Hunhu hwakasiyana-siyana uye mashandisirwo eCPE chlorinated polyethylene

CPE， Chlorinated polyethylene, inozivikanwawo se chlorinated polyethylene, inogadzirwa kubva ku polyethylene yepamusoro-soro (HDPE) kuburikidza ne chlorination process. Hunhu hwechinhu ichi ndechekuti maatomu ehydrogen ari mucheni yayo yemamorekuru anotsiviwa zvishoma nemaatomu echlorine, zvichiratidza chimiro chemakemikari chakasiyana. CPE yakaomeswa inoonekwa seupfu chena uye haina chepfu uye yakachengeteka. Fomura yayo yemamorekuru ndeye CH2-CHCl-CH2-CH2] n, yakapfupikiswa se CPE kana CM muchiRungu. Sezvinhu zvepolymer zvakazara, CPE haingori chete ine simba rakanaka rekudzivirira mamiriro ekunze uye murazvo, asiwo inoratidza kugadzikana kwakanaka kwekupisa, izvo zvinonyanya kushamisa kupfuura PVC. Pamusoro pezvo, inewo mabhenefiti emutengo wakaderera uye kushanda zvakanaka. Panyaya yekunyungudika, CPE inonyungudika mu aromatic hydrocarbons uye halogenated hydrocarbons, asi hainyungudike mu aliphatic hydrocarbons. Kana tembiricha ikapfuura 170 ℃, inotanga kuora nekuburitsa hydrogen chloride gasi. Nekuda kwechimiro chayo chemakemikari chakasimba, CPE inoratidzawo simba rakanaka rekudzivirira kukwegura, simba rekudzivirira kutonhora, simba rekudzivirira makemikari, simba rekudzivirira ozone, uye simba remagetsi. Panguva imwe chete, inoenderana zvakanaka uye inogona kushandiswa, uye inogona kusanganiswa nezvinhu zvakaita sePVC, PE, PS, uye rabha, zvichivandudza hunhu hwezvinhu izvi.
CPE ine mashandisirwo akasiyana-siyana muminda yakawanda
1. Kushandiswa mu membrane yekudzivirira mvura
Kamudzira kekudzivirira mvura yePVC kakawedzerwa neCPE, kane hunhu hwakanaka hweCPE, kakawedzera simba rayo rekudhonza ne80% uye simba rekubvaruka ne50%. Panguva imwe chete, simba rayo rekudzivirira mamiriro ekunze, simba rekudzivirira kupisa kwakaderera, uye simba rekudzivirira kukwegura zvakawedzerwawo zvakakwana, uye kanofarirwa zvikuru nemadhipatimendi ekuvaka (nekuwedzera kweCPE kunodzorwa pa10% -15%). Pamusoro pezvo, kamudzira kekudzivirira mvura yeCLOPrene rabha CPE uye kamudzira kekudzivirira mvura yeCLOPrene rabha CPE styrene butadiene rabha rabha rava chizvarwa chitsva chezvinhu zvakanaka zvekudzivirira mvura nesimba razvo guru, kusimba kwakanyanya, kuwedzera kwakanyanya, pamwe nezvakanakira zvakawanda zvakaita sekudzivirira ngura, simba rekudzivirira kupisa kwakanyanya, simba rekudzivirira kutonhora, simba rekudzivirira kukwegura, uye kunonoka kwemurazvo, uye zvine mikana yakawanda yemusika.
2. Kugadzirwa kwemasuo nemahwindo epurasitiki
Nekusanganisa CPE nePVC, kusimba, uye kushanda zvakanaka kwemasuo nemahwindo epurasitiki zvinovandudzika zvakanyanya, ukuwo zvichiramba zvakanaka mumamiriro ekunze, kusapisa, uye kugadzikana kwemakemikari. Rudzi urwu rwemasuo nemahwindo epurasitiki runokwanisika kutenga, harupindi ngura, uye runouya nemavara akasiyana-siyana. Kana ruchienzaniswa nemasuo nemahwindo ealuminium alloy, rune zvakanakira zvakawanda uye zvishoma nezvishoma rwave chinhu chitsva chinodiwa pamusika.
3. Kushandiswa kwewaya ne sheath ye tambo
Kuwedzerwa kweCPE kwakavandudza mashandiro ekupisa kwecathodic, mashandiro ekudzivirira kukwegura uye hunhu hwemuviri uye hwemakanika hwewaya netambo dzemachira. Panguva imwe chete, zvinhu zvekuputira waya netambo zvakagadzirwa zvakanyanya neCPE zvinoratidzawo mashandiro akanaka kwazvo.
4. Kugadzirwa kwemapombi erabha netsoka dzeshangu
CPE inogona kugadzira mapombi asingatsvedzere mafuta, acid, makombama, ozone, uye Freon, uye yakakodzera kugadzira mapombi ehydraulic, mapombi anotonhorera, mapombi emafuta, nezvimwewo. Panguva imwe chete, soli yeganda remombe inogadzirwa neCPE semuviri mukuru inoratidzawo kushanda kwakanaka.
