Ho kwalwa ha Phenolic le Urea ka Khoele e Tswelang Pele
Thepa e ka sehloohong ea litiiso tsa phenolic ke resin ea phenolic, e leng polasetiki ea thermosetting e tsebahalang ka ho hanyetsa mocheso le matla a eona. Ka lehlakoreng le leng, litiiso tsa urea li entsoe ka resin ea urea formaldehyde, e nang le litšobotsi tse tšoanang empa li fapane hanyane le litiiso tsa phenolic.
Mefuta ena ka bobedi ya ho kwala e entswe ka dikhoele tse tswelang pele ho netefatsa hore e lekana hantle molaleng o tsamaellanang le setshelo, e leng se thusang ho buleha le ho kwala. Mokgwa ona wa ho kwala dikhoele o fana ka tiiso e tshepahalang ho thibela ho dutla kapa ho silafala ha dikahare tse ka hara setshelo.
1. Thepa: Litiiso hangata li etsoa ka li-resin tsa phenolic kapa urea
2. Sebopeho: Ho kwala hangata ho ba sedikadikwe ho lekana moralo wa molala wa dijana tse fapaneng. Sekwahelo hangata se na le ponahalo e boreledi. Dikarolo tse ding tse itseng tsa ho kwala di na le masoba hodimo mme di ka kopanngwa le diaphragm kapa didropper bakeng sa tshebediso.
3. Litekanyo: "T" Tekanyo (mm) - 8mm/13mm/15mm/18mm/20mm/22mm/24mm/28mm, "H" Tekanyo ka lisenthimithara - 400 Qetello/410 Qetello/415 Qetello
4. Sephutheloana: Hangata dikoalo tsena di etswa ka tlhahiso e kgolo mme di kentswe ka mabokoseng a khateboto a sa senyeheng tikoloho ho netefatsa polokeho nakong ya dipalangwang le polokelo.
Har'a litiiso tsa phenolic le urea tse nang le khoele e tsoelang pele, litiiso tsa phenolic hangata li sebelisa resin ea phenolic e le thepa e tala ea mantlha, ha litiiso tsa urea li sebelisa resin ea urea formaldehyde. Lisebelisoa tse tala tse ka bang teng li ka kenyelletsa lintho tse eketsang, mebala le li-stabilizer ho ntlafatsa botsitso bohle ba thepa.
Ts'ebetso ea rona ea tlhahiso bakeng sa litiiso tsa phenolic le urea tse nang le khoele e tsoelang pele e kenyelletsa ho kopanya thepa e tala - resin e ntle ea phenolic kapa urea e kopantsoeng le lintho tse ling tse tlatsetsang ho etsa motsoako o hlokahalang bakeng sa litiiso; Ho theha - ho kenya motsoako ka har'a hlobo ka mekhoa e kang ho enta ka ente kapa ho enta ka khatello, le ho sebelisa mocheso o loketseng le khatello ho e bopa hore e be karolo e koetsoeng kamora ho e etsa; Ho Pholisa le ho Folisa - Ho koala ho entsoeng ho hloka ho pholisoa le ho phekoloa ho netefatsa hore ho koala ho ka boloka sebopeho le sebopeho se tsitsitseng; Ho sebetsana le ho Penta - Ho latela litlhoko tsa bareki kapa tsa tlhahiso, likarolo tse koetsoeng li ka hloka ho sebetsoa (joalo ka ho tlosa li-burrs) le ho penta (joalo ka ho koahela likarolo tse sireletsang).
Lihlahisoa tsa rona li tlameha ho feta litekong tse tiileng tsa boleng ho netefatsa hore lihlahisoa tsohle li latela maemo le melawana e amehang. Lintho tsa liteko li kenyelletsa tlhahlobo ea boholo, tlhahlobo ea sebopeho, tlhahlobo ea boreledi ba bokaholimo, tlhahlobo ea ts'ebetso ea ho tiisa, jj. Tlhahlobo ea pono, tlhahlobo ea ts'ebetso ea 'mele, tlhahlobo ea lik'hemik'hale le mekhoa e meng e sebelisoa bakeng sa tlhahlobo ea boleng.
Dikarolo tsa ho kwala tseo re di hlahisang hangata di phuthelwa ka bongata bakeng sa ho tsamaisa le ho boloka habonolo. Re sebedisa mabokose a khateboto a mosa tikolohong bakeng sa ho paka, a kwahetsweng kapa a manehilweng ka thepa e thibelang ho wa le ho hanela tshisinyeho ya lefatshe, ka mekhahlelo e mengata ya mehato ya tshireletso ho thibela tshenyo le ho fetoha ha dibopeho.
Ho fana ka tšebeletso e khotsofatsang ka mor'a thekiso ho bareki ke karolo ea bohlokoa. Re fa bareki ba rona litšebeletso tse felletseng, ho kenyeletsoa le pele ho thekiso, thekisong, le lits'ebeletsong tsa kamora thekiso. Haeba bareki ba na le lipotso mabapi le boleng, ts'ebetso, kapa mathata a mang a litiiso tsa rona, ba ka ikopanya le rona inthaneteng, ka imeile, kapa mekhoa e meng. Re tla araba kapele 'me re fane ka litharollo.
Ho bokella maikutlo a bareki khafetsa ke tsela ea bohlokoa ea ho ntlafatsa lihlahisoa le ho qapa tlhahiso. Re boetse re amohela basebelisi bohle ho re fa maikutlo a utloahalang mabapi le lihlahisoa tsa rona neng kapa neng, e leng se tsamaellanang le maikutlo a bareki. Re tla ntlafatsa ts'ebetso ea rona ea tlhahiso. Re tsoela pele ho fetola le ho ntlafatsa boleng ba tlhahiso le tšebeletso ea kamora thekiso ho fihlela litlhoko le litebello tsa bareki.
