Makambani matsva eBonding ari kukura akadai seHTPB, EHTTPB, ATBN, HTBN, CTBN...

2024-05-29

Fekitori yedu itsva yakagadzira zvinhu zvinobatanidza, zvakaita se HTTPB, HTTPB, ATBN, HTBN, CTBN, nezvimwewo...

Zve HTTPB Sezvo hupamhi hwakanaka, kusviba kwakaderera, kuramba kukwegura, kushanda kwakaderera pakupisa, kuramba hydrolysis, kuramba acid nealkali, kuramba kupfeka uye kugona kwakanaka kwekudzivirira magetsi uye kushanda kwekugadzirisa kwakanaka. HTPB inogona kushandiswa muAdhesive, Sealents, Coatings, propellants (HTPB+AP+Al), nezvimwewo.

Cherechedza: Tinogona kugadzira chero shanduro yeHTTPB zvinoenderana nevatengi zvimwe zvinodiwa chikumbiro.

Zve HTTPB, EHTPB iHTPB molecular chain inounzira mapoka epoxy, ane zvakanakira zvakaita sekudzivirira mafuta, kuramba kukwegura, kujeka kwakanaka, uye kushanda zvakanaka kwekupisa kwakaderera. Mapoka ehydroxyl ari kumagumo kwecheni yemamorekuru uye mapoka ehydroxyl ari mucheni yemamorekuru Boka re epoxy iboka rinoita reactive rinogona kurapwa ne isocyanates dzakasiyana-siyana uye epoxy curing agents. Polymer yakagadziriswa ine hunhu hwakanaka hwemuviri nemakemikari, simba rakanaka rekunamatira kune zvinhu zvakasiyana-siyana zvisiri zvesimbi zvakaita sesimbi negirazi, hunhu hwakanaka hwe dielectric, mwero wakaderera wekupwanya, uye kuoma. Dhigirii repamusoro, rakagadzikana kusvika kualkali uye akawanda mavhoriyamu, rinogona kuvandudza zvakanyanya hunhu hwemakanika, simba rekunamira, uye kuramba kupisa kwezvinhu zve polyurethane.

EHTTPB inogona kushandiswa pakunamira, sealants, coatings, epoxy resin toughening, polyurethane elastomers, nezvimwewo.

Zve ATBN, ATBN irabha ye nitrile ine maamino functional groups kumativi ese e molecular chain, iyo inogona kurapwa ne isocyanate curing agents kana kuita ne epoxy groups kuti ikwanise kucheneswa. ATBN ine resistance yakanaka yemafuta, resistance kupisa, resistance kupera uye ine adhesion yakasimba. Inogona kuderedza tembiricha yegel uye resistance ye epoxy resin painosimbisa epoxy resin.

ATBN inonyanya kushandiswa sechinhu chinosimbisa epoxy resin, inogona kuwedzera kusimba kwezvinhu zvakasanganiswa, kuwedzera simba rekuchekerera uye simba rekusvuura, uye inogonawo kushandiswa sechinamira chakasiyana uye chinovhara.
