He aha ka molybdenum disulfide?
ʻO ka molybdenum disulfide (MoS2) he mea hoʻoheheʻe paʻa koʻikoʻi, i kapa ʻia ʻo "ke aliʻi o ka lubrication paʻa"
1. ʻO ka molybdenum disulfide he pauka paʻa i hana ʻia mai ka pauka concentrate molybdenum maoli ma hope o ka hoʻomaʻemaʻe kemika.
2. He ʻeleʻele ka waihoʻoluʻu o ka huahana a ʻeleʻele hina hina, me ka luster metala, a manaʻo ʻia he pahee ke hoʻopā ʻia, a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai.
3. Loaʻa i ka huahana nā pōmaikaʻi o ka hoʻopuehu maikaʻi a me ka paʻa ʻole. Hiki ke hoʻohui ʻia i nā momona like ʻole e hana i kahi moku colloidal paʻa ʻole, e hoʻonui i ka lubricity a me ke kaomi nui o ka momona;
4. He kūpono hoʻi ia no ke kiʻekiʻe wela, ke kiʻekiʻe kiʻekiʻe, ka wikiwiki kiʻekiʻe a me nā kūlana hana mechanical load, a hoʻonui i ke ola lawelawe o nā mea hana;
5. ʻO ka hana nui o ka molybdenum disulfide i hoʻohana ʻia e like me ka friction material e hoʻemi i ka friction ma ka haʻahaʻa haʻahaʻa, e hoʻonui i ka friction ma ke kiʻekiʻe wela, a e hoʻemi i ka nalowale ʻana.
Hoʻohana i ka molybdenum disulfide (MoS2)
1. Lubrication ma lalo o ka laulā wela kūlana: ka pili pili o lubricating aila a me ka momona ma kahi o 60 ° C a 350 ° C. Molybdenum disulfide paa lubricant hiki ke hoohana ia i ka hana ana wela wela mai 270 ° C a 1000 C.
2. Lubrication ma lalo o ke kaumaha kaumaha kūlana: maʻamau, hiki i ka aila kiʻiʻoniʻoni o lubricating aila a me ka momona hiki ke hapai i ka haawe liilii. Ke ʻoi aku ka ukana ma mua o ka palena palena hiki iā ia ke amo, e haki ke kiʻi ʻaila a nahu ka ʻili ʻili. ʻO ka haʻawe maʻamau i hiki i ke kiʻi lubricating paʻa ke amo he 108Pa.
3. ʻO ka lubrication ma lalo o nāʻanoʻeleʻele: ma lalo o nā kūlana kiʻekiʻe,ʻo ka hoʻoheheʻeʻana o kaʻaila lubricating a me ka momona he mea nui, he mea maʻalahi ka hoʻopōʻinoʻana i ka'ōlohelohe a hoʻopili i ka hana hana o nā mea'ē aʻe. Hoʻohana maʻamau ka molybdenum disulfide lubricating mea no ka lubrication.
4. ʻO ka Lubrication ma lalo o nā kūlana radiation: Ma lalo o nā kūlana radiation, e polymerize a hoʻoheheʻe ʻia nā lubricants wai nui a nalowale ko lākou mau waiwai lubricating. Loaʻa i nā lubricants paʻa ke kūʻē i ka radiation.
5. Lubrication o conductive sliding ili: No ka laʻana, ka friction o conductive sliding ili, e like me ka uila pulupulu o ka uila kaʻa, conductive slider, lā ohi apo ma artificial ukali e hana ana i loko o ka hakahaka a me ka wili uila, hiki ke lubricated me ka composite mea haku. o ka kalapona graphite a metala paha.
6. Nā kūlana me nā kūlana kaiapuni maikaʻi ʻole: I nā kūlana kaiapuni koʻikoʻi, e like me ka mīkini kaʻa, ka mīkini ʻenekinia, ka metallurgical a me ka hao a me nā keʻena ʻoihana kila, nā mīkini mining a me nā ʻāpana hoʻoili ʻē aʻe e hana ana i ka lepo, sediment, kiʻekiʻe wela a me ka haʻahaʻa a me nā kaiapuni koʻikoʻi ʻē aʻe. i nā kūlana, hiki ke hoʻohana ʻia ka molybdenum disulfide solid lubricant no ka lubrication.
6. Ka pōʻino kino: No ka laʻana, hana nā ʻāpana hoʻoili o nā mīkini kai a me nā mīkini kemika i ka wai (ka mahu), ka wai kai, ka waika, ka alkali, ka paʻakai a me nā mea hoʻoheheʻe ʻē aʻe, a pono lākou e hana i nā pae like ʻole o ka ʻino kino. Hiki ke hoʻohana ʻia ka lubrication solid molybdenum disulfide no nā ʻāpana hoʻoili e hana ana i kēia kūlana.
7. ʻO nā wahi me nā kūlana kaiapuni maʻemaʻe loa: pono e pale aku i ka pollution, a me ka lubricant paʻa MoS2 hiki ke hoʻohana ʻia no ka lubrication.
8. Nā kūlana me ka mālama ʻole ʻia: ʻaʻole pono kekahi mau ʻāpana hoʻouna i ka mālama ʻana, a pono i kekahi mau ʻāpana hoʻouna e hōʻemi i nā manawa mālama i mea e mālama ai i nā kumukūʻai. I kēia mau manawa, kūpono ka hoʻohana ʻana o MoS2 solid lubricant, kūpono a hiki ke mālama kālā.
ʻO nā hiʻohiʻona molybdenum disulfide
ʻO ka hui molekala o MoS2: S=Mo=S
MoS2 mānoanoa: 4.5 – 4.8 g/cm ³
MoS2 CAS No.: 1317 -33-5
MoS2 Mohs paakiki: 1-1.5
ʻO ka helu hoʻoheheʻe MoS2: 0.03-0.05
Ka lōʻihi o ka pale wela o MoS2 (ka lewa): – 180 ℃ – 400 ℃
ʻO ke kūpaʻa paʻa ʻana o MoS2: ma kahi o 30000 kg/cm ²
ʻO ke kūpaʻa kemika o MoS2: he kūpaʻa ka corrosion ikaika a ʻaʻohe hopena koe wale nō ka waikawa nitric, aqua regia a me ka waika hydrochloric paila.
