Wazi kangakanani ngezici kanye nokusetshenziswa kwamafutha abicah?

Izindaba

Amafutha e-Siliconeinezici eziningi ezikhethekile, njengezinga lokushisa eliphansi le-viscosity coefficient, ukumelana namazinga okushisa aphezulu naphansi, ukumelana ne-oxidation, i-flash point, i-volatility ephansi, ukwahlukanisa okuhle, ukungezwani okuphansi kwendawo, akukho ukugqwala ezinsimbi, okungezona ubuthi, njll. Ngenxa yalezi izici, uwoyela we-silicone unokusebenza okuhle kakhulu ezinhlelweni eziningi. Phakathi kwamafutha e-silicone ahlukahlukene, uwoyela we-methyl silicone iwuhlobo olusetshenziswa kakhulu futhi olubaluleke kakhulu, kulandelwa uwoyela we-silicone we-methyl phenyl. Amafutha e-silicone asebenzayo ahlukahlukene kanye namafutha e-silicone ashintshiwe asetshenziselwa izinjongo ezikhethekile.

amafutha abicah
Umlingiswa: Uketshezi olungenambala, olungenaphunga, olungenabuthi, nolungaguquguquki.
Ukusetshenziswa: Ine-viscosities ehlukahlukene. Inokumelana nokushisa okuphezulu, ukumelana namanzi, ukwahlukanisa ugesi, kanye nokushuba kwesimo esiphansi. Okuvame ukusetshenziswa njengamafutha okugcoba athuthukisiwe, uwoyela we-shockproof, uwoyela wokufaka i-insulation, i-defoamer, i-ejenti yokukhulula, i-ejenti yokupholisha, i-isolation agent, namafutha epompo e-vacuum diffusion; I-lotion ingasetshenziselwa ukupholisha amathayi emoto, ukupholisha izinsimbi zezinsimbi, njll. Amafutha e-methyl abicah asetshenziswa kakhulu. Ukuqedwa okuthintekayo okubushelelezi nokuthambile kusetshenziswe ekuqedeni kwendwangu ngemva kokwenziwa kwe-emulsification noma ukuguqulwa. Amafutha e-silicone emulsified nawo afakwa ku-shampoo yemikhiqizo yokunakekelwa kwansuku zonke ukuze kuthuthukiswe ukugcotshwa kwezinwele. Ngaphezu kwalokho, kukhona i-ethylamafutha abicah, uwoyela we-silicone we-methylphenyl, i-nitrile equkethe uwoyela we-silicone, i-polyether modified silicone oil (amafutha abicah ancibilika emanzini), njll.
Uhla lokusetshenziswa kwamafutha e-silicone lukhulu kakhulu. Ayisetshenziswa nje kuphela njengento eyisipesheli kwezokundiza, ubuchwepheshe obusezingeni eliphezulu, kanye neminyango yezobuchwepheshe bezempi, kodwa futhi emikhakheni eyahlukene yomnotho wezwe. Ububanzi bokusebenza kwayo buye banda ukuze kube: ukwakhiwa, ugesi kanye nogesi, izindwangu, izimoto, imishini, ukwenziwa kwesikhumba nephepha, izimboni zamakhemikhali nezilula, izinsimbi nopende, imithi nokwelashwa, njalonjalo.
Izinhlelo zokusebenza eziyinhloko zeamafutha abicahkanye nokuphuma kwayo isikhiphi sefilimu, uwoyela okhipha i-shock, uwoyela we-dielectric, uwoyela we-hydraulic, uwoyela odlulisa ukushisa, uwoyela wepompo we-diffusion, i-defoamer, i-lubricant, i-hydrophobic agent, isithasiselo sikapende, i-agent yokupholisha, izimonyo kanye nesengezo sempahla yasendlini nsuku zonke, i-surfactant, izinhlayiya nefiber. i-ejenti yokwelapha, i-silicone grease, i-flocculant.

amafutha abicah.

Izinzuzo:
(1) Ukusebenza kwezinga lokushisa le-viscosity kuhamba phambili phakathi kwezithambisi eziwuketshezi, ezinoshintsho oluncane lwe-viscosity phezu kwebanga elibanzi lokushisa. Iphuzu layo lokuqina ngokuvamile lingaphansi kuka -50 ℃, kanti amanye angafinyelela phezulu aze afike ku -70 ℃. Uma igcinwe isikhathi eside emazingeni okushisa aphansi, ukubukeka kanye ne-viscosity yamafutha kuhlala kungashintshiwe. Kuwuwoyela oyisisekelo ocabangela amazinga okushisa aphezulu, aphansi, nabanzi.
(2) Ukuqina okuhle kakhulu kwe-oxidation eshisayo, njengezinga lokushisa elishisayo lokubola>300 ℃, ukulahleka okuncane kokuhwamuka (150 ℃, izinsuku ezingama-30, ukulahlekelwa ukuhwamuka okungu-2% kuphela, ukuhlolwa kwe-oxidation (200 ℃, amahora angama-72), izinguquko ezincane ku-viscosity ne-asidi. inani.
(3) Ukufakwa kukagesi okuhle kakhulu, ukumelana nevolumu, njll. akushintshi phakathi kwebanga lokushisa legumbi ukuya ku-130 ℃ (kodwa uwoyela awukwazi ukuqukatha amanzi).
(4) Ingamafutha angenabuthi, anegwebu eliphansi, futhi anamandla okulwa namagwebu angasetshenziswa njengesicoci.
(5) Ukuzinza kwe-shear okuhle kakhulu, okunomsebenzi wokumunca ukudlidliza nokuvimbela ukusakazwa kokudlidliza, kungasetshenziswa njengoketshezi olumanzi.
