I. Kɔr Data: Haf-Layf Paramita dɛn fɔ BPO ɛn DCP

1. Haf-Layf Tɛmpratura Rifrɛns

di pεrכksayd kכroslinkin ejen dεm de fala fכs כda dεkכmכshכn kεnεtiks, wit di haf-layf (t1/2) na wan givεn tεmprachכ we na di indikεtכ we dεn kin yus kכmכn.

Benzoyl Peroxide (BPO): 1 minit haf-layf na aprɔks. 131°C, 1-awa haf-layf na aprɔks. 92°C, 10 awa haf-layf na lɛk. 72°C. di kכmכshכn bay-prכdukt dεm na CO2 εn bεnzoik asid, we kin izi fכ mek bכbul.

2. Dikumil Pɛroksayd (DCP): .

-1-minit haf-layf na aprɔks. 171°C, 1-awa haf-layf na aprɔks. 135°C, 10 awa haf-layf na lɛk. 115°C. Di tin dɛn we dɛn kin yuz fɔ mek tin dɛn na asetofinɔn ɛn mitin, we kin smɛl smɔl.

3. Di tin we yu fɔ du bifo yu yuz di Data

Di valyu dεm we de oba na rεfrεns data fכ klin sכbstans dεm. insay aktual adhesive sכlushכn, sכlvεnt, fil, εn antioksidant kin intafεr wit di dεkכmכshכn rεt, so kכrekshכn via DSC (Differential Scanning Calorimetry) mεzhɔmεnt nid fכ.

II. Lɔjik fɔ Match di Prɔses Windo

1. Ditarmin di Tɛm Bays pan di Digri we di Dikɔmpɔzishɔn de

di adhesive layεr nid fכ achy 97%–99% kכroslink (aprכksimatli 5–7 haf-layf). fכ dat, di tεm we i de kכl fכ bi 5–7 tεm di haf-layf na di tεmprachכ we dεn tכk bכt.

2. Bak-Kalkul Tɛmpratura frɔm Prodakshɔn Layn Residɛns Taym

If di ifektiv hεt tεm na di כvin na 5 minit εn 5 haf-layf nid fכ komplit, den di t1/2 ≤ 1 minit we nid. Di 1 minit haf layf tɛmpracha na lɛk. 131°C fɔ BPO ɛn lɛk. 171°C fɔ DCP. di tεmprachכ fכ kכriכn fכ set na כ sכmtεm oba dis valyu.

3. Bak-Kalkul Taym frɔm Maksimal Alawable Tɛmpratura

Fɔs disayd di maksimal tɛmpracha (Tmax) we di sabstret ɛn adhesive layt kin bia. Fɛn di haf-layf na da tɛmpracha de, dɔn kɔl di minim rɛsidɛns tɛm bay we yu multiply bay 5–7 tɛm, fɔ mek di tɛmral damej nɔ ɔva ɔt.

III. Tipik Curing Windo fɔ Teflon Tep

Di Teflon sabstret gɛt fayn fayn ɔt rɛsistɛns, bɔt di silikon prɛshɔn-sɛnsitiv adhesive we dɛn aplay na di limitin factor. Tu skim dεm dεn prכpos bays pan di kכroslinkεr kכntribyushכn dεm.

1. BPO Lɔw-Tɛmpratura Fast Skim

I fayn fɔ tin tep ɔ aplikeshɔn dɛn we sɛnsitiv to ɔt shrinkage. Windo: 115–135°C, 3–10 minit.

Example: Na 125°C insay di oven, di BPO haf-layf na aprɔx. 2.5 minit, so 5 haf layf tek lɛk 12.5 minit. fכ mek di tεmprachכ go spid, dεn kin rεs di tεmprachכ to 135°C (t1/2 ≈ 45 sekכnd), fכ komplit di prכsεs insay 5 minit. Bɔt dɛn fɔ pe atɛnshɔn to CO2 maykro-bɔbul ishu dɛm; step hεtin כ intamεdiεt nip rכla dεm dεn rεkomεnd.

2. DCP Ay-Tɛmpratura Stebul Skim

I fayn fɔ tik tep ɛn prɔdak dɛn we nid fayn fayn ay-tɛmpracha fɔ ol pawa. Windo: 150–175°C, 5–15 minit.

εgzampl: Na 160°C, di DCP haf-layf na aprכx. 1.5 minit, so 5 haf-layf nid 7.5 minit. we yu rayz to 170°C i de ridyus di haf-layf to aprכx. 0.8 minit, we de ajɔst ova 97% dikɔmpɔzishɔn insay 5 minit, we de mach di ay-spid prodakshɔn layn dɛn.

IV. Ki Praktikal Points fɔ Match

1. Sinaji Bitwin Stɛp Hɛt ɛn Dikɔmpɔzishɔn Karakta

Yuz wan gradient we na 'lɔ-tɛmpracha initieshɔn → ay-tɛmpracha ful kroslinkin.' Fɔ ɛgzampul, wit DCP, fɔs alaw di adeziv fɔ flɔ ɛn wet di PTFE na 130°C, dɔn rayz di tɛmpracha to 165°C fɔ kɔmplit di kɔring. Dis de ridyus di sɔfayz difrɛns ɛn i de mek di ankɔrej bɛtɛ.

2. Haf-Layf Data fɔ Kalibrayt to di Aktual Fɔmyulashɔn

3. Kɔnsidɛreshɔn fɔ Sabstret Tɛmral Istri

Tεflon film we dεn fכm strεch kin כnda tεmral shrinkεj oba 200°C. If yu de yuz di DCP ay-tɛmpracha winda, di sabstret fɔ bi prɛ-annial ɔ yu fɔ pik wan low-shrinkage skived film fɔ mek di tep nɔ kɔl afta i dɔn wɛl.

In sɔmari: Bays pan di aktual ɔt durayshɔn fɔ di prodakshɔn layn, pik wan tɛmpracha pɔynt usay di haf-layf satisfay 'n × af-layf ≈ rɛsidɛns tɛm,' so dat i go prɛsishɔn mach di dikɔmpɔzishɔn kwaliti dɛn fɔ BPO ɔ DCP to di kɔring prɔses fɔ Teflon tep.
