Nā Kaʻina Hana Hana o nā kiʻiʻoniʻoni PVC: Extrusion a Calendering

Hoʻohana nui ʻia nā kiʻiʻoniʻoni PVC i ka hoʻopili ʻana i ka meaʻai, ka mahiʻai, a me ka ʻoihana ʻoihana. ʻO ka extrusion a me ka calendering nā kaʻina hana nui ʻelua.

Extrusion: Loaʻa ka maikaʻi i ke kumu kūʻai

Hoʻopili ʻia nā kikowaena a puni kahi extruder screw. ʻO ka lako paʻa ka mālama ʻana i ka lewa a maʻalahi hoʻi e hoʻokomo a debug. Ma hope o ka hui ʻana i nā mea e like me ke ʻano, komo koke lākou i ka extruder. Ke hoʻololi ʻia ka wili i ka wikiwiki kiʻekiʻe, hoʻopili wikiwiki ʻia nā mea e ka ikaika shear a me ka hoʻomehana pololei. A laila, hoʻokuʻu ʻia lākou i loko o ke ʻano kiʻiʻoniʻoni mua ma o ke poʻo make i hoʻolālā maikaʻi ʻia, a hoʻomaʻamaʻa hope ʻia a hoʻohālikelike ʻia e nā huila hoʻoheheʻe a me ke apo ea. Hoʻomau ka hana me ka hana kiʻekiʻe.

ʻO ka mānoanoa o ke kiʻiʻoniʻoni mai 0.01mm a 2mm, kūpono i nā pono like ʻole. ʻOiai ka liʻiliʻi o ka ʻaʻahu i ka mānoanoa ma mua o nā kiʻiʻoniʻoni calendered, hana ia no nā huahana me nā koi haʻahaʻa haʻahaʻa. ʻO ka hoʻohana ʻana i nā mea hana hou e hōʻemi i nā kumukūʻai. Me ka haʻahaʻa haʻahaʻa lako hoʻokomo kālā a me ka ikehu hoʻohana, ia e kaumaha ana i ka nui loaʻa kālā. No laila, hoʻohana nui ʻia nā kiʻiʻoniʻoni extrusion i ka mahiʻai a me nā ʻāpana ʻenehana, e like me nā kiʻi ʻoniʻoni ʻōmaʻomaʻo a me nā kiʻi ʻoniʻoni ukana.

Kalendering: Hoʻohālikelike me ke ʻano kiʻekiʻe

ʻO nā mea hana o ke ʻano calendering i haku ʻia me nā wili hoʻomehana kiʻekiʻe kiʻekiʻe. ʻO nā mea maʻamau he ʻekolu-roll, ʻehā-roll a ʻelima paha kalena, a pono e hoʻoponopono pono ʻia nā wili e hōʻoia i ka pololei o ka hana. Hoʻohui mua ʻia nā mea e kahi kneader kiʻekiʻe, a laila e hoʻokomo i ka mixer i loko no ka plasticization hohonu, a ma hope o ke kaomi ʻia ʻana i loko o nā pepa e kahi wili hāmama, komo lākou i ka kalena. I loko o ka kalena, ua hoʻokuʻu ʻia nā ʻili a hoʻolōʻihi ʻia e nā huila wela he nui. Ma ka mālama ʻana i ka mahana a me ka spacing o nā wili, hiki ke hoʻopaʻa ʻia ka mānoanoa o ke kiʻi i loko o ± 0.005mm, a kiʻekiʻe ka palahalaha o ka ʻili.

Loaʻa i nā kiʻiʻoniʻoni PVC calendered ka mānoanoa like ʻole, nā waiwai mechanical kaulike, nā waiwai optical maikaʻi loa, a me ka ʻike kiʻekiʻe. I loko o ka pahu meaʻai, hōʻike lākou i ka meaʻai a hōʻoia i ka palekana. I nā huahana kiʻekiʻe o kēlā me kēia lā a me ka hoʻopili huahana uila, ʻo kā lākou ʻano maikaʻi e hoʻolilo iā lākou i koho kiʻekiʻe.

I ka hana ʻana i nā kiʻiʻoniʻoni PVC, inā ʻo ke kaʻina calendering a i ʻole ke kaʻina extrusion,Nā mea hoʻopaʻa paʻa PVCpāʻani i kahi kūlana koʻikoʻi.TopJoy Chemical'swai barium-zincamea hoʻokūpaʻa calcium-zincpale i ka PVC degradation i nā wela kiʻekiʻe, e hōʻoia i ka paʻa o nā mea waiwai, hoʻopuehu maikaʻi i ka ʻōnaehana PVC, a hoʻonui i ka pono hana. Welina mai e hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa a e kakali i ka launa pū ʻana me ʻoe!
