I. Tsanangudzo uye Kuyera Nzira dzeZviratidzo 1. Gel chikamu: Iyo gel chikamu chinoreva huwandu hwehuwandu hweiyo crosslinked network mune iyo silicone pressure-sensitive adhesive yakavharwa pamusoro. Teflon high-temperature tepi iyo isinganyunguriki mune zvakanaka zvinonyungudutsa (senge toluene). Iyo yekuyera maitiro inosanganisira kuputira yakachena adhesive firimu mune sefa mesh, kuiburitsa muSoxhlet extractor kwemaawa makumi maviri nemana, uyezve kuomesa iyo isinganyungudika yakasara kune uremu hwenguva dzose usati waverenga.
2. Kubatana simba: MuTeflon tepi, kusimba kwakabatana kunoratidzwa nepamusoro-tembiricha yekubata simba (shear adhesion kutadza tembiricha kana shear kubata nguva). Muedzo unowanzoitwa pa180 ° C pasi pemutoro we1 kg, kurekodha nguva kusvika iyo yekunamatira layer yatsvedza kana kutadza. Kukosha uku kunoratidza zvakananga kugona kweadhesive layer yekuramba kuyerera uye kupatsanura.
II. Quantitative Correspondence Pakati peGel Fraction uye Cohesive Strength 1. Pazasi penzvimbo yakakosha (chikamu chegel <60%): Iyo system haisati yagadzira network ye percolating; iyo inonamira layer inoramba iri mu viscous-flow state, iine simba rakabata rinosvika zero uye pasina rinoshanda rakabatana simba.
2. Hurukuro hunoshanda (60%–85%): Kupfuura iyo yakakosha pfungwa, iyo inoshanda elastic cheni density inowedzera zvakanyanya nechikamu chegel, uye kusimba kwakabatana kunokura zvakanyanya kana kutevedzera mutemo wesimba repamusoro. Kuwedzera chikamu che gel kubva ku60% kusvika ku70% kunogona kusimudza nguva yakakwirira yekubata nguva kubva pamaminitsi kusvika kumaawa; kubva 70% kusvika 80%, simba rekubata rinogona kuwedzera nekuwedzera 3 kusvika ku10 nguva. Iyo yekukundikana modhi zvishoma nezvishoma inoshanduka kubva kune yakakura kubatanidzwa kukundikana kuenda kune yakasanganiswa kukanganisa.
3. High crosslinking range (> 85%): Kuwedzera kwesimba rakabatana kunononoka. Kusimudza chikamu chegel kubva ku85% kusvika ku95% kunowedzera kubata nguva ne20% -50% chete, asi tack (yekutanga adhesion) inodonha zvakanyanya nekuda kwekurambidzwa kwema molecular cheni kufamba. Kana chikamu chegel chinodarika 95%, iyo inonamira layer inosvika kune yakachena elastomer state, uye kudzvanywa-sensitive adhesive zvimiro zvinorasika.
III. Semi-Empirical Model uye Typical Data Sekupfupikiswa naJiangsu Teflon vanogadzira machira epamusoro-tembiricha, hukama hwesimba pakati peshear kubata nguva (t_shear) nechikamu chegel (g) chinogona kuratidzwa se:
Lg(t_shear) = A + B · g (ine B ingangoita 0.1–0.2), zvichiratidza kutsamira kweexponential. Hukoshi hweA neB hunoenderana neMQ resin ratio, adhesive layer ukobvu, uye tembiricha yekuyedza.
Yakajairika data inoenderana (180 °C static shear, yakajairwa kusvika kunguva yekubata ye1 pa65% chikamu chegel):
| Gel Fraction | Relative Holding Time | Failure Mode |
|-------------------------------------------------------|
| 55% | < 0.1 | 100% yakabatana kukundikana |
| 65% | 1 | ~ 80% kutadza kwakabatana |
| 75% | 8–15 | Mixed failure |
| 85% | 50–100 | Zvishoma zvakasara |
| 92% | 150–200 (pedyo nesaturation) | Pure interfacial failure |
Zviri pachena kuti muhuwandu hwe60% -90%, imwe neimwe ye5 muzana-yekuwedzera muchikamu chegel inogona kutungamirira kukuwedzera-kuwedzerwa kwepamusoro-kupisa kwekubatana kwesimba.
IV. Kudzora Strategies muTeflon Tape Manufacturing 1. Target gel chikamu chikamu: Kune akajairwa-chinangwa-anodzivirira kupisa-anotenderedza matepi kubva kuJiangsu Teflon epamusoro-tembiricha anogadzira machira, inokurudzirwa gel chikamu i75% -85%, balancing tack uye kubatana. Kune mabhanhire ekupisa anodzivirira tsvimbo (zvichienderana nekureba kwenguva refu pa 200-260 ° C), chikamu chegel chinofanira kusvika 85% -93% kudzivirira zvakasara zvakanamatira zvinokonzerwa nekubatana kwakabatana kwekunamatira.
2. Interface inoenderana zvinodiwa: Iyo PTFE pamusoro peTeflon yakakwirira-tembiricha tepi ine yakanyanya kuderera pamusoro pesimba; saka, kusimba kwakabatana kweiyo adhesive layer inofanira kunge yakakwira kupfuura iyo interfacial adhesion simba; kana zvisina kudaro, kukundikana kwakabatana kuchaitika pasi pekunetseka. Kana chikamu chegel chinopfuura 93%, chigadziko chekunamatira chinova chakasimba, kuderedza kunyorova uye kuenderana nePTFE substrate, iyo inogona kutungamirira kumucheto kusimudza. Mukugadzira, zvakakosha kuti unyatso kudzora tembiricha yekuyambuka, nguva, uye catalyst dosage kukiya chikamu chegel mukati meyero yakatarwa, uchiwana shanduko yakavimbika kubva mukutadza kwakabatana kusvika pakutadza kwechiso.
