Iyi ngingo ikubiyemo ibipimo ngenderwaho byerekana imikorere ya PTFE yubushyuhe bwo hejuru ikoreshwa mu gutwikira vacuum, kuvura ubushyuhe bwa vacuum hamwe n’ibidukikije bisa. Ibisabwa byingenzi biratandukanye cyane nikoreshwa ryikirere: gusohora ni ngombwa cyane (TML≤1%, CVCM≤0.1%; amanota yo mu kirere / optique bisaba TML≤0.5%, CVCM≤0.01%); ubushyuhe bwo kurwanya ubushyuhe bugomba kugenzurwa kuri substrate ya PTFE (260 ° C) hamwe nigiti gifatika; byumwihariko wasukuwe cyane silicone ya silicone PSA irasabwa gukumira siloxane; ubushyuhe bwo hejuru bufata imbaraga birinda kunyerera no guterura inkombe; isuku isaba nta fibre yamenetse hamwe nibirimo ionic; kaseti irwanya static (irwanya ubuso 10⁶-10⁹ Ω / sq) irinda kwangirika kwa ESD; plasma irwanya igomba gusuzumwa kubikorwa / PECVD; kugabanuka k'ubushyuhe munsi ya 2% byemeza ko masking itomoye.

Iyi ngingo igereranya icyumba-ubushyuhe nubushyuhe bwo hejuru bwo gukura kwa silicone yumuvuduko ukabije wa kaseti ya PTFE. Gukura k'ubushyuhe bwo hejuru (120-180 ° C) bituma habaho imiyoboro ihuza imiyoboro ifite imbaraga zifatika, ikarinda ibisigazwa bifata nyuma yo kuyikuramo. Ikora imiti ihuza imiti hamwe na PTFE ikoresheje primer co-curing, ikuraho ingaruka zo gusiba. Gukura k'ubushyuhe bwo hejuru kandi bikuraho imbaraga za molekile nkeya mbere yo kubyara, bikarinda amavuta menshi ya silicone mugihe cyo gushyushya bwa mbere.

Aka gatabo karimo PTFE yubushyuhe bwo hejuru bwo gutoranya kaseti yo gutera inshinge no kurwanya anti-stick. Guhitamo bishingiye ku bushyuhe: 60260 ° C kuri plastiki rusange (kaseti ya silicone isanzwe ya PSA, 0.13-0.18mm); 260-300 ° C kuri plastiki yubushyuhe bwo hejuru yubushakashatsi nka PC, PA66, POM (yometse hejuru ya tempic silicone, 0.18-0.25mm); 300-400 ° C kuri PEEK, LCP, PPS hafi yiruka ashyushye (kaseti ifata birananirana; koresha umwenda wa PTFE udafite amavuta cyangwa firime ya PFA). Guhitamo bishingiye ku bikoresho: ibikoresho byoroshye bikenera-kurekura hejuru ya PTFE yuzuye; ibirahuri / minerval yuzuye ibikoresho bisaba uburemere-0.25mm + kaseti idashobora kwambara; inyongeramusaruro yangiza isaba imiti irwanya imiti hamwe nubutaka bwuzuye; porogaramu ihamye-ikenera anti-static umukara PTFE kaseti.

Imyenda ya PTFE isize fiberglass ikoreshwa cyane mugutunganya reberi kugirango irwanye ubushyuhe bwayo, umutungo udafite inkoni, hamwe no guterana amagambo. Porogaramu z'ingenzi zirimo: kurekura imirongo ya plate / vacuum vulcanisation no kubumba amapine; imikandara ya convoyeur idakoreshwa kumashini ifunguye, kalendari, n'imirongo ikonjesha; guhuza imyenda yo kubika igice cyarangije kubikwa; uburyo bwihariye bwo gukora silicone na fluororubber; n'itanura ry'itanura ryo gukira. Inyungu zirimo kuvanaho ifumbire mvaruganda, kugabanya imikoreshereze yabashinzwe kurekura, kwirinda kuzinga, no kwemeza neza.

Ubushyuhe bwikirahure (Tg) bwa silicone yumuvuduko ukabije ni -120 ° C - munsi cyane ugereranije na acrylic. Iyi ultra-low Tg ituma PTFE yubushyuhe bwo hejuru ya kaseti ihindagurika kandi ikomera ndetse no kuri -70 ° C, ikarinda gucika intege kandi igafasha kwizerwa mubikorwa bya cryogenic.

Guhitamo impapuro zo gusohora cyangwa firime substrate no kurekura bigira ingaruka itaziguye kububiko no gukuramo imikorere ya PTFE yubushyuhe bwo hejuru. Iyi ngingo igereranya PET na kraft impapuro substrates hamwe na silicone na fluorine yo kurekura, byerekana uburyo bwiza bwo guhuza ibishishwa bya zeru-bisigara kandi byizewe igihe kirekire.
