ʻO ka lole lole ulana ʻole SMS mai a | JINHAOCHENG

ʻO nā masks nā lole ulana ʻole, nā lole ulana ʻole i kūʻē i nā lole ulana, a ua haku ʻia i nā ʻāpana kuhikuhi a i ʻole kūlike ʻole.

ʻO nā masks lapaʻau he mau hale nunui-papa, i kapa ʻia he mau ʻano SMS (2 S a me 1 M mau papa). I kēia manawa, ʻo ka helu kiʻekiʻe loa o nā papa ma Kina he 5, ʻo ia hoʻi SMMMS (2 S mau papa a 3 M mau papa).

He aha ka SMS?

Ma aneʻi, kū ʻo S i ka papa Spunbond. He mānoanoa ke anawaena o ke olonā, ma kahi o 20 microns (m). ʻO ka hana nui o nā papa 2 S Spunbond ke kākoʻo ʻana i ka hanana lole ulana ʻole āpau, ʻaʻohe hopena maikaʻi i ka pale. ʻO ka ʻāpana nui o ka pale maka ka pale pale a i ʻole Meltblown papa M (Meltblown papa). He lahilahi ke anawaena o ka papa hoʻoheheʻe hoʻoheheʻe ʻia, ma kahi o 2 microns (M), no laila he ʻumi wale nō ia o ke anawaena o ka papa spunbonding, kahi mea nui i ka pale ʻana i ka bacteria a me ke komo ʻana o ke koko.

Hoʻohana pinepine nā masks lapaʻau maʻamau i ka lole hoʻoheheʻe e kaupaona ana he 20 gram, hoʻohana nā masks kīʻaha N95 i ka lole hoʻoheheʻe e kaupaona ana he 40 gram a ʻoi paha.

Wahi a nā helu helu o ka ʻoihana ʻoihana ʻoihana ʻenehana ʻo Kina, ma ka hopena o ka makahiki 2018, aia he 1,477 laina laina hana spunbonded, 65 ʻoi aku ka nui o kēlā me ka makahiki i hala, me ka hoʻonui makahiki o 4.6%, a ʻo ia hoʻi, PP Hoʻonui ʻia ka laina hana non-woven spunbonded e 3.38%, laina laina hana SMS e aneane 13%, a me PET laina spunbonded non-woven i hana ʻia e 9.32%. Ua hoʻonui ʻia ka helu o nā ʻoihana me nā huahana makahiki i ʻoi aku ma mua o 50,000 tone mai 2017. ke wikiwiki nei i kā lākou ulu ʻana i ka pālākiō, hoʻonui a me ka hopena kiʻekiʻe e kū i ka noi mākeke o ka hoʻomaikaʻi huahana a me ka hoʻomaikaʻi ʻana ʻenehana.

Mai ka makahiki 2018, ua hoʻomohala nā ʻoihana ʻohana he nui i kā lākou huahana i ke ala o ka māmā, lahilahi a me ke kiʻekiʻe o ka hana, a loaʻa nā hopena maikaʻi. SSMMS spunbonded / hoʻoheheʻe ʻia shotcreting hui hiʻina 600m / min a ma luna o ka wikiwiki wikiwiki e hoʻomau i ka puka o nā huahana māmā paʻa.

No hea mai ka lole lole ulana SMS?

Hana nui ʻia nā lole SMS ʻaʻole i ulana ʻia mai polypropylene PP (me nā ʻano bacteriostatic kūlohelohe a me ka hydrophobicity), a hiki ke anawaena o nā olonā i 0.5-10 mau microns. ʻO kēia mau fibre ultrafine me ka capillarity kū hoʻokahi e hoʻonui ai i ka nui a me ka ʻāpana o nā olonā i kēlā me kēia ʻāpana, no laila e hana ana i nā lole hoʻoheheʻe i hoʻoheheʻe ʻia nā ea maikaʻi, e hoʻolilo iā lākou i mea mask mask maikaʻi loa.

At present, there are three main processes for manufacturing SMS products (SMS non-woven fabric) : "one-step process", "two-step process" and "one-and-a-half step process".

One-step features is the use of raw materials section of this process, using two spun-bonded, melt-blown technology, direct spinning raw material after melting into the nets, as long as reasonable arrangement of different process of spinning systems engineering, and can make the products with different structure, each layer fabric laminated composite, is usually with a hot rolling mill consolidation into cloth."One-step method" is characterized by melting directly spinning into a net, the state of each spinning system can be independently adjusted, the production process of strong control, good health conditions, high speed, can adjust the proportion of each layer of fiber net, can produce SMS type products of various specifications, is the mainstream technology today.

Two-step process: When using the two-step process to produce SMS products, the finished products of spunbonded cloth and melt-sprayed cloth are unrolled in a certain order, and then laminated in a sequence, and then consolidated with a hot mill, and compounded into SMS products.The two-step method is characterized by simple equipment and low cost.In fact, the "two-step" process is the widely used lamination composite technology, but also can be composite of other materials, with different other materials, and with different methods, such as ultrasonic, hot melt adhesive three layers of materials together.

One-and-a-half step method: in two-step method, it is also possible to replace the molten spraying cloth product with the molten spraying layer fiber net produced in the field, thus derived the so-called "one-half step method" composite process.The spunbonded cloth is used as the bottom layer and the surface layer by two unwinding devices, and the melt spraying fiber net of the middle layer is directly spun into a net by the melt spraying system, laid on the bottom layer of the spunbonded cloth, and then covered with the upper layer of the spunbonded cloth, it is better to use a hot mill consolidated into SMS products.
