Nigute Igipimo cya Solvent Volatilisation kigira ingaruka kuri PTFE Ipapura nziza

Mu musaruro wa PTFE yubushyuhe bwo hejuru , kasike ya silicone yunvikana ikoreshwa nkigisubizo gishingiye kumuti. Mugihe kaseti yatwikiriye inyuze mu ziko ryumye, umusemburo uhumeka, ugasigara inyuma yumutwe ukomeye. Igipimo ibi bibaho - igipimo cya volatilisation ya solvent - nigikorwa cyibanze cyerekana niba ubuso bwa nyuma bufatika bworoshye, butagira inenge, kandi buhorana umubyimba, cyangwa butwikiriwe na pinholes, crater, na imirongo.

Aokai PTFE yahinduye uburyo bwo gutwikira ibicuruzwa ibihumbi. Aka gatabo gasobanura uburyo igipimo cy’ibihindagurika kigira ingaruka ku kuringaniza, ku miterere ya pinhole, no ku nenge za crater - nuburyo bwo kugenzura kaseti nziza ya PTFE.

Uburyo Igipimo cya Volatilisation kigira ingaruka kurwego - Ubucuruzi bwa Viscosity-Off

Kuringaniza nubushobozi bwa firime yometseho kugirango ikureho imirongo yatwikiriye, imirongo ihindagurika, hamwe nicunga rya orange-peel, ikora ubuso bunoze. Imbaraga zo gutwara ni impagarara hejuru; kurwanywa ni viscosity.

1. Byihuta cyane - uruhu rwo hejuru ruhagarika kuringaniza

Iyo ibishishwa bishira vuba, kwibanda kumashanyarazi hejuru bigabanuka vuba. Silicone PSA (umuti-mwinshi-uburemere bwa polysiloxane igisubizo) irumva cyane kwibanda cyane. Ubuso bwubuso bwubuso burazamuka cyane - ndetse bugakora-hejuru cyane 'uruhu ' hafi ako kanya.

Uru ruhu rufunga ibifatika bitavanze neza. Ibifatika ntibishobora kongera gutemba kugirango bigere kumurongo cyangwa ibimenyetso. Imiterere idasanzwe yakozwe mugihe cyo gutwikira ikosorwa burundu.

2. Gutinda cyane - kugabanuka no gutonyanga

Niba umusemburo uhindagurika gahoro gahoro, igiti gifatika gikomeza kuba amazi mabi cyane. Mugihe ibi bitanga umwanya wo kuringaniza, uburemere butera:

• Guswera (gufatira hejuru kumanuka hejuru yuburebure)

• Impande ndende (ibidengeri bifata ku nkombe z'ahantu hashyizweho)

• Kuvomera - ku buso-buke-bwimbaraga za PTFE (uburemere bwikigereranyo cya metero 18-20 mN / m gusa), kuvomera igihe kirekire birashobora rwose gutuma igiti kigabanuka kandi kigakura kure yubutaka, bikangiza neza neza.

Uburyo Igipimo cya Volatilisation gitera Pinholes

Ibinogo ni utwobo duto tunyuze murwego. Zikora iyo ibishishwa cyangwa umwuka mubi byafashwe bigaturika hejuru yubutaka mbere yuko ibifatika bishobora kugaruka.

1. Mechanism 1 - ibishishwa bitetse byafashwe munsi yuruhu

Iyo kaseti isize yinjiye mu ziko ryumye, izamuka ry'ubushyuhe bukabije rifatanije na ultra-yihuta ya solvent ihindagurika ikiza hejuru ya firime. Solvent yafatiwe imbere murwego rwuka cyane, ikora ibibyimba. Iyo umuvuduko wimbere umaze kumena uruhu rukomeye, firime yamenetse ntishobora kumurika no gukira - hasigara pinholes zihoraho cyangwa ikirunga kimeze nkibirunga.

2. Mechanism 2 - ibituba ntibishobora guhunga

Utubuto duto two mu kirere duhora dushinzwe mugihe cyo gutwikira no kugaburira. Birasaba umwanya uhagije wo kureremba, guturika, no gukira mubwiza buke. Niba uruhu rusa vuba vuba kubera gukama vuba, ibituba ntibishobora guhunga kandi bigashyirwaho nka pinholes.

3. Mechanism 3 - kuvomera nabi mikoro

Guhindagurika hakiri kare byihuta cyane bifata neza, bikabura igisubizo cyubushobozi bwo kuzuza buhoro buhoro imyobo mito no kwirukana umwuka wimiterere. Ibi bivamo inenge ya pinhole isa nudusembwa nyuma yo gukama.

Uburyo igipimo cya Volatilisation gitera Craters (Dimples)

Craters ni ntoya, izengurutswe hejuru yubuso, butandukanye na pinholes. Ziterwa nuburinganire bwimiterere yubusumbane.

1. Mechanism 1 - ibitonyanga byamazi

Umuvuduko ukabije wihuta ukurura ubushyuhe bwinshi bwo guhumeka, gukonjesha cyane firime itose hamwe nubutaka bwubutaka. Niba ubushyuhe bugabanutse munsi yikime cy’ibidukikije, imyuka y’amazi mu kirere iba mikoro mito kuri firime itose.

• Ubushyuhe bwo hejuru bwamazi: ~ 72 mN / m

• Ubuso bwubuso bwa silicone ifata: 20-25 mN / m

Iri tandukanyirizo rinini ritera urwego rwo hejuru rwimiterere igenda itwara ibizunguruka kugirango bigabanuke kure yigitonyanga, hasigara ibinure nyuma yo gukama.

2. Mechanism 2 - crater iterwa n'umwanda

Ubutaka-buke-bwanduye (silicone micro-ibitonyanga, amavuta) byanze bikunze bibaho mubifata cyangwa aho bikora. Iyi myanda ikora centre-yubuso-buke kuri firime itose. Ingaruka ya Marangoni, ibimera biva hanze biva muri ibyo bigo, bigatera kwiheba.

• Guhindagurika mu rugero rwemerera kwiheba kwikiza binyuze mumugongo usubira inyuma.

• Guhindagurika cyane byihuse bibuza amazi gutembera mbere yo gukira - ibinogo bifunze burundu.

3. Mechanism 3 - gutobora ibishishwa biturutse kumazi adahagije

PTFE insimburangingo ifite uburemere buke bwa 18-20 mN / m - iburyo bwurugero rushoboka. Ibikoresho bya silicone bikenera idirishya rihagije ryo gukwirakwiza no gukwirakwiza ubushuhe bwa termodinamike. Niba umusemburo uhindagurika vuba, ibifatika bitakaza amazi mbere yo gutose. Mugihe cyo kumisha, kugabanuka kwijwi hamwe no guhagarika ubuso bihatira gufatana kumasezerano, hasigara micro-crater ahantu hatose neza - bigaragara nkubuso bwerekanwe.

Ibisubizo - Nigute ushobora kugenzura ihindagurika ryubusa

Ingamba nziza yo gukemura ibibazo ikoresha impagarike :

1. Uburyo bubiri bwo kumisha

2. Sisitemu ivanze ya sisitemu

Koresha uruvange rwumuti ufite ingingo zitandukanye:

• Guteka cyane, gahoro gahoro gahoro gahoro (toluene, xylene, cyangwa aromatics / esters-itetse cyane) - igice cyingenzi - itanga igisubizo hamwe nigihe gihagije cyo kuringaniza.

• Umubare muto wo hagati / muto-utetse-byumye-byumye - byahujwe kugirango uhindure umuvuduko wumye.

3. Kugenzura ubushyuhe buhoro buhoro mu ziko ryumye

• Ubushyuhe buke kuri inlet - buhoro buhoro guhindagurika kwa kuringaniza.

• Ubushyuhe bwo hagati muri zone yo hagati - kugenzura byumye.

• Ubushyuhe bwo hejuru mugusohoka - gushiraho byihuse.

Irinde gushyushya cyane mu gice cyinjira - ibi bitera uruhu ako kanya.

4. Ingamba zinyongera

• Igenzura ubuhehere bwibidukikije - irinde guhuza amazi kuri firime itose.

• Kumurongo wa corona kuvura substrate ya PTFE - izamura ingufu zubutaka, itezimbere amazi, igabanya ibishanga.

Incamake - Ingingo zingenzi zo kugenzura ubuziranenge

Aokai PTFE itezimbere ibipimo byo gutwikira - kuvanga ibishishwa, umwirondoro wumye, hamwe no kwiyitirira substrate - kubyara kaseti ya PTFE ifite ibice byoroshye, bidafite inenge. Twandikire kugirango dushyigikire inzira cyangwa ibicuruzwa byihariye.

Ibiri hejuru byavuzwe na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba wifuza kumenya byinshi kubyerekeranye nibisobanuro birambuye, ibintu byakoreshejwe hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, imikandara ya mashini ya PTFE, imikandara yo guhuza imashini, umwenda umwe wa PTFE, imikandara ya convoyeur yihanganira ubushyuhe bwinshi hamwe nigitambara cyo hejuru cya fiberglass, twandikire:
