Kukomeretsa bya reberi bifitanye isano rya hafi na sisitemu yo gushiraho.

Muri byombi Ibikoresho bya Rubber na Vietnam Rubber Ibice , gukomera ni kimwe mu bipimo by'ingenzi mu iterambere ry'imiterere y'ibicuruzwa, kugenzura ubuziranenge, hamwe n'ibice bya rubber bikora.

Gukomera Ibice bya Rubber ahanini biterwa:

Guhitamo Base Polymer

Sisitemu ya Gusubiramo

Gushimangira kuzunguruka

Plastistizers / softeners

Ibintu by'ingenzi bigira ingaruka ku nkombe gupima gukomera

1. Ingaruka zubunini

Kumena ubukana bipimwa n'ibyingenzi byinjira mukirenge.

Ubunini budahagije → Guhindura Byingenzi → Gusoma cyane

Ubunini bunini → Imyifatire mito → Gusoma Hasi

Kubwibyo, binini Ibikoresho bya Rubber Kurikiza cyane ibisabwa bisanzwe kugirango bibe byiza.

2. Ingaruka zikirenge cyamakambi

Ukurikije ibipimo, indenter igomba guhagarika MM,5 Kurenga umuvuduko.

Iyo ukanze kwicyuma cyangwa ikirahure, testers ikomeye igomba gusoma 100°.
Niba uburebure bwa plajection butandurwa, amakosa yo gupima gahunda abaho.
Rero, ibyemezo byabashinwa na Vietnam byangiza buri gihe hamwe.

3. Ingaruka zo kubeshya

Kwambara inama itambutse bihindura diameter, uhindure igitutu kuri buri gice.

Agace kanini gake → igitutu cyo hasi → Gusoma cyane

Abakora kashe ya reberi, amazu, hamwe na vibration aalator basanzwe basimbura ibitangwamo ibitangwamo kugirango bakomeze neza.

4. Ingaruka z'ubushyuhe

Rubber ni ubushyuhe: Ubushyuhe bwo hejuru buragabanya ubukana.

Sensitivite iratandukanye na polymer:

NR → Utumva neza

Cr, sbr → byoroshye

Inganda za Rubber na Vietnam ebyiri zisanzwe zigerageza gukomera kuri 23 ± 2 ° C..

5. Ingaruka zo gusoma

Nyuma yo gusimbuza indege hejuru ya rubber, Imyifatire ya CREDP ibaho:

Gusoma ako kanya → Agaciro keza

Gusoma neza → Agaciro kari hasi

Itandukaniro rishobora kuba Inkombe 5-7 a.
Kubwibyo, gusoma cyane mubisanzwe bifatwa mu isegonda 1 Nyuma yo gukanda.

UBURYO BWO GUKORESHA REBER

1. Guhindura byuzuye

Kongera imbaraga zuzuza byongera gukomera.

Ibigo binini-bikomeye → Ibirimo Byinshi Byuzuye Ibikubiyemo, Ibirimo Byoroheje

Ariko gutunganya biragoye

INYANDIKO itanga gakondo ibice byinshi .

2. Guhindura Ibisukura Sulfuru

Sulfuru nyinshi → Ihuza ryinshi → Gukomera.

Ibyiza:

Gushinyamirwa

Imikorere myiza yo gutunganya

Ibibi:

Kurwanya Ubushyuhe Bubi

Rero, Vietnam Rubber Ibice Koresha Ubu buryo bukurikirana ibikomoka ku bicuruzwa birwanya ubushyuhe.

3. Guhindura ibirimo plastistizer

Ibyiza kuri Ibice byoroshye munsi ya 60 ° a.

Plastizers yongera cyane guhinduka muri kashe yoroshye, gaskes, nibicuruzwa bipimisha.

Shingiro Ibikoresho bisanzwe bya rubber

Izi shingiro ndangagaciro zikora amakuru yingenzi kubitekerezo byabashinwa na Vietnam Bameb mugihe ushushanya.

Ingaruka z'abagorora / plastizers ku bikomeye

Guhinduka Guhinduka kuri 1 phr yongeyeho:

Fillers yongera imbaraga

FEF / HAF / EPC: +0.5

Amavuta ya Naphthenic / Amavuta ya paraffinic: –0.5

Amavuta meza: –0.588

Rubber Hardness Ertulation formula

Biteganijwe gukomera = shingira gukomera + (dosage × gukomera guhindura agaciro)

Iyi moderi yo kubara irakoreshwa cyane muri Ibikoresho bya rubber Munganda z'Abashinwa ndetse na Vietnam, bifasha guhanura byihuse no kwihutisha iterambere.

Kukomeretsa bya reberi bifitanye isano rya hafi na sisitemu yo gushiraho.
