Kodi kutentha kwa kuwonongeka ndi theka la moyo wa mankhwala ophatikizira peroxide ziyenera kufananizidwa bwanji ndi zenera la machiritso a tepi ya Teflon?

I. Core Data: Half-Life Parameters ya BPO ndi DCP

1. Half-Life Temperature Reference

Peroxide crosslinking agents amatsata njira zowola zoyambira, ndi theka la moyo (t₁/₂) pa kutentha komwe kumagwiritsidwa ntchito nthawi zambiri.

Benzoyl Peroxide (BPO): 1-minute theka la moyo pafupifupi. 131 ° C, 1 ola theka moyo pafupifupi. 92 ° C, theka la moyo wa maola 10 pafupifupi. 72°C. Kuwola mwazinthu ndi CO₂ ndi benzoic acid, zomwe zimatha kuyambitsa thovu.

2. Dicumyl Peroxide (DCP):

-1-minute theka la moyo pafupifupi. 171 ° C, 1 ola theka moyo pafupifupi. 135 ° C, theka la moyo wa maola 10 pafupifupi. 115 ° C. Zopangidwa ndi acetophenone ndi methane, zokhala ndi fungo lamphamvu.

3. Chofunikira pakugwiritsa Ntchito Data

Miyezo yomwe ili pamwambapa ndi data yazinthu zenizeni. M'mayankho enieni omatira, zosungunulira, zodzaza, ndi ma antioxidants zimatha kusokoneza kuchuluka kwa kuwonongeka, kotero kuwongolera kudzera muyeso wa DSC (Differential Scanning Calorimetry) ndikofunikira.

II. Logic yofananiza Zenera la Njira

1. Dziwani Nthawi Motengera Kuchuluka kwa Kuwola

Zomatira zomatira ziyenera kukwaniritsa 97% -99% crosslinking (pafupifupi 5-7 theka la miyoyo). Choncho, machiritso nthawi ayenera 5-7 nthawi theka la moyo pa chandamale kutentha.

2. Kumbuyo-Kuwerengera Kutentha kuchokera ku Production Line Residence Time

Ngati nthawi yotentha yotentha mu uvuni ndi maminiti a 5 ndipo 5 theka la miyoyo ikufunika kuti amalize, ndiye kuti t₁/₂ ≤ 1 miniti yofunikira. Kutentha kwa theka la moyo wa mphindi imodzi ndi pafupifupi. 131 ° C kwa BPO ndi pafupifupi. 171 ° C kwa DCP. Kutentha kochiritsira kuyenera kukhazikitsidwa kapena kupitirira pang'ono mtengo uwu.

3. Back-Yerekezerani Nthawi kuchokera pa Maximum Allowable Temperature

Choyamba dziwani kutentha kwakukulu (Tmax) komwe gawo lapansi ndi zomatira zimatha kupirira. Pezani theka la moyo pa kutentha, ndiye kuwerengera osachepera okhala nthawi kuchulukitsa ndi 5-7 zina, kuteteza matenthedwe kuwonongeka kwa kutenthedwa.

III. Mawindo Odziwika Ochiritsa a Teflon Tape

Gawo laling'ono la Teflon limakana kutentha kwambiri, koma zomatira za silicone zomwe zimagwiritsidwa ntchito ndizomwe zimalepheretsa. Njira ziwiri zimaperekedwa kutengera mawonekedwe a crosslinker.

1. BPO Low-Temperature Fast Scheme

Oyenera matepi owonda kapena mapulogalamu okhudzidwa ndi kutentha. Zenera: 115-135 ° C, 3-10 mphindi.

Chitsanzo: Pa 125 ° C mu uvuni, theka la moyo wa BPO ndi pafupifupi. Mphindi 2.5, kotero 5 theka miyoyo imatenga pafupifupi mphindi 12.5. Kuti mufulumire, kutentha kumatha kukwezedwa ku 135 ° C (t₁/₂ ≈ masekondi 45), pomaliza ndondomekoyi mu maminiti a 5. Komabe, chidwi chiyenera kuperekedwa ku CO₂ micro-bubble issues; Kutentha kwapang'onopang'ono kapena zodzigudubuza zapakati zimalimbikitsidwa.

2. DCP High-Temperature Stable Scheme

Oyenera matepi wandiweyani ndi zinthu zomwe zimafuna mphamvu yogwira kwambiri yotentha kwambiri. Zenera: 150-175 ° C, 5-15 mphindi.

Chitsanzo: Pa 160 ° C, theka la moyo wa DCP ndi pafupifupi. Mphindi 1.5, kotero 5 theka miyoyo amafuna 7.5 mphindi. Kukwera mpaka 170 ° C kumachepetsa theka la moyo kukhala pafupifupi. Mphindi 0.8, kukwaniritsa kuwonongeka kwa 97% mu mphindi 5, kufananiza mizere yothamanga kwambiri. PTFE ndi yokhazikika pa kutentha uku, kupangitsa izi kukhala zenera labwino la mafakitale.

IV. Mfundo Zofunika Zofananira

1. Kugwirizana Pakati pa Kutentha Kwambiri ndi Kuwonongeka kwa Makhalidwe

Gwiritsani ntchito gradient ya 'kuyambitsa kutentha pang'ono → kutentha kwapamwamba kwambiri.' Mwachitsanzo, ndi DCP, choyamba lolani zomatira kuyenda ndikunyowetsa PTFE pa 130 ° C, kenaka kwezani kutentha kufika 165 ° C kuti mumalize kuchiritsa. Izi zimachepetsa kuwonongeka kwa pamwamba ndikuwonjezera anangula.

2. Deta ya Half-Moyo Iyenera Kuyesedwa Kuti Ikhale Yeniyeni

Zoletsa kapena zosungunulira pakupanga zomatira zimatha kusintha kuchuluka kwa kuwonongeka. Gwiritsani ntchito DSC kuyeza ma curve exothermic curve, pezani nthawi yofikira pamlingo wokulirapo pa kutentha kwa ndondomekoyi, ndikuwerengeranso theka la moyo wofananawo. Musamangotengera mfundo za makhalidwe abwino.

3. Kuganizira za Substrate Thermal History

Kanema wa Teflon wopangidwa ndi mawonekedwe otambasula amatha kutsika kutentha kuposa 200 ° C. Ngati mukugwiritsa ntchito zenera la kutentha kwapamwamba la DCP, gawo lapansi liyenera kusungidwa kale kapena filimu yotsika kwambiri iyenera kusankhidwa kuti muteteze kupiringa kwa tepi pambuyo pochiritsa.

Mwachidule: Malingana ndi nthawi yeniyeni ya kutentha kwa mzere wopangira, sankhani kutentha komwe theka la moyo limakhutiritsa 'n × theka la moyo ≈ nthawi yokhalamo, ' motero kufananiza bwino makhalidwe a kuwonongeka kwa BPO kapena DCP ku njira yochiritsira ya tepi ya Teflon.

Zomwe zili pamwambazi zimaperekedwa ndi Jiangsu OK New Material Technology Co., Ltd. , wopanga nsalu za Teflon zotentha kwambiri.

Ngati mukufuna kudziwa zambiri zatsatanetsatane, mawonekedwe ogwiritsira ntchito, ndi zosankha makonda pazogulitsa zathu zonse, kuphatikiza nsalu za Teflon zotentha kwambiri, tepi yotentha kwambiri ya Teflon, malamba amtundu wa Teflon, malamba osakanizika, malamba amtundu umodzi wa PTFE, nsalu yotentha kwambiri ya fiberglass, magalasi apamwamba kwambiri nsalu-chonde omasuka kulankhula nafe kudzera:

Nambala Yothandizira:  

 

  

Nthawi zonse timatsatira nzeru zaukatswiri woyendetsedwa ndi kukhulupirika, ndipo tadzipereka kukupatsirani mayankho okhazikika komanso ntchito yachidwi!
