I. Incazelo kanye Nezindlela Zokulinganisa Zezinkomba
1. Ingxenye yejeli:
Ingxenye yejeli ibhekisela kumaphesenti amakhulu enethiwekhi exhunywe ku-silicone ezwela ukucindezela okunamathelayo enamathiselwe phezu kwayo. Itheyiphu ye-Teflon yokushisa ephezulu engancibiliki kuzincibilikisi ezinhle (njenge-toluene). Inqubo yokulinganisa ihilela ukugoqa ifilimu yokunamathisela ehlanzekile enezikhala zokuhlunga, ukuyikhipha ku-Soxhlet extractor amahora angu-24, bese ukomisa insalela engancibiliki esisindweni esingaguquki ngaphambi kokubala.
2. Amandla ahlangene:
Kuteyiphu ye-Teflon, amandla ahlangene abonakala ngamandla abamba izinga lokushisa eliphezulu (izinga lokushisa lokunamathela kwe-shear noma isikhathi sokubamba i-shear). Ukuhlolwa ngokuvamile kwenziwa ku-180 ° C ngaphansi komthwalo we-1 kg, ukurekhoda isikhathi kuze kube yilapho ungqimba lokunamathisela lushelela noma lwehluleke. Leli nani libonisa ngokuqondile ikhono lesendlalelo sokunamathisela ukumelana nokugeleza nokuhlukana.
II. Ukuxhumana Okuningi Phakathi Kwengxenyana Yejeli namandla Ahlangene
1. Ngaphansi kwephuzu elibalulekile (ingxenye yejeli <60%):
Isistimu ayikakhi inethiwekhi ye-percolating; ungqimba olunamathelayo luhlala lusesimweni sokugeleza kwe-viscous, lunamandla okubamba asondela ku-zero futhi awekho amandla asebenzayo ahlangene.
2. Ibanga elisebenzayo (60%–85%):
Ngale kwephuzu elibalulekile, ukuminyana kweketango elinwebekayo elisebenzayo likhuphuka kakhulu ngengxenye yejeli, futhi amandla ahlangene akhula kakhulu noma alandela umthetho wamandla aphezulu. Ukwandisa ingxenye yejeli kusuka ku-60% kuya ku-70% kungaphakamisa isikhathi sokubamba izinga lokushisa eliphezulu ukusuka emaminithini kuya emahoreni; kusuka ku-70% kuya ku-80%, amandla okubamba angakhuphuka ngezinye izikhathi ezi-3 kuye kweziyi-10. Imodi yokwehluleka ishintsha kancane kancane ukusuka ekwehlulekeni okuhlangene okubanzi kuye kokwehluleka okuxubile.
3. Ibanga eliphezulu lokuxhumanisa (> 85%):
Ukwanda kwamandla ahlangene kunciphisa. Ukuphakamisa ingxenye yejeli isuka ku-85% iye ku-95% kwandisa isikhathi sokubamba ngo-20%–50% kuphela, kodwa i-tack (ukunamathela kokuqala) kwehla kakhulu ngenxa yokuvinjelwa ukuhamba kweketango lamangqamuzana. Lapho ingxenye yejeli idlula ama-95%, ungqimba olunamathelayo lusondela esimweni se-elastomer esihlanzekile, futhi izakhiwo zokunamathela ezizwela ukucindezela ziyalahleka.
III. Imodeli Ye-Semi-Empirical kanye Nedatha Ejwayelekile
Njengoba kufingqiwe abakhiqizi bendwangu ye-Jiangsu Teflon yezinga lokushisa eliphezulu, ubudlelwano obunamandla phakathi kwesikhathi sokubamba i-shear (t_shear) nengxenye yejeli (g) bungavezwa kanje:
lg(t_shear) = A + B · g (no-B cishe u-0.1–0.2), okubonisa ukuncika okubonakalayo. Amanani ka-A no-B ancike esilinganisweni se-MQ resin, ukujiya kongqimba olunamathelayo, nezinga lokushisa lokuhlola.
Idatha evamile ehambisanayo (i-180 °C yokugunda okumile, ejwayele ukubamba isikhathi esingu-1 ku-65% wengxenye yejeli):
| Isiqephu seGel | Isikhathi Sokubamba Isihlobo | Imodi Yokuhluleka |
|--------------------------------------|---------------|
| 55% | < 0.1 | 100% ukwehluleka kokubumbana |
| 65% | 1 | ~80% ukuhluleka kokubumbana |
| 75% | 8-15 | Ukwehluleka okuxubile |
| 85% | 50–100 | Izinsalela ezincane |
| 92% | 150–200 (eduze kokugcwala) | Ukwehluleka okuhlanzekile kokuhlangana kobuso |
Kusobala ukuthi ku-60% -90% ububanzi, njalo ngamaphesenti angu-5 ukwenyuka kwengxenye yejeli kungaholela ekukhuphukeni okuphindaphindiwe kwamandla okuhlangana okuphezulu kwezinga lokushisa.
IV. Lawula Amasu ku-Teflon Tape Manufacturing
1. Ibanga lefraction yejeli eliqondiwe:
Kumateyipu asontayo angangeni ekushiseni enhloso evamile avela kubakhiqizi bendwangu bezinga lokushisa eliphezulu le-Jiangsu Teflon, ingxenyenamba yejeli enconyiwe ingu-75%–85%, i-balance tack kanye nokuhlangana. Ukuze uthole amabhande okuthutha ama-anti-stick aphezulu (kuncike ekulayisheni isikhathi eside ku-200-260 ° C), ingxenye yejeli kufanele ifinyelele ku-85% -93% ukuvimbela izinsalela zokunamathela ezibangelwa ukuhlukaniswa okuhlangene kwesendlalelo sokunamathisela.
2. Izidingo zokufanisa isixhumi esibonakalayo:
I-PTFE surface ye-Teflon high-temperature tape inamandla angaphezulu aphansi kakhulu; ngakho-ke, amandla ahlangene we-adhesive layer kumele abe phezulu kunamandla okunamathela okuhlangene; ngaphandle kwalokho, ukwehluleka okuhlangene kuzokwenzeka ngaphansi kokucindezeleka. Uma ingxenye yejeli idlula ama-93%, ungqimba olunamathelayo luba lukhuni, lunciphise ukumanzisa nokuvumelana ne-PTFE substrate, okungase kuholele ekuphakamiseni unqenqema. Ekukhiqizeni, kubalulekile ukulawula ngokunembile izinga lokushisa elihlanganayo, isikhathi, kanye nemithamo ye-catalyst ukuze ukhiye ingxenye yejeli phakathi kwebanga eliqondiwe, ukuzuza uguquko olunokwethenjelwa ukusuka ekuhlulekeni kokuhlangana ukuya ekuhlulekeni kokuhlangana kobuso.
