Isikhumba sePVC sisixhobo sokwenziwa, ekwabizwa ngokuba sisikhumba sokwenziwa okanye ukulinganisa. Yenziwe nge-polyvinyl chloride (PVC) resin kunye nezinye izongezo ngokusebenzisa uthotho lweendlela zokulungisa, kwaye inenkangeleko efana nesikhumba kunye nokuziva. Nangona kunjalo, xa kuthelekiswa nesikhumba sokwenyani, isikhumba sePVC sinobuhlobo ngakumbi nendalo esingqongileyo, kulula ukusicoca, siyakwazi ukunxiba, kwaye siyamelana nemozulu. Ke ngoko, isetyenziswe ngokubanzi kwifenitshala, iimoto, iimpahla, iibhegi kunye namanye amasimi.
Okokuqala, izinto ezikrwada zesikhumba se-PVC ikakhulu yi-polyvinyl chloride resin, into eqhelekileyo yeplastiki eneplastiki elungileyo kunye nokumelana nemozulu. Xa usenza ngesikhumba PVC, ezinye izinto ezincedisayo ezifana plasticizers, stabilizers, fillers, kwakunye pigments kunye neearhente yonyango umphezulu zongezwa ukwenza izitayile ezahlukeneyo kunye nokusebenza izinto zesikhumba PVC ngokuxuba, calendering, ukutyabeka kunye nezinye iinkqubo.
Okwesibini, isikhumba sePVC sineenzuzo ezininzi. Okokuqala, inkqubo yayo yokuvelisa ilula kwaye ixabiso liphantsi, ngoko ke ixabiso liphantsi, elinokuthi lihlangabezane neemfuno zokusetyenziswa kobuninzi. Okwesibini, iPVC yesikhumba inokumelana nokunxiba kakuhle kunye nokumelana nemozulu, akukho lula ukuguga okanye ukonakala, kwaye inobomi obude benkonzo. Okwesithathu, iPVC yesikhumba kulula ukuyicoca, kulula ukuyigcina, akukho lula ukuyicoca, kwaye kulula ukuyisebenzisa. Ukongeza, i-PVC yesikhumba nayo ineempawu ezithile zokungangeni manzi, ezinokuxhathisa ukhukuliseko lwamanzi ukuya kumlinganiselo othile, ngoko ke iye yasetyenziswa ngokubanzi kwezinye iimeko ezifuna iipropati ezingenamanzi.
Nangona kunjalo, isikhumba sePVC sikwanazo ezinye izinto ezingalunganga. Okokuqala, xa kuthelekiswa nesikhumba sokwenyani, i-PVC yesikhumba inomoya omdaka kwaye ithanda ukungakhululeki ngexesha lokusetyenziswa kwexesha elide. Okwesibini, ukukhuselwa kokusingqongileyo kwesikhumba sePVC kukwaphikisana, kuba izinto ezinobungozi zinokukhutshwa ngexesha lokuvelisa kunye nokusetyenziswa, okuya kuchaphazela indalo kunye nempilo yabantu.
Okwesithathu, ufele lwePVC luneplastikhi emdaka kwaye akukho lula ukwenza izinto ezintsonkothileyo ezinemigangatho emithathu, ngoko ke iyasikelwa umda kwezinye iimeko zesicelo esikhethekileyo.
Ngokubanzi, isikhumba se-PVC, njengento yokwenziwa, isetyenziswe ngokubanzi kwifenitshala, iimoto, iimpahla, iibhegi kunye namanye amasimi. Iinzuzo zayo ezifana nokunganyangeki, ukumelana nemozulu kunye nokucocwa ngokulula kwenza ukuba kuthathelwe indawo yesikhumba sangempela. Nangona kunjalo, iintsilelo zayo ezifana nokungangeni kakuhle komoya kunye nokukhuselwa kokusingqongileyo okuthandabuzekayo kufuna ukuba sinikele ingqalelo xa siyisebenzisa, kwaye sikhethe izinto ezifanelekileyo ukuhlangabezana neemfuno ezahlukeneyo.
