Girazi faibha kupisa kuvharisa moto kuvharisa moto retardant risiri-alkali jira
Girazi faibha (yaimbozivikanwa sekuti: girazi faibha) imhando yezvisiri zvesimbi zvemukati zvine mashandiro akanaka.Iine mabhenefiti akasiyana-siyana, akadai sekudzivirira kwakanaka, kupisa kwakasimba kwekudzivirira, kunaka kwekusagadzikana uye kusimba kwemagetsi epamusoro, asi zvisungo zvayo ndeye brittleness uye kusapfeka kusakara.Girazi faibha rinowanzo shandiswa sezvinhu zvekusimbisa muzvinhu zvakaumbwa, zvemagetsi zvekudzivirira zvemagetsi uye zvinopisa zvekudzivirira, magetsi roadbed board uye mamwe minda yehupfumi hwenyika.
1. Inoshandiswa kune yakaderera tembiricha -196 ℃.yakakwirira tembiricha 300 ℃ pakati.nekupikisa kwemamiriro ekunze.
2. Bon-adhesive.hazvisi nyore kunamatira kune chero chinhu.
3. Chemical corrosion resistance.asidhi yakasimba.alkali.aqua regia uye zvakasiyana-siyana zve organic solvent corrosion.
4. Low friction coefficient.ndiyo yakanakisa sarudzo yemafuta-isina self-lubrication.
5. Chiedza chekufambisa kwe6 ~ 13%.
6. Nekushanda kwepamusoro kwekudzivirira.anti-UV.anti-static.
7. Kusimba kwepamusoro.Iine maitiro akanaka emagetsi.
8. Kuramba zvinodhaka.
Girazi faibha jira rinoshandiswa kunamira nemaoko mukuita, girazi faibha yakasimbisa zvinhu gidhi jira rinonyanya muhull, tangi yekuchengetera, inotonhorera shongwe, ngarava, mota, tangi, chivakwa chekuvaka.Girazi fiber jira muindasitiri inonyanya kushandiswa kune: kupisa kupisa, kudzivirira moto, kudzoreredza moto.Nyaya yacho inotora kupisa kwakawanda kana yapiswa nemurazvo uye inogona kudzivirira murazvo kuti usapfuure, ichiteya mweya.
1. Maererano nekuumbwa: kunyanya alkali, alkali, high alkali (ndeyekuronga kuumbwa kwealkali metal oxide mugirazi fiber), hongu, kunewo kupatsanurwa nezvimwe zvikamu, asi zvakawanda zvakasiyana-siyana, kwete rondedzero.
2. Maererano nekugadzirwa kwekugadzira: crucible drawing uye pool kiln drawing.
3. Maererano nemhando dzakasiyana-siyana: kune mutsara wakaparadzaniswa, tambo yakananga, jet yarn, nezvimwewo.
Uye zvakare, zvinoenderana neiyo imwechete fiber dhayamita, TEX nhamba, twist, inopinda mumiririri mhando kusiyanisa.
Kurongeka kwegirazi fiber jira uye shinda yefiber yakafanana, mukuwedzera kune iri pamusoro, inosanganisirawo: kuruka, uremu hwegiramu, amplitude, nezvimwe.
Girazi fiber jira uye girazi zvinhu musiyano
Girazi faibha jira uye girazi main zvinhu musiyano hauna kukura, kunyanya nekuda kwekugadzirwa kwezvinhu zvinodiwa zvakasiyana, saka kune mimwe misiyano mufomula.Iyo silica yemukati yegirazi regirazi inenge 70-75%, uye silica yemukati yegirazi fiber kazhinji iri pasi pe60%.
Girazi is inorganic material mushure mekunyunguduka kwekushisa kwepamusoro (pamusoro pe800 degrees, girazi repamba rinowanzonyungudutswa pa1100 degrees)., pasi pekunyorovesa tembiricha, hapana shanduko yemakemikari ichaitika.Pamusoro pekushisa kwenzvimbo yekunyorova, inongonyorovesa, inonyunguduka kana kuora, pasina kupisa.
Girazi faibha jira ndiro girazi rinodhonzwa muwaya yakanaka kwazvo yegirazi, panguva ino waya yegirazi ine kupfava kwakanaka kwazvo.Girazi filament inorukwa kuita shinda yobva yapfuura nemuchirako kugadzira jira refiberglass.Nekuti iyo girazi filament yakanaka kwazvo, iyo nzvimbo yepasi pauniti misa yakakura kwazvo, saka tembiricha yekudzivirira inoderedzwa.Kungofanana nekenduru rinogona kunyungudutsa waya yakanaka yemhangura.
Asi girazi haritsva.Kupisa kwatinogona kuona ndiko kuvandudza mashandiro ejira refiberglass, uye pamusoro pejira refiberglass rakaputirwa neresin zvinhu, kana zvakanamirwa tsvina.Yakachena girazi faibha jira kana yakavharwa neimwe yakakwira tembiricha isingachinjiki, inogona kugadzirwa yezvipfeko zvinoramba, magirovhosi anotangisa, zvigadzirwa zvegumbeze zvinoramba.Zvisinei, kana ikasvika pakusangana neganda zvakananga, iyo yakaputsika fiber inotsamwisa ganda zvakanyanya uye inokonzera kuputika.
Zvakajairwa girazi fiber monofilm dhayamita mune anopfuura 9-13 microns, pazasi 6 microns yegirazi faibha inoyangarara, inogona yakananga mumapapu chubhu, inogona kukonzera chirwere chekufema, saka nyatso tarisa kune, 6 microns pazasi kazhinji anotengeswa kunze kwenyika.Masks ehunyanzvi anofanirwa kupfekwa panguva yekugadzira mabasa.Kana iwe uchinge uchisangana nayo kazhinji, inogona kupinda mumapapu ako uye kukonzera pneumoconiosis.
Kana muviri ukabata girazi faibha, ganda harina kunaka richava allergic, asi kazhinji harizove nekukuvadza kukuru, ganda harina kunaka rinogona kunge riri bhegi diki, ndiko kusawirirana.
Kana zvakaoma kuibvisa kubva muzvipfeko, zvirove kakawanda munzvimbo ine mhepo.Mushure mekugeza uye kuomeswa, zviri nyore kuibvisa nekuirova nebazi.
