Kutheni uSilane engozi?
1. Kutheni le nto ityhefu?
Ingaba yingozi nge-inhalation, ingenelele okanye ukufunxa kolusu. Ngokukodwa avuthanayo, gcina ubushushu, iintlantsi kwaye uvule amalangatye. Impazamo yayo ye-Inbulting iyacaphukisa amehlo, ulusu, i-mucous membrane kunye nephecana lokuphefumla eliphezulu. Nxiba iigloves ezifanelekileyo kunye neeglasi zokhuseleko kwaye uhlala usebenzisa i-hood ye-hood.
2. Zithini iziphumo zeSilane?
UQHAGAMSHELWANO: ISilane inokucaphukisa amehlo. I-Shinane Deanelition ivelisa i-Amorphouslica. Ukunxibelelana ngamehlo kunye ne-amorphous amasuntswana anokubangela ukucaphukisa.
Ukuphefumla: 1. Ukuphefumla koxinzelelo lweSilane kunokubangela intloko ebuhlungu, isicaphucaphu, isiyezi kunye nokukhuthaza iphecana lokuphefumla elingaphezulu.
I-Silane inokucaphukisa inkqubo yokuphefumla kunye ne-mucous membrane. Ukuphefumla okugqithisileyo kweSilane kunokubangela i-pneumonia kunye nesifo sezintso ngenxa yobukho besilwanyana se-crystalline.
③ Ukuvezwa kwegesi ephezulu kunokubangela ukutshiswa kwe-thermal ngenxa ye-quation.
I-Intences: I-Ingeneletion ayilindelekanga ukuba ibe yindlela yokuvezwa kweSilanes.
Uqhagamshelwano lolusu: uSilane uyacaphukisa ulusu. I-Shinane Deanelition ivelisa i-Amorphouslica. Unxibelelwano lwesikhumba kunye namasuntswana ase-Amorphous anokubangela ukucaphukisa.
3. Basetyenziselwa ntoni uSilanti?
A) Iarhente yokudibanisa:
I-OrganoFnofncination Alkoxants isetyenziselwa i-orlymers engatshatanga kunye nezixhobo ezingenazo, into eqhelekileyo yesi sicelo yoqiniswa. UMZEKELISO Zisetyenziswa ngenkqubo ye-thermose kunye ne-thermoplatistic. I-Mineral Fitlers enje nge: I-Silica, Talc, Woldnitote, udongwe kunye nezinye izinto ziphathwe kwangaphambili kunye ne-silanes kwinkqubo yokuxuba okanye yongezwa ngokuthe ngqo ngexesha lokuxuba.
Ngokusebenzisa i-organofraltountical kwi-Hydrophilic, iifilimu ezingeyo-firlec, iindawo ezineminerali ziye zasebenza kwaye zisebenza. Izicelo ze-fiberglass zibandakanya imizimba yemoto, izikhephe, izitali zeshawari, iibhodi zesekethe eziprintiweyo, i-TV yeTV eprintiweyo, imibhobho yepuzzle kunye nemibhobho yeplastiki nezikhongozelo, nabanye.
Iinkqubo ezaliswe ziiminerali zibandakanya i-Polyproplene ye-Polyproplene, emhlophe ye-carbon ye-silicon carbide, i-Pellet ye-Pellet Greyithi, i-Poly-bilis egcwele i-Polymotive, i-Shoe-Matshini egcwalisa irabha kunye nezinye iinkqubo.
B) Ukukhuthaza ubunetheko
Iiarhente zokudibanisa i-Silane zingabahlekisi bokukhuthazeka xa zisetyenziselwa ukubekwa ngo-Abehlohli kunye ne-Prims kwiPints, ii-IKK, iingubo, amayeza kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo kunye nezityholo. Xa isetyenziswa njengeyona nto ibalulekileyo, i-silanes kufuneka ifudukele kunxibelelwano phakathi kweqhina kunye nezinto eziphathwayo ziluncedo. Xa isetyenziswa njenge-primer, iiarhente zokudibanisa i-seling zisetyenziswa kwizixhobo ze-inrganic ngaphambi kokuba imveliso ibotshwe.
In this case: the silane is in a good position to act as an adhesion enhancer (in the interface area) With the correct use of silane coupling agents, even under harsh environmental conditions, the adhering inks, coatings, adhesives Or a sealant can keep the bond.
C) Amanzi e-Sulfur, abasasazekileyo
I-Siloxanes enamaqela e-hydrophobic amaqela aqhotyoshelweyo ancamathisela umlinganiswa ofanayo we-hydrophophic kwindawo engaphantsi kwe-hydnic, kwaye isetyenziswa njengeearhente ze-hydrophobic ezisisigxina ekwakhiweni, ibhulorho kunye nezicelo zokufezekisa. Zikwasetyenziswa kwi-hydrophobic podganic powders, zenza ukuba zibe nokuhamba nokukhululeka kwaye kulula ukusasaza kwi-polymers ephilayo kunye nolwelo.
D) Iarhente yokudibanisa
I-OrganoFnofncination Alkoxaal inokusabela nge-orlic polymers ukubandakanya amaqela e-AlKOXykyl kwi-polymer backbone. I-Silane emva koko inokuthi iphendule ngomswakama ukuze iwele i-silane ibe yi-SILONIT ye-SILOCHE YESIQINISEKISO SESIQINISEKISO SE-SILOSAAN. Le nkqubo inokusetyenziselwa ukuwela iplasitiki, i-polybethylene, kunye nezinye izinto ze-organic, ezinje ngee-acrylic kunye ne-polyurethanes, ukudlulisela iipeyinti ezinganyangekiyo, ezichasene namanzi, kunye nokubulala iingubo.
Iarhente ye-PSI-520 ye-SILAE isetyenziselwa ukusasazeka kwe-Pormb / Ah, i-Kaolin, i-Talcum Powder kunye nezinye izinto zefilimu, kwaye zilungele izixhobo ze-halogn. Ukunyangwa kwezixhobo ze-inorganic ze-inorganic, i-hydrophobility ifikelela kwi-98%, kunye ne-angle yamanzi kumphezulu we-organic powder i-organic powder yi-≥110º. Ingasasaza i-inorganic powder kwi-polymers ye-orlmed anjenge-resin, iplastiki kunye nerabha. Amanqaku: Ukuphucula ukusebenza kweeFliners; ukunyusa umda kwixabiso lesalathiso seoksijini (i-LOI); Ukonyusa i-hydrophobigo ye-filler, kwaye iphucule iPropathi yoMbane (iDelectric Hot, i-Bulk yoMbane), emva kokudibana kwamanzi; Ukonyusa inani le-filler, kwaye kwangaxeshanye kunamandla okuqina okuphezulu kunye ne-Elongations kwikhefu; ukuphucula ukumelana kobushushu kunye nobushushu obuphakathi obuphezulu; ukuphucula ukunganyangeki kwekhemikhali; Ukunganyangeki okuphezulu kwefuthe; Ukuphucula inkqubo yokuzinza kunye nemveliso yokuphumelela.
4. Ngawaphi amanyathelo okhuseleko kwigesi yeSilane?
Musa ukuvumela iqondo lobushushu lenkqubo lokuhlisa ngaphantsi -170 ° F (-112 ° C) okanye umoya unokutsalwa ukwenza umxube wokuqhushumba.
Musa ukuvumela uSilane ukuba udibane nee-hallides zentsimbi ezinzima okanye ii-halogens, uSilane uphendula ngobundlongondlongo. Inkqubo kufuneka icothwe ngononophelo ukuthintela iintsalela zamagqwirha, ii-halogens okanye ezinye ii-hydrocarbons ezikwi-chdrocarbons eziqulathwe kuyo.
Phinda ucofe inkqubo yokuvavanywa okuvuzayo kunye nezihlandlo ezithathu kuxinzelelo lokusebenza, ngokukhethekileyo i-Helufium. Ukongeza, inkqubo yokuchonga inkqubo yokuchonga kufuneka isekwe kwaye iphunyezwe.
Emva kokuba inkqubo ijongiwe ukuba ivule okanye ivule ezinye izizathu, umoya kwinkqubo kufuneka ihlanjululwe ngokuphuma okanye i-intert. Ngaphambi kokuvula nayiphi na inkqubo equlathe i-silane inkqubo kufuneka ihlanjululwe ngokupheleleyo ngegesi ye-Intert. Ukuba kukho nayiphi na indawo yenkqubo efileyo okanye iindawo apho kunokuhlala uSilane, kufuneka ikhutshiwe kwaye ijikelezwe.
I-SILAED kufuneka ikhutshelwe kwindawo enikezelwe kuyo, ngokukhethekileyo itshiswe. Nokuba ugxininiso olusezantsi lweSilane luyingozi kwaye akufuneki lutyhilwe emoyeni. I-SILADIN inokuvela emva kokuba ichithwe ngerhasi yerhasi ukuze ibenokutsha.
Iigesi ezicinezelweyo kufuneka zigcinwe kwaye zisetyenziswe ngokungqinelana neemfuno zeMveliso yaseMelika icinezele. Ekuhlaleni kusenokubakho imigaqo yezixhobo ezikhethekileyo zokugcina nokusetyenziswa kweemfuno zerhasi.
5. Nguwuphi umahluko phakathi kwesilika kunye neSilane?
Izinto ezisekwe kwisilika zihlala zinceda ezinye izicelo ezinokubakho kunezixhobo ezisekwe kwindalo, zisusela kwezo zisebenza kubushushu bexesha elide kwiimeko zokusingqongileyo. Zisetyenziswa njengezongezo ukubonelela ngomsebenzi, ukuxhathisa kwamanzi, kunye namava aphezulu okusebenza, ukwenza itekhnoloji ye-silicone into ebalulekileyo ekwenzeni izinto ezahlukeneyo zobomi bemihla ngemihla.
