Niki Gitera Gucika muri Gahunda yo Kwinjiza PTFE?

Nkumushinga wabigize umwuga ukora PTFE yimyenda yubushyuhe bwo hejuru, Jiangsu Aokai Ibikoresho bishya bizasobanura impamvu zitera kumeneka mumyenda y'ibirahure nyuma yo gutera akabariro hamwe na PTFE (polytetrafluoroethylene). Iki nikibazo gikunze kugaragara mubikorwa byo gukora ibintu, bikunze kugaragara mugihe cyo gukama (kuvanaho ubuhehere na surfactants) cyangwa gucana ubushyuhe bwo hejuru (gushonga ibice bya PTFE muri firime ikomeza).

1. Kudahuza bikabije bya Coefficients yo Kwagura Ubushyuhe

Iyi niyo mpamvu yibanze yumubiri.

Hariho itandukaniro rinini muri coefficient zo kwagura ubushyuhe hagati ya fibre yikirahure na PTFE: coefficente yo kwaguka kumurongo wa fibre yikirahure igera kuri 5 × 10⁻⁶ / ℃ , mugihe iya PTFE igera kuri 100 × 10⁻⁶ / ℃ kugeza 200 × 10⁻⁶ / ℃  (hafi inshuro 20 z'ububiko bw'ikirahure).

Mugihe cyo gukonjesha (uhereye ku bushyuhe bukabije bwa 380 ℃ –400 ℃ kugeza ku cyumba cy'ubushyuhe), PTFE iragabanuka cyane ugereranije n'ikirahuri cya fibre. Kubera ko ikirahuri cya fibre fibre ikora nka skeleti ikomeye, PTFE irabuzwa mugihe cyo kugabanuka, bikabyara impagarara zumuriro imbere. Iyo iyi mihangayiko irenze imbaraga zingana za firime ya PTFE cyangwa imbaraga zo guhuza imiyoboro hagati ya PTFE na fibre yibirahure, gucika bibaho kurekura imihangayiko.

2. Kugenzura nabi uburyo bwo gukama no gucumura

Gushyushya ibipimo byibintu byatewe byatewe no guturika:

·  Igipimo cyinshi cyo gushyuha cyane : Cyane cyane hafi 100 ℃ (guhumeka vuba kwubushuhe) na 200 ℃ –250 ℃ (kubora kwa surfactants muri emulsion na zone yinzibacyuho mbere yo gucumura PTFE). Ubushuhe bwihuse butera guhangayika imbere hamwe na gaze bituruka kumyuka ihita ihindagurika yumuti ninyongeramusaruro, bikaviramo guturika.

·  Igipimo cyihuta cyane cyo gukonjesha : Guhura neza numwuka wibidukikije kugirango ukonje byihuse nyuma yo gucumura bitera guhangayika cyane ako kanya bitewe nubushyuhe bwinshi, butera byoroshye imiyoboro myiza.

·  Ubushyuhe bukabije cyane cyangwa igihe kinini cyo gucumura : Ibi bitera kwangirika kwuburemere bwa molekile ya PTFE hamwe nubwinshi bwamazi, bigatuma ibikoresho byoroha cyane gucika mukibazo.

3. Ibibazo muburyo bwo Kwinjiza no Kwibanda kwa Emulsion

Umubyimba, uburinganire n'ubwuzuzanye bw'uburinganire bwatewe mu buryo butaziguye:

·  Umubyimba mwinshi cyane wo gutera akabariro : Mugukurikirana umubyimba cyangwa gukora neza, igipande cyinshi cyane cya PTFE gikoreshwa mugice kimwe. Mugihe cyo kumisha no gucumura, igifuniko kibyibushye gifite inzira ndende yo gukuraho ibishishwa kandi bigenda bigabanuka cyane (emulioni ya PTFE mubusanzwe ifite ibintu bikomeye bingana na 60%, bivuze ko hafi 40% yubushyuhe igomba kuvaho), ibyo bikaba akenshi bitera kumeneka hejuru.

Gutera  inda kutaringaniye : Kwiyongera kwa PTFE birenze urugero cyangwa gukwirakwiza emulsiyo itaringaniye hejuru yigitambara biganisha kumaganya yo kugabanuka.

·  Kwinjira kwa emulsiyo bidahagije : Niba umwenda wibirahure bya fibre udafite ibishashara cyangwa ngo bivurwe nabi, PTFE emulsiyo ntishobora kunanirwa kwinjira mumigozi ya fibre kandi ikora gusa 'firime y'uruhu '. Iyi firime ifite intege nke hamwe na substrate kandi ikunda gutandukana cyangwa gucika iyo ishyushye.

4. Substrate-Ibintu bifitanye isano

·  Umwenda wibirahure utagira ibishashara : Umwenda wibirahure urimo ibintu bingana (paraffin, epoxy, nibindi) uhereye kububoshyi. Hatabayeho ubushyuhe bwo hejuru cyangwa gusukura imiti mbere yo gutera akabariro, ibyo bintu kama karubone kandi bigahinduka mugihe cyo gucumura nyuma, bikabyara gaze imenagura igifuniko cyangwa igabanya umubano hagati ya PTFE na fibre yikirahure, bikaviramo gucika.

·  Imiterere n'ubunini bw'igitambaro cya fibre fibre : Igitambara cyijimye kandi cyinshi cyane (nk'imyenda ya satine yuzuye) cyerekana gukomera no gukumira cyane kugabanuka kwa PTFE. Hagati aho, ibinure byimbitse hagati ya fibre fibre bikunda gutera guhangayika no guturika kumpande zumwanya mugihe cyumye.
