Kodi ubwino wa meltblown nonwoven ndi wotani pamtengo wake?

Chopanda nsalu chosungunukaMtengo wake ndi wocheperako, pomwe magwiridwe antchito ake ndi otsutsa kwambiri ku hydrolysis ndi dzimbiri la asidi ndi alkali, zomwe zimagwiritsidwa ntchito makamaka pakufunika kutentha sizazikulu, chinyezi chimakhala ndi mikhalidwe yayikulu yogwirira ntchito.

Kawirikawiri, kukana kutentha kwa ulusi wa polyester kumakhala pakati pa 130℃ ndi 150℃. Pofuna kuthana ndi vuto la kuchepa kwa felt wamba wobowoledwa ndi singano wa polyester womwe uli ndi kukana kutentha kopitilira 130℃ kwa nthawi yayitali, fyuluta yatsopano yokhala ndi kutentha kogwira ntchito kwa 150℃ ~ 170℃ imapangidwa, kuti tipewe zinyalala zomwe zimachitika pogwiritsa ntchito fyuluta yotenthetsera kwambiri pamikhalidwe ina yogwirira ntchito.

Felt yopangidwa ndi singano imawongolera kulondola kwa kusefera kwa zinthu zosefera za polyester fiber ndikuchepetsa kutsika kwa kuthamanga, ndipo imakhala ndi mphamvu zosefera pamwamba pa zinthu zosefera zophimbidwa. Mu mndandanda wa zosefera zapakati ndi zachizolowezi, polypropylene needled felt imakhala ndi kukana kutentha kotsika, kukana kotsika kuthamanga komanso kusunga mphamvu. Kuphatikiza pa zabwino za fyuluta yanthawi zonse ya felt, kukana kuvala ndikwabwino kwambiri, yokhala ndi chiŵerengero chokwera mtengo ndipo imakhala kuchuluka kwakukulu kwa mitundu ya zosefera za felt.

Acrylic fiber acupuncture fyuluta ankaona kutentha kwa madigiri 140 ~ 160 Celsius, pogwiritsa ntchito ulusi wopangidwa kunja, ndi kukana bwino kwambiri asidi, alkali ndi hydrolysis kutentha fyuluta zinthu.

Ndife akatswiri pakupanga nsalu zopanda nsalu zosungunuka, talandirani kuti tikuthandizeni ~
