Plastic King-Polyetherketone PEEK

PEEK imapangidwa ndi kutulutsa kosalekeza: ndodo ya PEEK, mbale ya PEEK, chubu cha PEEK, filimu ya PEEK, pepala la PEEK, ulusi wa PEEK, kapilari ya PEEK; polyetheretherketone (PEEK) ndi filimu yowonjezera yokhala ndi kristalo kochepa, ndipo nthawi zambiri imafunika kuphatikizidwa ndi ulusi wa kaboni, ulusi wagalasi, ulusi wa melamine ndi zinthu zina kuti igwiritsidwe ntchito. Mafilimu a polyetheretherketone (PEEK) osakanikirana amatha kutambasulidwa ndikutenthedwa kuti awonjezere mphamvu ndi kukana kutentha. Filimu ya polyetheretherketone (PEEK) yotambasulidwa komanso yotenthedwa ili ndi malo osungunuka 80℃ kuposa filimu ya PET.

Ubwino ndi kuipa kwa PEEK

Ubwino wa PEEK

Kukana dzimbiri, kuletsa ukalamba; kukana kusungunuka; kutentha kwambiri, ma frequency ambiri komanso magwiridwe antchito amphamvu kwambiri; kulimba ndi kulimba; mikhalidwe yofunikira kukula kolondola; kukana ma radiation, kukana kuvala, mikhalidwe yokana dzimbiri; kukana hydrolysis, kutentha kwambiri ndi kuthamanga kwambiri kumatha kukhalabe ndi makhalidwe abwino kwambiri; kusintha chitsulo chopepuka ngati zigawo za ulusi wa kuwala; kukana kuvala bwino, mphamvu zamagetsi zoteteza kutentha; zigawo zofunikira mphamvu zambiri zamakanika; mpweya wochepa wa soya ndi mpweya woopsa

Zoyipa za PEEK

Kubaya, kupanga ndi #kutulutsa mbiri mikhalidwe ya ndondomekoyi ndi yovuta

Madera akuluakulu ogwiritsira ntchito a PEEK

PEEK imalimbana ndi hydrolysis ndipo ndi yosavuta kuikonza, ndi zina zotero, ndipo yakhala ikugwiritsidwa ntchito m'magawo a ndege, kupanga magalimoto, zamagetsi ndi zamagetsi, zamankhwala ndi kukonza chakudya; imagwiritsidwa ntchito kwambiri m'makina, petrochemical, mphamvu ya nyukiliya, zoyendera njanji ndi zina, monga ma compressor valve plates, mipando ya steam ball valve yokhala ndi mphamvu yothamanga kwambiri, ma bearing cages, ma gear a chemical pump, ma sliding bearing, seals, piston rings, sliding shoes ndi zina zamakina, khalidwe lopepuka la chinthu, nthawi yayitali yogwira ntchito, komanso kuchepetsa phokoso logwira ntchito la makina. Kuphatikiza apo, chifukwa PEEK ili ndi insulator yabwino yamagetsi, imatha kusungabe zinthu zabwino zotetezera magetsi pansi pa mikhalidwe yovuta yogwira ntchito monga kutentha kwambiri, voltage yambiri komanso chinyezi chambiri.

Zinthu za PEEK

Monga pulasitiki yopangidwa ndi theka-crystalline, PEEK siisungunuka m'zinthu zonse zosungunulira kupatula sulfuric acid yokhazikika, kotero imagwiritsidwa ntchito kwambiri popanga ma valve plates a compressor, mphete za piston, zosindikizira, ndi zida zosiyanasiyana zamapampu ndi zida za valve. Utomoni wa PEEK ukhozanso kutsekedwa kwa mphindi 3000 pa 134℃. Khalidweli limapangitsa kuti ikhale yoyenera kupanga zida zopangira opaleshoni ndi zamano zomwe zimafunikira kwambiri kuyeretsa komanso kugwiritsidwa ntchito mobwerezabwereza.

Kukonza kwa PEEK

● Ukadaulo wowonjezera kutentha ndi kuwongolera kutentha kwa uvuni:
 #Kutulutsa Ukadaulo wopangira zinthu umaphatikizapo kuphimba waya, mbiri ya chitoliro cha chitoliro, pepala la filimu ndi kupanga monofilament. Zotulutsa zonse zimakhala ndi screw extruder imodzi, koma zida zotsikira pansi monga mutu, die, setting, cooling, traction, stretching, calendering, ndi winding sizili zofanana.
Chotenthetsera chachitsulo kapena chadothi chomwe chili pa mbiya chiyenera kuphimba malo onse a mbiya yachitsulo ndipo chikhoza kutenthedwa kufika pa 400℃±2℃ kuti kutentha kugawikane mofanana.

● Kutentha kwa kuumba:
Kutentha kwa PEEK kuumba ndi madigiri 320 ~ madigiri 390, kutentha kwa kuphika ndi 160 ~ 1855H ~ 8H, kutentha kwa nkhungu ndi 140 ~ 180, kutentha kwa nkhungu ndi kwakukulu kwambiri, ndipo kuwonongeka kwa #extruder' Skurufu ndi yoopsa kwambiri. Mukakhazikitsa liwiro la skurufu, liwiro liyenera kukhala lachangu kwambiri, ndipo kuthamanga kwa jakisoni ndi 100~130MPa. Liwiro la jakisoni ndi 40~80.

● Malangizo a malamulo:
Pambuyo poti chitolirocho chatha, sikulu iyenera kutsukidwa mwachangu ndi sera wa PE pakapita nthawi, ndipo zinthu za PEEK siziyenera kuloledwa kukhala mu sikulu. Sikuluzo za mtundu wa PVC zomwe zimatulutsidwa ndi PEEK koma zimakanikizidwa mosalekeza sizikulimbikitsidwa, chifukwa sikuluzo ilibe malo odyetsera, zomwe zimapangitsa kuti pulasitiki ikanikize ikangolowa mu mbiya, zomwe zimapangitsa kuti screw torque ikhale yambiri. Kusefa kwa PEEK melt kumakhudza bwino kufanana kwa mawonekedwe enieni a extrusion; gwiritsani ntchito 20/60/250/60/ Chipangizo chophatikiza fyuluta chopangidwa ndi waya wosapanga dzimbiri wa chitsulo chosapanga dzimbiri wa 250 mesh chingapeze zotsatira zabwino zosefera continuous flow melt.
