Ubunjineli beplastiki zeplastiki ezixhathisa ubushushu bePPA-GF, i-FR ye-breaker kunye ne-bobbins Umfanekiso obonakalayo

Iiplastiki zobunjineli ezixhathisa ubushushu bePPA-GF, FR yebreaker kunye ne-bobbins

Inkcazelo emfutshane:

I-PPA yeplastiki yezinto zomelele kwaye inzima kune-polyamides ezifana nenayiloni6, kunye ne-66, njl. Uvakalelo olusezantsi kumanzi;Ukusebenza ngcono kwe-thermal; Kwaye ukukhasa, ukudinwa kunye nokumelana neekhemikhali kungcono kakhulu.

Iinkcukacha zeMveliso

Iithegi zeMveliso

I-Polyphthalamide (aka. PPA, i-High Performance Polyamide) yi-subset ye-thermoplastic synthetic resins kwi-polyamide (nylon) intsapho echazwe njengaxa i-55% okanye ngaphezulu i-moles ye-carboxylic acid inxalenye yeyunithi ephindaphindiweyo kwi-polymer chain iqulunqwe ngokudibanisa. ye-terephthalic (TPA) kunye ne-isophthalic (IPA) acids. Ukutshintshwa kwe-aliphatic ithatha isigqibo nge-aromatics kwi-polymer backbone kwandisa indawo yokunyibilika, ubushushu beglasi yokutshintsha, ukuxhathisa imichiza kunye nokuqina.

Iintlaka ezisekwe kwi-PPA zibunjwa zibe ziinxalenye zokutshintsha iintsimbi kwizicelo ezifuna ukumelana nobushushu obuphezulu obunje ngezixhobo zikaloliwe wamandla emoto, indawo yokuhlala yeziqhagamshelo zombane ezinobushushu obuphezulu kunye nezinye izinto ezininzi ezisetyenziswayo.

Iqondo lokushisa lokutshintsha kweglasi yePPA liyenyuka njengoko inani le-TPA linyuka. Ukuba ngaphezu kwe-55% ye-asidi inxalenye ye-PPA yenziwe nge-IPA, ngoko i-copolymer i-amorphous. Iipropathi ze-semicrystalline polymers v amorphous polymers zichazwe kwenye indawo ngokweenkcukacha. Ngokufutshane, i-crystalline inceda ukuchasana kweekhemikhali kunye neempawu zomatshini ngaphezu kweqondo lokushisa lokutshintsha kweglasi (kodwa ngaphantsi kwendawo yokunyibilika). Iipholima ze-Amorphous zilungile kwi-warpage kunye nokungafihli.

Iimpawu zePPA

Izinto zePPA zineepropati ezibalaseleyo zokudibanisa, eziqhuba kakuhle kwi-thermal, umbane, i-physical and chemical properties. Ingakumbi phantsi kobushushu obuphezulu bePPA isenokuqina okuphezulu kunye nokomelela okuphezulu, kunye nokuchaneka okugqwesileyo komgangatho kunye nokuzinza.

Indawo yeSicelo esiPhambili sePPA

Okukhethekileyo usebenzisa ibakala le-Automotive water temp control assembly kunye ne-thermostat body part.
