lubricant graphite. Nā hiʻohiʻona ʻokoʻa
Ka haku mele a me nā ʻano
I kēia lā, ʻaʻole pili ka haku ʻana o ka graphite grease i nā lula koʻikoʻi. ʻO GOST 3333-80, ka mea i pani i ka GOST 3333-55 kahiko, ʻaʻole ia e hoʻokumu i ka quantitative a qualitative hoʻohui o nā mea i hoʻohana ʻia i ka hana ʻana i ka graphite grease. Hōʻike wale ka maʻamau i nā hiʻohiʻona maʻamau o ka graphite grease type "USsA" a me nā waiwai liʻiliʻi i koi ʻia.
Hoʻohana ʻia kēia e nā mea hana, e hoʻāʻo me ka haku mele a, ma muli o ka hopena, nā waiwai hope o ka huahana. I kēia mau lā, ʻelua mau mea ʻelua o nā mea nui o ka graphite grease: kahi kumu mineral mānoanoa (maʻamau o ka petroleum kumu) a me ka graphite lepo maikaʻi. Hoʻohana ʻia ka calcium a i ʻole lithium soap, ke kaomi nui, antifriction, ka hoʻopuehu wai a me nā mea hoʻohui ʻē aʻe e like me nā mea hoʻohui.
I kekahi manawa hoʻohui ʻia ka pauda keleawe i ka graphite. A laila kapa ʻia ka ʻaila copper-graphite. Ke neʻe nei ke ʻano o ka ʻaila keleawe-graphite i ka pale lōʻihi o ka hoʻopili ʻana i nā ʻili mai ka ʻino me ka liʻiliʻi o nā neʻe ʻana. No ka laʻana, hoʻohana nui ʻia kēlā lubricant i nā pilina pili a me nā alakaʻi like ʻole.
ʻO nā hiʻohiʻona o ka graphite grease, ma muli o ka haku mele, ʻokoʻa loa. No ka laʻana, ʻo ka haʻahaʻa haʻahaʻa loa i nalowale ʻole ai ka lubricant i kāna mau waiwai mai -20 a -50 ° C. Ka palena kiʻekiʻe: mai +60 (no ka lubricant UssA maʻalahi loa) a i +450 (no nā "graphites" kiʻekiʻe o kēia manawa).
ʻO kekahi o nā mea i ʻōlelo ʻia o ka graphite grease he haʻahaʻa haʻahaʻa o ka friction. Hoʻokō ʻia kēia ma muli o ka graphite, ʻo nā papa a me nā kristal o ia mea ma ka pae molecular e lele maikaʻi loa e pili ana i kekahi i kekahi a ma nā ʻaoʻao ʻē aʻe, me ka nānā ʻole i ke ʻano o kēia mau papa. Eia nō naʻe, ma muli o ka paʻakikī o nā kristal graphite pākahi, ʻaʻole ʻōlelo ʻia kēia momona no ka hoʻohana ʻana i nā ʻāpana friction me ka pololei o ka hana kiʻekiʻe a me nā wahi liʻiliʻi ma waena o nā ʻāpana pili. No ka laʻana, ua hōʻoia ʻia ʻo ka hoʻokomo ʻana i ka "graphite" ma kahi o nā momona kūpono ʻē aʻe (solidol, lithol, a me nā mea ʻē aʻe) i nā bearings rolling i hoʻemi i ko lākou ola lawelawe.
Hoʻoholo pū ka Graphite i nā waiwai conductive o ka lubricant. No laila, hoʻohana ʻia ka graphite grease e pale i nā pilina uila mai ka ʻinoʻino a me ka hoʻonui ʻana i ka sparking.
He aha ka mea i hoʻohana ʻia?
He ākea ka laulā o ka lubricant graphite. Ua hōʻoia maikaʻi ʻo Graphite iā ia iho i nā pālua friction ākea, kahi liʻiliʻi ka wikiwiki o ka neʻe ʻana o nā ʻāpana. ʻAʻole ia e holoi me ka wai no ka manawa lōʻihi, ʻaʻole maloʻo a ʻaʻole hoʻohaʻahaʻa ma lalo o ka mana o nā mea ʻē aʻe o waho.
I nā kaʻa maʻamau a me nā kaʻa, hoʻohana nui ʻia ka graphite grease:
- nā pilina pili - e pale aku i ka ʻino a me ka pipili ʻana o nā kaula;
- ʻO nā huila pōlele o nā huila hoʻokele - ma ke ʻano he lubricant nui i hoʻomoʻi ʻia i loko o ke kino o nā bearings a waiho ʻia ma lalo o nā anthers;
- nā hui hoʻokele a me nā ʻōlelo aʻoaʻo - hoʻohana ʻia ma ke ʻano like me nā bearings ball;
- nā pili spline - ua lubricated nā splines waho a me loko e hōʻemi i ka ʻaʻahu i ko lākou neʻe ʻana;
- nā pūnāwai - ua lubricated nā pūnāwai a me nā substrates anti-creak;
- nā pilina - ma ke ʻano maʻamau, ʻo ia nā pahu pākaukau, kahi uea maikaʻi ʻole mai ka pākaukau a i ke kino a me kahi uea maikaʻi mai ka pākaukau a i ka mea hoʻomaka;
- ma ke ʻano he papa anti-creak ma ka hoʻopili ʻana i nā ʻili plastik a me nā metala.
ʻOiai ʻo ka ʻoiaʻiʻo i kēia lā ke hāʻawi aku nei ka mākeke i kahi ākea o nā lubricants ʻoi aku ka holomua a hoʻololi ʻia, ke koi mau nei ka graphite i waena o nā kaʻa. He kaulike maikaʻi ma waena o ke kumukūʻai a me nā hiʻohiʻona. ʻO ke kumu kūʻai maʻamau no 100 grams o ka lubricant graphite fluctuates ma kahi o 20-30 rubles, ʻoi aku ka maikaʻi ma mua o nā haku lubricant hou me nā ʻano i hoʻomaikaʻi ʻia. A inā ʻaʻole koi ʻia kahi pale kiʻekiʻe, ʻo ka hoʻohana ʻana i ka graphite ka hopena kūpono loa.
