Natural rubber ndeye yakasikwa polymer musanganiswa ine polyisoprene sechinhu chikuru. Yayo molecular formula ndeye (C5H8) n. 91% kusvika 94% yezvikamu zvayo irabha hydrocarbons (polyisoprene), uye mamwe mapuroteni, Non-rabha zvinhu zvakadai semafuta acids, madota, shuga, etc. Natural rabha ndiyo inonyanya kushandiswa general-purpose rabha.
Composite rubber: Rubber inoumbwa inoreva kuti zviri murabha rechisikigo i95% -99.5%, uye shoma shoma ye stearic acid, styrene-butadiene rubber, butadiene rubber, isoprene rubber, zinc oxide, carbon black kana peptizer inowedzerwa. Yakanatswa compound rubber.
Zita rechiChinese: synthetic rubber
Zita reChirungu: synthetic rubber
Tsanangudzo: Chinhu chakanyanya elastic chine deformation inodzoreredzwa yakavakirwa pakugadzirwa kwepolymer komisheni.
●Kurongwa kwerubha
Rubha rinonyanya kukamurwa muzvikamu zvitatu: rabha rechisikigo, rabha rekomboni, uye rabha rekugadzira.
Pakati pazvo, rabha remusikirwo uye rabha yekomboni ndiyo mhando huru dzatinopinza kunze parizvino; synthetic rubber inoreva dziya dzakabviswa mupetroleum, saka isu hatingazvitarise panguva ino.
Natural rubber (nature rubber) zvinoreva rabha rakagadzirwa nezvinomera zvinogadzira rabha. Rabha yakasanganiswa inogadzirwa nekusanganisa rabha remusikirwo nerabha rekugadzira uye zvimwe zvigadzirwa zvemakemikari.
● Rabha chaiyo
Rabha rechisikigo rakakamurwa kuita rakajairwa rabha uye rinoputa pepa rabha zvinoenderana neakasiyana maitiro ekugadzira. Rabha yakajairwa ndiyo yakajairika rabha. Semuyenzaniso, yeChina yakajairwa rabha ndeye Standard rabha yeChina, yakapfupikiswa seSCR, uye zvakafanana kune SVR, STR, SMR zvichingodaro.
Gluu yakajairwa inewo magiredhi akasiyana, akadai SVR3L, SVR 5, SVR10, SVR20, SVR 50… nezvimwewo; maererano nehukuru hwenhamba, iyo yakakura nhamba, iyo yakaipisisa kunaka; iyo diki nhamba, zviri nani kunaka (chinhu chinonyanya kukosha kusiyanisa pakati pezvakanaka nezvakaipa Icho chinhu chiri madota uye kusachena kwechigadzirwa, zvishoma madota, zviri nani kunaka).
Smoked sheet glue is Ribbed Smoked Sheet, zvinoreva chimedu chitete cherabha inopfungaira, yakapfupikiswa seRSS. Ichi chipfupiso chakasiyana neyakajairwa glue, uye haina kurongeka zvichienderana nenzvimbo yekugadzira, uye kutaura kwakafanana munzvimbo dzakasiyana dzekugadzira.
Kune zvakare akasiyana mamakisi ekuputa pepa glue, RSS1, RSS2, RSS3, RSS4, RSS5, zvakafanana, RSS1 zvakare ndiyo yakanakisa mhando, RSS5 ndiyo yakaipisisa mhando.
● Rabha yakaumbwa
Inogadzirwa nekusanganisa nekunatsa rabha rechisikigo nerabha rekugadzira uye zvimwe zvigadzirwa zvemakemikari. Iyo inonyanya kushandiswa yerabha formula yekomboni ndeiyi, senge Malaysia's compound rabha SMR Compounded Rubber 97% SMR 20 (Malaysian standard rubber) + 2.5% SBR (styrene butadiene rubber, a synthetic rubber) + 0.5% stearic acid).
Compound rabha zvinoenderana nerabha rechisikigo rinoumba chikamu chayo chikuru. Inonzi komboni. Sezviri pamusoro, chikamu chikuru ndeye SMR 20, saka inonzi Malaysia No. 20 standard rubber compound; kune zvakare pepa rehutsi rinosanganiswa uye rakajairwa rabha musanganiswa.
