Uburyo PTFE Ipitingi ya Tape igira ingaruka kuri bariyeri y'amazi

Igihe Ikariso ya PTFE ikoreshwa mu gufunga ibice byangiza ubushyuhe - nk'uruzitiro rwa elegitoronike, flanges ya HVAC, cyangwa ibipfundikizo bya shimi - abantu benshi bakeka ko hydrophobicity ya PTFE itanga inzitizi nziza y’amazi. Ntabwo buri gihe ari ukuri.

Molekile ziva mumazi ni nto. Zishobora gukwirakwira mu nzira ya microscopique amazi menshi adashobora. Igipimo nyacyo cyo kohereza amazi (WVTR) ya kaseti ya PTFE biterwa cyane na chimie ya PTFE nibindi biterwa nuburyo bwo gutwikira - inenge nka micropores, microcrack, hamwe na fibre ituzuye.

Aokai PTFE yasesenguye WVTR muburyo bwo gutwikira. Iyi ngingo isobanura uburyo imiterere yimiti ya PTFE, inenge zifatika, ingamba zubugari, hamwe no kuzuza byuzuza kugirango hamenyekane imikorere ya barrière.

Imiterere yimiti ya PTFE - Byombi nibyiza kandi bigarukira

1. Ibyiza - Hydrophobicity na Crystallinity

2. Imipaka - Imbaraga za Amorphous nimbaraga zintege nke

• Intege nke za intermolecular hagati ya PTFE iminyururu

• Ubusa -bwuzuye bwubusa muri amorphous domaine butera inzira yo gukwirakwiza

• Filime nziza ya PTFE itanga gusa urwego rwohejuru rwa WVTR - ruri munsi ya PVDC cyangwa EVOH

• PTFE ntabwo aribintu bisanzwe byaburiyeri

Ubushishozi bwibanze: PTFE yimbere ni inzitizi iringaniye, ntabwo ari imwe idasanzwe. Imikorere ya kaseti ifatika biterwa cyane nubusembwa.

Inenge Zitwikiriye - Micropores, Microcrack, na Fibre Wicking

Nicyo kintu cyiganje kigenga imikorere ifatika. Ibyuma bifata ibyuma byinshi bya PTFE bikozwe muburyo bwo gutera akabariro cyangwa gutwikira kwa PTFE bikurikirwa no gucumura, mugihe inenge zavutse byoroshye:

Umwanzuro ufatika: Muri rusange WVTR ya kaseti ya PTFE yarangiye ahanini igengwa nubucucike bwinenge , ntabwo umutungo wimbere wibintu byinshi bya PTFE.

Aokai PTFE itanga kaseti ya PTFE hamwe nubucucike bwateganijwe. Kuri porogaramu zisaba WVTR nkeya (<15 g / m² · umunsi), turasaba icyiciro cyacu cyinshi cyatwikiriwe, gikoresha impapuro eshatu zo gutwita kugirango gikurikirane pinholes kandi kigabanye ubukana bwa microcrack.

Gufata Ubunini hamwe na Labyrint Ingaruka - Ingamba zo Kugabanya WVTR

Kwiyongera kwububiko bwiyongera kwagura inzira zinjira mumyuka ariko bitwikiriye gusa inenge zubatswe zonyine. Ibisubizo byiza byogutezimbere urutonde hano:

Icyitonderwa hamwe nuwuzuza: Kwuzuza birenze urugero bizabangamira ibintu byoroshye kandi bidafite inkomoko yibicuruzwa byarangiye. Harasabwa gushyira mu gaciro.

Imiterere yubuso - Hydrophobique ariko ntabwo ifata icyemezo

Igikoresho cya hydrophobique PTFE gifite impande nyinshi zoguhuza amazi (mubisanzwe 110-120 °), bikabuza gukora firime yamazi ikomeza hejuru kandi bikagabanya kuburyo butaziguye imbaraga zo gutwara imyuka.

Nyamara: Iyi nyungu yo hejuru ntishobora gukuraho inzitizi mbi iterwa nubusembwa bwimbere. Niba micropore cyangwa ibice bihari, imyuka y'amazi iracyakwirakwira hatitawe kuri hydrophobicite.

Inshamake - Imikorere ya bariyeri Biterwa no kugenzura neza

Gufata ibyemezo bya nyuma: Iyo kaseti ya PTFE ifashwe kugirango ushireho ubuhehere bwinshi, inenge ziterwa na progaramu (micropores, crack, fibre fibre) bikomeza kuba intege nke zubushobozi bwa barrière. Ikidodo cyizewe kigerwaho hifashishijwe uburyo bwo kuvura ibintu byinshi birimo gutwikira ibice byinshi no guhindura ibyuzuye . PTFE ikomatanya ikora nkinzitizi yimikorere myinshi mubihe bigoye bisaba kurwanya ubushyuhe bwinshi, kurwanya ruswa, guhagarara neza, hamwe no kurekura inkoni icyarimwe - ariko ntabwo ari inzitizi yihariye ya ultra-ndende nka fayili yicyuma cyangwa PVDC.

Muri make , imitungo ya barrière yamazi ya kaseti ya PTFE ntabwo igenwa na hydrophobicity ya PTFE yonyine. PTFE yimbere ni inzitizi itagereranywa (WVTR 5-10 g / m² · umunsi wa firime idafite inenge). Nyamara, kaseti zifatika zibabazwa na micropores, microcrack (biturutse ku kwagura ubushyuhe budahuye na fiberglass), hamwe no gukuramo fibre - kuzamura WVTR kugeza kuri 50-200 g / m² · umunsi.

Kugirango ugere kuri WVTR nkeya (<15 g / m² · umunsi), vuga ibice byinshi (3+ impregnation passes) na / cyangwa lamellar wuzuza (10-20 wt% mika cyangwa ibirahuri). Ingaruka ya labyrint ituruka kubuzuza ihatira imyuka y'amazi gufata inzira zihindagurika, bikagabanya cyane kwanduza. Nyamara, kwuzuza kwinshi kurashobora kugabanya guhinduka no kudakora neza - kuringaniza birakenewe.

Ukeneye kaseti nkeya ya WVTR PTFE kugirango ifate neza? Aokai PTFE itanga ibyiciro byinshi bisize kandi byuzuza amanota hamwe namakuru yikizamini cya WVTR. Twandikire hamwe na WVTR yawe isabwa, ubushyuhe bwimikorere, nibikenewe guhinduka.

Niba ukeneye ibisobanuro birambuye bya tekiniki, ubuyobozi bwogukoresha, hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye birimo imyenda yubushyuhe bwo hejuru bwa PTFE, kaseti ya PTFE yubushyuhe bwo hejuru, umukandara wa PTFE mesh, umukandara wa fuser udafite kashe, umwenda umwe wa PTFE, umukandara wa convoyeur utagira ubushyuhe bwinshi hamwe nigitambaro cya fiberglass , nyamuneka twandikire:
