I-Polyamide Hot Melts Yesihlungi Samafutha

I-PA150 iyinhlaka{1}}i-granule, ephezulu-esebenza nge-polyamide eshisayo encibilikayo eyenziwe ngokukhethekile njengenye yezinto ezincibilikayo ezihlala isikhathi eside ze-polyamide zokuhlanganiswa kwesihlungi sikawoyela. Idizayinelwe ukujabulisa-izimbambo eziqinisayo kanye nokungezwani-izintambo ezigxilwa ku-spin-zivuliwe kanye nezihlungi zikawoyela we-cartridge, ihlanganisa ububanzi obuncibilikayo obuncane -nokucutshungulwa kwephunga eliphansi,{7}}okusiza abakhiqizi ukuhlangabezana nezimfuneko ze-REACH kanye ne-ELV ngenkathi ikhipha izincibilikizo esitolo.

I-adhesive ibonisa indandatho kanye{1}}nendawo yokuthambisa yebhola engu-145-155℃kanye ne-viscosity encibilikayo elawulwayo engu-4500 cps ku-170℃. Le viscosity ephakathi-nobubanzi ivumela i-PA150 ukuthi igeleze ngokufanayo phakathi kwemibhobho ye-swirl-spray ukuze izimbambo zibe ukuphakama okungaguquki, nokho ihlala i-thixotropic ngokwanele ukuvimbela ukuntengantenga ekuncengeni okuqondile. Isikhathi esifushane sokuvula (<10 s) means the adhesive solidifies almost immediately after compression, locking pleat geometry and permitting filters to be inverted or transferred without wait, raising takt speed by up to 20 % on rotary machines.

Ukuqina okushisayo namakhemikhali kungamandla abalulekile ahlukanisa i-PA150 kunezinye ze-EVA noma ze-PO. Ukuhlolwa kokucwiliswa okuqhubekayo kuwoyela wokwenziwa we-5W-30 ku-150℃ngombukiso wamahora angu-1000<5 % loss of shear strength, while cyclic exposure to 180 °C under-hood spikes and –40 °C cold-crank cycles causes no cracking or debonding. The polyamide backbone resists gasoline, diesel, biodiesel, brake fluid and glycol-based coolants, ensuring that bonded joints survive the 15 000 km service life typical of passenger-car oil filters without bypass or media collapse.

Ngenxa yokuthi i-PA150 iqinile ngo-100 % futhi i-RoHS{2}}iyahambisana, isekela izitshalo zokuhlunga{3}}ezingcolile; ukwakheka kwe-char kuncane, kunikeza impilo yebhodwe engu-48 h ku-180℃kanye nokunciphisa umlomo wombhobho-ukuhlanza isikhathi sokuphumula. Kungakhathaliseki ukuthi uqinisa-ama-cartridges edizili asindayo noma ama-elementi emidiya-e-spin synthetic{10}}aphakeme{10}}, lokhu kuncibilika okushisayo kwe-polyamide kokukhiqiza isihlungi sikawoyela kuletha ukumelana nowoyela okuthembekile, ukuphulukiswa okusheshayo kanye nenqubo yokuhlanganisa eluhlaza, esebenza kahle kakhulu.

Amashadi ashisayo: i-polyamide encibilikayo eshisayo yesihlungi samafutha, i-polyamide yaseChina iyancibilika yabakhiqizi besihlungi samafutha, abahlinzeki, imboni
