Nekuenderera mberi kupararira kwedenda repasi rose, kudiwa kwezvinhu zvekudzivirira denda munyika dzepasirese kuri kuwedzera. Kambani yedu inodyidzana nemakambani makuru emudzimba kuzadzisa zvinodiwa mukudzivirira denda redzimba, uye panguva imwecheteyo, tiri kuedza nepatinogona napo kuti tipe zvinhu zvinodikanwa nekukurumidza kurwira pasi rose kurwisa covid-19. Mamiriro eCovid-19 muChina akadzorwa zvakanyanya, uye mitengo yemachira asina kurukwa nemachira akanyunguduka iri kudonha zvakanyanya, izvo zvinogona kuchengetedza mutengo wakawanda. Panguva imwecheteyo, tinogona kuve nechokwadi chekuvandudzwa kwemhando yechigadzirwa, kuitira kuti vatengi vagone kutenga zvigadzirwa zviri nani pamutengo wakanakisa, uye kuziva vatengi vanoramba vachidzoka mirairo.Tinopa mhando yakanaka uye mutengo, kugamuchirwa kune vatengi vepasirese kuti vabvunze.
Melt-blown nonwoven inoshandisa polypropylene sechinhu chikuru mbishi. Iyo fiber dhayamita inogona kusvika 1to5um. Kune akawanda voids, fluffy chimiro uye yakanaka kupeta kuramba. Iyo Melt-blown nonwoven ine yakasarudzika capillary chimiro iyo inowedzera nhamba uye pamusoro penzvimbo yefiber panzvimbo yeyuniti, kuitira kuti iyo inonyunguduka-inoputika nonwoven ine yakanaka kusefa, kudzivirira, kupisa kupisa uye kunyura kwemafuta.
Melt-blown nonwoven ndiyo musimboti wezvinhu zvemask. Melt blown jira rine simba rekusefa kuita, mabhenefiti akatanhamara mukusefa, becteria kuramba, adsorption, nezvimwe.
KUGADZIRA NZIRA
Kuyerera kwemhepo inopisa inomhanya-mhanya kunokwevera rukova rwakatetepa rwepolymer yakanyungudika yakanyungudutswa kubva kune inofa orifice yefa iyo inoumba akanyanya-akatsetseka fibers. Zvadaro, tinozviunganidza pachidzitiro chakakomberedzwa kana roller uye panguva imwe chete tichizvisunga kuti zviite Melt-blown nonwoven fabric.
Meltblown process
Polypropylene PP zvimedu → nyungudutsa extrusion → metering pombi → nyungudika-inofefeterwa kufa musanganiswa wemusoro → nyungudutsa zvakanaka kuyerera kutambanudza → kutonhora → yekugamuchira mudziyo → electrostatic electret → yekuchekesa muchina
Meltblown midziyo
Midziyo mikuru: muchina wekudyisa, screw extruder, metering pump, melt-blown die head assembly, air compressor, air heater, receiveing device, electrostatic electret, winding device.
Mutsetse wekugadzira wakashongedzerwa neakanakisa abrasive maturusi, Sanxin electrostatic electret, yemhando yepamusoro yakanyungudutswa zvinhu zveJinfa tekinoroji, nerabhoritari yehunyanzvi nemidziyo yekuongorora inotengeswa kunze kwenyika kuti ive nechokwadi chekugadzirwa kwejira remhando yepamusoro rakanyungudutswa. Kunda kudzikira kweiyo static electret uye uve nechokwadi chenguva refu electret yemucheka wakanyunguduka.
Akawanda maitiro emucheka wakanyunguduka: zvinoenderana nezviyero zveGB / T32610-2016, GB / 19083-2010, YY / T0969-2013 (maski yekurapa inoraswa), YY / T0469-2011 (mask yekuvhiya yekurapa), nezvimwe, zvinoenderana nezvinodiwa zvevatengi zvakare.

Kufefetera zvakanaka ndeimwe yeakakosha kuita kwemasiki. Masikisi akasiyana ane basa rekusefa huruva, magasi ane chepfu uye utachiona. Naizvozvo, iyo nhanho yekusefa inonyatso ratidza kunaka kwemask.
