Ikintu cyose Ukeneye Kumenya kuri Polyvinyl Chloride (PVC) Plastike

Polyvinyl Chloride (PVC) ni kimwe mu bikoresho byinshi kandi bikoreshwa cyane muri termoplastique ku isi. Azwiho kuramba, guhendwa, no kurwanya ibintu bidukikije, PVC ikoreshwa mu nganda zitandukanye, kuva ubwubatsi kugeza ubuvuzi. Muri iyi ngingo, tuzasesengura PVC icyo aricyo, imiterere yacyo, imikoreshereze, nibindi byinshi.

Polyvinyl Chloride (PVC) ni iki?

Polyvinyl Chloride (PVC) ni polymer yubukorikori ikozwe muri polymerisation ya vinyl chloride. Yatangijwe bwa mbere mu 1872 itangira umusaruro wubucuruzi muri 1920 na Sosiyete BF Goodrich. PVC ikoreshwa cyane mubikorwa byubwubatsi, ariko kuyikoresha nabyo birerekana ibyapa, ubuvuzi, imyenda, nibindi byinshi.

PVC iraboneka muburyo bubiri bwibanze:

1. PVC Rigid (uPVC)- PVC idafite amashanyarazi ni ibikoresho bikomeye, biramba bikoreshwa mugukoresha amazi, amakadiri yidirishya, nibindi bikorwa byubaka.
2. PVC ihindagurika- Yahinduwe na plasitike, PVC yoroheje iroroshye, irigoramye, kandi ikoreshwa cyane mubicuruzwa nko gukwirakwiza insinga z'amashanyarazi, hasi, no guhuza byoroshye.

Ibiranga Choride ya Polyvinyl (PVC)

Imiterere ya PVC ituma iba ibikoresho byatoranijwe kubisabwa byinshi:

• Ubucucike: PVC yuzuye kurusha izindi plastiki nyinshi, hamwe nuburemere bwihariye bwa 1.4.
• Kuramba: PVC irwanya kwangirika guturuka ku bidukikije, imiti, n’imirasire ya UV, bigatuma biba byiza ku bicuruzwa biramba.
• Imbaraga: PVC Rigid ifite imbaraga zidasanzwe kandi zikomeye, mugihe PVC ihindagurika ikomeza guhinduka nimbaraga.
• Gusubiramo: PVC irashobora gukoreshwa byoroshye kandi igaragazwa na resin code “3,” ishigikira kuramba.

Ibyingenzi byingenzi bya PVC

• Gushonga Ubushyuhe: 100 ° C kugeza 260 ° C (212 ° F kugeza 500 ° F), bitewe ninyongera.
• Imbaraga: PVC ihindagurika iri hagati ya 6.9 na 25 MPa, mugihe PVC ikomeye cyane irakomeye kuri 34 kugeza 62 MPa.
• Ubushyuhe: PVC irashobora kwihanganira ubushyuhe bugera kuri 92 ° C (198 ° F) mbere yo guhinduka.
• Kurwanya ruswa: PVC irwanya cyane imiti na alkalies, bigatuma ihitamo igihe kirekire mubikorwa bitandukanye.

Ubwoko bwa PVC: Rigid na Flexible

PVC iraboneka cyane muburyo bubiri:

1. PVC Rigid(uPVC): Iyi fomu irakomeye kandi ikoreshwa kenshi mubikorwa byubwubatsi nka pompe na side. Bikunze kwitwa “vin
2. PVC ihindagurika.

Kuki PVC ikoreshwa cyane?

Icyamamare cya PVC gikomoka kuricyoigiciro gito, kuboneka, naUbwoko butandukanye. Rigid PVC itoneshwa cyane cyane mubikorwa byubaka bitewe nimbaraga zayo nigihe kirekire, mugihe ubworoherane bwa PVC bworoshye nubworoherane bituma biba byiza kubicuruzwa bisaba kunama, nko kuvura ubuvuzi cyangwa hasi.

Nigute PVC Yakozwe?

PVC ikorwa muburyo bumwe muburyo butatu bwa polymerisation:

• Guhagarika polymerisation
• Emulion polymerisation
• Polimerisiyasi

Izi nzira zirimo polymerisation ya vinyl chloride monomers muri chloride ikomeye ya polyvinyl, ishobora noneho gutunganyirizwa mubicuruzwa bitandukanye.

PVC mugutezimbere Prototype: Imashini ya CNC, Icapiro rya 3D, hamwe no Gutera inshinge

Mugihe PVC ari ibikoresho bizwi cyane munganda zitandukanye, itanga ibibazo bimwe na bimwe mubijyanye na prototyping ninganda:

• Imashini ya CNC.
• Icapiro rya 3D: PVC ntabwo isanzwe ikoreshwa mugucapisha 3D kubera imiterere yayo. Byongeye kandi, isohora imyuka yubumara iyo ishyushye, bigatuma iba ibikoresho byiza kuriyi ntego.
• Gutera inshinge: PVC irashoborainshinge, ariko iyi nzira isaba guhumeka neza hamwe nibikoresho birwanya ruswa bitewe no gusohora imyuka yangiza nka hydrogène chloride (HCl).

PVC ifite uburozi?

PVC irashobora kurekuraimyotsi y'ubumaraiyo yatwitse cyangwa ashyushye, cyane cyane mubikorwa byinganda nko gucapa 3D, gutunganya CNC, no guterwa inshinge. Ibikoresho birashobora gusohora imyuka yangiza nkachlorobenzenenahydrogen chloride, bishobora guteza ingaruka ku buzima. Ni ngombwa gukoresha umwuka uhagije hamwe nibikoresho birinda mugihe cyo gutunganya.

Ibyiza bya PVC

• Ikiguzi: PVC nimwe mubintu bya plastiki bihendutse biboneka.
• Kuramba: Irwanya ingaruka, imiti, no kwangiza ibidukikije.
• Imbaraga: PVC itanga imbaraga zidasanzwe, cyane muburyo bukomeye.
• Guhindagurika: PVC irashobora kubumbabumbwa, gukata, no gushingwa muburyo butandukanye bwibicuruzwa, bigatuma bihinduka mubikorwa bitandukanye.

Ibibi bya PVC

• Ubushyuhe.
• Ibyuka bihumanya: Iyo yatwitse cyangwa yashonze, PVC isohora imyotsi yangiza, bisaba gufata neza na protocole yumutekano.
• Kamere ibora: PVC irashobora kwangirika kubikoresho byuma nibikoresho niba bidakozwe neza.

Umwanzuro

Polyvinyl Chloride (PVC) ni ibintu byinshi bidasanzwe bitanga impagarike nziza yubushobozi, imbaraga, no kurwanya ibidukikije. Uburyo butandukanye, bukomeye kandi bworoshye, butuma bukoreshwa mu nganda nyinshi, kuva mubwubatsi kugeza kubuvuzi. Icyakora, ni ngombwa gusobanukirwa ingaruka zishobora guteza ubuzima hamwe nimbogamizi mugutunganya PVC, cyane cyane kubyuka byangiza na kamere yangirika. Iyo ikozwe neza, PVC nibikoresho ntagereranywa bikomeje kugira uruhare runini mubikorwa byubwubatsi bugezweho.
