SMS lamba tsy tenona izay | JINHAOCHENG

Ny sarontava dia lamba tsy tenona, izay lamba tsy tenona mifanohitra amin'ny lamba lamba, ary misy kofehin-tondro avy na tendro sendra.

Ny sarontava ara-pitsaboana dia mazàna rafitra maro sosona, antsoina matetika hoe firafitra SMS (sosona 2 S sy 1 M). Amin'izao fotoana izao, ny isan'ireo sosona avo indrindra ao Shina dia 5, dia ny SMMMS (sosona 2 S sy ny sosona 3 M).

Inona no atao hoe SMS?

Eto, S dia mijoro ho an'ny sosona Spunbond. Somary matevina ny savaivon'ny fibre, manodidina ny 20 microns (m). Ny tena asan'ny sosona 2 S Spunbond dia ny fanohanana ny firafitry ny lamba tsy misy tenona iray manontolo, izay tsy misy akony lehibe amin'ny sakana. Ny ampahany manan-danja indrindra amin'ny saron-tava dia ny sosona sakana na sosona Meltblown M (sosona Meltblown). Ny savaivon'ilay soson-tsifotra narendrika dia manify, manodidina ny 2 microns (M), ka ampahafolon'ny savaivon'ny sosona spunbonding ihany io, izay mitana andraikitra lehibe amin'ny fisorohana ny bakteria sy ny fidiran'ny ra.

Ny saron-tava amin'ny fitsaboana ankapobeny dia matetika mampiasa lamba famaohana ahetsiketsika milanja 20 grama, saron-tava N95 kaopy mampiasa lamba famafazana milanja 40 grama na mihoatra.

Araka ny antontan'isan'ny Fikambanan'ny Indostrian'ny indostrialy China, tamin'ny faran'ny taona 2018, dia misy 1.474 andalana famokarana an-trano, 65 mihoatra ny an'ny taona teo aloha, miaraka amin'ny fisondrotana 4,6% isan-taona, isan'izany ny PP ny tsipika famokarana tsy tenona spunbonded dia nitombo 3,38%, ny tsipika famokarana kompania SMS efa ho 13%, ary ny tsipika famokarana tsy tenona PET dia 9,32%. Ny isan'ny orinasa manana vokatra isan-taona mihoatra ny 50 000 taonina dia nitombo hatramin'ny 2017. manafaingana ny fivoarany mankany amin'ny ambaratonga, ny fanamafisana ary ny avo lenta mba hamaliana ny filan'ny tsena fanavaozana ny vokatra sy ny fanavaozana ny teknolojia.

Hatramin'ny taona 2018 dia maro ny orinasa an-trano no namolavola ny vokariny amin'ny làlan-kaleha maivana kokoa sy mihamitombo ary nahitana vokatra tsara. Ireo vokatra kalitao maivana dia mitohy mipoitra.

Avy aiza ny lamba tsy tenona SMS?

Ny lamba tsy tenona amin'ny SMS dia vita indrindra amin'ny polypropylene PP (miaraka amin'ny toetra voajanahary voajanahary sy hydrophobicity), ary ny savaivon'ny fibre dia mety hahatratra 0,5-10 microns. Ireo kofehin-drakitra ultrafine misy capillarity tsy manam-paharoa dia mampitombo ny habeny sy ny velaran'ny velaran-tariby isam-paritra, ka mahatonga ireo lamba voarendrika ireo dia manana toetra fanivanana rivotra, ka mahatonga azy ireo ho maska ​​tsara.

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.
