I-Polyamide Hot Melt Garnules

Ama-polyamide ashisayo-ama-melt granules ayi-amber-enombala, ephezulu{2}}okunamathelayo kwe-thermoplastic esebenza kahle eklanyelwe izindawo zokuhlangana ezidinga kakhulu lapho isivinini, amandla kanye nokuguquguquka kubaluleke ngokulinganayo. I-resin inikezwa njengama-uniform, ama-cylindrical granules aphansi{4}}othuli ancibilika ngokushesha ku-140-160℃kuya ku-low{11}}viscosity fluid (≈ 3 000–{8}} mPa·s @ 160℃). Le viscosity encibilikayo ephansi kakhulu iqinisekisa ukumanzisa okuvelele kwama-substrates anezimbobo, ama-rough noma ahlukile{12}}iphepha,{13}okungalukiwe{13}imidiya elukiweyo, isikhumba, i-ABS, i-PC, i-PA, insimbi ne-aluminium-ngaphandle kwesidingo seziqalisi noma izixhumi zokubopha.

I-adhesive ibhalansiswa ngamabomu ukuze imiswe ngokushesha-: ifinyelela amandla okubamba kumasekhondi angu-5–10 ngemva kokuminyanisa, okuvumela imisebenzi eya phansi njengokunciphisa, ukupakisha noma ukupakisha ukuthi iqale ngokushesha. Nokho isanikeza isikhathi esimaphakathi esivulekile samasekhondi angu-4-12 (okuncike kwi-substrate kanye ne-ambient), inikeze opharetha noma abahlinzeki be-robotic iwindi elanele ukuze baqondanise izingxenye, ukubeka kahle indawo noma ukwenza izinyathelo zomhlangano wesibili ngaphambi kokuba ibhondi ikhiywe ngendlela engenakuhlehliswa. Le nhlanganisela yenza kube mfishane izikhathi zomjikelezo-emigqeni ejikelezayo enesivinini esiphezulu noma ekhombayo kuyilapho inciphisa ukulahlwa okubangelwa isikhumba esingaphambi kwesikhathi{8}.

Uma usupholile, umgogodla we-polyamide uletha ifilimu eqinile, eguquguqukayo ene:

- Amandla aqinile Amakhulu noma alingana no-6 MPa

- Ukuqina kwe-Shore A 92–96

Ibhondi ihlala iqinile ukusuka ku--20℃ukuya ku- +110℃, ngama-spikes amafushane ukuya ku-130℃ngaphandle kokunyakaza noma i-embrittlement. Ibonisa ukumelana okuhle kakhulu:

- Amafutha

- Ama-Plasticizer

- Hlanganisa ama-asidi/ama-alkali

- Ukuchayeka kwe-UV

Lokhu kwenza ama-granules alungele:

1. Imboni yokuhlunga - Ukuzinza kwe-Pleat, ukuphela{{1}kwe-cap kanye ne-seam bonding ku-HEPA, uphethiloli wezimoto nezihlungi zomoya; i-adhesive imelana nokwehluka kwe-pulsed pressure kanye nokuhlolwa kokuguga kukawoyela oshisayo- > 1 000 h @ 95℃.

2. Ukukhiqizwa kwezicathulo -ama-PA ashisayo-ama-granules ancibilikayo ayancibilika abe yi-160–180℃spray noma i-slot-imigqa yejazi ukuze kwembelwe ungqimba oluqinile oluqinile{5} oluvikela ukukhukhumala kozwane, izinto zokubala kanye namabhodi e-insole ngaphansi kwemizuzwana emi-5.
Umthungo oqinile, oguquguqukayo we-polyamide uyasinda 100 000 kuma-flexible kanye nemijikelezo yokugeza engu-40 degree, kodwa uhlala uphefumula futhi awuncibiliki{2}.
Ngoba iphinda{{0}incibilika ngaphezu kuka-120-130℃kuphela , ingcina efanayo imelana nohhavini bangemuva kokubunjwa kanye nokuvuvukala, okuyenza ibe ukukhetha okuthembekile kwezokuphepha, izicathulo ze-athletic zangaphandle ne-premium.

3.{1}}Ukubumba ingcindezi ephansi{1}}kwezingxenye zikagesi/i-elekthronikhi – Ukuhlanganisa ama-PCB assemblies, amajoyinti ekhebula, izinzwa nama-coil windings; umfutho ophansi womjovo (<10 bar) eliminates mechanical stress, while the amber color allows visual inspection and laser marking.

Umkhiqizo uthobela i-RoHS futhi i-REACH, awuqukethe izincibilikisi noma ama-isocyanate, futhi uqinile{1}}ususa ukukhishwa kwe-VOC futhi wenze lula ukuphepha emsebenzini. Ama-Granules angacutshungulwa ku:

-I-piston evamile noma igiya{1}}izincibilikisi zohlobo

- Layisha ngokuzenzakalela amasistimu e-hopper

- Amayunithi amathangi ajikelezayo

Amaphrofayili e-viscosity azinzile kanye nokuzinza okuhle kakhulu kokushisa (Ngaphansi noma okulingana no-2 % we-viscosity drift ngemva kwamahora angu-48 @ 180 degree) kunciphisa ukwakheka kwe-char kanye nokuphelelwa yisikhathi kwemishini. Ngamafuphi, lawa ma-amber polyamide ashisayo-ancibilika ama-melt ahlinzeka onjiniyela bokukhiqiza inkundla yokunamathela eyodwa, eqinile ehlanganisa ukuphulukiswa okusheshayo, ukuthethelela isikhathi esivulekile nokusebenza okuqinile kuzo zonke izihlungi, izicathulo kanye ne-precision electronics.

Amashadi ashisayo: i-polyamide hot melt garnules, i-China polyamide hot melt garnules abakhiqizi, abahlinzeki, imboni
