Cov txheej txheem tsim khoom acrylic

Cov txheej txheem ntau lawm ntawm acrylic zoo ib yam li lwm cov yas, tab sis muaj qhov sib txawv ntawm qhov kub thiab txias thiab cov catalysts ntxiv. Feem ntau muaj peb txoj kev molding: casting, txhaj tshuaj molding, thiab extrusion molding.

Casting molding: Casting molding yuav tsum muaj pwm. Ncuav lub melted acrylic acid rau hauv pwm thiab cia nws sawv ntsug li ob peb teev kom txog thaum nws dhau los ua ib nrab ua ntej nws tuaj yeem tshem tawm ntawm pwm. Tom qab cov ntawv hlau tawm ntawm cov pwm, nws raug xa mus rau lub qhov cub hluav taws xob siab, uas yog cov cuab yeej tshwj xeeb uas ua haujlwm zoo ib yam li lub tshuab hluav taws xob thiab qhov cub. Lub tshuab hluav taws xob siab siv hluav taws xob siv hluav taws xob thiab lub zog kom extrude npuas los ntawm cov yas, ua kom pob tshab thiab ruaj khov. Nyob rau hauv lub qhov cub kub siab, acrylic acid feem ntau yuav siv sij hawm ob peb teev. Tom qab tshem tawm cov tsim acrylic los ntawm lub tshuab hluav taws xob siab, qhov chaw thiab cov npoo yuav tsum tau polished ntau zaus.

Ua ntej, siv cov ntawv xuab zeb me me thiab tom qab ntawd hloov nws nrog cov ntaub mos muag los xyuas kom meej qhov zoo nkauj thiab pob tshab acrylic.

Extrusion molding: Ntxiv acrylic particle raw cov ntaub ntawv rau hauv lub extruder, uas yuav ua kom sov cov ntaub ntawv raw mus rau ib ncig ntawm 150 degree, ua rau lawv khov. Tom qab ntawd nws yog pub ntawm ob lub tshuab nias, thiab cov yas yaj yog flattened rau hauv cov ntawv nyias nyias los ntawm kev siab. Tom qab ntawd cov nplooj ntawv yog txias kom khov cov nplooj ntawv acrylic. Txiav daim ntawv rau hauv qhov loj me thiab txhuam nws ua ntej siv. Extrusion molding tsuas tuaj yeem tsim cov ntawv nyias nyias thiab tsis tuaj yeem tsim lwm cov duab lossis cov ntawv tuab.

Txhaj tshuaj molding: Zoo li lwm yam khoom yas, acrylic kuj tso cov khoom acrylic rau hauv lub plunger lossis ntsia hlau txhaj tshuaj molding tshuab, thiab melts cov ntaub ntawv raw rau hauv paste los ntawm kub. Tom qab ntawd txhaj nws mus rau hauv qhov sib tsoo cov cuab yeej kab noj hniav kom tsim, qhuav nws los ntawm cov cua kub ncig, thiab nws dhau los ua ib qho ruaj khov. Tom qab polishing, nws tuaj yeem siv tau.

Niaj hnub no, kev siv ntawm acrylic yog nce, nce txhua xyoo; Txawm hais tias acrylic yog ib qho ntawm cov yas qub tshaj plaws uas siv niaj hnub no, nws qhov pom kev pom tseeb thiab ua haujlwm rau sab nraum zoov ua rau nws tseem yog cov khoom siv rau ntau daim ntawv thov kev lag luam.
