Mōlina o ke ea ma ka hale.

Ka lula ea Ke i kēia manawa i ka loa, he pono ole i loko o kā mākou kela la i keia ola ana. Lula ea ua hanaʻia kekahi mau oihana mua o ke kaa, na hale, nā mīkini home, a me ka lako, kīʻaha a me nā mea 'ē aʻe. Pinepine ea handyman ma ka hale ua hoʻohana 'ia me ka maka mea e paka i kekahiʻano o ka maikaʻi kēia' ikamu.

All Ka lula ea Ke i hoʻohana i ka paka hale kūʻai, māheleʻia i loko o nā pūʻulu: thermoplastic a me ka thermosetting.

Thermosets wehewehe aku ma ka i kā mākou paakiki a me ka palena iki plasticity e leie aku ia ia i maule ai hoopalupalu mai ka wā enaena.

I ka enaena i ka kekahi wela thermoplastics, e heheʻe, akā, inā i ka wela kulu hou i kupaa. Kēia waiwai mau hiʻohiʻona nō thermoplastics ka pahu kui mōlina ma ka hale, a me ka hana i nā kikoʻi.

He aha ka ka haku mele 'ana o nā lula ea? Pehea ea ua i ma kona home?

Homemade ea hiki e ua kālaiʻia i loko o ka kēia 'ano. Pono e loa poʻe'ē he maikai sawdust a me magnesite i loko o ka lākiō 2: 1, ninini ka hui kākoʻo pāʻoihana o 0,1% makanekiuma koloriside, a hookonokono ae ai me ka loaa i ka pasty moku'āina. I mea e loaa lāliʻi o ia mau lula ea Ke i hoʻohana walaʻauʻana ala - ka pahu kui mōlina ma ka hale i loko o shape. Ma solidification, ke ea e lilo loa ai kiʻekiʻe ikaika me ka maikai kaʻaeʻana e lapaʻau, 'o ia hoʻi, ia mea,ʻaʻole paʻakikī e? eou, i ike ai, lawelawe i ka abrasive mea paahana a me ka waihona.

He hiki i ka paka ea ole. He mea pono e hui pu ka lole lāʻau lepo me ka talc lepo i loko o ka lākiō 5: 2, a ninini i hoomakaukau mua nä lälä o ka glue. Ka lina E i ka hana mau o ka mānoanoa holika. Ke kūpono läÿau, ua pioloke pono no laila, e like me ka loaa i ka pasty moku'āina. Kupono e hoʻolauna i ka läÿau, he 2.1 hapa ma ka nuipa a potash alum, hoʻomalu i ka punahelu, a maoli ka maloʻoʻana aila, hoakaka loa ductility. ina makemake, ke ea hiki e nā pōpō. No keia pono e hou i ka haku mele 'ana o nā lula ea Ke aniline make makemake waihoʻoluʻu. No ka lāliʻi o ke ano o ka manufacturing - e mahiki ana ea i loko o ka hale i loko o shape. E hoomahuahua i ka ikaika o nā lula ea i loko o ka hui i ka manawa o ka hana kahi o ka glue i nininiʻia naʻe nitro a nitrocellulose lacquer. no hoi Details i i ma ka hoolei ana.

Good ano mea ea, i ka mea i hoomakaukauiaʻi mai ka kēia eiiiiiaiou: pepa maloo kaumaha / maloo kamana glue / he wili chalk / glycerol / ethanol / maloo ocher, e hui e like me ka māhele ma ke kaupaonaʻana o 5/28/60 / 2.5 / 3, 5/1.

Ua Ua ikaika pepe iho la ka maloo kaumaha o ka pepa a me ka ninini i ka nāu kekahi nä lälä o ka glue. Iloko o ka dilution E e i nā lawelawe glycerol, chalk, ocher a me ka waiʻona, nō hoʻohuihui ia. Mau māhele o kēia hui e hoʻohana i mōlina Ka lula ea Ke i loko o ka hale. Ke huahana Ua nā pōpō, ina hou a hiki i ka hui ana o aniline.

Phenol-formaldehyde Ka lula ea Ke i kekahi,ʻaʻole paʻakikī ke kukeʻana i ka hale. E pono e lawe mea pōaka (phenol) hydroxybenzene paha analogs a me ka koʻana koko pāʻoihana o 40% formalin. I kia carbolicʻakika mea oo hiki ia oe, e puku phenol. He mea pono e hui i ka mea pōaka phenol (20g) me ka formalin (30 g), ho onui i kia hydrochloricʻakika (30 kulu). Akā, i ka phenol hiki ke hoʻohana 'carbolicʻakika (40ml). I ka läÿau, E spontaneously hoʻa'ā i mai, a hoʻolapalapa, a e lilo i ka hana mau o glassy a me ka h ÷. Ke kūpono nuipa e ninini i loko o ka punahelu no 30 minuke ma hope i ka hui i loko o ka palapala bapetizo i nā kapuahi e ka wai no 10-15 minuke. A laila, e hiki ai ka huina hoonui wehe mai i ka punahelu. Pela i loaa kēpau - mea he thermosetting ea me ka ulaula kala like 'ole, he paakiki a me ka ikaika. Mai ia mea hiki i ka paka māhele mea i manao ia e hoolilo i ka nui wahie.
