Iyini imiphumela yokulawulwa kwe-web tension ngesikhathi senqubo yokumboza ye-Teflon high-temperature tape ku-flatness ye-PTFE substrate kanye nokufana kwe-adhesive coating?

I. Imithelela Ekukhanyeni Kwe-PTFE Substrate

1. Ukwelula Kwepulasitiki kanye 'Necking' Effect

Izinto ze-PTFE zinemoduli enwebekayo ephansi. Uma ukungezwani kweqe umkhawulo wokunwebeka, ukwelula kwepulasitiki okungenakuhlehliswa kwenzeka, okuholela ekwelulweni kwe-longitudinal kanye nokuncipha okuphambene. Ngemuva kokukhishwa kwengcindezi, i-substrate ayikwazi ukubuyela esimweni sayo sokuqala, okuholela ekuxega, imibimbi ye-longitudinal, nokuqina okungalingani. Ezimweni ezinzima, amaphethini we-wavy angashintshana.

2. Ukunqwabelana (Ukugeleza Okubandayo) Ngokuhamba kwesikhathi

I-PTFE idlula ukugeleza kwepulasitiki okunensayo ngaphansi kwengcindezi eqhubekayo. Phakathi nenqubo yokumboza, i-substrate iyathambisa lapho ishisa ngaphakathi kuhhavini omisiwe, futhi ukukhasa kuyaqina. Lokhu kuphakama okungalingani kuba 'iqhwa' ngemva kokupholisa, okuholela ekungalinganini kwendawo noma ama-longitudinal ridges, angeke aqedwe yizinqubo ezilandelayo.

3. I-Uneven Transverse Tension

Ukufana okungalungile kwamarola angumhlahlandlela noma inkomba engalungile yonqenqema kungabangela ukungezwani phakathi kwamaphethelo nendawo, okuholela 'ekugcineni okusontekile,' amabhamuza amaphakathi, noma i-warping ohlangothini olulodwa. Ukushintshashintshashintsha kwezikhathi ezithile kungase kuveze 'amamaki axegayo' aguquguqukayo endaweni engaphansi, okufaka engcupheni ukucaba.

II. Imiphumela Yokufana Kokunamathela Kwesendlalelo Esinamathelayo

1. Ukushintshashintsha Kwezinto Eziqinile Kushintsha Igebe Lokumboza

Embotsheni ye-knife-over-roll, ukungezwani kunquma ngokuqondile izinga lokuxhumana phakathi kwe-substrate ne-blade kadokotela. Lapho ukungezwani kukhula ngokuzumayo, i-substrate icindezelwa kakhulu, inciphisa isisindo sokugqoka; lapho ukungezwani kuncipha, i-substrate iyancipha, ikhulise isisindo sokugqoka. Ukushintshashintsha okunjalo kudala ukuhlukahluka kwezikhathi ezithile kugqinsi lwesendlalelo sokunamathisela eduze kwendlela yewebhu, okwaziwa ngokuthi 'imigqa enqamulayo' noma 'izimpawu zedube.'

2. Ukwelula I-Substrate Kuthinta Ukusatshalaliswa Kwezinto Ezinamathelayo

Ukushuba okweqile kwenza ifilimu ye-PTFE ibe mncane futhi ikhiqize imibimbi emincane, ebese iphindaphindwa ngokunamathela okunamathelayo endaweni engalingani ye-substrate. Ngemuva kokukhishwa kwengcindezi futhi ifilimu ihlehla, ungqimba olunamathelayo lungase lube nemifantu emincane ngenxa yengcindezi engalingani. Kuma-substrates endwangu ye-fiberglass, ukungezwani okweqile kukhulisa izintambo zentambo, kubangele ukungena okunamathelayo okweqile, ukugcinwa okwanele kwendawo, kanye nendawo enamathelayo emagebhugebhu.

3. Imiphumela Ehlanganisiwe Ngesikhathi Sokushisa Nokomisa

I-PTFE ine-coefficient ephezulu yokwandisa okushisayo. Ngaphakathi kuhhavini okomisa, uma izilungiselelo ze-multi-zone tension zingafani, i-substrate ethambile yokushisa idlula okwesibili, ihlanekezela ungqimba olunamathelisa olumanzi kanye nalo, okuholela ekuhlanganiseni okuncane futhi okungalingani ngemva kokumisa. Ukungezwani okungafanele endaweni yokupholisa kungase futhi kubangele ukuncipha kwemibimbi ongqimbeni olunamathelayo olungenawo ukoma.

III. Amasu okulawula abalulekile

1. Izingxenye Zokuqaqa kanye Nezokumboza

Ukucindezeleka okuphansi kakhulu nokuqhubekayo kufanele kusetshenziswe, okwanele nje ukuvimbela i-substrate ekushwabeni, ukuyivumela ukuthi ingene endaweni yokumboza esimweni semvelo futhi igweme ukwelula kwangaphambili.

2. Izigaba Zokomisa Nokupholisa

Ukucushwa okunembile okunembile ngamarola antantayo kufanele kusetshenziselwe ukunxephezela ngokuqhubekayo ukunwetshwa okushisayo nokufinyela kwe-substrate, futhi ukungezwani okuphezulu ezindaweni ezinezinga lokushisa eliphezulu kufanele kugwenywe ngokuqinile.

3. Isigaba Sokubuyisela emuva

I-taper tension kumele yamukelwe, yehlise kancane kancane ingcindezi ye-nip njengoba ububanzi be-roll ikhula, ukuvimbela ukulimaza indawo emboziwe noma 'ukudlulisa' ukungalingani kusuka kumaleya angaphansi kuya kumaleya aseduze.

IV. Isifinyezo

Ukulawula ukushuba kwezigaba okunembe kuyisici esiyinhloko sokulinganisa izici ezingokwemvelo zama-substrates e-PTFE—okungukuthi ukungqubuzana okuphansi nokuba sengozini yokukhukhuleka—nemfuneko yokufana kwesendlalelo sokunamathela. Inquma ngokuqondile ukusebenza kokugcina kwe-Teflon tape kuzinhlelo zokusebenza ezifana nokumelana nokushisa okuphezulu kanye nezakhiwo zokukhululwa.
