Kodi kukhazikika kwa mankhwala a spunbond pp nonwoven nsalu ndi chiyani

1. Kuchita kwathupi

Nsalu ya PP yosawomba spunbond ndi polima yopanda poizoni komanso yopanda fungo yamkaka yoyera kwambiri, yomwe pakadali pano ndi imodzi mwamitundu yopepuka kwambiri yamapulasitiki. Imakhala yokhazikika pamadzi ndipo imakhala ndi kuchuluka kwa madzi kwa 0.01% pambuyo pa maola 14 m'madzi. Kulemera kwa maselo kumachokera ku 80000 mpaka 150000, ndi mawonekedwe abwino. Komabe, chifukwa cha kuchuluka kwa shrinkage, zida zoyambirira zapakhoma zimakhala zosavuta kulowa mkati, ndipo mtundu wamtundu wa zinthuzo ndi wabwino, zomwe zimapangitsa kuti zikhale zosavuta kuzikongoletsa.

2. Makina katundu

Nsalu ya Spunbond pp nonwoven imakhala ndi ukhondo wambiri, kapangidwe kake nthawi zonse, chifukwa chake imakhala ndi makina abwino kwambiri. Mphamvu zake, kuuma kwake, ndi kukhazikika kwake ndizokwera kwambiri kuposa PE yapamwamba kwambiri. Chodziwika bwino ndikukana kutopa kopindika, komwe kumakhala kowuma kofanana ndi nayiloni, koma osati bwino ngati nayiloni pansi pamafuta opaka mafuta.

3. Kuchita kwa kutentha

Chogulitsacho chikhoza kupha tizilombo toyambitsa matenda komanso chosawilitsidwa pa kutentha pamwamba pa 100 ℃. Popanda mphamvu yakunja, sichimapunduka ngakhale pa 150 ℃. The embrittlement kutentha ndi -35 ℃, ndi embrittlement amapezeka pansipa -35 ℃, ndi kukana kutentha kutsika kuposa PE.

4. Kuchita kwamagetsi

Nsalu ya Spunbond pp nonwoven imakhala ndi magwiridwe antchito apamwamba kwambiri. Chifukwa chakuti pafupifupi palibe madzi, ntchito yake yotsekemera simakhudzidwa ndi chinyezi, ndipo imakhala ndi dielectric coefficient. Ndi kuwonjezeka kwa kutentha, chitha kugwiritsidwa ntchito kupanga zida zotenthetsera zamagetsi. Kuwonongeka kwamagetsi kumakhalanso kokwera kwambiri, kumapangitsa kuti ikhale yoyenera kwa zipangizo zamagetsi, etc. Good voltage resistance ndi arc resistance, koma magetsi otsika kwambiri komanso kukalamba mosavuta akakumana ndi mkuwa.

5. Kukana kwanyengo

Nsalu ya Spunbond pp nonwoven imakhudzidwa kwambiri ndi kuwala kwa ultraviolet. Kuonjezera zinc oxide thiopropionate lauric acid ester ndi carbon wakuda ngati zoyera zoyera zamkaka zimatha kusintha kukalamba kwake.
