Vatengi vazhinji kuburikidza newebhusaiti yedu kufonera kubvunza rudzi rwebhegi rakarukwa uye renji rekushandisa, iro nhasi dongle rakarukwa bhegi xiaobian kutsanangura rudzi rwebhegi rakarukwa uye renji yekushandisa.
Mabhegi akarukwa anozivikanwawo semabhegi enyoka. Ipurasitiki, inonyanya kushandiswa kurongedza. Zvishandiso zvaro zvinowanzova polyethylene, polypropylene uye mamwe makemikari epurasitiki mambishi. Izvi zvinotevera nhanganyaya yemhando uye mashandisirwo emabhegi akarukwa.
type
Chinhu chikuru chekugadzirwa kwekunze ndeye polyethylene (PE), nepo chinhu chikuru chekugadzirwa mudzimba chiri polypropylene (PP), thermoplastic resin yakagadzirwa ne ethylene polymerization. Muindasitiri, macopolymers ethylene ane mashoma e-olefin anosanganisirwa zvakare. Inonhuhwirira, isina chepfu, ine waxy polyethylene, ine yakanakisa yakaderera tembiricha kuramba (minimum kushanda tembiricha kusvika -70 ~ 100 ℃), yakanaka kemikari kugadzikana, kuramba kune yakawanda asidhi uye alkali ngura (oxidation resistant acid), isinganyunguriki mune zvakawanda zvinonyungudutsa pakamuri tembiricha, kunyura kwemvura shoma, kuita kwakanakisa kwemagetsi ekudzivirira; Iyo polyethylene (kemikari uye magetsi ekudzivirira) nekuda kwekunetseka kwezvakatipoteredza; Mechanical effect) yakanyanya kugadzikana, kushomeka kuramba kupisa kuchembera. Izvo zvinhu zve polyethylene zvinosiyana kubva kumarudzi kune marudzi, kunyanya zvichienderana nekugadzirwa kwayo kwema molecular uye density. Zvigadzirwa zvine density dzakasiyana (0.91 kusvika 0.96 g / cm3) zvinogona kuwanikwa nenzira dzakasiyana dzekugadzira. Polyethylene inogona kugadziriswa neyakajairwa thermoplastic kuumba maitiro (ona Plastic processing). Inoshandiswa zvakanyanya mukugadzira firimu, midziyo, mapaipi, waya imwe chete, waya uye tambo, zvinodiwa zvezuva nezuva, nezvimwewo. Inogonawo kushandiswa seyakanyanya frequency insulation zvinhu zveTV uye radar. Nekuvandudzwa kweindasitiri yepetrochemical, kugadzirwa kwepolyethylene kwakakura nekukurumidza, kuverengera chikamu chimwe muzvina chekugadzirwa kwepurasitiki. Muna 1983, nyika yose yekugadzirwa kwepolyethylene yaiva 24.65 Mt, uye kukwanisa kwechirimwa chiri kuvakwa chaiva 3.16 Mt.
polypropylene
Thermoplastic resin yakagadzirwa nepropylene polymerization. Kune matatu magadzirirwo eiyo yakazara isomorphism, random uye interisomorphism. Izvo zvikamu zvikuru zvezvigadzirwa zveindasitiri zvine homogenous zvinhu. Polypropylene inosanganisirawo copolymers yepropylene uye shoma shoma ye ethylene. Inowanzoita translucent colorless yakasimba, isinganakidze uye isina chepfu. Nekuda kwechimiro chayo chenguva dzose uye yakakwirira crystallinity, nzvimbo yekunyunguduka inosvika 167 ℃. Iyo inodzivirira kupisa uye chigadzirwa chinogona kuvharwa nemhepo. Density ye0.90 g/cm3 ndiyo yakareruka pasirese purasitiki. Corrosion resistance, tensile simba 30 MPa, simba, rigidity uye pachena zviri nani pane polyethylene. Izvo zvisingabatsiri ndezvakaderera kukanganisa kuramba uye kuchembera kuri nyore pane yakaderera tembiricha, iyo inogona kukundwa nekugadzirisa uye nekuwedzera antioxidants zvakateerana.
Ruvara rwemabhegi akarukwa kazhinji ruchena kana kuti chena, rusina chepfu uye harunakidze, kazhinji hahuna kukuvadza muviri wemunhu. Kunyangwe iwo akagadzirwa kubva kune akasiyana emakemikari epurasitiki, iwo ane hushamwari hwezvakatipoteredza uye anogona kushandiswazve.
Mabhegi akarukwa anoshandiswa zvakanyanya, kunyanya kurongedza zvinhu zvakasiyana, uye anoshandiswa zvakanyanya mumaindasitiri.
Plastic yakarukwa bhegi yakagadzirwa nepolypropylene resin, yakasimudzwa uye yakatambanudzwa kuita sirika yakati sandara, yozorukwa kuita masaga.
Mabhegi epurasitiki akasanganiswa akarukwa anogadzirwa nejira repurasitiki kuburikidza nerukova.
Inoshandiswa kurongedza hupfu kana granular yakasimba zvinhu uye zvinyorwa zvinochinjika. Iyo composite yepurasitiki yakarukwa bhegi yakakamurwa kuita maviri mu-rimwe bhegi uye matatu mu-rimwe bhegi zvinoenderana nehukuru hwezvinhu.
Zvinoenderana neiyo nzira yekusona, inogona kukamurwa kuita bhegi rezasi rekusona, bhegi rekusona, rekupinza bhegi uye bhegi rekusona.
Zvichienderana nehupamhi hunobudirira hwebhegi, inogona kukamurwa kuva 450, 500, 550, 600, 650 uye 700 mm. Madiro akakosha anobvumiranwa nemutengesi nemutengi.
Range yekushandiswa
1. Kurongedza mabhegi ezvigadzirwa zveindasitiri nezvekurima
Nekuvandudzwa uye kushandiswa kwemabhegi emidziyo anochinjika, mabhegi epurasitiki akarukwa emidziyo anoshandiswa zvakanyanya muMarine, indasitiri yekufambisa uye yekurongedza uye zvigadzirwa zvekurima. Mabhegi epurasitiki akarukwa ave kushandiswa zvakanyanya mukurongedzerwa kwezvinhu zvekurima. Mabhegi epurasitiki akarukwa ave kushandiswa zvakanyanya muzvigadzirwa zvemumvura. Kurongedza, kurongedza chikafu chehuku, zvekufukidzira purazi, kurima zvirimwa shading, windproof, pekugara chimvuramabwe nezvimwe zvinhu. Zvigadzirwa zvakajairika: bhegi rakarukwa, bhegi remakemikari rakarukwa, putty poda yakarukwa bhegi, urea yakarukwa bhegi, yemiriwo net bhegi, michero net bhegi, nezvimwe.
2. Kurongedza chikafu
Mupunga, hupfu uye kumwe kurongedza kwechikafu zvishoma nezvishoma shandisa masaga akarukwa. Mabhegi akarukwa anowanza ndeaya: masaga akarukwa mupunga, masaga akarukwa upfu, masaga akarukwa echibage nemamwe masaga akarukwa.
3. Zvekushanya
Matende enguva pfupi, maamburera, mabhegi ekufambisa uye mabhegi muindasitiri yekushanya anoshandiswa kugadzira machira akarukwa epurasitiki. Matende emarudzi akasiyana-siyana anoshandiswa zvakanyanya sedzimba
Matende enguva pfupi, maamburera, mabhegi ekufambisa uye mabhegi muindasitiri yekushanya anoshandiswa kugadzira machira akarukwa epurasitiki. Matende anoshandiswa zvakanyanya sezvinhu zvekuvharisa zvekutakura nekuchengetedza, kutsiva matende edonje anorema uye akaumbwa. Fenzi uye mesh muzvivakwa zvakare anoshandiswa zvakanyanya mumachira epurasitiki. Zvakajairika: mabhegi ekutakura, mabhegi ekurongedza. Mapakeji ekutakura zvinhu, mapakeji ekutakura, nezvimwe.
Injiniya zvinhu
Kubva pakuvandudzwa kwegeotextile muma1980s, munda wekushandisa wejira rakarukwa repurasitiki rave richikura, richishandiswa zvakanyanya mukuchengetedza mvura diki, simba remagetsi, mugwagwa mukuru, njanji, chiteshi, kuvaka migodhi uye kuvaka kwemauto. Mune aya mapurojekiti, geosynthetics ine mabasa ekusefa, kudhiraivha, kusimbisa, kuzviparadzanisa nevamwe uye kudhiza kudzora. Plastic geotextiles ndeimwe yekugadzira geotextiles.
Zvinhu zvinodzora mafashamo
Mabhegi akarukwa akakosha pakudzora mafashamo. Izvo zvakare zvakakosha mukuvaka kwemigumo, nzizi, njanji nemigwagwa. Iwo mabhegi ekudzivirira - ruzivo rwakarukwa, mabhegi ekudzivirira kusanaya kwemvura uye mabhegi ekudzivirira mafashama.
Pamusoro idiki make up yemunhu wese kupedzisa kweakarukwa rudzi rwebhegi uye chiyero chekushandiswa kwekubvunza kwakabatana, kuburikidza nekugovana zvemukati, mhando uye mashandisirwo emhando yemabhegi akarukwa ane kumwe kuziva, kana iwe uchida kupinda zvakadzika mubhegi reruzivo rwemusika, unogona kubata mutengesi mukambani yedu, kana kumabvazuva uye bhegi rakarukwa pa-iyo-nzvimbo inokurukurwa mukuferefeta uku.
