[Mhando dzemabhegi akarukwa]

Kugadzirwa kwekunze kunonyanya kuve polyethylene (PE), kugadzirwa kwemumba kwakanyanya polypropylene (PP), imhando ye thermoplastic resin inogadzirwa ne ethylene polymerization. Muindasitiri, inosanganisirawo macopolymers ethylene ane mashoma e-olefin. Polyethylene isina kunhuhwirira, isina chepfu, inonzwa sewakisi, ine yakanakisa yakaderera tembiricha kuramba (yakaderera kushandiswa tembiricha inogona kusvika -70 ~ -100 ℃), yakanaka kemikari kugadzikana, inogona kutsungirira yakawanda yeasidhi uye alkali kukukurwa (hapana oxidation yeasidhi), tembiricha yemukamuri isinganyungudika mune zvese zvinonyungudutsa, kunyura kwemvura kudiki, kuita kwakanakisa kwemagetsi ekudzivirira; Asi polyethylene inonzwa kushushikana kwezvakatipoteredza (kemikari uye michina mhedzisiro) uye ine kushomeka kwekudzivirira kuchembera kwemafuta. Izvo zvinhu zve polyethylene zvinosiyana kubva kumarudzi kune marudzi, kunyanya zvichienderana nekugadzirwa kwema molecular uye density. Zvigadzirwa zvine density yakasiyana (0.91 ~ 0.96g / cm3) zvinogona kuwanikwa kuburikidza nekushandisa nzira dzakasiyana dzekugadzira. Polyethylene inogona kugadziriswa neyakajairwa thermoplastic molding nzira (ona purasitiki kugadzirisa). Inoshandiswa zvakanyanya mukugadzira firimu, mudziyo, pombi, waya imwe chete, waya uye tambo, zvinodiwa zvezuva nezuva, nezvimwewo, uye inogona kushandiswa seyakakwira-frequency insulation zvinhu zveTV, radar, nezvimwewo. Nekuvandudzwa kweindasitiri yepetrochemical, kugadzirwa kwepolyethylene kwakagadzirwa nekukurumidza, kubuda kweinenge 1/4 yehuwandu hwekugadzirwa kwepurasitiki. Muna 1983, iyo yakazara kugadzirwa kwe polyethylene yaive 24.65Mt, uye kugona kwechirimwa chiri kuvakwa kwaive 3.16Mt.

Polypropylene (PP)

Iyo thermoplastic resin yakagadzirwa nepolymerization yepropylene. Kune matatu magadzirirwo eisochronous, asina kunyoreswa uye interchronous zvigadzirwa, uye isochronous zvigadzirwa ndizvo zvakakosha zvezvigadzirwa zveindasitiri. Polypropylene inosanganisirawo copolymers yepropylene uye shoma shoma ye ethylene. Kazhinji translucent isina ruvara yakasimba, isina hwema isina chepfu. Nekuti chimiro chakashambidzika uye chakanyanya kunyungudika, saka nzvimbo yekunyunguduka inosvika 167 ℃, kupisa kupisa, zvigadzirwa zvinogona kushandiswa zviputi disinfection ndiko kwakanakira kwayo. Iine density ye0.90g/cm3, ndiyo yakareruka pasi rose purasitiki. Corrosion resistance, tensile simba 30MPa, simba, rigidity uye pachena zviri nani pane polyethylene. Izvo zvakashata ndeye yakaderera tembiricha kukanganisa kuramba uye kuchembera kuri nyore, uko kunogona kukundwa nekugadzirisa uye nekuwedzera kwe antioxidant zvakateerana.

Rudzi rwebhegi rakarukwa rinowanzo chena kana grey chena, isina chepfu uye haina kuravira, kazhinji isingakuvadzi kumuviri wemunhu, kunyangwe ichigadzirwa neakasiyana emakemikari epurasitiki, asi kudzivirira kwayo kwezvakatipoteredza kwakasimba, uye simba rekudzokorora rakakura;

Mabhegi akarukwa anoshandiswa zvakanyanya, anonyanya kushandiswa kurongedza uye kurongedza zvinyorwa zvakasiyana, zvakanyanya kushandiswa mumaindasitiri;

Plastiki yakarukwa bhegi yakagadzirwa nepolypropylene resin sechinhu chikuru mbishi, iyo inoburitswa uye yakatambanudzwa kuita sirika yakatsetseka, yozorukwa nekugadzira mabhegi.

Iyo composite yepurasitiki yakarukwa bhegi yakavakirwa pajira repurasitiki rakarukwa, iro rinogadzirwa nenzira yekukunguruka.

Iyi nhevedzano yezvigadzirwa inoshandiswa kurongedza hupfu kana granular yakasimba zvinhu uye zvinochinjika zvinyorwa. Iyo composite yepurasitiki yakarukwa bhegi yakakamurwa kuita maviri mu-rimwe bhegi uye matatu mu-rimwe bhegi zvinoenderana nehukuru hwezvinhu.

Zvinoenderana nemaitiro ekusona, inogona kukamurwa kuita bhegi rezasi rekusona, bhegi rezasi rekusona, kuisa muhomwe uye kubatanidza bhegi rekusona.

Zvinoenderana nehupamhi hunobudirira hwebhegi, inogona kukamurwa kuita 350, 450, 500, 550, 600, 650 uye 700mm. Madiro akakosha achabvumiranwa nemapato ese.
