Kuphela 646: Ukucaciswa, GOST, ukwakheka

Kuphela 646 kuyinto kuphela ngempumelelo kakhulu jikelele, yenzelwe ukusetshenziswa lapho esebenza upende ezahlukene. Ngenxa it luthi alufane emva omiswe zithole kukhanye ezengeziwe. Kulesi sihloko uzofunda ukuthi:

- okuyinto kuphela 646;

- ezibekiweko lobuchwepheshe;

- Standard, izidingo zazo siyafana.

izici Jikelele kuphela

grade kuphela 646 - uketshezi esobala kungekho nto enemibala emihle (kwezinye izimo kungase kudingeke Tint aphuzi), elinesimo iphunga othize. inhlanganiso kuphela kuyinto 0.87 amagremu ngasinye cubic metres. Bheka, lokho akusho iqhwa futhi akuyona ukuthola viscosity. It wokhela angesabi ezingeni lokushisa 403 degrees namathumba at 59 degrees.

Manufactured ngokuhambisana nezidingo GOST 18188-172. I kuphela kufanele abe Ukwakheka iyunifomu. Akumele waphawula turbidity futhi delamination. Futhi akuvumelekile khona izinhlayiya imisiwe oketshezini.

Ikhishwa emaphaketheni ezimbonini uplastiki namabhodlela izitsha (amabhodlela) ezinobukhulu obuhlukahlukene.

Kuphela 646: Ukucaciswa, isakhiwo

Kuyinto elibona nxazonke oluyingozi izinto eziphilayo. I kuphela 646, izici okuyinto kuvumelana GOST 18188-72, kuhlanganisa izithako ezilandelayo:

• toluene - 50%;
• butanol - 15%;
• butyl acetate - 10%;
• ETHYL spirt- 10%;
• acetone - 7%;
• ethylcellosolve - 8%.

Ngenxa ngezithako zawo, kubhekwa ukuba ezimatasa Ukuqedwa impahla.

Kuphela 646 Ukucaciswa zimi kanje:

• Uyayazisa simo esishubile of ETHYL ether ku uhla kusuka 8 kuya ku-15;
• inombolo Coagulation elilingana okungenani 35%;
• inombolo acid ezingekho ngaphezu 0,06 mg Koh / g;
• ingxenye yamanzi (Fischer) ezingekho ngaphezu 2%;
• diluting isenzo - emva omiswe is hhayi waphawula khona mhlophe futhi ifilimu nitroenamels libhekene surface bushelelezi ngaphandle kobukhona amabala.

Lapho ukusebenzisa?

Kuphela 646 Ukucaciswa ukuvumela ukusetshenziswa ukusebenza ezihlukahlukene opende, kuhlanganise nitrocellulose, melaninoamidnymi, glyptal, acrylic, epoxy. Isetshenziselwa noma njengenhlangano okufakiwe ekukhiqizeni lezi zinto noma dilution kwabo ukuvumelana oyifunayo ngaphambi kokusetshenziswa. Futhi, reagent yengezwe yamathebhu kanye primer ngoba workability elikhulu, okuvumela ephelele yokululama ebusweni.

Kwezinye izimo, uketshezi R-646, okuyinto zivumelana Ukucaciswa STATE, isetshenziswa njengoba material for degreasing evele ahlukahlukene noma imishini yokuwasha (nokwandisa inqubo ethile).

Yiziphi izinzuzo kuphela ehlukene 646?

Phakathi izinzuzo main of sha 646 kuphela yilezi ezilandelayo:

• yizinhlobonhlobo libhekene;
• eliphezulu kakhulu amandla kuphela;
• ukunika ezengeziwe isicwebezelisi ezinengilazi;
• kulula ukuyisebenzisa;
• It akuveli uma contact ukusha phezu kwesikhumba;
• Ingeyona izindawo okunamafutha Laphezu ngayo;
• iyasha engashiyanga nephunga.

nokushintsha kokudla nokufakwa

I kuphela yengezwe upende noma ukuvenisha e izingcezu ezincane kuya ukuminyana oyifunayo futhi viscosity. ingxube Amazing ngaleyo ndlela kufanele njalo ibangele. Njengoba uketshezi has a umsebenzi omkhulu, nengisebenza kumelwe uqaphele ikakhulukazi ukumosha aphansi ungqimba enamathela.

siphephe uma ukusebenza kuphela

Kumele kwenziwe amakamelo ne komoya okuhle, ngoba ketshezi kuyinto enobuthi (labizwa ngokuthi yesithathu ekilasini ingozi). Ngaphezu kwalokho, uma usebenza nge amamaki kuphela 646 okumele asetshenziswe ezifana PPE njengoba ngomshini futhi amagilavu. It is ibuye Kunconywa ukusebenzisa izibuko zokuphepha.

Uma ejenti lalisendaweni kwesikhumba, kumele ziphathwe amanzi (efudumele) ngensipho. Uma ukuxhumana ulwelwesi lwamafinyila esweni emva ukuwasha kufanele kudokotela.

Njengoba sazi ukuthi kuphela sisetshenziselwa izinto ezingase zibambe umlilo, kubalulekile ukuba asingathe ngokucophelela futhi ngaphansi kwaziphi izimo ungavumeli evulekile amalangabi, izinhlansi nokubhema eduze amathangi ne reagent.

Indlela ukugcina?

I kuphela lagcinwa esitsheni uvalwe waqiniswa. Ngaphezu kwalokho, ne iziqukathi reagent kumele ivikelwe nomswakama, elangeni eliza ngqo futhi ukushisa. Awukwazi ukushiya noma yimaphi amadivaysi Ukushisa eduze ngokushesha zeziqukathi kuphela.

Sewaranti yesitoreji (njengoba abakhiqizi Imininingwane) kusukela ngosuku womshini izinyanga 12, okuyinto eyenza amabhizinisi ukuthenga mikhiqizo inqwaba.

Amanani lokushisa lapho kuphela lilondolozwe, uhla kusukela lokususa 40 plus 40 deg.
