Breathable saj zawg zog spunbond pp nonwoven ntaub

Cov yam ntxwv ntawm spunbond pp nonwoven ntaub

1. PP spunbond non-woven npuag muaj cov yam ntxwv ntawm dej tsis kam, breathability, yooj, tsis combustible, tsis muaj tshuaj lom thiab tsis khaus, thiab nplua nuj xim. Yog tias cov khoom raug muab tso rau sab nraum zoov thiab ib txwm decomposed, nws qhov siab tshaj plaws lifespan tsuas yog 90 hnub. Yog hais tias nws muab tso rau hauv tsev thiab decomposed nyob rau hauv 5 xyoos, nws yog non-toxic, tsw, thiab tsis muaj residual tshuaj thaum hlawv, yog li tsis ua phem rau ib puag ncig. Yog li ntawd, kev tiv thaiv ib puag ncig los ntawm qhov no.

2. PP non-woven npuag muaj cov yam ntxwv ntawm cov txheej txheem luv luv, ceev ceev ceev, siab tawm los, tsis tshua muaj nqi, siv dav, thiab ntau yam khoom siv raw.

Kev loj hlob ntawm Spunbond pp nonwoven ntaub

PP tsis-woven npuag kev lag luam hauv Suav teb tau tsim kho sai, ua tiav kev loj hlob sai hauv kev tsim khoom thiab muag khoom, tab sis kuj tseem muaj qee qhov teeb meem thaum lub sijhawm txhim kho. Cov laj thawj rau cov teeb meem xws li tus nqi qis mechanization thiab qeeb industrialization txheej txheem yog multifaceted. Ntxiv rau qhov tseem ceeb xws li kev tswj hwm kev lag luam thiab kev lag luam, kev ua haujlwm tsis muaj zog thiab tsis muaj kev tshawb fawb hauv paus yog qhov teeb meem tseem ceeb. Txawm hais tias qee qhov kev paub ntau lawm tau sau tseg nyob rau xyoo tas los no, nws tseem tsis tau muaj qhov theorized thiab nws nyuaj rau kev coj cov tshuab tsim khoom.

Dab tsi yog cov tshuaj stability ntawm spunbond pp nonwoven ntaub

1. Kev ua tau zoo ntawm lub cev

PP non-woven spunbond npuag yog cov tsis muaj tshuaj lom thiab tsis muaj ntxhiab milky dawb siab crystalline polymer, uas tam sim no yog ib qho ntawm cov khoom siv sib sib zog nqus. Nws yog qhov tshwj xeeb ruaj khov rau dej thiab muaj qhov nqus dej tsuas yog 0.01% tom qab 14 teev hauv dej. Qhov hnyav molecular yog li ntawm 80000 txog 150000, nrog rau kev tsim tau zoo. Txawm li cas los xij, vim yog qhov siab shrinkage tus nqi, cov khoom siv phab ntsa qub yog qhov yooj yim rau indentation, thiab xim ntawm cov khoom yog qhov zoo, ua rau lawv yooj yim rau xim.

2. Mechanical zog

Spunbond pp nonwoven npuag muaj kev huv huv, cov qauv tsis tu ncua, thiab yog li ntawd muaj cov khoom siv zoo heev. Nws lub zog, hardness, thiab elasticity yog siab dua li high-density PE. Cov yam ntxwv tseem ceeb yog muaj zog tiv thaiv kev qaug zog, nrog kev sib txhuam coefficient zoo ib yam li nylon, tab sis tsis zoo li nylon hauv qab roj lubrication.

3. Kev ua haujlwm kub

Spunbond pp nonwoven npuag muaj cov cua sov zoo, nrog lub melting point ntawm 164-170 ℃. Cov khoom tuaj yeem tua kab mob thiab ua kom tsis muaj menyuam ntawm qhov kub siab tshaj 100 ℃. Nyob rau hauv tsis muaj sab nraud quab yuam, nws tsis deform txawm nyob rau ntawm 150 ℃. Lub embrittlement kub yog -35 ℃, thiab embrittlement tshwm sim hauv qab -35 ℃, nrog qis kub tsis kam tshaj PE.

4. Kev ua haujlwm hluav taws xob

Spunbond pp nonwoven npuag muaj kev ua haujlwm zoo heev ntawm kev rwb thaiv tsev. Vim nws yuav luag tsis muaj dej nqus, nws qhov kev ua haujlwm rwb thaiv tsev tsis cuam tshuam los ntawm cov av noo, thiab nws muaj dielectric coefficient siab. Nrog rau qhov nce ntawm qhov kub thiab txias, nws tuaj yeem siv los ua cov khoom siv hluav taws xob rwb thaiv tsev. Lub zog tawg kuj tseem siab heev, ua rau nws tsim nyog rau cov khoom siv hluav taws xob, thiab lwm yam zoo voltage kuj thiab arc tsis kam, tab sis muaj hluav taws xob zoo li qub thiab kev laus yooj yim thaum sib cuag nrog tooj liab.

5. Huab cua tsis kam

Spunbond pp nonwoven ntaub yog rhiab heev rau ultraviolet rays. Ntxiv zinc oxide thiopropionate lauric acid ester thiab carbon dub zoo li mis nyuj dawb tuaj yeem txhim kho nws txoj kev laus.
