Crosslinking Systems for High-Temperature Silicone Pressure-Sensitive Adhesives: Mitundu ndi Kusiyana

Kutsika kwapamwamba kwa matepi otentha kwambiri a Jiangsu Aokai a Teflon kumatsimikiziridwa ndi njira yolumikizirana ndi machiritso ya zomatira zomata za silicone zomwe zimagwiritsidwa ntchito popaka. Popanga matepi a Teflon otentha kwambiri a Aokai, pali machitidwe awiri akuluakulu: peroxide crosslinking  ndi platinamu-catalyzed kuwonjezera . Machitidwe awiriwa ali ndi chikoka chachikulu pa kukana kutentha, ukhondo ndi kupanga bwino kwa matepi apamwamba a Teflon.

1. Peroxide Crosslinked High-Teflon Teflon Teflon

M'matepi a Teflon oyambilira komanso otenthetsera kwambiri, kuphatikizika kwaulele komwe kumayambitsidwa ndi peroxides kumatengedwa kaŵirikaŵiri. Tepi yamtundu wa Teflon yotentha kwambiri imafuna uvuni wotentha kwambiri kuposa 150 ° C, zomwe zimapangitsa kuti pakhale mphamvu zambiri.

Mawonekedwe Ogwira Ntchito : Matepi otenthetsera kwambiri a Teflon opangidwa pansi pa dongosololi amanyamula zotsalira zazinthu zomwe zimachitika. Pa nthawi yayitali yotentha kwambiri, zomatira zimakhala ndi chiopsezo chochepa cha chikasu, ndipo kukhazikika kwa mphamvu ya peel kumakhala kochepa.

Zochitika Zogwiritsira Ntchito :Matepi a Teflon otentha kwambiri ngati amenewa ndi oyenera kwambiri kugwiritsira ntchito mafakitale odana ndi ndodo komanso ntchito zosindikizira kutentha komwe kulibe zofunikira zapadera zomveka bwino komanso kukhudzidwa kwa mtengo ndizofunika kwambiri.

2. Platinum-Catalyzed Addition High-Teflon Teflon Teflon

Matepi a Teflon okwera kwambiri komanso oyeretsa kwambiri nthawi zambiri amasinthidwa kukhala dongosolo lowonjezera la platinamu-catalyzed hydrosilylation. Izi ndizofunikira kwambiri kwa matepi a Teflon otentha kwambiri omwe amafunikira kuwongolera mphamvu yakutulutsa.

Ubwino Wachikulu :Matepi a Teflon otentha kwambiri omwe amagwiritsa ntchito platinamu amatha kuchiritsidwa mwachangu pa 100-130 ° C, kuwongolera bwino zokutira. Popeza palibe zopangira zomwe zimapangidwa, zomatira ndizoyera komanso zowonekera. Pautumiki wanthawi yayitali pa 260 ° C, zotsalira zotsalira ndizotsika kwambiri, ndipo sizingawononge zida zamagetsi zomangika.

Zolepheretsa Njira :Panthawi yopangira, malo ochitira misonkhano ndi nsalu za Teflon ziyenera kukhala zoyera kwambiri. Kupanda kutero, kufufuza zonyansa kumatha kuwononga mosavuta chothandizira cha platinamu, zomwe zimabweretsa kuchiritsa kosakwanira kapena kutaya kumamatira.

Mwachidule, kaya amagwiritsidwa ntchito pazitsulo zotetezera kutentha kwazitsulo zotsutsana ndi ndodo kapena kukulunga kwa chingwe, kumvetsetsa njira yodutsamo ya silicone yochepetsera kupanikizika kwazitsulo pa matepi a Teflon omwe amatha kutentha kwambiri amatsimikizira mwachindunji ntchito yeniyeni pansi pa ntchito zovuta kwambiri. Kwa masking osamva kutentha, makina opangira peroxide amatha kusankhidwa.

Zambiri pamwambapa zimaperekedwa ndi Jiangsu Aokai New Material Technology Co., Ltd.

Kuti mumve zambiri pamatchulidwe, mawonekedwe ogwiritsira ntchito ndi mayankho makonda pazogulitsa zathu zonse - kuphatikiza PTFE yokutidwa ndi fiberglass nsalu, Teflon high-temperature tepi, PTFE lotseguka mauna lamba conveyor lamba, lamba makina omangira, mbali imodzi PTFE yokutidwa nsalu, mkulu-kutentha wosagwira fiberglass chonde kukhudzana ife chizimba chosagwira nsalu nsalu:

Timakhala ndi malingaliro aukadaulo komanso odalirika pantchito, ndipo tadzipereka kukupatsirani mayankho okhazikika komanso ntchito zachidwi.
