Itandukaniro riri hagati ya rubber karemano n'urubber ivanze

Rubber karemano ni polymer karemano ifite polyisoprene nk'igice cy'ingenzi. Formula yayo ya molekile ni (C5H8)n. 91% kugeza 94% by'ibiyigize ni hydrocarbons za rubber (polyisoprene), naho ibindi ni poroteyine, Ibintu bitari urubber nka aside liqueurs, ivu, isukari, nibindi. Rubber karemano ni yo rubber ikoreshwa cyane mu bikorwa rusange.
Rubber ivanze: Rubber ivanze bivuze ko ingano y'urubber karemano iri hagati ya 95% na 99.5%, kandi hongerwamo aside stearike nke, rubber ya styrene-butadiene, rubber ya butadiene, rubber ya isoprene, oxyde ya zinc, umukara wa karuboni cyangwa peptizer. Rubber ivanze yatunganyijwe.
Izina ry'Igishinwa: umupira w'ubukorikori
Izina ry'Icyongereza: umupira w'ubukorikori
Ibisobanuro: Igikoresho cyoroshye cyane gifite impinduka zishobora guhinduka zishingiye ku mvange za polymeri zikozwe mu buryo bwa sintetike.

●Ishyirwa mu byiciro rya rubber
Rubber igabanyijemo ibice bitatu: rubber karemano, rubber ivanze, na rubber ikoze mu buryo bwa sintetike.

Muri byo, ubwoko bw'ingenzi bw'urubura rusanzwe n'urubura ruvanze ni byo dutumiza mu mahanga muri iki gihe; uruvange rw'urubura rukozwe mu buryo bwa sintetike ruvuga uruvange rukomoka kuri peteroli, bityo ntabwo tuzarutekerezaho kugeza ubu.

Rubber karemano (rubber karemano) bivuga rubber ikozwe mu bimera bikora rubber karemano. Rubber ivanze ikorwa mu kuvanga rubber karemano n'urubber ruto rw'ubukorano hamwe n'ibindi bicuruzwa bya shimi.

● Rubber isanzwe

Rubber karemano igabanyijemo rubber isanzwe n'urupapuro rw'umucanga bitewe n'uburyo butandukanye bwo kuyikora. Rubber isanzwe ni rubber isanzwe. Urugero, rubber isanzwe yo mu Bushinwa ni rubber isanzwe yo mu Bushinwa, mu magambo ahinnye nka SCR, kandi kimwe na SVR, STR, SMR n'ibindi.

Kole isanzwe ifite kandi imiterere itandukanye, nka SVR3L, SVR 5, SVR10, SVR20, SVR 50… n'ibindi; bitewe n'ingano y'umubare, uko umubare uba munini, niko ubwiza burushaho kuba bubi; uko umubare uba muto, niko ubwiza burushaho kuba bwiza (ikintu cy'ingenzi cyo gutandukanya icyiza n'ikibi. Ikintu ni ivu n'umwanda biri mu gicuruzwa, uko ivu rigabanuka, niko ubwiza burushaho kuba bwiza).

Kole y'urupapuro rwacukuwe ni Ribbed Smoked Sheet, bivuze agace gato k'urupapuro rwacukuwe, mu magambo ahinnye nka RSS. Iyi ncamake itandukanye na kole isanzwe, kandi ntabwo ishyirwa mu byiciro hakurikijwe aho yakorewe, kandi imvugo ni imwe ahantu hatandukanye hakorerwa.

Hariho kandi ubwoko butandukanye bwa kole y'urupapuro rucukurwamo umwotsi, RSS1, RSS2, RSS3, RSS4, RSS5, kimwe, RSS1 nayo ni nziza cyane, RSS5 ni nziza cyane.

● Rubber ivanze

Ikorwa mu kuvanga no gutunganya rabu karemano hakoreshejwe rabu ntoya y’ubukorano n’ibindi bicuruzwa bya shimi. Uburyo bukoreshwa cyane mu kuvanga rabu ivanze ni ubu, nka rabu ivanze ya Maleziya yitwa SMR Compounded Rubber 97% SMR 20 (rabu isanzwe ya Maleziya) + 2.5% SBR (rabu ya styrene butadiene, rabu ikoze) + 0.5% aside stearic acid).

Rubber ivanze iterwa na rubber karemano igize igice cyayo cy'ingenzi. Yitwa ivanze. Nkuko byavuzwe haruguru, igice cy'ingenzi ni SMR 20, bityo yitwa imvange isanzwe ya rubber ya Maleziya No. 20; hari kandi imvange y'urusyo n'imvange isanzwe ya rubber.
