Umhlinzeki onokwethenjelwa wezinto zokumanzisa

Umhlinzeki othembekile wezinto zokumanzisa Isithombe Esivelele

incazelo emfushane:

Izinto ezimanzisa izinto ezinciphisa ukucindezeleka koketshezi, okuvumela ukuthi lusabalale kalula. Zivame ukusetshenziswa ezinhlobonhlobo zezicelo, okuhlanganisa ukudla, izimonyo, ukwenza amaphepha, ukwelashwa ngamanzi, insipho, ukukhiqizwa koshukela, ukubilisa, ukumboza, ukuphrinta nokufaka idayi kwendwangu, ukubhoboza nokucwenga, uwoyela we-hydraulic kanye namafutha okugcoba aphezulu, izinto ezikhululayo, nezinye izici eziningi.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Izakhiwo Zomzimba Nezamakhemikhali

Izinto ezimanzisa, uhlobo lwe-polyorganosiloxane olunesakhiwo seketanga samazinga ahlukene e-polymerization, lusebenza njenge-agent emanzisa emangalisayo. Ikhiqizwa nge-hydrolysis ye-dimethyldichlorosilane namanzi ukuze kutholakale indandatho yokuqala yokujiya. Indandatho bese iyaqhekeka, ilungiswe ukuze kukhiqizwe indandatho ye-Chemicalbook ephansi, bese ihlanganiswa ne-agent eyinhloko kanye ne-catalyst ye-polymerization. Le nqubo iphumela ezinhlobonhlobo zezingxube ze-Wetting agents ezinamazinga ahlukene e-polymerization. Izingxenye ezibilayo eziphansi zisuswa nge-vacuum distillation ukuze kutholakale izinto zokugcina ezimanzisa.

Ngaphandle kokuba yinto yokumanzisa, uwoyela we-silicone unezinye izici eziningi kanye nezinhlelo zokusebenza. Uvame ukusetshenziswa njengesihlanzi ezimbonini ezifana nokucubungula ukudla, ukukhiqiza izimonyo, kanye nokwenza amaphepha. Ngokunciphisa ngempumelelo ukwakheka kwe-foam, uwoyela we-silicone uthuthukisa inqubo yokukhiqiza iyonke. Ngaphezu kwalokho, usetshenziswa njengesithako esiyinhloko ekudalweni kwe-silicone resin kanye nerabha ye-silicone. Lezi zinto zithola ukusetshenziswa okubanzi njengezinamathiseli, izithasiselo zepulasitiki ezivimbela ilangabi, izinto zokusetshenziswa zokuvikela umswakama, nokuningi.

Ukuguquguquka kwamafutha e-silicone kuboniswa kakhulu ngokusetshenziswa kwawo njenge-ejenti yokuqeda embonini yesikhumba. Kuyasiza ekuthuthukiseni ukubukeka, ukuthungwa, kanye nokuqina kwemikhiqizo yesikhumba. Ngaphezu kwalokho, kweminye imikhakha ehlukahlukene, njengokukhiqiza insipho esezingeni eliphezulu, ayisebenzi nje kuphela njenge-ejenti yokumanzisa kodwa futhi isebenza njengesithako esibalulekile sokwenza kanye nezinjongo zokuzinza.

Inzuzo

(1) Ukusebenza kwe-viscosity kungcono kakhulu ku-lubricant yoketshezi, kanti izinguquko ze-viscosity ekushiseni okubanzi zincane. Iphuzu layo le-condensate ngokuvamile lingaphansi kuka--50 ° C, kanti amanye afinyelela ku--70 ° C. Ligcinwa isikhathi eside ekushiseni okuphansi. Ukubukeka kanye ne-viscosity yemikhiqizo yalo kawoyela akukashintshi. Uwoyela oyisisekelo ocabangela izinga lokushisa eliphezulu, izinga lokushisa eliphansi, kanye nobubanzi bokushisa obubanzi.

(2) Ukuqina okuhle kakhulu kokushiswa kwe-thermal, njengokushisa kokubola kokushisa > 300 ° C, ukulahlekelwa okuncane kokushiswa kwe-evaporation (150 ° C, izinsuku ezingu-30, ukulahlekelwa kokushiswa kwe-evaporation kungu-2%) kuphela, ukuhlolwa kokushiswa kwe-epoxy (200 ° C, 72H), ukushintsha kwe-viscosity kanye nenani le-asidi Okuncane.

(3) Ukushisa okuhle kakhulu kukagesi, ukumelana nomthamo, njll. Ekushiseni okuvamile ～ 130 ℃, akushintshi (kodwa uwoyela awukwazi ukuba ngamanzi).

(4) Iwuwoyela ongenabo ubuthi futhi onegwebu eliphansi futhi onamandla wokulwa namagwebu, ongasetshenziswa njengesivikelo.

(5) Ukuqina okuhle kakhulu kokucheba, okungamunca ukudlidliza futhi kuvimbele ukudluliswa kokudlidliza.
