Kuyerekeza pakati pa chingwe cha Kevlar ndi chingwe cha nayiloni

Poyerekeza ndi nayiloni (zotengera nayiloni 66, pali mitundu yambiri ya nayiloni), chingwe cha Kevlar chimakhala ndi kusiyana pang'ono pakukana kuvala ndi kukana dzimbiri, ndipo kusiyana kwakukulu kuli pa malo omwe ali ndi kutentha kwambiri komanso kutsika (malo osungunuka). wa nayiloni-66 ndi 246 ~ 263 ℃).Kutentha kosalekeza kwa Kevlar ndikokulirakulira kwambiri, ndipo kumatha kuthamanga pafupipafupi -196 ℃ ~ 204 ℃ kwa nthawi yayitali.

Kuchepa kwa chingwe cha Kevlar ndi 0 pa 560 ° C ndi 150 C .. Mphamvu pa kutentha kwakukulu sikudzawonongeka ndi kusungunuka, koma mphamvu ya nylon ndi yapamwamba kuposa ya nylon ponena za mtengo.Ngati chilengedwe chomwe mumagwiritsa ntchito sichovuta kwambiri, nayiloni imakhala yotsika mtengo poganizira zachuma.Zoonadi, ngati mukukwera kapena kugwiritsa ntchito kutentha kwakukulu ndi malo ozizira, muyenera kusankha Kevlar chingwe.

Ngati zimangogwira ntchito, chingwe cha Kevlar chimadzaza ndi zikhumbo zazikulu, monga mphamvu, kukana kuvala, kukana nyengo ndi kachulukidwe, zomwe zimakhala zapamwamba kuposa za nayiloni.

Komabe, pakugwiritsa ntchito kwenikweni, machitidwe a chingwe cha Kevlar ndi ochepa kwambiri pa chingwe chomalizidwa, pokhapokha ngati ndi chingwe chapadera monga kukwera chingwe chotetezera, kugwira ntchito kwa chingwe cha nayiloni ndi koyenera kale.Ndi chingwe chapadera, ndipo chingwe cha nayiloni chimakhalanso chokhoza kwambiri.

Choncho, kuunika kwathunthu, deta ndi ubwino wa machitidwe a Kevlar chingwe ndizopambana, ndipo kupititsa patsogolo kachitidwe kumakhala kochepa pakugwiritsa ntchito mwanzeru.

Ubwino wa chingwe cha nayiloni uyenera kukhala wokwera mtengo.Pamene chingwe chikhoza kugwiritsidwa ntchito mokwanira, mtengo wa chingwe ndi wotsika kwambiri.
