ʻO nā hiʻohiʻona a me nā noi nui o ka Nylon PPA kiʻekiʻe

Nā hiʻohiʻona hana PPA

1, PPA he mea pale wela kiʻekiʻe, me ka helu heheʻe ma waena o 310-325°C a me kahi wela wela (HDT) ma waena o 280-290°C.

2, PPA maikaʻi loa ka aila kūpaʻa a me ke kūpaʻa maikaʻi loa i nā aila like ʻole e like me ka aila wahie a me ka aila lubricating, ʻoiai ma kahi wela kiʻekiʻe o 150 ℃

3, PPA loaʻa i ke kūpaʻa dimensional maikaʻi loa a me ka warpage haʻahaʻa

4, ʻOi aku ka haʻahaʻa o ka wai o ka PPA ma mua o ka PA6 a i ʻole PA66, a hiki i kona ikaika tensile ke noho ma luna o 80% ʻoiai ma hope o ka hoʻokomo ʻia ʻana i ka wai anuanu no kekahi mau makahiki.

5, PPA maikaʻi loa ka pale ʻana i ka wā a he kūpono hoʻi no ka hoʻohana ʻana i waho no ka wā lōʻihi ma lalo o nā kūlana ʻino e like me ka radiation UV kiʻekiʻe, ka haʻahaʻa kiʻekiʻe, a me ka wela kiʻekiʻe.

6, He hana maikaʻi loa ka PPA a hiki i ka pae US FDA

Nā wahi noi PPA

ʻoihana kaʻa:nā ʻāpana hana, nā hale thermostat, nā pauma mana, nā ʻāpana paʻa, nā ʻaila ʻaila, etc.

Nā kahua uila a me ka uila:nā mea hoʻohui, nā mea hoʻohui SMT, nā mea hoʻokaʻawale kaapuni, nā kau kāleka, etc.

ʻOihana mīkini:nā pāpaʻi wai, nā mea ʻaila pauma, nā impellers, nā paipu wai wela, nā bearings, gears, etc.

Nā mea e pono ai i kēlā me kēia lā:nā pāpaʻi wai, nā mea ʻaila pauma, nā impellers, nā paipu wai wela, nā bearings, gears, etc.

ʻoihana kaʻa

Loaʻa nā waiwai PPA i hoʻoikaika nui ʻia no nā kaʻa. I mea e hoʻokō ai i nā koi hoʻohana o nā ʻāpana automotive, ua hoʻoikaika ʻia nā mea PPA i kēia mau waiwai:

Kiʻekiʻe ikaika, kiʻekiʻe rigidity

ʻOi aku ka maikaʻi o ka creep resistance, ka ikaika luhi a me ke kūpaʻa vibration

ʻOi loa ka paʻa ʻana

Ke kū'ē kemika i nā wahie kaʻa, nā wai a me nā aila

ʻO ke kū'ē wela kiʻekiʻe, ke kūpaʻa hoʻoheheʻe ultrasonic;

ʻO ka machinability maikaʻi me ka paʻa ʻana o ka mold tolerances.

uila a me ka uila

Loaʻa nā waiwai PPA kiʻekiʻe no ka uila a me nā noi uila. I mea e hoʻokō ai i nā koi o nā noi uila a me nā uila, ua loaʻa nā waiwai PPA i hoʻonui ʻia:

ʻO ka wela wela (HDT) ma luna o 270°C

ʻOi loa ka paʻa dimensional;

Ka ikaika kiʻekiʻe, ka modulus kiʻekiʻe, ka ikaika hopena kiʻekiʻe

Ke kahe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa no ka hana pololei

ʻO ka wela kiʻekiʻe a me ke kūpaʻa solder

ʻOi aku ka maikaʻi o ka pale uila

ʻEnekinia Mekini

Loaʻa nā waiwai PPA kiʻekiʻe no ka ʻoihana mīkini. I mea e hoʻokō ai i nā koi hoʻohana o nā ʻāpana ʻoihana mīkini, ua hoʻoikaika ʻia nā mea PPA i kēia mau waiwai:

ʻO ke kūpaʻa wela kiʻekiʻe, ka wela distortion wela ma luna o 270 ℃

Kūleʻa kemika

Ka ikaika kiʻekiʻe, anti-fatigue

ʻOi loa ka paʻa ʻana

Kūleʻa wai wela maikaʻi

Paipai ʻaila maikaʻi

Nā mea e pono ai i kēlā me kēia lā

Loaʻa i nā mea PPA kiʻekiʻe no nā mea e pono ai i kēlā me kēia lā nā waiwai piha maikaʻi loa. I mea e hoʻokō ai i nā koi noi ma ke kahua o nā mea e pono ai i kēlā me kēia lā, ua hoʻoikaika ʻia nā mea PPA i kēia mau waiwai:

Kūleʻa wela kiʻekiʻe

Ke kū'ē kemika, kū'ē i ka luhi

ʻO ka ikaika maikaʻi a me ka pono mechanical

ʻOi loa ka paʻa ʻana
