Polyvinyl chloride (PVC) ni polymer yakozwe na polymerisation ya vinyl chloride monomer (VCM) imbere yabatangije nka peroxide na azo compound cyangwa nuburyo bwa polymerisiyumu yubusa ikoresheje urumuri cyangwa ubushyuhe. PVC ni ibikoresho bya polymer bifashisha atom ya chlorine kugirango isimbuze atome ya hydrogène muri polyethylene, na vinyl chloride homopolymers na vinyl chloride copolymers hamwe hamwe bita vinyl chloride resin.
Iminyururu ya molekile ya PVC irimo atome ya polarine ya chlorine ikomeye hamwe nimbaraga nyinshi za intermolecular, zituma ibicuruzwa bya PVC birushaho gukomera, bikomeye, ndetse no kumashini, kandi bifite ububobere buke bwumuriro (flame retardancy bivuga umutungo ikintu gifite cyangwa ikintu gifite nyuma yo kuvurwa gutinza cyane ikwirakwizwa ry'umuriro); icyakora, dielectric ihoraho hamwe na dielectric igihombo inguni tangent indangagaciro nini kuruta iya PE.
Ububiko bwa PVC burimo umubare muto wububiko bubiri, iminyururu yashami hamwe nibisigisigi byatangijwe bisigaye muri reaction ya polymerisation, hiyongereyeho atome ya chlorine na hydrogène hagati ya atome ebyiri za karubone zegeranye, zidahumanya byoroshye, bikaviramo kwangirika kwa PVC byoroshye mugikorwa. y'umucyo n'ubushyuhe. Kubwibyo, ibicuruzwa bya PVC bigomba kongeramo stabilisateur yubushyuhe, nka calcium-zinc stabilisateur, barium-zinc stabilisateur, bayobora ubushyuhe bwumunyu, stabilisateur tin stabilisateur, nibindi.
Porogaramu nyamukuru
PVC ije muburyo butandukanye kandi irashobora gutunganywa muburyo butandukanye, harimo gukanda, gusohora, gutera inshinge, no gutwikira. Plastike ya PVC isanzwe ikoreshwa mugukora firime, uruhu rwubukorikori, kubika insinga ninsinga, ibicuruzwa bikomeye, hasi, ibikoresho, ibikoresho bya siporo, nibindi.
Ibicuruzwa bya PVC mubisanzwe bishyirwa mubyiciro 3: bikomeye, igice-gikomeye kandi cyoroshye. Ibicuruzwa bikomeye kandi byigice bitunganyirizwa bitunganijwe nta na plastike nkeya, mugihe ibicuruzwa byoroshye bitunganyirizwa hamwe na plastike nyinshi. Nyuma yo kongeramo plasitike, ubushyuhe bwikirahure burashobora kugabanuka, bigatuma byoroha gutunganywa mubushyuhe buke kandi bikongerera ubworoherane na plastike yumunyururu wa molekile, kandi bigatuma bishoboka gukora ibicuruzwa byoroshye byoroshye mubushyuhe bwicyumba.
1. Umwirondoro wa PVC
Ahanini ikoreshwa mugukora inzugi n'amadirishya nibikoresho bizigama ingufu.
2. Imiyoboro ya PVC
Imiyoboro ya PVC ifite ubwoko bwinshi, imikorere myiza nuburyo bunini bwo gukoresha, kandi ifite umwanya wingenzi ku isoko.
3. Filime ya PVC
PVC irashobora gukorwa muri firime ibonerana cyangwa ifite amabara yubugari bwihariye ukoresheje kalendari, kandi firime yakozwe nubu buryo yitwa firime ya kalendari. Ibikoresho fatizo bya PVC birashobora kandi gutwarwa muri firime ukoresheje imashini zogosha, kandi firime yakozwe nubu buryo yitwa blow molding film. Filime irashobora gukoreshwa mubikorwa byinshi kandi irashobora gutunganyirizwa mumifuka, amakoti yimvura, ameza yameza, umwenda, ibikinisho byaka, nibindi mugukata no gufunga ubushyuhe. Filime nini ibonerana irashobora gukoreshwa mukubaka pariki na pariki ya plastike, cyangwa ikoreshwa nka firime yo hasi.
4. Ikibaho cya PVC
Wongeyeho na stabilisateur, amavuta yo kwisiga hamwe nuwuzuza, hanyuma nyuma yo kuvanga, PVC irashobora gusohorwa mumiyoboro itandukanye ya kaliberi ikomeye, imiyoboro imeze nkimiyoboro isukuye hamwe na extruder, hanyuma igakoreshwa nkumuyoboro, amazi yo kunywa, insinga z'amashanyarazi cyangwa intoki zintambwe. Impapuro za kalendari zuzuye kandi zishyushye kugirango zikore impapuro zikomeye zubunini butandukanye. Amabati arashobora kugabanywa muburyo bwifuzwa hanyuma akayasudira akayaga gashyushye akoresheje inkoni yo gusudira ya PVC mubigega bitandukanye bibika imiti irwanya imiti, imiyoboro n'ibikoresho, nibindi.
5. PVC ibicuruzwa byoroshye
Ukoresheje extruder, irashobora gukururwa mumazu, insinga, insinga, nibindi.; ukoresheje imashini ibumba inshinge hamwe nuburyo butandukanye, irashobora gukorwa muri sandali ya plastike, inkweto zinkweto, kunyerera, ibikinisho, ibice byimodoka, nibindi.
6. Ibikoresho byo gupakira PVC
Ibicuruzwa bya PVC byo gupakira cyane kubintu bitandukanye, firime nurupapuro rukomeye. Ibikoresho bya PVC bikorerwa cyane cyane mumazi yubutare, ibinyobwa, amacupa yo kwisiga, ariko no kubipakira amavuta meza.
7. PVC kuruhande no hasi
Kuruhande rwa PVC bikoreshwa cyane cyane mugusimbuza aluminiyumu, amabati ya PVC, usibye igice cyibisigisigi bya PVC, ibindi bice byose ni ibikoresho bitunganyirizwa hamwe, ibifunga, ibyuzuza nibindi bikoresho, cyane cyane bikoreshwa mukibuga cyindege cyindege nahandi hantu hakomeye butaka.
8. Ibicuruzwa bya PVC
Ibicuruzwa bya PVC birashobora kuboneka ahantu hose mubuzima bwacu bwa buri munsi. PVC ikoreshwa mugukora uruhu rwubukorikori butandukanye kumifuka yimizigo, ibicuruzwa bya siporo nka basketball, imipira yumupira wamaguru nudupira twa rugby. Irakoreshwa kandi mugukora imyenda hamwe nimikandara idasanzwe yo gukingira. Imyenda ya PVC yimyenda muri rusange ni imyenda ikurura (nta gutwikira bisabwa) nka ponchos, ipantaro yumwana, amakoti yimpu yubukorikori hamwe na bote yimvura itandukanye. PVC ikoreshwa kandi mubicuruzwa byinshi by'imikino n'imyidagaduro nk'ibikinisho, inyandiko n'ibicuruzwa bya siporo.
