Apamwamba PTFE odana avale

Mwambo-m'zigawo za PTFE kuonjezera moyo utumiki wa zida ndondomeko (makamaka poyera TV abrasive) atatu - kanayi.

Amadziwika kuti malangizo waukulu dzimbiri makampani mankhwala ndi kuteteza zitsulo. Ngakhale kusintha apitirize khalidwe la mapulasitiki ndi nsanganizo, ambiri akubera lero zipangizo zamakono akadali anapanga zitsulo.

PTFE mankhwala ndi mkulu avale kukana. Monga momwe nkhaniyi bwino khalidwe mayunitsi, ndi kuwongolera zinthu makina monga kutsetsereka mayendedwe, liners ndi cuffs taona zikwi makasitomala "Eco-RTI-Ndagwira". Pakati pawo, choyamba mankhwala kapangidwe mabizinezi, zomwe, chifukwa cha khalidwe la PTFE akhoza kuchepetsa ndalama zokonzetsera za compressors, zipangizo makina ndi mitundu yonse ya mayunitsi kukhululukirana.

Pankhani kuuma mtima kwa mankhwala, izi PTFE polima kuposa ngakhale ntchito pamaso detonation kupopera pa ndodo pisitoni. Yachokera pa polymerization kupanga fluoroplastic tetrafluoroethylene amapereka imachita izo Brinell kuuma mpaka 40 MPa ndi zayamba ziro porosity. Chifukwa cha njira mankhwala, ndi osalimba chuma cha 2200 makilogalamu / cm3, amene, pansi ndi chindodo elekitironi maso kapangidwe ali pamwamba otukukira kunja. Izi pamwamba pang'ono anamaliza ndi wosiyana kwambiri ndi concave, ndi m'mbali mwa dongosolo, mmene zipangizo wosakhazikika kuvala.

Anadzazidwa PTFE ndi pakati pa ma polima ochepa amene angagwiritsidwe yopangidwa kuchokera ku miyambo ya mapampu ndi centrifugal. The ntchito yotsirizira poyerekeza ndi analogues ku zitsulo (ndi moyang'ana ❖ kuyanika amalimata) ndi kuthetseratu kusiyana zedi matenthedwe yowonjezera akalowa ndi zitsulo. Ogulitsa, redistributors ndi kusindikiza - valavu mkati - komanso kuteteza kugwiritsa ntchito mankhwala fluoropolymer.

Losindikizidwa seams, tepi Fum ndi vuto lililonse ntchito.

Chifukwa PTFE preforms chopangidwa Kakhungu, gaskets ndi O-mphete, amene ntchito si kwenikweni amafuna yokonza njira ndi mwadzidzidzi. Ogwira si kukwaniritsa mkulu Brinell kuuma mayunitsi 20-25 kuposa cha kuuma kwa zipangizo zina pa msika. Pamodzi ndi ziro madzi mayamwidwe PTFE ndodo kapena mbale mbali yofunika kwambiri mu kuchepetsa mphamvu abrading poyerekezera kauntala kusuntha pamalo.

Mosiyana, nsanganizo osiyanasiyana concave microstructure, mphete ndi bushings wa polytetrafluorethylene silidzaonongeka ndi spalling kuposa khola osachepera kukhululukirana. Komanso mphamvu ndiponso kudalirika kwa mfundo zina, mipata ndi fasteners kulowererana zitha kupereka tepi Fum analenga kuchokera ku PTFE chingwe chabwazi kuti anatsekera polumikizana ndi hayidiroliki. Komanso gulu Fum ugule amakonda kuteteza mabowo ogwiritsa ndi otsika nthunzi mayamwidwe ndi gasi.
