(2) Hoʻohana maʻamau ka resin Phenolic e like me ka mea hoʻopili.
(3) Hoʻohana pinepine ʻia ʻo Hexamethylenetetramine ma ke ʻano he lāʻau lapaʻau;Hoʻohana maʻamau ka calcium stearate e like me ka lubricant, i hoʻohana ʻia e pale i ka agglomerating a hoʻonui i ka wai.ʻO ka hana nui o ka additive ka hoʻomaikaʻi ʻana i ka hana o ke one i uhi ʻia.
(4) Lakiō kumu o ka Lakiō Hui (hapana nui, %) Wehewehe: Ke one maka 100 Ke one holoi, Phenolic resin 1.0-3.0 (kaumaha o ke one maka), Hexamethylenetetramine (waiwai 2) 10-15 (ke kaumaha o ka resin), Calcium stearate 5-7 (ke kaumaha o ka resin), Additives 0.1-0.5 (kaumaha o ke one maka).1:2) 10-15 (kaumaha o ka resin), Calcium stearate 5-7 (kaumaha o ka resin), Additives 0.1-0.5 (kaumaha o ke one maka).
Kaʻina hana hana
ʻO ke kaʻina hana hoʻomākaukau e pili ana i ka uhi anuanu, ka uhi mahana a me ka uhi wela.I kēia manawa, kokoke i nā mea a pau e hoʻohana i ka uhi wela.ʻO ke kaʻina hana uhi wela e hoʻomaʻamaʻa i ke one maka i kahi mahana, a laila hui a hoʻoulu me ka resin, urotropine aqueous solution a me ka calcium stearate i kēlā me kēia, a laila ʻoluʻolu, ʻoki a me ka pale.Ma muli o ka ʻokoʻa o ke ʻano, ʻokoʻa ke kaʻina hui.I kēia manawa, nui nā ʻano laina hana ma Kina.Aia ma kahi o 2000 ~ 2300 mau laina hana semi-akomi me ka hānai lima, a aia ma kahi o 50 mau laina hana piha piha i ka kamepiula, e hoʻomaikaʻi maikaʻi ana i ka hana pono a me ka paʻa o ka huahana.No ka laʻana, ʻo ka laina hana ʻike maka automated o xx Casting Co., Ltd. he 0.1 kekona ka mana o ka manawa hānai, ka pololei o ka mana wela wela o 1/10 ℃, a hiki ke nānā ʻia ke ʻano hui ʻana o ke one i nā manawa āpau ma o ka wikiō. , me ka pono hana o 6 tons / hola.
Pono o ka hana
ʻAno maikaʻi loa
Ua uhi ʻia me ka resin paʻa a ʻike ʻia e like me ke one maloʻo.ʻO ka maikaʻi maikaʻi loa ka fluidity maikaʻi loa, kūpono loa ia no nā koina one liʻiliʻi.
ʻOi aku ka maikaʻi o ka ʻili o ke one
Hoʻopili ʻia ʻo ia e ka pana ʻana, a ʻo ka ʻili o ke one one he mānoanoa a maʻalahi, hiki ke hoʻomaikaʻi maikaʻi i ka hoʻopau ʻana o ka ʻili o ka hoʻolei ʻana.
ʻO ke kumu kūʻai haʻahaʻa o ka hana ʻana i ka pūpū
He wahi hehee kiʻekiʻe kona a hiki ke hoʻohana ʻia no ka hana ʻana i ka pūpū, me ka emi ʻana o ke one, ke kumu kūʻai haʻahaʻa a ʻoi aku ka maikaʻi o ka ea permeability.
Ka ikaika kiʻekiʻe a me ka paʻa wela
me ka hoʻohana ʻana i ka resin phenolic thermoplastic, loaʻa iā ia ka ikaika kiʻekiʻe a me ke kūpaʻa wela, e hāʻawi iā ia i nā pono kūʻokoʻa i ka noi ʻana o kekahi mau ʻāpana mānoanoa a nui.
Ka lōʻihi o ka mālama ʻana i ke one
ʻO ka resin phenolic alkaline i hoʻohana ʻia i ke one i uhi ʻia he hydrophobic, ʻoi aku ka maikaʻi o ke kūpaʻa o ke one, ʻaʻohe koi kūikawā no ke kaiapuni mālama, ʻaʻohe emi nui o ka ikaika ma hope o ka mālama ʻana i ka wā lōʻihi.
Laulā o ka noi
He kūpono ke kumu one i uhi ʻia no ka hoʻolei ʻana i nā mea metala a pau.
