BASA RECPE MUZVINHU ZVEKUGADZIRA HUNI NEPLASTIKI ZVEPVC
Uchishandisa magonhi nemahwindo epurasitiki akasanganiswa neCPE nePVC, kusimba, kuomarara uye kushanda kwekupisa kwakaderera zvinovandudzika zvikuru, uye kuramba mamiriro ekunze, kuramba kupisa uye kugadzikana kwemakemikari zvakanaka.
Zvinhu zvakagadzirwa nePVC tree-plastic zvinoumbwa zvakanyanya nePVC resin uye fillers. Kuburikidza nekubatanidza nefibers dzemiti, kugadzirisa tekinoroji yefomula, uye physical mixing modifier neCPE (chlorinated polyethylene) (ine incremental effect uye Modification effect), izvo zvinogona kuvandudza kuomarara, kuomarara, simba, kupisa uye kunonoka kwemurazvo wechigadzirwa (mukati mehuwandu hwezvinodiwa zvemuviri, kana chlorine iri muCPE yakakwira, mhedzisiro yekunonoka kwemurazvo inowedzera), kuwedzera simba rekusimba, kuvandudza kuputsika uye kuramba kukambaira kwePVC.
Maitiro ekuumba zvinhu zvePVC zvinosanganisa miti nepurasitiki akasiyana zvikuru neaya epurasitiki yakajairika. Sezvo chikamu chikuru chefiber yemiti chiri cellulose, cellulose ine huwandu hwakawanda hwema hydroxyl groups, uye aya ma hydroxyl groups anoumba intermolecular hydrogen bonds, izvo zvinoita kuti fiber yemiti ive ne polarity yakasimba uye inonyudzwa mvura. Kune rumwe rutivi, zvinhu zvakawanda zve thermoplastic hazvina polar uye hazvipindi mvura, saka kuwirirana pakati pezviviri kwakaderera zvakanyanya, simba rekubatanidza painterface diki, uye huwandu hwekuzadza fiber yemiti hwakakura, saka kuyerera uye kugona kwekugadzirisa zvinhu zvinova zvisina kunaka, kukanya uye kuumba extrusion zvinova zvakaoma. Nokudaro, kuvandudza kuumbwa kwezvinhu zve wood-plastic composite kwakaita basa rakanaka mukuvandudza kugadzirwa kwe molding uye mashandiro echigadzirwa.
CPE yakatanga kugadzirwa nekukurumidza semuchina wekugadzirisa PVC, uye PVC yakagadziriswa ichiri imwe yenzvimbo dzakakosha dzekushandisa CPE. CPE ine hunhu hwakanaka hwekuzadza, uye huwandu hwakawanda hwezvizadza zvakasiyana-siyana zvinogona kuwedzerwa kuti zvivandudze hunhu hwayo hwekudhonza, kudzvanywa uye kushanduka zvachose, uye kuderedza mitengo. Kukosha kwekushandisa PVC yakagadziriswa kwakawedzerwawo.
Muzvigadzirwa zveCPE zvakagadziriswa software nePVC zvakaoma, zvichienzaniswa nezvimwe polymers zvakaita sePE nePP, mhedzisiro yekudzora moto yakakosha zvikuru. Zvigadzirwa zvakawanda zvePVC zvakaoma zvinogadziriswa neCPE modifier ine chlorine yakawanda ye36%, uye simba rayo guru reimpact rinowanzo kuwanikwa neCPE nemaatomu echlorine akagoverwa zvisina tsarukano pa polyethylene main chain. Nokudaro, iyi modifier inogona kuvandudzwa zvakanyanya maererano nekugona kwayo kugadzikiswa, kupararira, uye simba reimpact.
KUSHANDISWA KWECPE PAMUSORO PEWAYA, TAYI, BHANDE
Sezvo molekyuru yeCPE isina cheni mbiri, ine simba rakanaka rekudzivirira mamiriro ekunze, simba rekudzivirira murazvo, simba rekupisa riri nani pane PVC, mutengo wakaderera uye kushanda zvakanaka.
