Cas PP nonwoven npuag tiv taus kev laus
Polypropylene tsis-ntaub npuag tseem hu ua PP tsis-ntaub, polypropylene yog ib hom khoom siv raw khoom siv coj los ua cov txheej txheem ntawm cov ntaub tsis-woven, PP non-woven npuag yog feem ntau siv hauv lub neej txhua hnub, xws li le buckle khob, ntau ntau yog PP, polypropylene.
PP non-woven npuag yog hom tshiab ntawm cov qauv fiber khoom nrog mos, breathable thiab tiaj tus qauv, uas muaj cov yam ntxwv ntawm cov txheej txheem luv luv, kev tsim khoom ntau lawm, cov txiaj ntsig kev lag luam tseem ceeb, cov khoom lag luam nplua nuj thiab ntau daim ntawv thov ntau.
Cov khoom siv raw siv rau PP nonwoven npuag yog PP fiber, uas yog qhov ntau tshaj plaws ntawm cov tshuaj fiber ntau hauv cov khoom siv ntawm nonwoven.
Piv nrog rau lwm cov fibers, PP fiber ntau qhov sib piv hauv qhov sib piv, muaj zog ntau dua, zoo dua hauv hnav tsis kam, zoo dua hauv elasticity rov qab, zoo dua hauv pob tsis kam, zoo dua hauv cov kua qaub thiab alkali tsis kam, zoo dua hauv tshuaj lom neeg corrosion dua li lwm cov fibers, zoo dua hauv microbial tsis kam, tsis muaj pwm thiab tsis muaj npauj.
PP cov khoom siv tsis-woven tau siv dav hauv kev lim, kev kho mob, kev tu huv, kev kho mob, kev lag luam, kev ua liaj ua teb, kev txuag dej hauv pej xeem, kev tsim kho, kho kom zoo nkauj hauv tsev thiab lub neej hauv ntau daim teb.
Polypropylene yog cov khoom siv feem ntau siv thiab cov khoom siv tseem ceeb polymer fiber ntau. Ze li ntawm 94% ntawm spunbonded thiab mown-blown daim ntaub raw cov ntaub ntawv raw khoom hauv Suav teb yog polypropylene.
Hauv thaj teb ntawm kev kho mob kev kho mob, kev huv huv thiab kev noj qab haus huv, daim ntawv thov ntawm polypropylene nonwovens suav rau 50% ntawm tag nrho cov tsis yog.
Polypropylene fiber muaj qhov ntom tsawg heev (0.91g / cm3);
Cov ntsiab lus dej tsawg (<>
Tshuaj lom neeg tsis zoo (acid, alkali, kuab tshuaj);
Anti-mildew, anticorrosive, mothproof, antibacterial;
Kev rwb thaiv tsev zoo, kev tiv thaiv kub, rwb thaiv tsev ua tau zoo;
Siab txhav, lub zog tensile zoo (4.5 ~ 7.5cN / dtex);
Nkees zoo thiab hnav tsis kam;
Kub ua hauj yog kub 120 ℃ thiab lub ntsiab lus melting yog 165 ℃.
Yooj yim rov siv dua thiab lwm yam khoom.
Cov yam ntxwv no ua rau polypropylene fiber thiab lwm cov khoom siv hluavtaws muaj ob qhov sib txawv loj: thawj yog tias nws hygroscopicity tsawg heev, uas ua rau polypropylene fiber muaj cov pa phem zoo tshaj thiab yuav luag zoo tib yam qhuav thiab ntub lub xeev cov yam ntxwv;
Thib ob, nws muaj qhov ntom ntom qis tshaj plaws ntawm txhua cov fibers, uas muab nws cov kev pov hwm zoo rau tib qhov nyhav.
Vim tias cov thermal conductivity ntawm polypropylene qis tshaj plaws ntawm txhua tus fibers, nws cov nyhuv rwb thaiv tsev zoo dua li cov ntaub plaub, thiab nws cov fiber ntau qhov qis dua, tab sis kuj muaj thaj tsam loj dua, tuaj yeem siv ua cov khoom hauv tsev thiab tsheb sab hauv, cov rwb thaiv tsev thermal. thiab suab-haum, rwb thaiv tsev kub cov ntaub ntawv.
Ntawm qhov tod tes, polypropylene tsis hnov mob nrog cov tshuaj lom neeg cov tshuaj lom neeg thiab muaj cov tshuaj tiv thaiv muaj zog. Polypropylene nonwovens tuaj yeem siv los ua cov khoom lag luam geotextiles, txhuas roj teeb diaphragm, cov khoom siv lim, thiab lwm yam.
Vim tias tsis muaj cov pab pawg nquag nyob hauv cov saw tseem ceeb ntawm polypropylene zoo dener fiber, cov khoom nws tus kheej tsis yooj yim kom yoov los ntawm cov kab mob thiab pwm, thiab kev sib cuag nrog tib neeg daim tawv nqaij tsis muaj voos thiab lom, uas muaj kev ua haujlwm huv huv, yog li ntawd, nws tuaj yeem siv dav hauv kev kho mob thiab kev kho mob.
Tsis tas li ntawd, lipophilic saw cov qauv ntawm polypropylene thiab cov txheej txheem sab hauv capillary tsim los ntawm cov qauv siv hluav taws xob hloov thaum lub fiber ntau tom qab ua rau cov roj muaj zog nqus cov khoom lag luam polypropylene thiab kev tsim cov roj-nqus cov ntaub ntawv xav.
