I-Epoxidation ye-HTPB: Ukusebenza kunye nokusetyenziswa

I-Hydroxyl-terinated polybutadiene (HTPB)yipolymer eguquguqukayo eyaziwa ngeempawu zayo ezibalaseleyo, ubushushu obuphantsi beglasi yokutshintsha,

kunye nokuchasana okuphezulu kwiikhemikhali kunye nemozulu. Enye yeenkqubo eziphambili ekuguquleni i-HTPB ukuphucula iipropati zayo kukungcoliswa kwe-epoxidation. I-epoxidation

ye-HTPB ibandakanya ukongezwa kwamaqela e-epoxide kwi-polymer backbone, okubangela ukuba kubekho izinto ezilungisiweyo ezineempawu eziphuculweyo zokusebenza.

Eli nqaku liphonononga i-epoxidation ye-HTPB, ukusebenza kwayo, kunye nokusetyenziswa kwizicelo ezahlukeneyo.

Ii-epoxidation ye-hydroxyl-terinated polybutadiene (HTPB) linyathelo elibalulekileyo ekudityanisweni kwemathiriyeli ephucukileyo eneempawu eziphuculweyo.

Inkqubo ibandakanya ukusabela kwe-HTPB kunye ne-epoxidizing agent, efana ne-peracetic acid okanye i-hydrogen peroxide, ukwazisa amaqela e-epoxide kunye.

ikhonkco lepolymer. Olu hlengahlengiso lunika ukuphuculwa kokuchasana kweekhemikhali, ukunamathela, kunye nokuzinza kwe-thermal kwi-HTPB, okwenza ukuba ilungele indawo ebanzi.

uluhlu lwezicelo.

Enye yeenzuzo eziphambili zokusebenza zeHTPB epoxidized yimpawu zayo zokuncamathela ezongeziweyo. Ukuqaliswa kwamaqela e-epoxide kwandisa ukuhambelana

ye-HTPB ene-substrates eyahlukeneyo, ekhokelela ekuphuculeni ukunamathela kwi-adhesive kunye ne-sealant applications. Ukongeza, i-HTPB epoxidized ibonisa ukuxhathisa okugqwesileyo

kwizinyibilikisi, izibaso, kunye nee-oyile, nto leyo iyenza ibe lolona khetho lufanelekileyo lokwaleka, izinto zokuncamathelisa, kunye nezitywini kwindawo ezibango.

Ngaphezu koko, iukukhutshwa kwe-HTPB kukhokelela ekuphuculeni ukuzinza kwe-thermal kunye nokunciphisa umlilo. Ubukho bamaqela e-epoxide buphucula i-polymer's

ukumelana nobushushu kunye nomlilo, okwenza kube lula ukusetyenziswa kwi-aerospace, i-automotive, kunye nezicelo zokwakha apho ukhuseleko lomlilo luyingqwalasela ebalulekileyo.

Ukongeza, i-HTPB ene-epoxidized ingasetyenziswa njengesibophelelo kuqulunqo lwezixhobo ezidityanisiweyo eziphezulu zokusebenza, ezibonelela ngeempawu eziphuculweyo zomatshini.

kunye nokuqina.

Ngokusebenzisa,HTPB epoxidized ifumana izicelo kuluhlu olubanzi lwamashishini. Kwicandelo le-aerospace, isetyenziselwa ukwakhiwa kwezinto zokuncamathelisa,

iikhompawundi zembiza, kunye nezitywini zokubopha kunye nokutywina izinto ezibalulekileyo. Ukubambelela kwayo okugqwesileyo kunye nokumelana neekhemikhali kwenza kube lukhetho olufanelekileyo

izicelo ze-aerospace apho ukuthembeka kunye nokusebenza kubaluleke kakhulu.

Ngaphezu koko, kwishishini leemoto.HTPB epoxidizedisetyenziselwa ukuveliswa kweengubo, ii-sealants, kunye ne-encapsulants kumacandelo e-elektroniki kunye

izicelo phantsi kwe-hood. Isakhono sayo sokumelana nokuvezwa kulwelo lweemoto kunye neemeko zokusingqongileyo kuyenza ibe yeyona nto ithandwayo kwiimoto.

izicelo zokutywina kunye nokukhusela.

Ukongeza,HTPB epoxidizeduqeshwe kushishino lolwakhiwo ukwenza i-coatings ephezulu yokusebenza, i-adhesives, kunye ne-sealants ye-architectural,

ushishino, kunye nezicelo zeziseko zophuhliso. Ukuncamathela kwayo okuphezulu, ubume bemozulu, kunye nokumelana neekhemikhali kuyenza ibe yimathiriyeli ebalulekileyo ekukhuseleni nasekuphuculeni.

ukuqina kwezinto zokwakha.

Ukuqukumbela, iukukhutshwa kwe-HTPBiphumela kwisixhobo esilungisiweyo esineempawu zokusebenza eziphuculweyo, nto leyo eyenza ukuba ifaneleke kuluhlu olubanzi lwezicelo

kumashishini ahlukeneyo. Ukubambelela okuphuculweyo, ukuxhathisa kweekhemikhali, ukuzinza kwe-thermal, kunye nokubuyiswa komlilo we-HTPB epoxidized kuyenza ibe yinto ebalulekileyo

ukwenza iileyile eziphambili, izinto zokuncamathelisa, izinto zokutywina, kunye nemathiriyeli edibeneyo. Njengoko uphando kunye nophuhliso lokuguqulwa kwepolymer luqhubeka luqhubela phambili,

I-HTPB ene-epoxidized ilindeleke ukuba idlale indima ebalulekileyo kuphuhliso lwemathiriyeli esebenza kakhulu kwizicelo zamashishini ezahlukeneyo.
