Ukuba ufikile kweli phepha, mhlawumbi uqhelene nokuba zeziphi iigumboots kunye nesidingo somgangatho ophezulu, iibhutsi ezingenamanzi.Kodwa, ukhe uyeke ukucinga, zenziwe ngantoni iibhutsi zemvula? Ewe, uninzi lweebhutsi ezingenamanzi zenziwe ngerabha yendalo okanye i-polyvinyl chloride - imathiriyeli eyenziweyo eyaziwa ngokuba yiPVC okanye ivinyl.
Irabha yendalo ivela kwilatex (sap) yomthi werabha (Yiba brasiliensis) ekhula kwihlabathi jikelele kwizityalo zetropikhi ezifana neBrazil, Thailand, neIndonesia.I-PVC, kwelinye icala, luhlobo lweplastiki eyenziwe kwilebhu kwaye ithathwe kwi-petroleum.Kukho okuhle kunye nokungalunganga ekusebenzeni ngento esekwe kwindalo okanye into eyenziweyo njengoko imathiriyeli nganye ibonelela ngento eyahlukileyo ngokumalunga nomgangatho, ukuqina, ubunzima, kunye nokufikeleleka.
Okokuqala, makhe sithethe ngerabha yendalo!Zonke i-Merry People gumboots zenziwe ngerabha yendalo yangaphandle kunye neyodwa.Ukuguqulwa ukusuka kwi-latex ukuya kwirabha (kwaye emva koko ibe yi-gumboots yakho), i-latex yendalo ingena kwi-vulcanisation, inkqubo ephuhliswe kwaye inikwe ilungelo elilodwa lomenzi nguCharles Goodyear waseGoodyear tyres.I-Vulcanisation iyacaphukisa irabha kwaye iyivumela ukuba ibunjwe ngokulula kwezinye iimilo.Ukusuka apho, i-die-iphoswe kwiimilo ezigobileyo zeebhutsi.Le yinkqubo yokuvelisa ixesha elide kuneendlela ezisetyenziswayo ekwenzeni iigumboots zePVC, kodwa isiphumo sikumgangatho ophezulu wokugquma, ukuthamba, kunye nokusebenza kokuchasana nomhlwa.
Ukomelela, ukuqina, kunye nomgangatho werabha yendalo iza kunye norhwebo kubunzima kunye neendleko.Ngokwendalo yayo, irabha yinto enzima kunePVC, oku kuthetha ukuba iigumboots zerubha zendalo zinzima kune-PVC gumboots.Umsebenzi wezandla obandakanyekayo ekucofeni i-latex kumthi werabha kunye nokuwulungisa ube yirabha nawo ubiza kakhulu kuneenkqubo ezibandakanyekayo ekwenzeni i-PVC.Oku kuthetha ukuba iigumboots zerubha zendalo zibiza kakhulu kunePVC gumboots.Kukho, nangona kunjalo, i-tradeoff emele yenziwe njengexabiso eliphezulu lokuqala lerabha yendalo ehlala ixesha elide ihlawulwe kubomi obude bezinto eziphathekayo njengoko iibhutsi zakho zingayi kufuna ukutshintshwa rhoqo.Sikholelwa ngamandla kwixabiso elisemva kokuqina kunye nokuvavanya iindleko-nganye-ukunxiba kweegumboots zakho kwaye simela oku ngewaranti yonyaka omnye kwiibhutsi zethu.
Ngoku makhe sithethe ngePVC!I-PVC yiplastiki ekhaphukhaphu eyenziweyo eyenziwe, ngokuyinxenye, kwipetroleum.Ukudala iPVC yinkqubo entsonkothileyo ebandakanya iikhemistri ezininzi, kodwa ngoku ikwayinkqubo ethandwa kakhulu nengabizi kakhulu esetyenziswa kuluhlu olubanzi lwamashishini.Ukuguqula i-PVC ibe ziibhutsi, iipellet ezincinci zePVC ziyanyibilika zibe lulwelo, emva koko zigalelwe malunga nokungunda kwebhutsi kwinkqubo ebizwa ngokuba yinaliti-yokubumba.Isitofu sokubumba sisetyenziselwa uluhlu lweeprojekthi, okwenza kube yinkqubo engabizi kakhulu yokwenza kwaye yenza iibhutsi ze-PVC zibe yindleko ephantsi yokhetho lokukhusela amanzi kunye nabo bafuna iibhutsi ezinobunzima obulula.
