Kusiyanisa pakati pechibhi rabha uye kurapwa rabara

Rabha inogona kuvapo mune mbiri huru nyika: mbichana mbichana uye akarapwa rabara.

Mbichana mbichana inoreva rabha iyo yakasanganiswa nevakaunganidzwa uye vakasvibisa asi vane kwete isati yadzvanya vulcanzation . Panguva ino, zvinyorwa zvichiramba zvichiratidzirisa zvepasi rose asi zvine Simba reMushini uye Elasticity . Pamusoro payo zvinowanzoita kunge yakaoma uye inonamira, uye iyo inoshaya maitiro ekuita anodiwa kune zvigadzirwa zvekupedzisira.

Akarapwa rabara , zvakare anozivikanwa se Vulcanization Rubber , inowanikwa mushure me Vulcanization Reaction , panguva iyo sulfu maatomu fomu kuyambuka-zvinongedzo pakati pemanyorerwo , zvichikonzera mu matatu-dimensional network dhizaini . Shanduko iyi inopa zvinyorwa Simba repamusoro, elasticity, kupisa kupesana, uye makemikari kugadzikana.

Vulcanized Rubber inoshandiswa zvakanyanya mukugadzira dzakasiyana siyana Zvikamu zveRabha , zvakaita se automotive mishonga yekudonha, Mechancal Solaling Mhete, tambo yetambo , uye Rubber Bearings . Izvi zvigadzirwa zvinochengetedza zvakanakisa elasticity uye kuisimbisa kuita pasi kupisa kwakanyanya, kumanikidzwa, kana zvemakemikari nharaunda , kuvaita zvakakosha zvinoshanda zvikamu muindasitiri maindasitiri.

Rubber inogonawo kutaurwa neiyo Yakatarisirwa kushandiswa mukati General-Chinangwa Rubber uye Special-Chinangwa Rubber:

General-Chinangwa Rubber zvinosanganisira Natural Rubber (NR), Butadiene rabara (br), Styrene-butadiene Rubber (SBR) , uye Isoprene rabara (ir).

Special-Chinangwa Rubber zvinosanganisira Fluororubber (fkm), Acrylic rabara (ACM), Chlosaulfonated polyethyle (csm), Chlorinated polyethylene (cpe), Silicone Rubber (VMQ), Polyether rabara (co, eco) , uye Polyurethane rubrabe (pu) . Izvi zvinowanzo shandiswa mukati Harsh kana nharaunda dzakasarudzika kuda Kupesana kwemafuta, kupisa kupesana, kana kupokana kwecorosi , kunyanya mukati Vulcanized Rubber zvikamu.

Panyaya yekuita, mbichana mbichana ane SIMBA YEMAHARA YEMAHARA, Kusimba, uye Kukwegura Kuparadzanisa , nepo akarapwa rabara kuratidzira a yakatsetseka, yakakwirira elasticity, uye yepamusoro mechanic zvinhu . Saka, Vulcanization ndiyo yakakosha maitiro ekugadzira Yakakwira-mhando rabha zvikamu nehupenyu hwakareba hwebasa uye zvakavimbika kuita.

Rabha inogona kuvapo mune mbiri huru nyika: mbichana mbichana uye akarapwa rabara.
