Mapombi ePolyvinyl chloride (PVC) ave musimboti wezvivakwa zvemazuva ano, kuvaka, uye masisitimu epombi, anokosheswa nekusimba, kugona, uye kuita zvakasiyana. Hunhu hwemapombi aya hunonyanya kutsanangurwa nemhando yePVC resin inoshandiswa mukugadzira kwavo.
Mugwaro rino rakazara, tichaongorora nyika yePVC resin, tichiongorora zvinhu zvakakosha zvekufunga nezvazvo pakusarudza rakanakisa resin yemhando yepamusoro yekugadzirwa kwepombi.
Zvinhu Zvinokurudzira PVC Resin Sarudzo
Kusarudza yakakodzera PVC resin yekugadzirwa kwepombi kunosanganisira kunyatsotarisisa zvinhu zvakati wandei, zvinosanganisira:
Molecular Weight: Huremu hwePVC resin hunoita basa rakakosha pakuona kusimba kwepombi, kuoma, uye kuita kwese. Yepamusoro mamorekuru uremu resins anowanzo tungamira kune mapaipi ane yakawedzera kukanganisa kupikisa uye kusimba.
Melt Flow Index (MFI): MFI inoratidza kuyerera kweresin panguva yeextrusion process. A MFI yakakodzera inovimbisa extrusion yakatsetseka, yunifomu pombi zviyero, uye kuderedzwa kwekugadzirisa kukanganisa.
Vicat Softening Temperature (Vicat B): Vicat B inomiririra tembiricha iyo resin inotanga kupfava pasi pemutoro. Iyo yepamusoro Vicat B kukosha inoratidza zvirinani kupisa kupisa uye kugadzikana kwedimensional yemapombi.
Additives: PVC resins inowanzogadzirwa nezvinowedzerwa kuti iwedzere zvimiro zvavo uye maitiro ekugadzirisa. Zvakajairika zvinowedzera zvinosanganisira stabilizers, fillers, lubricant, uye maitiro ekugadzirisa.
Mhando dzePVC Resin yePipe Production
Kubva pane zvataurwa pamusoro apa, PVC resins yekugadzirwa kwepombi inogona kuiswa muzvikamu zviviri zvikuru:
Suspension PVC (S-PVC): S-PVC resins inogadzirwa uchishandisa suspension polymerization process, zvichikonzera spherical particles ane yakafara molecular uremu kugovera. Vanopa chiyero chakanaka chesimba rekuita, kuoma, uye maitiro ekugadzirisa.
Emulsion PVC (E-PVC): E-PVC resins inogadzirwa kuburikidza ne emulsion polymerization process, ichibereka akatsetseka zvidimbu zvine nhete mamorekuru uremu kugovera. Ivo vanowanzo ratidza yakakwirira simba simba uye kuderera kuomarara zvichienzaniswa neS-PVC resins.
Kusarudza iyo Yakanakisa Resin Yezvido Zvako
Sarudzo yeakanyanya kukodzera PVC resin yekugadzira pombi zvinoenderana neiyo chaiyo application uye inodiwa pombi zvivakwa. Semuyenzaniso, mapaipi akagadzirirwa kushandiswa kwekumanikidza anoda resin ane huremu hwemamorekuru uye Vicat B hunhu kuve nechokwadi chekusimba kwakakwana uye kudzivirira kupisa.
Kusiyana neizvi, mapaipi ezvisina-pressure application, senge dhiraivha kana kudiridza, anogona kuisa pamberi pesimba rekuita uye nyore kugadzirisa, zvichiita kuti E-PVC resin ive sarudzo yakakodzera.
Mhedziso
PVC resin kusarudzwa chinhu chakakosha pakugadzira emhando yepamusoro PVC pombi. Nekunzwisisa zvinhu zvakakosha zvinopesvedzera kusarudzwa kweresin uye zvimiro zvemarudzi akasiyana resin, vagadziri vepombi vanogona kuita sarudzo dzine ruzivo dzinogonesa kuita kwepombi uye kusangana nezvinodiwa zvekushandisa kwakasiyana.
Rangarira kuti kubvunzana nevane ruzivo PVC resin vatengesi uye kutsvaga tekinoroji nhungamiro inogona kuve yakakosha pakusarudza iyo yakakodzera resin kune yako chaiyo yekugadzira pombi zvinodiwa.
