Inokuba yenzekile kuthi sonke ngamanye amaxesha: bayasithengisela ihagu ngomvundla kwaye sihlala sivalelwe kubuxoki ngaphandle kokwazi kude kube mva, xa ezo zihlangu zathembisa ngesikhumba esomeleleyo ziqala ukuba buthathaka. Okanye ukugqitywa kwesinyithi okuqhelekileyo kuhanjiswe ngokunyuka okanye ezimbini.
Unokuziva uzolile! Yinto eqhelekileyo kwaye ayenzeki kuwe kuphela. Kunzima ukwahlula ukusebenza kwezinto ezithile, uhlobo lolwakhiwo kunye nomgangatho weembadada ngaphandle kwamehlo ezonyango. Umntu kufuneka athathe ikhosi esisiseko ukuze umntu afunde izihlangu ngaphambi kokuba azithenge kodwa kuya kuba kuninzi, akunjalo? Kodwa ubuncinci sinokuthi siqwalasele iimpawu zezinto ezithile zokuvelisa ezinokuthi, ukuba zikumgangatho ophantsi, zibe yintlekele ethile.
Elinye lala matyala lelo isikhumba selungelo elilodwa lomenzi, Izinto ezinokubonakala zinobunkunkqele ukuba zikumgangatho okanye zinqamleza umhlaba xa ujongeka ngathi uplastikhi. Imfihlo yesikhumba selungelo elilodwa lomenzi ikwinkqubo yokuvelisa. Masibone:
Patent yesikhumba ayikho enye into ngaphandle isikhumba esidityaniswe nge-varnish okanye i-lacquer. Yonke into ukufezekisa indawo ebonakalayo kunye nebengezelayo. Ivanishi inokuba nombala kwaye kuqhelekile ukuba neoyile yemifuno, izinto ezivela kwiselulosic, kunye neemveliso zokwenziwa ezifana neplastiki. Kodwa kukwakho nenye imfuneko, ukuze izinto ezo zihlelwe njenge Ipatent yesikhumba enamathela kufuneka ibe nobukhulu obungadluli ku-0,15 mm.
Xa la manyathelo angahlonitshwa kuxa ezo zihlangu zibonakala kwindawo ekude kakhulu nolusu oluthambileyo lobunikazi. Iyenzeka kuba endaweni ye-lacquer okanye i-varnish a iphepha leplastiki esele yenziwe, ihlala i-PVC kwaye ukongeza umda we-0,15 mm ugqityiwe, eyona nto iphambili xa kufikwa ekunikezeleni ukutya okumnandi.
Okokugqibela, kukwakho elaminethiweyo patent yesikhumba, Sisikhumba esigqunywe ngephepha leplastikhi elingaphezulu kwe-0,15 mm kodwa lona lingaphantsi kwesiqingatha sobunzima bezinto ezigqityiweyo.
