Jiangsu Aokai Cov Khoom Tshiab, cov chaw tsim khoom ntawm PTFE cov ntaub ntawv kub kub, muab kev tshuaj xyuas qhov tob. Matt sanding kev kho mob coj cov kev hloov pauv tseem ceeb rau cov qauv saum npoo ntawm PTFE cov ntaub kub kub. Nws hloov qhov qub ultra-inert, ultra-smooth nto mus rau hauv ib qho kev sib koom ua ke, yooj yim wettable functional nto los ntawm peb qhov ntev: lub cev morphology, txheej kev ncaj ncees thiab tshuaj lom neeg lub xeev.
1. Microscopic Morphology: Los ntawm Daim iav Smooth mus rau Rough Gully Texture Qhov chaw tsis kho ntawm PTFE high-temperature daim ntaub yog tus du nyob rau hauv microscopes, tsim los ntawm ib tug nruam zaj duab xis ntawm yaj-sintered polytetrafluoroethylene. Sanding kev kho mob drastic hloov nws micro-morphology:
· Nthuav nce nyob rau hauv qhov chaw roughness: Mechanical sanding (abrasive siv, steel hlau txhuam) los yog xuab zeb blasting (corundum, dawb fused alumina) txiav thiab cuam tshuam rau saum npoo, carving countless micro-grooves, pits thiab peaks. Core roughness indicators Ra (arithmetical txhais tau tias sib txawv ntawm qhov kev ntsuam xyuas profile) thiab Rz ( kaum-point qhov siab ntawm irregularities) ntau heev.
· Tsim cov qauv kev sib tsoo tshuab: Cov micro-grooves no tsis yooj yim khawb, tab sis 3D interlocking qauv. Qhov no yog qhov tseem ceeb ntawm cov nyhuv anchoring: adhesives nkag mus rau hauv cov khoob no thiab kho kom tsim lub cev sib cuam tshuam rau kev sib txuas tom ntej lossis txheej txheej.
· Hloov qhov sib npaug ntawm qhov sib xws: Sanding kom zoo muab ib qho matte tiav. Kev tswj cov txheej txheem tsis raug ua rau thaj chaw tshaj xuab zeb (hloov txheej txheej hnyav) thiab cov thaj ua rau thaj tsis sib haum, ua rau muaj qhov tsis sib xws ntawm cov txheej txheem sib txawv.
2. Coating Integrity: Los ntawm cov yeeb yaj kiab tsis tu ncua mus rau kev puas tsuaj, nthuav tawm substrate Qhov no yog qhov tseem ceeb tshaj plaws uas yuav tsum tau tswj cov txheej txheem nruj, ncaj qha txiav txim siab qhov kev pabcuam tseem ceeb ntawm cov khoom:
· Thinning ntawm PTFE txheej: Sanding yog qhov tseem ceeb ntawm kev tshem tawm cov khoom siv lub cev. PTFE txheej ntawm cov ntaub kub kub feem ntau yog li ntawm kaum mus rau pua pua microns tuab. Cov xuab zeb ntau dhau ua rau txo cov txheej tuab, txo qis dielectric zog thiab tshuaj lom neeg corrosion kuj ua haujlwm lub neej.
· Kev pheej hmoo ntawm cov fiberglass substrate (qhov teeb meem loj tshaj plaws): Thaum sib tsoo qhov tob tshaj lub thickness ntawm PTFE txheej, lub hauv paus fiberglass ntaub yuav abraded, ua rau ib tug series ntawm tsis ua hauj lwm:
1. Kev poob ntawm cov khoom uas tsis yog-stick: Cov iav fibers tuaj yeem ua raws li cov khoom siv;
2. Moisture thiab tshuaj nkag mus: Dej vapor thiab tshuaj infiltrate cov ntaub ntawm capillary txiav txim ntawm iav fibers, ua rau delamination thiab sai degradation;
3. Txo cov neeg kho tshuab lub zog: Kev puas tsuaj ntawm cov iav fibers ua rau lub zog tensile ntawm tag nrho cov ntaub.
· Tsim cov microcracks thiab cov khoom khib nyiab: Abrasive txiav ntawm PTFE muab cov pob txha tawg thiab cov kua muag tawg, tsim cov microcracks thiab burrs raws cov npoo npoo thiab hauv qab. Lub caij no, stripped PTFE chips tuaj yeem rov tso nyiaj xoob ntawm qhov chaw, tsim cov kob zoo li cov qauv xoob uas cuam tshuam qhov kev ntseeg tau ntawm cov txheej tom ntej lossis kev sib txuas.
3. Surface Chemical State: Los ntawm Ultra-Inert mus rau Activated Txawm hais tias sanding feem ntau yog kev kho lub cev, nws kuj ua rau muaj kev hloov pauv rau cov khoom siv tshuaj lom neeg:
· Elevated nto zog: Pure PTFE muaj ultra-low nto zog (18-20 mN / m), nrog dej sib cuag lub kaum sab xis tshaj 108 °. Tom qab xuab zeb, tshiab tsim rough nto thiab tawg molecular chains ib ntus nthuav tawm high-zog active chaw, lifting nto zog tshaj 40 mN / m. Cov tee dej sib kis thiab ntub dej ntawm qhov chaw, uas qhia txog kev siv dej ib ntus, uas maj mam ploj mus dhau sijhawm.
· Kev taw qhia ib ntus ntawm pawg polar functional: High-zog sib tsoo ua rau muaj kev cuam tshuam ntawm tawg PTFE molecular chains thiab oxygen / noo noo nyob rau hauv huab cua, instantly tsim polar functional pawg xws li carbonyl (C = O) thiab hydroxyl (-OH). Cov pab pawg no tso cai rau kev sib txuas tshuaj rau kev hloov kho tshuaj ntxiv lossis cov nplaum lamination.
Cov ntsiab lus ntawm tag nrho cov cuam tshuam Nyob rau hauv luv luv, ib tug tsim nyog sanding kev kho mob tsim ib tug niaj hnub, ntxhib, activated micro-nano qauv ntawm PTFE daim ntaub tsis ua puas lub hauv paus fiberglass substrate.
· Kev hloov pauv zoo: Tsim cov khoom siv sib cuam tshuam kev ntxhib los mos los daws PTFE qhov teeb meem tsis zoo ntawm qhov adhesion.
· Tsis zoo drawbacks: txis thawj tsis-stick kev ua tau zoo, nto smoothness thiab pob tshab, nrog tas mus li txaus ntshai ntawm substrate puas thiab shortened kev pab cuam lub neej.
Yog li ntawd, lub hauv paus tseem ceeb ntawm cov txheej txheem no nyob rau hauv kev tswj kom meej ntawm cov khoom tshem tawm qhov tob - tsuas yog sab saum toj PTFE txheej txheej yog abraded, tsis kov lub fiberglass reinforcement pob txha. Cov ntaub kho mob feem ntau yog xa mus rau txheej txheej lossis kev sib txuas ua ke tam sim ntawd kom tau txais txiaj ntsig zoo ntawm nws qhov pom kev zoo tshaj plaws hauv lub xeev.
