SMS isiri-yakarukwa jira kubva kupi | JINHAOCHENG

Masiki ndeemachira asina kurukwa, ayo ari machira asina kurukwa zvinopesana nemicheka yemachira, uye anoumbwa neshinda inonongedza kana yakasarudzika.

Masiki ekurapa anowanzo kuve akawanda-akapetwa masisitimu, anowanzo kunzi masisitimu eSMS (2 S uye 1 M masendimita) Parizvino, huwandu hwakanyanya hwezvikamu muChina i5, zvinoti SMMMS (2 S masheya uye matatu M akaturikidzana).

Chii chinonzi SMS?

Pano, S inomirira Spunbond rukoko. Iyo dhayamita yeiyo fiber yakaenzana, ingangoita makumi maviri emamirioni (m). Basa hombe rezvikamu zve 2 S Spunbond ndere kutsigira iyo isina-yakarukwa machira machira, ayo asina simba rakakura padanho. Chikamu chakakosha cheiyo maski ndiyo yekudzivirira nhete kana Meltblown denderedzwa M (Meltblown layer). Iyo dhayamita yesimbi yakanyungudutswa yakasviba yakatetepa, anenge ma2 microns (M), saka inongova chegumi chete chehupamhi hwespunbonding layer, inoita basa rakakosha mukudzivirira mabhakitiriya uye kupinda kweropa.

General masiki ekurapa anowanzo shandisa melt jira rehuremu rinorema magiramu makumi maviri, N95 mukombe masiki anoshandisa melt spray jira rinorema magiramu makumi mana kana kudarika.

Zvinoenderana nehuwandu hweChina Industrial Textile Industry Association, panopera gore ra2018, pane 1,477 yekumba spunbonded yekugadzira mitsara, 65 kupfuura iyo yegore rapfuura, iine gore-gore-gore kuwedzera kwe4,6%, pakati payo, PP spunbonded isiri-yakarukwa yekugadzira tambo inowedzerwa ne3.3%, SMS inoumbwa nemutsetse wekugadzira mutsara neinosvika 13%, uye PET yakarukwa isiri-rakarukwa yekugadzira mutsara ne9.32% .Iyo nhamba yemakambani ane gore pagore anoburitsa anodarika zviuru makumi mashanu ematani akawedzerawo kubva muna 2017.Spunbonded Enterprises vari kukurumidzisa kusimudzira kwavo kusvika pachikero, kuwedzera uye kukwirira-kumagumo kusangana nemusika wekuda kwekuvandudza zvigadzirwa uye kusimudzira tekinoroji.

Kubva 2018, mazhinji emabhizinesi epamba akavandudza zvigadzirwa zvavo munzira yekureruka, yakatetepa uye yepamusoro kuita, uye vakawana mhedzisiro.SMSM spunbonded / yakanyungudutswa shotcreting inoumbwa nemaitiro 600m / min kana pamusoro pekumhanyisa kumhanya mashandiro; Anenge gumi magiramu pa square mita yakanyanya kupfava. mwenje yakagadzikana mhando zvigadzirwa zvinoramba zvichibuda.

Ko jira reSMS risina kurukwa rinobvepi?

SMS isina-yakarukwa machira anonyanya kugadzirwa kubva kune polypropylene PP (ine yakasikwa bacteriostatic zvivakwa uye hydrophobicity), uye hupamhi hweiyo tambo inogona kusvika 0.5-10 microns. Iyi tambo ye ultrafine ine yakasarudzika capillarity inowedzera huwandu uye pamusoro penzvimbo dzenzvimbo panzvimbo yeyuniti, nokudaro ichigadzira machira akanyungudika ane mweya wakanaka wekusefa zvivakwa, zvichivaita iwo masiki akanaka ezvinhu.

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.
