Uma uze kuleli khasi, cishe uyazi ukuthi ayini ama-gumboots nesidingo sekhwalithi ephezulu, amabhuzu angangeni manzi.Kodwa, uke wema ukuze ucabange, enziwa ngani amabhuzu emvula? Nokho, amabhuzu amaningi angangeni manzi enziwa ngerabha yemvelo noma i-polyvinyl chloride - into yokwenziwa eyaziwa ngokuthi i-PVC noma i-vinyl.
Irabha yemvelo ivela ku-latex (sap) yesihlahla senjoloba (I-Havea brasiliensis) ekhula emhlabeni jikelele ezindaweni ezishisayo ezifana neBrazil, Thailand, ne-Indonesia.I-PVC, ngakolunye uhlangothi, iwuhlobo lwepulasitiki olwakhiwe elebhu futhi lususelwa ku-petroleum.Kunobuhle nobubi ekusebenzeni ngento esekwe emvelweni noma yokwenziwa njengoba impahla ngayinye ihlinzeka ngokuthile okuhlukile mayelana nekhwalithi, ukuqina, isisindo, kanye nokuthengeka.
Okokuqala, ake sixoxe ngenjoloba yemvelo!Wonke ama-Merry People gumboots enziwe ngerabha yemvelo yangaphandle neyodwa.Ukuze iguqulwe isuka ku-latex ibe irabha (bese ibe yizicucu zakho), i-latex yemvelo iba sengozini, inqubo eyakhiwe futhi yagunyazwa ubunikazi bamathayi ka-Charles Goodyear we-Goodyear.I-Vulcanisation ithulisa irabha futhi iyivumele ukuthi ibunjwe kalula ibe ezinye izimo.Ukusuka lapho, iphonswa i-die-cast ibe yizimo ezigobile zamabhuzu.Lena inqubo yokukhiqiza ende kunezindlela ezisetshenziswa ekwenzeni ama-gumboots e-PVC, kodwa umphumela uwukugqumisa kwekhwalithi ephezulu, ukuthamba, nokusebenza kokunqanda ukugqwala.
Ukuqina, ukunwebeka, kanye nekhwalithi yerabha yemvelo kuhambisana nokuhwebelana ngesisindo nezindleko.Ngokwemvelo yayo, irabha iwumsebenzi osindayo kune-PVC, okusho ukuthi amagumboothi erabha emvelo asinda kunama-gumboots e-PVC.Umsebenzi wezandla ohilelekile ekubanjeni i-latex esihlahleni senjoloba nokuyicubungula ibe yinjoloba nawo ubiza kakhulu kunezinqubo ezihilelekile ekwenzeni i-PVC.Lokhu kusho ukuthi ama-gumboots erabha emvelo ngokuvamile abiza kakhulu kune-PVC gumboots.Kukhona, nokho, ukuhwebelana okuzokwenziwa njengoba izindleko eziphezulu zokuqala zenjoloba yemvelo ehlala isikhathi eside ikhokhwa ngokuphila isikhathi eside kwempahla njengoba amabhuzu akho engeke adinge ukushintshwa njalo.Sikholelwa ngokuqinile enanini lokuqina kanye nokuhlola izindleko zokugqoka ngakunye kwama-gumboots akho futhi simelana nalokhu ngewaranti yonyaka owodwa kumabhuzu ethu.
Manje ake sikhulume ngePVC!I-PVC iyipulasitiki yokwenziwa engasindi ekhiqizwa, ngokwengxenye, nge-petroleum.Ukudala i-PVC kuyinqubo eyinkimbinkimbi ehilela amakhemikhali amaningi, kodwa futhi manje kuyinqubo edume kakhulu futhi engabizi kakhulu esetshenziswa ezimbonini eziningi.Ukuguqula i-PVC ibe amabhuzu, ama-pellets amancane e-PVC ayancibilika abe uketshezi, bese athululelwa eduze kwesikhunta sebhuthi ngenqubo ebizwa ngokuthi umjovo-ukubumba.Ukubumba umjovo kusetshenziselwa uxhaxha lwamaphrojekthi, okwenza kube inqubo engabizi kakhulu yokwenza futhi kwenza amabhuzu e-PVC abe inketho ethandwayo engabizi kakhulu yokuvimbela amanzi kanye nalabo abafuna amabhuzu anesisindo esincane.
