Vatengi vazhinji kuburikidza newebhusaiti yedu vanofonera kuti vabvunze nezvemhando yebhegi rakarukwa uye mhando dzezvishandiso, nhasi uno dongle woven bag xiaobian kutsanangura rudzi rwebhegi rakarukwa uye mhando dzezvishandiso.
Mabhegi akarukwa anozivikanwawo semabhegi eganda renyoka. Ipurasitiki, inonyanya kushandiswa pakurongedza. Zvinhu zvayo zvekugadzira zvinowanzova polyethylene, polypropylene nezvimwe zvinhu zvepurasitiki zvemakemikari. Zvinotevera ndezvekutanga kutsanangura mhando nemashandisirwo emabhegi akarukwa.
mhando
Chinhu chikuru chekugadzirwa kwekunze ipolyethylene (PE), nepo chinhu chikuru chekugadzirwa kwemumba chiri polypropylene (PP), resin yethermoplastic yakagadzirwa ne ethylene polymerization. Mumaindasitiri, ma copolymers e ethylene ane huwandu hushoma hwe -olefin anowanikwawo. Polyethylene isina hwema, isina chepfu, ine wakisi, ine resistance yakaderera yekupisa (tembiricha yekushanda inosvika -70 ~ 100℃), kugadzikana kwakanaka kwemakemikari, kuramba acid yakawanda uye alkali corrosion (oxidation resistant acid), isinganyungudike mu solvents yakawanda patembiricha yemumba, kunyungudika kwemvura shoma, kushanda zvakanaka kwekudzivirira magetsi; I polyethylene (chemical uye electrical insulation) yekushushikana kwezvakatipoteredza; Mechanical effect) inonyanya kusimba, kuramba kupisa kukwegura. Hunhu hwe polyethylene hunosiyana kubva kumarudzi kusvika kumarudzi, kunyanya zvichienderana nechimiro chayo chemamorekuru uye density. Zvigadzirwa zvine densities dzakasiyana (0.91 kusvika 0.96 g/cm3) zvinogona kuwanikwa nenzira dzakasiyana dzekugadzira. Polyethylene inogona kugadziriswa nenzira yakajairika yekugadzira thermoplastic (ona Plastic processing). Inoshandiswa zvakanyanya mukugadzira mafirimu, magaba, mapaipi, waya imwe chete, waya netambo, zvinodiwa zvezuva nezuva, nezvimwewo. Inogona zvakare kushandiswa sezvinhu zvinodzivirira mafambiro epamusoro eTV neradar. Nekukura kweindasitiri yemafuta, kugadzirwa kwepolyethylene kwakawedzera nekukurumidza, zvichiita chikamu chimwe muzvina chekugadzirwa kwepurasitiki. Muna 1983, kugona kwekugadzira polyethylene pasi rose kwaive 24.65 Mt, uye kugona kwefekitori iri kuvakwa kwaive 3.16 Mt.
polypropylene
Resin yethermoplastic inogadzirwa nepropylene polymerization. Kune marongerwo matatu e total isomorphism, random uye interisomorphism. Zvikamu zvikuru zvezvigadzirwa zvemaindasitiri zvinhu zvakafanana. Polypropylene inosanganisirawo copolymers yepropylene uye ethylene shoma. Kazhinji isimbi inopenya isina ruvara, haina kunaka uye haina chepfu. Nekuda kwechimiro chayo chakajairika uye crystallinity yakakura, nzvimbo yekunyunguduka inosvika 167℃. Inodzivirira kupisa uye chigadzirwa ichi chinogona kucheneswa nemhepo. Density ye 0.90 g/cm3 ndiyo purasitiki yakareruka kupfuura dzose. Kuramba ngura, simba rekudhonza 30 MPa, simba, kuomarara uye kujeka zviri nani pane polyethylene. Zvakaipa ndezvekuti inodzivirira kukanganiswa zvishoma uye kukwegura nyore patembiricha yakaderera, izvo zvinogona kukundwa nekuchinja uye kuwedzera ma antioxidants zvakateerana.
Ruvara rwemabhegi akarukwa runowanzova ruchena kana kuti ruchena, haruna chepfu uye haruna kunaka, kazhinji harukuvadzi muviri wemunhu. Kunyangwe akagadzirwa nemapurasitiki akasiyana-siyana emakemikari, haakuvadzi nharaunda uye anogona kudzokororwa.
Mabhegi akarukwa anoshandiswa zvakanyanya, kunyanya pakurongedza zvinhu zvakasiyana-siyana, uye anoshandiswa zvakanyanya mumaindasitiri.
Bhegi rakarukwa repurasitiki rinogadzirwa ne polypropylene resin, rinoburitswa uye rinotambanudzwa kuita siriki yakatsetseka, uye rozorukwa mumabhegi.
Mabhegi epurasitiki akarukwa akagadzirwa nejira repurasitiki kuburikidza nerwizi.
Inoshandiswa pakurongedza hupfu kana zvinhu zvakasimba zvakasanganiswa uye zvinhu zvinochinjika. Bhegi rakarukwa repurasitiki rakakamurwa kuita bhegi mbiri dziri mu-rimwe uye bhegi nhatu dziri mu-rimwe zvichienderana nehukuru hwechinhu chacho.
Zvichienderana nenzira yekusona, inogona kukamurwa kuita bhegi repasi rekusona, bhegi remucheto wekusona, bhegi rekuisa uye bhegi rekusona rekubatanidza.
Zvichienderana nehupamhi hunoshanda hwebhegi, rinogona kukamurwa kuita 450, 500, 550, 600, 650 uye 700 mm. Tsanangudzo dzakakosha dzinobvumiranwa nemutengesi nemutengi.
Range yekushandiswa
1. Mabhegi ekurongedza ezvigadzirwa zvemaindasitiri nezvekurima
Nekugadzirwa nekushandiswa kwemabhegi emidziyo anochinjika, mabhegi epurasitiki akarukwa anoshandiswa zvakanyanya muindasitiri yeMarine, yekutakura nekurongedza uye yekurima. Mabhegi epurasitiki akarukwa anoshandiswa zvakanyanya mukupakata zvigadzirwa zvekurima. Mabhegi epurasitiki akarukwa anoshandiswa zvakanyanya muzvigadzirwa zvemumvura. Kurongedza, kurongedza chikafu chehuku, zvinhu zvekufukidza purazi, mumvuri wekurima zvirimwa, kudzivirira mhepo, nzvimbo yekuchengetera mvura nechimvuramabwe nezvimwe zvinhu. Zvigadzirwa zvakajairika: bhegi rakarukwa rekudya, bhegi rakarukwa remakemikari, bhegi rakarukwa reputty, bhegi rakarukwa reurea, bhegi remuriwo, bhegi remichero, nezvimwewo.
2. Kurongedza chikafu
Mupunga, hupfu nezvimwe zvekudya zvinopakirwa zvishoma nezvishoma. Mabhegi akarukwa anowanzo shandiswa ndeanoti: mabhegi akarukwa nemupunga, mabhegi akarukwa nemupunga, mabhegi akarukwa nemuchibage uye mamwe mabhegi akarukwa.
3. Kutakurwa kwevashanyi
Matende echinguvana, amburera, mabhegi ekufambisa nemabhegi muindasitiri yekushanya zvinoshandiswa kugadzira machira epurasitiki akarukwa. Matende emhando dzakasiyana-siyana anoshandiswa zvakanyanya senzvimbo dzekugara.
Matende echinguvana, amburera, mabhegi ekufambisa nemabhegi muindasitiri yekushanya zvinoshandiswa pakugadzira machira epurasitiki akarukwa. Matende anoshandiswa zvakanyanya sezvinhu zvekufukidza zvekutakura nekuchengetera, zvichitsiva matende edonje anorema uye ane chakuvhuvhu. Fenzi nemambure muzvivakwa zvinoshandiswawo zvakanyanya mumachira epurasitiki. Zvakajairika: mabhegi ekufambisa, mabhegi ekufambisa ekufambisa. Mapakeji ekutakura, mapakeji ekutakura, nezvimwewo.
Zvishandiso zveinjiniya
Kubva pakatanga kugadzirwa kwegeotextile muma1980, nzvimbo yekushandisa machira akarukwa epurasitiki yave ichikura, ichishandiswa zvakanyanya mukuchengetedza mvura diki, magetsi, migwagwa mikuru, njanji, chiteshi chengarava, kuvaka migodhi nekuvaka mauto. Mumapurojekiti aya, geosynthetics ine mabasa ekusefa, kubvisa mvura, kusimbisa, kupatsanura uye kudzora kubuda kwemvura. Mapurasitiki geotextile ndeimwe yemagadzirirwo egeotextile.
Zvinhu zvekudzora mafashamo
Mabhegi akarukwa akakosha pakudzivirira mafashamo. Anokoshawo pakuvaka migero, nzizi, njanji nemigwagwa. Mabhegi akarukwa anodzivirira ruzivo, mabhegi akarukwa anodzivirira kuoma kwemvura uye mabhegi akarukwa anodzivirira mafashamo.
Pamusoro apa pane makeup diki kune wese munhu anopedzisa mhando yebhegi rakarukwa uye huwandu hwekushandisa kwekutaurirana kwakabatana, kuburikidza nekugovana zviri mukati, mhando uye huwandu hwemashandisirwo emabhegi akarukwa, une ruzivo rwakadzama, kana uchida kudzika mubhegi reruzivo rwemusika, unogona kubata mutengesi wekambani yedu, kana kuEast uye bhegi rakarukwa ipapo ipapo, kutaurirana kwakabatana kunokurukurwa mupepa rino.
