Thermosetting ufa wokutira ndi thermoplastic ufa wokutira
Kuphimba powonjezera ndi mtundu wa zokutira zomwe zimagwiritsidwa ntchito ngati ufa wopanda pake, wowuma. Kusiyanitsa kwakukulu pakati pa utoto wamadzimadzi wamba ndi kupaka ufa ndikuti kupaka ufa sikufuna zosungunulira kuti zisunge zomangira ndi zodzaza mu mawonekedwe a kuyimitsidwa kwamadzi. Chophimbacho chimagwiritsidwa ntchito mothandizidwa ndi electrostatically ndipo chimachiritsidwa pansi pa kutentha kuti chizitha kuyenda ndi kupanga "khungu". Zopangira ndi literally ufa, wosakanizidwa youma, extruded, ndi pansi mu chomaliza zinthu.An chilengedwe otetezeka ❖ kuyanika amene angapereke zosiyanasiyana apamwamba amamaliza kumapangitsa ufa wotchuka njira ina mu nyengo yovuta zachilengedwe zimene tikukhala masiku ano.
Ufa ukhoza kukhala a Thermoplastic kapena polima thermoset. Nthawi zambiri amagwiritsidwa ntchito popanga kumaliza kolimba komwe kumakhala kolimba kuposa utoto wamba. Kupaka ufa kumagwiritsidwa ntchito makamaka popaka zitsulo, monga zida zapakhomo, zotulutsa aluminiyamu, ndi zida zamagalimoto ndi njinga. Ukadaulo waposachedwa umalola kuti zida zina, monga MDF (zapakati-kachulukidwe fiberboard), kuti zikhale ufa pogwiritsa ntchito njira zosiyanasiyana.
Kupaka kwa ufa wa thermoplastic sikuchitapo kanthu pamankhwala. Amagwiritsidwa ntchito pochita ntchito ndipo amagwiritsidwa ntchito m'mafilimu akuluakulu, nthawi zambiri 6-12 mils. Amagwiritsidwa ntchito pazinthu zosiyanasiyana zomwe zimafuna kumaliza mwamphamvu ndi kukana komanso / kapena kukana mankhwala.
Thermosetting ufa wokutira umayikidwa kenako kuchiritsidwa mu uvuni pa kutentha kwina kwa nthawi inayake. Njira yochiritsira idzapangitsa kuti kuphatikizika kwa mankhwala kuchitike, kusintha ufa kukhala filimu yosalekeza yomwe siidzabwereranso.Amagwiritsidwa ntchito pazinthu zosiyanasiyana zogwira ntchito komanso zokongoletsera ndipo nthawi zambiri amagwiritsidwa ntchito m'mafilimu ochepetsetsa, makamaka mu filimu makulidwe a 1.5 mpaka. 4 mil.
