Hi byihi vuyelo bya vulawuri bya web tension hi nkarhi wa endlelo ro peta ra Teflon high-temperature tape eka ku flatness ka PTFE substrate xikan’we naku fana ka adhesive coating?

I. Vuyelo eka ku Flatness ka PTFE Substrate

1. Ku Olovisa ka Tipulasitiki na Vuyelo bya 'Necking'

PTFE material yina modulus yale hansi ya elastic. Loko tension yi tlula mpimo wa yona wa elastic, ku olovisiwa ka plastiki loku nga hundzukiki ka humelela, leswi endlaka leswaku ku va na longitudinal elongation na transverse narrowing. Endzhaku kaloko tension yi humesiwile, substrate ayi koti ku tlhelela eka xivumbeko xa yona xosungula, leswi endlaka leswaku yiva na slackness, longitudinal wrinkles, xikan’we naku tiya lokunga ringaniki. Eka swiyimo swo tika, swivumbeko swa transverse wavy swinga vumbiwa.

2. Ku hlengeletiwa ka Creep (Cold Flow) Hi ku famba ka nkarhi

PTFE yi hundza eka ku khuluka ka pulasitiki hi ku nonoka ehansi ka ntshikelelo lowu nga heriki. Hi nkarhi wa maendlelo yo peta, substrate ya olova loko yi hisiwa endzeni ka oven yo omisa, naswona creep ya tiya. Ku leha loku kunga ringaniki kuva 'frozen' endzhaku ka ku kufumela, leswi endlaka leswaku kuva na kunga ringani ka le henhla kumbe ku leha ka swirhendzevutani, leswinga herisiwiki hi maendlelo lawa ya landzelaka.

3. Ku nonoka ka Transverse loku nga ringaniki

Ku nga fambelani kahle ka ti guide rollers kumbe ku kongomisiwa ka matlhelo loku nga kongomangiki swi nga vanga ku hambana ka tension exikarhi ka matlhelo na le xikarhi, leswi yisaka eka 'curled edges,' central blistering, kumbe single-side warping. Ku cinca cinca ka tension ya nkarhi na nkarhi swinga tlhela swi humesa ku cincana ka transverse 'tight-loose marks' eka vuandlalo bya substrate, leswinga kavanyeta hiku kongoma ku flatness.

II. Vuyelo eka ku fana ka ku peta ka Leyara yo namarhela

1. Ku Cinca-cinca ka Ntshikelelo Swi Cinca Xivandla xa Coating

Eka knife-over-roll coating, tension yi boha hiku kongoma mpimo wa ku khumbana exikarhi ka substrate na doctor blade. Loko tension yi tlakuka hi xitshuketa, substrate yi tshikileriwa swinene, leswi hungutaka ntiko wa coating; loko tension yihunguteka, substrate ya olova, leswi engetelaka ntiko wa coating. Ku cinca cinca koloko ku endla ku hambana ka nkarhi na nkarhi eka ku enta ka leyara yo namarhela ku ya hi tlhelo ra webu, leswi tiviwaka tanihi 'crosswise streaks' kumbe 'zebra marks.'

2. Ku ololoka ka substrate swi khumba ku hangalaka ka adhesive

Ku nonoka ngopfu swi olovisa filimi ya PTFE naswona swi humesa ti micro-wrinkles, leti endzhaku ti tekeleriwaka hi adhesive coating eka vuandlalo bya substrate lebyi nga ringaniki. Endzhaku kaloko tension yi humesiwile naswona film yi hungutekile endzhaku, adhesive layer yingava na ti micro-cracks hikokwalaho ka ntshikelelo lowunga ringaniki. Eka ti substrates ta lapi ra fiberglass, ku tsana ngopfu swi kurisa ti yarn interstices, leswi endlaka leswaku ku nghena ngopfu hi namarhela, ku nga khomiwi ka le henhla loku nga enelangiki, na vuandlalo byo peta lebyi nga riki na xivumbeko.

3. Vuyelo lebyi Hlanganisiweke Hi Nkarhi Wa Ku Hisisa Ni Ku Omisa

PTFE yina coefficient yale henhla ya thermal expansion. Endzeni ka oven yo omisa, loko ti multi-zone tension settings tinga fambelani, substrate leyi olovisiweke hi kuhisa yi endla secondary stretching, yi soholota wet adhesive layer xikan’we na yona, leswi endlaka leswaku kuva na coating yo olova naswona yinga ringani endzhaku ko omisiwa. Ku tsana lokunga fanelangiki eka ndzhawu yo kufumela swinga tlhela swivanga swirhumbana swa shrinkage eka semi-dry adhesive layer.

III. Maendlelo ya Nkoka ya Vulawuri

1. Swiyenge swo Pfuxeta na ku Pfuxeta

Kufanele ku cheriwa tension yale hansi swinene naswona yinga tshamisekangiki, ntsena leswi ringaneleke ku sivela substrate kuva yi rhurhumela, leswi pfumelelaka ku nghena eka ndzhawu ya coating eka xiyimo xa ntumbuluko naswona yi papalata ku ololoka ka ha ri emahlweni.

2. Swiyenge swo Omisa na ku Pfuxeta

Ku lulamisiwa kahle loku kongomeke hiku tirhisa ti floating rollers swifanele kutirhisiwa kuva swi tlherisela hiku gingiriteka ku andzisiwa ka mahiselo naku hunguteka ka substrate, naswona tension yale henhla eka tindzhawu ta mahiselo yale henhla yifanele ku papalatiwa swinene.

3. Xiyenge xa ​​ku tlherisela endzhaku

Taper tension yifanele ku amukeriwa, hakatsongotsongo kuhungutiwa ntshikelelo wa nip loko roll diameter yikula, ku sivela ku onhaka ka coated surface kumbe 'transferring' unevenness kusuka eka ti layers tale hansi kuya eka ti layers letinga ekusuhi.

IV. Nkomiso

Precise segmented tension control i nchumu wa nkoka eka ku ringanisela swihlawulekisi swa ntumbuluko swa ti substrates ta PTFE—ku nga friction yale hansi xikan’we naku olova ku creep—na xilaveko xa adhesive layer uniformity. Hiku kongoma yi boha matirhelo yohetelela ya Teflon tape eka switirhisiwa swofana na ku tiya ka mahiselo yale henhla xikan’we na swivumbeko swo humesa.
