Iimicrospheres eziHollow cenospheres zezitywini zobushushu obuphezulu kunye nezinto ezincamathelayo

I-Cenospheres inokudlala iindima ezininzi kwii-sealants zobushushu obuphezulu kunye ne-adhesives. IiCenospheres zikhaphukhaphu, iingqukuva ezingenanto eziqulunqwe ikakhulu yisilica kunye nealumina, ezithi zifumaneke njengemveliso yokutsha kwamalahle kwizityalo zamandla. Xa ifakwe kwii-sealants kunye ne-adhesives,I-cenospheres inokubonelela ngeenzuzo ezahlukeneyo,ngakumbi kwizicelo zobushushu obuphezulu . Nazi ezinye iindima abazidlalayo:

Ukufakwa kwe-thermal : I-Cenospheres ineempawu ezigqwesileyo zokugquma ngenxa yolwakhiwo olungenamngxuma. Xa zongezwa kwii-sealants kunye ne-adhesives, zenza umqobo onciphisa ukuhanjiswa kobushushu, ngaloo ndlela unceda ukukhusela i-substrate okanye i-joint ukusuka kumaqondo okushisa aphezulu. Le propati yokufakelwa iluncedo ngokukodwa kwizicelo apho ukutshatyalaliswa kobushushu kufuneka kuncitshiswe.

Ukuxinana okuncitshisiweyo : Iicenospheres zikhaphukhaphu, oku kuthetha ukuba zinokunciphisa kakhulu ukuxinana okupheleleyo kwee-sealants kunye ne-adhesives xa zifakwe kwi-formulation yazo. Olu phawu lulula lunqweneleka kwizicelo apho ubunzima bezinto kufuneka buncitshiswe, njengakwi-aerospace okanye kwi-automotive applications.

I-rheology ephuculweyo : Ukongezwa kwee-cenospheres kunokuphucula iimpawu ze-rheological ze-high-temperature sealants kunye ne-adhesives. Benza njengama-thixotropic agents, oku kuthetha ukuba banokunceda ukulawula ukuhamba kunye ne-viscosity yezinto eziphathekayo. Le propati ivumela i-sealant okanye i-adhesive ukuba isetyenziswe ngokulula, isasazeke, kwaye ibambelele kwiindawo ngelixa igcina imilo yayo kunye nokuzinza.

Iipropati zomatshini eziphuculweyo : I-Cenospheres inokunyusa amandla omatshini kunye nokuchasana kwempembelelo ye-sealants kunye ne-adhesives. Xa zifakwe, zinokuqinisa izinto eziphathekayo, ziphucule ukuchasana noxinzelelo kunye nokuguqulwa. Le propati yokuqinisa inenzuzo ngokukodwa kwizicelo zokushisa okuphezulu apho izinto eziphathekayo zinokuthi zixhomekeke kwibhayisikile ye-thermal okanye uxinzelelo lomatshini.

Ukumelana nemichiza : I-Cenospheres inika ukuchasana kweekhemikhali okulungileyo, okwenza ukuba zilungele izicelo apho i-sealant okanye i-adhesive idinga ukumelana nokuvezwa kweekhemikhali ezahlukeneyo, i-acids, okanye i-alkalis. Banokunceda ukuphucula ukuchasana kweekhemikhali ngokubanzi kwezinto, ukunyusa ukuqina kwayo kunye nobomi.

Kubalulekile ukuqaphela ukuba iindima ezithile kunye neenzuzo ze-cenospheres kwi-high-temperature sealants kunye ne-adhesives zinokwahluka ngokuxhomekeke ekuqulunqweni, ukusetyenziswa, kunye nezinye izongezo ezisetyenziswa ngokudibeneyo nazo.
