Qhov science tom qab cov roj hmab vulcanization

Vulcanization yog dab tsi?

Vulcanization yog cov txheej txheem tshuaj lom neeg uas cuam tshuam nrog kev sib ntxiv ntawm cov leej txiv los yog lwm tus curatives mus rau roj hmab nyoos. Cov txheej txheem no tsim kev sib txuas ua ke ntawm polymer chains, ua rau cov khoom siv uas yog cov khoom siv dav ntau, ruaj khov, thiab tiv taus ib puag ncig ib puag ncig. Cov qib ntawm vulcanization tuaj yeem tswj kom ua tiav cov khoom siv tshwj xeeb tshwj xeeb, ua rau cov txheej txheem ntau rau ntau yam kev lag luam.

Tshuaj lom neeg muaj kev cuam tshuam nrog

Tus txheej txheem vulcanization feem ntau koom nrog kev tsim ntawm Sulfur Cross-txuas ntawm ntev ntev polymer chains ntawm roj hmab. Cov kab sib txuas no yog tsim los ntawm cov tshuaj tiv thaiv ntawm cov tshuaj lom neeg, xws li ntxiv, hloov chaw, thiab kev tshem tawm cov kev tawm tsam. Lub xub ntiag ntawm cov neeg soj ntsuam thiab cov neeg ua kom zoo tuaj yeem ua rau cov kev sib cuam tshuam ntau ntxiv, tso cai rau cov txheej txheem ntau lawm.

Hom Vulcanization

Muaj ntau hom txheej txheem vourcanization, txhua qhov haum rau cov ntawv thov sib txawv:

• Cov tshuaj tua tsis tau: Siv cov neeg Sulphurur thiab cov tshuaj ntsuam kom nrawm los tsim cov khoom sib txuas ntawm cov neeg hla kev Cross.

• Peroxide vulcanization: ua haujlwm cov organic peroxides rau cov ntawv thov kom muaj kev tiv thaiv muaj kub ua kom tsis kam.

• Kev ua hluav taws xob vulcanization: Siv hluav taws xob hluav taws xob hluav taws xob muaj zog hluav taws xob kom tsim cov ntawv hla, feem ntau siv hauv kev kho mob thiab kev lag luam kho mob.

Keeb kwm cov ntsiab lus ntawm vulcanization

Qhov nrhiav tau ntawm vulcanization

Cov txheej txheem ntawm vulcanization tau nrhiav pom los ntawm Charles Goodyear hauv 1839. Goodyear txoj kev sib xyaw ntawm cov roj hmab thiab cov leej twg yog cov khoom siv uas yog qhov ntsuas kub. Qhov no tawg hloov cov roj hmab kev lag luam, tso lub hauv paus rau cov ntawv thov niaj hnub.

Evolution ntawm Vulcanizents Techique

Tau ntau xyoo, kev siv tshuaj uas siv tau hloov zuj zus mus ntsib qhov kev xav tau ntawm ntau yam kev lag luam. Cov lus qhia ntawm cov tsuj taws thaum ntxov xyoo pua 20 tau tsom rau kev kho mob hauv eco-tus phooj ywg thiab cov hluav taws xob thiab peroxide vulcanization.

Kev siv cov ntaub ntawv ntawm cov roj hmab vulcanized

Kev Lag Luam Automotive

Kev lag luam automotive yog ib qho ntawm cov neeg siv khoom loj tshaj plaws ntawm cov roj hmab vulcanized. Cov log tsheb, cov ntsaws ruaj ruaj, thiab cov siv tawv yog siv cov roj hmab vulcanized, uas muab cov kev thov tsim nyog thiab elasticity rau cov kev siv ua tau zoo. Muaj peev xwm tiv thaiv huab cua sov thiab kev ntxhov siab ua tau ua rau cov roj hmab vulcanized indppPENSable hauv txoj haujlwm no.

Kev tsim kho thiab vaj tse

Hauv kev tsim kho, vulcanized roj hmab yog siv rau cov ntaub ntawv tais, waterproofing wee, thiab co kev sib cais cov ntaub qhwv. Nws txoj kev tawm tsam rau cov pejxeem ib puag ncig xws li UV hluav taws xob thiab ozone ua kom muaj kev ua tau ntev ntev hauv kev mob hnyav.

Kho Mob thiab Kho Mob

Kev lag luam kho mob pub rau cov roj hmab vulcanized rau cov khoom xws li phais cov hnab looj tes, cov caj ces, thiab ntsaws ruaj ruaj. Cov khoom siv biocompatibility thiab kuj txog rau cov txheej txheem kom tsis muaj menyuam ua kom nws zoo tagnrho rau kev siv tshuaj kho mob.

Cov Kev Sib Tw thiab Yav Tom Ntej

Kev txhawj xeeb ib puag ncig

Ib qho ntawm thawj txoj kev nyuaj ntsib txoj kev lag luam roj hmab yog ib puag ncig cuam tshuam ntawm vulcanization. Cov kev coj ua feem ntau koom nrog kev siv cov tshuaj lom thiab tsim cov khib nyiab. Cov kws tshawb nrhiav tau tshawb txog kev xaiv kom muaj kev xaiv, xws li Curatives thiab rov ua dua tshiab, los daws cov kev txhawj xeeb no.

Thev naus laus zis ua haujlwm

Kev nce qib hauv Nanotechnology thiab cov khoom siv tshawb fawb yog paving txoj kev rau cov txheej txheem volcanization tshiab. Piv txwv li, kev sib koom tes ntawm nanoparticles tuaj yeem txhim kho cov tshuab hluav taws xob ntawm cov roj hmab vulcanized, qhib kev tshiab rau cov ntawv thov kev ua tau zoo.
