Nā Kumu Lubricant
He aha ka NLGI o nā momona i ka wā e hiki mai ai i nā momona?
Ua hoʻokumu ka National Lubricating Grease Institute (NLGI) i kahi hoʻohālikelike maʻamau no ka lubricating greases. ʻO ka helu kūlike NLGI (ʻike ʻia ʻo "NLGI grade") maʻamau no ke ana o ka paʻakikī pili o kahi momona i hoʻohana ʻia no ka lubrication. ʻOi aku ka nui o ka helu NLGI, ʻo ia hoʻi, ʻoi aku ka paʻa o ka momona.
ʻO ke kūlike ka ana o nā waiwai kino kumu o ka momona e hōʻike ana i ka paʻakikī o ka momona, hiki ke hoʻololi ʻia ma o ka hoʻololi ʻana i ka ʻiʻo mānoanoa.
ʻAʻole lawa ka helu kūlike o ka NLGI no ka wehewehe ʻana i ka momona e koi ʻia e kekahi noi. E nānā mau i ka puke a kou haku no ke ʻano momona i ʻōlelo ʻia.
Hōʻike ka papa ma lalo i ka hoʻohālikelike ʻana o ka NLGI a hoʻohālikelike i kēlā me kēia papa me nā huahana hale o ka like like.

NLGI Papa 000-NLGI 0 momona
Noi: NLGI Grade 000-NLGI 0 ua paipai ʻia no ke kaomi kiʻekiʻe, hana kaumaha a me ka ʻōnaehana pani.
Pōmaikaʻi: ʻO ka hana lubricity maikaʻi, pumpability maikaʻi, ʻoi aku ka maikaʻi o ka wela.
Nā hemahema: He maʻalahi ke ʻike ʻia ka hoʻokaʻawale ʻana i ka aila.
NLGI 1- 2
ʻO ka maʻamau ʻo NIGI 2 ka maʻamau a kaulana loa i ka hapa nui o nā momona, he mau momona maʻamau. Akā i nā noi kūpono, e koi ʻia nā noi like ʻole a i ʻole nā mea hana like ʻole Nlgi Grease.
Pōmaikaʻi: ākea ākea o nā noi, kūpaʻa colloidal maikaʻi
Ka helu NLGI kūlike ≠Viscosity
Nīnau ka mea kūʻai: Ke ʻimi nei au i hoʻokahi greases mānoanoa...
ʻO ka hale hana Lubircant: Makemake ʻoe i ka momona "ʻoi aku ka paʻakikī" a i ʻole ka ʻaila "stickier" hou aʻe?
Mea kūʻai: He aha ka ʻokoʻa ma waena o kēia mau mea ʻelua?
ʻO ka mua Nlgi Papa (Consistency & Penetration ) no nā huahana Grease wale nō
A ʻo ka viscosity no ka ʻaila lubricating a i ʻole ka aila kumu o nā huahana greases.
Hoʻonohonoho nā māka NLGI i ka momona palupalu a paʻakikī paha, kū ia no ke ʻano o ka momona.
viscosity classify grease base oil viscosity,Hoʻoholo ia i ka momona viscosity， ʻO ke kiʻekiʻe o ka viscosity, a ʻoi aku ka paʻa o ka momona.
ʻO ka maʻamau, loaʻa i nā greases 2 ka helu NLGI like akā ʻokoʻa loa nā viscosity base-aila, aʻo ʻelua mau mea ʻē aʻe i like ka base-aila viscosity akā ʻokoʻa nā māka NLGI, ʻo ia ke kūlana maʻamau i nā huahana greases.
ʻO ia ke kumu i hoʻomaopopo pono ai mākou i ka makemake maoli o ka mea kūʻai aku.
