I. Misiyano Yakakosha muMaitirwo Ekufambisa Kupisa uye Nzvimbo dzeTembiricha
1. Hot-Air Circulation Heating: Convection-Conduction, Nyoro uye Inofambira mberi
Sezvakataurwa na PTFE yakakwirira-tembiricha tepi inogadzira, kupisa kunotamiswa kuburikidza nemhepo inopisa convection kusvika pamusoro peiyo adhesive layer, uye yozoitwa mukati kubva pamusoro kuburikidza nekupisa conduction. Silicone adhesives ane yakanyanya kuderera kupisa conductivity (inenge 0.2 W/m·K), saka tembiricha gradient pakati pekunze uye mukati hazvidzivisike. Nekudaro, iyi gradient ine mwero, inomiririra yepasi rose yakadzikama kudziyisa modhi ine inononoka kudziya mwero.
2. Infrared Radiation Heating: Radiation-Absorption, Surface-Yakatarisana
Infrared simba rinotorwa nemakemikari zvisungo mune silicone adhesive (yakadai seSi-O). Kakawanda, simba racho rinotorwa zvakanyanya neiyo isina kudzika yepasi layer (pakurongeka kwema micrometer kusvika kumamilimita) uye inoshandurwa kuita kupisa, iyo inozoitwa mukati, ichigadzira kukwirisa 'pamusoro-kusvika-mukati' tembiricha gradient. Chete kana wavelength ichinyatsoenderana nepamusoro pekunyura kweiyo substrate inogona 'volumetric' kupisa panguva imwe chete yemukati nekunze kuwanikwa.
3. Kuenzanisa kweTemperature Field Characteristics
Kutenderera kwemhepo kunopisa kunoburitsa nzvimbo yetembiricha yakaenzana inoshanduka zvishoma nezvishoma nekufamba kwenguva. Infrared radiation, kune rumwe rutivi, inomisikidza yakanyanyisa isina yunifomu inopfupika-yepamusoro-tembiricha munda munzira yekukora.
Iyo inononoka tembiricha kukwira inobvumira iyo yemukati uye yekunze zvikamu zveadhesive layer kuti ipinde vulcanization tembiricha renji kanenge panguva imwe chete. Iyo crosslinking reaction inoenderera ichienderana muchadenga, zvichikonzera yunifomu yecrosslink density kugovera pamwe negwara reukobvu, ine inowirirana yakazara network chimiro uye pasina matunhu akakosha e-over-crosslinking kana under-crosslinking.
2. Infrared Radiation: Surface Yakaporeswa, Interior Under-Cured, Steep Gradient
Kunyura kwepamusoro pepamusoro kunokonzera kuti musara wepamusoro usvike pakupisa kwepamusoro ipapo uye upedze kuyambuka nekukasira, uchigadzira ganda rakapora. Iri rakaporeswa layer rinoita sechivharo chekupisa, chinotadzisa kupisa kuenda mukati uye kusiya chikamu chemukati pane yakaderera tembiricha kwenguva yakareba. Mhedzisiro yekupedzisira ndeye gradient chimiro apo crosslink density inodzikira zvakanyanya kubva kumusoro ichienda mukati, ichiratidza kusafanana kwakashata.
3. The Curred-Skin Effect
Kurapa kusati kwasvika kwepamusoro pedenga hakungovharidzi conduction yekupisa asiwo kukiya muvhoriyamu, kurambidza kuderera kunotevera panguva yekurapa kwemukati. Izvi zvinowedzera kuwedzera kwemaitiro asina kufanana uye zvinounza kushushikana kwemukati.
III. Microscopic Network Kutendeseka uye Kukanganisa Kudzora
1. Hot-Air Circulation: Synchronous Network Development, Mashoma Mashoma
Iko kudziya kwese kunononoka uye kwakafanana kunobvumira iyo crosslinking reaction kuti ienderere mberi neyakafanana uye zvishoma nezvishoma mukati meiyo yese yekunamatira layer. Cheni dzemamorekuru dzine nguva yakakwana yekuzorora, kufambisa kuumbwa kwetiweki yakanakira ine yakagovaniswa yakaganhurwa mapoinzi, yakanyatso kurongeka network cheni, uye hurema hushoma, pamwe nekushomeka kwemukati.
2. Infrared Radiation: Inotarisana nePase Separation uye Stress Concentration
Iyo yakadzika tembiricha gradient uye mutsauko wekurapa mitengo inogona kukonzeresa kushushikana kwekushisa uye kurapa shrinkage kushushikana. Iko kukurumidza kugezesa kwepamusoro pedenga 'inoomesa' vhoriyamu; apo iyo yemukati inorapa gare gare, shrinkage yayo inomanikidzwa nepamusoro pedenga, zvichitungamira kune yakanyanya kushushikana kushushikana pane iyo interface uye kunyangwe kutangwa kwe microcracks. Zvichakadaro, kushandiswa zvisina kuenzana kwemapoka anochinja-chinja kunogadzira 'nzvimbo dzakaoma' dzakachinjika uye 'nzvimbo dzakapfava' dzakachinjika, zvichikonzera kupatsanurwa kwechikamu uye kukanganisa network kufanana.
3. Kupindira kubva kuByproduct kana Solvent Outgassing
Tembiricha yakapfava yekukwira kwemhepo inopisa-inotenderera inobvumira madiki-morekuru byproducts (senge madoro kana mvura inoburitswa necondensation-kurapa silicones) kupararira uye kubuda pachena, kudzivirira kuumbwa kwebubble. Kurapa infrared, zvisinei, kunoda zvakanyanya kuvhara machani ekubuda kunze nekuda kwekukurumidza kupora kwepamusoro, kugadzira mabhuru kana porous voids inokanganisa zvakananga macroscopic density yeiyo crosslinked network.
Idzi nzira mbiri dzekurapa dzine diametrically inopesana nemhedzisiro pane yakachinjika chimiro kufanana. Kupisa-mhepo kutenderera kunotengesa kushanda zvakanaka kweiyo thermally conduction-inotyairwa, inodzoreka, uye ine mwero tembiricha munda, kuve nechokwadi cheuniform crosslink density mhiri ukobvu nzira uye yakazara microscopic network. Ndiyo sarudzo isingadzivisike yezvikumbiro zvinoda kuvimbika kwakanyanya uye kuenzana kwechimiro, senge potting uye makobvu-layer coatings. Infrared radiation, nemusiyano, nekuda kwekunyudzwa kwesimba pamusoro pepamusoro, inogara ichigadzira isina-uniform tembiricha uye minda yekurapa, ichigadzira zviri nyore gradient crosslinked zvimiro uye kuremara kwakasiyana. Hwindo rayo rekugadzirisa rakatetepa zvakanyanya, zvichiita kuti rive rakakodzera kukurumidza kurapwa kweakaonda machira (micron-scale) uko kufanana kunodiwa kwakaderera. Sarudzo pakati pezviviri inyaya yekutengeserana pakati pe 'kubudirira' uye 'kufanana.'
Mashoko ari pamusoro apa anopiwa ne Jiangsu Aokai New Material Technology Co., Ltd. , inogadzira tepi yemhando yepamusoro yePTFE.
Kana iwe uchida kudzidza zvakawanda pamusoro pezvakatsanangurwa zvakatsanangurwa, mamiriro ekushandiswa, uye sarudzo dzekugadzirisa kune zvizere zvechigadzirwa chedu - kusanganisira PTFE high-temperature jira, PTFE high-temperature tepi, Teflon high-temperature mesh mabhandi, seamless bonding machine bhandi, single-sided PTFE jira, high-temperature inodzivirira, faibha inodzivirira kupisa, uye fiber girasi inonzwa. kuburikidza nezvinotevera:
