Taw qhia rau ntau yam khoom ntawm PP non-woven npuag
(1) Lub cev muaj zog: PP non-woven npuag yog ib qho tsis muaj tshuaj lom, tsis muaj kuab lom dawb siab crystalline polymer, uas yog ib qho ntawm ntau yam sib zog ntawm tag nrho cov yas tam sim no.Nws yog qhov tshwj xeeb ruaj khov rau dej, thiab nws cov dej nqus dej hauv dej tsuas yog 0.01% tom qab 14h.Qhov hnyav molecular yog li 80,000 ~ 150,000, nrog zoo formability.Txawm li cas los xij, vim qhov loj me me, cov khoom siv phab ntsa qub yog qhov yooj yim rau sag, thiab cov khoom saum npoo yog ci iab thiab yooj yim rau xim.
(2) Cov khoom siv tshuab: PP non-woven npuag muaj crystallinity siab thiab cov qauv tsis tu ncua, yog li nws muaj cov khoom siv zoo heev.Nws lub zog, hardness thiab elasticity yog siab dua li ntawm high-density PE (HDPE).Qhov zoo tshaj plaws feature yog dabtsi yog khoov qaug zog tsis kam (7 × 10 ^ 7) Qhov thib ob qhib thiab kaw yog khoov yam tsis muaj kev puas tsuaj, thiab kev sib txhuam coefficient qhuav zoo ib yam li nylon, tab sis nws tsis zoo rau nylon hauv qab roj lubrication.
(3) Kev ua haujlwm kub: PP non-woven npuag muaj cov cua sov zoo, cov ntsiab lus melting yog 164 ~ 170 ℃, thiab cov khoom tuaj yeem ua kom tsis muaj menyuam ntawm qhov kub siab tshaj 100 ℃.Nyob rau hauv qhov kev txiav txim ntawm tsis muaj sab nraud quab yuam, nws yuav tsis deform ntawm 150 ℃.Qhov kub ntawm embrittlement yog - 35 ℃, uas yuav tshwm sim hauv qab - 35 ℃, thiab cov cua sov kuj tsis zoo li PE.
(4) Chemical stability: PP non-woven npuag muaj tshuaj stability zoo.Ntxiv rau qhov raug eroded los ntawm acid, nws kuj ruaj khov rau lwm cov tshuaj reagents.Txawm li cas los xij, tsis tshua muaj molecular hnyav aliphatic hydrocarbons, aromatic hydrocarbons, thiab lwm yam tuaj yeem muag thiab o PP non-woven npuag, thiab cov tshuaj stability kuj tseem txhim kho nrog qhov nce ntawm crystallinity.Yog li ntawd, PP non-woven npuag yog tsim rau kev ua cov kav dej hauv Lavxias thiab Suav tshuaj thiab cov khoom siv, nrog cov nyhuv zoo los tiv thaiv corrosion.
(5) Kev ua haujlwm hluav taws xob: Kev ua haujlwm siab ntawm cov ntaub ntawv tsis-woven yog qhov zoo heev.Vim tias nws yuav luag tsis nqus dej, kev ua haujlwm rwb thaiv tsev tsis cuam tshuam los ntawm cov av noo.Nws muaj lub siab dielectric coefficient.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 yog qhov siab heev, thiab nws tsim nyog rau cov khoom siv hluav taws xob.Zoo voltage kuj thiab arc tsis kam, tab sis siab static hluav taws xob, yooj yim rau kev laus thaum tiv nrog tooj liab.
(6) Kev tiv thaiv huab cua: cov ntaub tsis-woven yog cov rhiab heev rau lub teeb ultraviolet, thiab kev laus kuj tuaj yeem txhim kho los ntawm kev ntxiv zinc oxide thiopropionic acid lauryl ester, carbon dub zoo li milky dawb muab tub lim, thiab lwm yam.
