Acrylic xws li suab hauv siab yeej txhaj tshwm nyob rau hauv kev kho kom muaj kev ua tau zoo, uas ua rau lawv zoo rau kev tsim cov ntaub ntawv cuam tshuam uas feem ntau hnub no. Tom qab ntawv, lawv tsis yog yuav luaj li cas tom qab siv dej saum toj ntau zaus. Qhov tseem ceeb ntawm lawv cov ntaub ntawv sib xws yog tias ib qho chaw twg muaj qhov ntxig lossis me me, tuaj yeem hla tso kom ncua, rov qhov sawv los. Cov khoom sib txawv polyester muaj qhov chaw tseem ceeb. Lawv nyob zoo dua thaum muaj kev phom sij, thiab feem ntau muaj tus nqi tsawg dua, tab sis lawv tsis zoo li ntawm kev kho kom rau rau rau qhov chaw nruj. Cov neeg tsim tsev feem ntau xav tau polyester thaum tus nqi yog qhov tseem ceeb dua li cov duab ntxig ntxag, tshpecially rau cov chaw nruj uas tsim nyob rau hauv. Tab sis thaum kev tswj hwm kev noj qab nyob zoo lossis kev cai tseem ceeb, acrylic feem ntau yog leej twg xav tau nyob rau hauv cov chaw pabcuam, chaw tsim khoom noj, thiab chaw ua noj nyob rau hauv.
Kev tau rau kev sib xyaw NSF/ANSI 51 txhais tau tias cov khoom siv los ntawm lub teb chaws no tsis muaj cov pob qhov av uas tuaj yeem pab kom me nyuam ceeb ntxhiab cia thiab sib sau ua feem. Lub teb chaws no txwv tsis pub me nyuam ceeb ntxhiab mus nyob hauv cov qhov av no. Rau cov hospital thiab cov chaw nyob, qhov no yooj yim dua heev kom compared to regular laminate countertops or wooden tables which just soak up dirt over time. Cov teb chaws no kuj tsis tas xav tau cov khoom siv siv sib piv rau lwm yam khoom siv. Ib thauj ntxhua nrog dej thiab sab lo yog tag nrho yooj yim heev. Txhawm rau FSIS tshuaj xyuas los ntawm 2023, cov chaw ua noj ua haus siv cov teb chaws no pom tias lub sijhawm ntxhua nws hlo li ib cuar lossis ib feem pua. Qhov no txhais tau tias txo lub sijhawm rau cov neeg ua haujlwm thiab zoo dua rau kev tshawb xyuas tsev cai. Sib xyeej nrog qhov no nrog qhov yooj yim ntawm kev saib xyuas txhua hnub, tsis muaj dab tsi ua rau ntau chaw nyob hauv ntau yam kev lag luag txaus siab rau cov teb chaws no thaum kev saib xyuas tsev cai yog qhov tseem ceeb tshaj plaws.
Kev tso qhauv digital los ntawm 3D scanning txawj pib peb mus rau ib hlis ntawm millimeter, uas kho kom tsis muaj kev siv ntau qhov chaw uas tuaj yeem tsis zoo rau kev tso. Lub Building Materials Journal piav tseg lawm nyob rau 2023 tias cov chaw tsis sib xws yog ib feem ntawm plaub feem pes tsawg ntawm kev ploj tshuj. Yog li no peb xav tau cov khoom siv tshuab tso nrog tsis tuaj yeem nqus dua li 3mm thaum muab nqi rau. Rau qhov zoo tshaj plaws, siv daim ntawv marine grade plywood lossis cement board ua khoom tshaj tawm. Thiab tsis txhob nrhiav kev check dej kuj! Cov chaw twg muaj dej ntau dua li 4.5% yuav tsum muaj ib daim ntawv sau saum, tshaj tawm tseem ceeb rau qhov chaw uas dej feem ntau nyob. Tus no pab kom tsis muaj kev ploj ntawm kev sau thiab khiav cia ntau ntxiv los ntawm kev tso cai kom tsis muaj kev sau.
Yog xav tau kev txwv tsis muaj qhov chaw, adhesive npib yuav tsum tsis muaj qhov chaw hauv ib cheeb tsam thaum sau tshwj dua ob sab nrog ib qhov tshwj khaub ncaws ua ntej nruab tsiab nrog qhov chaw tseem ceeb ntawm 25 los 30 pounds per square inch. Tsis txhob nrhiav chaw ntau dua li kaum raim ntawm ib lub kaum ntawv hauv ib feeb ntawm 45 feeb vim tias yuav tsum muaj chaw rau kev hloov pauv teeb meem tom ntej. Thaum set ntiag tug, sau nrog 120-grit abrasive thiab rov ua kom sov dua mus rau 800-grit, tom qab ntawd sau nrog polishing kom rov qab muaj xim thiab feel original. Yog tshawj lawm, cov joints no tuaj yeem tso cai ntau dua li 300 heating thiab cooling cycles tsis tas tach. Cov kev sim qhia tias lawv nyob ntev dua ib pliua dua li kev nruab npej method tseem ceeb, yog li qhov appearance zoo dua thiab kev nruab npej zoo dua hauv kev ntsheev siab.
Yog xav tau kev pab los ntawm kev tsim kho acrylic solid surfaces, ces yuav tsum nrhiav kev coj tus cwj pwm tshiab: teeb li cas, sijhawm, thiab kev sau kom muaj form. Yam ntxuav no yuav tsum tau hla rau sab 300 rau 350 degrees Fahrenheit kom pliable tas li, tsis txhob break down. Sijhawm uas nws nyob ntawm tej degrees no yog txiav txim siab los ntawm lub thickness ntawm lub sheet, vim tias cov sheets me me feem ntau yuav muaj bubbling yog tias tso ntev heev. Rau cov molds, CNC machining yog zoo tshaj yog tias muaj 3 degree draft angle, uas pab kom thaum remove lub part tsis tas yam ntxiv. Yog siv cov aluminum molds, yuav tsum tswj lub pressure nyer rau saum 15 rau 20 pounds per square inch kom tswj lub dimensions zoo rau hauv 0.5 millimeter. Thaum cooling lub parts uas tau tsim, thaum twg tseem muaj pressure, yuav tswj kom tsis txhob warping, tiam sis tseem ceeb rau cov duab nyuaj xwb, xws li rounded corners lossis built-in drain boards. Khrim kho yuav tsum ua test samples ua ntej kom paub seb cov molecules tau alight raws li qhov xav tau, thiab kom paub tseeb tias tag nrho yuav tsum zoo ib yam rau txhua batch.
Ib chav tseem fua uas ntev 22 feet nyob rau St. Mary's Regional Medical Center nyob rau Iowa tau qhia tias cov ntaub ntawv solid surfaces uas tau thermoformed tau ua li cas los pab rau kev siv hauv kev pab cuam kho mob. Qhov chav tsim khoom tau siv cov acrylic sheets uas muaj qhov thickness ib hlwb, ua tiab mus rau qhov 325 degrees Fahrenheit ua ntej tsim rau ib qhov mold uas tsim los ntawm cov ntaub ntawv sib txawv. Tom qab ntawd, lawv tau muaj ntau yam kev check kuj tseem ceeb, xws li nrhiav kom muaj NSF/ANSI 51 certification, ua cov kev test 500 cycle abrasion uas nyuaj heev, thiab tshawb xyuas qhov tseem ceeb ntawm kev tiv thaiv kom tsis pub hlawv txav nrog ASTM D5420 standards. Qhov uas tsim qhov kev tsim no zoo tshaj plaws yog qhov tsis muaj qhov chaw sib txuas thiab muaj cov kab ntsug me me uas txhob muaj chaw uas microbes tuaj yeem nyob. Qhov chav saib xyuas kev saj thawb tau hais tias lawv tau sau qhov sijhawm saj thawb cia li 40% dua li cov laminate feem ntau uas lawv tau siv ua ntej. Muaj ntau yam lus kawm los ntawm qhov kev tsim no. Tsis muaj leej twg xav paub tias qhov sijhawm 72-hour tom qab khiav lag yuav tseem ceeb li cas kom tsis pub muaj qhov ntxuav tom qab. Qhov chav tsim khoom kuj paub tias siv infrared thermography pab tso rau qhov ua tiab zoo dua hauv qhov kev tsim. Hauv qhov chaw uas neeg ntau tshaj plaws ntxuav tawm, cov adhesive uas sib xws nrog polymer tau ua haujlwm zoo dua li cov feem ntau. Nrhiav mus rau qhov kev saib xyuas tom qab sijhawm 1.5 xyoo ntawm kev siv hauv hnub hauv hnub, tsis muaj qhov chaw dab tsi lossis qhov ntaub ntawv hlawv, uas qhia tias cov ntaub ntawv no zoo li cas hauv kev siv ntau hauv qhov chaw kho mob uas neeg ntau.
Hom ntawv solid surface feem ntau yog tsim los thiab acrylic resins lossis polyester resins uas tau muab sib chaws nrog alumina tri-hydrate fillers.
Acrylic solid surface muaj qhov tshwm sim zoo dua hauv kev kho form theem nruab nrab, thiab tsis tas li nyuaj ncua, thaum lub polyester surface muaj qhov tiv thaiv zoo dua tiv rau kev phom, thiab feem ntau tsis tas li muaj nuj nqis.
Lub non-porous certification xws li NSF/ANSI 51 nug tias hom ntawv solid surface tsis muaj cov pob me me uas bacteria tuaj yeem cuam tshuam, txhawb qhov nyiaj zoov hauv chaw pab kho mob thiab chaw ua noo.
Kev xaiv yuav xav tau kev nruab qhov template nrog qhov precision, kev txhim kho substrate zoo, kev saib xyuas dej, thiab kev sib sau ntsuas tsis muaj qhov khoov kom paub tias yuav nyob ntev.
