nekudaro kuwedzera kupfeka kuramba.

5. Impact Modifiers uye Compatibilizers

Impact Modifiers: Kuwedzera maitiro ekugadzirisa (semuenzaniso, EPDM-G-MAH, POE-G-MAH) inovandudza kuomarara uye kusimba pasi pekunetsekana kwemuchina, izvo zvisina kunanga zvinotsigira kusapfeka nekudzivirira kutsemuka.

6. Optimized Processing uye Drying Techniques

Kuomesa Kwakakodzera uye Kudzora Kugadziriswa: PA66 ndeye hygroscopic, saka kuomeswa kwakakodzera (pa80-100 ° C kwemaawa 2-4) kusati kwagadziriswa kunokosha kuti udzivise hurema hune hukama hunogona kukanganisa kusapfeka. Pamusoro pezvo, kuchengetedza tembiricha inodzorwa panguva yekugadziriswa (260-300 ° C) inoita kuti zvinhu zvirambe zvakasimba uye zvakagadzikana.

7. Surface Treatments

Pamusoro Coatings uye Mafuta ekuzora: Kuisa mafuta ekunze kana machira epamusoro, akadai seceramic kana simbi yekupotera, inogona kuderedza zvakanyanya kupokana nekupfeka. Izvi zvinonyanya kubatsira kune yakakwirira-kumhanya kana yakakwirira-mutoro maapplication apo kumwe kudzikiswa kwekukwesha kunodiwa kurebesa hupenyu hwesevhisi.

Innovative PTFE-Yemahara Solution ye Wear-Resistant Polyamide (PA66) Engineering Plastics: SILIKE LYSI-704

Kupfuura zvakajairwa nzira dzekugadzirisa,SILIKE LYSI-704-iyo silicone-based wear-resistant additive-inoratidza budiriro yakakosha mukuvandudza kusimba kwePA66 uye kuita.

Kugadziriswa Plastics Technology Overview

LYSI-704 ndeye silicone-yakavakirwa yekuwedzera iyo inosimudzira PA66 yekupfeka kuramba nekugadzira inopfuurira lubrication layer mukati mepolymer matrix. Kusiyana nemagariro echinyakare-anodzivirira mhinduro senge PTFE, LYSI-704 inoparadzira zvakafanana mukati menaironi pamwero wakaderera wekuwedzera.

LYSI-704 Makiyi mhinduro einjiniya Plastics:

Superior Wear Resistance: LYSI-704 inopa kupfeka kuramba kunofananidzwa nePTFE-yakavakirwa mhinduro asi nemutengo wakaderera kwezvakatipoteredza, sezvo isina fluorine, kugadzirisa kunetseka kuri kuwedzera pamusoro pePFAS (per- uye polyfluoroalkyl zvinhu).

Yakanatsiridzwa Impact Simba: Pamusoro pekusimudzira kupfeka kuramba, LYSI-704 inovandudzawo simba rekuita, iro raimbove rakaoma kuwana panguva imwe chete nekukwirira kupfeka kuramba.

Aesthetic Improvements: Kana yakasanganiswa muPA66 ine girazi fibers, LYSI-704 inogadzirisa nyaya yefiber inoyangarara, inonatsiridza hunhu hwepamusoro uye ichiita kuti ive yakanaka kune maapplication uko kutaridzika kwakakosha.

Sustainability: Iyi silicone-based tekinoroji inopa yakasarudzika imwe nzira kune PTFE, inoderedza kushandiswa kwezviwanikwa uye kabhoni tsoka uku uchiunza kushanda kwepamusoro.

Experimental Results

Mamiriro ekuyedzwa kwekupfeka bvunzo: kushandiswa kwehuremu hwegumi-kirogiramu, simba remakirogiramu makumi mana ekumanikidza pamuenzaniso, uye nguva yemaawa matatu.

Mune PA66 zvinhu, friction coefficient yemuenzaniso usina chinhu ndeye 0.143, uye kurasikirwa kukuru nekuda kwekupfeka kunosvika 1084mg. Kunyangwe iyo friction coefficient uye kuwanda kupfeka kwesample ine yakawedzera PTFE yaramba zvakanyanya, haikwanise kuenderana neLYSI - 704.

Kana 5% LYSI - 704 yawedzerwa, iyo friction coefficient ndeye 0.103 uye yakawanda inopfeka i93mg.

Nei silicone masterbatch LYSI-704 Pamusoro pePTFE?

• Kufananidzwa kana nani kupfeka kuramba

• Hapana PFAS zvinonetsa

• Chiyero chekuwedzera chepasi chinodiwa

• Yakawedzerwa mabhenefiti ekupedzisa kwepamusoro

Ideal Applications:

Anti-wear additive LYSI-704 inonyanya kubatsira mumaindasitiri anoda zvese zviri zviviri kuita kwepamusoro uye kusimba, senge mota, zvemagetsi, uye maindasitiri muchina. Yakanakira maapplication akaita semagiya, mabheri, uye mamekiniki zvinhu zvakafumurwa kupfeka kwakanyanya uye kushushikana.

Mhedziso: Simbisa Yako Nylon Zvikamu neSILIKE Wear-Resistant Agent LYSI-704

Kana iwe uchitsvaga mhinduro dzekusimudzira kusapfeka kwenylon yako 66 zvikamu kana mamwe mapurasitiki einjiniya.,SILIKE lubricant LYSI-704 inopa inodzika, inogoneka imwe nzira kune yechinyakare zvinowedzera sePTFE Lubricants uye Additives. Nekuvandudza kupfeka kuramba, kusimba kwesimba, uye mhando yepamusoro, iyi silicone-based additive ndiyo kiyi yekuvhura iyo yakazara mukana wePA66 mumaindasitiri maapplication.

Kuti uwane rumwe ruzivo nezve iyo silicone yekuwedzera LYSI-704 inogona kuvandudza yako PA66 zvikamu, bata SILIKE Technology nhasi. Isu tinopa zano remunhu, masampuli emahara, uye yakadzama tekinoroji rutsigiro kuti ikubatsire kuita yakanakisa gadziriso tekinoroji sarudzo dzezvido zvako.
