Tlhokahalo e ntseng e Hola ea Li-resin tsa Polyester tse Unsaturated ho Cooling Tower Spray Hand Lay-Up applications.

tsebisa:

Ha indasteri ea kaho e ntse e hola, tlhoko ea li-polyester resin tse sa sebetseng e ntse e eketseha. Li-resin tsena li bapala karolo ea bohlokoa tlhahisong ea lihlahisoa tse fapaneng joalo ka litora tse pholileng le litanka tsa polokelo mme li sebelisoa haholo lits'ebetsong tse fapaneng tsa indasteri. Ho blog ena, re tla teba ka botebo ka bohlokoa ba li-resine tsa polyester tse sa tsitsang, re shebane le ts'ebeliso ea tsona ho lay-up ea tora ea jet e phodileng. Feme ea rona ea Chaena ke moetapele oa ho fana ka li-resin tsa polyester tsa boleng bo holimo bakeng sa morero ona. Joaloka molekane oa hau ea tšepahalang oa khoebo, re ikemiselitse ho fana ka tharollo e molemohali bakeng sa litlhoko tsa hau.

Ho beha letsoho ka letsoho la polyester resin ea unsaturated toreng e pholileng:

Sebapali se ka sehloohong sebakeng sena ke resin ea rona ea Ortho-type unsaturated polyester e tsejoang e le 115PT. Viscosity ea eona e mahareng le reactivity e phahameng e e etsa khetho ea pele bakeng sa lisebelisoa tsa ho beha letsoho tsa tora ea ho pholisa. Resin e na le matla a matla a mochini, ho hanyetsa mocheso hantle le thepa ea ho folisa ka potlako. Litšobotsi tsena li e etsa thepa e loketseng bakeng sa tlhahiso ea litora tse pholileng, litanka tsa polokelo, le lihlahisoa tse ling tsa polasetiki tse matlafalitsoeng ka fiberglass (FRP). Nako ea bophelo ea resin ke likhoeli tse 6. E pakiloe ka moqomong oa tšepe 'me e lokela ho bolokoa sebakeng se nang le moea ho qoba khanya ea letsatsi, mocheso le mollo.

Keketseho ea tšebeliso ea kaho:

Ka lebaka la litšoaneleho tsa tlhaho tsa li-resin tsa polyester tse sa sebetseng, ts'ebeliso ea indasteri ea kaho e eketsehile haholo. Li-resin tsena li fana ka ts'ebetso e ntle ea ho hanyetsa kutu, ho tšoarella le thepa e bobebe bakeng sa lits'ebetso tse joalo ka marulelo, marulelo le litsamaiso tsa fatše. Ka ho tsepamisa maikutlo ho ntseng ho hola ho litharollo tse tšoarellang le tse se nang tikoloho, li-resin tsa polyester tse sa tsitsang li fetohile lisebelisoa tsa khetho ho bahahi ba bangata le lihahi.

Kopana le Moetsi: Molekane oa Hao ea Tšepahalang oa Khoebo:

Re motlotlo ho ba molekane oa hau oa khoebo eo u e ratang 'me re u fa li-resine tsa polyester tsa boleng bo holimo. Re na le lifeme tsa rona Chaena, ho netefatsa hore lihlahisoa tsa rona li finyella litekanyetso tse phahameng ka ho fetisisa tsa boleng le ho tšepahala. Bokhoni ba rona bo matla ba tlhahiso bo re thusa ho fihlela litlhoko tsa hau tse ikhethileng le ho fana ka litharollo tse ikhethileng. Re ikemiselitse ho fihlela litlhoko tsa bareki ba rona, ho fana ka litšebeletso tse ntle tsa bareki, le ho theha likamano tsa nako e telele.

ha re phethela:

Ka bokhuts'oane, tlhokeho ea li-resine tsa polyester tse sa tsitsang bakeng sa lisebelisoa tsa ho beha matsoho tsa tora e pholileng e ntse e eketseha. Li-resin tsena li na le thepa e ntle haholo joalo ka matla a mochini, ho hanyetsa mocheso le ho folisa ka potlako, ho etsa hore e be tse loketseng lits'ebetso tse fapaneng tsa indasteri. Ka feme ea rona e Chaena, k'hamphani ea rona e ikemiselitse ho u fa resin e ntle ka ho fetisisa ea polyester e sa sebetseng bakeng sa litlhoko tsa hau. Selekane le rona 'me u bone boleng, bots'epehi le boitseanape boo re bo tlisang tafoleng.
