Epoxy Resin

1、Nhanganyaya

Epoxy resin inowanzo shandiswa pamwe chete nezvimwe zvinowedzerwa. Zvinowedzerwa zvinogona kusarudzwa zvichienderana nemashandisirwo akasiyana. Zvinowedzerwa zvakajairika zvinosanganisira Curing Agent, Modifier, Filler, Diluent, nezvimwewo.

Mushonga wekupisa chinhu chinodiwa zvikuru. Kana epoxy resin ichishandiswa sechinamira, chinodzivirira, chinokandwa, kana semushonga wekupisa inofanira kuwedzerwa, zvikasadaro haigone kucheneswa. Nekuda kwezvinodiwa zvakasiyana zvekushandiswa uye mashandiro, kune zvinodiwa zvakasiyana zve epoxy resin, mushonga wekupisa, mugadziri, muzadzisi, musanganiswa nezvimwe zvinowedzera.

2,Kusarudzwa kweEpoxy Resin

(1) Sarudza zvinoenderana neApplication

① Kana ikashandiswa sechinamira, zviri nani kusarudza resin ine epoxy yepakati (0.25-0.45);

② Kana ikashandiswa seyakakandwa, zviri nani kusarudza resin ine epoxy yakawanda (0.40);

③ Kana ikashandiswa sejira, resin ine epoxy yakaderera (< 0.25) inowanzo sarudzwa.

(2) Sarudza zvinoenderana neSimba reMichina

Simba rayo rinoenderana nedanho rekubatanidza. Kukosha kwe epoxy kwakakwira, uye dhigirii rekubatanidza kwakakwirawo mushure mekuoma. Kukosha kwe epoxy kwakaderera uye dhigirii rekubatanidza kwakaderera mushure mekuoma. Kukosha kwakasiyana kwe epoxy kunokonzerawo simba rakasiyana.

① Resin ine epoxy yakawanda ine simba rakawanda asi inopfava;

② Resin ine epoxy yepakati ine simba rakanaka pakupisa kwakanyanya uye kwakaderera;

③ Resin ine epoxy shoma haina simba rakawanda kana tembiricha yakakwira.

(3) Sarudza zvinoenderana nezvinodiwa zvekushanda

① Kune avo vasingade simba uye vasingade kupisa kwakanyanya, vanogona kusarudza resin ine epoxy yakaderera iyo inogona kuoma nekukurumidza uye haisi nyore kurasika.

② Kune avo vanoda kupenya zvakanaka uye simba, vanogona kusarudza resin ine epoxy yakawanda.

3,Kusarudzwa kweMumiririri Anorapa

(1) Rudzi rweMushonga Unorapa:

Zvinhu zvinowanzo shandiswa pakurapa epoxy resin zvinosanganisira aliphatic amine, alicyclic amine, aromatic amine, polyamide, anhydride, resin uye tertiary amine. Pamusoro pezvo, pasi pesimba re photoinitiator, UV kana chiedza zvinogonawo kugadzira epoxy resin curing. Amine curing agent inowanzo shandiswa pakupisa tembiricha yemumba kana kupisa tembiricha yakaderera, nepo anhydride ne aromatic curing agent zvichinyanya kushandiswa pakupisa.

(2) Chipimo cheMushonga Unorapa

① Kana amine ikashandiswa semushonga wekubatanidza, inoverengerwa seinotevera:

Chiyero cheAmine = MG / HN

M = huremu hwemamorekuru eamine;

HN = nhamba yehydrogen inoshanda;

G = kukosha kwe epoxy (yakaenzana ne epoxy pa 100 g ye epoxy resin)

Chiyero chekuchinja hachipfuuri 10-20%. Kana chikarapwa neamine yakawandisa, resin inopwanyika. Kana chipimo chiri chidiki, kupora kwacho hakuna kukwana.

② Kana anhydride ikashandiswa se crosslinking agent, inoverengerwa seizvi:

Chiyero cheAnhydride = MG (0.6 ~ 1) / 100

M = huremu hwemamorekuru eanhydride;

G = kukosha kwe epoxy (0.6 ~ 1) ndiyo chiyero chekuedza.

(3) Nheyo Yokusarudza Mushonga Unorapa

① Zvinodiwa paKushanda.

Mimwe inoda kudzivirira kupisa kwakanyanya, mimwe inoda kuchinjika, uye mimwe inoda kudzivirira ngura zvakanaka. Mushonga wekupisa wakakodzera unosarudzwa zvichienderana nezvinodiwa zvakasiyana.

② Nzira yekurapa.

Zvimwe zvigadzirwa hazvigone kudziiswa, saka chinhu chinodziisa kupisa hachigone kusarudzwa.

③ Nguva yekunyorera.

Nguva inonzi yekushandiswa inoreva nguva inobva panguva iyo epoxy resin inowedzerwa pamwe chete nechinhu chinogadzirisa kupisa kusvika panguva iyo isingagone kushandiswa. Pakushandisa kwenguva refu, maanhydride kana zvinhu zvinogadzirisa kupisa zvakavanda zvinowanzo shandiswa.

④ Kuchengetedzeka.

Kazhinji, mushonga unoporesa usina chepfu yakawanda uri nani uye wakachengeteka kugadzirwa.

⑤ Mutengo.

4、Kusarudzwa kweModifier

Mhedzisiro yemugadziri wezvinhu ndeyekuvandudza kutsvuka kweganda, kuramba kuchekwa kwebvudzi, kuramba kukotama, kuramba kukanganiswa uye kushanda kwekudzivirira kwe epoxy resin.

(1) Zvinhu Zvinochinja Zvakajairika uye Hunhu

① Rabha rePolysulfide: rinovandudza simba remaburi uye kuramba kusvuuka;

② Polyamide resin: inovandudza kuputsika uye kunamira;

③ Polyvinyl alcohol TERT butyraldehyde: inovandudza kusimba kweganda;

④ NBR: kuvandudza kuramba kupiswa kweganda;

⑤ Phenolic resin: inovandudza kusimba kwekupisa uye kuramba ngura;

⑥ Polyester resin: inovandudza kusimba kweganda;

⑦ Urea formaldehyde melamine resin: inowedzera kuramba kwemakemikari uye simba;

⑧ Furfural resin: kuvandudza mashandiro ekukombama asingachinji, kuvandudza kuramba kweasidhi;

⑨ Vinyl resin: inovandudza kusimba kweganda uye simba rekurova;

⑩ Isocyanate: inoderedza kupenya kwemvura uye inowedzera kuramba mvura;

11 Silicone: inovandudza kusimba kwekupisa.

(2) Chipimo chemushonga

① Rabha yePolysulfide: 50-300% (ine mushonga unorapa);

② Polyamide resin uye phenolic resin: 50-100%;

③ Polyester resin: 20-30% (isina chinhu chinopedza kupisa, kana kuti ine chinhu chishoma chinopedza kupisa kuti ikurumidze kuita basa racho.

Kazhinji, kana modifier ikashandiswa zvakanyanya, kushanduka kwayo kunowedzera, asi tembiricha yekushanduka kwekupisa kwezvigadzirwa zve resin inoderera zvinoenderana. Kuti resin ivandudze kushanduka kwayo, zvinhu zvinosimbisa zvakaita se dibutyl phthalate kana dioctyl phthalate zvinowanzo shandiswa.

5、Kusarudzwa kweZvizadza

Basa remafiller nderekuvandudza zvimwe zvinhu zvezvigadzirwa uye mamiriro ekupisa kwe resin. Zvinogona zvakare kuderedza huwandu hwe epoxy resin uye kuderedza mutengo. Mafiller akasiyana anogona kushandiswa pazvinangwa zvakasiyana. Anofanira kunge ari pasi pe100 mesh, uye chiyero chinoenderana nekushandiswa kwawo. Mafiller akajairika ndeaya anotevera:

(1) Asbestos fiber negirazi fiber: zvinowedzera kusimba uye kuramba kusimba kwesimba;

(2) Upfu hweQuartz, upfu hweporcelain, upfu hwesimbi, simende, emery: kuwedzera kuomarara;

(3) Upfu hweAlumina neporcelain: kuwedzera simba rekubatanidza uye simba remuchina;

(4) Upfu hweAsbestos, upfu hwesilica gel uye simende inodziya zvakanyanya: inovandudza kusimba kwekupisa;

(5) Upfu hweAsbestos, upfu hwequartz uye upfu hwematombo: kuderedza mwero wekuderera kwesimba;

(6) Upfu hwearuminiyamu, upfu hwemhangura, upfu hwesimbi nedzimwe hupfu hwesimbi: zvinowedzera kufambiswa kwemhepo nekupisa;

(7) Graphite powder, talc powder uye quartz powder: inovandudza anti-wear performance uye lubrication performance;

(8) Emery nedzimwe mishonga yekukwesha: inovandudza mashandiro ekudzivirira kupfeka;

(9) Upfu hweMica, upfu hweporcelain uye upfu hwequartz: zvinowedzera kushanda kwekudzivirira kupisa;

(10) Mhando dzese dzepigments negrafiti: dzine ruvara;

Pamusoro pezvo, zvichienderana nedata, huwandu hwakakodzera (27-35%) hweP, As, Sb, Bi, Ge, Sn uye Pb oxides dzakaiswa muresin dzinogona kuchengetedza kunamira pasi pekupisa kwakanyanya uye kumanikidzwa.

6、Kusarudzwa kweDiluent

Basa remusanganiswa nderekuderedza viscosity uye kuvandudza kupenya kwe resin. Inogona kukamurwa kuita mapoka maviri asina simba uye anoshanda, uye huwandu hwacho kazhinji haupfuuri 30%. Musanganiswa wakajairika unosanganisira diglycidyl ether, polyglycidyl ether, propylene oxide butyl ether, propylene oxide phenyl ether, dicyclopropane ethyl ether, triethoxypropane propyl ether, inert diluent, xylene, toluene, acetone, nezvimwewo.

7、Zvinodiwa Zvekushandisa

Usati waisa mushonga wekupisa, zvese zvinoshandiswa, zvakaita se resin, mushonga wekupisa, filler, modifier, diluent, nezvimwewo, zvinofanirwa kuongororwa, izvo zvinosangana nezvinodiwa zvinotevera:

(1) Hapana mvura: zvinhu zvine mvura zvinofanira kutanga zvaomeswa, uye zvinonyungudutsa zvine mvura shoma zvinofanira kushandiswa zvishoma sezvinobvira.

(2) Kuchena: huwandu hwetsvina kunze kwemvura hunofanira kunge huri pasi pe1%. Kunyangwe ichigona kushandiswawo netsvina ye5%-25%, huwandu hwezvimwe zvinhu mufomura hunofanira kuwedzerwa. Zviri nani kushandisa reagent grade muhuwandu hushoma.

(3) Nguva Yekushanda: Zvakakosha kuziva kana zvinhu zvacho zvisiri kushanda.
