Litharollo tsa Tanka ea Metsi ea PVC li Thusa Ntlafatso e Ntle ea Indasteri
Lits'ebetsong tsa morao-rao tsa indasteri le tsa bolulo, khetho ea lisebelisoa tsa polokelo ea metsi e ama ka kotloloho botsitso le polokeho ea sistimi. Litanka tsa metsi tsa PVC, tse hanyetsanang le kutu, moralo oa tsona o bobebe, ho tšoarella, le litšenyehelo tse theko e tlase, li fetohile tharollo e ratoang maemong a mangata. Leha ho le joalo, moralo oa mahlale, ho kenya ts'ebetso e nepahetseng, le tlhokomelo e sebetsang ea litanka tsa metsi tsa PVC e ntse e le litaba tsa bohlokoa tsa indasteri. Sengoliloeng sena se hlahloba litharollo tse felletseng bakeng sa litanka tsa metsi tsa PVC ho tsoa mahlakoreng a mararo: thepa ea thepa, maemo a ts'ebeliso, le maano a ho ntlafatsa.
PVC (polyvinyl chloride) e na le khanyetso e ntle ea lik'hemik'hale, e hanela ho bola ho tsoa mefuteng e mengata ea metsi a asiti le a alkaline. E loketse polokelo ea metsi makaleng a nosetso a lik'hemik'hale, tikoloho le temo. Ho feta moo, boima ba eona ke feela-e leng karolo ea bohlano ea litanka tsa tšepe, e leng ho fokotsang ho rarahana ha lipalangoang le ho kenya. Haholo-holo{4}e loketse lisebelisoa tse bobebe tse kang litanka tse marulelong le polokelo ea metsi ea nakoana. Ntle le moo, bokahare bo boreleli ba litanka tsa metsi tsa PVC bo hanela kholo ea baktheria, ho kopana le litekanyetso tsa bohloeki ba metsi a nooang le ho fumana ts'ebeliso e atileng lits'ebetsong tsa phepelo ea metsi.
Litharollo tsa litanka tsa metsi tsa PVC li hloka meralo e fapaneng bakeng sa maemo a fapaneng a ts'ebeliso. Ka mohlala, libakeng tse phahameng-mocheso, PVC e fetotsoeng e nang le matla a matla a ho thibela mocheso e ea hlokahala ho thibela ho senyeha ho bakoang ke ho ba letsatsing nako e telele. Libakeng tsa indasteri tse nang le li-acids tse matla le li-alkalis, liphanele tse teteaneng kapa liphahlo tse khethehileng lia hlokahala ho matlafatsa khanyetso ea kutu. Ho kenya hape ho bohlokoa; ho bata ha motheo, matla a sebopeho sa tšehetso, le ho tiea ha likhokahanyo tsa lipeipi kaofela li ama bophelo ba tanka ea metsi ka kotloloho. Lihokelo tse feto-fetohang lia khothaletsoa, 'me mehato ea thibelo ea ho lutla manonyeletsong e lokela ho hlahlojoa khafetsa.
Ho hloekisa khafetsa le ho bolaea likokoana-hloko ke senotlolo sa ho netefatsa boleng ba metsi. Bakeng sa litanka tse bolokang metsi a tloaetseng ho ruruha ka nako e telele, ho ka eketsoa lisebelisoa tse bakang tsitsipano kapa li-valve tsa ho ntša metsi ho fokotsa ho bokellana ha sediment. Ho feta moo, basebelisi ba lokela ho theha sistimi ea kamehla ea tlhahlobo, e shebaneng le ho peperana ha manonyeletso le ho senyeha ha lera la tšireletso la UV, le ho kenya tšebetsong litokiso kapa tse ling hang hang.
Ka tsoelo-pele ea mahlale a thepa, litanka tsa metsi tsa PVC li tla tsoela pele ho fetoha ho isa boima bo bobebe le theknoloji e bohlale. Libapali tsa indasteri li hloka ho tsoela pele ho ntlafatsa litharollo tsa meralo le ho fana ka lits'ebeletso tse ikhethileng tse tsamaellanang le litlhoko tsa basebelisi, ka ho etsa joalo li khothaletse ts'ebetso, polokeho le nts'etsopele e tsitsitseng ea lisebelisoa tsa polokelo ea metsi.
