Hana nui

a.Nā waiwai mīkini: ikaika kiʻekiʻe, kūpaʻa luhi, kūpaʻa dimensional, a me nā kolo liʻiliʻi (kakaikahi nā loli ma lalo o nā kūlana wela);
b.Heat aging resistance: hiki i ka UL temperature index i hoʻonui ʻia i ka 120 ~ 140 ℃ (ʻoi aku ka maikaʻi o ka wā kahiko o waho);

c.Ka pale ʻana o ka mea hoʻoheheʻe: ʻaʻohe māwae koʻikoʻi;

d.Paʻa i ka wai: maʻalahi e hoʻoheheʻe i ka pili ʻana me ka wai (e hoʻohana e akahele i ka wela kiʻekiʻe a me ka haʻahaʻa kiʻekiʻe);

e.Hana uila:

1. ʻO ka hana insulation: maikaʻi loa (hiki iā ia ke mālama i ka hana uila paʻa ma lalo o ka haʻahaʻa a me ka wela kiʻekiʻe, he mea kūpono ia no ka hana ʻana i nā ʻāpana uila a me nā ʻāpana uila);

2. Ka helu dielectric: 3.0-3.2;

3. Kū'ē Arc: 120s

f.Hiki ke hoʻoheheʻe ʻia: hoʻoheheʻe ʻia a i ʻole extrusion hoʻoheheʻe ʻia e nā mea hana maʻamau.Ma muli o ka wikiwiki o ka crystallization a me ka maikaʻi o ka wai, ʻoi aku ka haʻahaʻa o ka mahana ma mua o nā plastics ʻenehana ʻē aʻe.I ka hoʻoponopono ʻana i nā ʻāpana pā lahilahi, he mau kekona wale nō ia, a he 40-60 wale nō ia no nā ʻāpana nui.

palapala noi

a.Nā lako uila: nā mea hoʻohui, nā ʻāpana hoʻololi, nā mea pono hale, nā ʻāpana ʻāpana, nā uhi uila liʻiliʻi a i ʻole (kūʻai wela, pale ʻana i ke ahi, hoʻoheheʻe uila, hiki ke hoʻoheheʻe ʻia);

b.Kaʻa:

1. ʻO nā ʻāpana o waho: ʻo ka hapa nui o nā kihi kihi, uhi puka makani engine, etc.;

2. Nā ʻāpana o loko: ʻo ka hapa nui o ka endoscope noho, wiper brackets a me nā ʻōnaehana hoʻokele;

3. ʻO nā ʻāpana uila kaʻa: nā ʻili uila wiliwili kaʻa a me nā mea hoʻohui uila, etc.

c.ʻO nā mea hana mīkini: ke kāʻei kāʻei o ka mea hoʻopaʻa leo wikiō, ka uhi kamepiula uila, ka uhi kukui mercury, ka uhi hao uila, nā ʻāpana mīkini bakena a me nā mea he nui, nā kāmela, nā pihi, nā pahu wati uila, nā ʻāpana kamera ( me ke kūpale wela, nā koi hoʻopale ahi)

Hoʻopaʻa

Ma muli o nā pono like ʻole, hiki iā ʻoe ke koho i nā adhesives:

1. G-955: One-component lumi wela ho'ōla palupalu elastic shockproof adhesive, kū'ē i ke kiʻekiʻe a me ka haʻahaʻa wela, akā naʻe ka wikiwiki o ka hoʻopaʻa ʻana, hoʻokahi lā a i ʻole kekahi mau lā e hoʻōla ai ke kāpili.

2. KD-833 hikiwawe i hiki ke ho'opa'a i ka plastik PS i loko o kekahi mau kekona a he 'umi kekona, akā, he pa'akikī a he palupalu ka papa ho'opa'a, a 'a'ole kū'ē i ka ho'okomo 'ana i ka wai wela ma luna o 60 degere.

3. QN-505, ʻelua ʻāpana ʻāpana, ʻāpana palupalu palupalu, kūpono no ka hoʻopaʻa ʻana a i ʻole ka hui pū ʻana o PS.Akā ʻilihune ka pale wela kiʻekiʻe.

4. QN-906: ʻElua mau mea hoʻopili, pale wela kiʻekiʻe.

5. G-988: One-component lumi lumi wela vulcanizate.Ma hope o ka ho'ōla ʻana, he elastomer me ka wai maikaʻi ʻole, hoʻopili shockproof, kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.Inā ʻo 1-2mm ka mānoanoa, e hoʻōla maoli ia i nā hola 5-6 a loaʻa kahi ikaika.He 24 mau hola e ho'ōla piha ai.ʻO ka mea hoʻokahi, ʻaʻohe pono e hoʻohui, e hoʻopili wale ma hope o ka extruding a hoʻokuʻu iā ia me ka wela ʻole.

6. KD-5600: UV curing adhesive, hoʻopaʻa i nā pepa PS akaka a me nā papa, hiki ke hoʻokō i kahi hopena ʻole, pono e hoʻōla ʻia e ke kukui ultraviolet.He nani ka hopena ma hope o ka pipili.Akā ʻilihune ka pale wela kiʻekiʻe.

Hana waiwai

Maikaʻi uila insulation (ʻoi loa kiʻekiʻe-frequency insulation), kala ole a me ka malamalama, malamalama transmittance lua wale no i ka plexiglass, kala, ka wai kū'ē, maikaʻi kemika paʻa, awelika ikaika, akā brittle, oluolu e kumu stress brittleness, a me ka intolerance Organic solvents e like me benzene a me ka ʻaila.He kūpono no ka hana ʻana i nā ʻāpana alohilohi, nā ʻāpana hoʻonaninani, nā mea hana kemika, nā mea optical a me nā ʻāpana ʻē aʻe.

Hoʻokumu i ka hana

⒈Amorphous mea, haʻahaʻa moisture absorption, ʻaʻole pono e hoʻomaloʻo piha ʻia, ʻaʻole maʻalahi ka decompose, akā nui ka coefficient o ka hoʻonui ʻana i ka wela, a maʻalahi ka hana ʻana i ke koʻikoʻi kūloko.Loaʻa iā ia ka wai maikaʻi a hiki ke hoʻoheheʻe ʻia e ka mīkini wili a i ʻole plunger injection.

⒉Apono ʻia e hoʻohana i ke kiʻekiʻe o ka mea wela, ke kiʻekiʻe kiʻekiʻe o ka hoʻoheheʻe ʻana, a me ke kaomi haʻahaʻa haʻahaʻa.ʻO ka hoʻolōʻihi ʻana i ka manawa injection he mea maikaʻi ia e hōʻemi i ke koʻikoʻi o loko a pale i ka shrinkage a me ka deformation.

⒊ Hiki ke hoʻohana ʻia nā ʻano ʻīpuka like ʻole, a pili nā ʻīpuka me nā ʻāpana plastik i mea e pale ai i ka pōʻino i nā ʻāpana plastik ke wehe ʻia ka puka.Nui ke kihi demolding a ʻano like ka hoʻokuke ʻana.ʻO ka mānoanoa o ka pā o nā ʻāpana plastik he ʻano like ʻole, ʻoi aku ka maikaʻi me ka ʻole o nā mea hoʻokomo, e like me Kekahi mau mea hoʻokomo pono e hoʻomehana ʻia.

hoʻohana

Hoʻohana nui ʻia ʻo PS ma ka ʻoihana optical no ka maikaʻi o kāna transmittance māmā.Hiki ke ho'ohana 'ia no ka hana 'ana i ke aniani opua a me nā mea kani, a me nā waiho'olu'u māmā a'ōlinolino paha, e like me nā pale kukui, nā mea hana kukui, a me nā mea'ē a'e.No ka mea he mea paʻakikī ka pākiki PS, pono e hoʻohana i ke kāpili PS ʻoihana e hoʻopaʻa i ka ʻoihana.

ʻO ka hoʻohana ʻana iā PS wale nō ma ke ʻano he huahana he kiʻekiʻe brittleness.ʻO ka hoʻohui ʻana i kahi liʻiliʻi o nā mea ʻē aʻe i ka PS, e like me ka butadiene, hiki ke hōʻemi nui i ka palupalu a hoʻomaikaʻi i ka paʻakikī.Ua kapa ʻia kēia plastic i ka hopena-resistant PS, a ua hoʻomaikaʻi maikaʻi ʻia kona mau waiwai.Nui nā ʻāpana mechanical a me nā ʻāpana me ka hana maikaʻi loa i hana ʻia mai nā plastics.
