Ukongeza, izinto ezingezizo eze-PVC ngokubanzi zinomngcipheko omncinci wokuvelisa iimveliso ezineengxaki, ngaloo ndlela zinciphisa inkunkuma kwaye zonyusa ukusebenza kakuhle ngokubanzi.

3. Umgangatho kunye nokuqina:Izixhobo ezingezizo eze-PVC ezisetyenziswa kwezi ndlela zemveliso zaziwa ngomgangatho wazo ophezulu kunye nokuqina kwazo. Zibonelela ngokumelana okuhle kweekhemikhali, ziqinisekisa ukuba umxholo ongaphakathi kwiingxowa awuchaphazeleki. Ngaphezu koko, iingxowa ezingezizo eze-PVC zibonisa amandla aphezulu kunye nokumelana nokubhoboza, nto leyo enegalelo ekubeni zihlale ixesha elide kwaye zisebenze ngokuthembekileyo.

4. Ixabiso elifanelekileyo:Nangona utyalo-mali lokuqala kumgca wemveliso yeengxowa ezithambileyo ezingeyo-PVC lunokuba phezulu kunemigca yesiqhelo ye-PVC, iingenelo zeendleko zexesha elide zinkulu. Ngobuchule obukhulu bokusebenza kunye nenkunkuma encinci, le migca yemveliso inokukhokelela ekongeni okukhulu ngokuhamba kwexesha.

Ngaphezu koko, njengoko imithetho ephathelele ukusetyenziswa kwePVC iqina kwaye imfuno yabathengi yeemveliso ezinobuhlobo nokusingqongileyo isanda, amashishini atyala imali kwitekhnoloji engeyiyo iPVC anokuzifumana ekwimeko engcono yokuphepha izohlwayo ezinokubakho kunye nokuhlangabezana neemfuno zemarike.

Imigca yemveliso yeengxowa ezithambileyo ezingezizo zePVCzibonelela ngeenzuzo ezahlukeneyo ezizenza zibe lukhetho olunomtsalane kumashishini afuna ukuphucula indlela asebenza ngayo, ukuphucula ukusebenza kakuhle, ukubonelela ngeemveliso ezisemgangathweni ophezulu, kunye nokufezekisa ukonga imali.
