I. Core Data: Half-Life Parameters yeBPO neDCP
1. Half-Life Temperature Reference
Peroxide crosslinking agents anotevera ekutanga-odha decomposition kinetics, nehafu yehupenyu (t₁/₂) patembiricha yakapihwa ichiva chiratidzo chinowanzoshandiswa.
Benzoyl Peroxide (BPO): 1-miniti hafu yehupenyu pa approx. 131°C, 1-awa hafu yeupenyu panguva approx. 92°C, 10-awa hafu yeupenyu panguva approx. 72°C. Kuora ne-zvigadzirwa ndeye CO₂ uye benzoic acid, iyo inogona kukonzera mabhubhu nyore nyore.
2. Dicumyl Peroxide (DCP):
-1-miniti hafu yehupenyu pane approx. 171°C, 1-awa hafu yeupenyu panguva approx. 135°C, 10-awa hafu yeupenyu panguva approx. 115°C. Zvigadzirwa zvinonzi acetophenone uye methane, ine kunhuhwirira kwakasimba.
3. Chinodiwa paKushandisa Data
Hwaro huri pamusoro apa ndehwe data rezvinhu zvakachena. Mumhinduro chaidzo dzekunamira, zvinonyungudutsa, mafirita, uye antioxidants zvinogona kukanganisa mwero wekuora, saka kururamisa kuburikidza neDSC (Differential Scanning Calorimetry) kuyerwa kunodiwa.
II. Logic yekufananidza iyo process Window
1. Sarudza Nguva Kubva pane Dhigirii reKuora
Iyo yekunamatira layer inoda kuwana 97% -99% crosslinking (inenge 5-7 hafu yeupenyu). Nokudaro, nguva yekurapa inofanira kuva 5-7 nguva yehafu yehupenyu pane chinangwa chekushisa.
2. Kumashure-Karukureta Temperature kubva Production Line Residence Nguva
Kana iyo inoshanda yekupisa nguva muchoto iri 5 maminitsi uye 5 hafu yehupenyu inodiwa kuti ipedze, zvino inodiwa t₁/₂ ≤ 1 miniti. Iyo 1-miniti hafu yehupenyu tembiricha ndeye approx. 131°C yeBPO uye approx. 171°C yeDCP. Iyo tembiricha yekurapa inofanirwa kuiswa pairi kana zvishoma pamusoro pehukoshi uhu.
3. Kudzoka-Kuverenga Nguva kubva kuMaximum Allowable Temperature
Kutanga tarisa iyo yakanyanya tembiricha (Tmax) iyo substrate uye inonamatira layer inogona kumira. Tsvaga hafu yehupenyu pane iyo tembiricha, wobva waverenga iyo shoma yekugara nguva nekuwanda ne5-7 nguva, kudzivirira kukuvara kwekupisa kubva pakupisa.
III. Yakajairika Kurapa Windows yeTeflon Tape
Iyo Teflon substrate ine yakanakisa kupisa kupisa, asi iyo silicone kumanikidza-inonzwa inonamira yakaiswa ndiyo inomisa chinhu. Zvirongwa zviviri zvinotsanangurwa zvichibva pane iyo crosslinker maitiro.
1. BPO Low-Temperature Fast Scheme
Inokodzera matepi matete kana maapplication anonzwa nekupisa shrinkage. Hwindo: 115-135 ° C, 3-10 maminitsi.
Muenzaniso: Pa 125 ° C muchoto, iyo BPO hafu yehupenyu ndeye approx. 2.5 maminetsi, saka 5 hafu-hupenyu hunotora anenge 12.5 maminetsi. Kuti ikurumidze, tembiricha inogona kusimudzwa kusvika 135 ° C (t₁/₂ ≈ 45 seconds), kupedzisa maitiro mumaminitsi mashanu. Nekudaro, kutarisisa kunofanirwa kubhadharwa kune CO₂ micro-bubble nyaya; kutsika kupisa kana yepakati nip rollers inokurudzirwa.
2. DCP High-Temperature Stable Scheme
Inokodzera matepi akakora uye zvigadzirwa zvinoda yakanakisa yepamusoro-tembiricha yekubata simba. Hwindo: 150-175 ° C, 5-15 maminitsi.
Muenzaniso: Pa160 ° C, iyo DCP hafu yehupenyu ndeye approx. 1.5 maminetsi, saka 5 hafu-hupenyu hunoda 7.5 maminetsi. Kusimudza kusvika 170 ° C kunoderedza hafu yehupenyu kusvika approx. 0.8 maminetsi, kuwana pamusoro pe97% kuora mu5 maminetsi, ichienderana neyakakura-kumhanya mitsetse yekugadzira. PTFE inodzikama pane ino tembiricha, ichiita iyi hwindo rakanaka reindasitiri.
IV. Mapoinzi Anoshanda Pakufananidza
1. Synergy Pakati Pekutsika Kupisa uye Kuparara Hunhu
Shandisa gradient ye 'low-temperature initiation → high-temperature full crosslinking.' Semuenzaniso, neDCP, tanga wabvumira kunamira kuyerera uye kunyorovesa PTFE pa130 ° C, wozosimudza tembiricha kusvika 165 ° C kuti ipedze kupora. Izvi zvinoderedza kuremara kwepamusoro uye zvinowedzera anchorage.
Inhibitors kana zvinonyungudutsa mukugadzirwa kwekunamatira zvinogona kuchinja chiyero chekuparara. Shandisa DSC kuyera iyo yekurapa exothermic curve, tsvaga nguva yekusvika pahupamhi hwekuita chiyero pane tembiricha yekushanda, uye kumashure-kuverengera yakaenzana hafu yehupenyu zvinoenderana. Usangotevedzera tsika dzakajairika.
3. Kufunga nezve Substrate Thermal Nhoroondo
Firimu reTeflon rakatambanudzwa rinogona kuita kudzikira kwepamusoro pe200°C. Kana ukashandisa DCP yepamusoro-tembiricha hwindo, iyo substrate inofanira kunge isati yanyura kana yakaderera-shrinkage skived firimu inofanira kusarudzwa kudzivirira tepi curling mushure mekurapa.
Muchidimbu: Kubva pane chaiyo yekupisa nguva yemutsetse wekugadzira, sarudza tembiricha iyo iyo hafu yehupenyu inogutsa 'n × hafu yeupenyu ≈ nguva yekugara,' nokudaro kunyatsoenderana nekuora maitiro eBPO kana DCP kune nzira yekurapa yeTeflon tepi.
Mashoko ari pamusoro apa anopiwa ne Jiangsu OK New Material Technology Co., Ltd. , inogadzira machira eTeflon emhando yepamusoro.
Kana iwe uchida kudzidza zvakawanda pamusoro pezvakatsanangurwa zvakatsanangurwa, mamiriro ekushandisa, uye sarudzo dzekugadzirisa dzemhando yedu yakazara yezvigadzirwa-kusanganisira Teflon yakakwirira-tembiricha machira, Teflon yakakwirira-tembiricha tepi, Teflon yakakwirira-tembiricha mesh mabhandi, seamless anonamira muchina mabhandi, single-sided PTFE jira rekushisa, fibre-temperature yakakwirira machira-ndapota inzwa wakasununguka kutibata nesu kuburikidza:
