Zomatira za Polyamide

Polyamide adhesive ndiye ukadaulo wofunikira kwambiri kumbuyo kwa TH-9150 ndi TH-9180, mitundu iwiri yotentha kwambiri-yotentha kwambiri-yopangidwira kuti ikhale yovuta kwambiri pamagalimoto ndi zida zamagetsi. TH-9150 imafewetsa pa digiri ya 150, pomwe TH-9180 imakulitsa mphamvu yotentha mpaka 180 digiri; masukulu onsewa amaperekedwa ngati ma pellets akuda omwe amasungunuka mwachangu kumadzimadzi otsika kwambiri, komabe amakhala ndi mphamvu zobiriwira nthawi yomweyo kuti azigwira mwachangu komanso nthawi yayifupi yozungulira. Ma resins ndi 100 % zolimba, RoHS/REACH amatsatira ndipo satulutsa ma VOCs, zomwe zimapatsa opanga njira yoyera, yabwino kwa ogwira ntchito m'malo osungunulira kapena ochitapo kanthu.

M'galimoto, gulu lomatira la polyamide limapanga zomangira, zonjenjemera-zonyezimira pakati pa magawo osiyanasiyana omwe amagwiritsidwa ntchito pama dashboard, makadi a zitseko, zomangira mitu ndi zipolopolo. Imanyowa ndikumangirira ku PP, ABS, PC, PA, SMC, aluminiyamu popanda pretreatment kwambiri, kukhalabe elasticity kuchokera -40 digiri patali pamwamba pa kanyumba kutentha. TH-9180 makamaka yatchulidwa pa injini-zogwiritsa ntchito m'zipinda{7}}mpweya{8}}zoyeretsera nyumba, zovundikira magetsi, mabulaketi a sensa-pomwe kuwoneka kwanthawi yayitali ku mpweya wa 150 degrees, ATF, mafuta agalimoto ndi mchere wamsewu zimatha kuwononga ma olefinic kapena EVA otentha kusungunuka. Msana wake wa hydrophobic umakana kutengeka kwa chinyezi, kotero mphamvu zomangira ndi kukhazikika kwake sizisintha pambuyo pa mayeso a kumizidwa a 1000 h SAE J2196.

Pamwamba pa galimoto, chemistry yomatira ya polyamide imagwiranso ntchito ngati yochepera-pamene imapangidwa ndi makina osindikizira. Ikatenthedwa kufika madigiri 180–220 ndi kubayidwa pa 3–15 bar, TH{8}}9150 ndi TH{16}}9180 imayenda pang’onopang’ono mozungulira ma PCB osalimba, ma solder joints, zolumikizira ndi zomveka{17}}zomveka bwino, zolimba m’masekondi pang’ono kuti apange chipolopolo cha IP68{18}. Chotsatira chake chimapereka mphamvu ya dielectric ya 20 kV mm⁻¹, -40 digiri mpaka 150 digiri ya kutentha kwa njinga, ndi 30 % elongation yomwe imatenga kugwedezeka kwa makina popanda kusweka. Chifukwa chake opanga zingwe amazitenga ngati choloweza chimodzi choloweza m'malo mwa masitepe angapo a epoxy potting kapena kuumba mopitilira muyeso, kuchepetsa ndalama zogwirira ntchito ndikuthamangitsa ntchito.

Magiredi onsewa amaperekedwa m'chinyezi{{0}chosakwanira, matumba okwana 25kg omwe amatha kuperekedwa mwachindunji ku matanki otentha kwambiri-osungunuka kapena otsika{3}}makina opangira mphamvu. Kusungirako pa kutentha kotentha kumapangitsa kuti zinthu ziziyenda bwino kwa zaka zosachepera ziwiri, ndipo zimachotsa kuzizira{{5}kuwononga ndalama zambiri. Kaya ntchitoyo ndi yomangirira zing'wenyeng'wenye zakunja mu shopu ya penti kapena mabatire osindikiza{7}}kuwongolera zamagetsi mkati mwa mphamvu-pack, TH{11}}9150 ndi TH-9180 polyamide adhesive systems imapereka ma OEM agalimoto ndi zamagetsi okhala ndi njira yobiriwira, yowonda komanso yodalirika kwanthawi yayitali.
