Nangona kunjalo, uhlobo oluqinileyo lwepolyvinyl chloride (imo yePVC)? Luhlobo lweplastiki olubeka ukusetyenziswa okuninzi kwiindawo ezahlukeneyo. Ngokuqhelekileyo kubonakala kwizinto zendlu yaziwa ngokuba yiPVC okanye i-polyvinyl chloride.
Eli bakala lePVC luhlobo lweplastiki eyomeleleyo eyaziwa ngokuba yiRigid PVC. Oku kubenza bomelele kwaye banokunyamezela uxhatshazo lwakho oluninzi nokuba ulusebenzisa kakhulu. Ngenxa yoko, ilungele kakhulu inani elikhulu leemveliso. I-PVC eqinileyo ikwasetyenziselwa ezinye iinjongo kuba yomelele ngokwaneleyo ukuxhathisa uninzi lweekhemikhali. Kuthiwa ayinyangeki kumawaka ezinto ezahlukeneyo ezinokuyonakalisa, nto leyo eyenza amabango athile ezinto ezisetyenziswa kwimibhobho nakwimibhobho ethwala ulwelo. Ukongeza, ukuqina kwayo kuvumela ukuba ibunjwe kuzo zonke iintlobo zeemilo kunye nobukhulu kunye nenqanaba eliphakathi lokukhululeka - eqinile iPVC. Ngenxa yeempawu zayo ezisebenzayo, iPVC ingasetyenziswa kwizakhelo zefestile okanye iingcango (okanye ezinye iiyunithi) ezifakwa ngokulula kwizakhiwo zezindlu nokunye.
I-PVC engqongqo isetyenziswa ngokubanzi kwizicelo ezininzi, ngenxa yeempawu zayo ezibalaseleyo zomzimba kunye nokuqhubekeka okunokufumaneka phantse naphi na ukusuka kulwakhiwo ukuya kwimoto kunye nezonyango. IiPVCs, umzekelo zisebenza njengeyona mibhobho yolwakhiwo eyomeleleyo phaya kwaye isetyenziswa kakhulu ukuthutha amanzi okanye naluphi na uhlobo lolwelo ukusuka kwindawo ethile ukuya kwenye ngokukhuselekileyo. Zomelele kakhulu kwaye zinceda ukuhamba kakuhle kweenkqubo zamanzi. Ezi festile ziphezulu kwimfuno kwaye namhlanje njengesakhelo sePVC sefestile ziindleko eziphantsi zokugcinwa kwezindlu kunye nezakhiwo ezinikezela ngokunciphisa. Ingaphakathi lihlala lifudumele ebusika kwaye lipholile ehlotyeni, nto leyo egcina amandla kuphela kodwa nemali. Ukongeza kwicandelo lemoto, ikwasetyenziselwa iimoto zangaphakathi kunye nabaninzi. Oku kwelinye icala kuthintela imoto yangaphakathi ekonakalisa ubuhle babo bokuqala kwaye ngaloo ndlela ibancede baphile ixesha elide. Ikwasebenza kakuhle kwezempilo, yiyo loo nto iyinto eqhelekileyo kwiityhubhu zonyango kunye nezixhobo oogqirha abadinga ukukhathalela izigulana.
Ukwenziwa kwePVC eqinileyo kuqala ngezinto ezingafaniyo nekrwada. I-vinyl chloride, kunye nezinye izithako ezongezelelweyo ezibizwa ngokuba zizongezo zingundoqo. Hlanganisa, emva koko ushushu wenze iplastiki. Iplastiki yokubumba ukuvelisa amadama kwiimilo ezahlukeneyo ezicwangcisiweyo kunye nobukhulu kufuna ukuba bayidlulisele xa izinto zilungiselelwa ukuthengiswa, oko kukuthi, ukwenziwa. Inokwakheka ngokulula kwimibhobho emide, okanye amashiti asicaba ukuze asetyenziswe njengezakhelo zefestile. Emva kwesi sigaba sokubumba, iimveliso ziya kulawulwa umgangatho ngokuvavanya. Ezi ayingawo amacandelo endiya kuwasebenzisa kulwakhiwo lwam lwangaphambili lwe-13B kodwa endaweni yoko luseto olufanele lukhuseleke ngokwaneleyo ukuze luqhube inkonzo ebeluyilelwe.
Siyazi ukuba i-Rigid PVC ineempawu ezifana ne-membrane, kodwa ikwaphakamisa nemiba yokusingqongileyo. Izinto ezininzi zePVC ziqulethe iikhemikhali eziyityhefu, ezifana ne-phthalates kunye nelothe. Inkunkuma eyingozi iyingozi kwindalo esingqongileyo nakubantu xa ilahlwa ngaphandle koqwalaselo olululo. Nangona kunjalo, kukho iindlela ezininzi ezikhuselekileyo kwezi khemikhali zibulalayo. I-PVC ikwayi-100% yezinto ezinokuphinda zisetyenziswe, nto leyo eyenza ukuba ibe luncedo ngakumbi kokusingqongileyo. Oku kunika ukukwazi ukuseyisa kwakhona iimveliso zePVC ezindala kwaye ziphinde zenziwe zibe yizinto ezintsha zobomi obude, itiphu encinci kunye nefuthe lokusingqongileyo. Inde kwaye imfutshane kukuba yiyo le nto kufuneka silumke kakhulu malunga nokusebenzisa iPVC, nokuba - ngakumbi xa! Kodwa ngendlela esizibophelele ngayo ukugcina okusingqongileyo kukhuselekile kwaye kwangaxeshanye senze ukuba kube nokwenzeka ukusetyenziswa kweplastiki ngazo zonke iintlobo zokulula ezineempawu ezifana nezinye iikhompawundi azithandi ukudibanisa!
