Zosungunulira zopanda zosungunuliraKawirikawiri amanena za zomatira zomwe zimagwiritsidwa ntchito popanga zinthu zopanda zosungunulira. Zomatira zotere sizili ndi zosungunulira zachilengedwe ndipo zili ndi ubwino wokhala wosamala zachilengedwe, wopanda poizoni, komanso wokhala ndi mpweya wochepa wa VOC (volatile organic compound). Izi ndi zina mwa mitundu yayikulu ndi makhalidwe a Zomatira zopanda Zosungunulira:
1. Mitundu ikuluikulu
Chomatira Chopanda Zosungunulira cha Polyurethane
● Polyester polyurethane: ili ndi makhalidwe abwino kwambiri komanso kukhazikika kwa mankhwala ndipo imagwiritsidwa ntchito kwambiri popanga zinthu zomangira.
● Polyether polyurethane: yofanana ndi polyester polyurethane, koma imatha kusiyana ndi zinthu zinazake, monga kukana kwa hydrolysis.
● Chosakaniza cha polyurethane chokhala ndi zigawo ziwiri: chili ndi zigawo ziwiri ndipo chiyenera kusakanizidwa muyeso winawake chikagwiritsidwa ntchito popanga mankhwala ndi kulumikiza ndi kuchiritsa.
● Chogwiritsira ntchito polyurethane compounding agent chimodzi: chosavuta kugwiritsa ntchito, sichifunikira kusakaniza, koma chingakhale ndi ntchito yochepa.
Mitundu ina ya Chomatira Chopanda Zosungunulira
Monga epoxy, acrylic, ndi zina zotero, mitundu iyi ya Solvent-free Laminating Adhesive imagwiritsidwanso ntchito m'magawo enaake, koma poyerekeza ndi polyurethane, gawo lawo pamsika lingakhale locheperako.
2. Makhalidwe
● Kuteteza chilengedwe: Chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga zinthu zoteteza chilengedwe ndi kuteteza chilengedwe, sichikhala ndi zinthu zowononga chilengedwe, komanso chimachepetsa kuipitsa chilengedwe komanso kutulutsa mpweya woipa panthawi yopanga zinthu.
● Kumatirira mwamphamvu: Ma Laminating Adhesive ambiri opanda solvent ali ndi kumatirira kwakukulu, zomwe zingatsimikizire kuti pali mgwirizano wolimba pakati pa zipangizo zosiyanasiyana.
● Kukana kutentha: Ma Laminating Adhesive ena opanda solvent ali ndi kukana kutentha kwambiri kapena kotsika, komwe ndi koyenera kugwiritsidwa ntchito pa kutentha kosiyanasiyana.
● Njira zosiyanasiyana zoyeretsera: Njira zoyeretsera za Solvent-free Laminating Adhesive zitha kuphatikizapo thermosetting, ukalamba, ndi zina zotero, kutengera fomula ya chinthucho ndi zofunikira pa ndondomekoyi.
3. Magawo ogwiritsira ntchito
Chomangira Chopanda Zosungunulira Chotsukira Chopanda Zosungunulira chimagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana, kuphatikizapo koma osati zokhazo:
● Zipangizo zopakira: monga zojambulazo za aluminiyamu, filimu yophimbidwa ndi aluminiyamu ndi pulasitiki ya PET yopangidwa ndi pulasitiki, zomwe zimagwiritsidwa ntchito popanga ma CD a chakudya, ma CD a mankhwala, ndi zina zotero.
● Zipangizo zomangira: monga mapanelo a aluminiyamu, mbale zachitsulo chosapanga dzimbiri, mbale zachitsulo zamitundu yosiyanasiyana ndi mbale zina zachitsulo, komanso zipangizo zina zomangira.
● Magawo a mafakitale: monga nthawi zomwe zinthu ziyenera kupangidwa m'mafakitale monga zamagetsi, magalimoto, ndi ndege.
Mwachidule, Chomangira Chopanda Zosungunulira chili ndi mitundu ndi makhalidwe osiyanasiyana ndipo chimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana. Posankha Chomangira Chopanda Zosungunulira, ndikofunikira kuganizira mozama zinthu monga zofunikira pakugwiritsa ntchito, katundu wa zinthu, ndi zofunikira pakupanga.
