Igihe PTFE yubushyuhe bwo hejuru kunyerera .
Creep ni buhoro, ihindagurika ryibintu munsi yumutwaro uhoraho mugihe. Ku bushyuhe bwicyumba, kaseti ya PTFE irashobora gusa nkaho ihagaze. Ariko kuri 200 ° C cyangwa ndetse na 260 ° C - urwego rusanzwe rukora - urwego rufatika rushobora koroshya no gutemba, kandi substrate ya PTFE irashobora kunyura 'imbeho ikonje ' (kunyerera munsi yacyo).
Aokai PTFE yagerageje imyitwarire yikurikiranya mumasaha ibihumbi. Iyi ngingo isobanura uburyo ibizunguruka bisuzumwa, uburyo igipande gifatika hamwe na substrate buri wese atanga umusanzu, hamwe niyubaka kaseti irwanya kunyerera neza.
Niki Crip muri Tape ya PTFE - Ibipimo bibiri
Creep mubyukuri bivuga igisubizo cyibikoresho byibikoresho. Igikoresho gifatika hamwe na substrate imikorere ikoresheje uburyo butandukanye, nyamara byombi bigira ingaruka zikomeye kubirwanya muri rusange.

Ikibazo cyimiterere yakazi: Kaseti ya PTFE ikunze guhura nuburemere buri gihe kuri 200-260 ° C, kurenga imipaka yama mashanyarazi asanzwe. Ikizamini cyagutse cyo hejuru kirasabwa.
Ibikoresho bifata neza - Silicone PSA
Ibyuma bifata ibyuma byinshi bya PTFE bifata silicone ishingiye ku muvuduko ukabije w’umuvuduko ukabije w’ubushyuhe bwo hejuru, biterwa n’ibintu bikurikira:
Ikintu
Ingaruka kuri Kurwanya Kurwanya
Icyerekezo cyiza
Ubucucike
Urwego rwohejuru rwuzuzanya rwuzuye rwuzuye rwa elastike → hasi ihoraho
Ongera (ariko ntabwo ari hejuru kuburyo tack yambere yatakaye)
Uburemere bwa molekulari & imiterere
Uburemere buke bwa molekuline + vinyl / fenyl guhindura → imbaraga zifatika
Hejuru ya MW, fenyl silicone kubushyuhe bwinshi
Kuzuza ibyuzuzo (urugero, silika fumed)
Itezimbere cyane imbaraga zifatika, ituma kwisubiraho byoroshye (nka reberi) va gutembera neza (nka chewine)
Ongeraho 5-15% wuzuza uwuzuza
Ubunini bufatika
Igicucu cyinshi cyemerera kunyerera → kunyerera hejuru munsi yumutwaro umwe
Koresha igipande cyoroshye, kimwe cyo kurwanya anti-creep
Guhuza imiterere
Guhuza nabi bitera gukuramo ibishishwa biva muri substrate sl kunyerera hagati (ntabwo ari byinshi)
Koresha silicone primer, menya neza neza
Ibyingenzi byingenzi: Ifatanyirizo ya silicone yometseho ihura nubushyuhe bwihuse kubushyuhe bwo hejuru. Kaseti ya premium anti-creep ikoresha silicone-ihuza cyane-yuzuye-silicone hamwe niyuzuza ibyubaka kandi igenzurwa neza.
Aokai PTFE kaseti yubushyuhe bwo hejuru ikoresha silicone-ihuza cyane-silicone PSA hamwe na silika yongerewe imbaraga. Ikizamini cyigenga cyogupima kuri 260 ° C (1000g umutwaro, 12.5 × 25 mm hejuru) byerekana> amasaha 150 yo kunanirwa - bikwiranye no gusaba ubushyuhe bwo hejuru burigihe-imitwaro.
Substrate Ibiranga - PTFE Yashizwemo Fiberglass na Filime Yera ya PTFE
Inzira ebyiri nyamukuru zikoreshwa kuri kaseti ya PTFE, hamwe nibikorwa bitandukanye cyane:
Ubwoko bwa Substrate
Kurwanya Kurwanya
Urwego
Filime nziza ya PTFE
Abakene - bakunda gutemba bizwi cyane (imbeho ikonje). Ndetse no munsi yoroheje yoroheje iremereye munsi yo gushonga (327 ° C), ihinduka rinini ridasubirwaho ribaho kubera kunyerera kwa molekile.
Polimeri idashyizwemo imbaraga → iminyururu iranyerera hagati yumuntu uhangayitse
Imyenda ya fibre yatewe na PTFE (yiganje kuri kaseti yo hejuru)
Nibyiza - fibre yububiko bwa fibre yububiko bubuza neza ubukonje bwa PTFE
Imiterere igizwe: fibre yibirahure itwara umutwaro, PTFE itanga inkoni
Kuri fiberglass-yongerewe imbaraga substrate, kurwanya creep bigenwa na:
Ikintu
Ingaruka
Ububoshyi n'ubunini
Ubucucike bwinshi, imyenda iremereye → modulus ndende cyane → creep yo hasi
Byahinduwe byuzuye PTFE
Inyongeramusaruro (ifu ya fiberglass, grafite, fibre karubone) igabanya ingendo ya molekile ya PTFE → kongera imbaraga za substrate gukomera no guhangana n’ibikurura
Kuvura imyenda & impregnation yuzuye
Byuzuye neza PTFE ikubiyemo fibre yububiko bwa fiberglass yibumbiye hamwe kugirango wirinde kunyerera. Kwinjiza bidahagije → PTFE isigaye imbere yimyenda ya meshes iranyerera munsi yumutwaro
Substrate umubyimba & tekinike
Ibibyibushye, bisa neza substres → gukomera gukomeye → ndetse no gukwirakwiza imihangayiko → birinda kunyerera mugihe kitaragera.
Ibyingenzi byingenzi: Kubisanzwe-biremereye-ubushyuhe bwo hejuru, ntuzigere ukoresha kaseti ya PTEF yuzuye - izanyerera kuburyo budasubirwaho. Buri gihe hitamo fiberglass-ishimangirwa kaseti ya PTFE .

Icyifuzo gifatika: Kubisanzwe-biremereye-ubushyuhe bwo hejuru (urugero, gupfunyika imiyoboro ihindagurika munsi, gufata ibice kuri platine yashyutswe), saba amakuru yimyenda ihagaze kubushyuhe bwihariye nuburemere. Kugaragaza kaseti ya fiberglass ikomezwa na kaseti ya PTFE, ntabwo ari kaseti. Menya neza ko ibifatika ari byinshi-byambukiranya-silicone yuzuye.
Muncamake , kurwanya creep ya PTFE yubushyuhe bwo hejuru ya kaseti munsi yumutwaro muremure uhoraho biterwa nibice bibiri. Igice cya silicone PSA kigomba kuba gifite ubucucike buri hejuru, bwuzuza ibyuzuzo (silika fumed), hamwe nigitambaro cyoroshye kugirango kirwanya imitsi. Substrate igomba kuba fiberglass-yongerewe imbaraga PTFE - firime nziza ya PTFE izanyuramo ubukonje budasubirwaho mubushyuhe bwinshi. Fiberglass skeleton itwara umutwaro kandi igakomeza guhuza neza.
Mugihe uhitamo kaseti ya PTFE kugirango uhore-umutwaro wo hejuru-ubushyuhe bwo gusaba, ntuzigere utuza kaseti ya PTFE yuzuye. Buri gihe saba static shear data kubushyuhe bwawe bukora. Kandi wibuke: isano iri hagati yifatira hamwe na substrate ibintu nabyo - primer-ivura interineti irinda kunyerera.
Ukeneye kaseti irwanya PTFE kaseti kugirango ubushyuhe buringaniye burigihe? Aokai PTFE itanga kaseti ya fiberglass ikomezwa hamwe na silicone yo hejuru-ihuza-silicone ya PSA, yemejwe na 260 ° C yipimishije. Twandikire umutwaro wawe, ubushyuhe, nibisabwa igihe.
