Roj Hmab yog cov khoom siv paub zoo uas siv hauv yuav luag txhua qhov ntawm tib neeg lub neej. Tshuaj, kev ua liaj ua teb, kev lag luam tsis tuaj yeem ua yam tsis muaj cov polymer no. Ntau cov txheej txheem tsim khoom kuj tseem siv roj hmab. Cov khoom no yog tsim los ntawm dab tsi thiab nws cov yam ntxwv yog dab tsi tau piav qhia hauv kab lus.

roj hmab yog dab tsi

Roj Hmab yog ib qho elastic polymer. Nws cov qauv yog sawv cev los ntawm randomly teem carbon chains tuav ua ke los ntawm leej faj atoms.

Nyob rau hauv lub xeev ib txwm, carbon chains muaj ib tug twisted tsos. Yog hais tias cov roj hmab yog stretched, cov pa roj carbon chains yuav unwind. Kev muaj peev xwm ncab thiab rov qab mus rau nws qhov qub zoo li qub tau ua cov roj hmab xws li cov khoom siv tsis tau hauv ntau qhov chaw.

Nws yog dab tsi? Feem ntau, roj hmab yog tsim los ntawm kev sib xyaw roj hmab nrog tus neeg sawv cev vulcanizing. Tom qab cua sov rau qhov xav tau kub, qhov sib tov thickens.

Qhov txawv ntawm roj hmab thiab roj hmab

Roj hmab thiab roj hmab yog siab molecular hnyav polymers muab los ntawm ntujlos yog synthetically. Cov ntaub ntawv no txawv ntawm lub cev thiab tshuaj lom neeg thiab kev tsim khoom. Cov roj hmab ntuj yog ib yam khoom tsim los ntawm cov kua txiv hmab txiv ntoo ntawm cov ntoo sov - latex. Nws ntws tawm ntawm lub cortex thaum nws puas lawm. Synthetic roj hmab yog tau los ntawm polymerization ntawm styrene, neoprene, butadiene, isobutylene, chloroprene, acrylic acid nitrile. Thaum cov roj hmab dag yog vulcanized, roj hmab yog tsim.

Cov roj hmab sib txawv yog dab tsi? Rau qee yam khoom siv hluavtaws, cov khoom siv organic yog siv kom tau txais cov khoom siv zoo ib yam rau cov roj hmab ntuj.

Rubber properties

Roj Hmab yog ntau yam khoom siv uas muaj cov khoom hauv qab no:

1. High elasticity - lub peev xwm loj rov qab deformation dhau qhov kub ntau yam.
2. Elasticity thiab zoo stability ntawm me deformations.
3. Amorphous - yooj yim deformed nrog me ntsis siab.
4. Nyob zeem muag.
5. Muaj zog thiab hnav tsis kam.
6. Nyob ntawm hom roj hmab, roj hmab tuaj yeem ua tus yam ntxwv ntawm dej, roj, roj av, tiv thaiv tshav kub thiab tiv thaiv cov tshuaj, ionizing thiab lub teeb hluav taws xob.

Roj hmab thaum kawg poob nws cov khoom thiab poob nws cov duab, uas tau tshwm sim los ntawm kev puas tsuaj thiab txo lub zog. Lub neej kev pab cuam ntawm cov khoom siv roj hmab yog nyob ntawm cov kev mob ntawm kev siv thiab tuaj yeem nyob ntawm ob peb hnub mus rau ntau xyoo. Txawm nrog kev khaws cia ntevroj hmab muaj hnub nyoog thiab yuav siv tsis tau.

YRubber production

Roj Hmab yog tsim los ntawm cov roj hmab vulcanizing nrog kev sib ntxiv ntawm cov khoom sib tov. Feem ntau, 20-60% ntawm cov txheej txheem ua tiav yog roj hmab. Lwm cov khoom ntawm cov roj hmab sib xyaw yog cov khoom ntim, cov tshuaj vulcanizing, accelerators, plasticizers, antioxidants. Dyes, fragrances, modifiers, hluav taws kub retardants thiab lwm yam khoom siv kuj tuaj yeem muab ntxiv rau qhov muaj pes tsawg leeg ntawm pawg. Cov txheej txheem ntawm cov khoom yog txiav txim siab los ntawm cov khoom tsim nyog, kev ua haujlwm, kev siv tshuab siv cov khoom siv roj hmab tiav thiab kev suav nyiaj txiag. Ua li no, cov roj hmab zoo yog tsim.

Cov khoom siv roj hmab semi-tiav yog dab tsi? Rau lub hom phiaj no, kev tsim khoom siv thev naus laus zis ntawm kev sib xyaw roj hmab nrog lwm cov khoom siv hauv cov khoom sib xyaw tshwj xeeb lossis cov chais tsim rau kev tsim cov khoom lag luam ib nrab, ua raws li kev txiav thiab txiav. Lub voj voog ntau lawm siv presses, autoclaves, nruas thiab qhov vulcanizers. Cov roj hmab sib xyaw yog muab cov yas siab, ua tsaug rau cov khoom yav tom ntej tau txais cov duab tsim nyog.

khoom siv roj hmab

Hnub no, roj hmab siv rau hauv kev ua kis las, tshuaj, kev tsim kho, kev ua liaj ua teb, thiab kev tsim khoom. Tag nrho cov khoom tsim los ntawm cov roj hmab ntau tshaj 60 txhiab ntau yam. Qhov nrov tshaj plaws ntawm lawv yog cov ntsaws ruaj ruaj, shock absorbers, raj, ntsaws ruaj ruaj, sealants, rubberized coatings, tig ntsej muag.cov ntaub ntawv.

Cov khoom siv roj hmab tau siv dav hauv kev tsim khoom. Cov khoom no tseem yog qhov tseem ceeb hauv kev tsim cov hnab looj tes, khau, siv tawv, cov ntaub tsis muaj dej, cov ntaub qhwv.

Ntau cov roj hmab tsim yog siv los ua cov log tsheb.

Roj hmab hauv log tsheb tsim

Roj hmab yog cov khoom tseem ceeb hauv kev tsim cov log tsheb. Cov txheej txheem no pib nrog kev npaj cov roj hmab sib xyaw los ntawm cov roj hmab ntuj thiab hluavtaws. Tom qab ntawd silica, soot thiab lwm yam tshuaj lom neeg ntxiv rau cov roj hmab loj. Tom qab sib tov tag nrho, qhov sib tov yog xa mus raws ib txoj siv conveyor mus rau qhov cub. Cov zis yog cov hlua roj hmab ntawm qhov ntev.

Nyob rau theem tom ntej, txoj hlua yog rubberized. Textile thiab hlau hlua yog ntim nrog cov roj hmab kub. Ua li no, sab hauv, textile thiab txoj siv tawv txheej ntawm lub log yog tsim.

Lub log tsheb yog dab tsi? Tag nrho cov log tsheb manufacturers siv ntau formulations thiab roj hmab manufacturing technologies. Txhawm rau muab cov khoom tiav tiav lub zog thiab kev ntseeg siab, ntau yam plasticizers thiab reinforcing fillers tuaj yeem ntxiv.

Tires yog tsim los ntawm cov roj hmab ntuj. Nws ntxiv rau cov roj hmab compound txo cov log tsheb cua sov. Feem ntau ntawm cov roj hmab compound yog hluavtaws roj hmab. Cov khoom no muab cov log tsheb elasticity thiab muaj peev xwm tiv taus cov khoom hnyav.
