Mokhoa oa ho kopanya oa pipe ea mollo: khoele, groove, flange, joalo-joalo Pipe ea tšepe e ka hare le e ka ntle ea epoxy bakeng sa tšireletso ea mollo ke phofshoana e boima e fetotsoeng e khahlanong le kutu epoxy resin powder, e nang le lik'hemik'hale tse ntle haholo tsa ho hanyetsa.Ha e le hantle e rarolla mathata a mangata a kang mafome a holim'a mafome le ho eketseha ha lerako la ka hare la lihlahisoa tse tšoanang ka mor'a tšebeliso ea nako e telele, e le ho qoba ho thibela ka hare ho ama ts'ebeliso, e le ho ntlafatsa haholo bophelo ba tšebeletso ea liphaephe tse khethehileng tse thibelang mollo.Ka lebaka la ho eketsoa ha lisebelisoa tse thibelang lelakabe lihlahisoa tsa ho roala, ho hanyetsa mocheso oa sehlahisoa ho ntlafatsoa ha ho bapisoa le lihlahisoa tse ling tse tšoanang.Ka hona, e ke ke ea ama ts'ebeliso ha mocheso oa tikoloho o phahama haholo.Bophelo ba ts'ebeletso le ts'ebetso ea liphaephe tsa mollo tse koahetsoeng ka hare le ka ntle li molemo haholo ho feta tsa liphaephe tse entsoeng ka masenke.Mmala o mokgubedu.

Fektheri ea rona e sebetsa ka ho khetheha ho hlahisa phala ea mollo, phala ea tšepe e entsoeng ka masenke, phala ea ho roala phofo, phala ea ho roala phofo le phala ea tšepe ea 6-inch.Kopo: phepelo ea metsi a mollo, phepelo ea khase le tsamaiso ea lipeipi tsa lipalangoang tse mahareng tsa foam.Boleng ba sehlahisoa bo feta litloaelo mme bo feta liteko tse ngata pele bo tloha fekthering.Ikamahanye le maemo a boleng ba naha le ba machabeng.

(1) Lintho tse phahameng tsa mechine.Epoxy resin e na le momahano e matla le sebopeho sa limolek'hule tse teteaneng, ka hona, thepa ea eona ea mochini e phahame ho feta li-resin tse akaretsang tsa thermosetting joalo ka phenolic resin le polyester e sa tsitsang.

(2) Ho roala ha pipe ea mollo e koahetsoeng ka polasetiki ho nka epoxy resin, e nang le sekhomaretsi se matla.Sistimi ea pheko ea epoxy resin e na le sehlopha sa epoxy, sehlopha sa hydroxyl, bond ea ether, bond ea amine, bond ea ester le lihlopha tse ling tsa polar tse nang le ts'ebetso e kholo, e fanang ka lihlahisoa tse phekotsoeng tsa epoxy ho khomarela tšepe, lirafshoa, khalase, konkreite, lehong le likarolo tse ling tsa polar.

(3) Ho fokotseha ho honyenyane ho phekola.Ka kakaretso 1% ~ 2%.Ke e 'ngoe ea mefuta e nang le shrinkage e nyenyane ka ho fetisisa ea ho folisa har'a li-resin tsa thermosetting (phenolic resin ke 8% ~ 10%; unsaturated polyester resin ke 4% ~ 6%; silicone resin ke 4% ~ 8%).Mohala oa katoloso ea mohala o boetse o nyane haholo, ka kakaretso ke 6 × 10-5/℃。 Ka hona, molumo o fetoha hanyane kamora ho folisa.

(4) Mosebetsi o motle.Epoxy resin ha e le hantle ha e hlahise limolek'hule tse fokolang nakong ea phekolo, kahoo e ka thehoa tlas'a khatello e tlaase kapa khatello ea ho kopana.E ka sebelisana le lisebelisoa tse fapaneng tsa ho phekola ho hlahisa liphahlo tse lumellanang le tikoloho joalo ka tse se nang solvent, tse tiileng haholo, tse nang le phofo le liphahlo tse thehiloeng metsing.

(5) Motlakase o motle ka ho fetisisa.Epoxy resin ke resin ea thermosetting e nang le thepa e ntle ea antistatic.

(6) Botsitso bo botle le khanyetso e ntle ea lik'hemik'hale.Epoxy resin ntle le alkali, letsoai le litšila tse ling ha ho bonolo ho senyeha.Hafeela e bolokiloe hantle (e tiisitsoe, e se na mongobo le mocheso o phahameng), nako ea polokelo ke 1 selemo.Kamora letsatsi la ho felloa ke nako, haeba tlhahlobo e tšoaneleha, e ntse e ka sebelisoa.Motsoako oa pheko oa epoxy o na le botsitso bo botle ba lik'hemik'hale.Ho hanyetsa ho bola ha eona ho alkali, asiti, letsoai le mecha e meng ea litaba ho molemo ho feta ea resin ea unsaturated polyester, resin ea phenolic le li-resin tse ling tsa thermosetting.Ka hona, epoxy resin e sebelisoa haholo e le anti-corrosion primer.Hobane epoxy resin e phekotsoeng e na le sebopeho sa marang-rang a mahlakore a mararo 'me e khona ho hanela ho kenngoa ha oli, e sebelisoa haholo leboteng la ka hare la litanka tsa oli, litanka tsa oli le lifofane.
