He Manaʻo o ka Dip Coating a me Dip Molding

Kaʻina hana o ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana

Hoʻopiʻi Luu

Ua ʻike ʻia ke kaʻina hana o ka hoʻohui ʻana i kahi mea plastik ma luna o kahi ʻāpana metala mua ka uhi ʻana. ʻO ka metala e uhi ʻia e like me ke ʻano, e ʻae i ka plastic a i ʻole ka polymer e hoʻopili iā ia i ka wā o ka hana. Ma mua o ke kuʻi ʻana, mālama ʻia nā ʻāpana (a i kekahi manawa nā ʻāpana holoʻokoʻa) i manaʻo ʻia no ke kuʻu ʻana a hoʻomāhana ʻia ma mua o ka hoʻokomo pono ʻia ʻana i loko o ka polymer wai (e.g. PVC plastisol ). Ma ka hoʻoluʻu ʻana, pili ka polymer wai i ka metala a hoʻopaʻa ʻia, e hopena ana i kahi ʻili palaki mānoanoa e hāʻawi ana i nā mea pale a me nā mea hoʻonaninani. Hāʻawi kēia ʻili i hoʻonui ʻia i ke kūʻē ʻana i nā ʻōpala, ʻaʻahu, corrosion, a me nā mea o waho me ka hoʻomaikaʻi ʻana i ka lōʻihi a me ka hoʻonui ʻana i ke ola lawelawe o nā ʻāpana metala. ʻAʻole hāʻawi wale ʻia ka ʻoluʻolu ʻo Dip coating akā e hōʻoiaʻiʻo nō hoʻi i ka palekana o ka mea hoʻohana ma o ka hāʻawi ʻana i kahi ʻili insulating me ka hoʻomaikaʻi ʻana i ka paʻa.

ʻO ka hoʻohana maʻamau o ka uhi ʻana i nā mea hana lima e like me nā pliers e pōmaikaʻi ana i ko lākou hiki ke hoʻopaʻa a hoʻopaʻa i nā mea paʻa ʻoiai e mālama ana i ka pono o ka mea hana ma hope o ka hoʻopili ʻana i ka uhi plastik ma nā lima. Hoʻohui ʻia, loaʻa ka pono i nā mea hoʻopili i nā huahana ʻē aʻe e like me nā kaʻa kūʻai, nā hīnaʻi, nā tweezers, nā poʻi, nā pāpale, nā pani a me nā mea ʻē aʻe, kahi e makemake ʻia ai ka rigidity.

Eia kekahi, ʻo nā ʻili plastik e lilo i mea hoʻokalakupua wela a me nā uila e hāʻawi ana i ka pale hou i ka wā e lawelawe ai i nā mea wela i nā mea hana lima e like me nā pliers a me nā ʻōpala; Hiki iā lākou ke hoʻohana ʻia no nā kumu insulation i nā mea uila e like me nā uea, nā uea, a me nā mea hana kikohoʻe.

Hoʻolulu ʻia

ʻO ke kaʻina hana o ka hoʻoheheʻe ʻia ʻana ua like ia me ke ʻano o ka uhi ʻana, me ka hoʻohui ʻana i kahi ʻanuʻu demoulding a wehe paha. ʻO ka hoʻoheheʻe ʻia ʻana e hiki ai ke hana i nā ʻāpana pā hoʻokahi, hollow, a me nā ʻāpana pā pālua, e hoʻopau ana i ka pono no nā kaʻina hana e like me ka ʻoki ʻana a me ka deburring. Loaʻa kēia i ka mālama waiwai maka ma muli o ka emi ʻana o nā hana lua. ʻO nā hiʻohiʻona o nā huahana plastik i hana ʻia ma o kēia kaʻina hana, ʻo ia nā mīkina lima latex, nā lole a me nā mea lole, nā kīʻaha, nā poʻi plastik, a me nā ʻāpana mea leʻaleʻa.

Ke ʻano o ka uhi ʻana a me ka Polymer Molding

ʻO nā polymers maʻamau i hoʻohana ʻia no ka uhi ʻana i nā mea me ka plastisol, latex, neoprene, polyurethane, a me ka epoxy. ʻO kahi hiʻohiʻona koʻikoʻi o kēia mau polymers ʻo ko lākou hiki ke loaʻa ma ke ʻano wai ma ka lumi wela me ka ʻole e koi i ka hana hou. Eia kekahi, ma mua o ka noʻonoʻo ʻana i ka hoʻohana ʻana i ka polymer wai i loko o ka uhi ʻana a me nā kaʻina hana hoʻoheheʻe ʻia, pono e loaʻa iā ia ka viscosity lawa e pale ai i ka holo nui ʻana mai ka ʻili o ka mold. No laila, kau ka polymer ma luna o ka ʻili a hiki i ka hoʻōla ʻana.

ʻO Plastisol

ʻO Plastisol, ka polymer i hoʻohana pinepine ʻia i ka hoʻoheheʻe ʻana a me nā kaʻina hana hoʻoheheʻe ʻia, aia ka polyvinyl chloride i hoʻopuehu maikaʻi ʻia (PVC) resin i loko o ka wai plasticizer. Ma ka hoʻomehana ʻana, hoʻopaʻa ʻia a maʻalili a maʻalili i loko o kahi mea palupalu a elastic me nā waiwai e like me ka lāʻau. Kaulana ʻia no kona ʻano paʻakikī, ka pale ʻana i ka corrosion, a me ka pale ʻana i ka hopena, kūpono loa nā uhi Plastisol no nā noi uila ma muli o ko lākou ikaika dielectric kiʻekiʻe. Eia kekahi, hiki ke hoʻohui ʻia nā kala e hoʻoponopono i ke ʻano o ka huahana hope.

Latex

ʻO ka emulsion o ka latex he mau ʻāpana polymer liʻiliʻi, me nā ʻāpana ʻōpala he 30-40% o ka huina. He mea koʻikoʻi ia i ka hana ʻana i ka lāʻau lapaʻau a hiki ke kūlohelohe a synthetic paha. Hiki ke maʻalahi ka polymer a ʻaʻohe pilikia o nā mea ʻawaʻawa. Eia naʻe, manaʻo kekahi mau haʻawina i ka wā e hoʻohaʻahaʻa ai i ka pauka, hiki i kekahi poʻe ke ʻike i nā hopena maʻi, e alakaʻi ana i ka emi ʻana o kona kaulana.

Neoprene

Hana ʻia ʻo Neoprene mai ka polymerization o ka rubber neoprene a he mea ʻokoʻa ia i ka latex. Ua ʻike ʻia no kona kūpaʻa a me ka maʻalahi.

ʻO Polyurethanes

Hoʻokumu ʻia nā polyurethanes me nā hui carbamate (a i ʻole ethyl carbamate) i hoʻopili ʻia e ka carbamate. Ua ʻike ʻia no kona maʻalahi a me ka elasticity kiʻekiʻe i ka deformation.

ʻO kaʻahu

ʻO ka Epoxy kahi polymer thermosetting, i ka wā e hoʻopili ʻia ai nā kaulahao polymer, e hana i kahi uhi o ka ikaika kiʻekiʻe, kemika a me ke kūpaʻa wela.
