1.Vim li cas qhov ncaj adhesion tsis zoo?
Tsawg lub zog ntawm cov txheej txheej: Cov txheej txheej du muaj qhov nro qis, ua rau nws nyuaj rau cov nplaum kom ntub dej thiab sib kis, ua rau muaj qhov tshwm sim "tack tack".
Chemical inertness: High -cov txheej txheem zoo (tshwj xeeb tshaj yog PVDF fluorocarbon) yog cov tshuaj lom neeg ruaj khov thiab tsis yooj yim tsim cov tshuaj lom neeg los yog lub cev muaj zog cuam tshuam nrog cov nplaum.
Kev sib kis ntawm qhov chaw: Thaum lub sij hawm tsim khoom, kev thauj mus los, thiab kev khaws cia, cov txheej txheem yuav kis kab mob nrog cov tshuaj tso tawm, roj, lossis plua plav, ua kom tsis muaj zog ntxiv.
Kev ntxhov siab sab hauv thiab kev laus ntawm cov txheej: Thaum lub sij hawm, cov txheej yuav muaj hnub nyoog, chalk, los yog tsim kev ntxhov siab, ua rau tsis ua hauj lwm ntawm cov nplaum nplaum.
2.Yuav ua li cas txheej txheej cuam tshuam adhesion?
PVDF (fluorocarbon) txheej: Feem ntau nyuaj rau daim ntawv cog lus vim nws muaj zog inertness thiab smoothness.
HDP/SMP (silicone{0}}hloov polyester): Nyuaj nyuaj.
Ordinary polyester txheej: Qhov yooj yim tshaj plaws, tab sis tseem yuav tsum tau ua.
3.Yuav ua li cas txheej txheej cuam tshuam rau adhesion?
Tshiab tsim thiab ntxuav: Cov mob zoo.
Hnub nyoog thiab hmoov: Cov hmoov txheej yuav tsum tau muab ntxuav kom huv si, txwv tsis pub ua tsis tiav yog qhov kev zam.
Cov kab mob: yuav tsum tau ntxuav.
4.Yuav ua li cas thiaj ua tau zoo adhesion?
Kev ntxuav tob tob:
Ua tib zoo so nrog cov kuab tshuaj (xws li isopropyl cawv lossis tshuaj ntxuav tshwj xeeb) kom tshem tawm tag nrho cov roj, plua plav, thiab tso tawm tus neeg sawv cev. Tsis txhob tsuas yog yaug nrog dej.
Lub cev Sanding / Roughening (Ntaus pom zoo rau siab -Yuav tsum muaj Bonding):
Siv cov ntawv xuab zeb zoo (piv txwv li, 180-400 grit) los yog cov ntaub qhwv ntsej muag kom sib npaug ntawm cov xuab zeb coated ntawm cov cheeb tsam yuav tsum tau sib koom ua ke kom txog thaum lub gloss ploj mus, nthuav tawm cov xim zoo nkauj.
Lub hom phiaj: txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam.
Kev Tu Tom ntej: Tom qab xuab zeb, tshem cov xuab zeb nrog cov kuab tshuaj.
5.Dab tsi yog qee cov lus qhia txog kev thov thiab kev ceev faj?
Rau qhov tsis yog - tseem ceeb, tsis yog - thauj khoom- cov kabmob (xws li cov cim kos npe thiab cov khoom siv zoo nkauj me me): Tom qab ua kom huv si thiab xuab zeb, siab - lub zog VHB ob npaug - daim kab xev (hom xws li 3M) tuaj yeem siv. Nws yog tsim tshwj xeeb rau cov coatings uas tsis tshua muaj zog thiab yooj yim rau kev thov.
Rau kev thauj khoom tseem ceeb-cov qauv kabmob (xws li cov txheej txheem rwb thaiv tsev thiab cov khoom siv ntxiv): Ib txoj hauv kev "sanding + specialized structural adhesive" yuav tsum tau siv, nrog rau cov qauv kuaj thiab rub- tawm cov kev xeem kom paub tseeb tias qhov adhesion ua tau raws li cov qauv tsim.
Qhov xwm txheej phem tshaj plaws: Yog tias kev sib txuas rau cov laus, cov txheej txheem chalked, cov txheej txheem chalked yuav tsum tau muab xuab zeb tag nrho kom txog thaum cov txheej txheej tau nthuav tawm; txwv tsis pub, daim ntawv cog lus yuav inevitably poob.
