Ni ibihe biranga Polyvinyl Chloride (PVC)?

Zimwe mu ngaruka zikomeye za Polyvinyl Chloride (PVC) ni izi zikurikira:

1. Ubucucike:PVC ni nini cyane ugereranije na pulasitiki nyinshi (uburemere bwihariye buri hafi 1.4)
2. Ubukungu:PVC iraboneka byoroshye kandi ihendutse.
3. Ubukomere:PVC ikomeye ni nziza mu bukonje no kuramba.
4. Imbaraga:PVC ikomeye ifite imbaraga nziza zo gukurura.

Polyvinyl Chloride ni ibikoresho bya "thermoplastic" (bitandukanye na "thermoset"), bifitanye isano n'uburyo plastiki isubiza ubushyuhe. Ibikoresho bya thermoplastic biba amazi aho bishongesha (urugero rwa PVC ruri hagati ya dogere selisiyusi 100 zo hasi cyane n'agaciro ko hejuru nka dogere selisiyusi 260 bitewe n'inyongera). Ikintu cy'ingenzi ku bijyanye na thermoplastic ni uko bishobora gushyushywa kugeza aho bishongesha, bigakonjeshwa, kandi bigashyushywa nta kwangirika gukomeye. Aho gushya, thermoplastic nka polypropylene liquefy ituma byoroshye kubitera hanyuma bigakoreshwa. Mu buryo bunyuranye, thermoset plastics zishobora gushyushywa rimwe gusa (ubusanzwe mu gihe cyo gushushanya inshinge). Gushyushya kwa mbere bituma ibikoresho bya thermoset bikomera (bisa na epoxy y'ibice 2), bigatuma habaho impinduka mu buryo budashobora gusubizwa inyuma. Iyo ugerageje gushyushya thermoset plastic ku bushyuhe bwinshi ku nshuro ya kabiri, byashya gusa. Iyi miterere ituma ibikoresho bya thermoset bitagomba kongera gukoreshwa.

PVC itanga uburyo butandukanye bwo kuyikoresha n'inyungu mu nganda nyinshi haba mu buryo bwayo bukomeye no mu buryo bworoshye. By'umwihariko, PVC ikomeye ifite ubucucike bwinshi bwa pulasitiki, bigatuma ikomera cyane kandi muri rusange ikomeye cyane. Iraboneka kandi ihendutse, hamwe n'imiterere myinshi ya pulasitiki iramba, bituma yoroha kuyikoresha mu nganda nyinshi nko mu bwubatsi.

PVC ifite imiterere ikomeye cyane kandi yoroheje, bigatuma ikundwa cyane mu bwubatsi, mu by'amazi, no mu bindi bikorwa by'inganda. Byongeye kandi, chlorine nyinshi irimo ituma ibikoresho bidashobora gushya, iyi ikaba indi mpamvu yatumye ikunzwe cyane mu nganda zitandukanye.
