(IV) tus yam ntxwv ntawmEpoxy Resin Adhesive
1. Epoxy cov nplaum nplaum yog ua raws cov kabmob epoxy ntawm kev rov ua dua tshiab, yog li nws cov kev ua tau zoo, yog li nws cov kev ua tau zoo, yog li nws cov tshuaj txhuam ntxiv nrog txhawm rau siv, thiab yuav tsum tau Sib xyaw ua ke nyob rau hauv thiaj li yuav tau txais kev kho kom zoo, feem ntau epoxy resin adhesive hu ua cov kua nplaum lossis tus neeg sawv cev tseem ceeb, tus kws kho mob hu ua b lours lossis tus neeg saib xyuas tus neeg saib xyuas (tawv tawv).
2. Xav txog cov yam ntxwv tseem ceeb ntawm Epoxy Resin Adhesive ua ntej kev kho khoom ua ntej kev kho mob yog: xim, siv tau lub sijhawm, tsis txhob pom lub sijhawm, thixotropy (tsis txhob pom lub sijhawm), hardness, hardness, sab nro thiab lwm yam. Viscosity (viscosity): yog sab hauv kev sib txhuam ntawm cov ndaws hauv qhov dej, nws tus nqi yog txiav txim siab los ntawm hom khoom, kub thiab lwm yam.
Gel lub sij hawm: kev kho cov kua nplaum yog cov txheej txheem ntawm kev hloov pauv ntawm cov kua nplaum rau lub sijhawm ua rau lub sijhawm gel, uas tau txiav txim siab los ntawm cov kev sib xyaw ntawm epoxy cob qhia Kua nplaum, ntsuas kub thiab lwm yam.
Thixotropy: Tus cwj pwm no yog hais txog colloid kov los ntawm sab nraud quab yuam (rhawv, txheej txheem sab nraud los nres lub luag haujlwm ntawm lub luag haujlwm rov qab mus rau tus thawj thaum Lub sib xws ntawm cov tshwm sim.
Kev nyuaj: Hais txog qhov tsis kam ntawm cov khoom siv rau sab nraud rog xws li embossing thiab khawb. Raws li cov kev ntsuas sib txawv ntawm ntug dej (Ntughe) Hardness, Brinell (Rockwell) Hardness, Pob Ntsig) Hardness, Vichers (Vichers) Hardness thiab. Tus nqi ntawm lub hardness thiab hom hardness ntaus cuam tshuam nrog cov qauv kev kuaj xyuas tawv me me, cov hom neeg taug kev hardness tuaj yeem faib ua hom, C Hom, A-hom rau ntsuas cov mos Colloid, C thiab D-hom rau kev ntsuas ntawm ib nrab thiab nyuaj colloid.
Cov nro: Qhov kev nyiam ntawm cov molecules nyob rau hauv cov kua kom cov molecules nyob rau sab hauv lub zog, lub zog no ua rau muaj kev sib tw mus rau saum npoo ntawm lub zog, hu ua nro. Los yog kev sib nrig sib sib txuas nruab nrab ntawm ob qho chaw nyob ib sab ntawm cov kua rau ib ntu ntev, nws yog qhov ua kom muaj zog ntawm molecular quab yuam. Chav ntawm thaj npoo nro yog n / m. Qhov loj ntawm cov nro muaj feem cuam tshuam nrog xwm, huv thiab kub ntawm cov kua.
3. Xav txog cov yam ntxwv ntawmEpoxy Resin AdhesiveTom qab kho cov yam ntxwv tseem ceeb yog: kev nqus, voltage, cua sov, tshuaj kub kev ntxhov siab, elongation, shrinkage coefficient , Thermal conductivity, kev cog lus hluav taws xob, huab cua, kev laus tsis kam, thiab lwm yam.
Kev tiv: Piav qhia cov khoom siv tiv thaiv feem ntau nrog cov nplaim dej tsis taus lossis ntim tiv taus. Deg tsam yog tsuas yog tib qho saum npoo ntawm ob electrodes ntsuas tus nqi tiv, chav ntsuas yog ω. Cov duab ntawm electrode thiab tus nqi tiv taus tuaj yeem suav tau los ntawm kev sib txuas ntawm qhov chaw ntawm thaj chaw. Cov ntim tsis kam, tseem hu ua kev tiv thaiv tsis taus, yog qhov ntsuas tau tus nqi tiv thaiv cov khoom siv hluav taws xob ntawm directic lossis cov ntaub ntawv insulating lossis insulating. Nws yog qhov tseem ceeb index kom paub cov hluav taws xob hluav taws xob ntawm dielectric lossis insulating cov ntaub ntawv. 1cm2 dielectric tsis kam rau to freakage tam sim no, chav tsev yog ω-m lossis ω-cm. Qhov loj dua cov tsis kam tiv thaiv, qhov zoo dua cov khoom lag luam insulating.
Ntawv Pov Thawj Hluav Taws Xob: Kuj paub tias yog tiv thaiv voltage zog (lub zog ntawm voltage), qhov ntau dua tus nqi nyob rau hauv cov khoom siv hluav taws xob, qhov ntau yuav ionize kev sib tsoo, ua rau muaj Qhov kev sib tawg ntawm colloid. Ua kom cov insulator puas ntawm qhov chaw voltage qis tshaj yog hu ua cov khoom ntawm qhov kev tawg no. Ua 1 Mm tuab insulating cov cuab yeej rhuav tshem, yuav tsum tau ntxiv cov khoom siv hluav taws xob nrog lub zog voltage withstand, chaw nyob yog: KV / hli. insulating cov khoom rwb thaiv tsev thiab kub muaj kev sib raug zoo. Qhov siab dua qhov kub, qhov tsis zoo ntawm cov rwb thaiv tsev rwb thaiv tsev ntawm cov khoom siv insulating. Txhawm rau kom ntseeg tau lub rwb thaiv tsev muaj zog, txhua cov ntaub ntawv insulating muaj qhov kev ua haujlwm uas muaj qhov ntsuas kub, tuaj yeem siv tau kev nyab xeeb rau lub sijhawm ntev, ntau dua qhov kub no yuav tau txais kev laus sai sai.
Dej ragentit: Nws yog kev ntsuas ntawm qhov uas ib qho khoom siv uas nqus dej. Nws yog hais txog qhov feem pua nce nyob rau hauv huab hwm coj ntawm cov tshuaj tov rau hauv dej rau ib lub sij hawm ntawm lub sijhawm ntawm ib qho kub.
Lub zog tensile: Tensile lub zog yog qhov siab tshaj plaws kev ntxhov siab thaum lub gel tab tom ncav cuag. Kuj tseem muaj lub zog tensile quab yuam, tensile lub zog, tensile lub zog, tensile lub zog. Chav tsev yog mpa.
Tawv muaj zog: Kuj tseem hu ua Shear lub zog, yog hais txog qhov chaw sib raug zoo tuaj yeem tiv thaiv qhov siab tshaj plaws thauj mus rau thaj chaw ntawm MPA.
Tev lub zog: tseem hu ua tev lub zog, yog qhov siab tshaj plaws kev puas tsuaj thauj ib chav dav yuav tiv taus, yog kev ntsuas ntawm txoj kab kev quab yuam muaj peev xwm, chav tsev yog kn / m.
Elongation: Hais txog qhov colloid nyob rau hauv lub tensile quab yuam nyob rau hauv kev txiav txim ntawm qhov ntev ntawm kev nce hauv qhov ntev ntawm feem pua.
Thaum tshav kub kub deflection kub: Hais txog kev ntsuas ntawm cov cua sov tsis kam ntawm kev kho cov khoom siv hluav taws xob, ntsuas cov khoom siv phom sij Mus txog qhov tau teev tseg ntawm qhov ntsuas kub, uas yog, cov cua sov deflect kub, xa mus rau raws li cov cua sov deflection kub, lossis hdt.
Cov iav hloov cua txias: Hais txog cov khoom siv kho tau los ntawm cov iav ua haujlwm rau cov amorphous lossis kua ntawm qhov kev hloov pauv ntawm lub xeev) ntawm qhov kev hloov pauv ntawm nruab nrab (lossis qhov txawv txav TG, yog qhov ntsuas ntawm cov cua sov ua kom tsis kam.
Shrinkage kev siv: txhais raws li feem pua ntawm qhov sib piv ntawm shrinkage mus rau qhov loj me ua ntej shrinkage, thiab shrinkage yog qhov sib txawv ntawm qhov loj me ua ntej thiab tom qab shrinkage.
Sab hauv kev ntxhov siab: Hais txog qhov tsis muaj sab nraud rog, cov khoom siv) vim tias muaj qhov tsis xws luag, cov khoom siv kub, thiab lwm yam laj thawj rau kev ntxhov siab sab hauv.
Tshuaj Kuj: Hais txog kev muaj peev xwm tiv taus cov kua qaub, alkalis, ntsev, cov kuab tshuaj thiab lwm yam tshuaj.
Nplaim tsis kam: Hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv kev sib txuas ua ke thaum sib chwv nrog cov nplaim taws los yog cuam tshuam ntawm kev sib txuas ntxiv thaum deb ntawm nplaim taws.
Huab Cua Kuj: Hais txog cov khoom raug rau hnub ci, cua sov thiab txias, cua thiab nag thiab lwm yam huab cua huab cua.
Kev ua laus: Kho colloid nyob rau hauv kev ua, cia thiab siv cov txheej txheem, vim muaj pa, kev hloov kho lub cev, thiab tshuaj lom neeg, yog li cov Polymer Cov Khoom Siv Crosslinking Brittle, tawg cov nplaum, cov ntxhib liab vog, kev ua haujlwm ntawm kev poob ntawm cov neeg tsis tuaj yeem siv, qhov tshwm sim no yog hu ua kev laus. Qhov tshwm sim ntawm qhov kev hloov no yog hu ua kev laus.
Dielectric tas li: Kuj tau paub tias yog tus nqi capacitance tus nqi, tus nqi tsim txom (tso cai). Hais txog txhua lub "ntim ntim" ntawm cov khoom, nyob rau txhua qhov ntawm "lub zog tiav" tuaj yeem txuag "electrostatic lub zog" (electrostatic lub zog) ntawm cov ntau npaum li cas. Thaum lub pob zeb "permeability" qhov ntau dua (uas yog, qhov nyuaj kom ncav cuag cov nyhuv ntawm cov kev ua tiav tag nrho, hauv lwm lo lus, cov khoom lag luam ntau dua to. Yog li ntawd, tus dielectric constant ntawm insulating cov ntaub ntawv nyob rau hauv dav dav, tus me dua zoo dua. Tus dielectric constant dej yog 70, noo noo noo, yuav ua rau muaj kev hloov pauv tseem ceeb.
4. Feem ntau ntawm covEpoxy Resin Adhesiveyog tshav kub-teeb ua nplaum, nws muaj cov yam ntxwv tseem ceeb hauv qab no: Qhov siab dua qhov ntsuas kub dua ntawm kev kho kom sai; ib qho kev sib xyaw ntawm cov kev kho kom sai dua; Tus txheej txheem kev txuag tau muab qhov tshwm sim exothermic.
