Imatrasi yaseNtwasahlobo eHot Melt Adhesive

Imodeli ye-Spring Melt encamathelayo ye-T230 yi-polyolefin{1}ibhloko esekwe ngokukodwa eyenzelwe phezulu-isantya sokunyibilika kwe-non{3}}engalukiweyo i-scrims, ipokotho{4}}iipokotho zentwasa hlobo kunye nemigangatho yokuthuthuzela ngaphakathi kwimigca yomandlalo yangoku{5}. Inikezelwa ngendalo -emhlophe, ephantsi{8}}enevumba eliphantsi, i-T230 inyibilika ngokukhawuleza kwi-5-20 kg enyibilikayo kwaye inikezela ngefilimu ecocekileyo, enamanzi{12}}emhlophe enyamalalayo phakathi kweempahla eziphothiweyo ezimnyama okanye eziprintiweyo, egcina ubuhle beepaneli ezikhuselweyo. Ephakathi 2 000 i-cPs viscosity kwi-170℃ivumela ukuchaneka, okungengawo-umsila wesicelo ngokusebenzisa i-spiral spray, nyibilika{18}}kwimfuno okanye kwi-slot{20}}intloko ezifayo ngelixa uthintela ukucwina{21}}kumhlaba obhityileyo we-15-30 we-polyester ukusetyenziswa okanye i-polyester ye-polyester e-polypro. gm⁻² ngaphandle kokuncama amandla ebhondi.

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 phakathi -elukiweyo kunye nogwebu nasemva 80 000 komjikelo oguquguqukayo (ASTM F1566), ngelixa umsantsa{4}}ubuchule bokuzalisa buvumela i-1-3 mm yokuphakama kwefiber pads kunye ne-spring{7}}iyunithi{8}}elukiweyo. Umdibaniso uhlala unwebeka ukusuka kwi-20℃ukuya +85 isidanga, ukuphumelela imozulu{12}}kuvavanyo lwegumbi kwi-70℃/95% RH nge-168 h ngaphandle kokuphazamiseka okanye ukuphuma kwevumba, ngoko ke oomatrasi bagcina ingqibelelo yabo ngexesha lokupakishwa kwevacuum, ukuthunyelwa kwesikhongozeli kunye nokusetyenziswa kwegumbi elide{16}.

Uxanduva lokusingqongileyo lwakhiwe kwigram nganye ye-T230: ulwakhiwo yi-100 % izinto eziqinileyo, zero-i-solvent, i-halogen{3}isimahla kwaye ihlangabezana ne-REACH, i-RoHS engathanga ngqo{4}}iimfuno zoqhagamshelwano, igcina indawo yokusebenza i-VOC ekhutshwayo ngaphantsi kwe-100 ug m⁻³. Iibhloko zisongelwe ngokwazo kwifilimu esezantsi{7}enyibilika ye-EVA enyibilika ngokuthe ngqo kwitanki eshushu{8}}enyibilikayo, isusa ukupakishwa kwezinto ezilahliweyo kwaye icuthe ukuba sesichengeni somsebenzisi. Ukucoceka kobuchule kuthetha ukwakhiwa kwe-char okumbalwa, ixesha eliphantsi lokucocwa komlomo kunye nokuya kuthi ga kwi-30% yokusetyenziswa okuncamathelayo okusezantsi xa kuthelekiswa neemveliso zesiqhelo ze-EVA, ukunceda abavelisi boomatrasi bafezekise ugcino lweendleko kunye nozinzo ekujoliswe kuko ngaphandle kokubeka esichengeni ukomelela, ibhondi ethe cwaka abathengi banamhlanje abayilindeleyo kumatrasi eprimiyamu yasentwasahlobo.

Iifayile ezishisayo: i-spring umatrasi eshushu inyibilika inncamatheliso, umatrasi waseTshayina oshushu nyibilika abavelisi, ababoneleli, umzi-mveliso
