Kev sib piv ntawm SMC cov ntaub ntawv sib xyaw thiab cov ntaub ntawv hlau:
1) Kev coj ua
Cov hlau yog cov khoom siv hluav taws xob, thiab cov qauv sab hauv ntawm lub thawv ua los ntawm hlau yuav tsum tau rwb thaiv tsev, thiab yuav tsum tau tso ib qho deb li ib txoj siv cais tawm thaum lub thawv teeb tsa. Muaj qee qhov kev phom sij zais thiab pov tseg qhov chaw.
SMC yog ib hom yas thermosetting uas muaj qhov tsis kam ntawm qhov chaw ntau dua 1012Ω. Nws yog ib yam khoom siv rwb thaiv tsev. Nws muaj kev ua haujlwm siab rwb thaiv tsev thiab lub zog tawg, uas tuaj yeem tiv thaiv kev xau, tswj cov khoom dielectric zoo ntawm cov zaus siab, thiab tsis cuam tshuam lossis thaiv. Kev nthuav dav ntawm microwaves tuaj yeem zam kev poob siab ntawm lub thawv, thiab kev nyab xeeb siab dua.
2) Qhov tsos
Vim yog qhov ua cov hlau nyuaj heev, qhov tsos ntawm cov hlau kuj yooj yim heev. Yog tias koj xav ua qee cov duab zoo nkauj, tus nqi yuav nce ntxiv heev.
SMC yooj yim rau kev tsim. Nws yog tsim los ntawm cov pwm hlau nyob rau hauv qhov kub thiab txias siab thiab siab siab, yog li cov duab tuaj yeem tshwj xeeb. Qhov chaw ntawm lub thawv yog tsim los nrog cov pob zeb diamond zoo li pob zeb diamond, thiab SMC tuaj yeem muaj xim raws li qhov xav tau. Ntau yam xim tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
3) Qhov hnyav
Qhov hnyav tshwj xeeb ntawm cov hlau feem ntau yog 6-8g / cm3 thiab qhov hnyav tshwj xeeb ntawm cov khoom SMC feem ntau tsis pub ntau tshaj 2 g / cm3. Qhov hnyav qis dua yog qhov zoo dua rau kev thauj mus los, ua rau kev teeb tsa yooj yim dua thiab yooj yim dua, thiab txuag tau ntau cov nqi thauj mus los thiab kev teeb tsa.
4) Kev tiv thaiv xeb
Lub thawv hlau tsis tiv taus acid thiab alkali corrosion, thiab yooj yim xeb thiab puas tsuaj: yog tias nws raug kho nrog cov xim tiv thaiv xeb, ua ntej tshaj plaws, nws yuav muaj qee qhov cuam tshuam rau ib puag ncig thaum lub sijhawm pleev xim, thiab yuav tsum tau pleev xim tiv thaiv xeb tshiab txhua 2 xyoos. Cov nyhuv tiv thaiv xeb tsuas yog ua tiav los ntawm kev kho mob, uas ua rau tus nqi ntawm kev saib xyuas tom qab ntau ntxiv, thiab nws kuj nyuaj rau kev ua haujlwm.
Cov khoom SMC muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv taus qhov corrosion ntawm dej, roj av, cawv, electrolytic ntsev, acetic acid, hydrochloric acid, sodium-potassium compounds, zis, asphalt, ntau yam acid thiab av, thiab acid nag. Cov khoom nws tus kheej tsis muaj kev ua tau zoo tiv thaiv kev laus. Qhov chaw ntawm cov khoom muaj ib txheej tiv thaiv nrog muaj zog UV tiv thaiv. Kev tiv thaiv ob npaug ua rau cov khoom muaj kev ua tau zoo tiv thaiv kev laus: haum rau txhua yam huab cua phem, nyob rau hauv ib puag ncig ntawm -50C—+150 degrees Celsius, Nws tseem tuaj yeem tswj tau cov khoom zoo thiab cov khoom siv kho tshuab, thiab qib kev tiv thaiv yog IP54. Cov khoom muaj lub neej ua haujlwm ntev thiab tsis tas yuav saib xyuas.
SMC piv rau lwm cov thermoplastics:
1) Kev laus tiv taus
Cov thermoplastics tsis tshua muaj kev laus. Thaum siv sab nraum zoov ntev, daim phuam yuav raug lub teeb thiab nag, thiab qhov chaw yuav yooj yim hloov xim thiab tig dub, tawg thiab ua brittle, yog li cuam tshuam rau lub zog thiab qhov zoo li ntawm cov khoom.
SMC yog ib hom yas thermosetting, uas tsis yaj thiab tsis yaj tom qab kho, thiab muaj kev tiv thaiv corrosion zoo. Nws tuaj yeem tswj tau lub zog siab thiab zoo nkauj tom qab siv sab nraum zoov ntev.
2) Nkag mus
Cov thermoplastics txhua tus muaj cov yam ntxwv creep. Nyob rau hauv qhov kev ua ntawm lub zog sab nraud ntev lossis lub zog kuaj xyuas tus kheej, qee qhov kev hloov pauv yuav tshwm sim, thiab cov khoom tiav lawm tsis tuaj yeem siv tau ntev. Tom qab 3-5 xyoos, nws yuav tsum tau hloov tag nrho, ua rau muaj ntau yam pov tseg.
SMC yog cov khoom siv thermosetting, uas tsis muaj kev nkag mus, thiab tuaj yeem tswj nws lub xeev qub yam tsis muaj kev hloov pauv tom qab siv ntev. Cov khoom SMC feem ntau tuaj yeem siv tau tsawg kawg yog kaum xyoo.
3) Kev Rigidity
Cov ntaub ntawv thermoplastic muaj qhov tawv siab tab sis tsis txaus rigidity, thiab tsuas yog haum rau cov khoom me me, tsis yog-load-bearing, tsis yog rau cov khoom siab dua, loj dua thiab dav dua.
