1. Yintoni i-silicone sealant?
I-silicone sealant yintlama eyenziwe nge-polydimethylsiloxane njengezinto eziphambili zokwenza imveliso, eyongezwa yi-crosslinking agent, i-filler, i-plasticizer, i-coupling agent, kunye ne-catalyst kwimeko ye-vacuum. Idlula kubushushu begumbi. Iphendula namanzi emoyeni ize iqine ukuze yenze irabha ye-silicone elastic.
2. Umahluko ophambili phakathi kwe-silicone sealant kunye nezinye izinto ezitywinayo eziphilayo?
Inamathela kakhulu, inamandla aphezulu okuxinana, imelana nemozulu, imelana nokungcangcazela, imelana nokufuma, imelana nevumba, kwaye iyakwazi ukuziqhelanisa notshintsho olukhulu lokubanda nobushushu. Idibene nokusebenza kwayo ngokubanzi, inokwenza ukuba inamathele phakathi kwezinto ezininzi zokwakha, olu luphawu oluqhelekileyo lwe-silicone sealant eyahlukileyo kwezinye izinto zokuncamathelisa ze-organic. Oku kungenxa yesakhiwo se-molecule yekhemikhali ye-silicone sealant. Ikhonkco eliphambili le-Si—O bond alonakaliswa lula yimitha ye-ultraviolet. Kwangaxeshanye, ubushushu bokutshintsha kweglasi yerabha ye-silicone buphantsi kakhulu kunobo bezinto eziqhelekileyo ze-organic. Isenokugcina ukuthamba okuhle phantsi kweemeko zobushushu obuphantsi (-50°C) ngaphandle kokuqhekeka okanye ukuqhekeka, kwaye akulula ukuyithambisa nokuwohloka phantsi kweemeko zobushushu obuphezulu (200°C). Ingagcina ukusebenza okuzinzileyo kuluhlu olubanzi lobushushu. I-silicone sealant nayo ayihambi ngenxa yobunzima bayo, ngoko ke ingasetyenziswa kwiindawo zokudibanisa iindonga eziphezulu okanye ezisemacaleni ngaphandle kokuwa, ukudilika okanye ukubaleka. Ezi mpawu zibalaseleyo ze-silicone sealants zisisizathu esibalulekileyo sokusetyenziswa kwayo ngokubanzi kwicandelo lokwakha, kwaye le mpawu ikwayinzuzo yayo ngaphezu kwezinye i-organic sealants.
3. Umahluko phakathi kwe-silicone sealant ye-neutral acid？
