Hauv thaj chaw ntawm cov khoom siv hluav taws xob rwb thaiv tsev, SMC thiab GPO-3 yog ob qho kev xaiv uas feem ntau sib txawv ntawm ntau txoj hauv kev. Hauv tsab ntawv tshaj tawm blog no, peb yuav tshawb nrhiav qhov sib txawv ntawm qhov nthuav dav kom muab kev nkag siab zoo rau koj thaum twg thiab vim li cas koj thiaj xaiv ib qho khoom siv dua lwm tus.
Ua ntej, cia peb txhais txhua yam ntawm cov ntaub ntawv rwb thaiv tsev no. SMC, los yog Sheet Moulding Compound, yog cov khoom siv sib xyaw ua ke los ntawm cov resins, fibers, thiab cov fillers uas yog molded rau hauv cov vaj huam sib luag. GPO-3, ntawm qhov tod tes, yog cov thermoset fiberglass-reinforced polyester cov ntaub ntawv uas muaj nyob rau hauv nplooj ntawv, rods, thiab raj.
Ib qho ntawm cov txheej txheem tseem ceeb uas cov khoom siv no sib txawv yog nyob rau hauv lawv txoj kev tiv thaiv tshav kub thiab hluav taws. SMC tsis yog tshwj xeeb yog hluav taws kub tiv taus thiab muaj qhov ntsuas kub qis ntawm ib puag ncig 130C. Qhov no txhais tau hais tias nws tsis yog qhov zoo tagnrho rau siv nyob rau hauv high-kub los yog hluav taws kub-nyiam ib puag ncig. GPO-3, ntawm qhov tod tes, yog hluav taws kub heev thiab tuaj yeem tiv taus kub txog li 180C. Qhov no ua rau nws muaj kev xaiv zoo dua rau cov ntawv thov uas muaj kev nyab xeeb hluav taws kub ntxhov.
Lwm thaj chaw uas SMC thiab GPO-3 sib txawv yog nyob rau hauv lawv cov khoom siv kho tshuab. SMC paub txog nws lub zog siab thiab nruj, uas ua rau nws muaj kev xaiv zoo rau kev siv cov qauv. Nws kuj tseem muaj kev cuam tshuam zoo heev, uas yog qhov tseem ceeb hauv ib puag ncig uas cov tshuab lossis cov cuab yeej hnyav yuav ua rau muaj kev puas tsuaj. GPO-3, ntawm qhov tod tes, tsis muaj zog lossis nruj li SMC, tab sis nws hloov tau yooj yim thiab tuaj yeem tsim tau yooj yim rau hauv cov duab thiab nkhaus.
Ib qho tseem ceeb sib txawv ntawm SMC thiab GPO-3 yog lawv cov tshuaj tiv thaiv thiab cov kuab tshuaj. SMC yog resistant rau feem ntau ntawm cov organic solvents, uas ua rau nws yog ib tug zoo xaiv rau siv nyob rau hauv ib puag ncig uas muaj tshuaj lom neeg raug. GPO-3, txawm li cas los xij, tsis muaj peev xwm tiv taus cov kuab tshuaj thiab tshuaj lom neeg, thiab kev cuam tshuam ntev tuaj yeem ua rau nws degrade dhau sijhawm.
Hauv kev xaus, thaum ob qho tib si SMC thiab GPO -3 yog cov ntaub ntawv rwb thaiv tsev dav siv, lawv txawv heev ntawm lawv cov khoom thiab kev siv. Yog tias koj xav tau cov khoom siv uas tuaj yeem tiv taus qhov kub thiab txias, GPO-3 yog qhov zoo tshaj plaws rau koj thawj koom ruam. Ntawm qhov tod tes, yog tias koj xav tau cov khoom siv uas muaj zog, tawv, thiab cuam tshuam-resistant, SMC yog qhov kev xaiv zoo dua. Txawm li cas los xij, nco ntsoov ua tib zoo ntsuas koj daim ntawv thov thiab xaiv cov khoom uas ua tau raws li koj cov kev xav tau tshwj xeeb.
