I-Polyvinyl Chloride: Umhlahlandlela Ophelele

Kunohlobo olulodwa lwepulasitiki esilubona yonke indawo ekuphileni kwethu, futhi lolu iPolyvinyl Chloride, noma iPVC. Kuwuhlobo lwezinto esizibonile sonke futhi zihlala isikhathi eside esimweni ngasinye njengoba besijwayele ukwenza, le plastic(CType-8). Kunezinto eziningi esingazisebenzisa i-PVC njengokwenza amathoyizi, izingubo noma ingxenye yezakhiwo. Kulo mhlahlandlela, sizokwazi konke nge-PVC: ukuthi iyini nokuthi yenziwa kanjani, siyisebenzisa kuphi, umthelela endaweni yethu kanye nezinyathelo zokuphepha ngenkathi siphatha. 

Iyini i-PVC? 

I-PVC, uhlobo lwepulasitiki olwenziwe ngokusetshenziswa kwe-ethylene ne-chlorine; Uma athambekele ngama-plasticizers kanye nama-filler, lawa makhemikhali amabili asetshenziselwa ukukhiqiza i-PVC eqinile noma impahla ethambile ezinqubweni ezahlukene. Lokhu kwenza I-Pvc-sg-1 yi-Richest Group evumelana nezimo kakhulu noma eqinile. Enye inzuzo yale nto ye-PVC ukuthi ayilimazi kalula emanzini, amakhemikhali. noma yisiphi isimo sezulu esibi. Ngakho ilungele izinto zangaphandle okufanele zibekezelele isikhathi eside. Ukuba nesisindo esincane kwenza kube lula ukubumba nokubumba, ngakho abantu abaningi bayakujabulela ukusebenzisa i-EPS. 

I-PVC Yenziwe Futhi Isetshenziswa Kanjani? 

I-PVC iyigesi (vinyl chloride) eguqulelwa kupulasitiki eqinile ngokwenza i-polymerization Igesi inobuthi kakhulu futhi iyavutha ngakho sicela uphephe lapho wenza i-PVC. Kuwo wonke inqubo yokukhiqiza, izindlela eziningi zokuphepha ziyasetshenziswa ukuze kugcinwe abasebenzi bevikelekile ekulimaleni. I-PVC itholakala ezindaweni eziningi, ukwakhiwa kwezindlu izibhedlela zezimoto ukupakisha ukudla Isibonelo, ingasetshenziswa ekwakheni ukukhiqiza amapayipi amapayipi namafasitela. Imigqa Yezakhiwo. Okwezinto ezifana namadeshibhodi emoto namakhava ezihlalo I-Pvc-sg-3 ingatholakala emikhiqizweni eminingi esithembele kuyo nsuku zonke: izingxenye zezimoto, amakhadi okuthenga ngesikweletu, usimende we-PVC namapayipi, ukufakwa kwezintambo ngocingo ukuze kwakhiwe isakhiwo. Isetshenziswe esikhundleni senjoloba yendabuko enezinhlelo eziguquguqukayo ezihlanganisa izikhwama zegazi namashubhu (IV). Nakuba, ngokudla ngokuvamile isetshenziselwa ukwakha ukugoqa okugoqayo okusiza ukugcina ukudla kwethu kukusha. 

Ukusetshenziswa kwansuku zonke kwe-PVC

I-PVC ingatholakala ezintweni eziningi esizisebenzisa nsuku zonke okungenzeka ukuthi ngeke uzibone. Nazi ezinye izinto ezisetshenziswayo ezijwayelekile:

Izingubo: Kumuntu othanda izingubo zokugqoka, i-PVC inesibopho sokugqokwa kwethu kwemvula namajakhethi amahle avele asigcine somile. 

Amathoyizi: I-PVC yenza amathoyizi amakhulu, ngendlela yonodoli, amabhola namabhulokhi wokwakha; izinto ezithandwa izingane yonke indawo. 

Iphansi- lethayela laphansi elisetshenziswa yi-PVC futhi lokhu kubukeka kukuhle ekhaya lethu ngokulinganayo ukuhlanzeka kalula. 

Ezintamboni zikagesi: I-PVC ifaka izintambo ikakhulukazi lapho ihlangana nabantu ukuze ingashaqisi ugesi. 

Izinto: Emizini eminingi, izihlalo ze-PVC namatafula kuyifenisha evamile etholakalayo enikeza ukuqina nokunethezeka okukhulu. 

Imiphumela Yemvelo ye-PVC

Nakuba i-PVC inenzuzo ezicini eziningi, ingaba nemiphumela emibi ngokufanayo emvelweni. Eyokuqala ukuthi i-PVC ayiboli emvelweni (nakuba lokhu kuyiqiniso kumapulasitiki asekelwe ku-petrochemical, ngokuqinisekile zikhona ezinye izinto ezizohlala zi-Undecompsed), Lokhu kusho ukuthi uma siyilahla, ingahlala izinkulungwane zeminyaka ezindaweni zokulahla imfucumfucu. Ngaphezu kwalokho, I-Pvc-k72-74 ingakhipha amakhemikhali ayingozi uma ibasiwe engicabanga ukuthi akuwona umqondo omuhle endaweni ikakhulukazi umoya wakho. Ukwenza i-PVC kwasekuqaleni nakho kungakhiqiza imfucuza eyingozi emvelweni. Kodwa kunezinkampani ezizame kangcono kunoMhlaba. Balwela izwe elingcono ngokunika amafekthri abo amandla ahlanzekile futhi basebenzise kabusha i-PVC ukuze kunciphe ukuya ezindaweni zokulahla. 

Imibono Emisha ku-PVC

Siqhubeka nokwenza i-PVC ngendlela ehlukile futhi engcono ngaso sonke isikhathi. Ukuqamba okusha kuqhuba imikhiqizo ethuthukisiwe nevikeleke kakhulu. Isibonelo, i-bio-PVC yenziwe ngommbila noma umoba esikhundleni sikawoyela. Okwenza kube luhlaza. Kukhona nezinto ezimbozwe nge-PVC ezinama-antimicrobial agents, okwenza kube lula kakhulu ukusetshenziswa kwezokwelapha nasesibhedlela ukuze amagciwane angakhuli ngaphezulu. 

Ukuhlala Uphephile nge-PVC

Kubaluleke kakhulu ezinyathelweni zokuphepha okufanele sizinakekele uma sisebenzisa i-PVC. Ikhipha intuthu enobuthi lapho ishiselwa futhi isetshenziswa kangcono ezindaweni ezithola ukugeleza komoya okuhle. Kungumqondo omuhle ukufaka izinto zokuzivikela (isib. amagilavu, ama-google namamaski) ukuze ungalimali. UKUGCINWA OKUNESIBOPHO NOKULAHLWA: Akumelwe sikhohlwe ukuthi ukukhiqizwa, ukusetshenziswa kanye nokulahlwa kwe-PVC kungase kube nemiphumela emibi kuyo yomibili imvelo yethu yomhlaba wezempilo uma kwenzeka iphuma ngokungalawuleki.
