I. Bambance-bambancen Mahimmanci a Tsarin Canjin Zafi da Filayen Zazzabi
1. Dumamar Zazzafar Iska mai zafi: Convection-Gudanarwa, Mai laushi da Ci gaba
Kamar yadda sanarwar ta bayyana PTFE high-zazzabi tef manufacturer, zafi yana canjawa wuri ta hanyar zafi iska convection zuwa saman da m Layer, sa'an nan gudanar da ciki daga surface ta thermal conduction. Silicone adhesives suna da ƙarancin ƙarancin zafin jiki (kimanin 0.2 W/m·K), don haka ƙarancin zafin jiki tsakanin waje da ciki ba makawa. Koyaya, wannan gradient yana da matsakaicin matsakaici, yana wakiltar daidaitaccen yanayin dumama na duniya tare da jinkirin dumama.
Ƙarfin infrared yana ɗauka ta hanyar haɗin sinadarai a cikin mannen silicone (kamar Si-O). A mafi yawan lokuta, makamashin yana tsotsewa ta wurin shimfidar wuri marar zurfi (a kan tsari na micrometers zuwa millimeters) kuma yana juyewa zuwa zafi, wanda sai a gudanar da shi a ciki, yana haifar da matsananciyar yanayin zafin 'surface-zuwa-ciki'. Sai kawai lokacin da tsayin tsayin ya yi daidai da kololuwar juzu'i na substrate za a iya samun dumama ciki da waje a lokaci guda.

Zazzagewar iska mai zafi yana samar da filin yanayin zafi iri ɗaya wanda ke tasowa a hankali akan lokaci. Infrared radiation, a daya bangaren, a shirye ya kafa wani musamman mara-uniform mai wucewa filin zafi mai zafi a cikin kauri shugabanci.
II. Daidaita Rarraba Rarraba sararin samaniya na Crosslink Density
1. Zazzafar iska mai zafi: Matsakaici Gradient, Uniform Cross-Section
Jinkirin haɓakar zafin jiki yana ba da damar ciki da waje na ɓangaren mannewa don shigar da kewayon zazzabi kusan lokaci guda. Halin haɗin kai yana gudana tare a cikin sararin samaniya, yana haifar da rarraba haɗin haɗin haɗin kai tare da kauri mai kauri, tare da daidaitaccen tsarin cibiyar sadarwa gabaɗaya kuma babu wani yanki mai mahimmanci na tsallake-tsallake ko ƙetare.
Tsananin shayar da ƙasa yana haifar da saman saman ya kai ga zafin jiki mai zafi nan take kuma ya cika haɗin kai cikin sauri, yana samar da fata mai laushi. Wannan Layer ɗin da aka warke yana aiki azaman shinge na thermal, yana hana canja wurin zafi zuwa ciki da barin ɓangaren ciki a ƙananan zafin jiki na tsawon lokaci. Sakamako na ƙarshe shine tsarin gradient inda yawan haɗin haɗin ke raguwa sosai daga saman ciki, yana nuna rashin daidaituwa sosai.

Maganin da ba a kai ba na saman saman ba kawai yana toshe tafiyar zafi ba har ma yana kulle ƙarar, yana hana raguwa na gaba yayin warkewar ciki. Wannan yana ƙara tsananta rashin daidaituwa na tsari kuma yana gabatar da damuwa na ciki.
1. Zazzafar iska mai zafi: Haɓaka hanyar sadarwa mai aiki tare, ƙarancin lahani
Gabaɗayan jinkirin da dumama iri ɗaya yana ba da damar haɗin kai don ci gaba tare da ci gaba da ci gaba a cikin duka Layer ɗin mannewa. Sarƙoƙin ƙwayoyin cuta suna da isasshen lokaci don annashuwa da daidaituwa, suna sauƙaƙe ƙirƙirar hanyar sadarwa mai kyau tare da wuraren haɗin kai da aka rarraba iri ɗaya, sarƙoƙin cibiyar sadarwa da aka yi oda, da ƙarancin lahani, tare da ƙarancin damuwa na ciki.
2. Infrared Radiation: Mai yiwuwa ga rabuwar lokaci da damuwa
Matsakaicin girman zafin jiki da ƙimar warkewa daban-daban na iya haifar da matsi na zafi mai mahimmanci da magance damuwa. Saurin gelation na saman Layer 'yana daskare' ƙarar; lokacin da ciki ya warke daga baya, raguwar sa yana ƙuntatawa ta saman Layer, yana haifar da babban damuwa a cikin dubawa har ma da farawa na microcracks.

3. Tsangwama daga Kayayyakin Samfura ko Magance Gas
Ƙaunar zafin jiki mai laushi na zazzagewar iska yana ba da damar ƙananan ƙwayoyin ƙwayoyin cuta (kamar alcohols ko ruwan da aka saki ta hanyar siliki-magani) don yaduwa da ƙafe cikin yardar kaina, guje wa samuwar kumfa. Infrared curing, duk da haka, yana da matuƙar wuya ga rufe tashoshi masu fitar da iskar gas saboda da wuri warkewa, samar da kumfa ko porous kuraje wanda kai tsaye yin sulhu da macroscopic yawa na crosslinked cibiyar sadarwa.
IV. Kammalawa: Mahimman Bambance-bambancen Uniformity da Zaɓuɓɓukan Aikace-aikace
Hanyoyi biyu na warkewa suna da tasirin sabanin ra'ayi akan daidaiton tsarin da ke da alaƙa. Zazzagewar iska mai zafi yana cinikin ingantacciyar hanyar sarrafawa ta thermally, mai sarrafawa, da matsakaicin filin zafin jiki, yana tabbatar da haɗin haɗin haɗin kai guda ɗaya a kan hanyar kauri da cikakkiyar hanyar sadarwa. Zaɓin da ba makawa ne don aikace-aikacen da ke buƙatar babban aminci da daidaiton tsari, irin su tukwane da sutura masu kauri. Infrared radiation, da bambanci, saboda mayar da hankali saki makamashi a saman, na halitta oyan haifar da marasa Uniform zafin jiki da kuma warkewa filayen, shiryayye samar da gradient crosslinked Tsarin da daban-daban lahani. Tagar sarrafa ta tana da kunkuntar sosai, yana mai da shi dacewa da farko don saurin warkewar siraran sutura (micron-sikelin) inda buƙatun daidaito ba su da yawa. Zaɓin da ke tsakanin su biyun shine ainihin ciniki tsakanin 'inganci' da 'uniformity.'
Idan kuna son ƙarin koyo game da cikakkun bayanai dalla-dalla, yanayin aikace-aikacen, da zaɓuɓɓukan gyare-gyare don kewayon samfuranmu - gami da masana'anta mai zafin jiki na PTFE, tef ɗin zafin jiki mai zafi, Teflon babban ɗamarar ɗamara, bel ɗin na'ura mai haɗawa mara ƙarfi, masana'anta PTFE mai gefe guda, babban zafin jiki mai ɗaukar hoto - bel ɗin zafi mai ɗorewa ta hanyar bel ɗin zafi mai zafi, don Allah mai zuwa:
