ʻO ka Polyamide (PA) kahi polymer i loaʻa nā pūʻulu amide hou ma ke kaulahao nui.Kapa pinepine ʻia ʻo Nylon, ʻo PA kekahi o nā plastics ʻenekinia mua loa i kūkulu ʻia a hoʻohana nui ʻia.Ma kēia ʻatikala i kēia lā,Qingdao Sainuoe lawe iā ʻoe e ʻike i nā kumu nui he ʻumi o ka hoʻololi ʻana o ka nylon.

pp waxno ka Nylon i hoololiia

ʻO nā mea kūikawā o ka nylon e hoʻohana nuiʻia i nā kaʻa, nā mea uila a me nā mea uila, ka mechanical structure, nā mea haʻuki, nā lole a me nā mea'ē aʻe.Eia nō naʻe, me ka miniaturization o nā kaʻa, ka hana kiʻekiʻe o nā lako uila a me ka uila, a me ka wikiwiki o ke kaʻina hana o nā mīkini mīkini māmā, ke piʻi mālie nei ke koi no ka nylon a me kāna hana.No laila he mea nui ka hoʻololi ʻana o ka nylon.
Nā mea e pono ai ka nānā ʻana i ka hoʻololi ʻana i ka nylon
1. Ka hoʻonohonoho ʻana o ka mahana barela
(1) No ka mea, he polymer crystalline ka nylon, maopopo kona wahi hehee.ʻO ka mahana barela o ka resin nylon i ka hoʻoheheʻe ʻana e pili ana i nā waiwai o ka resin, nā mea hana a me ke ʻano o ka huahana.
(2) He mea maʻalahi ke kiʻekiʻe o ka wela o ka waiwai ke hoʻololi i ka waihoʻoluʻu, brittleness a me ka uea kālā, ʻoiai ʻoi aku ka haʻahaʻa haʻahaʻa haʻahaʻa e paʻakikī ai ka mea a hiki ke hōʻino i ka make a me ka wili.
(3) ʻO ka mea maʻamau, ʻo ka mahana hehee haʻahaʻa loa o PA6 he 220 ℃ a ʻo PA66 he 250 ℃.Ma muli o ka maikaʻi ʻole o ka wela o ka nylon, ʻaʻole kūpono ka noho ʻana i loko o ka pahu no ka manawa lōʻihi i ka wela kiʻekiʻe, i ʻole e hoʻoneʻe a me ka melemele o nā mea.I ka manawa like, ma muli o ka wai maikaʻi o ka nylon, kahe wikiwiki ia ke ʻoi aku ka mahana ma mua o kona wahi hoʻoheheʻe.
2. Hoʻonohonoho wela mold
(1) Loaʻa i ka mahana o ka mold kekahi mana i ka crystallinity a me ka hoʻoheheʻe ʻana.ʻO ka mahana wela mai 80 ℃ a 120 ℃.ʻO ka wela kiʻekiʻe, ka crystallinity kiʻekiʻe, hoʻonui i ka pale ʻana i ka lole, ka paʻakikī, ka modulus o ka elasticity, ka emi ʻana o ka wai, ka hoʻonui ʻia ʻana o ka molding, kūpono no nā huahana mānoanoa;
(2) Inā ʻoi aku ka mānoanoa o ka pā ma mua o 3 mm, ua ʻōlelo ʻia e hoʻohana i kahi pā haʻahaʻa haʻahaʻa me 20 ~ 40 ℃.No nā mea aniani i hoʻoikaika ʻia, pono ke kiʻekiʻe o ka mahana ma mua o 80 ℃.

3. Wall mānoanoa o nā huahana
ʻO ka lōʻihi kahe o ka nylon he 150-200, ʻaʻole liʻiliʻi ka mānoanoa o ka pā o ka huahana ma mua o 0.8mm, maʻamau 1-3.2mm, a pili ka shrinkage o ka huahana i ka mānoanoa pā o ka huahana.ʻOi aku ka mānoanoa o ka pā, ʻoi aku ka nui o ka emi ʻana.
4. Hoʻopau
ʻO ka waiwai nui o ka resin nylon ma kahi o 0.03mm, no laila e hoʻomalu ʻia ka lua o ka lua ma lalo o 0.025.
5. Ka holo a me ka puka
ʻAʻole e emi ke anawaena o ka puka o ka puka ma mua o 0.5T (t ka mānoanoa o ka ʻāpana plastik).Me ka puka i loko o ka wai, he 0.75mm ka palena iki o ka puka.
6. ʻO ke aniani fiber hoʻopiha piha
I ke kaʻina hana o ka nylon molding, hoʻemi i ka mahana o ka mold, hoʻonui i ke kaomi injection a me ka hoʻohaʻahaʻa ʻana i ka mahana o ka mea e hoʻemi ai i ka emi ʻana o ka nylon i kekahi ʻano, e hoʻonui i ke koʻikoʻi o loko o ka huahana a maʻalahi ka deform.No ka laʻana, ʻo ka emi ʻana o PA66 he 1.5% ~ 2%, ʻo ka emi ʻana o PA6 he 1% ~ 1.5%, a hiki ke hoʻemi ʻia ka emi ʻana ma kahi o 0.3% ma hope o ka hoʻohui ʻana i ke aniani fiber additive.
Hōʻike ka ʻike maʻamau iā mākou i ka hoʻohui ʻia ʻana o ka fiber aniani, ʻoi aku ka liʻiliʻi o ka hoʻoheheʻe ʻana o ka resin nylon.Eia nō naʻe, inā hoʻohui nui ʻia ka fiber aniani, e hoʻoulu ʻia ka fiber lana ma luna o ka ʻili, maikaʻi ʻole a me nā hopena ʻē aʻe.ʻO ka maʻamau, maikaʻi ka hopena o ka hoʻohui ʻana i ka 30%.
7. Hoʻohana i nā mea hana hou
ʻOi aku ka maikaʻi ʻaʻole e ʻoi aku ma mua o ʻekolu mau manawa e pale aku ai i ka discoloration o ka huahana a i ʻole ka emi ʻana o nā waiwai kino a me ka mechanical.Pono e mālama ʻia ka nui o ka noi ma lalo o 25%, ʻoi aku ka nui o ke kumu o ka loli ʻana o nā kūlana kaʻina, a e hoʻomaloʻo ʻia ka hui ʻana o nā mea hana hou a me nā mea hou.
8. Nā kuhikuhi palekana
I ka hoʻomaka ʻana o ka resin nylon, pono e hoʻohuli mua ʻia ka mahana o ka nozzle, a laila e wela ka mahana i ka pahu hānai.Ke ālai ʻia ka nozzle, ʻaʻole loa e kū i ka lua e hoʻoheheʻe ʻia, i mea e pale aku ai i ka hoʻokuʻu koke ʻana o ka heheʻe i loko o ka pahu hānai ma muli o ka hōʻiliʻili ʻana o ke kaomi, hiki ke pilikia.

9. Ke noi o ka mea hoʻokuʻu
ʻO ka hoʻohana ʻana i kahi mea hoʻokuʻu liʻiliʻi e hiki ke hoʻomaikaʻi a hoʻopau i ka ʻōpū a me nā hemahema ʻē aʻe.ʻO ka mea hoʻokuʻu o nā huahana nylon hiki ke zinc stearate a me ka aila keʻokeʻo, a i hui pū ʻia i loko o ka paʻi.Pono e liʻiliʻi ka nui o ka mea hoʻokuʻu i mea e pale ai i nā hemahema o ka ʻili.Pono e hoʻokuʻu ʻia ka wili i ka wā e pani ʻia ai ka mīkini e pale ai i ka haki ʻana o ka wili i ka wā o ka hana hou.

10. Mahope o ka lapaau ana
(1) Pono e mālama ʻia nā huahana ma hope o ka hana ʻana
ʻO nā ʻano maʻamau i ka ʻaila mineral, glycerin, paraffin wai a me nā wai hoʻolapalapa kiʻekiʻe ʻē aʻe, ʻo ka mahana mālama wela he 10 ~ 20 ℃ kiʻekiʻe ma mua o ka mahana hoʻohana, a ʻo ka manawa mālama e pili ana i ka mānoanoa o ka pā o ka huahana.ʻO ka mānoanoa ma lalo o 3 mm he 10 ~ 15 min, ʻo ka mānoanoa he 3 ~ 6 mm, a ʻo ka manawa he 15 ~ 30 min.ka huahana ma hope o ka hoʻomaʻamaʻa ʻana i ka wela e hoʻomālili mālie ʻia i ka lumi wela, i mea e pale ai i ka hoʻolili koke ʻana mai ka hoʻoulu hou ʻana o ke kaumaha i loko o ka huahana.
(2) Pono e mālama ʻia nā huahana me ka mana haʻahaʻa ma hope o ka hana ʻana
Hoʻohana nui ʻia ka mana humidity no nā huahana me ka haʻahaʻa kiʻekiʻe.ʻElua mau ʻano: ʻo ka hoʻolapalapa ʻana i ka haʻahaʻa wai;ʻO ka mea ʻē aʻe ʻo ke kaʻina wai o ka pāhaʻi acetate aqueous solution (ʻo ka ratio o ka potassium acetate i ka wai he 1.25:1, kahi paila 121 ℃).
He mea maʻalahi ka wai paila, inā lōʻihi ka waiho ʻana o ka huahana i loko o ke kaiapuni o 65% humidity, i hiki ai ke hōʻea i ka equilibrium moisture absorption, akā lōʻihi ka manawa.ʻO ka mahana hoʻomaʻamaʻa o ka pāhaʻi acetate aqueous solution he 80 ~ 100 ℃, a ʻo ka manawa lapaʻau e hilinaʻi nui ʻia i ka mānoanoa o ka pā huahana, i ka wā o ka mānoanoa o ka pā he 1.5mm, ma kahi o 2h, 3mm, 8h, 6mm, 16 ~ 18h.
