SMS tsis-ntaub npuag siv polypropylene PP (nrog rau ntuj bacteriostasis thiab hydrophobicity) raws li cov khoom siv tseem ceeb, thiab cov kab uas hla fiber tuaj yeem ncav cuag 0.5-10 microns. Cov ultra-fine fibers nrog cov qauv tshwj xeeb capillary nce tus naj npawb thiab thaj chaw ntawm cov fibers ib cheeb tsam, yog li cov ntaub yaj cua tshuab tau cua pom zoo thiab yog cov ntaub npog qhov ncauj zoo.
Tam sim no, cov txheej txheem tseem ceeb rau kev tsim cov khoom lag luam SMS (SMS non-woven fabrics) suav nrog "ib qib", "ob kauj ruam" thiab "ib thiab ib nrab kauj ruam".
Cov txheej txheem ib kauj ruam yog qhov tshwj xeeb los ntawm kev siv cov khoom nyoos hlais thiab siv cov spunbonded thiab yaj cov txheej txheem tshuab kom yaj cov khoom nyoos ncaj qha thiab tig lawv mus rau hauv cov nets. Tsuav yog cov phiaj xwm txheej txheem txheej txheem ntawm cov txheej txheem sib txawv tsim nyog, cov khoom tuaj yeem muaj cov qauv sib txawv. Tom qab laminating thiab sib xyaw txhua txheej ntawm cov nets fiber ntau, lawv feem ntau suav nrog ua cov ntaub los ntawm cov tshuab kub dov "Cov yam ntxwv ntawm" txheej txheem ib kauj ruam "yog tias cov yaj yog ncaj ncaj spun rau hauv net, lub xeev ntawm txhua qhov kev sib tw tuaj yeem hloov kho ntawm nws tus kheej, cov txheej txheem tsim khoom tuaj yeem tswj tau, cov xwm txheej huv huv yog qhov zoo, kev ua haujlwm tau nrawm, qhov feem ntawm txhua txheej ntawm cov xov paj fiber tuaj yeem hloov kho raws li xav tau, thiab SMS khoom ntawm ntau yam tshwj xeeb tuaj yeem tsim tawm. Nws yog txheej txheem tseem ceeb niaj hnub no.
Cov txheej txheem ob kauj ruam: thaum cov khoom lag luam SMS tau tsim los ntawm ob kauj ruam txheej txheem, ua tiav cov ntaub spunbonded thiab cov ntaub yaj cua uas tsis tau tawg nyob rau hauv qee qhov kev txiav txim, laminated nyob rau hauv kev txiav txim, thiab tom qab ntawd sib sau ua ke los ntawm cov kub zeb zeb los tsim cov khoom lag luam SMS "Ob-kauj ruam txoj kev yog tus yam ntxwv ntawm cov cuab yeej yooj yim thiab tus nqi qis. Qhov tseeb, txheej txheem "ob kauj ruam" yog siv cov tshuab laminated sib xyaw ua ke. Nws tseem tuaj yeem sib xyaw lwm cov ntaub ntawv, siv lwm cov ntaub ntawv sib txawv, thiab sib sau ua ke peb txheej txheej ua ke los ntawm cov txheej txheem sib txawv, xws li ultrasonic thiab kub yaj nplaum.
Ib kauj ruam thiab ib nrab txoj hauv kev: hauv ob txoj hauv kev txheej txheem, cov txheej txheej tshuab cua tshuab ua kom qhuav nyob rau ntawm qhov chaw kuj tseem tuaj yeem hloov cov khoom cua tshuab cua tshuab, yog li kom tau txais qhov thiaj li hu ua "ib kauj ruam thiab ib nrab txoj kev" txheej txheem sib xyaw. . Cov ntaub spunbonded tau siv ua txheej txheej hauv qab thiab txheej txheej los ntawm ob qho khoom siv tsis sib xws. Cov cua tshuab cua tshuab yaj ntawm cov txheej nruab nrab yog ncaj ncaj mus rau hauv lub tshuab los ntawm cov tshuab cua tshuab, tso rau saum npoo ntawm cov ntaub spunbonded ntawm txheej hauv qab, thiab tom qab ntawd npog nrog cov ntaub spunbonded ntawm txheej txheej sab saud. Nws yog qhov zoo tshaj plaws los siv lub tshuab kub kub los tsim cov khoom lag luam SMS.
