Jira rakanyunguduka riri mumasiki rakagadzirwa nei? JINHAOCHENG

Mumakore maviri apfuura, hutachiona hutsva hwekorona huri kuramba huchipararira uye denda idzva rekorona rave guru kune dzimwe nyika. Isu vanhuwo zvavo tinofanira kuzvidzivirira zvakanyanya, kungwarira kupfeka masiki (masiki anoraswa, masiki ekurapa anoraswa kanaMasiki eKN95, masks eN95) uye teererai daro revanhu, uye tarisai izvi. Kuti muzive zvekudzivirira, munogona kutarisa nzira dzakanakisisa dzeChina dzekudzivirira denda. Nenzira iyi, hutano hwedu, kusanganisira mhuri yenyu, shamwari, vaunoshanda navo, nezvimwewo, hunogona kudzivirira hutachiona uye kunakidzwa nehupenyu.

Saka, nhasi, pamwe chete naJin Haocheng, mugadziri wejira rakaputirwa nemhepo (zvinhu zvemasiki), ngatidzidzei kuti zvinhu zvejira rakaputirwa nemhepomumasiki inogadzirwa.
　
Jira rakanyunguduka rinogadzirwa zvakanyanya ne polypropylene, uye dhayamita yefiber inogona kusvika 1 kusvika 5 microns. Kune ma voids akawanda, chimiro chakapfava, uye kugona kwakanaka kwekudzivirira makwinya. Aya ma fibers akapfava kwazvo ane chimiro chakasiyana che capillary anowedzera huwandu nenzvimbo yepamusoro ye fibers pa unit area, zvekutijira rakaputirwa nemhepoIne kupfapfaidza kwakanaka, kudzivirira, kudzivirira kupisa uye kunyudza mafuta. . Inogona kushandiswa muminda yemhepo, zvinhu zvinosefa mvura, zvinhu zvinopatsanura, zvinhu zvinonyudza, masiki, zvinhu zvinonyudza kupisa, zvinhu zvinonyudza mafuta uye machira ekupukuta.

Munhu wese anoziva kuti masiki ekurapa ane chikamu chejira rakaputirwa nemhepo, saka chii chiri muchinhu ichochochifukidzo chekurapajira rakanyungudika rakagadzirwa nejira rakanyungudika?

Jira rinoputika rakashandiswa mumasiki rinogadzirwa nezvinhu zvepolypropylene, uye jira rinoputika rakaputika rakaitwawo nezvinhu zvepolypropylene zvinonzi high-melt fat fiber. Imhando yejira remagetsi rakapfava re ultra-fine, rinogona kushandisa magetsi asingachinji kutora mavhairasi, guruva, madonhwe, ichi ndicho chikonzero chakakosha nei masks dzichigona kusefa mavhairasi. Masks ekurapa anowanzo shandisa chimiro che multi-layer, chinonzi chimiro cheSMS: single spunbond layer (S) kumativi ese. Pane layer imwe chete kana multiple meltblown layers (M) pakati. Chinhu chakanakisa che layer rinoputika ijira rinoputika. Ndiro chinhu chikuru chekusefa mavhairasi emamasiki, uye jira repakati reM layer-meltblown non-woven. Kutaura zvazviri, aya matatu machira ese asiri akarukwa, uye zvinhu zvisina kugadzirwa zvese ipolypropylene, asi maitiro ekugadzira akasiyana. Pakati pawo, dhayamita yefiber ye spun-bonded layer kumativi emukati nekunze yakakora, inenge 20 microns; Upamhi hwefiber inonyungudika iri pakati pechikamu i2 microns chete, iyo yakagadzirwa nepolypropylene inonzi high-melt fat fiber. Haina kusimba uye haigone kugezwa nemvura kana kupfapfaidzwa nedoro. Kunyangwe yakanyorova uye yaoma, inokuvadza fiber tissue uye inokonzeresa maburi. Kana mavhairasi akapinda nepaburi, mask inorasikirwa nekudzivirira kwayo.

Nekuda kwedambudziko guru redenda riripo parizvino, mamasiki ave chinhu chakakosha muhupenyu hwedu hwekufamba. Ngatinzwisisei kuti sei mamasiki achigona kudzivirira mavhairasi? Chekutanga, huwandu hwecoronavirus hunosvika 80 ～120nm, nekuti inowanzo sungirirwa mumvura yemuviri uye inopfapfaidzwa. , Saka kazhinji yakakura kupfuura 0.1um (0.1 micron (um) = 100 nanometers (nm)). Jira rakanyungudika rinoshandisa polypropylene sechinhu chikuru chekugadzira, uye dhayamita yefiber inogona kusvika 0.5-10um. Kana iri hutachiona hwakabatana nemvura yemuviri, inogona kusvinwa.

Kubva musumo iri pamusoro apa, unoziva zvakawanda nezvemasiki here?

Kuti muwane ruzivo rwehunyanzvi uye mazano pamusoro peJira Risina Kurukwa Rakanyungudika, Chigadzirwa Chakapedzwa Chisina Kurukwa, Jira Risina Kurukwa reSpunlace, Sefa Jira Risina Kurukwa, Yakaboorwa neFelt-Tsinde Isina Kurukwa, munogamuchirwa kuti mubate Jin Haocheng Non-woven Fabric. Tichaita zvese zvatinogona kuti tikushandirei.
