Rabha yechisikigo inogona kukamurwa kuita inonamira yefodya, yakajairwa inonamira, crepe adhesive, uye latex zvinoenderana neyakasiyana maitirwo ekugadzira uye maumbirwo.Tobacco adhesive inosefa, yakaomeswa kuita matete mapepa nekuwedzera formic acid, yakaomeswa uye kuputa kugadzira Ribbed Smoked Sheet (RSS) . Rubber zhinji inotengwa kubva kuChina ndeyefodya inonamira, iyo inowanzoiswa mumapoka zvichienderana nekuonekwa kwayo uye yakakamurwa kuita nhanho shanu: RSS1, RSS2, RSS3, RSS4, RSS5, nezvimwewo. yakarongedzwa sechinhu chinonamira chekunze.Rabha yakajairwa ilatex yakasimbiswa uye yakagadziriswa kuita zvidimbu. Domestic natural rubber ndeye standard rabha, inozivikanwawo se particle rubber. Domestic standard adhesives (SCR) anowanzo kupatsanurwa zvinoenderana nepasi rose akabatana muviri uye makemikari zvimiro uye zviratidzi, izvo zvinosanganisira zvinhu zvinomwe: kusachena kwemukati, kukosha kwekutanga kwepurasitiki, chiyero chekuchengetedza mapurasitiki, nitrogen yemukati, inoshanduka zvinhu, madota emukati, uye ruvara index. Pakati pavo, tsvina yemukati inoshandiswa seconductivity index, uye yakakamurwa kuva mazinga mana zvichienderana nehuwandu hwetsvina: SCR5, SCR10, SCR20, SCR50, nezvimwewo, iyo yakaenzana neyokutanga, yechipiri, yechitatu, neyechina. level standard adhesives muChina.Iyo chaiyo rabha inowanikwa pamusika inonyanya kugadzirwa kubva kulatex kubva kune matatu mashizha erabha miti. 91% kusvika 94% yezvikamu zvayo irabha hydrocarbons, nepo zvimwe zvisiri zverabha zvinhu zvakaita semapuroteni, mafuta acids, madota, uye shuga. Natural rubber ndiyo inonyanya kushandiswa universal rubber.Natural rubber inogadzirwa kubva kulatex, uye chikamu chezvikamu zvisiri zverabha zviri mulatex zvinoramba zviri muvhu rakasimba rakasikwa. Kazhinji, rabha rechisikigo rine 92% kusvika 95% rabha hydrocarbons, nepo asiri erabha mahydrocarbon anoita 5% kusvika 8%. Nekuda kwenzira dzakasiyana dzekugadzira, mabviro, uye nemwaka wakasiyana wekukohwa rabha, chikamu chezvikamu izvi chinogona kusiyana, asi kazhinji chiri mukati mechikamu.Mapuroteni anogona kukurudzira vulcanization yerabha uye kunonoka kuchembera. Kune rumwe rutivi, mapuroteni ane mvura yakasimba yekunyura, iyo inogona kuunza rabha kuti itore unyoro uye mold, kuderedza kuvharidzira, uye zvakare kuve nekushata kwekuwedzera kupisa kwechizvarwa. antioxidants uye accelerators, nepo vamwe vanogona kubatsira kuparadzira zviwedzere zvehupfu panguva yekusanganisa uye kupfavisa raw raw.Ash rinonyanya kuve nemunyu senge magnesium phosphate uye calcium phosphate, ine shoma shoma yesimbi inosanganiswa semhangura, manganese, uye iron. Nokuti izvi zvakasiyana-siyana valence metal ions zvinogona kukurudzira kuchembera kwerabha, zvinyorwa zvayo zvinofanira kudzorwa.Kunyorova kwemvura murubha yakaoma hakupfuuri 1% uye kunogona kubuda panguva yekugadzirisa. Zvisinei, kana hunyoro hwehunyoro hwakanyanya, hahuiti chete kuti rubber yakasvibirira iite kuumbwa panguva yekuchengetedza, asiwo inokanganisa kushandiswa kwerubha, sekuda kwemaitiro ekugadzirisa agent kuti awedzere panguva yekusanganiswa; Munguva yekukunguruka uye extrusion maitiro, mabhuru anogadzirwa nyore, nepo panguva yevulcanization process, mabhuru kana chipanje senge zvimiro zvinogadzirwa.
