Mmetụta nke vulcanization na nhazi na ihe onwunwe nke roba

Mmetụta nke vulcanization na nhazi na ihe onwunwe:

N'ime usoro mmepụta nke ngwaahịa rọba, vulcanization bụ usoro nhazi ikpeazụ. N'ime usoro a, rọba ahụ na-agafe usoro mmeghachi omume kemịkalụ dị mgbagwoju anya, na-agbanwe site na nhazi kwụ ọtọ gaa na nhazi ọdịdị ahụ, na-efunahụ ike nke rọba agwakọtara ma nwee nnukwu ike nke rọba ejikọtara ọnụ, si otú a na-enweta ihe onwunwe anụ ahụ na nke igwe dị mma, iguzogide okpomọkụ. Arụmọrụ, iguzogide ihe mgbaze na iguzogide nchara na-eme ka uru ojiji na oke ojiji nke ngwaahịa rọba dịkwuo mma.

Tupu vulcanization: nhazi ahịrị, mmekọrịta dị n'etiti molekul site na ike van der Waals;

Njirimara: nnukwu plasticity, ogologo oge dị elu, na mgbaze;

N'oge a na-eme ka ihe ghara ịdị mma: a na-amalite molekul ahụ, mmeghachi omume njikọta kemịkalụ na-emekwa;

Mgbe e mechara vulcanization: nhazi netwọk, intermolecular na njikọ kemịkalụ;

Nhazi:

(1) Njikọ kemịkalụ;

(2) Ọnọdụ nke njikọ njikọta;

(3) Ọkwa nke njikọta-mmekọrịta;

(4) Njikọta nkewa;

Njirimara:

(1) Njirimara igwe (ike ịgbatị ogologo mgbe niile. Ike siri ike. Ike nrụgide. Ogologo. Mgbatị);

(2) Njirimara anụ ahụ

(3) Nkwụsi ike nke kemịkalụ mgbe emechara vulcanization;

Mgbanwe na njirimara nke rọba:

Iji rọba eke dịka ihe atụ, site na mmụba nke ọkwa vulcanization;

(1) Mgbanwe na njirimara igwe (elasticity. Ike ndọda. Ike ịgbatị. Ike ndọda. Ike siri ike) mmụba (agbatị. Ntọala mkpakọ. Mmepụta okpomọkụ ike ọgwụgwụ) belata

(2) Mgbanwe na ihe ndị dị n'ahụ, ikuku na mmiri na-ebelata, enweghị ike ịgbaze, naanị ịza aza, melite iguzogide okpomọkụ

(3) Mgbanwe na nkwụsi ike kemịkalụ

Mmụba nkwụsi ike kemịkalụ, ihe kpatara ya

a. Mmeghachi omume njikọ-mmekọrịta na-eme ka otu ma ọ bụ atọm ndị na-arụ ọrụ kemịkalụ ghara ịdịkwa, na-eme ka o siere mmeghachi omume ịka nká ike ịga n'ihu

b. Nhazi netwọk ahụ na-egbochi mgbasa nke obere molekul, na-eme ka o siere radicals roba ike ịgbasa

Nhọrọ na Mkpebi nke Ọnọdụ Vulcanization nke Rọba

1. Nrụgide Vulcanization

(1) A ga-etinye nrụgide mgbe a na-eme ka ngwaahịa rọba ghara ịdị mma. Ebumnuche ya bụ:

a. Gbochie roba ahụ ka ọ ghara imepụta afụ ma melite ịdị nkọ nke roba ahụ;

b. Mee ka ihe roba ahụ na-asọ ma jupụta ebu ahụ iji mepụta ngwaahịa nwere ụkpụrụ doro anya

c. Meziwanye nrapado dị n'etiti oyi akwa ọ bụla (akwa na akwa ákwà ma ọ bụ akwa ígwè, akwa ákwà na akwa ákwà) na ngwaahịa ahụ, ma melite ihe ndị dị na ya (dịka iguzogide flexural) nke vulcanizate.

(2) N'ozuzu, a ga-ekpebi nhọrọ nke nrụgide vulcanization dabere na ụdị ngwaahịa, usoro, plasticity na ihe ndị ọzọ.

(3) N'ụkpụrụ, a ga-agbaso iwu ndị a: plasticity buru ibu, nrụgide kwesịrị ịdị obere; ọkpụrụkpụ ngwaahịa, ọnụọgụ nke oyi akwa, na nhazi mgbagwoju anya kwesịrị ibu ibu; nrụgide nke ngwaahịa dị gịrịgịrị kwesịrị ịdị obere, a pụkwara iji ọbụna nrụgide nkịtị mee ihe.

E nwere ọtụtụ ụzọ nke vulcanization na pressurization:

(1) Pampụ hydraulic ahụ na-ebufe nrụgide ahụ gaa na ebu ahụ site na vulcanizer dị larịị, wee bufee nrụgide ahụ gaa na ngwakọta roba site na ebu ahụ.

(2) Ihe na-eme ka ihe na-eme ka ihe dị n'ime ya sie ike (dịka uzuoku)

(3) Ikuku a na-etinye nrụgide

(4) Ịgba ọgwụ site na igwe ịgba ọgwụ

2. Okpomọkụ Vulcanization na oge ọgwụgwọ

Okpomọkụ vulcanization bụ ọnọdụ kachasị mkpa maka mmeghachi omume vulcanization. Okpomọkụ vulcanization nwere ike imetụta ọsọ vulcanization, ịdị mma ngwaahịa na uru akụ na ụba nke ụlọ ọrụ ahụ ozugbo. Okpomọkụ vulcanization dị elu, ọsọ vulcanization dị ngwa, arụmọrụ mmepụta dịkwa elu; ma ọ bụghị ya, arụmọrụ mmepụta dị ala.

Ịbawanye okpomọkụ vulcanization nwere ike ibute nsogbu ndị a;

(1) Na-akpata mgbawa nke yinye molekul roba na mgbanwe vulcanization, na-ebute mbelata na njirimara igwe nke ihe mejupụtara roba

(2) Belata ike nke ákwà dị na ngwaahịa rọba

(3) Oge ọkụ nke ihe mejupụtara roba ahụ dị mkpụmkpụ, oge njupụta ya belatara, ngwaahịa ahụ enweghịkwa gluu ụfọdụ.

(4) N'ihi na ngwaahịa ndị dị oke arọ ga-eme ka ọdịiche okpomọkụ dị n'etiti ime na mpụga nke ngwaahịa ahụ dịkwuo elu, na-ebute mmebi na-adịghị mma.
