I-Thermal Expansion Coefficient ye-PTFE High Temperature Fabric

I-Jiangsu Aokai New Materials, umkhiqizi ochwepheshe wendwangu yokushisa ephezulu ye-PTFE, ikulethela ulwazi lobungcweti ngale ndlela elandelayo:

I-coefficient yokwandisa okushisayo yendwangu ye-PTFE yokushisa okuphezulu ayilona ivelu egxilile. Ihlala iphansi uma kuqhathaniswa nezinga lokushisa lasekamelweni ukuya ku-100°C (cishe u-0.5×10⁻⁵/°C), nokho ikhuphuka kakhulu ngaphansi kwezimo zokushisa eziphezulu.

1. Idatha ye-Reference Yokunweba Okushisayo ye-PTFE ehlanzekile

Ithebula elingezansi libala ama-coefficients okunweba okushisayo kwe-PTFE emsulwa ngaphansi kwezimo ezihlukene zokuhlola, iyunithi: ×10⁻⁵/°C. Qaphela ukuthi indwangu yokushisa ephezulu ye-PTFE iyinhlanganisela yezinto, futhi izici zayo zizonke zihlobene eduze ne-glass fibre substrate. Idatha elandelayo ikhombisa ikakhulukazi izici ze-PTFE ehlanzekile.

 

Incazelo Yedatha : I-PTFE ibonisa i-anisotropy encane ekwandiseni okushisayo. Amanani ayahluka kancane ngebanga lezinto ezibonakalayo nezinga lokuhlola.

2. Izimiso Ezisebenzayo Nokubaluleka Kwesicelo Esisebenzayo

●  Isimiso sokuwohloka kwe-thermal ephansi : Ukusebenza okunwetshiwe okuphansi kubonakala ngokuhlanganyela ngembongolo ye-PTFE yangaphandle kanye nendwangu yangaphakathi yengilazi enamandla aphezulu. I-Glass fiber ihlanganisa i-ultra-low-low-thermal expansion coefficient engaba ngu-0.5×10⁻⁵/°C, evimbela ngempumelelo kukonke ukunwetshwa nokufinyela kwe-thermal.

●  Umthelela wezinga lokushisa ongaqondile : Ushintsho oluncane lwe-PTFE lukhuphuka ngokusobala ngokunyuka kwezinga lokushisa. Isibonelo, i-PTFE eyimitha engu-1 ehlanzekile izokhula ngo-1.2 mm uma ishisiswe isuka ku-20°C iye ku-120°C, futhi ubude bokunweba bungafinyelela ku-6.5 mm uma ishiswa kufika ku-320°C. Ngaphandle kwalokho, i-PTFE inendawo yoshintsho ezungeze u-23°C, lapho izinga layo lokushintsha kobukhulu likhuphuka ngokushesha, elidinga ukunakwa okukhethekile ekusetshenzisweni kwezimboni ezinembayo.

●   Imfuneko yenqubo yokukhiqiza : Ukushisisa okunganensa nokufanayo kuyadingeka ngesikhathi sokukhiqiza ukuze kulinganiswe umehluko omkhulu wokunweba okushisayo phakathi kwendwangu ye-PTFE nengilazi ye-fiber base fabric, ukugwema ukuqhekeka kokumboza nokubhayiza okubangelwa ingcindezi yangaphakathi.

Sengiphetha, ukunwetshwa okushisayo okuphansi kuyinzuzo eyinhloko yendwangu yokushisa ephezulu ye-PTFE, kuyilapho umthamo wayo wangempela wokunweba ukhuphuka ngokungahambisani nezinga lokushisa. Idatha ye-coefficient ehambisanayo izotholwa ukuze ibalwe ngokuya ngezinga lokushisa langempela lokusebenza kumklamo wohlelo lokusebenza onezinga lokushisa eliphezulu.

Ulwazi lobuchwepheshe olungenhla lunikezwe i- Jiangsu Aokai New Materials Technology Co., Ltd.

Sihlinzeka ngemikhiqizo egcwele uhla oluhlanganisa i-PTFE izinga lokushisa eliphakeme lendwangu, PTFE itheyipu enamathelayo enezinga eliphezulu lokushisa, ibhande le-PTFE elinenetha, ibhande lomshini wokuhlanganisa elingenamthungo, indwangu ye-PTFE enohlangothi olulodwa, ibhande lokudlulisa elimelana nokushisa okuphezulu nendwangu yengilazi engashi. Sihlinzeka ngemingcele yezobuchwepheshe enemininingwane, izixazululo zohlelo lokusebenza kanye nezinsizakalo ezenziwe ngezifiso.
