Zvichienderana nekuchinja kuri kuita indasitiri yepasi rose yerabha nepurasitiki kuenda kukushanda zvakanaka, kuchengetedzwa kwezvakatipoteredza uye kushanda kwakasiyana-siyana, Chlorinated Polyethylene (CPE) yakazvigadzira sechinhu chakakosha mukugadzirisa polymer. Sechinzvimbo chikuru chekugadzirisa purasitiki, CPE 135A inoonekwa nekugadzikana kwayo kwakanyanya pakushanda uye kushanda zvakanaka kwemari, ichibatsira pakuvandudza chigadzirwa chePVC chakasimba, nekukura kwemusika nguva dzose uye kushandiswa kwakakura muzvivakwa, mapaipi, mapaneli nedzimwe nzvimbo dzakakosha.
CPE 135A ipurasitiki yakasviba yakagadzirwa ne chlorination ye polyethylene ine huwandu hwakanyanya, inoonekwa seupfu huchena, husina chepfu uye husina hwema hune chlorine inodzorwa zvakanaka ye35±2%. Simba rayo guru nderekuti inoenderana zvakanyanya nePVC yakasimba: panguva yekugadzirisa, inoumba chimiro che network chine mativi matatu mukati mePVC matrix, ichisimudzira zvakanyanya kusimba kwechigadzirwa ichi patembiricha yakaderera uye kuramba kukanganiswa, ichivimbisa kuchinjika kwakanaka kunyangwe pa -30℃ uye kugadzirisa dambudziko rekusagadzikana kwetembiricha yakaderera muPVC yakajairika. Pamusoro pezvo, inopa kugona kwemamiriro ekunze kwakanaka, kunonoka kwemoto, kuramba ngura yemakemikari uye kudzivirira magetsi, ichiwedzera hupenyu hwebasa rezvigadzirwa zvekupedzisira uye ichizviita kuti zvive zvakanaka pakuvaka kunze, mapaipi emaindasitiri, zvikamu zvemagetsi nezvimwe zvinoshandiswa zvakaoma.
Inonyanya kushandiswa semuchina wekugadzirisa magadzirirwo ePVC akaomarara, CPE 135A inoshandiswa zvakanyanya mumagadzirirwo emasuo nemahwindo ePVC, mapaipi emvura uye emvura, machubhu ewaya, mabhodhi efoam, machira anoburitswa uye zvinhu zvakagadzirwa nemapuranga nepurasitiki. Mukugadzira magadzirirwo, kuwedzera zvikamu 9-12 zveCPE 135A kunowedzera simba remagadzirirwo ne30% kusvika 50%; mukugadzira mapaipi, zvikamu 4-6 chete zvinosimudzira kuramba kumanikidzwa uye kushanda kwekupisa kwakaderera, zvichibatsira zvigadzirwa kusangana nezvinodiwa zvepasi rose zvekuvaka. Iine kuyerera kwakanaka kwekugadzirisa uye kupararira, inochinjika zvakanaka kune maitiro ekugadzira ekuwedzera uye kudzvanywa, pasina mvura kana kupatsanurwa, ichibatsira vagadziri kuwedzera kushanda zvakanaka kwekugadzira uye goho rezvigadzirwa.
Kubva muna 2026, indasitiri yeCPE yakaramba iine tsika ye "kugadzikana kwemhando yepamusoro nekugadziriswa kwemitengo zvine musoro" zvichikonzerwa nekuchinja-chinja kwemitengo yezvinhu zvakabikwa uye kuwedzera kudiwa kubva mumisika yezvivakwa nemidziyo yekuvaka. Izvi zvakawedzera kukwikwidzana kweCPE 135A yepamusoro-soro yenyika. Vagadziri vepamusoro vemuno vakavandudza matekinoroji ekugadzira uye maitiro akagadziridzwa ekuvandudza kuchena kwechigadzirwa, kuchena uye kugara kwenguva refu, zvichiita kuti CPE 135A yemuno isagutse chete kudiwa kwepamusoro-soro kwemuno asiwo iwane mukana wakasimba mumisika yekune dzimwe nyika kusanganisira Southeast Asia, Middle East neAfrica, zvichienderana nekukura kwepasi rose pasi peBelt and Road Initiative.
Senzira huru yekuvandudza rabha nemapurasitiki, CPE 135A yagadzirira mikana yakakura yemusika pamwe chete nekuvandudzwa kwepamusoro-soro kwemaindasitiri ezvigadzirwa zvekuvaka nemapurasitiki pasi rose. Nekushandiswa kwakakura kwetekinoroji yekugadzira zvinhu zvakasvibira uye kugadziriswa kwekushanda kuri kuramba kuchienderera mberi, huwandu hwekushandiswa kwayo muzvikamu zvitsva zvesimba nezvinhu zvepamusoro huchawedzera, zvichiisa simba rakasimba mukuchinja nekusimudzira indasitiri.
