Kev tsim cov khoom siv uas muaj txoj haujlwm zoo: Los ntawm cov khoom siv raw rau cov khoom siv uas tau tsim lawm

Qhov kev piav qhia ntawv pov thawj

Ua paub li cas uas ua kom muaj cov ntawv kam noj ntawv tshuaj yuav pab cov neeg xa khoom txhawb rau kev txheeb xyuam cov neeg xa khoom, tso cov kev xav txog lub sijhawm uas yuav tau khoom, thiab nrhiav cov lus qhia rau qhov zoo. Kev ua hauj lwm no muaj peb zaug loj: txhawb cov khoom siv raw, ua kom muaj qhov tshuaj, ua kom muaj qhov tshuaj ntau, txhawb qhov tshuaj los ntawm qhov tshuaj, sau thiab ua kom zoo, thiab txheeb xyuam qhov zoo. Txhua zaug yuav sib kis rau qhov zoo ntawm cov ntawv.

Zaug 1: Txhawb cov khoom siv raw

Kev ua hauj lwm no pib ntawm ob qhov khoom siv loj:

Resin: PMMA (acrylic pure) lossis PMMA/UPR blend (acrylic modified) — feem ntau yog 30–40% ntawm qhov kev ua

ATH (alumina trihydrate): Cov khoom siv khoob uas tau sau los — 60–70% ntawm qhov kev ua

Cov khoom siv ntxiv tau muaj: cov ntawv (rpuas sib kis), cov khoom ua kom muaj qhov tshuaj (ua kom muaj qhov tshuaj), cov khoom ua kom muaj qhov tshuaj los ntawm qhov tshuaj, cov khoom ua kom muaj qhov tshuaj tsis tuaj yeem rau qhov roj (UV stabilizers), thiab cov khoom siv ntxiv rau cov qhov tshuaj sib kis (anti-static, anti-bacterial).

Cov ntawv tshuaj yog muab loj, muab rau hauv cov kab mob, thiab muab txuas rau hauv cov txuas tshuaj uas muaj qhov siab heev los ntawm thaum kws txuas tau zoo. Qhov teeb meem ntawm qhov sib npaug ntawm qhov txuas thiab qhov ceev yog txuas nrog qhov sib npaug ntawm li cas thiab qhov tsis muaj qhov tawg.

Kab 2: Tshuaj tshuaj

Cov tshuaj tshuaj yog muab tshuaj rau hauv cov kab mob. Muaj ob lub tshuaj:

Tshuaj tshuaj rau hauv kab mob: Cov tshuaj tshuaj yog muab tshuaj rau hauv cov kab mob (txwv tsis 3050×760 mm lossis 3680×760 mm) rau hauv cov kab mob tshuaj tshuaj. Cov kab mob txhua yam yog muab tshuaj kom muaj qhov tshuaj tshuaj kom txhawj tshuaj tshuaj.

Tshuaj tshuaj tshuaj: Cov tshuaj tshuaj yog muab tshuaj rau hauv cov kab mob tshuaj tshuaj uas muaj qhov tshuaj tshuaj. Txoj kev no yog muab tshuaj tshuaj rau hauv cov kab mob tshuaj tshuaj, tab sis yuav tsum muaj qhov tshuaj tshuaj tshuaj tshuaj tshuaj.

Wiselink siv cov tshuaj tshuaj rau hauv cov kab mob tshuaj tshuaj — qhov no yog muab tshuaj tshuaj tshuaj rau hauv cov kab mob tshuaj tshuaj thiab cov kab mob tshuaj tshuaj.

Kab 3: Tshuaj tshuaj

Cov kab mob tshuaj tshuaj yog muab tshuaj rau hauv cov kab mob tshuaj tshuaj. Cov kab mob tshuaj tshuaj yog muab tshuaj rau hauv cov kab mob tshuaj tshuaj kom muaj qhov tshuaj tshuaj tshuaj.

Curing parameters:

Thermal temperature: 60–90°C (txhawb rau hauv qhov roj thiab qhov loj)

Hli: 30–90 feeb (txhawb rau hauv qhov loj — 12 mm yuav tsum siv ntau dua 6 mm)

Atmosphere: Controlled temperature and airflow

Pure acrylic requires a longer, more carefully controlled cure than modified acrylic. Rushed curing creates internal stress that manifests as warping or micro-cracking.

Kab 4: Tshem cov ntaub ntawv

Tom qab curing, cov ntaub ntawv yuav tsum sov ua ntej tshem cov ntaub ntawv. Soov ntau yuav pab cuam tshuam rau thermal shock thiab qhov ntaub ntawv yuav tsum sov mus rau hauv qhov sov ntawm lub zog 2–4 teev.

Tom qab tshem cov ntaub ntawv, cov ntaub ntawv yuav muaj qhov ntsiag ntsiag (los ntawm cov ntaub ntawv) thiab qhov ntsiag zoo dua (los ntawm cov ntaub ntawv).

Kab 5: Soov thiab finishing

Cov ntaub ntawv yuav tshem mus rau hauv qhov soov ntau kab:

Sanding tshuas (60–80 grit) — txhawb cov ntawv, tshem tshuas cov ntaub qhia

Sanding tshuas nyob rau hauv (120–180 grit) — ua kom zoo siab

Sanding tshuas zoo (240–400 grit) — tshem tshuas rau kev ua ntev

Kev ua ntev thaum kawg — ua kom muaj kev zoo siab (satin) lossis kev zoo siab tshaj plaws

Cov kev sib piv ntawm qhov loj yuav tsum yog ±0.2 mm rau 12 mm ntawv tom qab sawv. Cov neeg ua haujlwm zoo tshaj plaws ua raws li kev sib piv zoo dua.

Kab 6: Kev saib xyuas qhov zoo

Txhua lub nqaij yog qhia kom paub rau:

Cov kab rov tav (siv cov khoom siv los ntsuas rau cov cim puv)

Cov ntsiab lus zoo (qhia kom paub los ntawm kev saib xyuam rau hauv cov txheej txheem ntawm kev saib xyuam)

Cov qhov tsis zoo ntawm cov nqaij (cov qhov tawg, cov qhov tswv, cov qhov kha, thiab cov ntaub ntawv)

Cov kev nyuaj thiab cov kev nyuaj (siv cov nqaij los ntsuas rau txhua qhov)

Cov kev nyuaj ntawm kev tso cua (siv cov nqaij los ntsuas rau txhua qhov ua tau)

Wiselink muab cov nqaij mus rau cov neeg siv tau nrog cov leej twg thiab cov ntsiab lus uas tuaj yeem txhawb tau rau cov ntsiab lus ntawm kev ua tau thiab cov cim ntawm kev ua tau

Cov sij hawm ua tau los ntawm qhov (txwv)

FAQ

Q: Yog li cas uas ua rau cov neeg ua tau zoo ib yam li cov neeg ua tau tsis zoo? A: Peb yam: (1) cov kab rov tav — cov neeg ua tau zoo tuaj yeem txhawb ±0.2 mm lossis zoo dua, (2) cov ntsiab lus zoo rau txhua qhov ua tau, thiab (3) cov sij hawm ntsuas cov nqaij — cov neeg ua tau zoo ntsuas rau txhua qhov, tsis yog rau txhua hnub.

Q: Yuav muaj cov liab uas tsim los ntawm kev tsim kho tshiab rau cov khoom uas muaj qhov loj leej twg? A: Cov liab uas tsim kho tshiab yuav tsum muaj kev tsim kho hauv lub tsev kawm thiab kev saib xyuam rau cov khoom tsim kho. Qhov ntau tshaj plaws yog 100+ lub ntawv rau kev tsim kho tshiab uas muaj kev siv tau zoo.

Q: Kuv yuav ua li cas kom paub tias cov neeg tsim kho muaj kev qhia tias cov khoom muaj quality? A: Thov: cov lus qhia txog cov khoom (sib sau rau ASTM/ANSI test results), cov duab ntawm cov khoom tsim kho, cov lus qhia txog kev saib xyuam quality, thiab cov khoom tsiab los ntawm kev tsim kho nyob rau hauv no. Cov duab video uas muaj kev saib xyuam lub tsev tsim kho kuj yog qhov tseem ceeb.
