Spring Mattress Hot Melt Adhesive

Spring Mattress Hot Melt Adhesive Model T230 ndi polyolefin-yopangidwa ndi makina opangidwa kuti ikhale yokwera-yothamanga kwambiri-yopanda ma scrims, thumba-mafukufuku ndi masitayilo osangalatsa mkati mwa mizere yamakono ya masika{5}. Zoperekedwa mu {{7}zoyera, zotsika{8}}zonunkhira bwino, T230 imasungunuka mwachangu mu muyezo wa 5–20 kg wosungunuka ndikupereka filimu yaukhondo, yamadzi{12}}yoyera yomwe imasoweka pakati pa zoluka zakuda kapena zosindikizidwa, zomwe zimasunga kukongola kwa mapanelo otchingidwa. Kuwoneka bwino kwake 2 000 cPs viscosity pa 170 digiri kumalola kugwiritsa ntchito moyenera, kosakhala{17}}kupyolera mu spiral spray, melt-pa{19}}zofuna kapena zolowetsa{20}}dieheads popewa kulowetsedwa{21}}pa thinnest 15–30 webs, polyester polyester kapena polyester gm⁻² popanda kupereka mphamvu zomangira.

A sharply defined softening point of 107–117 °C gives T230 an optimal processing window: the adhesive becomes fully fluid at 160–180 °C for fast start-up, yet sets in 3–5 s on cooled calender rolls, enabling line speeds above 60 m min⁻¹ without pop-opens or edge lift. Once solidified, the flexible polyolefin backbone maintains peel values >8 N cm⁻¹ pakati pa-zolukidwa ndi thovu ngakhale zitatha 80 000 zozungulira (ASTM F1566), pomwe kusiyana{4}}kutha kutha kutha kutengera ma fiber pads a 1–3 mm ndi ma spring{7}}unit non{8}}wovens. Mbaliyi imakhala yotanuka kuyambira -20 digiri kufika ku +85 digiri , kupitilira kutentha-kuyesa kwa chipinda pa 70℃/95 % RH kwa 168 h popanda delamination kapena fungo, kotero kuti matiresi azikhalabe olimba panthawi yolongedza vacuum, kutumiza zotengera komanso kugwiritsa ntchito nthawi yayitali{{16} mchipinda chogona.

Udindo wa chilengedwe umapangidwa mu gram iliyonse ya T230: kupanga kwake ndi 100 % zolimba, ziro{{2}zosungunulira, halogen{{3}zaulere ndipo zimakwaniritsa zofunikira za REACH, RoHS mosalunjika-zofuna kulumikizana, kusunga utsi wa VOC pamalo ogwirira ntchito osakwana 100 ug m⁻³. Mabuloko amakulungidwa payekhapayekha-filimu yosungunula ya EVA yomwe imasungunuka mwachindunji-mu tanki yosungunuka, kuchotsa kulongedza zinthu komanso kuchepetsa kukhudzidwa kwa opareshoni. Kugwiritsa ntchito bwino kumatanthawuza kuchulukira kwamoto{10}kuchuluka, kuchepa kwa nthawi yotsuka m'mphuno ndi kumamatira mpaka 30 % kuyerekeza ndi zinthu zamasiku onse za EVA, kuthandiza opanga matiresi kuti achepetse mtengo wake komanso kuti akwaniritse zolinga zake zokhazikika popanda kusokoneza mgwirizano wamphamvu womwe ogula masiku ano amayembekezera kuchokera kumamatiresi apamwamba kwambiri.
