Nekuvandudzwa kweindasitiri yemazuva ano, epoxy resin iri kuwedzera kushandiswa muminda yekuvaka, mota, aerospace, etc. Izvo zvakanakisa zveepoxy resin zvinoita kuti iite basa rakakosha mukubatana, kugadzirisa uye kugadzirisa pamusoro pezvinhu zvakaita sedombo nesimbi. Nekudaro, nekuwedzera kwekushandiswa kwe epoxy resin, dambudziko rekurasa marara rakakwevera zvishoma nezvishoma kutarisa. Kana epoxy resin tsvina isina kubatwa zvakanaka, inokonzeresa kusvibiswa kwakakomba kune zvakatipoteredza. Nokudaro, zvinonyanya kukosha kuongorora nzira dzekurapa dzakatipoteredza. Ichi chinyorwa chichakurukura nezve chizvarwa, nzira dzekurapa uye zvakatipoteredza hushamwari kurapwa tekinoroji ye epoxy resin tsvina.
Hunhu uye mashandisirwo eEpoxy Resin
Epoxy resin (Epoxy Resin) inhengo yepolymer inoumbwa nekuita kwe epoxy compounds uye mishonga yekurapa. Iyo ine yakanakisa kugadzikana kwemakemikari, corrosion resistance, kupfeka kuramba uye kunamatira kwakanaka. Inowanzo shandiswa mukuputira, zvinonamira, zvinosanganiswa zvinhu, zvemagetsi chikamu packaging, dombo bonding uye mamwe minda. Epoxy resin inonyanya kukosha muindasitiri yematombo. Inogona kushandiswa kuwedzera kuoma, permeability kuramba, kupfeka kuramba uye kushongedza kwedombo.
Nekuda kwekushandiswa kwakakura kwe epoxy resin, tsvina epoxy resin inogadzirwa panguva yekugadziriswa kwematombo yave nyaya yezvakatipoteredza isingagone kufuratirwa. Iyo yakakwira molecular chimiro che epoxy resin pachayo inoita kuti zviome kudzikisira munzvimbo yechisikigo. Kana ikaraswa kana kubatwa zvisina kunaka, inogona kukonzera kusvibisa ivhu, mvura nemhepo.
Nzvimbo huru dze epoxy resin tsvina
Kurasa mukugadzira
Mukugadzira epoxy resin, pane imwe huwandu hwemarara anogadzirwa, anosanganisira asina kukwana kuita epoxy resin, kurapa agent masara, uye tsvina yemvura mushure mekuchenesa midziyo. Kana marara aya akasagadziriswa, kubuda kwakananga kunokonzeresa mutoro mukuru pane zvakatipoteredza.
Tsvina inogadzirwa panguva yekuvaka
Muindasitiri yematombo, epoxy resin inowanzoshandiswa kusungirira, kugadzirisa uye kupfeka pamusoro. Munguva yekuvaka, yakawandisa epoxy resin, tsvina inokonzerwa nekukanganisa kwekushanda, uye yakaraswa epoxy resin coatings ichava manyuko ekusvibiswa kwezvakatipoteredza.
Kurasa mukushandiswa kwezuva nezuva
Upenyu hwebasa rebwe rakagadziriswa ne epoxy resin hurefu, asi nekufamba kwenguva, pamusoro pebwe rinogona kukuvara, uye epoxy resin tsvina inoshandiswa mukugadzirisa yakavewo chikamu chemarara.
Zvakatipoteredza hushamwari kurapwa nzira epoxy resin tsvina
Kurapa kwe epoxy resin tsvina, nzira dzekurapa dzinoenderana nemhoteredzo dzinofanirwa kutarisisa kudzikisira kusvibiswa kwezvakatipoteredza, kugadzirisa kudzoreredza zviwanikwa, uye kutevedzera mitemo yekuchengetedzwa kwezvakatipoteredza. Izvi zvinotevera nzira dzakawanda dzekurapa dzinozivikanwa.
1. Nzira yekurapa kwepanyama
Nzira dzekurapa dzepanyama dzinowanzobata marara epoxy resin tsvina nemakanika kuti ideredze kukanganisa kwayo kune zvakatipoteredza.
Kune chikamu chisina kupora che epoxy resin tsvina, inogona kudzokororwa nenzira dzenyama. Tsvina inodziiswa kune imwe tembiricha kuti iite mvura zvakare, uyezve inogona kushandiswa mukugadzira mushure mekurapa. Iyi nzira inogona kunyatso kudzikisa huwandu hwemarara anogadzirwa uye kuderedza kushandiswa kweiyo epoxy resin itsva.
Imwe nzira yakajairika yekurapa kwemuviri ndeyekumanikidza marara epoxy resin kudzikisa huwandu hwayo uye kufambisa kunotevera kurapwa. Munguva yekumanikidzana, mumiririri wekurapa anogona kuwedzerwa kuita tsvina epoxy resin iumbe dzakaomarara dzakaomarara zvidimbu kuderedza kusvibiswa kunharaunda.
2. Kemikari kurapwa nzira
Nzira dzekurapa makemikari dzinonyanya kuvimba nemaitiro emakemikari kushandura chimiro chemarara, nekudaro kuderedza kusvibiswa uye kuwedzera kudzoreredza mitengo.
Kushatiswa kwe epoxy resin tsvina kunowanzo kuwanikwa nekukasira kuparara kwekuita. Mamwe makemikari ejenti, akadai seasidhi, alkalis kana oxidants, anogona kuita ne epoxy resins, zvichikonzera shanduko muchimiro chavo chemolecular uye pakupedzisira kuwana kurapwa kusingakuvadzi. Iyi nzira inogona kunyatso kudzikisa huwandu hwemarara uye kuishandura kuita zvinhu zvisingakuvadzi.
Iyo nzira yekunyungudutsa inoshandisa chaiyo solvent kunyungudutsa zvinokuvadza zvikamu mu epoxy resin tsvina, uyezve inogadzirisa iyo solvent. Iyi nzira yakakodzera mamiriro ezvinhu apo epoxy resin ine zvikamu zvinonyunguduka uye inogona kunyatso kuvandudza kushanda kwekurapa.
3. Biological kurapwa nzira
The biological treatment method inyanzvi inoshandisa tupukanana kusvibisa marara. Microorganisms inokwanisa kukanganisa organic zvinhu uye inogona kushandura epoxy resin tsvina kuita zvinhu zvisingakuvadzi kuburikidza ne biodegradation.
Mumakore achangopfuura, vatsvakurudzi vakawana kuti mamwe ma microorganisms anogona kukanganisa zvimwe zvikamu zve epoxy resin pasi pemamiriro ezvinhu ezvakatipoteredza. Kushandisa utachiona uhwu kurapa biodegradation hakungogone kuderedza kusvibiswa kwemarara, asiwo kupa mazano matsva ekudzoreredza tsvina.
Enzyme catalytic degradation tekinoroji inoshandisa inokonzeresa chiitiko chemamwe ma enzymes kuti iparadze macheni epolymer epoxy resin, nekudaro kuwana kurapwa kwemarara. Kunyangwe tsvagiridzo panzira iyi ichiri mudanho rekuongorora, ine mukana mukuru webudiriro.
4. Thermal kurapwa nzira
Iyo yekupisa yekurapa nzira inoshandura epoxy resin tsvina kuita gasi risingakuvadzi kana chinhu chakasimba nekudziya kwepamusoro-tembiricha.
Kupisa ndiyo imwe yenzira dzechinyakare dzekurapa epoxy resin tsvina. Kuburikidza nekupisa kwepamusoro-tembiricha, epoxy resin tsvina inosvibiswa kuita magasi asingakuvadzi akadai semhute yemvura uye kabhoni dhaikisaidhi. Munguva yekupisa, tembiricha uye kubuda kwegasi kunofanirwa kudzorwa zvakanyanya kudzivirira kugadzirwa kwezvinhu zvine chepfu senge dioxin.
Iyo yekupisa yekupwanya nzira inobvisa epoxy resin tsvina kuita yakaderera mamorekuru huremu zvinhu nekuipisa munzvimbo isina oxygen. Izvi zvakaderera molecular huremu zvinhu zvinogona kudzokororwa kana kushandiswazve sesimba.
Kudzokorodza uye kushandiswazve kwe epoxy resin tsvina
Pamusoro pemaitiro echinyakare ekurapa, kudzokorodza uye kushandisazve epoxy resin tsvina zvakare inzira inoshanda yekudzivirira kwezvakatipoteredza.
Kugadzirwa kwe recycled epoxy resin
Nekudzokorodza tsvina epoxy resin uye kudzoreredza zvimiro zvayo zvepakutanga kuburikidza nemakemikari kurapwa kana nzira dzemuviri, nyowani epoxy resin inogona kuvandudzwa. Iyi epoxy resin yakadzokororwa inogona kutsiva itsva epoxy resin mune mamwe mashoma-inodiwa maapplication uye kuderedza kushandiswa kwezviwanikwa zvitsva.
Kugadzirwa kwezvinhu zvakasanganiswa
Mushure mekurapwa, epoxy resin tsvina inogona kushandiswa sechikamu chezvakaumbwa zvinhu uye inoshandiswa mumaindasitiri akadai sekuvaka, mota, uye ndege. Kushandura marara kuita zvinhu zvitsva zvinobatsira hakugone chete kuderedza kusvibiswa kwemarara, asiwo kunatsiridza kushandiswa kwezviwanikwa.
Summary
Nekushandiswa kwakapararira kwe epoxy resin muindasitiri yematombo, kurapwa kwekuchengetedza kwezvakatipoteredza kwemarara kwave kuwedzera kukosha. Kunyangwe nzira dzechinyakare dzemuviri, dzemakemikari uye dzekupisa dzichishanda, nekuvandudzwa kwezvinodiwa zvekuchengetedza nharaunda, tekinoroji yakawanda yekudzokorodza uye kushandisa zvakare tekinoroji inoda kutariswa. Nekutora nzira dzepamusoro dzekuchengetedza kuchengetedzwa kwezvakatipoteredza, njodzi dze epoxy resin tsvina dzinogona kudzorwa zvinobudirira, uye inopawo nzira nyowani yekushandisa kwakasimba kwezviwanikwa. Mune ramangwana, makambani anofanirwa kuwedzera kutsvagisa nekusimudzira kuedza kusimudzira tekinoroji yekurapa kwegirinhi ye epoxy resin tsvina kuti iwane win-win mamiriro ekuchengetedza kwezvakatipoteredza uye resource recycling.
