Lefatše - Hexamethylenetetramine ea Pele: K'hemik'hale ea Bohlokoa Mabaleng a Liindasteri a Fapaneng
Masimo a Maholo a Kopo
Indastering ea meriana, hexamethylenetetramine e phetha karolo ea bohlokoa. E sebelisoa e le moemeli oa antiseptic merianeng e meng ea moroto. Ha e nooa, e senyeha tikolohong ea asiti ea moroto ho lokolla formaldehyde, e nang le thepa ea antibacterial. Sena se thusa ho thibela le ho phekola tšoaetso ea moroto ka ho thibela kholo ea libaktheria tse kotsi. Likhamphani tsa meriana li itšetleha ka hexamethylenetetramine ea rona ea boleng bo holimo ho hlahisa meriana e sebetsang e fanang ka phomolo ho bakuli ba nang le mathata a moroto.
Indasteri ea rabara e rua molemo haholo ho Hexamethylenetetramine ea rona ea Lefatše ka Bophara. E sebetsa e le se potlakisang ts'ebetso ea ho etsa rabara e be matla haholoanyane. Ho etsa rabara e be matla ke ts'ebetso e fetolang rabara e tala hore e be thepa e tšoarellang le e tenyetsehang haholoanyane ka ho kopanya liketane tsa eona tsa polymer ka sefapano. Hexamethylenetetramine e potlakisa karabelo ena ea ho kopanya e kopaneng, e fokotsa nako le matla a hlokahalang bakeng sa ho etsa rabara e be matla. Bahlahisi ba rabara ba ka hlahisa lihlahisoa tsa rabara tsa boleng bo holimo, tse kang mabili, mabanta a tsamaisang thepa, le litiiso, ka katleho e kholo ka tšebeliso ea hexamethylenetetramine ea rona. Sena ha se ntlafatse feela tlhahiso ea ts'ebetso ea tlhahiso empa hape se ntlafatsa ts'ebetso le bophelo ba lihlahisoa tsa rabara tsa ho qetela.
Indastering ea resin le polasetiki, hexamethylenetetramine ke motsoako oa bohlokoa. E sebelisoa tlhahisong ea li-resin tsa phenolic. Li-resin tsa phenolic li sebelisoa haholo lits'ebetsong tse kang ho kenya mocheso ka motlakase, likhomaretsi le metsoako. Hexamethylenetetramine e sebetsa e le moemeli oa ho folisa li-resin tsa phenolic, e khothalletsa ho thehoa ha sebopeho sa marang-rang a mahlakore a mararo. Sena se fella ka li-resin tse nang le khanyetso e ntle ea mocheso, matla a mechini le botsitso ba lik'hemik'hale. Bahlahisi ba resin le polasetiki ba ka etsa lihlahisoa tse sebetsang hantle tse fihlelang litlhoko tse hlokoang tsa liindasteri tse fapaneng, ho kenyeletsoa lisebelisoa tsa elektroniki, likoloi le kaho, ka ho sebelisa hexamethylenetetramine ea rona.
Indastering ea ts'ebetso ea tšepe, hexamethylenetetramine ea rona e sebelisoa e le thibelo ea ts'enyeho. E etsa filimi e sireletsang holim'a litšepe, e thibelang oxidation le ts'enyeho. Sena se bohlokoa haholo lits'ebetsong moo litšepe li pepesehelang tikoloho e thata, joalo ka indastering ea oli le khase, lits'ebetsong tsa leoatleng le mechini ea indasteri. Ka ho sebelisa li-inhibitor tsa ts'enyeho tse thehiloeng ho hexamethylenetetramine, lik'hamphani tsa ts'ebetso ea tšepe li ka eketsa bophelo ba likarolo tsa tsona tsa tšepe, tsa fokotsa litšenyehelo tsa tlhokomelo, le ho ntlafatsa ts'epo ea lisebelisoa tsa tsona.

Ka kakaretso
Hexamethylenetetramine ea rona ea Lefatše ka Bophara e pakiloe ka har'a lijana tsa boleng bo holimo, tse sa keneng moeeng ho thibela ho senyeha leha e le hofe nakong ea polokelo le lipalangoang. Sehlopha se seng le se seng se feta mehatong e matla ea taolo ea boleng, ho kenyeletsoa liteko tsa bohloeki, tlhahlobo ea lik'hemik'hale le litekolo tsa ts'ebetso. Hore na u k'hamphani ea meriana Amerika Leboea, moetsi oa rabara Asia, moetsi oa resin le polasetiki Europe, kapa feme ea ts'ebetso ea tšepe Afrika, hexamethylenetetramine ea rona ke tharollo e tšepahalang le e feto-fetohang eo u e hlokang. E fana ka ts'ebetso e ke keng ea bapisoa, e netefatsa hore e fihlela le ho feta litlhoko tsa hau tse ikhethileng tsa indasteri.
