Cov nqes tshuaj rau hauv tsev kawm yuav tsum ua raws li kev xav tsis tau. Nws yuav tsum siv tag nrho tag nrho rau kev siv nyiaj. Nws yuav tsum kho tag nrho tag nrho rau kev kho tshuaj ntau dua. Nws yuav tsum siv rau kev siv cov khoom sov, kev siv cov dej mob, thiab kev siv cov nqes tshuaj uas tuaj los ntawm qhov chaw. Thiab muaj cov neeg nyob hauv chaw uas xav paub tias chaw no puas zoo. Thov koj paub tias cov nqes tshuaj acrylic yuav tsum ua raws li kev xav tsis tau yog qhov zoo dua li cov lwm yam nqes tshuaj.
Granite, quartz, laminate, tile — lawv txhua yam muaj nws lub cim. Timaas rau cov khaab tshoob uas nyob hauv qhov chaw uas muaj neeg ntau, solid surface yog tsis muaj qhov kho (qhuav ntawm dej 0.05%, siv SGS los xyuam), tsis muaj qhov kho (tsis muaj qhov kho lossis qhov kho rau cov bacteria), tu los ntawm chaw (cov qhov kho tu los ntawm chaw), thiab txhob cov kev ceev ntaus NSF/ANSI Standard 51 rau cov khoom siv rau qhov chaw noj. Qhov lus no pib txog qhov chaw uas solid surface yog zoo tshaj plaws rau qhov chaw noj, qhov chaw uas tsis zoo, thiab cov lus xwb rau qhov chaw ua haujlwm ntawm Guangdong Wiselink Ltd. uas cov neeg suav cov khaab tshoob yuav tsum paub.
Qhov chaw tsis muaj qhov kho yog li cas cov bacteria tsis muaj chaw rau nkag mus. Noj qhov tseem ceeb: cov ntaub ntawv uas tsis muaj qhov chaw nyob hauv (solid surface) muaj qhov ntau ntawm dej 0.05% per ASTM D570 testing (SGS tau txhais rau cov Wiselink sheets). Cov dej lossis lwm yam noj mov uas tshuav tsis tau mus rau hauv. Cov tomato sauce, red wine, thiab dej ntawm chicken raw — lawv yuav nyob rau hauv qhov ntaub ntawv mus rau thaum koj saib thiab tshuav tawm. Tshawb xyuas rau granite uas muaj qhov ntau ntawm dej 0.3–0.5% (yog xav tau txhais rau ib zaug ntawm ib xyoo), marble uas muaj qhov ntau ntawm dej 0.5–2% (yog muaj kev ntau dej ces yuav muaj qhov mob), los yog grouted tile uas cov qhov chaw nyob hauv (grout lines) yuav ntau dej tag nrho thiab tsis tuaj yeem kho kom tshwj xeeb. Cov ntaub ntawv uas tsis muaj qhov chaw nyob hauv (solid surface) yog qhov zoo heev rau kev nyab xeeb ntawm kev siv ntaub ntawv.
Kev siv lub code rau kev nyab xeeb yog qhov tswv yim. Ntau qhov chaw nyob rau hauv US, lawv siv lub FDA Food Code, uas txhais tias cov ntsiab ntawm qhov chaw sib sau ntaub ntawv yuav tsum "smooth, non-absorbent, and easily cleanable" (Section 4-101.11). Solid surface yog qhov tswv yim uas muaj cov lus no. Nws kuj muaj NSF/ANSI 51 rau cov khoom siv rau kev sib sau ntaub ntawv—muaj lub tswv yim rau kev sib sau ntaub ntawv tsis muaj kev ploj ntaub ntawv lossis kev ploj duab. Rau cov neeg design rau cov khw tshuaj thiab GCs, qhov no ua kom yooj yim dua rau kev txhawb nqa los ntawm cov neeg saib xyuam kev noj qab haus huv. "Solid surface, NSF certified" yog qhov lus txhawb nqa tshwj xeeb.
Kev xaav tshwj xeeb tsis muaj qhov chaw uas muaj kev ploj ntaub ntawv. Kab tshuab ntsiab thiab kab tshuab hauv qhov rov qab — yog tias nws yog los ntawm qhov ntsiab lossis quartz, muaj qhov txiav ntawm kab tshuab txoj cai thiab kab tshuab txoj cai hauv qhov rov qab. Qhov chaw siv caulk uas yuav ploj los ntawm lub sijhawm. Kab tshuab tshwj xeeb tuaj yeem siv cov cuab yeej kub los txiav thiab tsis muaj qhov txiav rau kab tshuab hauv qhov rov qab. Tsiaj caulk. Tsiaj qhov txiav. Tsiaj dab tsi uas cov bacteria tuaj yeem nyob hauv no. Tsis zoo li no rau qhov chaw nyob ntawm kab tshuab — kab tshuab tshwj xeeb uas siv rau qhov chaw nyob thiab kab tshuab tshwj xeeb tuaj yeem sib xyaw rau kab tshuab ntsiab, ua rau muaj kab tshuab ib qho thiab tsis muaj qhov txiav. Rau hais cov chaw siv kab tshuab rau kev kho qhov tshuab hauv chaw tshuab, qhov no yog qhov yuav muaj kev nyab soom rau kev nyab soom.
Kev tu kom zoo yog qhov kev sau kom muaj ntau dua uas tsis tau pom. Kab tshuab rau chaw tshuab uas muaj 50 tus neeg nyob — muaj qhov tshuab tshwm sim — cov phaeb nyob rau hauv qhov tshuab, cov phaeb stainless steel nyob rau hauv qhov tshuab, cov khoom siv rau kev kho qhov tshuab. Rau granite, qhov tshuab tsis tuaj yeem tshem tawm. Rau kab tshuab tshwj xeeb, siv cov khoom siv 220-grit thiab 15 feeb tuaj yeem tshem tawm. Sau kom zoo dua rau hauv qhov tshuab los ntawm cov khoom siv 400–800–1500 grit, thiab qhov tshuab yuav zoo li qhov tshiab. Rau cov neeg siv chaw tshuab, qhov no yog qhov kab tshuab tuaj yeem sau kom zoo dua rau txoj cai 3–5 xyoo thaum tsis muaj kev kho, thiab tsis yog kho kom zoo dua. Rau 15 xyoo uas siv chaw tshuab, qhov no yog qhov nyuaj.
Cov chaw nyob rau hauv qhov chaw nyob ntawm rooj tsis uas neeg tuaj yuav siv yog xav kom muaj kev txhawb nqa zoo, saib xyuas ntau, thiab nyob tau rau cov lus qhia ntawm kev pab pawg. Solid surface tuaj yeem ua tau ob peb yam no. Cov lus qhia li cas yuav muaj kev siv ntau dua, tab sis yuav raug kho ntau dua. Cov lus qhia dub yuav muaj kev siv ntau dua, tab sis yuav muaj cov ntawv cua ntau dua. Ib qho khaub ncua nyob rau hauv Chicago tau xa cov lus qhia ntawm Wiselink solid surface rau cov bar cocktail rau ib qho khaub ncua uas muaj 7 qhov chaw. Tom qab 18 hnub, peb qhov chaw tau kho cov bar ib zaug — ib qhov kho uas muaj 2 teev thiab tau ua nyob rau hauv lub caij ntuj. Cov bar muaj kev txhawb nqa zoo li thaum kawg.
Cov chaw pab pawg thiab cov chaw pab pawg yuav muaj kev siv ntau thiab ntau yam — cov khoom cua (siv cov khoom pab), cov khoom pab, thiab cov khoom pab. Solid surface yuav muaj kev nyob tau zoo, thiab cov khoom pab uas muaj kev nyob tau zoo yuav muaj kev pab tau zoo tshaj plaws. Cov chaw pab pawg yuav muaj kev pab tau zoo los ntawm kev resistance ntawm cov khoom pab — cov khoom pab rau hauv cov chaw pab yuav muaj kev pab tau zoo. Cov khoom pab ntawm Wiselink tau test rau 1% HCl, bleach, thiab isopropyl alcohol — tsis muaj kev cuam tshuam rau cov khoom pab tom qab 24 teev.
