Kev sib piv ntawm SMC cov ntaub ntawv sib xyaw thiab cov ntaub ntawv hlau:
1) Kev coj ua
Cov hlau yog tag nrho cov conductive, thiab cov qauv sab hauv ntawm lub thawv ua los ntawm cov hlau yuav tsum tau insulated, thiab ib qho kev ncua deb yuav tsum tau tso tseg raws li ib qho kev sib cais txoj siv nyob rau hauv lub installation ntawm lub thawv.Muaj qee yam kev xau zais qhov phom sij thiab qhov chaw pov tseg.
SMC yog cov yas thermosetting nrog qhov chaw tiv thaiv ntau dua 1012Ω.Nws yog cov khoom siv insulating.Nws muaj kev ua haujlwm siab rwb thaiv tsev tiv thaiv thiab tawg hluav taws xob, uas tuaj yeem tiv thaiv kev sib tsoo, tuav cov khoom zoo dielectric ntawm qhov siab, thiab tsis cuam tshuam lossis thaiv.Kev nthuav tawm ntawm microwaves tuaj yeem zam qhov hluav taws xob poob ntawm lub thawv, thiab kev nyab xeeb siab dua.
2) Kev tshwm sim
Vim yog qhov ua haujlwm nyuaj ntawm cov hlau, qhov pom ntawm qhov chaw yog qhov yooj yim.Yog tias koj xav ua qee cov duab zoo nkauj, tus nqi yuav nce siab heev.
SMC yog qhov yooj yim rau kev tsim.Nws yog tsim los ntawm cov pwm hlau nyob rau hauv qhov kub thiab txias, yog li cov duab tuaj yeem sib txawv.Qhov saum npoo ntawm lub thawv yog tsim los nrog pob zeb diamond-puab protrusions, thiab SMC tuaj yeem ua xim arbitrarily.Ntau yam xim tuaj yeem kho raws li cov neeg siv khoom xav tau.
3) Nyhav
Lub ntiajteb txawj nqus tshwj xeeb ntawm cov hlau feem ntau yog 6-8g / cm3 thiab qhov tshwj xeeb lub ntiajteb txawj nqus ntawm SMC cov khoom feem ntau tsis ntau tshaj 2 g / cm3.Qhov hnyav qis dua yog qhov tsim nyog rau kev thauj mus los, ua rau kev teeb tsa yooj yim dua thiab yooj yim dua, thiab txuag kev thauj mus los thiab kev teeb tsa zoo heev.
4) Corrosion kuj
Lub thawv hlau tsis tiv taus cov kua qaub thiab alkali corrosion, thiab yooj yim rau xeb thiab kev puas tsuaj: yog tias nws tau kho nrog cov xim xeb, ua ntej ntawm tag nrho cov, nws yuav muaj qee yam cuam tshuam rau ib puag ncig thaum lub sijhawm pleev xim, thiab tshiab. Cov tshuaj tiv thaiv xeb yuav tsum tau noj txhua 2 xyoos.Cov nyhuv xeb-pov thawj tsuas tuaj yeem ua tiav los ntawm kev kho mob, uas ua rau muaj txiaj ntsig zoo ntawm kev kho tom qab kho, thiab nws kuj nyuaj rau kev khiav lag luam.
SMC cov khoom muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv taus corrosion ntawm dej, roj av, cawv, electrolytic ntsev, acetic acid, hydrochloric acid, sodium-potassium compounds, zis, asphalt, ntau yam kua qaub thiab av, thiab kua qaub los nag.Cov khoom nws tus kheej tsis muaj kev tiv thaiv kev laus zoo.Qhov saum npoo ntawm cov khoom muaj cov txheej txheem tiv thaiv uas muaj zog UV tsis kam.Kev tiv thaiv ob zaug ua rau cov khoom muaj kev tiv thaiv kev laus dua: haum rau txhua yam huab cua phem, nyob rau hauv ib puag ncig ntawm -50C - + 150 degrees Celsius, Nws tseem tuaj yeem tuav lub cev zoo thiab txhua yam khoom, thiab qib kev tiv thaiv yog IP54.Cov khoom muaj lub neej ua haujlwm ntev thiab tsis muaj kev saib xyuas.
SMC piv rau lwm cov thermoplastics:
1) Kev laus tsis kam
Thermoplastics muaj kev laus tsis kam.Thaum siv sab nraum zoov rau lub sijhawm ntev, cov phuam yuav raug rau lub teeb thiab los nag, thiab qhov chaw yuav yooj yim hloov xim thiab tig dub, tawg thiab ua nkig, yog li cuam tshuam rau lub zog thiab cov tsos ntawm cov khoom.
SMC yog cov yas thermosetting, uas yog insoluble thiab insoluble tom qab kho, thiab muaj corrosion kuj zoo.Nws tuaj yeem tswj tau lub zog siab thiab zoo zoo tom qab siv sab nraum zoov mus ntev.
2) Khiav
Thermoplastics tag nrho muaj cov khoom nkag.Nyob rau hauv qhov kev txiav txim ntawm lub sij hawm ntev sab nraud quab yuam los yog kev soj ntsuam tus kheej quab yuam, ib tug npaum li cas ntawm deformation yuav tshwm sim, thiab cov khoom tiav yuav siv tsis tau rau lub sij hawm ntev.Tom qab 3-5 xyoos, nws yuav tsum tau hloov tag nrho, ua rau muaj ntau qhov pov tseg.
SMC yog cov khoom siv thermosetting, uas tsis muaj qhov nkag, thiab tuaj yeem tswj nws lub xeev qub yam tsis muaj deformation tom qab siv mus ntev.General SMC cov khoom siv tau tsawg kawg yog kaum xyoo.
3) Rigidity
Cov ntaub ntawv thermoplastic muaj qhov toughness siab tab sis tsis txaus rigidity, thiab tsuas yog tsim rau cov khoom me me, tsis muaj cov khoom thauj khoom, tsis yog rau cov khoom siab, loj thiab dav.
