Puas yog lub zog ntawm kev txhaj tshuaj molded yas siab?

1, Lub ntsiab lus ntawm lub zog ntawm kev txhaj tshuaj molded yas
Lub zog ntawm kev txhaj tshuaj molded yas, luv luv, hais txog lub peev xwm ntawm cov ntaub ntawv yas los tiv thaiv kev puas tsuaj thaum raug rau sab nraud. Qhov no suav nrog tab sis tsis txwv rau lub zog tensile, compressive zog, flexural zog, cuam tshuam lub zog, thiab lwm yam. Ntau hom kev txhaj tshuaj molded yas muaj cov yam ntxwv ntawm lub zog sib txawv vim qhov sib txawv ntawm cov qauv molecular, hom thiab cov ntsiab lus ntawm additives, kev ua haujlwm, thiab lwm yam. .
2, Cov yam ntxwv cuam tshuam rau lub zog ntawm kev txhaj tshuaj molded yas
Resin hom: Ntau hom resins muaj cov qauv molecular sib txawv thiab cov khoom siv tshuaj, uas cuam tshuam ncaj qha rau lub zog ntawm kev txhaj tshuaj molded yas. Piv txwv li, nylon (PA) plastics muaj lub zog txhua yam thiab hnav tsis kam vim muaj cov pab pawg polar amide muaj zog hauv lawv cov saw hlau molecular; Polyethylene (PE), ntawm qhov tod tes, muaj lub zog tsis tshua muaj zog tab sis zoo toughness vim nws hloov tau cov saw hlau molecular.
Additives: Txhawm rau txhim kho kev ua haujlwm ntawm kev txhaj tshuaj molded yas, ntau yam khoom siv ntxiv xws li plasticizers, stabilizers, thiab cov khoom siv ntxiv feem ntau yog ntxiv. Hom thiab ntau npaum li cas ntawm cov additives no tuaj yeem cuam tshuam rau lub zog ntawm cov yas. Piv txwv li, qhov sib ntxiv ntawm inorganic fillers xws li iav fiber ntau tuaj yeem txhim kho qhov rigidity thiab lub zog ntawm cov yas.
Cov xwm txheej ua haujlwm: Cov kev ntsuas xws li kub, siab, thiab ceev thaum txhaj tshuaj molding kuj muaj qhov cuam tshuam loj rau lub zog ntawm cov yas. Cov txheej txheem tsim nyog tuaj yeem ncav cuag thiab sib npaug ntawm cov yas molecular chains, yog li txhim kho lub zog ntawm cov khoom.
Tom qab kev kho mob: Cov txheej txheem tom qab kev kho mob xws li kev kho cua sov thiab annealing tom qab txhaj tshuaj molding kuj pab txhim kho lub zog ntawm cov yas. Cov kev kho mob no tuaj yeem tshem tawm kev ntxhov siab sab hauv, txhawb nqa crystallization, thiab lwm yam, ua rau cov khoom ntawm cov yas ruaj khov dua.
3, Kev sim txoj kev rau lub zog ntawm kev txhaj tshuaj molded yas
Txhawm rau txhawm rau ntsuas lub zog ntawm kev txhaj tshuaj molded yas, cov txheej txheem kev ntsuas yuav tsum tau ua. Cov kev sim ntau yam muaj xws li kev sim tensile, kev sim compression, kev sim khoov, kev sim cuam tshuam, thiab lwm yam. Cov kev sim no tuaj yeem simulate tus cwj pwm ntawm cov yas nyob rau hauv cov kev ntxhov siab sib txawv, yog li kev ntsuam xyuas lawv lub zog ua haujlwm.
4, Cov tswv yim los txhim kho lub zog ntawm kev txhaj tshuaj molded yas
Optimizing resin formula: Los ntawm kev kho hom resin thiab additive formula, lub zog tshwj xeeb ntawm kev txhaj tshuaj molded yas tuaj yeem txhim kho raws li lub hom phiaj.
Txhim kho kev siv tshuab: Kev ua kom zoo dua qub xws li kub, siab, thiab ceev thaum txhaj tshuaj molding, nrog rau kev siv cov pwm tsim thiab cua txias, tuaj yeem ua rau kom muaj crystallinity thiab orientation ntawm plastics, yog li txhim kho lawv lub zog.
Ua kom muaj zog tom qab ua tiav: Cov txheej txheem tsim nyog tom qab ua tiav tuaj yeem tshem tawm kev ntxhov siab sab hauv, txhim kho cov khoom sib xws thiab ruaj khov, yog li txhim kho nws lub zog.
Siv cov ntaub ntawv sib xyaw: Los ntawm kev sib txuas cov yas txhaj tshuaj molded nrog lwm cov ntaub ntawv xws li iav fiber, carbon fiber, thiab lwm yam, lub zog thiab tawv tawv ntawm cov yas tuaj yeem txhim kho tau zoo.
5, Daim ntawv thov cheeb tsam ntawm kev txhaj tshuaj molded yas zog
Txhaj tshuaj molded yas tau siv dav hauv ntau qhov chaw vim lawv lub zog siab thiab kev ua haujlwm zoo. Hauv kev lag luam tsheb, kev txhaj tshuaj molded yas yog siv los tsim lub cev, cov khoom siv sab hauv, thiab lwm yam; Hauv kev lag luam khoom siv hauv tsev, kev txhaj tshuaj molded yas tau dhau los ua cov khoom tseem ceeb rau kev tsim cov plhaub thiab cov khoom siv sab hauv; Tsis tas li ntawd, kev txhaj tshuaj molded yas tseem ua lub luag haujlwm tseem ceeb hauv kev ntim khoom, kev tsim kho, kev kho mob thiab lwm yam kev lag luam. Cov ntawv thov no tsis tsuas yog ua kom pom lub zog zoo tshaj plaws ntawm kev txhaj tshuaj molded yas, tab sis kuj tseem ua rau muaj kev vam meej thiab kev loj hlob ntawm lawv cov thev naus laus zis.
