Nonwoven fabrics kuj muaj lawv tus kheej txoj kev ntsuas rau thickness thiab hnyav. Feem ntau, thickness yog xam nyob rau hauv millimeters, thaum hnyav yog xam nyob rau hauv kilograms los yog tons. Cia wb mus saib cov ncauj lus kom ntxaws kev ntsuas rau thickness thiabhnyav ntawm non-woven fabrics.
Kev ntsuas txoj kev rau cov ntaub tsis-woven
Txhua yam khoom muaj qhov hnyav, ib yam li cov ntaub tsis-woven peb tab tom tham txog niaj hnub no. Yog li yuav ua li cas xam qhov hnyav ntawm cov ntaub tsis-woven?
Hauv kev suav ntawm qhov hnyav thiab qhov hnyav ntawm cov ntaub tsis-woven, plaub chav nyob feem ntau yog siv: ib qho yog lub vaj, abbreviated li Y hauv lus Askiv; Qhov thib ob yog meters, abbreviated li m, qhov thib peb yog grams, abbreviated li grams, thiab lub thib plaub yog millimeters, abbreviated li mm
Kev xam ntev
Nyob rau hauv cov nqe lus ntawm specifications, ob qho tib si loj thiab meter yog siv los xam qhov ntev. Hauv kev tsim cov ntaub tsis-woven, ' meter ' feem ntau yog siv los ua chav tsev ntawm qhov ntev, thiab qhov ntsuas ntawm qhov ntev muaj xws li meters, centimeters, millimeters, thiab lwm yam. Vim lub fact tias cov non-woven fabrics dov ib tug los ntawm ib tug, qhov siab ntawm yob yog hu ua dav, qhia nyob rau hauv meters. Feem ntau siv tshwj xeeb yog 2.40 meters, 1.60 meters, thiab 3.2 meters. Piv txwv li, hauv cov txheej txheem ntawm kev tsim cov ntaub tsis-woven, txhua txoj kev tsim khoom yuav muaj qhov ntev, xws li "tsim X meters ntawm cov ntaub tsis-woven hauv ib lub tshuab molding".
Kev xam qhov hnyav
Vim tias muaj qhov ntev thiab qhov dav, puas muaj qhov tuab? Yog lawm, muaj. Raws li cov qauv thoob ntiaj teb, cov ntsuas ntsuas qhov hnyav yog grams (g), kilograms (kg), thiab lwm yam. Hauv kev tsim cov ntaub tsis-woven, feem ntau siv chav ntsuas qhov hnyav yog grams, thiab grams yog siv los xam cov thickness. grams xa mus rau square gram hnyav, uas yog g / m ^ 2. Vim li cas ho tsis siv millimeters? Qhov tseeb, millimeters kuj tau siv, tab sis lawv tsis tshua siv. Qhov no yog txoj cai kev lag luam. Qhov tseeb, qhov hnyav ntawm square gram tuaj yeem sib npaug rau millimeters hauv thickness, raws li qhov hnyav ntawm cov ntaub tsis-woven yog li ntawm 10g / ㎡ txog 320g / ㎡. Feem ntau, cov tuab ntawm cov ntaub tsis-woven yog 0.1 hli, thiab qhov hnyav ib square meter yog 30g, yog li qhov hnyav ntawm 100 meter yob ntawm cov ntaub tsis-woven yog 0.3kg.
Kev xam cheeb tsam
Cov chav nyob ntawm thaj chaw muaj xws li square metres (square meters), square yards, square feet, thiab lwm yam. Nyob rau hauv cov txheej txheem ntau lawm, cov txheej txheem kev suav tshwj xeeb yuav tsum tau siv vim qhov sib txawv ntawm cov ntaub tsis-woven. Qhov feem ntau siv tuab ntawm cov ntaub tsis-woven yog 0.1mm ~ 0.5mm, thiab qhov kev suav ntawm cheeb tsam feem ntau yog raws li qhov hnyav ib square meter (g / ㎡). Piv txwv li, yog tias qhov hnyav ntawm ib square meter ntawm cov ntaub tsis-woven yog 50 grams, ces cov ntaub tsis-woven yog hu ua 50 grams non-woven fabric (tseem hu ua 50g / ㎡ non-woven fabric).
Hardness (xav) / Gloss
Tam sim no, muaj cov cuab yeej thiab cov cuab yeej siv tsawg heev rau kev ntsuas qhov nyuaj ntawm cov ntaub tsis-woven ntawm lub khw, thiab lawv feem ntau raug sim raws li kev xav ntawm tes / gloss.
Covtensile parameter ntawm non-woven fabrics
Non-woven fabrics muaj longitudinal thiab transverse tensile tsis. Yog tias lawv tsis raug kos, nias, fused thiab txau, qhov sib txawv ntawm longitudinal thiab transverse tensile rog tsis tseem ceeb.
Nyob rau hauv lub ntiajteb txawj nqus ntawm lub ntiaj teb, qhov hnyav thiab qhov hnyav yog sib npaug, tab sis cov units ntawm kev ntsuas txawv. Qhov hnyav ntawm cov khoom uas muaj qhov hnyav ntawm 1 kilogram thaum raug rau sab nraud quab yuam ntawm 9.8 Newtons hu ua 1 kilogram hnyav. Feem ntau, pawg loj feem ntau yog siv los ntawm qhov hnyav, implicitly multiplied los ntawm gravitational acceleration. Hauv Suav teb thaum ub, jin thiab liang tau siv los ua qhov hnyav. Phaus, ounces, carats, thiab lwm yam kuj yog siv los ua qhov hnyav.
Cov units uas nquag siv xws li micrograms (ug), milligrams (mg), grams (g), kilograms (kg), tons (t), thiab lwm yam.
Kev ntsuas kev hloov pauv rooj plaub
1. Yuav ua li cas hloov qhov hnyav ntawm daim ntaub los ntawm g/㎡ mus rau g/meter?
Cov khoom ntawm cov tsis-woven advertising ncej yog 50g / ㎡. Yuav tsum muaj pes tsawg grams ntawm raw cov ntaub ntawv los tsim ib tug 100 meter ntev non-woven npuag? Raws li nws yog 50g / ㎡ tsis-woven npuag, qhov hnyav ib 1 square meter yog 50 grams. Los ntawm kev suav no, qhov hnyav ntawm 100 square meter non-woven npuag yog 50 grams * 100 square meters = 5000 grams = 5 kilograms. Yog li ntawd, qhov hnyav ntawm 100 meter ntev non-woven npuag yog 5 kilograms / 100 meters = 50 grams / meter.
2. Yuav ua li cas hloov grams rau cheeb tsam?
Txoj kab uas hla ntawm cov ntaub tsis-woven yog 1.6m, qhov ntev ntawm txhua yob yog li 1500 meters, thiab qhov hnyav ntawm txhua yob yog 125kg. Yuav ua li cas xam qhov hnyav ib square meter? Ua ntej, xam tag nrho cheeb tsam ntawm txhua yob ntawm cov ntaub tsis-woven. Cov cheeb tsam ncig nrog lub cheeb ntawm 1.6 meters yog π * r ², Ntawm lawv, r = 0.8m, π ≈ 3.14, yog li thaj tsam ntawm txhua yob ntawm cov ntaub tsis-woven yog 3.14 * 0.8 ²≈ 2.01 square meters. Txhua yob hnyav 125 kg, yog li qhov hnyav ib square meter yog 125 grams ib square meter ÷ 2.01 square meters ib yob ≈ 62.19 grams ib square meter.
Xaus
Kab lus no qhia txog txoj kev hloov dua siab tshiab ntawm cov tshuab tsis-woven npuag ntsuas, suav nrog kev suav ntawm cheeb tsam, qhov hnyav, qhov ntev, thiab lwm yam. Hauv cov txheej txheem tsim khoom ntawm cov ntaub tsis-woven, cov teeb meem kev ntsuas feem ntau ntsib. Tsuav yog siv txoj kev hloov dua siab tshiab rau kev xam, cov txiaj ntsig tau raug.
