Polyamide (PA66), yomwe imadziwikanso kuti Nylon 66 kapena polyhexamethylene adipamide, ndi pulasitiki yopangidwa mwaukadaulo yokhala ndi magwiridwe antchito abwino kwambiri, yopangidwa kudzera mu polycondensation ya hexamethylenediamine ndi adipic acid. Ili ndi makhalidwe ofunikira awa:

Mphamvu Yaikulu ndi Kulimba: PA66 ili ndi mphamvu yapamwamba kwambiri ya makina, modulus yotanuka, komanso kulimba poyerekeza ndi PA6.

Kukana Kwabwino Kwambiri Kuvala: Monga imodzi mwa ma polyamides abwino kwambiri osatha kutha, PA66 imagwira ntchito bwino kwambiri monga zida zamakaniko, magiya, mabearing, ndi zida zina zosatha kutha.

Kukana Kutentha Kwambiri: Ndi kutentha kwa 250-260°C, PA66 imakhala ndi kutentha kwabwino kwambiri poyerekeza ndi PA6, zomwe zimapangitsa kuti ikhale yoyenera malo otentha kwambiri.

Kukana Mankhwala Kwambiri: PA66 imalimbana ndi dzimbiri lochokera ku mafuta, ma acid, ma alkali, ndi mankhwala osiyanasiyana.

Makhalidwe Abwino Odzipaka Mafuta: Kuwonjezera pa kusagwiritsidwa ntchito mopitirira muyeso, PA66 imadzipaka mafuta okha, yachiwiri kuposa POM (Polyoxymethylene).

Kukana Kupsinjika ndi Kukana Kukhudzidwa: PA66 ili ndi kukana bwino kupsinjika ndi kukana mphamvu.

Kukhazikika kwa Miyeso: PA66 ili ndi chinyezi chochepa poyerekeza ndi PA6, ngakhale chinyezi chingakhudzebe kukhazikika kwake kwa miyeso.

Mitundu Yosiyanasiyana ya Ntchito: PA66 imagwiritsidwa ntchito kwambiri m'zigawo zamakanika kuzungulira mainjini a magalimoto, zida zamagetsi ndi zamagetsi, zida zamafakitale, nsalu, ndi zina zambiri.

Ngakhale PA66 ili ndi ubwino wosiyanasiyana, kukana kwake kutopa kumatha kukonzedwanso kuti igwiritsidwe ntchito m'malo ovuta kwambiri m'mafakitale.

Nkhaniyi ikufotokoza njira zodziwika bwino zosinthira PA66 ndipo ikuwonetsa SILIKE LYSI-704, yomwe ndichowonjezera chopangira mafuta chochokera ku siliconeimapereka kukana kwapamwamba kwambiri kwa kuvala, komanso kukhazikika poyerekeza ndi njira zachikhalidwe za PTFE.

Ndi Ukadaulo Wotani Wosintha Umene Umapangitsa Kuti PA66 Isamavale Bwino Pogwiritsa Ntchito Mafakitale?

Njira Zachikhalidwe Zowongolera Kukana Kuvala kwa PA66 Pogwiritsa Ntchito M'mafakitale:

1. Kuwonjezera Ulusi Wolimbitsa

Ulusi wa Galasi: Umawonjezera mphamvu yokoka, kuuma, komanso kukana kukwawa, zomwe zimapangitsa PA66 kukhala yolimba komanso yolimba. Kuwonjezera ulusi wagalasi pafupifupi 15% mpaka 50% kumawonjezera kwambiri kukana kukalamba komanso kukhazikika.

Ulusi wa Carbon: Umathandiza kukana kugwedezeka, kuuma, komanso kuchepetsa kulemera. Umathandizanso kukana kukalamba komanso mphamvu ya makina pazida zomangira komanso zogwira ntchito bwino.

2. Kugwiritsa Ntchito Zodzaza Mineral

Zodzaza Mineral: Zodzaza izi zimalimbitsa pamwamba pa PA66, zimachepetsa kuwonongeka m'malo ovuta kwambiri. Zimathandizanso kukhazikika kwa mawonekedwe mwa kuchepetsa kukula kwa kutentha ndikuwonjezera kutentha komwe kumalepheretsa kutentha, zomwe zimapangitsa kuti ntchito ikhale yayitali m'malo ovuta.

3. Kuphatikizidwa kwa Mafuta Olimba ndi Zowonjezera

Zowonjezera: Zowonjezera monga PTFE, MoS₂, kapenama masterbatches a silikoniKuchepetsa kukangana ndi kuwonongeka kwa pamwamba pa PA66, zomwe zimapangitsa kuti ntchito ikhale yosalala komanso kuti nthawi yayitali ikhale yogwira ntchito, makamaka m'zigawo zoyenda.

4. Kusintha kwa Mankhwala (Copolymerization)

Kusintha kwa Mankhwala: Kuyika mayunitsi atsopano kapena ma copolymers kumachepetsa kuyamwa kwa chinyezi, kumawonjezera kulimba, ndipo kumatha kusintha kuuma kwa pamwamba, motero kumawonjezera kukana kutopa.

5. Zosintha ndi Zogwirizana ndi Impact

Zosintha Mphamvu: Kuwonjezera zosintha mphamvu (monga EPDM-G-MAH, POE-G-MAH) kumathandizira kulimba ndi kulimba pamene makina akukakamiza, zomwe zimathandiza mwanjira ina kukana kuwonongeka mwa kupewa kupangika kwa ming'alu.

6. Njira Zabwino Zokonzera ndi Kuumitsa

Kuumitsa Bwino ndi Kukonza Moyenera: PA66 ndi yosalala, kotero kuumitsa bwino (pa 80–100°C kwa maola 2-4) musanagwiritse ntchito ndikofunikira kwambiri kuti mupewe zolakwika zokhudzana ndi chinyezi zomwe zingakhudze kukana kuwonongeka. Kuphatikiza apo, kusunga kutentha kolamulidwa panthawi yokonza (260–300°C) kumaonetsetsa kuti zinthuzo zikhale zolimba komanso zokhazikika.

7. Mankhwala Okhudza Malo Ozungulira

Zopaka Pamwamba ndi Mafuta Opaka: Kupaka mafuta opaka pamwamba kapena zopaka pamwamba, monga zopaka za ceramic kapena zitsulo, kungachepetse kwambiri kukangana ndi kuwonongeka. Izi ndizothandiza makamaka pakugwiritsa ntchito mwachangu kwambiri kapena katundu wambiri komwe kuchepetsa kukangana ndikofunikira kuti nthawi yayitali ya ntchito ya chinthucho ipitirire.

Njira Yatsopano Yopanda PTFE Yopangira Mapulasitiki Osavala a Polyamide (PA66): SILIKE LYSI-704

Kupitilira njira zachikhalidwe zosinthira,SILIKE LYSI-704—chowonjezera cholimba chomwe chili ndi silicone—ndi chizindikiro cha kupita patsogolo kwakukulu pakukweza kulimba ndi magwiridwe antchito a PA66.

Chidule cha Ukadaulo wa Mapulasitiki Osinthidwa

LYSI-704 ndi chowonjezera chopangidwa ndi silicone chomwe chimawonjezera kukana kwa PA66 mwa kupanga mafuta okhazikika mkati mwa matrix a polymer. Mosiyana ndi njira zachikhalidwe zosatha kutha monga PTFE, LYSI-704 imafalikira mofanana mu nayiloni yonse pamlingo wotsika kwambiri wowonjezera.

Mayankho Ofunika a LYSI-704 a Uinjiniya wa Pulasitiki:

Kukana Kwabwino Kwambiri Kuvala: LYSI-704 imapereka kukana kofanana ndi njira zogwiritsira ntchito PTFE koma pamtengo wotsika kwambiri, chifukwa ilibe fluorine, zomwe zikukhudza nkhawa yomwe ikukulirakulira ya PFAS (zinthu za per- ndi polyfluoroalkyl).

Mphamvu Yowonjezera Mphamvu: Kuwonjezera pa kulimbitsa kukana kuvala, LYSI-704 imalimbitsanso mphamvu yolimbana ndi kuvala, zomwe kale zinali zovuta kuzikwaniritsa nthawi imodzi ndi kukana kuvala kwambiri.

Kukonza Zokongola: Ikaphatikizidwa mu PA66 ndi ulusi wagalasi, LYSI-704 imathetsa vuto la ulusi woyandama, kukonza mawonekedwe a pamwamba ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pomwe mawonekedwe ake ndi ofunikira.

Kukhazikika: Ukadaulo wopangidwa ndi silicone uwu umapereka njira ina yokhazikika m'malo mwa PTFE, kuchepetsa kugwiritsa ntchito zinthu ndi mpweya woipa komanso kupereka magwiridwe antchito apamwamba.

Zotsatira Zoyesera

Zofunikira pa mayeso oletsa kutopa: kugwiritsa ntchito kulemera kwa makilogalamu 10, kugwiritsa ntchito mphamvu ya makilogalamu 40 pa chitsanzo, ndi nthawi ya maola atatu.

Mu zinthu za PA66, chiŵerengero cha kukangana kwa chitsanzo chopanda kanthu ndi 0.143, ndipo kutayika kwa unyinji chifukwa cha kung'ambika kumafika pa 1084mg. Ngakhale kuti chiŵerengero cha kukangana ndi kung'ambika kwa chitsanzocho ndi PTFE yowonjezeredwa kwatsika kwambiri, sizingafanane ndi LYSI – 704.

Pamene 5% LYSI – 704 yawonjezeredwa, coefficient ya friction ndi 0.103 ndipo kulemera kwake ndi 93mg.

Chifukwa chiyani silicone masterbatch LYSI-704 imagwiritsa ntchito PTFE?

• Kukana kofanana kapena koyenera kuvala

• Palibe nkhawa za PFAS

• Kufunika kowonjezera pang'ono

• Ubwino wowonjezera pa kumalizitsa pamwamba

Mapulogalamu Abwino Kwambiri:

Chowonjezera choletsa kuvala LYSI-704 chimagwira ntchito bwino kwambiri m'mafakitale omwe amafuna magwiridwe antchito apamwamba komanso okhazikika, monga magalimoto, zamagetsi, ndi makina amafakitale. Ndi chabwino kwambiri pakugwiritsa ntchito monga magiya, mabearing, ndi zida zamakanika zomwe zimawonongeka kwambiri komanso zimapanikizika.

Pomaliza: Sinthani Zida Zanu za Nayiloni ndi SILIKE Wear-Resistant Agent LYSI-704

Ngati mukufuna njira zothetsera mavuto okhudzana ndi kuwonongeka kwa zida zanu za nayiloni 66 kapena mapulasitiki ena aukadaulo.,Mafuta a SILIKE LYSI-704 amapereka njira ina yatsopano komanso yokhazikika m'malo mwa zowonjezera zachikhalidwe monga PTFE Lubricants ndi Additives. Mwa kukonza kukana kutopa, mphamvu ya kugunda, komanso mtundu wa pamwamba, chowonjezera ichi chopangidwa ndi silicone ndiye chinsinsi chotsegulira mphamvu zonse za PA66 m'mafakitale.

Kuti mudziwe zambiri za momwe silicone additive LYSI-704 ingasinthire zinthu zanu za PA66, funsani SILIKE Technology lero. Timapereka upangiri wokhudza inu nokha, zitsanzo zaulere, ndi chithandizo chaukadaulo chozama kuti chikuthandizeni kupanga zisankho zabwino kwambiri pazinthu zaukadaulo zomwe zikugwirizana ndi zosowa zanu.
