Sezvo kunze kunowedzera kudziya uye tembiricha inokwira, zvipfeko zvinopera uye zvinopera zvishoma. Panguva ino, kufema-kugona kwezvipfeko kunonyanya kukosha! Chidimbu chechipfeko chine kufema kwakanaka-kugona kuburitsa ziya kubva mumuviri, saka iyokufema-kugona kwejirayakabatana zvakananga nekunyaradza kwejira.
Kushandiswa kwekufema-kugona muindasitiri yemachira
Indasitiri yekupfeka: Kugona kufema ndechimwe chezviratidzo zvakakosha zvekuongorora kunyaradza kwemachira. Kunyanya kana uchigadzira zvipfeko zvekunze zvemitambo, shangu dzemitambo uye zvimwe zvigadzirwa, zvinodikanwa kuti uone kana vachigona kupa kugona kufema kwakanaka kuburikidza nekufema kugona kuyedza kuti uwane hunyoro uye dikita. , Ramba wakaoma maitiro.
Micheka yekumba: zvigadzirwa zvakaita semubhedha, maketeni, zvivharo zvefenicha, nezvimwewo. Kuongororwa kwemhepo kunogona kushandiswa kuona kupinza kwemhepo yezvigadzirwa izvi uye wobva waongorora kugarika kwavo uye kushanda.
Zvekurapa: Zvipfeko zvekurapa zvakaita semajasi ekuvhiya nemasiki zvinoda kuve nekugona kufema kwakanaka kuona kuti vashandi vekurapa vanogona kuramba vakagadzikana munzvimbo yekushanda kwenguva refu. Kuburikidza nekufema kugona kuyedzwa, iyo gasi yekuchinjana kuita kwechigadzirwa inogona kutsunga kudzivirira kutapukira kwebhakitiriya nehutachiona.
Midziyo yemitambo: Mimwe midziyo yemitambo yakadai seshangu dzemitambo, ngowani dzemitambo, nezvimwe zvichashandisawo kufema kugona kuyedza kuti ive nechokwadi chekuita kwavo kutenderera kwemhepo.
Zvishandiso zvekufema-kugona mune mamwe maindasitiri
Zvigadzirwa zvemukati zvemotokari zvemukati: Sarudza kupindirana kwemhepo uye kuramba kwemhepo kwemidziyo yemukati yemotokari (senge polyurethane, PVC, dehwe, machira, machira asiri akarukwa, nezvimwewo).
Zvivako zvekuvaka: Sarudza kupindira kwemhepo kwezvinhu zvekuvaka (zvakadai sedombo, kongiri, nezvimwewo) kuongorora kugona kwavo kukanganisa hutano hwemhepo mukati mechivako.
Packaging materials: Mazhinji akakosha ekurongedza zvinhu (sekutsva-kuchengeta kurongedza, nezvimwewo) zvinoda kuve nehumwe dhigirii rekupenya kwemhepo kuve nechokwadi chemhando yemukati yekurongedza.
Zvigadzirwa zvemagetsi: Zvimwe zvikamu zvezvigadzirwa zvemagetsi zvinoda kuve nekufema kwakanaka kuti ive nechokwadi chekushanda kwakajairika kwemidziyo yemagetsi.
Kuenzanisa nzira dzakasiyana dzekuyedza dzekufema-kugona
Ikozvino, kune akawanda mazinga uye nzira dzejira rekufema-kugona kuyedza.

Pakati pavo, nzira mbiri dzakajairika, ISO 9237 uye ASTM D737, dzinoshandiswa zvakanyanya. GB/T 5453-1997 chiyero ichi chinoshanda kune akasiyana machira emucheka, anosanganisira machira emaindasitiri, machira asiri akarukwa uye zvimwe zvinofema machira. Munguva yekuyedzwa, machira ezvipfeko uye machira eindasitiri akasiyaniswa zvine hungwaru kuburikidza neakasiyana madonhwe ekumanikidza. Kudonhedzwa kwekumanikidzwa kwemachira embatya kwaive 100Pa, uye kudonha kwekumanikidzwa kwemachira eindasitiri kwaive 200Pa. MuGB/T5453-1985 "Fabric Breath-ability Test Methods", iyo mhepo permeability (zvichireva huwandu hwemhepo inoyerera nepakati pechikamu chejira pane imwe nguva yeyuniti pasi pekudzvanywa kwakatsanangurwa mativi ese ejira) inoshandiswa kuyera kupera kwemhepo kwejira. Iyo yakadzokororwa yakajairwa GB / T 5453-1997 inoshandisa mhepo permeability (zvichireva chiyero chekuyerera kwemhepo yakatwasuka ichipfuura nesainzi pasi penzvimbo yakatsanangurwa yemuenzaniso, kudonhedza kudonha uye nguva mamiriro) kuratidza kupenya kwemhepo kwejira.
ASTM D737 inosiyana neiyo iri pamusoro apa maererano nehuwandu hwemashandisirwo, tembiricha uye humidity, nzvimbo yekuyedza, mutsauko wekumanikidza, nezvimwewo. Tichifunga nezve mamiriro chaiwo ekutengesa uye kutengesa machira, zvakarongwa kushandisa masampuli akasiyana kuenzanisa uye kukurukura chaiyo tembiricha uye hunyoro, nzvimbo yekuyedza, kudzvanywa musiyano uye mamwe mamiriro e ISO 9237 uye ASTM D737, sarudza iyo inoshanda uye inomiririra mamiriro, uye gadza yakakodzera Indasitiri zviyero zvekupinza uye kunze kwenyika kutengeserana.
Muedzo mhedzisiro kuenzanisa
Mhedzisiro yekufema-kugona mhedzisiro yakanyatsoenderana nenzira yekuyedza inoshandiswa. Pakati pemigumisiro yekuedza yakawanikwa uchishandisa nzira ina dzakasiyana dzekuedza nzira: ISO 9237, GB / T 5453, ASTM D 737 uye JIS L 1096: mhepo inopera yakaedzwa maererano neGB / T 5453 uye ISO 9237 yakafanana; maererano neGB/T5453 (ISO 9237) ) Kupinda kwemhepo kwakaedzwa ndiko kuduku; iyo mhepo permeability yakaedzwa maererano neJIS L1096 ndiyo yakakura; iyo mhepo permeability yakaedzwa maererano neASTM D737 iri pakati. Apo nzvimbo yekuedza inoramba isina kuchinjwa, kupindira kwemhepo kunowedzera sezvo kudonha kwemhepo kunowedzera, iyo inofananidzwa nekudonha kwemhepo kunowedzera kakawanda. Muchidimbu, chete nekusarudza nzira dzakakodzera dzekuyedza zvinoenderana nehunhu hwechigadzirwa ndipo panogona kunyatsoongororwa kufema kwemachira.
Tsananguro yakadzama yematanho ebvunzo (kutora GB/T 24218-15 semuenzaniso)
Sampling inotemerwa zvichibva pane zvigadzirwa zviyero kana kubvunzana nemapato akakodzera. Pamidziyo yekuyedza iyo inogona kuyedza zvakananga machira akakura-asina kuruka, angangoita zvikamu zvishanu zvejira guru risingarukwe rinogona kusarudzwa zvisina tsarukano semasamples ekuedzwa; yemidziyo yekuyedza isingakwanise kuyedza saizi yakakura, mold yekucheka kana template inogona kushandiswa (Cheka angangoita mashanu masampuli e100mmX100 mm saizi).
Isa sampuli kubva kune yakajairwa nharaunda munzvimbo yakajairwa yemhepo inoenderana neGB/T6529 uye gadzirisa humidity kuti ienzane.
Bata kumucheto kwemuenzaniso kudzivirira kushandura mamiriro echisikigo enzvimbo yekuedza isina kuruka.
Isa mufananidzo pamusoro webvunzo uye wougadzirisa ne clamping system kudzivirira kukanganisa kwemuenzaniso kana kumucheto kwegasi kuvuza panguva yebvunzo. Kana paine mutsauko mukupindira kwemhepo pakati pemberi uye kumashure mativi emuenzaniso, chikamu chebvunzo chinofanira kucherechedzwa mumushumo webvunzo. Kune zvienzaniso zvakavharwa, isa mufananidzo nedivi rakavharidzirwa pasi (kurutivi rwekumanikidzwa kwakaderera) kudzivirira kumucheto kwegasi kubuda.
Batidza pombi yevacuum uye gadzirisa mwero wekuyerera kwemhepo kusvika mutsauko unodiwa wasvika, kureva, 100Pa, 125Pa kana 200Pa. Pane zvimwe zviridzwa zvitsva, kukosha kwekumanikidza kwekuyedza kunosarudzirwa nedigital, uye musiyano wekumanikidzwa pamativi ese echiyero chekuyera chinoratidzwa nedhijitari mune yakasarudzwa test unit kuti ifambise kuverenga kwakananga.
Kana chiyero chekumanikidza chikashandiswa, mirira kusvikira kukosha kwesimba kunodiwa kwagadzikana uye woverenga kukosha kwemhepo kupinza mumalita paskweya centimita masekonzi [L/(cm·s)].
