Hi wahi tindlela to kambela eka swivumbeko swo lwisana na ku namarhela na ku olova ku basisa swa lapi ra fiberglass leri pfanganisiweke na PTFE mayelana na swivati ​​swa oyili na ntshuri?

1. Ku Kamberiwa ka Angle ya Contact na Eneji ya le Henhla (Swisekelo swa ku tsakama) .

 

- Static Contact Angle: Yi pimiwa hiku tirhisa mati na diiodomethane (kumbe hexadecane) hiku hambana. Angle ya contact ya mati hi ntolovelo yiva ehenhla ka 110°. Angle yale henhla ya oil contact yikomba ku tiya swinene eka oil fouling xikan’we naku namarhela.

- Rolling/Sliding Angle: Angle leyi thonsi ra volume yo karhi ri sungulaka ku rhetela kusuka eka ndzhawu leyi rhetaka hiku nonoka. Rolling angle leyintsongo yikomba swivumbeko swo antswa swa anti-sticking xikan’we naku basisa hiku olova, leswinga swa nkoka swinene eka ku kamberiwa ka oil stain.

- Surface Free Energy Calculation:Swiphemu swa polar na dispersive swi hlayeriwa hiku tirhisa tindlela tofana na Owens-Wendt. Loko energy yale henhla yale hansi (PTFE’s ideal value is kwalomu ka 18–20 mN/m), switika swinene leswaku swilo leswinga tiya na swilo leswinga mati switsakama naku hangalaka.

 

2. Ku Kamberiwa ka Michini ka Swihlawulekisi swo Lwisana na ku Namarhela (Matimba ya Peel/Matimba yo Namarhela) .

 

- Standard Pressure-Sensitive Tape Peel Test: Thepi ya ntolovelo leyi boxiweke (xikombiso, 3M 810 kumbe thepi leyi hlawuriweke leyi nga na ntshikelelo) yi tshikileriwa eka vuandlalo bya thepi ya PTFE hiku tirhisa roller ya ntolovelo. Endzhaku ko tshikiwa yi yima nkarhi lowu vekiweke, ku endliwa xikambelo xa 180° xa peel hi muchini wo kambela tensile (languta eka GB/T 2792). Loko matimba ya peel yari ehansi, ndzhawu ya anti-sticking ya tiya, laha kungana nhlayo leyinene yale hansi ka 0.1 N/25 mm.

- Specific Medium Adhesion Test: Swilo swo namarhela leswi hakunene swi hlanganaka na swona loko swi tirhisiwa, ku fana na asphalt, malebvu yo tinamarhela, kumbe swinamarheti leswi hisaka, swi tirhisiwa ku pima matimba lama lavekaka ku swi hluvula ehenhla.

 

3. Swikambelo leswi tekeleriweke swa ku tiya ka oyili na ku basisiwa hi ku olova

 

- Oil Stains Sliding/Residue Method: Nhlayo leyi vekiweke ya oyili ya njhini, oyili yo sweka, kumbe mafurha yo endliwa yi cheriwa eka xikombiso lexi rhendzelekeke hi angle yo karhi. Ku leha ka sliding ya oil stain kumbe tiphesente ta ndzhawu leyi saleke ehenhla ka yona swa pimiwa.

- Vutshila byo Hlantswa Ku Sula hi Nhlayo:

    - Misava ya standard artificial (nkatsakanyo wa carbon black, grease, na oleic acid) yi cheriwa hiku ringana no omisiwa. Lapi leri nga riki na lint leri tsakamisiweke hi mati ni xibasisi lexi nga riki na xihlawuhlawu ri tirhisiwa ku sula emahlweni ni le ndzhaku ku ringana nhlayo leyi vekiweke ya swirhendzevutana ehansi ka ndzhwalo lowu vekiweke.

    - Vaendli va lapi ra fiberglass leri pfanganisiweke na PTFE e Jiangsu hi ntolovelo va tirhisa mitara ya ku hambana ka mihlovo ku pima ku hambana ka mihlovo ΔE emahlweni na le ndzhaku ka ku sula, kumbe ku pima vuswikoti byo basisa hi vukulu bya misava leyi saleke (ndlela ya gravimetric). ΔE leyintsongo na ntiko wa le hansi wa masalela swikomba matirhelo yo antswa yo basisa hiku olova. Nhlayo ya ku vuyiseriwa ka contact angle eka ndzhawu leyi basisiweke na yona yinga pimiwa.

- Xikambelo xa Khwalithi xa Xihatla hi Ximaki xa Mafurha: Ximaki xa mafurha xi tirhisiwa ku dirowa milayeni ehenhla. Languta loko inki yi hunguteka yi va mathonsi lama nga fambisaniki kumbe yi hangalaka yi ya emahlweni, ivi u sula hi lapi leri omeke ku vona loko yi susiwa hi ku olova. Kuhunguteka loku vonakaka xikan’we naku susiwa hiku olova swikomba swivumbeko swa kahle swa anti-fouling xikan’we naku basisa hiku olova.

 

4. Ku Kamberiwa ka ku Namarhela ka Anti-Dust na Anti-Particle

 

- Ndlela yo veka ntshuri: Ntshuri wa xikambelo xa ntolovelo (xikombiso, ISO 12103-1 A2 fine dust) wu pfumeleriwa ku tshamiseka hi ntumbuluko eka swiphemu swa xikombiso leswi nga vertically kumbe 45°-inclined endzeni ka kamara leri pfalekeke. Endzhaku ko ba hi vukheta kumbe ku pfurha hi gasi ya ntshikelelo wale hansi, ndzhawu ya ntshuri leyi saleke/mass yi pimiwa hiku tirhisa image analysis kumbe maendlelo ya gravimetric.

- Ku Susiwa ka ntshuri hi Ndlela ya Airflow: Nhlayo leyi tivekaka ya ntshuri yi fafazeriwa hiku ringana eka xikombiso lexi nga horizontal. Mpimo wa ku khuluka ka nayitrojini wu engeteriwa hakatsongo-tsongo, naswona rivilo ra le hansi ra ku khuluka ka moya leri lavekaka leswaku ku pfurha ntshuri hi ku helela ra rhekhodiwa. Loko rivilo yiri ehansi, ndzhawu ya anti-dust adhesion ya antswa.

- Ku kamberiwa ka Vuyelo bya Electrostatic Adsorption: Leswi ku adsorption ka ntshuri ku talaka ku nyanyisiwa hi gezi ra static, surface resistivity na nkarhi wa electrostatic decay na swona swifanele ku kamberiwa ku hambanyisa loko mbuyelo wuvangiwa hi ti khemikhali anti-sticking kumbe electrostatic adsorption.

 

5. Ku seketela Ndzavisiso wa ku Tiyisela

 

- Endzhaku ka ku dyuhala ka mahiselo yale henhla (xikombiso, eka 260°C kumbe 300°C) kumbe friction/wear (Taber abrasion), contact angle leyi boxiweke laha henhla, peel force, na swikambelo swa vuswikoti byo basisa swa phindha-phindhiwa ku tiyisisa leswaku matirhelo yanga onhi ngopfu hinkarhi waku tirhisiwa nkarhi woleha.

Loko u lava ku dyondza swo tala hi tipharamitha leti nga na vuxokoxoko, swiyimo swa ku tirhisiwa, na tindlela to endla hi ku landza swilaveko swa hina eka nxaxamelo wa hina hinkwawo wa switirhisiwa—ku katsa na lapi ra fiberglass leri funengetiweke hi PTFE, thepi ya fiberglass leyi funengetiweke hi PTFE, mabandhi ya fiberglass mesh lama funengetiweke hi PTFE, mabandhi lama nga na swirhabyani lama bohiweke hi namarhela, lapi ra PTFE ra tlhelo rin’we, conveyor leyi nga tiyiseriki mahiselo ya le henhla mabandhi, ni lapi ra fiberglass leri nga ni mahiselo lamakulu—hi kombela u ntshunxeka ku hi tihlanganisa:
