Sei masks achidzivirira kupararira kwehutachiona?

Chinhu rudzii?

Isu tinowanzo taura kuti masikisi anogadzirwa nemachira asina kurukwa.Micheka isiri-yakarukwa micheka isina kurukwa, inopesana nemicheka yakarukwa, iyo inogadzirwa neyakatariswa kana isina kurongeka.
Kana zvasvika kumasiki, iyo mbishi zvinhu ndeyePolypropylene (PP).Masks anoraswa kazhinji ane multilayered Polypropylene.Zita reChirungu: Polypropylene, PP kwenguva pfupi, haina ruvara, isina kunhuhwirira, isiri-chepfu, inoshanduka-shanduka yakasimba chinhu, inova musanganiswa wepolymer wakaumbwa nepolymerization yepropylene.Polypropylene inoshandiswa zvakanyanya mukugadzira zvigadzirwa zvefiber zvakadai sembatya nemagumbeze, midziyo yezvokurapa, motokari, mabhasikoro, zvidimbu, pombi dzekutakura uye midziyo yemakemikari, pamwe chete nekuputirwa kwezvokudya nemishonga.
Iro jira risiri rakarukwa rinogadzirwa neakakosha zvinhu zvepolypropylene risingarukwe jira rinogona kushandiswa kuraswa hembe dzekushanda, mashiti, masks, zvivharo, mvura yekunyudza pads uye. zvimwe zvekurapa nezveutano.

Masks anozivikanwa kuve ane zvinodzivirira painoveli coronavirus anonyanya kusanganisira anoraswa ekudzivirira masks uye N95 masks.Iyo huru sefa zvinhu zveaya masiki maviri akanaka kwazvo, electrostatic filter lining - yakanyunguduka-yakavhuvhuta isina-yakarukwa jira.Mucheka wakanyungudutswa usiri wakarukwa unonyanya kugadzirwa nepolypropylene, imhando yeultrafine electrostatic fiber jira, inogona kubata huruva.
Madonhwe ine utachiona hwemabayo pedyo nejira rakanyunguduka risiri rakarukwa rinenge riri electrostatic adsorption pamusoro pejira risiri rakarukwa, haringapfuuri, uyu ndiwo musimboti weizvi. utachiona hwekuzviparadzanisa nevamwe.Mushure mekunge guruva rabatwa neiyo ultrafine electrostatic fiber, zvakaoma kwazvo kupatsanurwa nekuchenesa, uye kugeza kunoparadza kugona kuunganidza guruva remagetsi, saka iyi mask inogona kushandiswa kamwe chete.

Masks ekudzivirira anoraswa anowanzo kugadzirwa nemateru matatu ejira risiri rakarukwa.Izvo zvinhu zvakarukwa jira risiri rakarukwa + jira rakanyungudutswa risiri rakarukwa + jira rakarukwa risiri rakarukwa.
Zvikamu zvinoverengeka zvemasiki hazvina kutaurwa muyero yenyika GB/T 32610 yemasiki.Kune masiki ekurapa, panofanirwa kuve neanosvika matatu akaturikidzana, ayo anonzi SMS (2 akaturikidzana eS uye 1 layer yeM).
Nhamba yepamusoro-soro yezvikamu muChina ikozvino 5 layers, iyo inonzi SMMMS (2 zvidimbu zveS uye 3 zvikamu zveM).Pano iyo S inomiririra iyo Spunbond layer (Spunbond), fiber dhayamita yayo yakati gobvu, anenge 20 microns (μm), basa guru rezvikamu zviviri zveS Spunbond ndere kutsigira iyo yose isiri-yakarukwa machira maumbirwo, uye haina zvakawanda mhedzisiro pane chipingamupinyi.Chinhu chinonyanya kukosha mukati me mask ndiyo inovharira layer kana Meltblown layer M (Meltblown).
Iyo fiber dhayamita yeMeltblown layer yakanaka, ingangoita 2 microns (μm), iyo inoita basa rakakosha mukudzivirira bhakitiriya neropa kupinda. mariri.Kana S spun-bonded layers yakawandisa, mask yakaoma, uye yekupfapfaidza layer M yakawandisa, kufema kwakaoma, saka kubva pakureruka kwekufema masks kusvika pakuongorora mhedzisiro yekuzviparadzanisa nemasiki, kufema zvakanyanya. yakaoma, inovharira mhedzisiro iri nani, asi, kana M layer mufirimu, isingafeme zvakasununguka, hutachiona hunogurwa, asi vanhu havagone kufema.Iyo N95 inonyatso 5-layer mask yakagadzirwa kubva ku polypropylene nonwoven SMMMS inosefa anosvika makumi mapfumbamwe neshanu muzana ezvimedu zvakanaka.

Naizvozvo, takaona kuti masiki anogona kunyatsozvitsaura hutachiona anofanirwa kugadzirwa nezvinhu zvakati, uye hazvisi zvese zvinhu zvakakodzera masks.
Sekupedzisira, isu ORIENTMED tinovimba nemoyo wese kuti wese anogona kuzvichengeta wakachengeteka uye uine hutano.
