Ke kaʻina hana o ka loaa ana i kekahi varnish

I ka paka ia i ka haku mele 'ana, ka mea kēia mau pono hana e e hoʻohana: phenol,'eto ka waiʻona, formalin a me ka ammonia. He aha nō nā 'ano o ka bakelite lacquer ua ike? Ka mea, hilinaʻi ma luna o nā 'ano o constituent wahi.

Ano o ka constituent pono hana

No laila, ka mea mua waiwai - he phenol. He he aloha hui a hoike mai i ka hui 'ana me ka wai. Kona ke kūpaleʻana mehana He 40 ° C. Formalin - keia mea he pilikiaʻawahia waiwai, a ua noʻonoʻo i ka make. He He maopopo wai a me ka haahaa nui o ka reactivity. Ammonia ua i hoʻohana 'ia i loko o ke gula palapala akā, ka mea, ua i mai o ka poe ikaika ole koʻana koko pāʻoihana.

'eto waiʻona ua hoʻohana 'ia no ka pumping kalapona i loaʻa' ona. Ka hope hopena mea he maopopo wai. Ua hiki ke pena i loko o kekahi mau waihoʻoluʻu. ¶ A i loko o ka lacquer ka loaʻa nō hoʻi kaʻaila a me ka kelulose. Mamua o ohui ka mea, ae lawe ia'ku, lapaau.

I ka papa kuhikuhiE ano o

I kēia lā, he 9 ka papa kuhikuhi ano o bakelite lacquers. Kēlā me kēia no ia ua hoʻohana 'ia i loko o ka ua hana. Eia kekahi, ka mea, i kekahi mau pakeneka o constituent waiwai, a laila phenol, formaldehyde, ethanol a me ka ammonia. Me ka loli o ka nui o kekahi o na nā hoailona e hoʻololi i ka waiwai o ka varnish a me kona hana. No ka laʻana, ua hiki ke hoohalike lama ia varnishes:

• SBS-1 - no ka aaioee o ke ea a me ka plywood, a i hoʻohana i ka paia waho a me Kalaiaina mea hoʻonani o ka hale.

Ke varnish pili ana i ka ili o ke kūkuluʻana mea a eiiiiiaiou me ka palaki a me ka lole wili. Ka hopena hope ua hanaʻia ma luna o ka ili o ka kūikawā Auana iloko olaila o ke aloha a me'okanikaʻole hehee wale. Ka mea, i malama i ka ili, mai ona mau a me nā corrosive waiwai.

E ho ohana i ke kapili

ua kēiaʻano o ka lacquer hoʻohana no nā kūloko ma, a mawaho hana. Me ke kōkua o ke kūikawā kalameaʻai mea hiki ke kū i ka makemakeʻano o ka huahana. Nā waiwai o ka varnish koe ua hoʻololiʻia. Eia naʻe, kona hoʻohana i loko o ka hale, ua huikau. Mua ana i ka ili pono e ua holoiʻia o ka loa a me ka'ōpala maloʻo ia. Ma hope o ka penaʻana, ka varnish ili honua pono e welaʻia. Ka wela E hiki 160 ° C. E loaʻa ai i kēia, e ka mea e hana ai.

Natural ka maloʻoʻana ua lawe mai ma luna o kaʻilikai 4 hola. No ka oi hoʻokolokolo pono 'ohana ka palekana ua noi ma luna o ka lua, ahu iho a iloko ona i kakauia he maopopo filler. A pau o ka mea kēia i unfilled. Ultimately, ka ho film kona mānoanoa ihoiho 0.5 mm o.

No ka hoʻoikaika 'ana i ka me mechanical ikaika o ka' ilikai ua hoʻohana pulupulu lole i ua impregnated me ka bakelite varnish. Ua Ua hoonoho iho la ma 3, ahu iho. Kēia enehana Ua like penei: mua lole e holoi leʻa, a maloʻo, e pakele o ka pia.

Ua Ua oki i loko o ka poe liilii, lāʻau kī, a kupenu iho la i loko o ka ipu o ka HW. Ka mea, e alohaʻia no 5 minuke. Eia, i ka'aʻaʻa wehe 'ia mai ka ipu a me ka hoʻohana' laholio Loan wili. Na impregnated apana hoomanawanui i ka foxmike lewa, a maloʻo, no laila, i ke alo o ka'ūheheʻe ua minimized. Primed lole ua noi ia, a maloo ma luna o kaʻili, a ma luna me ka palaki noi lacquer. Inā ka mea i pono, e hoʻonui i ka ikaika me mechanical o ka paipu, ka lole ua okioki i loko o ka loloa o ka uuku ka laula. Ke kaʻina hana laila hele ma ka ia laina.

Ultimately ho film ua hanaʻia ma luna o ka ili o ka hana, a e hoomalu i ka mea mai ka waiū i ka ona a me ka 'ē aʻe. Ua hiki e poino ma lalo o kekahi mau kumu:

• ina oi aku 20 ° Cʻilikai mahana e e loli ai i ka lōʻihi manawa;
• ina lole komoʻuʻuku nona ka ili me ka lacquer, e pololei Map.

I loko nō o ka mea i ke kapili ana o bakelite varnish kumu no kekahi pilikia, e hoopono ana ma na hōʻike manaʻo o nā mea kūʻai mai, ua lako e koe he mahalo.

kumu kūʻai pilikino E pili

Ke kāki 'ole ka loa e lauwili, ke kaumaha ma muli o ka hao, e like me ka pono me ka hoʻohana' ia o ka lewa. Price o ia mau mea haʻilula keimikala mea i loko o ka laulā mai ka 300 a hiki i 1000 keneta hano.

ka hopena

E like me ka mea, e olelo aku i ka haku, bakelite varnish mea he kaulana mea i ka hoʻohana 'ole wale ma ka hana, akā, i loko o maʻamau o ke ola. Ua Ua hoʻohana 'ia no ka? Iecaianoaaiiuo o kela Nine Inch a me nāʻano makelia hou. People ka mea hana ia mau mea, e olelo aku i kona palapala noi enehana mea 'ano mea. Lakou wale Ua kuapo i e e hahai aku i kekahi mau rula e hana ana me ka HW wā. Ka mua iaʻi lakou wahi e e pono ventilated. Ua hiki ole e lōʻihi, e like me Punk na nahu o ka phenol alakai i kaʻapu kōheoheo.
