Polyamide Hot Melt Garnules

I-Polyamide eshushu -i-granules enyibilikayo yi-amber-enemibala, ephezulu{2}}i-thermoplastic encamathelayo esebenza kakuhle eyinjineli yokudityaniswa kwemeko-bume apho isantya, amandla kunye nokuguquguquka kubalulekile ngokulinganayo. I-resin inikezelwa njenge-uniform, i-low -ephantsi kweegranules ze-cylindrical ezinyibilika ngokukhawuleza kwi-140-i-160℃ukuya kwi-low{11}}viscosity fluid (≈ 3 000-{8}} mPa · s @ 160 degree). Le viscosity ephantsi kakhulu yokunyibilika iqinisekisa ukumanzisa okugqwesileyo kwe-porous, rough or dissimilar substrates{12}}nephepha, non{13}nolwazi olulukiweyo, ithwathwa, ABS, PC, PA, intsimbi kunye nealuminiyam-ngaphandle kwesidingo seprimers okanye iziqhoboshi zoomatshini.

I-adhesive ilungelelaniswa ngenjongo yokuseta ngokukhawuleza{0}}phezulu: ifikelela kumandla okuphatha kwi-5-10 imizuzwana emva koxinzelelo, ivumela imisebenzi esezantsi efana nokucheba, ukupakisha okanye ukupakisha ukuba iqalise ngokukhawuleza. Nangona kunjalo inika ixesha eliphakathi elivulekileyo le-4-12 imizuzwana (i-substrate kunye ne-ambient dependent), inika abaqhubi okanye ii-robotic dispensers iifestile ezaneleyo zokulungelelanisa iindawo, ukubeka indawo echanekileyo okanye ukwenza amanyathelo endibano yesibini phambi kokuba ibhondi itshixe ngokungenakujikwa. Le ndibaniselwano yenza mfutshane amaxesha omjikelo kwi{7}}isantya esiphezulu sokujikeleza okanye imigca yesalathiso ngelixa ucutha ukwala okubangelwa lulusu oluphambi kwexesha{8} ngaphezulu.

Nje ukuba ipholile, umqolo we-polyamide uhambisa ifilimu eqinile, ebhetyebhetye ene:

- Amandla okuqina Makhulu okanye alingana no-6 MPa

- Unxweme A ubulukhuni 92–96

Ibhondi ihlala yomelele ukusuka kwi -20℃ukuya kwi +110℃, kunye ne spikes ezimfutshane ukuya kwi 130℃ngaphandle kokugrumba okanye imbrittlement. Ibonisa ukumelana okugqwesileyo koku:

- Ioyile

- IiPlastiki

- Dilulula iiasidi/iialkali

- Ukuba sesichengeni kwe-UV

Oku kwenza ukuba iigranuli zilungele:

1. Umzi-mveliso wokuhluza-Uzinzo lwePleat, ukuphela-kwe-cap kunye ne-seam bonding kwi-HEPA, amafutha emoto kunye nezihluzi zomoya; i-adhesive imelana ne-pulsed pressure differentials kunye neshushu-uvavanyo lokuguga kweoyile > 1 000 h @ 95 degree.

2. Ukwenziwa kwezihlangu -PA kushushu{1}}iigranuli ezinyibilikayo zinyibilika zibe 160–180 isitshizi seedigri okanye i-slot{4}}imigca yebhatyi ukubeka umaleko obhityileyo, ophezulu{5}}oluqilima olugcina inzwane, izinto zokubala kunye neebhodi ze-insole phantsi kwe-5 s.
Umthungo oqinileyo, obhetyebhetye we-polyamide uyasinda 100 000 kwiziguquko kunye ne-40℃degree yokuhlamba, kodwa uhlala uphefumla kwaye unyibiliki{2}isimahla.
Kuba iphinda -inyibilika ngaphezulu kwe-120-i-130 isidanga, into encamathelayo efanayo imelana nee-oveni zasemva kokubunjwa kunye nokuvuthuluka, oko kuyenza ibe lolona khetho luthembekileyo lokhuseleko, izihlangu zangaphandle kunye ne-premium yezemidlalo.

4 Uxinzelelo lwenaliti ephantsi (<10 bar) eliminates mechanical stress, while the amber color allows visual inspection and laser marking.

Imveliso yi-RoHS kwaye i-REACH iyahambelana, ayinazinyibilikisi okanye ii-isocyanates, kwaye iqinile nge-100% -iphelisa ukukhutshwa kwe-VOC kwaye yenza lula ukhuseleko emsebenzini. Iigranules zinokulungiswa nge:

- ipiston eqhelekileyo okanye izixhobo{1}}zohlobo lwezinyibilikisi

- Izixokelelwano zehopper ezizenzekelayo

- Iiyunithi zetanki ezijikelezayo

Iiprofayili ze-viscosity ezizinzileyo kunye nokuzinza okuhle kakhulu kwe-thermal (Ngaphantsi okanye ilingana ne-2% ye-viscosity drift emva kwe-48 h @ 180 degree) ukunciphisa ukubunjwa kwe-char kunye nexesha lokunciphisa izixhobo. Ngamafutshane, ezi granule ze-amber polyamide zishushu{4}zinyibilika zibonelela iinjineli zemveliso ngeqonga elinye elincamathelayo elidibanisa ukuphilisa ngokukhawuleza, ukuxolela ixesha elivulekileyo kunye nokusebenza okuzinzileyo kuzo zonke izihluzi, izihlangu kunye ne-elektroniki echanekileyo.

Iifayile ezishisayo: i-polyamide eshushu inyibilika iigarnules, iTshayina i-polyamide eshushu yinyibilikisa abavelisi beegarnules, ababoneleli, umzi-mveliso
