Umhlinzeki onokwethenjelwa wama-ejenti wokumanzisa

incazelo emfushane:

Izinto ezimanzisa izinto ezehlisa ukushuba kwamanzi oketshezini, eziluvumela ukuba lusakazeke kalula.Zivame ukusetshenziswa ezinhlobonhlobo zezicelo, ezihlanganisa ukudla, izimonyo, ukwenza iphepha, ukwelashwa kwamanzi, okokuhlanza, ukukhiqizwa kukashukela, ukuvutshelwa, ukunamathela, ukuphrinta izindwangu nokudaya, ukumba nokucwengisiswa, uwoyela we-hydraulic namafutha okugcoba ezinga eliphezulu, ama-release agents. , nezinye izici eziningi.

Ama-ejenti okumanzisa, uhlobo lwe-polyorganosiloxane enesakhiwo seketango lamadigri e-polymerization ahlukene, asebenza njenge-ejenti yokumanzisa emangalisayo.Ikhiqizwa nge-hydrolysis ye-dimethyldichlorosilane namanzi ukuze kutholwe indandatho yokuqala yokufingqa.Iringi bese iyaqhekeka, ilungiswe ukuze ikhiqize indandatho ephansi ye-Chemicalbook, bese ihlanganiswa ne-ejenti yekhanda kanye ne-catalyst ye-polymerization.Le nqubo iphumela ekuxubeni okuhlukahlukene kwe-ejenti yokumanzisa enamazinga ahlukahlukene e-polymerization.Izingxenye zokubilisa eziphansi zikhishwa nge-vacuum distillation ukuze kutholwe ama-ejenti wokugcina wokumanzisa.

Ngaphandle kokuba i-ejenti yokumanzisa, uwoyela we-silicone unenqwaba yezinye izici nezindlela zokusebenza.Isetshenziswa kaningi njenge-defoamer ezimbonini ezinjengokucubungula ukudla, ukukhiqiza izimonyo, nokwenza amaphepha.Ngokunciphisa ngempumelelo ukwakheka kwegwebu, uwoyela we-silicone uthuthukisa inqubo yokukhiqiza iyonke.Ukwengeza, isetshenziswa njengesithako esiyinhloko ekwakhiweni kwe-silicone resin kanye nerabha ye-silicone.Lezi zinto zithola ukusetshenziswa okubanzi njengama-adhesives, izithasiselo zepulasitiki ezibushelelezi ilangabi, izinto zokusetshenziswa ezivikelayo, nokunye.

Ukuguquguquka kwamafutha abicah kuboniswa futhi ngokuqashwa kwawo njenge-ejenti yokuqedela embonini yesikhumba.Isiza ekuthuthukiseni ukubukeka, ukuthungwa, nokuqina kwemikhiqizo yesikhumba.Ngaphezu kwalokho, kweminye imikhakha ehlukahlukene, njengokwenziwa komshini wokuwasha wekhwalithi ephezulu, awusebenzi nje njengendawo yokumanzisa kodwa futhi usebenza njengesithako esibalulekile sokwenza izinjongo zokuzinza.

Inzuzo

(1) Ukusebenza kwe-viscosity kungcono kakhulu ku-lubricant ye-liquid, futhi izinguquko ze-viscosity kuzinga lokushisa elibanzi zincane.Iphuzu layo le-condensate ngokuvamile lingaphansi kuka -50 ° C, kanti amanye afinyelela ku -70 ° C. Igcinwa isikhathi eside ekushiseni okuphansi.Ukubukeka kanye ne-viscosity yemikhiqizo yayo yamafutha akukashintshi.Ingamafutha ayisisekelo acabangela izinga lokushisa eliphezulu, izinga lokushisa eliphansi, kanye nebanga lokushisa elibanzi.

(2) Ukuqina okuhle kakhulu kwe-oxidation eshisayo, njengokushisa okushisayo kokubola> 300 ° C, ukulahleka okuncane kokuhwamuka (150 ° C, izinsuku ezingama-30, ukulahleka kokuhwamuka kungama-2%) kuphela, ukuhlolwa kwe-oxidation (200 ° C, 72H), i-viscosity ne-asidi izinguquko zenani Encane.

(3) Ukufakwa kukagesi okuhle kakhulu, ukumelana nevolumu, njll. Emazingeni okushisa ajwayelekile ～ 130 ℃, akushintshi (kodwa uwoyela awukwazi ukuba amanzi).

(4) Iwuketshezi olungenabuthi futhi luphansi-igwebu kanye namafutha aqinile e-anti-bubble, angasetshenziswa njengesifinyili.

(5) Ukuzinza kwe-shear okuhle kakhulu, okungabamba ukudlidliza futhi kuvimbele ukudluliswa kokudlidliza.
