Hi kwihi ku hambana eka vuyelo bya ku hisa ka miseve ya infrared ku hambana na ku hisa ka ku rhendzeleka ka moya wo hisa eka ku fana ka xivumbeko lexi hlanganisiweke xa leyara ya silicone adhesive?

I. Ku Hambana ka Masungulo eka Maendlelo yo Hundzisela ku Hisisa na Tinsimu ta Mahiselo

1. Ku hisa ka ku rhendzeleka ka moya wo hisa: Convection–Conduction, Gentle na Progressive

Hilaha swi xiyiweke hakona hi Muendli wa thepi ya mahiselo yale henhla ya PTFE , kuhisa ku hundziseriwa hiku tirhisa convection ya moya wo hisa kuya ehenhla ka leyara yo namarhela, kutani ku fambisiwa endzeni kusuka ehenhla hiku tirhisa thermal conduction. Ti silicone adhesives tina thermal conductivity yale hansi swinene (kwalomu ka 0.2 W/m·K), hikokwalaho ka sweswo ku cinca cinca ka mahiselo exikarhi kale handle nale ndzeni aswi papalateki. Hambiswiritano, gradient leyi yi ringanerile swinene, yi yimela ndlela yo hisa leyi ringaniseriweke emisaveni hinkwayo leyi nga ni mpimo wo hisa lowu nonokaka.

2. Ku Hisisa ka Radiation ya Infrared: Radiation–Absorption, Ku Hlanganisiwa ka le Henhla

Eneji ya infrared yi amukeriwa hi swihlanganisi swa tikhemikhali eka xinamarheti xa silicone (kufana na Si–O). Hi xitalo, matimba lawa ya amukeriwa swinene hi leyara yale henhla leyinga e hansi swinene (hiku landzelelana ka ti micrometers kuya eka ti millimeters) naswona ya hundzuriwa kuva kuhisa, leswi endzhaku swifambisiwaka endzeni, leswi endlaka leswaku kuva na xiyimo xale henhla xa 'surface-to-interior' temperature gradient. Ntsena loko wavelength yi fambelana hiku hetiseka na nhlohlorhi ya absorption ya substrate laha kunga fikeleriwa ku hisiwa ka le ndzeni nale handle ka nkarhi wun'we 'volumetric'.

3. Ku pimanisiwa ka Swihlawulekisi swa Nsimu ya Mahiselo

Ku rhendzeleka ka moya wo hisa swi humesa ndzhawu ya mahiselo leyi fanaka hi ndzhawu leyi cincaka hiku nonoka hiku famba ka nkarhi. Hi hala tlhelo, miseve ya infrared yi simeka hi ku olova nsimu ya nkarhinyana leyi nga faniki swinene ya mahiselo ya le henhla eka tlhelo ra vukulu.

II. Ku fana ka ku hangalasiwa ka ndhawu ya Crosslink Density

1. Ku rhendzeleka ka moya wo hisa: Gradient yo ringanela, Xiphemu xo tsemakanya lexi fanaka

Ku tlakuka ka mahiselo hiku nonoka swipfumelela swiphemu swale ndzeni nale handle swa adhesive layer kuva swinghena eka vulcanization temperature range kwalomu ka nkarhi wun’we. Nhlamulo ya crosslinking yiya emahlweni hiku fambisana eka xibakabaka, leswi endlaka leswaku kuva na ku hangalasiwa ka crosslink density leyi fanaka kuya hi tlhelo ra vukulu, na xivumbeko xa network hinkwayo lexi nga cincekiki naswona kungari na tindzhawu ta nkoka ta over-crosslinking kumbe under-crosslinking.

2. Infrared Radiation: Surface Cured, Endzeni Under-Cured, Steep Gradient

Ku tswongiwa lokukulu ka le henhla swiendla leswaku leyara yale henhla yifika eka mahiselo yale henhla hiku hatlisa naswona yihetiseka ku crosslinking hiku hatlisa, leswi endlaka nhlonge yo enta leyi horisiweke. Leyara leyi horisiweke yitirha tani hi xisirhelelo xa mahiselo, yi sivela ku hundziseriwa ka kuhisa kuya endzeni naswona yi siya xiphemu xale ndzeni eka mahiselo yale hansi kuringana nkarhi woleha. Mbuyelo wohetelela i xivumbeko xa gradient laha crosslink density yihungutekaka swinene kusuka e henhla kuya endzeni, leswi kombisaka kufana lokunga kahle swinene.

3. Vuyelo Bya Nhlonge Lowu Horisiweke

Ku horisiwa ka le henhla ka le henhla ka ha ri emahlweni a swi siveli ntsena ku fambisiwa ka ku hisa kambe swi tlhela swi pfalela eka volume, leswi sivelaka ku hunguteka loku landzelaka hinkarhi wa ku horisiwa ka le ndzeni. Leswi swi nyanyisa ku nga fani ka xivumbeko naswona swi nghenisa ntshikilelo wa le ndzeni.

III. Vutshembeki bya Netiweke ya Microscopic na Vulawuri bya Swihoxo

1. Ku rhendzeleka ka Moya wo Hisa: Nhluvukiso wa Netiweke ya Synchronous, Swihoxo Switsongo

Ku hisa hinkwako hiku nonoka nakufana swipfumelela crosslinking reaction kuva yiya emahlweni hiku fambisana naku ya emahlweni eka leyara hinkwayo ya adhesive. Ti molecular chains tina nkarhi lowu ringaneleke wa conformational relaxation, leswi olovisaka ku tumbuluxiwa ka network leyinene leyingana ti crosslinking points leti hangalasiweke hindlela yofana, ti network chains leti hlelekeke kahle, na swihoxo swintsongo, xikan’we na ntshikelelo wale hansi wa le ndzeni.

2. Infrared Radiation: Yi tala ku hambanisiwa ka swiphemu na ku hlangana ka ntshikelelo

Steep temperature gradient xikan’we na differential curing rates swinga hlohletela ntshikelelo lowukulu wa mahiselo xikan’we na ntshikelelo wa curing shrinkage. Ku gelation hi xihatla ka leyara ya le henhla 'freezes' volume; loko endzeni ka yona ku hola endzhaku, ku hunguteka ka yona ku siveriwa hi leyara yale henhla, leswi yisaka eka nhlayo yale henhla ya ntshikelelo eka interface hambi kuri kusunguriwa ka ti microcracks. Hi nkarhi wolowo, ku tirhisiwa loku nga ringaniki ka mintlawa leyi hlamulaka swi tumbuluxa 'ti-hard regions' leti fuweke hi crosslink na 'soft regions' leti nga riki na crosslink, leswi vangaka ku hambanisiwa ka swiphemu swa microscopic na ku kavanyeta ku fana ka netiweke.

3. Ku kavanyetiwa kusuka eka Byproduct kumbe Solvent Outgassing

Ku tlakuka ka mahiselo hiku olova ka ku rhendzeleka ka moya wo hisa swipfumelela switirhisiwa leswintsongo swa ti molecules (kufana na ti alcohols kumbe mati lawa ya humesiwaka hi condensation-cure silicones) kuva swi hangalaka naku khuluka hiku ntshunxeka, leswi papalataka ku endliwa ka bubble. Infrared curing, hambiswiritano, yitala ngopfu ku pfalela ti outgassing channels hikokwalaho ka premature surface curing, leswi humesaka ti bubbles kumbe porous voids leswinga kavanyeta hiku kongoma macroscopic density ya crosslinked network.

IV. Mahetelelo: Nkoka wa ku hambana ka ku fana na ku hlawula ka matirhiselo

Maendlelo mambirhi yo horisa yana switandzhaku leswi hambaneke hi diametrically eka crosslinked structure uniformity. Ku rhendzeleka ka moya wo hisa ku xaviselana vukorhokeri eka nsimu leyi fambiwaka hi ku hisa, leyi lawuriwaka, na mahiselo yo ringanela, ku tiyisisa ku ringanana ka crosslink density ku tsemakanya tlhelo ra vukulu na network ya microscopic leyi heleleke. I nhlawulo lowu nga papalatekiki eka switirhisiwa leswi lavaka ku tshembheka ka le henhla na ku fana ka xivumbeko, kufana na potting na thick-layer coatings. Infrared radiation, hiku hambana, hikokwalaho ka ku humesiwa loku hlanganisiweke ka eneji ehenhla, hi ntumbuluko yitala ku tumbuluxa mahiselo lawa yanga faniki na tinsimu to horisa, hiku olova ku humesa swivumbeko swa gradient crosslinked xikan’we na swihoxo swohambana hambana. Fasitere ra yona ro lulamisa ri komile swinene, leswi endlaka leswaku yifaneleka ngopfu eka ku horisa hiku hatlisa ka swifunengeto swo olova (micron-scale) laha swilaveko swa uniformity swinga ehansi. Ku hlawula exikarhi ka leswimbirhi hi xiviri i ku cinca-cinca exikarhi ka 'ku tirha kahle' na 'ku fana.'

Rungula leri nga laha henhla ri nyikiwile hi Jiangsu Aokai New Material Technology Co., Ltd. , muendli wa thepi ya mahiselo ya le henhla ya PTFE.

Loko u lava ku dyondza swo tala hi swihlawulekisi swa vuxokoxoko, swiyimo swa xikombelo, na swihlawulekisi swa ku endla hi ku landza swilaveko swa nxaxamelo wa hina hinkwawo wa swikumiwa – ku katsa na lapi ra mahiselo ya le henhla ya PTFE, thepi ya mahiselo ya le henhla ya PTFE, mabandhi ya mesh ya mahiselo ya le henhla ya Teflon, mabandhi ya muchini wo boha lama nga na swirhabyani, lapi ra PTFE ra tlhelo rin’we, mabandhi ya conveyor ya mahiselo ya le henhla, na ku tiyisela ku hisa malapi ya fiberglass – hi kombela u ntshunxeka ku hi tihlanganisa hi ku tirhisa leswi landzelaka:
