Chitetezo Chosasunthika: Chifukwa Chake Besteflon, Wogulitsa Mapayipi Olimba a PTFE Osasinthasintha ku China, Amaika Patsogolo Mphamvu Yoyendetsa Mapaipi

Njira Yogwirira Ntchito Mosasinthasintha mu PTFE Systems

Chiwopsezo cha kutulutsa kwa electrostatic (ESD) pakusamutsa madzi chimachitika chifukwa cha kukangana pakati pa malo oyenda ndi payipi. PTFE mwachibadwa ndi insulator yayikulu. Pamene madzi osakhala a polar monga E85, methanol, kapena zosungunulira zosiyanasiyana zimayenda kudzera mu payipi pa liwiro lalikulu, ma elekitironi amachotsedwa pamwamba. Njirayi imapanga kusiyana komwe kungafikire ma volts zikwi zingapo. Popanda njira yoyendetsera magetsi, mphamvuyi imasonkhana mpaka itapeza malo ofooka kwambiri otulutsira madzi.

Kulephera kwakukulu pazochitika izi sikungokhala kung'anima kooneka. M'malo mwake, mphamvu yosonkhanitsidwa ingayambitse kuwonongeka kwa dielectric kwa zinthu za PTFE zokha. Izi nthawi zambiri zimapangitsa kuti "kutuluka kwa pinhole," komwe static arc imaboola m'liner kuti ifike ku chitsulo chosapanga dzimbiri chakunja. Kubowola kwa microscopic kumeneku kumawononga umphumphu wa msonkhano wonse, zomwe zimapangitsa kuti kutayike koopsa komwe kumakhala kovuta kuzindikira panthawi yowunikira nthawi zonse. Miyezo yamakampani monga SAE ndi ATEX tsopano imalola kuti mapayipi omwe amagwiritsidwa ntchito poyendetsa ndege, usilikali, ndi mafuta a ethanol azitha kutayidwa.

Uinjiniya Wazinthu: Yankho la Black Core

Kuyenda bwino kwa ma PTFE pa mapayipi kumafuna kusintha kwa zinthu moyenera panthawi yopanga.Besteflonimagwiritsa ntchito njira yapadera yotulutsira mpweya yomwe imasakaniza 100% virgin PTFE ndi carbon black yoyera kwambiri. Izi zimapanga cholumikizira chamkati chokhazikika, chomwe nthawi zambiri chimatchedwa "black core." Mosiyana ndi zokutira pamwamba zomwe zimatha kutha kapena kuipitsa madzi, netiweki yolumikizidwa iyi ya tinthu ta carbon imatsimikizira kugwira ntchito kwamagetsi kosalekeza nthawi yonse ya payipi.

Cholumikizira chowongolera chimagwira ntchito popanga njira yopitilira yamagetsi, zomwe zimathandiza kuti ma static charge ayende bwino kupita ku zitsulo zomangira zitsulo. Pamene payipi yolumikizirana bwino ndi 304 kapena 316L yoluka chitsulo chosapanga dzimbiri, mphamvuyo imasamukira ku malo oyambira makina kapena galimoto. Kuti zigwirizane ndi kayendedwe ka kayendedwe ka madzi kosiyanasiyana, monga kulowetsa mafuta kapena kubwezeretsa nthunzi, njira zoyendetsera magetsizi zimapezeka m'mabowo osalala komanso ozungulira.

Njira Zosankhira Zanzeru za Mapayipi Otsutsana ndi Kusinthasintha

Mainjiniya ayenera kudziwa nthawi yoyenera kugwiritsa ntchito ma anti-static pa ma PTFE hopes potengera zinthu zinazake. Mtundu wa media ndiye muyezo woyamba. Madzi osakhala a polar okhala ndi magetsi ochepa, monga ma hydrocarbon ndi ma dry solvents, ndi omwe amapezeka kwambiri popanga ma static. Kuphatikiza apo, machitidwe omwe amagwiritsa ntchito ma flow a magawo awiri, monga mpweya wonyamula ufa wabwino kapena madontho, amawonjezera kwambiri kuchuluka kwa ma charge.

Mikhalidwe yogwirira ntchito imalimbikitsanso kufunikira kwa conductivity. Kuthamanga kwa kayendedwe ka madzi kopitirira mita imodzi pa sekondi imodzi kapena machitidwe omwe amadziwika ndi ma pulses oyambira nthawi zambiri amapanga milingo yayikulu ya kukangana. Malo okhala ndi chinyezi chochepa amawonjezeranso zoopsa zosasunthika chifukwa chinyezi mumlengalenga sichingathandize kuchotsa mphamvu pamwamba. Ngakhale malamulo am'deralo sakulamula mwamphamvu, opanga zida zoyambirira ambiri (OEMs) amagwiritsa ntchito ma conductive hoses ngati njira "yotetezeka". Kuchulukaku kumatsimikizira kuti makinawa amakhalabe otetezedwa ndi zinthu zosayembekezereka zachilengedwe kapena zogwirira ntchito.

Kutsimikizika ndi Kukhazikika kwa Kukhazikitsa

Kusintha kuchoka pa magawo aukadaulo kupita ku chitetezo chenicheni cha malo kumafuna njira yotsimikizira yotsekedwa. Mapayipi oyendetsera mpweya abwino kwambiri amayesedwa mwamphamvu kuyambira kumapeto mpaka kumapeto kuti atsimikizire kuti kukana kwamagetsi kumakhalabe mkati mwa malire otetezeka, nthawi zambiri pansi pa 10^6 ohms. Mayesowa amatsimikizira kuti payipi imagwira ntchito yake yotulutsa mpweya kuchokera ku imodzi kupita ku ina popanda kusokoneza.

Komabe, payipi yokha ndi gawo limodzi lokha la dongosolo lotetezeka. Kugwira ntchito bwino kwa cholumikizira choyendetsera mpweya kumadalira kwathunthu kulimba kwa nthaka. Cholumikiziracho chiyenera kugwiritsa ntchito zida zogwirizana ndi zitsulo zomwe zimasunga kulumikizana kotetezeka ndi gawo lamkati lokhala ndi mpweya wochuluka wa kaboni. Ngati njira yolumikizira nthaka yasweka pamalo oyikapo, mphamvu yosasunthika idzakhalabe yotsekedwa ngakhale kuti cholumikiziracho chili ndi mphamvu yoyendetsera mpweya. Kukhazikitsa kwaukadaulo kuyenera nthawi zonse kutsimikizira kuti dera lonse lamadzimadzi limalumikizidwa pamalo amodzi kuti kupewe kusiyana komwe kungachitike.
