Kev taw qhia thiab kev siv VA-7|Vulcanizator VA-7
Rubber vulcanizing tus neeg saib xyuas yog hais txog ib hom tshuaj lom neeg uas tuaj yeem ua rau muaj kev sib txuas sib txuas hauv cov roj hmab molecular saw. Nws yog ib hom kev sib txuas tus neeg sawv cev thiab tseem hu ua tus neeg saib xyuas kev sib txuas hauv kev lag luam. Txij li thaum C. Goodyear pom tias cov roj hmab tuaj yeem sib txuas nrog cov sulfur hauv xyoo 1839, sulfur lossis sulfide tau siv los ua tus neeg sawv cev sib txuas hauv kev lag luam roj hmab. Cov txheej txheem no hu ua vulcanization. Sulfur thiab sulfides hu ua vulcanizing agents. Tom qab ntawd, nws tau pom tias ntxiv rau sulfur thiab sulfides, lwm cov organic peroxides, quinone compounds, hlau oxides, amine compounds, resins, selenium, tellurium, quinone oxime compounds, thiab lwm yam tuaj yeem sib txuas cov kab sib txuas ntawm cov roj hmab molecules. Tsim ib lub network peb-dimensional, yog li ntawd, lub sij hawm vulcanizing tus neeg sawv cev tsis txwv rau sulfides, tab sis feem ntau yog hais txog cov neeg ua hauj lwm uas muaj peev xwm cross-links roj hmab molecular chains, ua rau linear molecules tsim ib tug peb-dimensional network qauv, txo plasticity thiab nce. elasticity thiab lub zog. Cov tshuaj yog txhua yam hu ua vulcanizing agents, thiab lo lus vulcanization yuav tsum muaj lub ntsiab lus sib xws. Tsuas yog qee cov roj hmab thermoplastic uas tsis tas yuav tsum tau vulcanized, cov roj hmab ntuj thiab ntau yam hluavtaws roj hmab yuav tsum tau vulcanized nrog cov vulcanizing cov neeg ua haujlwm kom txhim kho cov khoom ntawm lub cev thiab txhua yam ntawm cov roj hmab.
Specification ntawm VA-7|Vulcanizator VA-7
Resins feem ntau yog siv hauv butyl roj hmab. Feem ntau siv yog phenol formaldehyde derivatives. Amine compounds feem ntau yog siv fluorine roj hmab thiab acrylic roj hmab. Feem ntau muaj xws li: triethylenetetramine, tetraethylenepentamine, hexamethylenediamine, 3,3′-dichlorobenzidine thiab triisopropanolamine, thiab lwm yam. Ester tebchaw yuav siv tau raws li vulcanizing agents rau butyl roj hmab, ntuj roj hmab, thiab styrene-butadiene roj hmab. Nws cov yam ntxwv yog yooj yim dispersion, ceev vulcanization ceev, thiab cov roj hmab vulcanized muaj zoo ozone kuj thiab kub tsis kam; nws qhov tsis zoo yog tias nws yooj yim rau scorch. Cov khoom siv feem ntau suav nrog p-quinonedioxime, 4,4'-dibenzoylquinonedioxime, tetrachlorobenzoquinone, poly-p-nitrosoquinone, hydroquinone diethoxy ether, thiab lwm yam. roj hmab, ethylene-propylene roj hmab thiab roj hmab sib xyaw ua ke, nws tuaj yeem ua tiav compression deformation tsawg, ceev vulcanization ceev thiab kav ntev. Cua kub hnub nyoog roj hmab. Piv txwv li, hauv NBR, thaum qhov ntau npaum li cas yog 1.5phr, qhov ruaj khov compression deformation tsuas yog 3-8%, uas tsis tuaj yeem ua tiav los ntawm kev siv lwm cov vulcanizing agents. Thaum cov tshuaj tiv thaiv scorch yog siv rau hauv chlorosulfonated polyethylene roj hmab, nws tuaj yeem ua ke nrog magnesium oxide, pentaerythritol thiab thiuram dipentamethylene tetrasulfide (TRA) los ua cov tshuaj tiv thaiv scorch; Txhawm rau txhim kho compression deformation, nws tuaj yeem ua ke nrog calcium hydroxide thiab thiuram tetrasulfide. Phenylethylenediamine yog sib xyaw ua ke los tsim cov kab mob maleimide vulcanization. Qhov ntau npaum li cas yog 2-4phr, uas tuaj yeem txo qis compression mus tas li deformation thiab txhim kho qhov kub thiab txias. Txhim kho lub zog sib txuas los txhim kho lub zog sib txuas ntawm cov roj hmab thiab polyamide ntaub, roj hmab thiab hlau, haum rau kev sib txuas ncaj qha. Sulfur-free vulcanizing tus neeg sawv cev yog siv rau cable roj hmab. Nws tuaj yeem hloov tag nrho cov sulfur-muaj vulcanizing cov neeg ua haujlwm xws li thiazole thiab thiuram. Nws daws qhov teeb meem ntawm kev sib kis ntawm tooj liab sulfide thiab blackening ntawm tooj liab xov hlau thiab tooj liab cov khoom siv hluav taws xob vim yog kev sib cuag nrog sulfur-muaj vulcanizing agents. Dosage: Siv los tiv thaiv scorch: 0.5-1.0phr Siv los ua vulcanizing tus neeg sawv cev: 2-3phr Siv los txhim kho compression deformation: 1.5phr Siv los txhim kho kev sib txuas lub zog: 0.5-5.0phr Lub Hom Phiaj Ntxiv rau cov roj hmab kom txo tau cov yas ntawm cov roj hmab nyoos, nce elasticity thiab lub zog, thiab tiv taus cov kuab tshuaj thiab tshuaj, thiab lwm yam.
