BMC (Bulk Moulding Compound), SMC (Sheet Molding Compound) thiab DMC (Cov Khoom Siv Moulding Compound) yog tag nrho cov khoom siv thermosetting resin, thiab qhov sib txawv tseem ceeb nyob hauv lawv daim ntawv thiab txheej txheem molding.
1.BMC (Bulk Moulding Compound): BMC yog cov khoom siv thermosetting premixed uas muaj cov resin, iav fiber, muab tub lim, catalyst thiab stabilizer. Nws feem ntau muaj nyob rau hauv daim ntawv thaiv los yog granular, khaws cia rau hauv lub thawv kaw, thiab muab tawm thaum xav tau. BMC feem ntau yog molded los ntawm compression molding, thiab nws cov fluidity zoo heev ua rau nws zoo heev rau kev ua cov high-precision thiab complex Cheebtsam.
2.SMC (Sheet Moulding Compound): SMC yog cov khoom siv ua ntej preg uas tsis yog-kho thermosetting. Thaum siv, nws raug txiav rau hauv cov duab xav tau thiab muab tso rau hauv lub pwm preheated. SMC cov ntaub ntawv muaj ib txheej txheej nyob rau hauv cov resin, thiab cov txheej txheej tiv thaiv cov khoom SMC, uas tuaj yeem tiv thaiv cov khoom los ntawm kev cuam tshuam los ntawm huab cua thaum khaws cia thiab kev thauj mus los. SMC feem ntau yog molded los ntawm compression molding. Qhov zoo heev fluidity thiab expansibility ntawm SMC cov ntaub ntawv ua rau nws tshwj xeeb tshaj yog haum rau ua loj thiab complex qhov chaw.
3.DMC (Dough Molding Compound): DMC yog cov khoom siv thermosetting resin uas muaj kuab heev dua li BMC thiab SMC. Vim lub siab viscosity ntawm DMC, nws muaj cov dej tsis zoo nyob rau hauv lub siab, yog li nws yog feem ntau siv rau phau ntawv molding los yog txhaj tshuaj molding. Kev siv feem ntau suav nrog cov khoom me me lossis cov khoom siv siab.
Tag nrho peb cov ntaub ntawv muaj cov khoom siv hluav taws xob zoo heev, kev tiv thaiv corrosion, qhov ruaj khov thiab lub suab nqus, yog li lawv tau siv dav hauv ntau qhov chaw xws li tsheb, kev tsim kho, khoom siv hluav taws xob thiab khoom siv hauv tsev.
Cov txheej txheem molding ntawm peb cov ntaub ntawv sib xyaw no feem ntau suav nrog ob kauj ruam: molding thiab curing, thiab pwm kub maub los ua lub luag haujlwm tseem ceeb ntawm no. Cov pwm kub maub los, feem ntau yog hais txog pwm pwm kub tswj, uas tuaj yeem tswj qhov kub ntawm pwm kom ntseeg tau tias cov khoom sib xyaw tuaj yeem ua tau zoo thaum lub sij hawm cua sov, compression thiab curing txheej txheem, thiab thaum kawg tsim cov khoom nrog cov qauv ruaj khov thiab tsim nyog. kev ua tau zoo.
