Nonwoven fabrics, raws li cov khoom siv polymer dav siv hauv kev kho mob, huv, kev lag luam, thiab ib puag ncig, muaj kev cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ntseeg siab ntawm cov khoom kawg. Raws li kev lag luam downstream nce xav tau kev ua haujlwm thiab kev nyab xeeb ntawm cov ntaub tsis yog ntaub, tsim kom muaj kev tshawb fawb thiab kev tswj xyuas zoo tau dhau los ua qhov tseem ceeb hauv kev txhim kho kev sib tw ntawm cov tuam txhab. Tsab ntawv xov xwm no tshawb txog cov ntsiab lus tseem ceeb ntawm kev tswj cov ntaub ntawv tsis zoo los ntawm kev pom ntawm cov khoom siv raw, cov txheej txheem tsim khoom, cov qauv ntsuas, thiab kev txhim kho txuas ntxiv.
Raw Material Control: Ua kom zoo ntawm qhov chaw
Qhov zoo ntawm nonwoven fabrics nyob ntawm qhov ruaj khov ntawm cov ntaub ntawv raw. Synthetic fibers xws li polypropylene (PP) thiab polyester (PET) yog thawj raw khoom rau nonwovens. Cov tsis xws li melt index, molecular hnyav tis, thiab impurity cov ntsiab lus yuav tsum nruj me ntsis raws li cov kev cai ntau lawm. Piv txwv li, kev kho mob - qib nonwovens feem ntau xav tau cov khoom siv raw purity thiab biocompatibility, thaum muaj kev pom cov nonwovens tseem ceeb fiber ntau zog thiab uniformity. Kev tshuaj xyuas cov khoom tsim nyog, kev tshuaj xyuas cov ntaub ntawv pov thawj (COA) ua ntej, thiab ua ntej -cov khoom siv raw khoom sampling thiab kuaj (xws li kev ntsuam xyuas cov ntsiab lus melting thiab cov hmoov tshauv) yog cov kauj ruam tseem ceeb los xyuas kom meej cov khoom zoo. Tsis tas li ntawd, kev tswj qhov kub thiab av noo nyob rau hauv qhov chaw khaws khoom raw yog qhov tseem ceeb los tiv thaiv kev ua haujlwm tsis zoo vim kev nqus dej los yog oxidation.
Precise Management of Production Process Parameters
Cov txheej txheem nonwoven fabrics muaj xws li qhib fiber ntau, carding, web tsim, consolidation (kub dov / hydroentanglement / koob punching, thiab lwm yam), thiab ua tiav. Cov kev hloov pauv hauv cov txheej txheem tsis sib xws ntawm txhua theem tuaj yeem cuam tshuam rau lub cev thiab cov tsos ntawm cov khoom kawg. Piv txwv li, qhov sib piv ntawm qhov kub thiab txias hauv cov txheej txheem kub dov ncaj qha cuam tshuam rau qhov smoothness thiab lub zog ntawm cov ntaub nto; Thaum cov dej siab, koob ceev, thiab fiber ntau entanglement nyob rau hauv cov txheej txheem hydroentanglement txiav txim siab cov ntaub softness thiab abrasion kuj. Cov neeg tsim khoom yuav tsum siv cov txheej txheem tswj hwm kev tswj hwm los saib xyuas qhov tseem ceeb (xws li kub, ceev, thiab siab) hauv lub sijhawm tiag tiag thiab suav nrog cov txheej txheem kev tswj hwm tus lej (SPC) txhawm rau txheeb xyuas cov ntaub ntawv sib txawv thiab kho cov txheej txheem kev sib txawv tam sim. Tsis tas li ntawd, kev saib xyuas cov cuab yeej siv (xws li hloov lub voj voog ntawm daim npav tshuab khaub ncaws thiab cov menyuam nto polishing) muaj kev cuam tshuam ncaj qha rau kev txo qhov tsis xws luag (xws li cov xov paj tawg thiab qhov).
Tsim kom muaj tag nrho - Txheej Txheem Kev Tshawb Fawb
Kev soj ntsuam zoo ntawm cov ntaub tsis muaj ntaub yuav tsum muaj ntau yam - txoj kev ntsuas qhov ntev uas npog peb qhov tseem ceeb: lub cev muaj zog, tshuaj lom neeg kev nyab xeeb, thiab cov yam ntxwv ua haujlwm. Kev ntsuas lub cev muaj xws li kev ntsuas xws li grammage (qhov hnyav hauv ib cheeb tsam), tuab, lub zog tensile (ntev / transverse), lub zog tsim kua muag, thiab huab cua permeability, feem ntau ua raws li cov qauv thoob ntiaj teb (xws li ISO 9081 thiab ASTM D5034) lossis kev lag luam specifications. Kev kuaj tshuaj lom neeg kev nyab xeeb, tsom rau kev siv tshwj xeeb xws li cov khoom siv kho mob lossis cov khoom me me, tsom rau kev tshuaj xyuas cov khoom phom sij xws li formaldehyde, pH, hnyav hlau seem, thiab txwv tsis pub azo dyes. Cov kev ntsuam xyuas no yuav tsum ua raws li GB 15979 (Hygienic Standard for Disposable Hygienic Products) lossis EU REACH cov cai. Kev ntsuas kev ua haujlwm (xws li kev pom kev ua haujlwm zoo thiab cov khoom ua kua dej tsis zoo) simulates cov xwm txheej siv tiag tiag thiab siv cov cuab yeej tshwj xeeb (xws li cov khoom siv hluav taws xob thiab cov ntsuas dej siab hydrostatic) txhawm rau txheeb xyuas kev ua raws li cov qauv kev ua haujlwm ntawm cov khoom.
Kev txhim kho txuas ntxiv thiab ua kom muaj kab lis kev cai zoo
Kev tswj kom zoo tsis yog qhov kawg; nws yog cov txheej txheem cyclical uas tau tsav los ntawm cov ntaub ntawv tawm tswv yim los txhim kho cov txheej txheem. Cov tuam txhab lag luam yuav tsum tsim kom muaj qhov zoo tshaj plaws traceability system uas sau cov khoom siv raw, cov khoom siv tsis zoo, thiab cov txiaj ntsig kev xeem rau txhua pawg ntawm cov khoom lag luam, ua kom muaj kev txheeb xyuas sai ntawm cov teeb meem sib txuas thaum muaj qhov tsis sib xws. Nyob rau tib lub sijhawm, kev cob qhia kev paub txog cov neeg ua haujlwm tsis tu ncua (xws li cov txheej txheem kev khiav haujlwm thiab kev txheeb xyuas qhov tsis zoo) yuav tsum tau ua, thiab cov neeg ua haujlwm pem hauv ntej yuav tsum tau txhawb kom koom nrog "kev pom zoo txhim kho kom zoo" cov haujlwm, hloov kev tswj xyuas kom zoo los ntawm kev tshuaj xyuas- taw qhia txog kev tiv thaiv- taw qhia ib qho. Tsis tas li ntawd, kev tswj xyuas kev sib txuas lus nrog cov neeg siv khoom qis (xws li muab cov kev ntsuam xyuas kev daws teeb meem) tuaj yeem ua tau raws li kev xav tau ntawm kev lag luam thiab tsim kom muaj kev sib tw kom zoo.
Xaus
Kev tswj kom zoo rau cov ntaub tsis muaj ntaub yog kev ua haujlwm zoo, yuav tsum muaj kev sib koom tes tag nrho los ntawm qhov chaw mus rau qhov kawg - neeg siv. Los ntawm kev tswj cov khoom raw nruj, kev tswj xyuas cov txheej txheem zoo, kev soj ntsuam kev tshawb fawb thiab kev ntsuam xyuas, thiab kev txhim kho txuas ntxiv, cov tuam txhab tsis tuaj yeem ua kom cov khoom ua raws li cov qauv, tab sis kuj tseem muab cov khoom siv txhim khu kev qha rau cov chaw tseem ceeb xws li kev nyab xeeb kev kho mob thiab kev tiv thaiv ib puag ncig. Nyob rau hauv cov ntsiab lus ntawm siab - txoj kev loj hlob zoo, tsim kom muaj kev txawj ntse thiab cov qauv kev tswj xyuas zoo yuav dhau los ua tib txoj hauv kev rau kev loj hlob ruaj khov rau cov tuam txhab uas tsis yog ntaub.
