Ndlela Yo Susa Swiengeteri leswi Saleke na Swilo swa Molekhuli ya le Hansi eka Xifunengeto Hi Nkarhi wa Vuhumelerisi bya Lapi ra PTFE ra Mahiselo ya le Henhla

Jiangsu Aokai Switirhisiwa Leswintshwa – PTFE Muendli wa Lapi ra Mahiselo ya le Henhla, u ku komba ndlela. Hi nkarhi wa vuhumelerisi bya lapi ra xiyimo xale henhla ra PTFE ra mahiselo yale henhla, swiengeteri leswi saleke na swilo swa molecule yale hansi eka xifunengeto i swilo swa nkoka leswi khumbhaka ku tiya ko hetelela ka kuhisa, nhundzu yo humesa xikan’we na vuhlayiseki bya swakudya swa xiendliwa. Ku tiyisisa leswaku matirhelo ya lapi ra mahiselo yale henhla ya PTFE ya fikelela swipimelo, endlelo ro tika ra switeji swotala i ra nkoka ku susa thyaka leri.

Xiyenge xa ​​Nkoka: Ku basisiwa ka Vutshunguri bya ku Hisa bya Nkoka eka PTFE High-Temperature Cloth Coating

Leri i endlelo ra nkoka swinene eka vuhumelerisi bya malapi ya mahiselo yale henhla ya PTFE, lawa ya fikelelaka ku hambanisiwa ka nyama ka thyaka ra coating hiku tirhisa vulawuri bya mahiselo lebyi kongomeke.

Endzhaku ka PTFE emulsion impregnation ya PTFE high-temperature cloth substrate, xiendliwa xisungula ku nghena eka oven yo omisa ya mahiselo yale hansi. Eka filimi leyi tsakamaka ehenhla, hi ntolovelo mahiselo ya lawuriwa eka 240–285°C . Goza leri ari kongomisiwi eka ku endla film yo peta, kambe ku pfurhetela ndzhongho, ti solvents nati surfactants eka swivandla swa coating hiku tirhisa moya wo hisa. Ku tlula xiteji lexi naku endla hiku kongoma sintering ya mahiselo yale henhla swita endla leswaku kuva na ti pinholes kumbe ti bubbles ehenhla, leswi onhaka swinene ku hlangana ka lapi ra PTFE ra mahiselo yale henhla.

Endzhaku ka sweswo, lapi ra PTFE ra mahiselo yale henhla ri nghena eka ndzhawu ya mahiselo yale henhla ya 360–380°C . Eka mahiselo lawa, swiphemuphemu swa PTFE ehenhla swisungula ku n’oka naku khuluka, leswi endlaka filimi yo sirhelela leyi yaka emahlweni. Hi nkarhi walowo, mahiselo lawa yale henhla ka PTFE melting point yanyika kinetic energy leyi ringaneleke eka ti residual oligomers nati unreacted monomers endzeni ka coating kuva ti vaporize naku baleka kusuka eka substrate. Ku lawula kahle mahiselo ya sintering swina nkoka swinene eka ku basa ka lapi ra PTFE ra mahiselo yale henhla:

· Mahiselo yale hansi ka 360°C ya yisa eka ku khuluka lokunga helelangiki ka thyaka rale ndzeni;

· Mahiselo yale henhla ka 390°C yavanga ku tshoveka naku bola ka ti molecular chains ta PTFE, leswi thyakisa coating ematshan’wini ya sweswo.

Xiyenge xa ​​Vumbirhi: Vulawuri bya Maendlelo ya kahle eka Vuhumelerisi bya Malapi ya Mahiselo ya le Henhla ya PTFE

Ku engetela eka vutshunguri bya core thermal, vulawuri bya vuxokoxoko hinkarhi wa vuhumelerisi byitlhela byi pfuneta ku antswisa grade ya vuhlayiseki bya lapi ra PTFE ra mahiselo yale henhla.

· Substrate Pretreatment : Loko kungase peta, lapi ra fiberglass leri tirhisiwaka eka lapi ra PTFE ra mahiselo yale henhla ri endla vutshunguri bya dewaxing na degumming hi vukheta. Masalela ya organic eka base fabric yata carbonize hinkarhi wa ku hisiwa loku landzelaka naswona yatshama eka interlayer, ya endla swihoxo leswi phikelelaka leswinga herisiwiki.

· Ku Hlantswa loku Pfunetaka : Eka lapi ra PTFE ra mahiselo yale henhla leri lavaka ku basa lokukulu, ku basisiwa ka inthanete hi swintshuxo swokarhi kumbe vutshunguri bya ultrasonic swinga tirhisiwa eka switirhisiwa leswinga hetiwangiki ngopfu, ku ndlandlamuxa ku susiwa ka ntshuri wale henhla xikan’we naku lulamisa swivati ​​swa oyili.

Xiyenge xa ​​Vunharhu: Qhinga ra Vulawuri bya Xihlovo ra Vuhumelerisi bya Malapi ya Mahiselo ya le Henhla ya PTFE

Ndlela leyinene yo basisa i ku kavanyeta thyaka loko yanga se nghena eka sisiteme ya swihumelerisiwa, leswi lavaka leswaku vaphakeri va malapi ya mahiselo yale henhla ya PTFE va simeka swipimelo swo tika swa vulawuri bya xihlovo.

· Ku Hlawuriwa ka Switirhisiwa swa Khwalithi ya le Henhla : I ti resins ta PTFE dispersion ta vutengi bya le henhla ntsena leti nga na ku basa loku nga riki ehansi ka 99.9% leti faneleke ku tirhisiwa tanihi switirhisiwa swo peta. Ti resins ta xiyimo xale hansi tina swilo swotala swinene swa molecule yale hansi, leswi endlaka leswaku swinga koteki ku humelerisa lapi ra PTFE leri faneleke ra mahiselo yale henhla kunga khathariseki leswaku sintering yi antswisiwile njhani endzhaku.

· Vulawuri bya Auxiliary Agent : Loko switolwa kumbe switirhisiwa swo levela swi laveka eka ku endliwa ka coating, tinxaka letinga vila ehansi, leti cinca cincaka swinene tita hlawuriwa, naswona mpimo wa tona wu lawuriwa swinene ku tiyisisa ku herisiwa hiku hetiseka eka xitirhisiwa lexi hetiweke.

· Ndzhawu yo Basisa ya Vuhumelerisi : Nhlengeletano ya vuhumelerisi yita hlayisa ntshikelelo lowunene na ku basa. Endzeni ka switirhisiwa swifunengetiwe hi PTFE kutani swi endliwe hi nsimbi yoka yinga tshwukangi ku sivela ntshuri na thyaka kusuka eka mbango kumbe ku rhurhumela ka switirhisiwa kuva swinga weli eka filimi leyi tsakamaka naswona swi endla swivati ​​swa thyaka swa mihlovo eka xifunengeto.

Nkoka wa ku susa swilo leswi saleke eka swifunengeto swa malapi swa mahiselo yale henhla ya PTFE swile ka vulawuri lebyi kongomeke bya mahiselo ya sintering na curve yo hisa. Hiku hlanganisa ntsena vutshunguri bya mahiselo na vulawuri bya vuhlayiselo bya maendlelo hinkwawo laha lapi ra mahiselo yale henhla ra PTFE leri hetiweke ri nga tisaka swivumbeko swa kahle swinene leswinga namarheli, leswinga tiyisela kuhisa na ku pfaleriwa ka le henhla.

Rungula leri nga laha henhla ri nyikiwile hi Jiangsu Aokai New Materials Technology Co., Ltd.

Ku kuma vuxokoxoko bya tipharamitha, swiyimo swa xikombelo na swintshuxo leswi endleriweke wena 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, bandi ra mesh ra mahiselo ya le henhla ya PTFE, bandi leri nga riki na swirhabyani ra michini yo boha, lapi ra PTFE ra tlhelo rin’we, mabandhi yo fambisa lama lwisanaka na mahiselo ya le henhla na lapi ra fiberglass ra mahiselo ya le henhla, hi kombela u titwa u ntshunxekile ku tihlanganisa hina hi ku tirhisa:
