Helu paona lole non woven

Loaʻa i nā lole i ulana ʻole ʻia i kā lākou ana ponoʻī no ka mānoanoa a me ke kaumaha. ʻO ka maʻamau, helu ʻia ka mānoanoa ma nā millimeters, ʻoiai ke kaupaona ʻia ma nā kilokani a i ʻole nā ​​tona. E nānā kākou i nā ʻano ana kikoʻī no ka mānoanoa a meke kaumaha o nā lole i ulana ʻole ʻia.

Ana ʻana no nā lole i ulana ʻole ʻia

He kaumaha ko kēlā me kēia mea, e like me ka lole i ulana ʻole ʻia a mākou e kamaʻilio nei i kēia lā. No laila pehea e helu ai i ke kaumaha o ka lole i ulana ʻole ʻia?

Ma ka helu ʻana i ke kaumaha a me ke kaumaha o nā lole i ulana ʻole ʻia, ʻehā mau ʻāpana i hoʻohana mau ʻia: hoʻokahi ka pā, i hoʻopau ʻia ʻo Y ma ka ʻōlelo Pelekania; ʻO ka lua he mau mika, i hoʻopau ʻia e like me ka m, ʻo ke kolu he grams, i hoʻopau ʻia e like me ka grams, a ʻo ka hā he millimeters, i pōkole ʻia e like me mm.

Helu helu lōʻihi

Ma nā ʻōlelo kikoʻī, hoʻohana ʻia ka nui a me ka mika e helu i ka lōʻihi. I loko o ka hana lole lole ʻaʻole i ulana ʻia, hoʻohana mau ʻia ka mika e like me ka ʻāpana o ka lōʻihi, a ʻo nā ʻāpana ana o ka lōʻihi me nā mika, kenimika, millimeters, a me nā mea ʻē aʻe. ʻO nā kikoʻī maʻamau i hoʻohana ʻia he 2.40 mika, 1.60 mika, a me 3.2 mika. No ka laʻana, i ka hana ʻana i ka lole i ulana ʻole ʻia, e loaʻa i kēlā me kēia kaʻina hana kahi lōʻihi kikoʻī, e like me "ka hana ʻana i nā mika X o ka lole ʻaʻole i ulana ʻia i loko o ka mīkini hoʻokahi".

Ka helu kaumaha

No ka loaʻa ʻana o ka lōʻihi a me ka laula, aia kahi mānoanoa? Pololei, aia nō. E like me nā kūlana honua, ʻo nā ʻāpana o ke ana ʻana no ke kaumaha he mau grama (g), kilokani (kg), etc. e pili ana ka grams i ke kaumaha o ka gram square, ʻo ia ka g/m ^ 2. No ke aha e hoʻohana ʻole ai i nā millimeters? ʻOiaʻiʻo, hoʻohana pū ʻia nā millimeters, akā ʻaʻole i hoʻohana ʻia. He lula ʻoihana kēia. ʻOiaʻiʻo, hiki ke like ke kaumaha o ka gram square me ka millimeters i ka mānoanoa, ʻoiai ke kaumaha o nā lole i ulana ʻole ʻia mai 10g/㎡ a i 320g/㎡. Ma keʻano laulā, ʻo ka mānoanoa o ka lole i ulana ʻole ʻia he 0.1mm, a ʻo ke kaumaha o kēlā me kēia mika square he 30g, no laila ʻo ke kaumaha o ka 100 mika o ka lole i ulana ʻole ʻia he 0.3kg.

Helu wahi

ʻO nā ʻāpana maʻamau o ka ʻāpana he mau mika square (mika square), nā iwilei, nā kapuaʻi square, a me nā mea ʻē aʻe. ʻO ka mānoanoa maʻamau o ka lole i ulana ʻole ʻia he 0.1mm ~ 0.5mm, a ʻo ka helu ʻana o ka ʻāpana e pili ana i ke kaumaha o ka mika square (g/㎡). No ka laʻana, inā he 50 grams ke kaumaha o hoʻokahi mika square o ka lole i ulana ʻole ʻia, a laila ua kapa ʻia ka lole i ulana ʻole ʻia he 50 grams lole i ulana ʻole ʻia (ʻike pū ʻia ʻo 50g/㎡ lole ʻaʻole i ulana ʻia).

Paʻakiki (feel)/Gloss

I kēia manawa, liʻiliʻi loa nā mea hana a me nā mea hana no ka hoʻāʻo ʻana i ka paʻakikī o nā lole i ulana ʻole ʻia ma ka mākeke, a hoʻāʻo ʻia lākou ma muli o ka manaʻo lima.

ʻO kanā palena tensile o nā lole i ulana ʻole ʻia

Loaʻa i nā lole i ulana ʻole ʻia nā ʻāpana tensile longitudinal a transverse. Inā huki ʻole ʻia, paʻi ʻia, hoʻokuʻu ʻia a hoʻoheheʻe ʻia, ʻaʻole nui ka ʻokoʻa o nā ikaika tensile longitudinal a transverse.

Ma lalo o ka umekaumaha o ka Honua, ua like ke kaumaha a me ka nuipaʻa, akā ʻokoʻa nā ʻāpana o ke ana. ʻO ke kaumaha o kekahi mea me ka nuipaʻa o 1 kilokani ke kau ʻia i ka ikaika o waho o 9.8 Newtons ua kapa ʻia ʻo 1 kilokani paona. ʻO ka mea maʻamau, hoʻohana mau ʻia nā ʻāpana nui ma kahi o ke kaumaha, i hoʻonui nui ʻia e ka wikiwiki ʻumekaumaha. Ma Kina kahiko, ua hoʻohana ʻia ka jin a me nā liang ma ke ʻano he mau ʻāpana kaumaha. Hoʻohana pū ʻia nā paona, auneke, carats, etc.

ʻO nā ʻāpana nui i hoʻohana pinepine ʻia he micrograms (ug), milligrams (mg), grams (g), kilokani (kg), tons (t), etc.

Nā hihia hoʻololi ana

1. Pehea e hoʻololi ai i ke kaumaha o ka lole mai ka g/㎡ a i ka g/mika?

ʻO 50g/㎡ ka waiwai o nā pou hoʻolaha ʻole i ulana ʻia. ʻEhia ka nui o nā mea maka e pono ai no ka hana ʻana i ka lole 100 mika ka lōʻihi? No ka mea he 50g/㎡ ka lole i ulana ʻole ʻia, ʻo ke kaumaha o ka 1 mika square he 50 grams. Ma kēia helu helu ʻana, ʻo ke kaumaha o ka lole 100 square meter non-woven he 50 grams * 100 square meters=5000 grams=5 kilokani. No laila, ʻo ke kaumaha o ka lole 100 mika ka lōʻihi ʻaʻole i ulana ʻia he 5 kilokani/100 mika=50 grams/mika.

2. Pehea e hoʻololi ai i nā grams i kahi?

ʻO ke anawaena o ka lole i ulana ʻole ʻia he 1.6m, ʻo ka lōʻihi o kēlā me kēia ʻōwili ma kahi o 1500 mika, a ʻo ke kaumaha o kēlā me kēia ʻōwili he 125kg. Pehea e helu ai i ke kaumaha o ka mika square? ʻO ka mua, e helu i ka nui o ka ʻāpana o kēlā me kēia ʻōwili lole i ulana ʻole ʻia. ʻO ka ʻāpana pōʻai me ke anawaena o 1.6 mika ʻo π * r ²， Ma waena o lākou, r=0.8m, π ≈ 3.14, no laila ʻo ka ʻāpana o kēlā me kēia ʻōwili o ka lole i ulana ʻole ʻia he 3.14 * 0.8 ²≈ 2.01 mau mika square. He 125 kilokani ke kaumaha o kēlā me kēia ʻōwili, no laila, ʻo ke kaumaha o ka mika square he 125 grams no ka mika square ÷ 2.01 mika square no ka ʻōwili ≈ 62.19 kalama o ka mika square.

Ka hopena

Hōʻike kēia ʻatikala i ke ʻano hoʻololi o ke ana mīkini lole lole ʻole, me ka helu ʻana o ka ʻāpana, ke kaumaha, ka lōʻihi, a me nā mea ʻē aʻe. I ke kaʻina hana o nā lole i ulana ʻole ʻia, ʻike pinepine ʻia nā pilikia ana. ʻOiai ke hoʻohana ʻia ke ʻano hoʻololi kūpono no ka helu ʻana, hiki ke loaʻa nā hopena pololei.
