Imiyoboro ya polyvinyl chloride (PVC) yahindutse urufatiro rwibikorwa remezo bigezweho, ubwubatsi, hamwe na sisitemu yo gukoresha amazi, bihabwa agaciro kuramba, guhendwa, no guhuza byinshi. Ubwiza bwiyi miyoboro bugenwa ahanini nubwoko bwa PVC resin ikoreshwa mubikorwa byabo.
Muri iki gitabo cyuzuye, tuzacengera mu isi ya PVC, dusuzume ibintu by'ingenzi tugomba gusuzuma muguhitamo resin nziza yo gukora imiyoboro myiza.
Ibintu bigira uruhare mu guhitamo PVC
Guhitamo PVC ikwiye kugirango ikore imiyoboro ikubiyemo gutekereza neza kubintu byinshi, harimo:
Uburemere bwa molekuline: Uburemere bwa molekuline ya PVC ifite uruhare runini mukumenya imbaraga zumuyoboro, gukomera, hamwe nibikorwa muri rusange. Uburemere buke bwa molekuline busanzwe buganisha ku miyoboro ifite imbaraga zo kurwanya ingaruka no gukomera.
Melt Flow Index (MFI): MFI yerekana resin itembera mugihe cyo gukuramo. MFI ibereye ituma habaho gusohora neza, ibipimo byumuyoboro umwe, no kugabanya inenge zitunganijwe.
Ubushyuhe bwa Vicat (Vicat B): Vicat B yerekana ubushyuhe aho resin itangira koroshya munsi yumutwaro. Agaciro karenze Vicat B yerekana ubushyuhe bwiza bwo guhangana nuburinganire bwimiterere yimiyoboro.
Ibyongeweho: Ibisigarira bya PVC akenshi bikozwe ninyongeramusaruro kugirango uzamure imitungo nibiranga gutunganya. Inyongeramusaruro zisanzwe zirimo stabilisateur, kuzuza, amavuta, hamwe nimpinduka.
Ubwoko bwa PVC Resin yo gukora imiyoboro
Ukurikije ibintu bimaze kuvugwa, PVC ibisigazwa byo gukora imiyoboro irashobora gushyirwa mubice bibiri byingenzi:
Guhagarika PVC (S-PVC): Ibisigarira bya S-PVC bikozwe hakoreshejwe uburyo bwo guhagarika polymerisime, bikavamo uduce duto twa serefegitura hamwe no gukwirakwiza uburemere bwa molekile. Zitanga impirimbanyi nziza zingaruka zingaruka, gukomera, nibiranga gutunganya.
Emulsion PVC (E-PVC): Ibisigarira bya E-PVC bikozwe muburyo bwa emulion polymerisation, bitanga uduce duto duto hamwe no gukwirakwiza uburemere buke bwa molekile. Mubisanzwe bagaragaza imbaraga zingaruka zikomeye hamwe no gukomera ugereranije na S-PVC.
Guhitamo Resin nziza kubyo ukeneye
Guhitamo ibyuma bya PVC bikwiranye no kubyara imiyoboro biterwa na progaramu yihariye hamwe nibyifuzo bya pipe. Kurugero, imiyoboro igenewe gukoreshwa bisaba ingufu zisigara zifite uburemere buke bwa molekuline hamwe nagaciro ka Vicat B kugirango ubone imbaraga zihagije nubushyuhe.
Ibinyuranye, imiyoboro ikoreshwa idafite ingufu, nk'amazi cyangwa kuhira, irashobora gushyira imbere imbaraga zingaruka no koroshya gutunganya, bigatuma E-PVC isubira guhitamo neza.
Umwanzuro
Guhitamo PVC resin ni ikintu gikomeye cyo gukora imiyoboro myiza ya PVC. Mugusobanukirwa ibintu byingenzi bigira ingaruka kumahitamo ya resin hamwe nimiterere yubwoko butandukanye bwa resin, abatunganya imiyoboro barashobora gufata ibyemezo byuzuye bitezimbere imikorere yimiyoboro kandi byujuje ibyifuzo bya porogaramu zitandukanye.
Wibuke ko kugisha inama abatanga ubunararibonye bwa PVC no gushaka ubuyobozi bwa tekiniki birashobora kuba ingirakamaro muguhitamo resin nziza kubyo ukeneye gukora neza.
