Web tension control (web tension control) bɛ nɔ jumɛn bila Teflon kasɛti funteni caman dacogo la PTFE substrat flakɛli la ani finimugu nɔrɔlen ka kelenya la?

I. A nɔ minnu bɛ PTFE substrat ka flati la

1. Plastiki sɔgɔli ani 'Kɔnɔ' nɔ

PTFE fɛn bɛ ni modulu élastique dɔgɔman ye. Ni jɔrɔnanko tɛmɛna a dan ye min bɛ se ka wuli, plastiki sɔgɔli min tɛ se ka wuli, o bɛ kɛ, o bɛ na ni janya janya ye ani ka dɔgɔya ka tɛmɛ. Jatigɛ bɔra kɔfɛ, substrat tɛ se ka segin a cogo kɔrɔ la, o bɛ na ni sɛgɛn ye, ka kurukuru janya, ani ka kɛ a janya tɛ kelen ye. Ni a juguman don, a bɛ se ka kɛ ko jirisunw bɛ se ka kɛ.

2. Creep (Cold Flow) dalajɛli waati kɔnɔ

PTFE bɛ plastiki boli dɔɔni dɔɔni kɛ ni tension basigilen ye. Datugulan kɛtuma na, substrat bɛ nɔgɔya ni a sumana jalen foro kɔnɔ, wa creep bɛ bonya. O janya bɛnbali in bɛ kɛ 'frozen' ye nɛnɛ kɔfɛ, o bɛ na ni sanfɛla bɛnbaliya ye walima janya-janya, o min tɛ se ka ban ni taabolo nataw ye.

3. Tension transversale (Tension transversal) min tɛ kelen ye

Guide rollers ka paralɛli jugu walima dakun ɲɛminɛbaliya bɛ se ka kɛ sababu ye ka danfara don tensions danfara la dakunw ni cɛmancɛ cɛ, o bɛ na ni 'curled edges,' central blistering, walima single-side warping ye. Tansiyɔn jiginni waati ni waati fana bɛ se ka kɛ sababu ye ka 'tight-loose marks' caman ɲɔgɔn falen-falen kɛ substrat surface kan, ka flatness tiɲɛ.

II. A nɔ minnu bɛ sɔrɔ Coating Uniformity of the Adhesive Layer la

1. Tension Fluctuations bɛ Coating Gap Changer

Knife-over-roll coating (knife-over-roll coating) la, tension bɛ a jira k’a ɲɛsin substrat ni dɔgɔtɔrɔ ka dawolo cɛ ɲɔgɔn sɔrɔli hakɛ ma. Ni tension barika banna, substrat bɛ digi ka taa a fɛ, o bɛ dɔ bɔ finimugu girinya la; ni tension dɔgɔyara, substrat bɛ lajɔ, o bɛ dɔ fara finimugu girinya kan. O jiginni suguw bɛ fɛn caman wuli waati ni waati nɔrɔlenw lamini janya la ɛntɛrinɛti sira fɛ, min bɛ wele ko 'crosswise streaks' walima 'zebra marks.'

2. Substrate Stretching bɛ nɔ bila adhesive jɛnsɛnni na

Ni tension tɛmɛnen bɛ PTFE filimu fin ani ka micro-wrinkles (kurukuru fitininw) lawuli, o kɔfɛ, u bɛ segin ka kɛ ni nɔrɔlen ye min bɛ substrat (yɔrɔ) kan min tɛ kelen ye. Ni tension bɔra ani ka filimu dɔgɔya ka segin kɔ, a nɔrɔlen bɛ se ka micro-cracks sɔrɔ ka a sababu kɛ degun ye min tɛ kelen ye. Fibreglasi finimuguw la, tension kojugu bɛ jiriw cɛmancɛw bonya, o bɛ kɛ sababu ye ka nɔrɔli kɛ ka tɛmɛ a dan kan, ka yɔrɔ minɛ ka ɲɛ, ani ka kɛ sababu ye ka finimugu gɛlɛn kɛ.

3. Fɛn minnu bɛ sɔrɔ ɲɔgɔn fɛ funteni ni jalen waati

PTFE ka coefficient de expansion thermoux ka bon. Jalen foro kɔnɔ, ni zone caman tension settings ma bɛn, substrat min nɔgɔyara ni funteni ye, o bɛ sɛgɛn filanan kɛ, ka nɔrɔlen ɲiginnen tiɲɛ ka fara a kan, o bɛ na ni finimugu finman ye min tɛ kelen ye jalen kɔfɛ. Nɛnɛyɔrɔ tensionbaliya fana bɛ se ka kɛ sababu ye ka sɔgɔsɔgɔninjɛ kɛ nɔrɔlan tilancɛ jalen na.

III. Kɔlɔsili fɛɛrɛ jɔnjɔnw

1. Dakun minnu bɛ fɛnw dabɔ ani ka u datugu

A ka kan ka tension min ka dɔgɔn kosɛbɛ ani min bɛ to ka kɛ, o ka kan ka kɛ dɔrɔn walasa ka substrat bali ka kurukuru, ka a to a ka don finimugu yɔrɔ la a cogo la ani ka a yɛrɛ tanga ka kɔn ka sɔgɔsɔgɔ.

2. Jalen ni nɛnɛ yɔrɔw

Fɛnɲɛnɛma tigitigiw ka kan ka kɛ ni wuluwuluw ye minnu bɛ panpan, walasa ka funteni bonya ni a dɔgɔyali musaka bɔ ni timinandiya ye, wa, a ka kan ka kɔlɔsi kosɛbɛ ka tension (jatigɛ) kɛ funteni caman bɛ yɔrɔ minnu na.

3. Dakun min bɛ segin-ka-bɔ

Taper tension ka kan ka ta, ka nip tansiyɔn dɔgɔya dɔɔni dɔɔni ni roll diameter bɛ bonya, walasa ka a bali ka tiɲɛni kɛ a ɲɛda datugulen na walima 'transferring' unevenness ka bɔ duguma layɛrɛw la ka taa layɛrɛ kɛrɛfɛtaw la.

IV. Farankan

Tansiyɔn kɔlɔsili tilalen tigitigi ye fɛnba ye min bɛ PTFE substrates ka jogo danbew balansi — n’o ye sɔgɔsɔgɔninjɛ dɔgɔyali ye ani sɔgɔsɔgɔninjɛ ka teli ka wuli — ni wajibi ye ka nɔrɔlanw kɛ kelen ye. A bɛ Teflon kaseti baara laban dantigɛ k’a ɲɛsin baarakɛcogo ma i n’a fɔ funteni caman kunbɛnni ani a bɔli cogoya.
